AGENCY: Board of Governors of the Federal Reserve System (Board).

ACTION: Notice of Proposed Rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Board is inviting public comment on the models used to 
conduct the Board's supervisory stress test, changes to those models to 
be implemented in the 2026 stress test, and proposed changes to enhance 
the transparency and public accountability of the Board's stress 
testing framework (the proposal). The proposal would amend the Policy 
Statement on the Scenario Design Framework for Stress Testing, 
including to implement guides for additional scenario variables, and 
the Stress Testing Policy Statement. The proposal would also codify an 
enhanced disclosure process under which the Board would annually 
publish comprehensive documentation on the stress test models, invite 
public comment on any material changes that the Board seeks to make to 
those models, and annually publish the stress test scenarios for 
comment. Lastly, the proposal would make changes to the FR Y-14A/Q/M to 
remove items that are no longer needed to conduct the supervisory 
stress test and to collect additional data to support the stress test 
models and improve risk capture.

DATES: Comments must be received on or before January 22, 2026.

ADDRESSES: You may submit comments, identified by Docket No. R-1873 and 
RIN 7100-AH05, by any of the following methods:

I. Introduction

    In December 2024, the Board announced that it would propose 
significant changes to improve the transparency of the supervisory 
stress test and reduce the volatility of resulting capital 
requirements.\1\ The Board noted it planned to propose changes to 
disclose and seek public comment on the models that determine the

[[Page 51857]]

hypothetical losses and revenue of banks under stress and ensure that 
the public can comment on the hypothetical scenarios used annually for 
the test, before the scenarios are finalized. With this proposal, the 
Board is inviting public comment on the comprehensive model 
documentation for the 2026 stress test, as well as proposed changes to 
the models relative to the 2025 stress test. The comprehensive model 
documentation is available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. The Board is inviting comment 
on the proposed scenarios for the 2026 stress test through a separate 
notice.
---------------------------------------------------------------------------

    \1\ See Board, Press Release (Dec. 23, 2024), https://www.federalreserve.gov/newsevents/pressreleases/bcreg20241223a.htm. 
In February 2025, the Board reiterated its previous announcement 
that it would begin the public comment process on changes to the 
supervisory stress test. See Board, Press Release (Feb. 5, 2025), 
https://www.federalreserve.gov/newsevents/pressreleases/bcreg20250205a.htm.
---------------------------------------------------------------------------

    This proposal seeks to improve the transparency and public 
accountability of the supervisory stress test, while ensuring that the 
stress test remains an effective tool for understanding and assessing 
risk and retaining appropriate risk sensitivity and risk capture in 
capital requirements.
    The Board periodically reviews its regulations, including 
transparency efforts surrounding its regulations, to ensure they 
continue to achieve their goals in an effective and efficient manner. 
In addition to the changes discussed herein, the Board is also 
considering the effectiveness of its regulatory capital and capital 
planning requirements for large firms to ensure they remain cohesive 
and effective, maintain the resilience of the banking sector, and 
minimize any unnecessary burden. If appropriate, the Board will make 
changes to its rules through the public notice and comment process.
    Question 1: The Board seeks comment on all aspects of the proposal. 
What, if any, other elements of the supervisory stress test framework 
should the Board consider amending to improve the transparency, public 
accountability, and effectiveness of the supervisory stress test? For 
example, the Board could instead transliterate the models used to 
conduct the stress test and codify these transliterations in its 
regulations. What would be the advantages and disadvantages of this 
approach or other approaches the Board could consider?

II. Background on Stress Testing Framework, Stress Test Models, and 
Scenario Design Framework

A. Stress Testing Framework

    Congress enacted the Dodd-Frank Wall Street Reform and Consumer 
Protection Act (Dodd-Frank Act) in the wake of the 2007-09 financial 
crisis.\2\ Section 165 of the Dodd-Frank Act, as amended by section 401 
of the Economic Growth, Regulatory Relief, and Consumer Protection 
Act,\3\ requires the Board to establish enhanced prudential standards 
for nonbank financial companies supervised by the Board and bank 
holding companies with $250 billion or more in total consolidated 
assets.\4\ The purpose of these enhanced prudential standards is to 
prevent or mitigate risks to the financial stability of the United 
States that could arise from the material financial distress or 
failure, or ongoing activities, of large, interconnected financial 
institutions.
---------------------------------------------------------------------------

    \2\ Dodd-Frank Wall Street Reform and Consumer Protection Act, 
Public Law 111-203, 124 Stat. 1376 (2010).
    \3\ Economic Growth, Regulatory Relief, and Consumer Protection 
Act, Public Law 115-174, 132 Stat. 1296 (2018).
    \4\ See 12 U.S.C. 5365(a). In addition, the International 
Lending Supervision Act of 1983 provides the Board with broad 
discretionary authority to set minimum capital levels for state 
member banks and certain affiliates of insured depository 
institutions, including holding companies, supervised by the Board. 
See 12 U.S.C. 3902(1); 3907(a); 3909(a). Under section 5(b) of the 
Bank Holding Company Act of 1956 (Bank Holding Company Act), the 
Board may issue such regulations and orders relating to capital 
requirements of bank holding companies as may be necessary for the 
Board to carry out the purposes of the Bank Holding Company Act. 12 
U.S.C. 1844(b). Foreign banking organizations with a U.S. branch, 
agency, or commercial lending company subsidiary are made subject by 
the International Banking Act of 1978 (International Banking Act) to 
the provisions of the Bank Holding Company Act in the same manner as 
bank holding companies, see 12 U.S.C. 3106; therefore, the Board is 
also authorized under section 5(b) of the Bank Holding Company Act 
to impose these requirements on those foreign banking organizations, 
including on their U.S. operations. Similarly, with regard to 
savings and loan holding companies, section 10(g) of the Home 
Owners' Loan Act authorizes the Board to issue such regulations and 
orders relating to capital requirements as the Board deems necessary 
and appropriate to carry out the purposes of the Home Owners' Loan 
Act. See 12 U.S.C. 1467a(g)(1).
---------------------------------------------------------------------------

    Section 165(i)(1) of the Dodd-Frank Act requires the Board to 
conduct an annual supervisory stress test of nonbank financial 
companies supervised by the Board and bank holding companies with $250 
billion or more in total consolidated assets to evaluate whether the 
firm has the capital, on a total consolidated basis, necessary to 
absorb losses as a result of adverse economic conditions.\5\ Section 
401(e) of the Economic Growth, Regulatory Relief, and Consumer 
Protection Act requires the Board to conduct periodic stress tests for 
bank holding companies with total consolidated assets between $100 
billion and $250 billion.\6\ Section 165(i)(1) of the Dodd-Frank Act 
requires the Board to publish a summary of the supervisory stress test 
results.\7\ In 2012, the Board adopted a final rule implementing the 
stress test requirements established in the Dodd-Frank Act.\8\

    \8\ See 77 FR 62378 (Oct. 12, 2012).
---------------------------------------------------------------------------

    The Dodd-Frank Act also requires bank holding companies with $250 
billion or more in total consolidated assets, as well as nonbank 
financial companies supervised by the Board, to conduct company-run 
stress tests on a periodic basis.\9\ Under the Board's rules, firms 
subject to Category I, II, or III standards must conduct company-run 
stress tests.\10\ Company-run stress tests provide forward-looking 
information to supervisors to assist in their overall assessments of a 
firm's capital adequacy, help to better identify downside risks and the 
potential impact of adverse outcomes on the firm`s capital adequacy, 
and assist in achieving the financial stability goals of the Dodd-Frank 
Act. Further, the company-run stress tests help improve firms' stress 
testing practices with respect to their own internal assessments of 
capital adequacy and overall capital planning.
---------------------------------------------------------------------------

    \9\ 12 U.S.C. 5365(i)(2).
    \10\ See 84 FR 59032 (Nov. 1, 2019); 12 CFR 238.142; 12 CFR 
252.53. State member banks with average total consolidated assets of 
greater than $250 billion must also conduct company-run stress 
tests. 12 CFR 252.13.
---------------------------------------------------------------------------

    Each June, the Board publishes the results of its annual 
supervisory stress test, including each firm's projected capital 
ratios, pre-tax net income, losses, revenues, and expenses, under 
hypothetical, severely adverse economic and financial conditions.\11\ 
These disclosures provide the public with valuable information about 
each firm's financial condition and the ability of

[[Page 51858]]

each firm to absorb losses considering a stressful economic 
environment.
---------------------------------------------------------------------------

    \11\ A firm subject to Category I through III standards must 
participate in the supervisory stress test every year, while a firm 
subject to Category IV standards is generally required to 
participate only every other year. See 12 CFR 217.2; 12 CFR 238.10; 
12 CFR 252.5; 84 FR 59032 (Nov. 1, 2019). In 2019, the Board adopted 
rules establishing four categories of prudential standards for U.S. 
banking organizations with total consolidated assets of $100 billion 
or more and foreign banking organizations with combined U.S. assets 
of $100 billion or more. See 12 CFR 217.2; 12 CFR 238.10; 12 CFR 
252.5; 84 FR 59032 (Nov. 1, 2019). Category I standards apply to 
U.S. GSIBs and their depository institution subsidiaries. Category 
II standards apply to banking organizations with at least $700 
billion in total consolidated assets or at least $75 billion in 
cross-jurisdictional activity and their depository institution 
subsidiaries. Category III standards apply to banking organizations 
with total consolidated assets of at least $250 billion or at least 
$75 billion in weighted short-term wholesale funding, nonbank 
assets, or off-balance sheet exposure and their depository 
institution subsidiaries. Category IV standards apply to banking 
organizations with total consolidated assets of at least $100 
billion that do not meet the thresholds for a higher category and 
their depository institution subsidiaries.
---------------------------------------------------------------------------

    Following the 2007-09 financial crisis, the Board also made changes 
to its capital rule to address weaknesses observed during the 
crisis.\12\ These changes included the establishment of a minimum 
common equity tier 1 capital requirement and a fixed capital 
conservation buffer equal to 2.5 percent of risk-weighted assets.\13\ 
Large firms also became subject to a countercyclical capital buffer 
requirement, and the largest and most systemically important firms--
global systemically important bank holding companies, or GSIBs--became 
subject to an additional capital buffer based on a measure of their 
systemic risk, the GSIB surcharge.\14\ In 2020, the Board adopted the 
stress capital buffer requirement for certain firms.\15\ Because a 
firm's stress capital buffer requirement is informed by the firm's 
performance under the hypothetical economic conditions modeled by the 
supervisory stress test, each firm's stress capital buffer requirement 
is tailored to its risk profile.
---------------------------------------------------------------------------

    \12\ See generally 12 CFR part 217.
    \13\ See 78 FR 62018 (Oct. 11, 2013); 12 CFR 217.11.
    \14\ See 80 FR 49082 (Aug. 14, 2015).
    \15\ In 2020, the Board finalized a rule to integrate 
supervisory stress test results into the capital framework, through 
the stress capital buffer requirement. See 85 FR 15576 (Mar. 18, 
2020). The stress capital buffer requirement is calculated as the 
difference between a firm's starting and lowest projected common 
equity tier 1 capital ratio under the severely adverse scenario in 
the supervisory stress test plus four quarters of planned common 
stock dividends, expressed as a percentage of risk-weighted assets. 
See 12 CFR 225.8(f); 12 CFR 238.170(f). The stress capital buffer 
requirement framework generally applies to firms with $100 billion 
or more in total consolidated assets.
---------------------------------------------------------------------------

    Supervisory stress testing and stronger capital requirements have 
significantly improved the resilience of the U.S. banking system. Since 
2009, the common equity capital ratios of firms subject to the test 
have more than doubled, with common equity capital of such firms 
increasing by over $1 trillion.\16\ Since 2020, the supervisory stress 
test results have also informed a firm's stress capital buffer 
requirement. Greater transparency would allow firms to better 
understand the capital requirements associated with investment and 
expansion of different business lines and would facilitate more 
effective long-term capital planning. This, in turn, could enhance 
firms' ability to supply credit to households and businesses, 
ultimately supporting economic growth and financial stability.

B. Prior Supervisory Stress Disclosures and Policy Statements

    In addition to the annual stress test results disclosure, the Board 
has historically published some information about the supervisory 
stress test scenarios and models.
Scenarios
    The Board's stress test rules provide that the Board will notify 
firms, by no later than February 15 of each year, of the scenarios that 
the Board will apply to conduct its annual supervisory stress test and 
that firms must use to conduct their company-run stress tests.\17\ The 
Board also provides a narrative description of the scenarios no later 
than February 15 of each calendar year.\18\
---------------------------------------------------------------------------

    \17\ See 12 CFR 238.132(b); 12 CFR 238.143(b); 12 CFR 252.14(b); 
12 CFR 252.44(b); 12 CFR 252.54(b).
    \18\ See, e.g., Board, 2025 Stress Test Scenarios (Feb. 2025), 
https://www.federalreserve.gov/publications/files/2025-stress-test-scenarios-20250205.pdf.
---------------------------------------------------------------------------

    In 2013, the Board increased the transparency of the scenarios by 
finalizing the Policy Statement on the Scenario Design Framework for 
Stress Testing (Scenario Design Policy Statement), which articulated 
the Board's approach to scenario design for the supervisory and 
company-run stress tests, outlining the characteristics of the stress 
test scenarios, and explaining the considerations and procedures that 
underlie the formulation of these scenarios.\19\ The Scenario Design 
Policy Statement also described the baseline and severely adverse 
scenarios, the Board's approach for developing these two macroeconomic 
scenarios, and the approach for developing any additional components of 
the stress test scenarios. The Scenario Design Policy Statement 
explained that the severely adverse scenario is designed to reflect 
conditions that have characterized post-war U.S. recessions (the 
recession approach). Historically, recessions have typically featured 
increases in the unemployment rate, contractions in aggregate incomes 
and economic activity, and declines in inflation and interest rates.
---------------------------------------------------------------------------

    \19\ 12 CFR part 252, Appendix A.
---------------------------------------------------------------------------

    In the 2013 Scenario Design Policy Statement, the Board explained 
that, in light of the typical co-movement of measures of economic 
activity during economic downturns, such as the unemployment rate and 
gross domestic product, the Board would first specify a path for the 
unemployment rate and then develops paths for other measures of 
activity broadly consistent with the course of the unemployment rate in 
developing the severely adverse scenario. The 2013 Scenario Design 
Policy Statement also stated that economic variables included in the 
scenarios may change over time, and that the Board may augment the 
recession approach with certain salient risks, which would involve 
incorporating features that address aspects of the current economic or 
financial market environment that represent higher-than-normal risks to 
the condition of the banking system.
    In 2019, the Board updated the Scenario Design Policy Statement, 
which increased the transparency and predictability of the scenarios by 
allowing for a smaller-than-usual increase in unemployment if the 
stress test were to occur during an economic downturn, a change that 
would pass through to reduced severity of other key scenario variables 
due to the deference given to historical correlations. The 2019 update 
also introduced a formula with countercyclical features to guide the 
evolution of the ratio of housing prices to disposable income in the 
scenario, which provided more predictability in the way that the stress 
test would treat business lines affected by changes in house prices. 
However, the Board believes that the design of scenarios could be made 
more transparent and predictable by providing additional guides for 
certain macroeconomic variables, and by disclosing additional detailed 
information on the methodology used to create the global market shock 
component of the severely adverse scenario, as described below.
a. Trading and Counterparty Components
    For a subset of firms, the severely adverse scenario also includes 
two additional components: the global market shock component and the 
largest counterparty default component.\20\ The global market shock 
component is a set of hypothetical shocks to a large set of risk 
factors reflecting general market distress and heightened uncertainty. 
A firm with significant trading activity must consider the global 
market shock component as part of its severely adverse scenario and 
recognize associated losses in the first quarter of the projection 
horizon.\21\ The global

[[Page 51859]]

market shock component is applied to asset positions held by the firms 
on a given as-of date.\22\ In addition, for certain large and highly 
interconnected firms, the same global market shock component is applied 
to counterparty exposures under the largest counterparty default 
component.\23\ The largest counterparty default component is intended 
to assess the potential losses and capital impact associated with the 
default of the largest counterparty of each applicable firm, and the 
as-of date aligns with that of the global market shock component.
---------------------------------------------------------------------------

    \20\ See 12 CFR 238.143(b)(2)(i); 12 CFR 252.54(b)(2)(i). For 
more information on the scenarios and components, see Board, 2025 
Stress Test Scenarios (Feb. 2025), https://www.federalreserve.gov/publications/files/2025-stress-test-scenarios-20250205.pdf.
    \21\ The global market shock component applies to firms subject 
to Category I, II, and III standards that have aggregate trading 
assets and liabilities of $50 billion or more, or trading assets and 
liabilities equal to or greater than 10 percent of total 
consolidated assets. See 12 CFR 238.143(b)(2)(i); 12 CFR 
252.54(b)(2)(i).
    \22\ Under the Board's current stress test rules, the global 
market shock as-of date must occur between October 1 and March 1. 
See 12 CFR 238.143(b)(2)(i); 12 CFR 252.14(b)(2)(i); 12 CFR 
252.54(b)(2)(i).
    \23\ The largest counterparty default component generally 
applies to all firms subject to the global market shock component, 
as well as firms with substantial processing and custodial 
operations.
---------------------------------------------------------------------------

    The design and specification of the global market shock component 
differs from the design and specification of the severely adverse 
scenario in several respects. First, in alignment with U.S. generally 
accepted accounting principles (U.S. GAAP), profits and losses from 
trading and counterparty credit positions are measured in mark-to-
market accounting terms in the global market shock, while revenues and 
losses from traditional banking activities, as generated under 
macroeconomic scenarios, are generally measured using the accrual 
accounting method. Second, the timing of loss recognition differs 
between the global market shock and the severely adverse macroeconomic 
scenario. The global market shock affects the mark-to-market value of 
trading positions and counterparty credit losses in the first quarter 
of the severely adverse scenario. This timing is based on an 
observation that market dislocations can happen rapidly and 
unpredictably at any time under stressed conditions. In addition, the 
severely adverse scenario is applied as of December 31 of each year 
(the jump-off date), whereas the global market shock as-of date changes 
every year (within the window specified in the Board's stress test 
rules) and does not necessarily coincide with the year-end. This timing 
is also based on a scenario assumption that market dislocations can 
happen rapidly and unpredictably at any time during the scenario 
horizon. Recognizing the global market shock in the first quarter helps 
ensure that potential losses from trading and counterparty exposures 
are incorporated into firms' capital ratios in each quarter of the 
severely adverse scenario.
Models
    Prior to 2019, the annual stress test results disclosure document 
contained an appendix describing the Board's supervisory stress test 
models.\24\ In 2019, the Board increased the transparency of the 
supervisory stress test models by finalizing the Stress Testing Policy 
Statement \25\ and the Enhanced Disclosure of the Models Used in the 
Federal Reserve's Supervisory Stress Test (Enhanced Model 
Disclosure).\26\ The Stress Testing Policy Statement describes the 
Board's policies and procedures that guide the development, 
implementation, and validation of the models.\27\ The Stress Testing 
Policy Statement also describes the Board's principles for stress test 
model design, namely that the system of models used in the supervisory 
stress test should result in projections that are (1) independent of 
firm projections; (2) forward-looking in that they project future 
losses and revenue; (3) consistent and comparable across firms; (4) 
generated from simple approaches, where appropriate; (5) robust and 
stable; (6) conservative; and (7) able to capture the effect of severe 
economic stress. The Board has developed stress test models in 
accordance with these principles, which are the foundation for the 
stress test modeling decisions described in the comprehensive 
documentation of the supervisory stress test models that the Board is 
publishing in conjunction with this proposal.

    The Enhanced Model Disclosure supplemented prior public 
descriptions of the stress test models by providing some information 
about their structure and by including a list of key variables that 
influence the results of each model.\28\ However, the Board believes 
more detailed information, beyond what is in the current Enhanced Model 
Disclosure, would improve the ability of firms to accurately assess how 
changes in their business activities might impact their supervisory 
stress test results and, relatedly, their stress capital buffer 
requirements and overall capital requirements.

---------------------------------------------------------------------------

C. Supervisory Stress Test Modeling Framework

    The Board's stress test models take macroeconomic variables from 
the Board's severely adverse scenario and firm data as inputs to 
produce each firm's projected capital ratios over a nine-quarter 
horizon. The projected common equity tier 1 capital ratio is used to 
inform each firm's stress capital buffer requirement, which becomes 
part of a firm's capital conservation buffer.
    The stress test models are intended to capture how a firm's 
regulatory capital would be affected by the macroeconomic and financial 
conditions described in the stress test scenarios, given the 
characteristics of the firm's business model and balance sheet 
composition. The Board uses a variety of statistical modeling 
techniques to produce the stress test results, including multivariate 
regression, which uses relationships in historical data to produce 
projections of a variable (such as a loss given default). These models 
are represented by a set of formulas and coefficients that produce the 
projections.
    The Board estimates the effect of the severely adverse scenario on 
the regulatory capital ratios of firms by projecting revenues, 
expenses, and losses for each firm over a nine-quarter projection 
horizon (projection horizon). The projection horizon spans nine 
quarters to ensure that the firms can continue to provide credit and 
serve as financial intermediaries despite several quarters of adverse 
economic conditions, as well as to promote the forward-looking nature 
of capital planning by firms.
    Projected net income, adjusted for the effect of taxes, is combined 
with assumptions regarding capital actions and other changes to 
regulatory capital to produce post-stress capital ratios. The Board's 
approach to modeling supervisory stress test results, including the 
calculation of post-stress capital ratios, is generally in alignment 
with U.S. GAAP and the regulatory capital framework.\29\ However, the 
stress test models may deviate from U.S. GAAP and the regulatory 
capital framework, as circumstances warrant.
---------------------------------------------------------------------------

    \29\ See generally 12 CFR part 217.
---------------------------------------------------------------------------

    The Board established the Stress Testing Policy Statement modeling 
principles to ensure that the models are well suited for their purpose 
in the regulatory framework. In some cases, the Board's adherence to 
the principles limits modeling choices and results in certain common 
limitations across similarly constructed component

[[Page 51860]]

models. For instance, consistent with the principles of independence, 
consistency and comparability, and simplicity, models are not designed 
to capture all firm-specific nuances, future strategic initiatives, or 
planned capital actions. Additionally, models may be limited by their 
reliance on historic relationships and by the nature of the data 
captured in firms' regulatory reports. Detailed assumptions and 
limitations for the models are discussed in the comprehensive 
documentation, which is available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.
    Under the Stress Testing Policy Statement, the Board's projections 
also assume that a firm's balance sheet remains unchanged throughout 
the projection horizon.\30\ This assumption seeks to help ensure that a 
firm cannot ``shrink to health'' and that it remains sufficiently 
capitalized to accommodate credit demand in a severe downturn.
---------------------------------------------------------------------------

    \30\ See 12 CFR 252, Appendix B, section 2.7.
---------------------------------------------------------------------------

D. Stress Test Models

    The Board's stress test models comprise twenty-one component models 
that, when aggregated, produce projected regulatory capital ratios for 
each firm (see Table 1 below). The models can be grouped into four 
categories: credit risk, market risk, net revenue, and aggregation. 
Credit risk models capture losses associated with retail and wholesale 
loans that are held at amortized cost. Market risk models capture 
losses associated with trading and counterparty exposures, securities, 
and other assets held at fair value. Net revenue models capture income 
and expenses, including those related to operational risk, earned or 
incurred by a firm. Positive pre-provision net revenue offsets credit 
and market risk losses in the calculation of a firm's pre-tax net 
income. Aggregation models calculate a firm's pre-tax net income, which 
is then adjusted for other elements such as taxes and regulatory 
capital deductions to arrive at the projection of a firm's regulatory 
capital, which is used to calculate a firm's projected capital ratios. 
Additional detail about these component models is provided in Section 
III.A of this Supplementary Information and the comprehensive model 
documentation available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.\31\

E. Summary of the Proposal
---------------------------------------------------------------------------

    \32\ The Trading Issuer Default Loss Model, Trading Profit and 
Loss Model, Credit Valuation Adjustment Model, and Largest 
Counterparty Default Model apply only to a subset of firms. See 
Section II.B of this Supplementary Information.
---------------------------------------------------------------------------

    The Board is publishing comprehensive documentation on the stress 
test models on the Board's website, at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. This model documentation 
contains information on the models that together produce the results of 
the supervisory stress test. The model documentation includes the 
equations, variables, and coefficients used in each model (where 
applicable); assumptions and limitations of each model; rationales for 
modeling decisions; and discussions of alternative models. Section 
VIII.A of this Supplementary Information summarizes changes to the 
models, relative to the 2025 stress test, that the Board plans to 
implement in the 2026 stress test cycle; section VIII.B of this 
Supplementary Information contains an analysis of the potential effects 
of these proposed model changes. Detailed documentation on these 
changes is also provided on the Board's website, at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. As 
part of this proposal, the Board is inviting public comment on the 
stress test models and these changes.
    In addition, the Board is proposing to codify an enhanced 
disclosure process that would build on the previous efforts that the 
Board has made to increase the transparency and public accountability 
of the supervisory stress test. Under this enhanced disclosure process, 
the Board would annually publish comprehensive model documentation on 
the stress test models, invite public comment on any material changes 
that the Board seeks to make to those models, and annually publish the 
stress test scenarios for comment. The Board would also commit to 
responding to substantive public comments on any material model changes 
before implementing them. The proposal would revise the Stress Testing 
Policy Statement to align with this enhanced disclosure process, as 
well as to amend the Board's general policy related to disclosing 
additional information directly to a firm about that firm's supervisory 
stress test results. To accommodate the annual comment process on the 
scenarios, the proposal would shift the jump-off date of the 
supervisory and company-run stress tests from December 31 to September 
30.
    Additionally, this proposal would amend the Scenario Design Policy 
Statement in several ways. The Board would include in the Scenario 
Design Policy Statement detailed descriptions of additional guides that 
are used to inform the Board's choice of the values of the scenario 
variables along their scenario paths. The guides are designed to 
balance the competing objectives of predictability and transparency, on 
the one hand, with the severity and relevance of the macroeconomic and 
financial market scenarios, on the other hand. Most of the proposed 
guides also incorporate features similar to the range of options in the 
existing unemployment guide or the automatic adjustment of the house 
price path to current housing market conditions in the existing house 
price guide. This approach would allow the Board to continue to adjust 
the severity of those variables as necessary to avoid inducing greater 
procyclicality in the financial system and macroeconomy.
    Similarly, the Board is proposing to incorporate additional 
information into the Scenario Design Policy Statement about the 
framework used to create the global market shock component of the 
severely adverse scenario. This information includes, but is not 
limited to, details on the logic underlying the severity of the shocks 
and a description of the processes used to generate the shock values. 
The Board is also proposing to update the global market shock 
methodology to simplify the scenario and better align certain elements 
of the global market shock with the nature of an ``instantaneous'' 
shock. The proposal would also make revisions to the stress test rules 
to improve the risk capture of the supervisory stress test by widening 
the

[[Page 51863]]

as-of date window for the global market shock.
    Finally, the proposal would make changes to the FR Y-14A/Q/M 
reports to remove items and documentation requirements that are no 
longer needed to conduct the supervisory stress test, as well as to 
collect additional data to improve risk capture.

F. Purpose of the Proposal

    The purpose of this proposal is to provide the public with more 
information about the stress test models and scenarios and to help 
ensure that the public has an opportunity to comment on the models and 
scenarios. While the Board has increased the transparency of the stress 
test models over time, disclosing additional information about the 
stress test models and their underlying methodologies will further 
increase transparency and improve public accountability.
    Publishing detailed descriptions of the stress test models for 
comment, as well as committing to future enhanced disclosures, has 
benefits. First, the increase in transparency would increase public 
accountability and instill confidence in the fairness of the 
supervisory stress tests. Second, the disclosure process would create a 
new mechanism for obtaining feedback from the public, including 
academics, financial analysts, and firms, on the design and 
specifications of the models, which should lead to model improvements. 
Third, a firm would have a better sense of how its risk profile would 
factor into its stress capital buffer requirement, which would reduce 
the likelihood of unanticipated stress test results and allow for 
better capital and business planning by firms. Finally, the public 
disclosure of additional information about supervisory stress tests 
should strengthen market discipline, because investors, counterparties, 
and rating agencies would be able to better assess a firm's risk 
profile.\33\ The costs and benefits of this proposal are described more 
thoroughly in Section X of this Supplementary Information.
---------------------------------------------------------------------------

    \33\ See, e.g., N. Gambetta, M.A. Garc[iacute]a-Benau, & A. 
Zorio-Grima, Stress test impact and bank risk profile: Evidence from 
macro stress testing in Europe, 61 Intl. Rev. of Econ. & Fin 347-54 
(2019); I. Goldstein & Y. Leitner, ``Stress test disclosure: theory, 
practice, and new perspectives,'' Handbook of Financial Stress 
Testing 208-223 (2022).
---------------------------------------------------------------------------

    With respect to the proposed amendments to the Scenario Design 
Policy Statement, this proposal also builds on the contents of the 
current Scenario Design Policy Statement and would amend it to provide 
additional transparency, public accountability, and predictability in 
the variable paths. The changes would support the Board in developing 
scenarios, inviting comment on those scenarios, incorporating input 
from commenters, and maintaining the current schedule for release of 
the final scenarios. Despite the increased predictability in the 
scenarios, the new framework would remain flexible enough to suitably 
assess whether firms can maintain an adequate amount of loss-absorbing 
capital to stay above minimum regulatory requirements and continue 
financial intermediation during periods of stress, as well as adjust 
features that might add to existing procyclicality in the financial 
system, as appropriate. In practice, the scenarios resulting from the 
revised framework are expected to remain consistent with the current 
Scenario Design Policy Statement and should not result, on average over 
a typical business cycle, in materially different scenarios than would 
have been designed previously.
    Additionally, the proposal would simplify the design of the global 
market shock component and incorporate additional information on the 
development process into the Scenario Design Policy Statement, which 
outlines the Board's approaches to designing market shocks, including 
important considerations for scenario design, possible approaches to 
developing scenarios, and a development strategy for implementing the 
preferred approach. Taken together, these changes would improve 
transparency, public accountability, and predictability of the 
supervisory scenarios, while ensuring the supervisory stress test's 
ability to capture changes in the risks in the financial industry over 
time.

III. Overview of the Stress Test Modeling Framework

    As summarized in Section II.D of this Supplementary Information, 
the Board estimates the effect of the scenarios on the regulatory 
capital ratios of firms participating in the stress test by projecting 
net income and other components of regulatory capital for each firm 
over a nine-quarter projection horizon. To do so, the Board uses 
twenty-one component models, the macroeconomic variables from the 
Board's severely adverse scenario, and firm data. This section provides 
an overview of the component models the Board used to run the 2025 
supervisory stress test. See Table 1 in Section II.D of this 
Supplementary Information.

A. Supervisory Stress Test Models

    The Board calculates projected pre-tax net income by combining 
projections of pre-provision net revenue,\34\ provisions for credit 
losses,\35\ and other gains or losses.\36\ Each component of pre-tax 
net income is described below.
---------------------------------------------------------------------------

    \34\ Pre-provision net revenue includes, among other items, 
income from mortgage servicing rights, losses from operational risk 
events, and other real estate owned costs.
    \35\ For firms that have adopted Accounting Standards Update 
(ASU) 2016-13, the Federal Reserve incorporates its projection of 
expected credit losses on securities in the allowance for credit 
losses, in accordance with Financial Accounting Standards Board 
(FASB), Financial Instruments--Credit Losses (Topic 326). See FASB 
ASU No. 2016-13, ``Financial Instruments--Credit Losses (Topic 326): 
Measurement of Credit Losses on Financial Instruments.''
    \36\ Other gains or losses include losses on held-for-sale 
loans, loans measured under the fair-value option, and loan hedges.
---------------------------------------------------------------------------

Pre-Provision Net Revenue
    Pre-provision net revenue is defined as net interest income 
(interest income minus interest expense) plus noninterest income minus 
noninterest expense. Consistent with U.S. GAAP, these projections 
include projected losses due to operational risk events and expenses 
related to the disposition of other real estate owned.\37\ The Board 
projects most components of pre-provision net revenue using models that 
relate specific revenue and non-provision-related expenses to the 
characteristics of firms and to macroeconomic variables. These include 
eight components of interest income, seven components of interest 
expense, six components of noninterest income, and three components of 
noninterest expense. The Board separately projects losses from 
operational risk and other real estate owned expenses. Operational risk 
is defined as ``the risk of loss resulting from inadequate or failed 
internal processes, people and systems or from external events.'' \38\ 
Other real estate owned expenses are expenses related to the 
disposition of real estate owned properties and stem from losses on 
first-lien mortgages.
---------------------------------------------------------------------------

    \37\ However, pre-provision net revenue projections do not 
include debt valuation adjustments, which are not included in 
regulatory capital.
    \38\ 12 CFR 217.101 ``Operational risk.''
---------------------------------------------------------------------------

Loan Losses and Provisions on Loans Measured at Amortized Cost
    The Board typically projects losses using one of two modeling 
approaches: the expected-loss approach or the net charge-off approach. 
Generally, under the expected loss approach, expected losses are 
estimated by projecting the probability of default, loss given default, 
and exposure at default for each quarter of the projection horizon. 
Expected losses in each quarter are the product of these three 
components. Under the net

[[Page 51864]]

charge-off approach, losses are projected using historical behavior of 
net charge-offs as a function of macroeconomic and financial market 
conditions and loan portfolio characteristics.\39\
---------------------------------------------------------------------------

    \39\ Entire loans or portions of loans may be charged off if a 
firm believes that the loan will not be repaid. If an amount that is 
charged off is ultimately repaid by the borrower, then that repaid 
amount is added to a firm's income as a recovery. Net charge-offs 
are total charge-offs less any recoveries.
---------------------------------------------------------------------------

    The Board estimates losses for loans measured at amortized cost 
separately for different categories of loans, based on the type of 
obligor, collateral, and loan structure. The individual loan types 
modeled can broadly be divided into (1) retail loans, including various 
types of residential mortgages, credit cards, student loans, auto 
loans, small business loans, and other consumer loans; and (2) 
wholesale loans, such as commercial and industrial loans and commercial 
real estate loans. For most loan types, losses in quarter t are 
estimated as the product of the projected probability of default in 
quarter t, the loss given default in quarter t, and exposure at default 
in quarter t.
    The probability of default component measures the likelihood that a 
borrower enters default status during a given quarter t. The other two 
components capture the lender's net loss on the loan if the borrower 
enters default. The loss given default component measures the 
percentage of the loan balance that the lender will not be able to 
recover after the borrower enters default, and the exposure at default 
component measures the total expected outstanding loan balance at the 
time of default.\40\
---------------------------------------------------------------------------

    \40\ When applicable, loan loss models may factor in shared-loss 
agreements with the Federal Deposit Insurance Corporation.
---------------------------------------------------------------------------

    The Board's definition of default, for stress test modeling 
purposes, may vary for different types of loans and may differ from 
general industry definitions or classifications. The Board generally 
models probability of default as a function of loan characteristics and 
economic conditions. The Board typically models loss given default 
based on historical data, and modeling approaches vary for different 
types of loans. For certain loan types, the Board models loss given 
default as a function of borrower, collateral, or loan characteristics 
and the macroeconomic variables from the supervisory scenarios. For 
other loan types, the Board assumes loss given default is a fixed 
percentage of the loan balance for all loans in a category. The 
approach to modeling exposure at default also varies by loan type and 
depends on whether the loan is a term loan or a line of credit.
    For certain retail loan categories, projections capture the 
historical behavior of net charge-offs as a function of macroeconomic 
and financial market conditions and loan portfolio characteristics. The 
Board then uses these stress test models to project future charge-offs 
consistent with the evolution of macroeconomic conditions under the 
severely adverse scenario. To project losses, the projected net charge-
off rate is applied to projected loan balances.
    Losses on loans are then projected to flow into net income through 
provisions for loan and lease losses (for simplicity, provisions for 
loan losses). Provisions for loan losses reflect funds set aside to 
cover loan losses that a firm expects to incur in a predetermined 
future window. Provisions for loan losses feed into the allowance for 
loan losses, which serves as a contra asset on a firm's balance sheet. 
The charged-off amount of a loan reduces the outstanding balance of the 
loan while also reducing the allowance for loan losses (that is, 
charge-offs do not reduce a firm's total assets). Generally, provisions 
for loan losses for each projected quarter in the supervisory stress 
test equal projected losses on loans for the quarter plus the change in 
the allowance for loan losses needed to cover the subsequent four 
quarters of expected loan losses. This calculation incorporates the 
allowance for loan losses established by the firm as of the jump-off 
date of the stress test exercise.
Current Expected Credit Losses Framework
    On January 1, 2020, most large and mid-sized U.S. banks adopted the 
Current Expected Credit Losses (CECL) standard for calculating 
allowances.\41\ CECL superseded the incurred loss accounting standard, 
which was a backward-looking measure that enabled firms to calculate 
allowances based on historical loss data and current economic 
conditions. CECL, by contrast, is a forward-looking measure that 
requires firms to estimate lifetime losses based on reasonable 
estimates of future economic conditions. In October 2024, the Board 
announced that it would continue to evaluate future enhancements to the 
supervisory stress test approach for the incorporation of CECL.\42\
---------------------------------------------------------------------------

    \41\ See FASB ASU No. 2016-13, ``Financial Instruments--Credit 
Losses (Topic 326): Measurement of Credit Losses on Financial 
Instruments.''
    \42\ See Q(DST0030) (Oct. 9, 2024) and Q(DST0029) (Dec. 15, 
2023), https://www.federalreserve.gov/publications/ccar-qas/comprehensive-capital-analysis-and-review-questions-and-answers.htm.
---------------------------------------------------------------------------

    The Board is not proposing to implement CECL into the supervisory 
stress testing framework as a part of this proposal. The allowance 
calculation framework currently used in the supervisory stress test is 
already forward-looking: it projects loan loss provisions four quarters 
ahead. This approach aligns with the Board's modeling principle of 
simplicity as it requires fewer assumptions than would be required to 
determine provisions under CECL. In addition, in aggregate, the 
cumulative loan loss provisions under the supervisory severely adverse 
scenario are similar to provision projections submitted by the firms 
that have adopted CECL. Should the Board decide to implement CECL into 
the supervisory stress testing framework, it would seek public comment 
prior to implementation, as it would likely be a material model change 
as defined in this proposal.
    Question 2: What factors should the Board consider when determining 
whether to implement CECL into the supervisory stress testing framework 
and why?
    Question 3: What would be the advantages and disadvantages of 
incorporating CECL into the supervisory stress testing framework?
Losses on Loans Measured on a Fair Value Basis
    Certain loans are accounted for on a fair value basis instead of on 
an amortized cost basis. If a loan is accounted for using the fair 
value option, it is marked to market, and the accounting value of the 
loan changes as a function of changes in market risk factors and 
fundamentals. Similarly, loans that are held for sale are accounted for 
at the lower of cost or market value. The stress test models for these 
asset classes project gains and losses over the nine-quarter projection 
horizon, net of any hedges, using the scenario-specific path of 
interest rates and credit spreads. The Board uses different models to 
estimate gains and losses on wholesale loans and retail loans that are 
accounted for on a fair value basis since these loans have different 
risk characteristics. However, these models all generally project gains 
and losses over the nine-quarter projection horizon, net of hedges, by 
applying the scenario-specific interest rate and credit spread shocks 
to loan yields.
Losses on Securities
    A firm's balance sheet typically contains holdings of two types of 
securities related to investment activities: available-for-sale and 
held-to-

[[Page 51865]]

maturity. Available-for-sale and held-to-maturity securities are 
generally held at fair value and amortized cost, respectively, on a 
firm's balance sheet. The Board estimates two types of losses on 
securities related to investment activities.\43\
---------------------------------------------------------------------------

    \43\ This portfolio does not include securities held for 
trading. Losses on these securities are projected by the Trading 
Profit and Loss Model that projects gains and losses on trading 
exposures.
---------------------------------------------------------------------------

    For debt securities classified as available-for-sale, projected 
fluctuations in the fair value of the securities due to changes in 
interest rates and other factors will result in unrealized gains or 
losses that are recognized in capital for some firms through other 
comprehensive income. Under U.S. GAAP, unrealized gains and losses on 
available-for-sale debt securities are reflected in accumulated other 
comprehensive income and do not flow through net income.\44\ Under the 
regulatory capital rule, accumulated other comprehensive income must be 
incorporated into common equity tier 1 capital for certain firms. 
Unrealized gains and losses are calculated as the difference between 
each security's fair value and its amortized cost. The amortized cost 
of each available-for-sale debt security is equivalent to the purchase 
price of the debt security, which is periodically adjusted if the debt 
security was purchased at a price other than par or face value, has a 
principal repayment, or has an impairment recognized in earnings.\45\
---------------------------------------------------------------------------

    \44\ Unrealized gains and losses on equity securities are 
recognized in net income and affect regulatory capital for all 
firms. See FASB ASU No. 2016-01, ``Financial Instruments--Overall 
(Subtopic 825-10): Recognition and Measurement of Financial Assets 
and Financial Liabilities.''
    \45\ The fair value of each available-for-sale security is 
projected over the nine quarter projection horizon using either a 
present value calculation, a full revaluation using a security-
specific discounted cash flow model, or a duration-based approach, 
depending on the asset class.
---------------------------------------------------------------------------

    Credit losses on available-for-sale and held-to-maturity securities 
may be also recorded. Except for certain government-backed obligations, 
both available-for-sale and held-to-maturity securities are at risk of 
incurring credit losses.\46\ The stress test models project security-
level credit losses, using as an input the projected fair value for 
each security over the nine-quarter projection horizon under the 
severely adverse scenario. Credit losses on securities are included in 
the projection of provisions.
---------------------------------------------------------------------------

    \46\ Certain government-backed securities, such as U.S. 
Treasuries, U.S. government agency obligations, U.S. government 
agency or government-sponsored enterprise mortgage-backed 
securities, federally backed student loan asset-backed securities, 
and pre-refunded municipal bonds, are assumed not to be subject to 
credit losses.
---------------------------------------------------------------------------

    Projected other comprehensive income gains or losses from 
available-for-sale debt securities are computed directly from the 
projected change in fair value, taking into account credit losses and 
applicable interest-rate hedges on securities. All debt securities held 
in the available-for-sale portfolio are subject to other comprehensive 
income losses.
Losses on Private Equity Exposures
    The Board projects the value of private equity investments in 
response to the severely adverse scenario of the supervisory stress 
test.\47\ The Private Equity Model assigns losses and recoveries based 
on changes in fair value, recognized in net income for all positions, 
regardless of their individual accounting elections. While U.S. GAAP 
allows for private equity to be carried under a variety of accounting 
measures, the different accounting methods are generally not reflective 
of fundamental risk differences--fair value is typically realized upon 
the orderly sale of a given private equity investment, irrespective of 
its accounting treatment during the holding period.\48\
---------------------------------------------------------------------------

    \47\ The Board projects private equity losses only for firms 
that are required to submit FR Y-14Q, Schedule F.24 (Private Equity) 
because private equity exposures are reported on that schedule. 
Currently, Schedule F.24 is required to be reported by firms subject 
to Category I through III standards that have, on average, aggregate 
trading assets and liabilities of $50 billion or more, or aggregate 
trading assets and liabilities equal to 10 percent or more of total 
consolidated assets. As discussed in Section XI.A of this 
Supplementary Information, the Board is proposing to modify the 
threshold for Schedule F.24 to align with other banking book 
schedules.
    \48\ Unlike a bond or loan, private equity investments generally 
cannot be redeemed by holding to maturity and are therefore 
fundamentally exposed to market risk at exit.
---------------------------------------------------------------------------

Losses on Trading Exposures
    The trading stress test models cover a wide range of a firm's 
exposure to asset classes such as public equity, foreign exchange, 
interest rates, commodities, securitized products, traded credit (for 
example, municipal securities, auction rate securities, corporate 
credit, and sovereign credit), and other fair-value assets. Loss 
projections are constructed by applying the market risk factor 
movements specified in the global market shock component \49\ to market 
values of firm-provided positions and risk factor sensitivities.\50\ 
The global market shock only applies to a subset of firms, as described 
in Section II.B.a of this Supplementary Information. In addition, the 
global market shock component is applied to firm counterparty exposures 
to generate losses due to changes in credit valuation adjustment, which 
is a change to the market value of an exposure (for example, a 
derivative) to account for the risk that the counterparty defaults on 
its obligation. Trading and credit valuation adjustment losses are 
calculated only for firms subject to the global market shock component. 
In contrast to the nine-quarter evolution of losses for other parts of 
the supervisory stress test, and as previously described, these losses 
are estimated and applied in the first quarter of the projection 
horizon. This timing is based on the observation that market 
dislocations can happen rapidly and unpredictably any time under stress 
conditions. It also ensures that potential losses from trading and 
counterparty exposures are incorporated into a firm's capital ratio at 
all points in the projection horizon.
---------------------------------------------------------------------------

    \49\ See Section II.B.a of this Supplementary Information.
    \50\ The supervisory trading models are also used to calculate 
gains or losses on firms' portfolios of hedges on credit valuation 
adjustment exposures.
---------------------------------------------------------------------------

    The Board separately estimates the risk of losses arising from the 
default of issuers of debt securities held for trading. These losses 
account for concentration risk in corporate, sovereign, agency, and 
municipal credit positions. In contrast to the trading losses described 
above, these losses are applied in each of the nine quarters of the 
projection horizon to capture the risk that several quarters of 
stressful economic conditions may cause additional issuers of debt 
securities to default, which aligns with the Board's principle of 
conservatism from the Stress Testing Policy Statement.
Largest Counterparty Default Losses
    The largest counterparty default component is applied to firms with 
substantial trading or custodial operations. This component captures 
the risk of loss due to the unexpected default of the counterparty 
whose default on derivatives and securities financing transactions, 
with exposures revalued by applying the global market shock component, 
would generate the largest stressed losses for a firm. Consistent with 
the Board's modeling principles and with the losses associated with the 
global market shock component, losses associated with the largest 
counterparty default component are recognized in the first quarter of 
the projection horizon.
Balance Projections and the Calculation of Regulatory Capital Ratios
    As described above, the Board assumes that a firm takes actions to 
maintain its current level of assets, including its investment 
securities, trading assets, and loans, over the

[[Page 51866]]

projection horizon. The Board also assumes that a firm's risk-weighted 
assets and leverage ratio denominators remain unchanged over the 
projection horizon, except that the Board will account for changes 
primarily related to the calculation of regulatory capital or due to 
changes to the Board's regulations.\51\
---------------------------------------------------------------------------

    \51\ See 12 CFR 252, Appendix B, section 3.4; Board, Press 
Release (Mar. 4, 2020), https://www.federalreserve.gov/newsevents/pressreleases/bcreg20200304a.htm.
---------------------------------------------------------------------------

    The Board includes five regulatory capital ratios in the 
supervisory stress test: (1) common equity tier 1 risk-based capital, 
(2) tier 1 risk-based capital, (3) total risk-based capital, (4) tier 1 
leverage, and (5) supplementary leverage. A firm's post-stress 
regulatory capital ratios are projected in accordance with the Board's 
regulatory capital rule using the Board's projections of pre-tax net 
income and other scenario-dependent components of the regulatory 
capital ratios. Pre-tax net income and the other scenario-dependent 
components of the regulatory capital ratios are combined with 
additional information, including assumptions about taxes and capital 
distributions, to project post-stress measures of regulatory capital. 
In those calculations, the Board adjusts pre-tax net income to account 
for taxes and other components of net income, such as income 
attributable to minority interests, to arrive at after-tax net income. 
The Board calculates the change in equity capital over the projection 
horizon by combining projected after-tax net income with changes in 
other comprehensive income, assumed capital distributions, and other 
components of equity capital. The path of regulatory capital measures 
over the projection horizon is calculated by combining the projected 
change in equity capital with the firm's starting capital position and 
accounting for other adjustments to regulatory capital specified in the 
Board's regulatory capital framework.\52\ The denominator of each 
firm's risk-based capital ratios is based on a firm's standardized 
approach for calculating risk-weighted assets on the jump-off date of 
the supervisory stress test, and may change for each quarter of the 
projection horizon to account for adjustments specified in the capital 
rule (for example, adjustments due to the thresholds for deducting 
certain deferred tax assets).
---------------------------------------------------------------------------

    \52\ The regulatory capital framework specifies that regulatory 
capital ratios account for items subject to adjustment or deduction 
in regulatory capital, limits the recognition of certain assets that 
are less loss-absorbing, and imposes other restrictions. See 
generally 12 CFR part 217.
---------------------------------------------------------------------------

B. Supervisory Stress Test Scenarios

    The Board conducts the supervisory stress test using two 
scenarios--the baseline and severely adverse. The severely adverse 
scenario describes a hypothetical set of conditions designed to assess 
the strength and resilience of firms in a severely adverse economic 
environment and includes 28 variables that are disclosed by the Board 
each year prior to the supervisory stress test. Some variables describe 
economic developments within the United States while others describe 
developments in foreign countries.\53\ These variables serve as an 
input to the calculation of supervisory stress test results for all 
firms. As discussed above, for a subset of firms, the severely adverse 
scenario also includes two additional components: the global market 
shock component and the largest counterparty default component. The 
scenarios and associated components are developed solely for 
supervisory stress testing purposes and do not represent economic 
forecasts of the Board.
---------------------------------------------------------------------------

    \53\ For a description of the macroeconomic variables applicable 
to the 2025 supervisory stress test, see Board, 2025 Stress Test 
Scenarios (Feb. 2025), https://www.federalreserve.gov/publications/files/2025-stress-test-scenarios-20250205.pdf.
---------------------------------------------------------------------------

Geographic Variation of Macroeconomic Variables
    While the Board projects the paths of macroeconomic variables at 
the national level, the Board uses regional-level (that is, state- and/
or county-level) macroeconomic variables in the stress test models to 
project losses on certain loans held for investment at amortized 
cost.\54\ In general, model outputs are demonstrably impacted by the 
macroeconomic environment, as both probability of default and loss 
given default increase during periods of economic stress. Importantly, 
the macroeconomic environment can also vary notably across geography, 
in addition to across time. For instance, during the 2007-2009 crisis 
period, housing prices fell more sharply in certain geographies 
compared to others. Accordingly, historical loss rates in many loan 
categories were higher during this period in geographies where housing 
prices fell more sharply.
---------------------------------------------------------------------------

    \54\ Specifically, the Board uses regional-level macroeconomic 
variables in the First Lien Model, the Home Equity Model, the Credit 
Card Model, the Auto Model, and the Commercial Real Estate Model.
---------------------------------------------------------------------------

    Therefore, to account for the impacts of different macroeconomic 
environments across geographies on historical loan performance, the 
Board calibrates model parameters in certain stress test models using 
regional macroeconomic variables as opposed to national macroeconomic 
variables. For example, the unemployment rate used in an applicable 
model may be the state level unemployment rate, while the house price 
index values used in the model may be the county-level house price 
indices or, in the case of loans in counties where a house price index 
is not projected, a state-level house price index.\55\ Analysis 
performed by the Board demonstrates that a certain model's statistical 
fit and sensitivity to the macroeconomic environment may perform better 
when using regional-level variables compared to when using only 
national-level variables. The use of regional-level variables is 
described in each applicable model section of the comprehensive model 
documentation.
---------------------------------------------------------------------------

    \55\ Certain variables do not vary based on geography. For 
example, interest rates are typically set by national and not 
regional markets. For these variables, the Board uses the national-
level paths in the models.
---------------------------------------------------------------------------

    However, because the severely adverse scenario only includes 
national-level variable paths, the Board derives the paths of regional-
level variables from the paths of national-level variables. The Board 
employs a simple approach to calculating the paths of regional-level 
variables in that these variables have the same percentage change (in 
the case of an index variable) or level change (in the case of non-
index variables) as the national-level variables, but the starting 
points are the regional-level values, not the national-level values. 
For example, the projected path of the house price index is assumed to 
have the same percentage change in a given quarter as the percentage 
change of the national house price index,\56\ and the projected path of 
unemployment rate is assumed to have the same level change in a given 
quarter as the level change of the national unemployment rate.\57\ The 
use of percentage changes for home price indices and level changes for 
unemployment rates avoids accentuating differences in the macroeconomic 
environment observed immediately prior to the beginning of the 
scenario, which could lead to large discrepancies in projected variable 
paths across geographies during the severely adverse scenario.
---------------------------------------------------------------------------

    \56\ The house price index used in the supervisory stress test 
scenarios is set to be equal to 100 in January 2000. This choice of 
index month is arbitrary and does not reflect any underlying 
economic importance of this period.
    \57\ For example, if the national unemployment rate increases by 
0.5 percentage points in a given quarter, the state-level 
unemployment rate would be projected to increase by 0.5 percentage 
points in that quarter as well.
---------------------------------------------------------------------------

    These simple, uniform policies for allocating changes to the 
national

[[Page 51867]]

macroeconomic environment at the regional level ensure that loans to 
borrowers in certain geographies are not unduly favored or penalized. 
While it is plausible that certain geographies may experience more 
volatility than others in terms of the macroeconomic environment, the 
Board does not estimate such volatility to differentiate scenarios 
across geography, to avoid making assumptions about the severity of a 
hypothetical recession across different regions.
    The Board also uses historical regional data to produce model 
projections. While the regional scenarios are projected based on the 
national path, the Board retains variation in the historical regional 
macroeconomic variables.\58\ The Board may also use historical regional 
macroeconomic variables in the models to calculate the appreciation in 
house prices since origination (which may be needed to calculate loan-
to-value ratios), or the Board may use regional macroeconomic variables 
to calculate year-over-year changes in the variables. Alternatively, 
the Board could replace all historical values with their national 
equivalent when projecting losses, thus applying a truly uniform 
treatment across geographies. While this alternative would have the 
benefit of maximizing geographic consistency, it would ignore 
meaningful variation in the historical environment and thereby reduce 
the predictive power of the model. For instance, if a given geography 
has had higher house price appreciation since its origination date 
compared to the national average, without incorporating these 
historical values into the macroeconomic data used to project losses 
the model would understate the level of equity the borrower has as of 
the beginning of the projection period. The Board has therefore 
developed this hybrid approach to estimating losses in the supervisory 
stress test, in which it applies a uniform treatment to projected 
values of macroeconomic variables across geographies, while also 
retaining historical differences across geographies. This methodology 
allows for the incorporation of all available historical data needed to 
produce accurate projections, while avoiding the need to make 
assumptions about which geographies will have more or less severe 
macroeconomic paths during a hypothetical recession. Further discussion 
of how the Board's models account for geographic variation in 
variables, including a proposed change to the Board's modeling 
approach, is included in the comprehensive model documentation, 
available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.
---------------------------------------------------------------------------

    \58\ The historical regional unemployment rate and house price 
index data are seasonally adjusted using the X11 procedure when a 
seasonally adjusted version of these series is not available from 
the source data. Seasonal adjustment is applied for consistency and 
comparability with the published national scenario variables. For 
more information about the X11 procedure developed by the U.S. 
Census Bureau, see Shiskin J., Young A., and Musgrave, J., 1967. The 
X-11 Variant of the Census Method II Seasonal Adjustment Program. 
U.S. Department of Commerce, Bureau of the Census.
---------------------------------------------------------------------------

    Question 4: What are the advantages and disadvantages of the 
Board's treatment of regional (i.e., state and county) macroeconomic 
variables in the credit risk models?
    Question 5: What alternatives should the Board consider to the 
approach outlined above for defining state and county macroeconomic 
variables based on the national variables included in the scenarios? 
What would be the advantages and disadvantages of these alternatives?
Auxiliary Variables
    In addition to the 28 variables that the Board discloses each year, 
the Board also generates paths for a limited number of other variables 
that are used in the supervisory stress test. These variables, known as 
auxiliary variables, are not disclosed by the Board because their paths 
are based on the paths of the 28 disclosed variables (that is, the 
paths are contingent upon movements in the 28 disclosed variables). For 
example, the path of Mexico's gross domestic product (GDP) growth rate 
is a function of the GDP growth rate paths of other country blocs that 
are disclosed. Some models use these auxiliary variables, as described 
in the applicable model sections of the comprehensive model 
documentation available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.\59\
---------------------------------------------------------------------------

    \59\ Detailed descriptions of the process for creating the paths 
of auxiliary variables are included in the applicable model 
documentation.
---------------------------------------------------------------------------

C. Data Used in Stress Testing

Input Data
    The Board generally develops and implements the models with data it 
collects on regulatory reports as well as proprietary third-party 
industry data. Most of the data used in the supervisory stress test 
projections are collected through the Capital Assessments and Stress 
Testing regulatory report (FR Y-14), which includes a set of annual (FR 
Y-14A), quarterly (FRY-14Q), and monthly (FRY-14M) schedules.\60\
---------------------------------------------------------------------------

    \60\ The FR Y-14 report forms and instructions are available on 
the Board's website at https://www.federalreserve.gov/apps/reportforms/default.aspx.
---------------------------------------------------------------------------

    A firm must submit detailed loan and securities information for all 
material portfolios on the FR Y-14Q and FR Y-14M. The definition of a 
material portfolio for purposes of FR Y-14 reporting is based on a 
firm's size and complexity.\61\ Portfolio categories are defined in the 
FR Y-14M and FR Y-14Q reporting instructions. Each firm has the option 
to submit the relevant data schedule for a given portfolio that does 
not meet the materiality threshold as defined in the instructions. If a 
firm does not submit data on its immaterial portfolio(s), the Board 
will assign to that portfolio the median loss rate estimated across the 
set of firms with material portfolios. This loss assumption adheres to 
the principle of simplicity, as well as the principle of consistency 
and comparability, from the Stress Testing Policy Statement.
---------------------------------------------------------------------------

    \61\ Specifically, the definition of a material portfolio varies 
depending upon a firm's categorization in the risk-based category 
framework adopted by the Board for determining prudential standards. 
See 12 CFR 238.10; 12 CFR 252.5.
---------------------------------------------------------------------------

    While each firm is responsible for ensuring the completeness and 
accuracy of data provided in the FR Y-14 reports, the Board makes 
efforts to validate firm-reported data and requests resubmissions of 
data where errors are identified. If data quality remains deficient 
after resubmission, the Board applies conservative assumptions to a 
particular portfolio or to specific data, depending on the severity of 
deficiencies. For example, if the Board deems the quality of a firm's 
submitted data too deficient to produce a stress test model estimate 
for a particular portfolio, then the Board assigns a high loss rate 
(for example, 90th percentile) or a conservative pre-provision net 
revenue rate (for example, 10th percentile) to the portfolio balances 
based on supervisory stress test projections of portfolio losses or 
pre-provision net revenue for other firms.\62\ If data that are direct 
inputs to stress test models are missing or reported erroneously but 
the problem is isolated in such a way that the existing supervisory 
framework can still be used, the Board assigns a conservative value 
(for example, 10th or 90th percentile) to the specific data based on 
all available data reported by firms. These assumptions are consistent 
with the Board's principle of conservatism and policies on the 
treatment of immaterial portfolios and missing or erroneous

[[Page 51868]]

data, as described in the Stress Testing Policy Statement.
---------------------------------------------------------------------------

    \62\ Prior to assigning a conservate loss or revenue rate to 
produce a firm's stress test results, the Board consults with a firm 
that submits deficient data in order to determine whether the 
applicable data issue can be remedied.
---------------------------------------------------------------------------

    Additionally, certain stress test model projections rely on data 
from the Consolidated Financial Statements for Holding Companies 
regulatory report (FR Y-9C), which contains consolidated income 
statement and balance sheet information for each firm subject to the 
stress test. The FR Y-9C also includes off-balance sheet items and 
other supporting schedules, such as the components of risk-weighted 
assets and regulatory capital, that may be used in the stress test 
models.
    In limited circumstances, the Board also uses data provided by 
third parties in the development and execution of the supervisory 
stress test. The comprehensive model documentation identifies these 
instances. The scenario data discussed above is also an input into the 
stress test projections.
Data Preparation and Adjustments
a. Data Preparation
    The data inputs the Board uses may not be initially suitable for 
use in the stress test models. In these cases, the Board takes several 
steps to prepare the data for use in the stress test models. The 
specific steps for each model are discussed in the applicable model 
descriptions within the comprehensive model documentation, though 
generally data are prepared for use in the models for two purposes: to 
remove outliers from the sample and to seasonally adjust the data. 
These adjustments help ensure that the model results are reasonable.
    The Board may remove outliers or data that are not applicable to 
the model from the sample to facilitate more usable results. For 
example, if a commercial real estate loan has a unusually high loan-to-
value (LTV) ratio (over 150 percent at origination), then data for that 
loan are not included in the Commercial Real Estate Model because its 
inclusion may produce unreliable results. Additionally, if first lien 
mortgages are insured by the Federal Housing Administration or 
Department of Veterans Affairs, then they are excluded from the First 
Lien Model because these loans would not generate losses in the 
supervisory stress test, as they are assumed to be fully insured by the 
U.S. government. In both examples, the model output is more sensible 
and more reflective of a firm's risk profile because of these 
adjustments.
    The Board also may seasonally adjust data, where appropriate. For 
example, the vacancy rate of hotel commercial real estate exposures may 
fluctuate on a seasonal cycle, with the vacancy rate moving higher or 
lower in certain months based on a somewhat predictable pattern. 
Because the vacancy rate can be an important variable for calculating 
losses on hotel commercial real estate loans, this rate is seasonally 
adjusted to ensure that the Commercial Real Estate Model produces more 
stable results.
    These types of data preparation steps help ensure that the Board's 
models produce more reasonable results and that they align with the 
principles in the Stress Testing Policy Statement in that they generate 
consistent and robust projections. The Board therefore expects to 
continue to use these data preparation steps, where appropriate, as 
they are integral to the supervisory stress test process.
b. Data Adjustments
    Data inputs are integral to generating the output of the stress 
test models, which is a key component of a firm's stress capital buffer 
requirement. The Board's Stress Testing Policy Statement notes that the 
Board does not use data submitted by one or some of the firms unless 
comparable data can be collected from all the firms that have material 
exposure in a given area when generating supervisory stress test 
projections.\63\ However, situations may arise where adjustments to a 
firm's data would make the results more reasonable, and therefore 
better calibrate a firm's stress capital buffer requirement to its risk 
profile. The Board expects to continue to make these adjustments going 
forward, where appropriate. Examples of when the Board may apply these 
adjustments are described below.
---------------------------------------------------------------------------

    \63\ See 12 CFR 252, Appendix B, section 2.8.
---------------------------------------------------------------------------

    For example, the Board may apply a data adjustment where there is 
missing or deficient firm-provided data, or where a firm uses 
divestiture accounting. As described above, if the Board deems the 
quality of a firm's submitted data too deficient to produce a stress 
test model estimate for a particular portfolio, then the Board assigns 
a conservative loss rate (for example, 90th percentile) or a 
conservative pre-provision net revenue rate (for example, 10th 
percentile) to the portfolio balances based on supervisory stress test 
projections of portfolio losses or pre-provision net revenue for other 
firms. If data that are direct inputs to stress test models are missing 
or reported erroneously but the problem is isolated in such a way that 
the existing supervisory framework can still be used, the Board assigns 
a conservative value to the specific data based on all available data 
reported by firms.
    Additionally, when a firm sells assets or businesses, it may use 
divestiture accounting in its financial statements until the sale is 
consummated. Under divestiture accounting, a firm may list divested 
assets as discontinued operations, classify them as held for sale or 
available for sale instead of held for investment or held to maturity, 
and report revenues as income from discontinued operations. The 
accounting classification can be important for the supervisory stress 
test as it may determine which model stresses the assets or income. For 
example, in the 2025 supervisory stress test, the Board adjusted 
certain input data that had been reclassified due to divestiture 
accounting to improve projections of loan losses and related income to 
ensure consistent treatment across firms with similar risks.

IV. Enhanced Disclosure Process

    The Board is proposing to codify an enhanced disclosure process 
under which the Board would annually publish comprehensive 
documentation on the stress test models, invite public comment on any 
material changes that the Board seeks to make to those models, and 
annually publish the stress test scenarios for comment.

A. Annual Disclosure of Models

    Under the proposal, the Board would annually publish comprehensive 
documentation on the stress test models, similar to the comprehensive 
documentation the Board is publishing with this proposal at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. The 
Board would be required to publish this comprehensive documentation by 
May 15 of the year in which the stress test is performed, and the 
models described in the documentation would be used to produce the 
stress test results disclosed by the Board by June 30 of that year. In 
addition, the Board would seek public comment, and respond to such 
public comment, on any material changes to the models before 
implementing those changes in a stress test. Material model changes are 
discussed in more detail in Section IV.B of this Supplementary 
Information. To implement this enhanced disclosure process, the Board 
is proposing to revise Regulations YY and LL, as well as the Stress 
Testing Policy Statement.
    For example, if the Board did not seek to make any material model 
changes to its stress test models for the 2027 supervisory stress test, 
then it would publish the comprehensive model documentation used in the 
2027 stress test cycle by May 15, 2027. This

[[Page 51869]]

documentation would identify any changes (relative to the models used 
in the 2026 stress test), including technical, non-material changes to 
the models to improve performance. This process would allow the public 
to review the changes, as well as comprehensive documentation on the 
models used in the 2027 stress test cycle, before the release of the 
stress test results.
    As an alternative example, if the Board sought to implement a 
material model change (as discussed in Section IV.B of this 
Supplementary Information) in the 2027 supervisory stress test, then 
the Board would seek comment on the proposed change, consider and 
respond to public feedback, and, then implement, defer, or reject the 
material model change for the 2027 stress test cycle. If the Board 
sought to implement the material model change in the 2027 stress test, 
the Board would republish updated model documentation before or 
simultaneously with the annual publication of comprehensive model 
documentation (i.e., by May 15, 2027). This process for material model 
changes would increase the transparency of the Board's stress testing 
model framework and ensure that the public has the opportunity to 
comment on material model changes before they are used in the next 
stress test cycle.
    Question 6: How else could the Board enhance the transparency and 
public accountability of its stress test models? For instance, what 
additional information regarding the stress test models, if any, should 
the Board provide, and why?
    Question 7: How else could the Board facilitate public 
participation in model development? For example, the Board could invite 
comment on all model changes, rather than only material model changes, 
before implementing them in the stress test. Under such an approach, 
the Board could make an exception for technical or other types of 
ministerial changes. Such a process would limit the Board's flexibility 
to revise models due to unforeseen events and circumstances. What are 
the advantages and disadvantages of this expanded approach or other 
approaches to facilitate public participation in model development? How 
should the Board balance transparency and public accountability with 
model dynamism and operational burden?
    Question 8: What are the advantages and disadvantages of inviting 
public comment, and committing to responding to comments, on material 
model changes before the Board implements them in the subsequent stress 
test?
    Question 9: What are the advantages and disadvantages of publishing 
the comprehensive model documentation by May 15 of each stress test 
cycle? For example, does this timeline provide enough time for the 
public to review any changes made by the Board to confirm they are not 
material? Should the Board consider publishing the comprehensive model 
documentation earlier at an earlier date, such as April 5, or a later 
date, such as June 30? What would be the advantages or disadvantages of 
publishing the comprehensive model documentation earlier or later?
    Question 10: The Board is not currently publishing the results of 
its internal model validation process. What would be the advantages and 
disadvantages of publishing these results or providing more information 
about its internal model validation process?

B. Model Changes

    The proposed rule would define a ``model change'' to mean ``the 
introduction of a new model or a conceptual change to an existing 
model.'' \64\ Conceptual changes to existing models would include 
changes to model assumptions, incorporation of a new statistical 
technique to estimate loss, or the addition or deletion of any model 
components or sub-components that currently inform a firm's stress 
capital buffer requirement.
---------------------------------------------------------------------------

    \64\ As discussed in Section II.D of this Supplementary 
Information, there are twenty-one component models that comprise the 
stress test models. A ``new model'' would mean a model that fully 
replaces one of these twenty-one component models or is added to the 
modeling suite (e.g., a 22nd component model). For purposes of 
assessing materiality, as discussed in Section IV.C of this 
Supplementary Information, model changes would not be aggregated or 
netted across the component models.
---------------------------------------------------------------------------

    Model changes would not include changes resulting from updates or 
adjustments to input data, such as firm data, third-party vendor data, 
and scenario data, including any re-estimation based on this data, as 
well as changes related to the mechanical implementation of federal, 
state, or local laws that are directly embedded in a stress test model 
(e.g., the federal statutory tax rate).\65\ As is current practice, the 
Board would continue to implement model changes related to changes in 
accounting definitions or regulatory capital rules and model parameter 
re-estimation based on newly available data with immediate effect. 
These types of adjustments would not be considered model changes since 
they do not substantively change the form of the stress test models as 
described in the documentation. For example, the Board re-estimates 
many of its models with updated data each year when it runs the 
supervisory stress test. This re-estimation may result in changes to 
the statistical coefficients produced by some of the models, even 
though the Board has made no conceptual changes to the models. Under 
the proposed definition of model change, such re-estimation would not 
be viewed as a model change because the resulting changes stem solely 
from updated data and not from a conceptual change to the models. In 
contrast, the introduction or revision of a legal requirement that 
causes a conceptual change to a model could be considered a model 
change, and the Board would seek public comment before implementing 
such a change if it met the proposed definition of a material model 
change.
---------------------------------------------------------------------------

    \65\ Re-estimation comprises updates to model parameters based 
on consideration of different input data (e.g., incorporating the 
most recent year's data as a model input, or incorporating data from 
new stress test entrants or from mergers).
---------------------------------------------------------------------------

    Question 11: What other types of changes to the supervisory stress 
testing framework could the Board consider including in the definition 
of ``model change''? What are the advantages and disadvantages of 
broadening or narrowing the definition of ``model change''? For 
example, should the Board define ``model changes'' to include changes 
that result from new or updated input data, or changes that result from 
using a new, third-party data source?

C. Material Model Changes

    Each year, the Board refines and enhances its stress test models to 
reflect advances in modeling techniques, respond to model validation 
findings, incorporate richer and more detailed data, or identify more 
stable models or models with improved performance, particularly under 
stressful economic conditions. These changes may include re-
specification of models based on performance testing, benchmarking, and 
other targeted changes used to produce projections.\66\ This process is 
an important aspect of the modeling framework to help ensure that the 
stress test models capture changes in borrower and lender behavior and 
bank business practices. These model changes also help ensure that the 
models are able to remain dynamic (i.e., can be enhanced to capture 
emerging risks), produce

[[Page 51870]]

reasonable results, identify salient risks at firms, and maintain an 
optimal level of robustness and stability.
---------------------------------------------------------------------------

    \66\ Benchmarking is the process of evaluating a model's 
performance by comparing its outputs and other performance metrics 
against a specific standard, baseline, or the output and performance 
of other comparable models or relevant data sources.
---------------------------------------------------------------------------

    In addition, the Board must sometimes make changes to its stress 
test models while it is running the stress test in response to 
unforeseen events or circumstances to ensure that model output is 
reasonable. For example, during the COVID-19 pandemic, the vacancy 
rates for hotel properties were unprecedented and the Board made 
certain adjustments to yield sensible commercial real estate loan 
losses in the model output. Without making these in-cycle changes, the 
results of the stress test would have been irrational and led to stress 
capital buffer requirements that were not commensurate with applicable 
firms' risk profile.
    Under the proposed enhanced disclosure process, if these changes 
are not material, as defined below, the Board would publish these model 
changes by May 15 of the year in which the stress test is performed. To 
balance the benefit of public feedback with the operational and 
resource costs of seeking such feedback and to allow the Board to make 
timely model adjustments to ensure reasonable results, the Board would 
not formally invite public comment on these non-material model changes 
before implementing them in the stress test; however, the Board 
welcomes public feedback on these and all other aspects of the stress 
test models once they are published. Notably, the Board would not 
implement any in-cycle adjustments that are considered material model 
changes prior to seeking public comment on the adjustment. In addition, 
the Board would review and respond to all substantive public comments 
on material model changes before implementing them in the stress test.
    As discussed above, the Board is proposing to publish for comment 
all material model changes and respond to all substantive comments on 
such material model changes before implementing them in the stress 
test. For example, if the Board sought to implement a new statistical 
technique that would result in a material model change, then the Board 
would seek public comment prior to implementing either of those 
changes.\67\ The Board is proposing to define a ``material model 
change'' as a model change that could have, in the Board's estimation, 
an impact on the post-stress common equity tier 1 capital ratio of any 
firm, or on the average post-stress common equity tier 1 capital ratios 
of all firms required to participate in the upcoming stress test cycle, 
based on the prior year's severely adverse scenario and prior year's 
input data, equal to (i) a change of 20 basis points or more in the 
projected common equity tier 1 ratio of any firm participating in the 
upcoming stress test cycle; or (ii) a change of 10 basis points or more 
in the average of the absolute value of each firm's change in projected 
common equity tier 1 ratio.\68\ The Board proposes to apply this 
definition of a material model change across both Regulation YY and 
Regulation LL, such that the individual materiality threshold would 
apply to all firms required to participate in the next stress test 
under either regulation, and such that the Board's estimation of 
whether a change meets the aggregate materiality threshold would be 
determined across all firms required to participate in the next stress 
test under either regulation.
---------------------------------------------------------------------------

    \67\ For purposes of assessing materiality, model changes would 
not be aggregated or netted across the component models. For 
example, if the Board proposed a change to both the Pre-Provision 
Net Revenue Model and Corporate Model in the same stress test cycle, 
the Board would estimate the effects of each change separately for 
purposes of determining materiality. Similarly, for purposes of 
assessing materiality, model changes would not be aggregated or 
netted within component models. For example, if the Board proposed 
two changes to a component model, the Board would evaluate the 
materiality of each change separately.
    \68\ The Board would take the absolute value of each firm's 
change in projected common equity tier 1 ratio, then average those 
values. If the average is 10 basis points or greater, the change 
would constitute a material model change.
---------------------------------------------------------------------------

    The Board is proposing to use the threshold of a 20 basis point 
change in the common equity tier 1 capital ratio for individual firms 
in the definition of material model change because that threshold would 
ensure that the public would be able to comment on any change that 
would be likely to affect a firm's stress capital buffer requirement. 
Considering the history of recent model changes, a threshold of 20 
basis points would generally capture model changes that involve 
conceptual enhancements to model specifications, such as to incorporate 
improved modeling techniques or to capture emerging risks, while 
scoping out those that are simpler model refinements, such as those 
implemented to ensure that the models maintain consistency given 
changing requirements (e.g., refinements made to accommodate the 
transition from the London Interbank Offered Rate to SOFR). Therefore, 
changes of smaller magnitudes would be unlikely to impact a firm's 
stress capital buffer requirement, particularly if the proposed two-
year averaging approach to calculate a firm's stress capital buffer 
requirement is adopted.\69\ If the two-year averaging approach is not 
finalized or not finalized as proposed, the Board would consider a 
lower individual materiality threshold of 10 basis points, which would 
ensure that the public would be able to comment on any change that 
would be likely to affect a firm's stress capital buffer requirement 
without two-year averaging.
---------------------------------------------------------------------------

    \69\ See 90 FR 16843 (Apr. 22, 2025).
---------------------------------------------------------------------------

    The Board is proposing the threshold of a 10 basis point average 
change in the absolute value of the change to each firm's projected 
common equity tier 1 capital ratio in case a model change has minimal 
individual impacts, but has a notable aggregate impact on firms 
required to participate in the upcoming stress test. The Board selected 
10 basis points for this aggregate prong because a model change of this 
size would be likely to impact the aggregate projected common equity 
tier 1 capital ratio, which is a salient measure of the health of the 
banking system. A change that satisfies either of these materiality 
thresholds would be considered a material model change.
    Question 12: What are the advantages and disadvantages of this 
definition of a material model change? What alternative quantitative 
thresholds for materiality, if any, should the Board consider, and why? 
For example, in assessing the materiality of a model change, as 
described in the Stress Testing Policy Statement, the Federal Reserve 
currently considers a change to be highly material if it would result 
in a change in the common equity tier 1 capital ratio of 50 basis 
points or more for one or more firms, relative to the model used in 
prior years' supervisory exercises. What would be the advantages and 
disadvantages of this or other alternative standards?
    Question 13: What alternative definitions of materiality, if any, 
should the Board consider? For example, the Board could consider the 
impact of a change on a firm's pre-tax net income, rather than its 
common equity tier 1 ratio. What are the advantages and disadvantages 
of such alternative definitions?
    Question 14: Under the proposal, for purposes of assessing the 
materiality of a model change, the Board would not aggregate or net the 
impact across or within component models. What forms of netting or 
aggregation, if any, would be most appropriate and why? What would be 
the advantages and disadvantages of netting or aggregating model 
changes across or within component models to assess materiality? If the 
Board were to net or

[[Page 51871]]

aggregate model changes, should the Board consider alternative 
materiality thresholds? For example, the Board could consider an 
alternative definition of materiality that considers the aggregate 
impact of all of the model changes the Board intends to implement in a 
future stress test cycle. Alternatively, the Board could aggregate the 
impacts of all model changes to a given suite of models (e.g., credit 
risk models) instead of considering the individual impacts of model 
changes to the Auto Loan Model and the Commercial Real Estate Model.
    Question 15: What are the advantages and disadvantages of inviting 
and responding to public comment on material model changes before 
implementing those changes? The proposal does not currently specify the 
length of the comment period. What are the advantages and disadvantages 
of a set length for the comment period (e.g., 30-day, 60-day, etc.)? 
When considering the appropriate length of the comment period, how 
should the Board evaluate trade-offs, for instance, between ensuring 
that the public has ample time to consider and comment on material 
model changes and ensuring that the stress test results are released by 
June 30?
    Question 16: If the Board does not adopt its proposal to calculate 
a firm's stress capital buffer requirement by averaging stress test 
results over two consecutive years, should the Board consider a lower 
threshold to determine materiality, such as 10 basis points for the 
individual firm threshold instead of the proposed 20 basis points? What 
would be the advantages and disadvantages of a lower threshold?

D. Annual Disclosure of Scenarios

    Under the proposal, the Board would annually publish for comment 
the proposed stress test scenarios by October 15 of the calendar year 
prior to the stress test, for at least a 30-day period. The timing of 
the release and duration of the comment period will allow for 
sufficient time to respond to comments and finalize the scenarios 
within the current window for publishing final scenarios by February 15 
in each annual stress test cycle.\70\ The disclosure of the annual 
scenarios for comment, along with the implementation of additional 
scenario variable guides and revisions to the Scenario Design Policy 
Statement, would meaningfully improve the transparency, public 
accountability, and predictability of the annual stress tests.
---------------------------------------------------------------------------

    \70\ Trading or other components of the scenarios, and any 
additional scenarios used by the Board, would continue to be 
communicated by March 1 of the calendar year in which the stress 
test is performed. 12 CFR 238.132(b); 12 CFR 238.143(b)(2)(i); 12 
CFR 252.14(b)(2)(i); 12 CFR 252.44(b); 12 CFR 252.54(b)(2)(i).
---------------------------------------------------------------------------

    The publication of macroeconomic scenarios in October would use 
nowcasts, which are projections under baseline conditions, to determine 
the jump-off points for the proposed scenario variable paths. The final 
scenarios would be updated to include actual data. The paths of 
scenario variables may be adjusted to some extent between the initial 
scenario publication and the finalized scenario to reflect these 
updated values.
    By designing and publishing the guides described in Section IX.G of 
this Supplementary Information, the Board expects that the annual 
severely adverse scenarios will generally be more consistent and 
predictable year-to-year. As a result, the Board weighed whether 
publishing the annual scenarios for comment in a typical year would 
contribute meaningful additional accountability that would improve the 
stress test program, and whether the Board should limit publication of 
the annual scenarios for comment to situations where the Board is 
proposing to incorporate a salient risk into the scenarios that is not 
described in this proposal. However, in the interest of enhancing 
transparency and public accountability, the Board determined to 
maintain its current practice of publishing its annual scenarios and, 
further, to propose changes to Regulations LL and YY formalizing this 
disclosure process.
    Additionally, the Board plans to maintain its current practice of 
disclosing the final scenarios only after firms' portfolios are fixed, 
as disclosure of the final scenarios prior to the jump-off date of the 
stress test could incentivize firms to modify their businesses to 
minimize losses in the supervisory stress test without changing the 
actual risk profile of the firms. Therefore, the Board is proposing to 
move the jump-off date of the stress test from December 31 to September 
30. This proposed change is discussed in greater detail in Section VI.A 
of this Supplementary Information.
    Finally, as described in Section VI.B of this Supplementary 
Information, the Board is proposing to change the as-of date window for 
the global market shock to occur between October 1 of the calendar year 
two years prior to the year in which the stress test is performed to 
October 1 of the year prior to the year in which the stress test is 
performed. Therefore, the Board anticipates that the global market 
shock as-of date will have already occurred for most future proposals 
regarding the initial disclosure of the stress test scenarios. However, 
the Board has not yet announced the global market shock as-of date for 
the 2026 stress test and so cannot provide the exact relative shock 
values for certain global market shock variables since the relative 
shock values are a function of the actual data on the as-of date.
    For relative shocks associated with the 2026 global market shock, 
the data on the global market shock as-of date would be applied to 
determine relative shock values, which will be disclosed as part of the 
finalized scenarios. For example, if the Board proposes a shock to the 
BBB corporate spread of 200 basis points and the BBB corporate spread 
market level on the global market shock as-of-date is 400 basis points, 
then the relative shock to the BBB corporate spread would be 200/400, 
or 50 percent, for the 2026 global market shock.
    Question 17: How should the Board publish the annual scenario for 
comment? For example, the Board could publish the scenario on the 
Board's website or include the text and supporting materials in a 
Federal Register notice. Alternatively, the Board could consider 
codifying each annual scenario as a part of Regulation YY. What would 
be the advantages and disadvantages of these options or other 
alternatives?
    Question 18: What are the advantages and disadvantages of 
publishing the annual scenarios for comment prior to the jump-off date 
of the annual stress test cycle?
    Question 19: What are the advantages and disadvantages of a 30-day 
comment period? Should the Board consider an alternative comment period 
length? If so, how long should the comment period be (e.g., 45 days, 60 
days, etc.)? When considering the appropriate length of the comment 
period, how should the Board evaluate trade-offs, for instance, between 
ensuring that the public has ample time to consider and comment on 
annual scenarios and ensuring that the stress test scenarios can be 
finalized before February 15?
    Question 20: How should the Board analyze comments received from 
the public on proposed scenarios? What types of information would be 
helpful to commenters in order to understand how the Board incorporates 
comments received on proposed scenarios before finalizing the annual 
scenarios?

E. Stress Capital Buffer Requirement Reconsideration Process

    Under the Board's capital plan rule, a firm may request 
reconsideration of the calculation of its preliminary stress

[[Page 51872]]

capital buffer requirement within 15 calendar days of receiving notice 
of the preliminary requirement.\71\ A request for reconsideration may 
include a request for an informal hearing on the firm's request for 
reconsideration; the Board may, in its sole discretion, order an 
informal hearing if the Board finds that a hearing is appropriate or 
necessary to resolve disputes regarding material issues of fact.\72\ 
The Board is not proposing to change this reconsideration process.\73\ 
However, the Board is requesting public input on potential enhancements 
to the stress capital buffer requirement reconsideration process. In 
particular, the Board seeks public input on the following question:
---------------------------------------------------------------------------

    \71\ 12 CFR 225.8(h)(2)(i); 12 CFR 225.8(i)(2); 12 CFR 
238.170(h)(2)(i); 12 CFR 238.170(i)(2).
    \72\ 12 CFR 225.8(i)(3)(ii); 12 CFR 225.8(i)(4); 12 CFR 
238.170(i)(3)(ii); 12 CFR 238.170(i)(4).
    \73\ Model adjustments made in response to a reconsideration 
request granted by the Board would not be considered model changes 
under the proposed enhanced disclosure process.
---------------------------------------------------------------------------

    Question 21: What enhancements, if any, should the Board consider 
making to its reconsideration request process? For example, the Board 
could allow firms more time to request reconsideration of their 
results, broaden or narrow the grounds for and scope of review, and/or 
modify existing reconsideration request requirements in light of the 
publication of the comprehensive model documentation and proposed 
enhanced disclosure process. What would be the advantages and 
disadvantages of these enhancements? What other changes, if any, should 
the Board consider making to the reconsideration requirements and 
procedures? What would be the advantages and disadvantages of those 
changes?

V. Revisions to the Stress Testing Policy Statement

    The Board is also proposing certain changes to the Stress Testing 
Policy Statement to (i) amend the section related to disclosure of 
information related to the stress test; and (ii) to align the Stress 
Testing Policy Statement with the proposed enhanced disclosure process.

A. Future Supervisory Stress Test Results Disclosures

    The Board's Stress Testing Policy Statement states that, in 
general, the Board does not share information regarding supervisory 
stress test results with firms that is not made available to the 
broader public. However, providing additional details to a firm about 
its own results could provide the firm with additional visibility into 
its stressed revenue and loss projections, including any underlying 
risks, and improve the firm's understanding of its stress capital 
buffer requirement. For example, additional results information would 
allow a firm to better understand how the stress test translates their 
balance sheet and income information into projected losses and revenue, 
which could help them better plan their business and understand the 
risk of their exposures. To provide additional transparency, the Board 
is therefore proposing to revise the Stress Testing Policy Statement to 
clarify that the Board will generally disclose information directly to 
a firm about the firm's supervisory stress test results that is not 
available to the broader public, so long as the Board discloses similar 
information to the other firms participating in a given stress test 
cycle. For example, the Board may provide a firm's common equity tier 1 
capital ratio during all quarters of the projection horizon. Providing 
firm-specific results directly to the affected firms even when that 
information is not disclosed to the broader public would allow firms to 
better understand their results while preventing potentially sensitive 
information about a firm from being shared with competitors. The Board 
would continue to disclose the supervisory stress test results to the 
public.
    Question 22: What are the advantages and disadvantages of revising 
the Stress Testing Policy Statement to clarify that the Board will 
generally share non-public information about a firm's results directly 
with a firm (provided that the Board is disclosing similar information 
to other participating firms)?

B. Other Revisions to the Stress Testing Policy Statement

    In addition, the Board is proposing to revise the Stress Testing 
Policy Statement to align it with the proposed enhanced disclosure 
process. For example, the Board is proposing to state that, during 
model development, it invites, evaluates, and responds to substantive 
public input on the stress test models. The Board is also proposing to 
revise the Stress Testing Policy Statement to clarify that its public 
disclosures about the stress test will now include comprehensive 
descriptions of the models and changes to those models.
    Question 23: What other changes could the Board make to the Stress 
Testing Policy Statement to reflect the enhanced transparency of the 
supervisory stress test or to supplement the Board's efforts to make 
the supervisory stress test more transparent and to facilitate public 
participation? What are the advantages and disadvantages of such 
changes?

VI. Other Revisions to the Stress Testing and Capital Plan Rules

    The Board is also proposing to revise the stress testing and 
capital plan rules to reflect the Board's efforts to disclose more 
information about the stress test scenarios.

A. Stress Test Jump-Off Date Change

    The Board is separately seeking comment on the proposed scenarios 
for use in the 2026 supervisory stress test. In general, disclosure of 
the proposed scenarios prior to the jump-off date of the supervisory 
stress test could incent firms to temporarily modify their businesses 
to affect the results of the stress test without changing the actual 
risk profile of the firms. The Board recognizes that the increased 
transparency around scenario design resulting from the disclosure of 
additional guides and a macroeconomic model used in that process would 
allow firms to anticipate the trajectories of key scenario variables. 
Using this information, firms could adjust their portfolios to specific 
aspects of the proposed scenarios in ways that would reduce measured 
losses without reducing the actual riskiness of the portfolios. Such 
changes to firm business profiles could also result in greater than 
typical quarter-to-quarter variability in the banking books of firms.
    To address this potential risk associated with increased 
transparency, the Board proposes to modify the jump-off date of the 
supervisory and company-run stress tests from December 31 to September 
30, while leaving unchanged the other dates associated with publication 
of the final scenario and stress test results.\74\ With respect to the 
capital planning rules, the Board proposes accomplishing this change 
through revision to the definition of ``planning horizon'' in 
Regulation Y and Regulation LL. This change would allow the Board to 
publish the scenario for comment after the jump-off date of the stress 
test, preventing firms from adjusting their exposures based on the 
stress test. However, this proposed change would introduce an 
additional quarter of staleness to the stress test and

[[Page 51873]]

stress test results. This change would also affect firms' capital plan 
submissions. Although the due date for firms' annual capital plan 
submissions would be unchanged, because of the proposed update to the 
definition of planning horizon, firms' capital plans would not project 
out as far. While the Board weighs these risks and considers adjusting 
the stress test jump-off date, the Board seeks input from the public 
regarding whether these risks are outweighed by the value to firms and 
the public by publishing scenarios prior to the jump-off date of the 
supervisory and company-run stress tests. Therefore, the Board seeks 
public comment on whether to propose such modifications to limit the 
ability of firms to adjust their balance sheets in response to the 
proposed scenario prior to the jump-off date of the stress test.
---------------------------------------------------------------------------

    \74\ The Board has experience operating the annual supervisory 
stress test with a September 30 jump-off date. See, e.g., Board, 
2015 Supervisory Scenarios for Annual Stress Tests Required under 
the Dodd-Frank Act Stress Testing Rules and the Capital Plan Rule 
(Oct. 23, 2014), https://www.federalreserve.gov/newsevents/pressreleases/files/bcreg20141023a1.pdf.
---------------------------------------------------------------------------

    Question 24: What are the advantages and disadvantages of retaining 
a jump-off date that would occur after the publication of the annual 
scenario for comment? Should the Board consider retaining the December 
31 jump-off date in order to promote transparency? Are there additional 
risks or trade-offs that the Board should consider?
    Question 25: What would be the advantages and disadvantages of 
modifying the jump-off date of the stress test from December 31 to 
September 30? If the Board were to modify the jump-off date, what other 
changes should the Board consider making to the stress test timeline? 
For example, what would be the advantages and disadvantages if the 
Board were to change the timing of a firm's capital plan submission? 
What would be the advantages and disadvantages of these changes?
    Question 26: Should the Board consider modifying the jump-off date 
of the stress test to a later date, rather than an earlier date, in 
order to accommodate a public comment period?

B. Global Market Shock Date

    The global market shock (GMS) is applied to market risk positions 
held by the firms on a given as-of date, which, under the Board's 
stress test rule, currently occurs between October 1 of the previous 
year and March 1 of the year of a given stress test cycle.\75\ Under 
the Board's regulations, the GMS can apply to both the supervisory 
stress test and the company-run stress test for applicable firms. For 
the supervisory stress test and the company-run stress test, the Board 
must generally provide each affected firm with a description of the GMS 
and with the specific GMS as-of date by March 1 of the year in which 
the stress test occurs.\76\ For the company-run stress test, the Board 
generally must also notify each affected firm by December 31 of year 
preceding the stress test that the firm is required to include 
additional components or scenarios in its company-run stress test.\77\
---------------------------------------------------------------------------

    \75\ See, e.g., 12 CFR 238.143(b)(2)(i); 12 CFR 252.14(b)(2)(i); 
12 CFR 252.54(b)(2)(i).
    \76\ See, e.g., 12 CFR 238.132(b); 12 CFR 238.143(b)(2)(i); 12 
CFR 252.14(b)(2)(i); 12 CFR 252.44(b); 12 CFR 252.54(b)(2)(i).
    \77\ See, e.g., 12 CFR 238.143(b)(4)(i); 12 CFR 252.14(b)(4)(i); 
12 CFR 252.54(b)(4)(i).
---------------------------------------------------------------------------

    The Board selects a cycle-specific as-of date each year and, 
typically, announces it to firms about two weeks later to ensure the 
firms retain necessary data. The as-of date is expected to change from 
year to year to avoid creating potential incentives for firms to take 
temporary trading positions. However, there is a comprehensive date 
selection process that, in practice, shortens the actual window during 
which the GMS as-of date is generally selected. A wider date range 
would allow the Board to capture a broader range of market risks across 
different time periods, thereby improving the risk capture of the 
global market shock. The Board therefore proposes revising the date 
range for the GMS as-of date to occur between (inclusive of) October 1 
of the calendar year two years prior to the year in which the stress 
test is performed to (exclusive of) October 1 of the calendar year one 
year prior to the year in which the stress test is performed. By way of 
example, this change would mean that for the 2026 supervisory stress 
test, the GMS as-of date could fall on any date between October 1, 
2024, through September 30, 2025. The Board proposes using this date 
range because it would allow the Board to choose from a full year's 
worth of potential GMS as-of dates. Additionally, the proposed range 
would include only dates prior to the release of the given stress test 
cycle's GMS for notice and comment. Therefore, firms subject to the GMS 
would not be able to use their knowledge of the GMS as-of date to 
update their balance sheet positions or adjust their portfolios to 
minimize stress losses without a commensurate reduction in risk 
profile.
    In conjunction with the proposal to change the GMS as-of date 
window, the Board also proposes to change the date by which the Board 
needs to notify affected firms of this as-of date from March 1 of the 
year in which the stress test occurs. Unless it determines otherwise, 
the Board must notify affected firms of the GMS as-of date by October 
15 of the year prior to the year in which the stress test is performed. 
The Board would continue to provide firms with a description of the 
GMS, as finalized, by March 1 of the calendar year in which the stress 
test occurs. Additionally, to conform to the proposed changes to the 
stress test timeline, the Board proposes to change the date by which 
the Board must notify firms that they are required to include 
additional components or scenarios in their company-run stress test 
from December 31 to September 30 of the year preceding the stress test. 
This change would ensure that firms are aware of the components to 
which they would be subject prior to the annual publication of the 
scenarios for notice and comment.
    Question 27: What are the advantages and disadvantages of modifying 
the window for the GMS as-of date in the stress test from October 1 of 
the calendar year one year prior to the year in which the stress test 
is performed through March 1 of the year in which the stress test is 
performed, to a date that is no earlier than October 1 of calendar year 
two years prior to the year in which the stress test is performed and 
that precedes October 1 of the calendar year one year prior to the year 
in which the stress test is performed? What alternative GMS as-of date 
ranges, if any, should the Board consider, and why? In addition to 
changing the GMS as-of date window, what other changes, if any, should 
the Board consider making to the stress test timeline? What effects, if 
any, would changing the window for the GMS as-of date have on any other 
aspects of the stress test or the stress test timeline?
    Question 28: What are the advantages and disadvantages of the 
proposed dates by which the Board would notify firms of the GMS as-of 
date, provide a description of any associated components, and notify 
firms of any additional components that they are required to include in 
their supervisory and company-run stress tests? What alternative dates, 
if any, should the Board consider for these activities and why? For 
example, to better ensure that more stakeholders provide input into the 
proposed GMS, the Board could wait until the scenarios are final before 
notifying firms which components they must include in their company-run 
run stress tests.
    Question 29: The GMS only considers a firm's positions on one as-of 
date and only under one set of shocks. Should the Board consider 
alternative approaches to further increase the risk capture of the GMS, 
such as applying the GMS to more than one as-of date or more than

[[Page 51874]]

one set of shocks for a given stress test? What would be the advantages 
and disadvantages of these alternative approaches? What other 
approaches should the Board consider to improve the risk capture of the 
GMS and why?

C. Amendment to the Dividend Add-On Component Calculation

    The dividend add-on component of the stress capital buffer 
requirement currently comprises planned dividends in the fourth through 
seventh quarters of the planning (or projection) horizon of the 
supervisory stress test.\78\ Under the current framework, the planned 
dividends that are incorporated in the stress capital buffer 
requirement align with the effective date of the stress capital buffer 
requirement (that is, October 1 generally is the first day of the 
fourth quarter of the existing planning horizon) and last for the one-
year period through which the stress capital buffer requirement is 
expected to be effective (that is, through the seventh quarter of the 
existing planning horizon, after which the following year's stress 
capital buffer requirement would be expected to take effect).
---------------------------------------------------------------------------

    \78\ See 12 CFR 225.8(d)(16); 12 CFR 238.130. The planning (or 
projection) horizon for the supervisory stress test is nine 
consecutive quarters starting on the jump-off date of the 
supervisory stress test.
---------------------------------------------------------------------------

    As part of this rulemaking, the Board is proposing to change the 
jump-off date of the stress test from December 31 to September 30. To 
maintain alignment between the dividend add-on component of the stress 
capital buffer requirement and the one-year period during which the 
requirement typically is effective, the Board proposes to change the 
dividend add-on component to cover dividends issued in quarters five 
through eight, instead of quarters four through seven, of the planning 
horizon of the supervisory stress test. This change involves updates to 
the capital plan rules, at Regulation Y and Regulation LL, to any 
references to the relevant quarters of the planning horizon.\79\ This 
proposed revision is intended to maintain the alignment between the 
dividend add-on component and the one-year period during which the 
stress capital buffer requirement generally is effective, assuming the 
proposal to move the jump-off date of the stress test to September 30 
is adopted. If this aspect of the proposal is not adopted, then the 
Board would not adjust the planning horizon period for planned 
dividends.

    Such a change to the planning horizon period has likewise been 
proposed as part of the Board's proposed Modifications to the Capital 
Plan Rule and Stress Capital Buffer Requirement, issued in April 2025, 
in order to similarly maintain alignment between that proposal's 
updates to the effective date of a firm's stress capital buffer 
requirement and the dividend add-on component.\80\ Should both 
proposals be finalized as proposed, the Board would expect to adjust 
the dividend add-on component of the stress capital buffer requirement 
to maintain alignment between the dividend add-on component and the 
one-year period in which the stress capital buffer requirement 
generally is effective. In such an instance, the Board would expect to 
change the dividend add-on component to cover dividends issued in 
quarters six through nine of the planning horizon of the supervisory 
stress test.

    Question 30: What would be the advantages and disadvantages of the 
proposed change to the dividend add-on component of the stress capital 
buffer requirement?

VII. Revisions to the FR Y-14A/Q/M

    To reduce regulatory reporting burden, support the proposed model 
changes, and improve risk capture, the Board is proposing several 
revisions to the FR Y-14A/Q/M. To reduce regulatory reporting burden, 
the Board is proposing to remove items and documentation requirements 
that are no longer needed to conduct the supervisory stress test. For 
example, the proposal would remove certain FR Y-14 supporting 
documentation requirements that are no longer needed to assess a firm's 
FR Y-14 submission. The Board also proposes to collect additional data 
that would support the supervisory stress test models and improve risk 
capture. For example, to capture data in a manner that aligns better 
with the treatment of private equity under the macroeconomic scenario, 
the proposal would include revisions for reporting private equity 
exposures and associated hedges. Additionally, to broaden the 
consideration of hedges and revenue and loss sharing agreements in the 
stress test, the Board is proposing revisions that would capture more 
data on various types of hedges or revenue and loss sharing agreements. 
Lastly, the Board is proposing several minor revisions to clarify the 
FR Y-14 instructions or align with the proposed changes to the stress 
test timeline. The proposed revisions are described in Section XI.A of 
this Supplementary Information.

VIII. Proposed Changes to the Stress Test Modeling Framework

    The Board is proposing to use the models described in the documents 
posted on the Board's website to generate results for the 2026 
supervisory stress test. Included in these descriptions are some model 
specifications that were not used to conduct the 2025 supervisory 
stress test but are proposed to be used for the 2026 supervisory stress 
test. These proposed model changes are summarized in Section 
VIII.A.\81\ In addition, a detailed description of and rationale for 
each of these proposed model changes is provided in a separate document 
posted on the Board's website with the comprehensive model 
documentation. Section VIII.B of this Supplementary Information 
provides an analysis of the potential effects of the proposed changes. 
Based on this analysis, implementing the proposed model changes and 
proposed revisions to the global market shock scenario design in the 
2024 and 2025 stress tests would have, independent of other factors, 
increased the aggregate projected common equity tier 1 (CET1) stress 
ratio, on average, by 29 basis points. This is equivalent to a 
reduction in stress capital buffer requirements of approximately 23 
basis points or approximately 2.2 percent of current required capital.
---------------------------------------------------------------------------

    \81\ These proposed changes would constitute ``model changes'' 
under the proposed definition of ``model change,'' as discussed in 
Section IV.B of this Supplementary Information.
---------------------------------------------------------------------------

A. Proposed Changes to Stress Test Models

    The Board is proposing several changes to the supervisory stress 
test models for the 2026 stress test, which are discussed in more 
detail in the Model Changes document provided on the Board's website, 
at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. More significant proposed changes to the Pre-provision Net 
Revenue and Operational Risk Models are described within the 
comprehensive model documentation, also available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. The 
Board is requesting comment on the proposed changes, together with the 
model documentation.
    With respect to the credit risk models, the Board is proposing to 
change how it uses geography in scenario variables (First Lien, Home 
Equity, Credit Cards,

[[Page 51875]]

Auto, and Commercial Real Estate Models); change how it treats 
foreclosures under judicial supervision (First Lien and Home Equity 
Models); change how it calculates loss given default for international 
loans (Commercial Real Estate and Corporate Models); change how it 
includes losses attributable to accrued interest and carrying costs 
(First Lien and Home Equity Models); change how it uses multipliers in 
the Provisions Model; revise the mortgage loss given default model in 
the First Lien Model; revise the bank card model in the Credit Card 
Model; change how it projects losses on auto leases in the Auto Model; 
and update the probability of default, loss given default, and exposure 
at default components in the Corporate Model.
    With respect to the market risk models, the Board is proposing to 
update several of its market risk models for the 2026 stress test, 
including to simplify the Yield Curve Model; adjust its process for 
projecting credit valuation adjustments for derivative positions in the 
Credit Valuation Adjustment Model; lower the loss given default 
assumption amount and loan equivalent factor parameter in the Fair 
Value Option Model; update and simplify the Securities Model; and 
exclude additional counterparties in the Largest Counterparty Default 
Model.
    With respect to the net revenue models, the Board is proposing an 
alternative suite of pre-provision net revenue component models that 
depart from the current panel regression-based approach. This 
alternative suite is described in the Pre-provision Net Revenue Model 
documentation, available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm. The Board is also proposing 
to discontinue the current regression model used to project operational 
risk losses and instead project losses with a distributional model. 
This alternative model is described in the Operational Risk Model 
documentation, also available at https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.
    Aggregate impacts on regulatory capital of the model changes 
described above are small (see Table 2). Across risk stripes, the 
proposed model changes would reduce credit, market, and operational 
losses, which would be balanced by the effects of the proposed model 
changes to the Pre-provision Net Revenue Model. Across firm categories, 
GSIBs would observe modest increases in aggregate projected CET1 stress 
ratio under the proposed changes. Firms subject to Category II-III 
standards would also observe a modest increase in their projected CET1 
stress ratio.
    Question 31: The Board invites public comment on these proposed 
model changes. What other changes, if any, should the Board consider 
implementing in the 2026 stress test cycle, either instead of or in 
addition to the proposed changes?
    Question 32: What other information or data should the Board 
consider to assess the quantitative economic impact of the proposed 
model changes and why?

B. Analysis of Proposed Model Changes

    To further enhance the transparency of the stress test models, this 
section analyzes the potential effects of the proposed model changes 
described in Section VIII.A of this Supplementary Information, and the 
liquidity horizon revisions to the global market shock scenario design 
described in Section IX.H of this Supplementary Information, that 
inform the Board's determination of firms' stress capital buffer 
requirements.
    In aggregate, the stress test model and scenario changes are not 
expected to materially change capital requirements for firms subject to 
the supervisory stress test, across various stress scenarios and jump-
off conditions at the start of the test. To illustrate the effect of 
these proposed model changes, this analysis averaged the impact of 
these changes on the CET1 stress ratio for a balanced sample of 30 
firms subject to the 2024 stress test and expected to participate in 
the 2026 stress test, then aggregated the averages.\82\ The analysis 
estimates that the proposed model and scenario changes, independent of 
other models and components, could have resulted in an increase of 29 
basis points in the average aggregate CET1 stress ratio. This is 
equivalent to a reduction in stress capital buffer requirements of 
approximately 23 basis points or approximately 2.2 percent of current 
required capital. The analysis estimates that the model changes would 
reduce stress capital buffer requirements by approximately 13 basis 
points, and that the revisions to the global market shock scenario 
design, described in Section IX.H of this Supplementary Information, 
would reduce stress capital buffer requirements by approximately 10 
basis points. For U.S. GSIBs, the analysis estimates a decline of 25 
basis points of stress capital buffer requirements.
---------------------------------------------------------------------------

    \82\ This analysis used the 2024 and 2025 scenarios, 
respectively, and the same data used for those years' stress tests. 
The estimated impact of these changes remains highly sensitive to 
the stress test scenario and firm-specific data for each year. While 
the precise impact will vary each year based on stress test 
scenarios and specific firm data, Board analysis across a range of 
conditions shows that capital requirements should remain essentially 
unchanged.
---------------------------------------------------------------------------

    As the U.S. banking system's 13.0 percent CET1 capital ratio (8.2 
percent leverage ratio) is well within the estimated optimal range in 
the literature,\83\ the net benefit of modest changes to the overall 
level of banking system capital is small.\84\ However, as discussed 
further below, the proposed model changes have varied effects on 
capital requirements across loss type and firm category.
---------------------------------------------------------------------------

    \84\ Ratios are based on the aggregate of all FR Y-9C filers as 
of Q1 2025, which generally excludes holding companies with less 
than $3 billion in consolidated assets and depository institutions 
without parent holding companies. The aggregate CET1 ratio 
additionally excludes holding companies that have opted in to the 
Community Bank Leverage Ratio requirement, and reflects standardized 
risk-weighted assets.
---------------------------------------------------------------------------

    Based on this analysis, the proposed model changes are expected to 
result in more risk-sensitive capital requirements, independent of 
their effect on the level of requirements. Specifically, implementation 
of the proposed model changes would render the models more stable, 
likely reducing misalignment between firms' losses under stress and 
their respective stress capital buffer requirements. To the extent that 
the stress capital buffer requirements are affected by these proposed 
model changes and are a part of firms' most-binding capital 
constraint,\85\ the proposed model

[[Page 51876]]

changes would thereby improve the risk sensitivity--and efficiency and 
effectiveness--of capital requirements.
---------------------------------------------------------------------------

    \85\ The capital requirements of firms with stress losses plus 
dividend add-ons reliably below the 2.5 percent capital conservation 
buffer would be unaffected by the proposed model changes.
---------------------------------------------------------------------------

    This analysis recognizes that the limited overall effect on 
stressed CET1 capital ratios masks significant variation across the 
different loss drivers. As shown in Table 2 below, the proposed model 
changes could result in less severe credit, market, and operational 
loss estimates--which would be driven by overhauling the wholesale 
corporate probability of default model and discontinuing the 
macroeconomic regression approach for operational risk loss estimation, 
as described further in the Corporate Model and Operational Risk Model 
descriptions. However, the proposed changes to the Pre-provision Net 
Revenue Model would offset these loss reductions. By reducing the 
reliance of net revenue projections on recent outcomes and relying more 
on firm projections of net noninterest income, the projections of net 
revenue would be more consistent with a stress scenario and would 
better align with firms' projections.

    Table 3 below provides a separate analysis of estimates of stress 
losses across firm types that are subject to the stress capital buffer 
requirement. The analysis shows the reduction in hypothetical stress 
losses is concentrated at larger firms.

IX. Proposed Changes to the Scenario Design Policy Statement

    The Board is also proposing to make several changes to the Scenario 
Design Policy Statement. While many of these proposed changes are 
technical in nature, this section identifies substantive changes and 
requests comment on those proposed changes.
    Question 33: The Board invites comment on all aspects of the 
technical and substantive proposed revisions to the Scenario Design 
Policy Statement. What are the advantages and disadvantages of these 
proposed changes? What would be the advantages and disadvantages if the 
Board were to consider describing the Board's expectations for 
additional components of the scenario design framework?

A. Changes to the Background and Overview and Scope Sections

    The Board is proposing to make limited changes to the first two 
sections of the Scenario Design Policy Statement, which address 
background and overview and scope topics, respectively. In the 
background section, the Board would clarify that the stress tests 
primarily focus on credit risk, operational risk, and market risk. The 
inclusion of operational risk in this list helps clarify the Board's 
continued focus on designing a supervisory tool that makes a valuable 
forward-looking assessment of large financial companies' capital 
adequacy under hypothetical economic and financial market conditions. 
The Board would also clarify that it expects to provide only two 
different sets of macroeconomic scenarios for both the supervisory and 
company-run stress tests. These two sets of macroeconomic scenarios are 
the baseline and severely adverse scenario. This change would clarify 
the quantity of macroeconomic scenarios the Board expects to provide, 
consistent with the removal of a separate adverse scenario.\86\
---------------------------------------------------------------------------

    \86\ 84 FR 59032, 59061 (Nov. 1, 2019).
---------------------------------------------------------------------------

    In the overview and scope section, the Board would make conforming 
edits to the description of the organization of the Scenario Design 
Policy Statement to reflect the changes discussed earlier in this 
proposal.
    Question 34: What additional changes, if any, should the Board 
consider making to these sections, and why? What would be the 
advantages and disadvantages of providing more than two scenarios? What 
are the

[[Page 51877]]

advantages and disadvantages of the Board's continued focus on credit, 
operational, and market risk?

B. Changes to the Content of the Stress Test Scenarios Section

    The Board is proposing to make two general changes to this section, 
which describes the Board's expectations for the content of the 
published stress test scenarios.
    First, as described below, this section would be amended to clarify 
that the Board expects to generally publish two different macroeconomic 
scenarios: the baseline and severely adverse scenarios. This section 
would also be revised to clarify that the Board expects to invite 
comment on severely adverse scenarios.
    Second, as described in Section IX.H of this Supplementary 
Information, the Board is proposing to make certain changes related to 
the global market shock component. See Section IX.H of this 
Supplementary Information for a discussion of those changes.
    Question 35: What additional changes, if any, should the Board 
consider making to these sections, and why?

C. Approach for Formulating Macroeconomic Assumptions in the Baseline 
Scenario

    The Board is proposing to provide additional details describing the 
process by which the Board would set the paths of the variables in the 
baseline and severely adverse scenarios. In particular, the amendments 
reflect that the Board would post on the Board's website a description 
of the macroeconomic model utilized to support the construction of the 
baseline and severely adverse scenarios in the annual stress test. By 
posting a description of this model (the ``macroeconomic model for 
stress testing'') on the Board's website, the Board expects to improve 
the transparency, public accountability, and predictability around the 
Board's scenario design framework, particularly with respect to the 
baseline scenario and certain variables in the severely adverse 
scenario. The Board recognizes that, while these enhancements are 
consistent with the Board's goal of increased transparency in the 
supervisory stress test, they may constrain the design of the scenario 
paths for some variables to follow those prescribed by the 
macroeconomic model for stress testing. Nevertheless, the Board expects 
that other aspects of the proposed changes to the Scenario Design 
Policy Statement will preserve sufficient flexibility to allow the 
Board to adjust the severity of the annual scenario based on relevant 
indicators of economic and financial conditions and other emergent 
procyclical factors. Importantly, the Board uses these models to 
generate paths for the scenario variables only. These models are used 
solely for stress testing purposes and the output is not a forecast of 
the Board.
    Question 36: What are the advantages and disadvantages of adopting 
a macroeconomic model for stress testing to guide the selection of 
certain variables in the baseline and severely adverse scenarios?
    Question 37: What additional changes, if any, should the Board 
consider making to this section, and why?

D. Scenario Narrative: Refinement to the Recession Approach

    A number of considerations contribute to the Board's formulation of 
the severely adverse scenario. As a starting point, the basic approach 
adopted by the Board is the recession approach--the notion that the 
Board will construct a scenario informed by the historical paths of 
macroeconomic and financial market variables across post-war U.S. 
recessions. However, different recessions have differed in important 
respects, and a simple recreation of a given episode or an average over 
all recessions would fail to reproduce important potential stressors to 
firms' balance sheets. Hence, in applying the recession approach, the 
Board develops a specific narrative characterizing the hypothetical 
recession represented by the scenario to help inform the specific paths 
for scenario variables. This narrative combined with data are then 
modified to account for the Board's stress testing principle of 
conservatism alongside other considerations offered by the literature 
on stress testing including a goal to develop sufficient severity and 
credibility of the scenarios, and a goal to not add sources of 
procyclicality to the financial system, as described below.\87\ This 
section gives an overview of these considerations and other details, 
providing a common structure for the discussion outlined in the guides 
for individual variables under this framework, in Section IX.G of this 
Supplementary Information.
---------------------------------------------------------------------------

    \87\ 12 CFR 252, Appendix B.
---------------------------------------------------------------------------

The Recession Approach
    The Board intends to continue to use a recession approach to 
develop the severely adverse scenario. Under the recession approach, 
the Board expects to specify the future paths of variables to reflect 
conditions that characterize post-war U.S. recessions, generating 
either a typical or specific recreation of a post-war U.S. recession. 
The Board chose this approach in developing past scenarios, and in the 
Scenario Design Policy Statement, because it has observed that the 
conditions that typically occur in recessions--such as increasing 
unemployment, declining asset prices, and contracting loan demand--can 
put significant stress on firms' balance sheets. This stress can occur 
through a variety of channels, including higher loss provisions due to 
increased delinquencies and defaults, losses on trading positions 
through sharp moves in market prices, and lower bank income through 
reduced loan originations. For these reasons, the Board expects that 
the paths of economic and financial variables in the severely adverse 
scenario should, at a minimum, resemble the paths of those variables 
observed during a recession. The guide for each variable in this 
framework reviews the movements of that variable across past recessions 
and bases the formulation of its scenario path on that analysis. While 
the recession approach provides a starting point for the formulation of 
the scenario, recessions are not all the same. The length and depth of 
recessions differ, as do the parts of the economy and financial markets 
that are most affected, so the Board must include other considerations 
in its scenario design.
The Scenario Narrative
    Because recessions have differed in cause, character, and 
consequence--from oil price shocks and housing slumps to asset-price 
busts and pandemics, from short to long, and from mild to moderate to 
severe--the Board augments the basic recession approach with an annual 
scenario narrative. The annual scenario narrative provides qualitative 
direction on how the Board builds that year's severely adverse 
scenario.
    While some specifics of the narrative may be adjusted on a year-to-
year basis to reflect developments in the macroeconomic and financial 
environment, the overall narrative motivating scenario design will be 
that of a sharp recession triggered by an adverse shock to financial 
markets. Under the proposal, the Board expects that the macroeconomic 
scenario used in the Board's annual supervisory severely adverse 
scenario will begin with a sudden and significant increase in 
uncertainty and associated rapid deterioration in risk appetite that 
cause a spike in financial market volatility and a sharp decline in 
many U.S. and

[[Page 51878]]

foreign financial assets. The resulting turmoil would disrupt funding 
markets and lead to widespread deleveraging, including forced sales of 
illiquid assets at fire sale prices by a range of financial firms and 
some temporary breakdowns in the typical correlations between financial 
asset prices. (Such sharp changes in financial conditions have been 
observed previously in response to the outbreak of COVID-19 or regional 
wars, the failure or distress of a large financial institution, or 
sudden shifts in the economic policies in advanced economies.)
    Under the Board's recession approach, the Board expects that, 
although financial market functioning returns to normal within a few 
months of the initial shock, uncertainty remains high and risk appetite 
remains low for an extended period. The sustained flight to quality 
would be expected to push down risk-free interest rates but keep credit 
conditions tight and financial asset prices depressed for several 
quarters. The market dysfunction would cause a contraction in the 
supply of credit from other types of financial intermediaries that 
would create demands on banks to provide substantial liquidity to 
existing customers with formal credit lines. Banks would also make ad 
hoc decisions to support customers without formal arrangements when 
doing so could lead to lower losses on their existing loans.\88\ This 
shift in demand for credit toward banks from other financial 
intermediaries would lead to banks' balance sheets remaining constant 
even as overall credit demand declines.\89\ This feature of the 
scenario is supported by the stress testing principle of 
conservatism.\90\ To that end, maintaining higher capital requirements 
during periods of economic expansion ensures that stress tested firms 
employ sufficient capital to absorb losses and support the economy 
during a downturn.
---------------------------------------------------------------------------

    \88\ For example, in June 2020 the Federal Financial 
Institutions Examination Council issued interagency guidance to bank 
examiners stating, ``examiners will not subject a . . . modified 
loan to adverse classification solely because the value of the 
underlying collateral has declined . . ., provided that the borrower 
has ability to repay . . .'' See Interagency COVID-19 Examiner 
Guidance, https://www.federalreserve.gov/newsevents/pressreleases/files/bcreg20200623a1.pdf.
    \89\ Commercial and industrial loans grew 20 percent in 2007 as 
credit markets seized at the beginning of the 2007-2009 financial 
crisis. See M. Bech & Tara Rice, Profits and Balance Sheet 
Developments at U.S. Commercial Banks in 2008, 95 Fed. Rsrv. Bull. 
A57-97 (2009), https://www.federalreserve.gov/pubs/Bulletin/2009/articles/bankprofit/default.htm. For COVID-19, see H. Ennis & A.

Richmond Economic Brief No. 21-05 (Feb. 2021).
    \90\ 12 CFR 252, Appendix B.
---------------------------------------------------------------------------

    In the scenario, the news from financial markets would cause near-
immediate decisions by consumers to curtail spending and by businesses 
to cut payroll and cancel planned investments, leading to a demand-
driven contraction in economic activity putting downward pressure on 
inflation. The initial disruption to spending and employment along with 
tightening credit conditions would trigger a negative feedback loop 
that results in further declines in payrolls, investment, and spending 
in subsequent quarters. With businesses shrinking or failing in the 
scenario, demand for commercial real estate would decrease 
significantly relative to supply, leading to large declines in 
commercial property prices. Meanwhile, rising household financial 
distress would lead to increased supply of homes for sale and reduced 
household formation, which would depress residential real estate 
markets.
    The financial market dysfunction and deepening recession in the 
United States would spill over to its major trading partners, including 
the euro area, United Kingdom, Japan, and Developing Asia. Those areas 
would experience declines in economic activity commensurate with the 
global slowdown running from 2008 to 2010. Consistent with existing 
stress testing principles, this scenario assumes that permanent 
government stabilization programs (e.g., unemployment insurance) and 
monetary policy in the United States and elsewhere would function 
normally, but that there would be no extraordinary measures taken by 
fiscal or financial authorities to support the economy or financial 
markets during this time. The specific implications of this narrative 
for scenario variables are detailed in each guide, but the narrative 
interacts importantly with the recession approach: financial recessions 
often exhibit different properties than other recessions, as they are 
often steeper, deeper, and more drawn-out than typical, non-financial 
recessions.\91\ Adopting this scenario narrative reflects a principle 
of conservatism, and is in line with recommendations from the stress 
testing literature, as discussed in Section IX.F of this Supplementary 
Information.
---------------------------------------------------------------------------

    \91\ See, e.g., C. Reinhart & K. Rogoff, This Time Is Different: 
Eight Centuries of Financial Folly (2009).
---------------------------------------------------------------------------

    Question 38: The Board invites comment on all aspects of how the 
Board designs the scenario narrative in the annual stress test. What 
are the advantages and disadvantages of adopting this financial 
recession approach? What other approaches, if any, should the Board 
consider adopting, and why? What adjustments, if any, to the financial 
recession approach should the Board consider adopting, and why?
Adding Salient Risks to the Severely Adverse Scenario
    Consistent with the Scenario Design Policy Statement, under this 
proposal, the Board expects that the severely adverse scenario would be 
developed to reflect the current level of vulnerabilities or risks to 
the banking sector that are apparent in relevant indicators of economic 
and financial conditions. The Board anticipates that the proposed 
guides for certain scenario variables described below provide an 
appropriate range of values to design the severely adverse scenario in 
most years. The waxing and waning of relevant indicators of economic 
and financial conditions will inform the Board's decisions about where 
to set the value of those parameters within those ranges for each 
variable.
    The Board continues to expect that there will be some important 
instances when it will be appropriate to augment the recession approach 
with salient risks and to set variables values inside of, and in some 
cases, outside of the ranges and values provided in the guides in the 
Scenario Design Policy Statement. As a result, each year, the Board 
will consider particular risks to the financial system and to the 
domestic and international macroeconomic outlook identified by its 
economists, bank supervisors, and financial market experts. The Board, 
using its internal analysis and supervisory information and in 
consultation with the Federal Deposit Insurance Corporation and the 
Office of the Comptroller of the Currency, will then determine whether 
any of those risks appear significantly more elevated than usual or, 
conversely, whether risks are unusually low at a particular time, such 
that they cannot be appropriately reflected by choosing values within 
the ranges of the proposed guides. In those cases, which it expects to 
be infrequent, the Board will make appropriate adjustments to the paths 
of specific economic variables. These adjustments will not always be 
reflected in the general severity of the recession and, thus, all 
macroeconomic variables; rather, the adjustments will sometimes apply 
to a subset of variables to reflect co-movements in these variables 
that are historically less typical.
    To assist the public in assessing the use of salient risks in the 
scenario, the Board considered the following examples. A stress test 
initiated in a

[[Page 51879]]

period of unusually high uncertainty and rapid deterioration in 
economic and financial conditions, such as the first quarter of 2009 or 
the first quarter of 2020, likely would prove challenging for the 
ranges in this proposed framework. In each case, the prevailing 
conditions made it plausible that key variables would settle beyond the 
range of their previous peak or trough values, on which the guides for 
the variables in the severely adverse scenario are calibrated. Although 
the unemployment guide remained flexible enough to respond to the spike 
in the unemployment rate to nearly 15 percent during the first months 
of the COVID-19-related business closures in 2020, the paths of other 
variables may have needed to be adjusted more severely if the economy 
had not recovered as quickly as it did.
    As another example, the Board may become increasingly concerned 
about vulnerabilities related to a particular asset class that was 
experiencing rapid and persistent price increases supported by 
increasingly leveraged investors. Those circumstances existed in the 
housing market in the early 2000s and may have tested the credibility 
of a guide framework based solely on past performance of home prices, 
given that up until then, the price index for homes the Board uses for 
stress testing had rarely experienced a decline.\92\

Estate, Z.1 Release (Financial Accounts of the United States), 
Federal Reserve Board (series FL075035243.Q).
---------------------------------------------------------------------------

    Sometimes, the salient risk may arise within an asset class. The 
Board most recently incorporated this type of salient risk in the 2024 
stress test scenario. That year, the Board noted unusually high 
vulnerabilities in types of commercial properties that could be most at 
risk for a sustained drop in income and asset values due to the 
prevalence of remote work.\93\

Features of the Severely Adverse Scenario,'' at 12-13 (Feb. 2024),

---------------------------------------------------------------------------

    The Board is proposing two changes to its consideration of salient 
risks in the severely adverse scenario. First, the Board would remove 
paragraph 4.2.4(d) from the Scenario Design Policy Statement. Removing 
this paragraph could help improve the transparency of the scenario 
design process by limiting the Board's expectations for considering 
risks of uncertain significance. While this approach would reduce the 
Board's ability to test for emerging and untested risks in the 
financial system through the severely adverse scenario, the Board 
expects that the remaining components of the Board's supervisory stress 
test should be sufficient to establish a credible severely adverse 
scenario.
    Second, where the Board does consider salient risks in designing 
the severely adverse scenario, the Board will endeavor to disclose and 
explain the Board's reasoning in the Board's publication of the annual 
stress test scenarios, and subsequently adjust those aspects of the 
scenario, if necessary, in response to those comments.
    Question 39: What are the advantages and disadvantages of the 
Board's approach to considering salient risks? What additional or 
alternative approaches, if any, should the Board consider for the 
consideration of salient risks? What additional or alternative 
circumstances should the Board take into account when evaluating 
whether to consider salient risks, if any?

E. Changes to Construction of Certain Variables in the Severely Adverse 
Scenario

    As noted above, the Board finalized changes to the Scenario Design 
Policy Statement in 2019 that established a guide that it would use in 
setting the size of the maximum change in the unemployment rate and the 
timing of its peak. The Scenario Design Policy Statement also 
introduced a guide to govern the size of the maximum decline in house 
prices in the severely adverse scenario. This proposal maintains those 
features of the guides for those two variables, introduces guides that 
will be used to set the changes in the values, and the timing of those 
changes, for more variables in the severely adverse scenario, and 
provides additional context for the path of each variable before it 
reaches the maximum change. In addition, the Board is separately 
disclosing a specific macroeconomic model that it proposes to use to 
translate the paths of certain variables that are set using the 
proposed guides into internally consistent projections for the 
remaining variables, such as the 3-month Treasury bill rate, GDP, 
Disposable Personal Income (DPI), and inflation.
    In addition to updating existing guides for the unemployment rate 
and house prices, the Board is proposing to establish a guide for each 
of the following variables: equity prices; the VIX index; 5-year 
Treasury yields; 10-year Treasury yields; BBB corporate bond yields; 
mortgage rates; commercial real estate prices; and certain 
international scenario values. These include all but one of the 
remaining financial market variables typically included in the domestic 
severely adverse scenario disclosure each year (the exception being the 
3-month Treasury bill rate, as discussed below).
    The Board uses guides to inform its determination of the behavior 
of these financial market variables in the severely adverse scenario, 
rather than model predictions, for several reasons. Although the 
parameters of the guides are calibrated based on an analysis of 
historical changes in those variables during recessions and the 
resulting set of scenario paths typically would be consistent with 
historical co-movements in those variables, using explicit forward-
looking models of these variables to determine scenario paths would be 
inconsistent with several stress testing principles, such as simplicity 
and transparency, as described below.
    Under a model-driven approach to determine the paths of these 
variables, each model would require the Board to identify, design, 
test, explain, and publish additional assumptions, variables, formulas, 
and parameters that would drive the results of the model. Models of 
financial market variables can be particularly unreliable during 
periods of severe stress like the environment envisioned by the 
hypothetical severely adverse scenario.\94\ Thus, the model-driven 
approach to determining these variables would contrast with the stress 
testing principle of using simpler and more transparent approaches, 
where appropriate.

1999).
---------------------------------------------------------------------------

    The Board believes that the guide-based approach also better 
achieves the stress testing principle of using a stable process that is 
reliably able to capture the impact of economic stress. These simple, 
transparent guides also will allow the Board to use its judgment at 
times when it is necessary to account for conditions that are plausible 
even if they have not been observed previously, consistent with the 
stress testing principle of conservatism. Finally, the guides better 
preserve the Board's ability to adjust the severity of the stress test 
to avoid adding to procyclical forces, when doing so is appropriate and 
consistent with fostering financial stability. The Board's judgment 
about the appropriateness of the annual stress test scenarios will 
reflect changes in the specific risks or vulnerabilities that the 
Board, in consultation with the other federal banking agencies, 
determines should be considered in the annual stress tests.\95\
---------------------------------------------------------------------------

    \95\ See 84 FR 6651, 6656 (Feb. 28, 2019).

---------------------------------------------------------------------------

[[Page 51880]]

    The paths for the remaining variables in the domestic scenario--
GDP, DPI, inflation, and the 3-month Treasury rate--will be informed by 
the Board's macroeconomic model for stress testing.\96\ In contrast to 
the guide-based approach described above for certain variables, the 
Board uses a model-driven approach for these remaining variables 
because they are particularly suited to model projections that are 
simple to produce and explain. As explained in the model documentation 
available on the Board's website, that model uses a set of well-studied 
longer-run economic relationships that have proven to be useful in a 
variety of economic conditions and modeling frameworks. These include 
Okun's Law, a Phillips Curve, and an inertial Taylor Rule.\97\ The 
Board acknowledges that increasing the predictability of the paths of 
scenario variables in this way could reduce the dynamism of the stress 
test or incent firms to optimize their portfolios in ways that reduce 
capital requirements, perhaps without a commensurate reduction in risk. 
However, the guides and the model are constructed to remain flexible 
enough to ensure that the Board can adjust the severely adverse 
scenario to capture emerging risks and changes in the level of systemic 
risk since the previous stress test in a timely fashion. This 
flexibility includes the ability to increase scenario severity when 
systemic risks may have built up during robust economic expansions or 
periods when risk appetite is high or to avoid adding sources of 
procyclicality through the stress test. The proposal continues to 
ensure that the scenarios maintain a minimum severity level, even when 
economic and financial conditions are strained. Setting a floor for the 
severity of the scenario is appropriate because risks that built up 
during an economic expansion can persist at financial intermediaries 
during downturns and because firms that are under stress sometimes take 
imprudent risks that they believe will facilitate recovery.\98\
---------------------------------------------------------------------------

    \96\ This approach is consistent with how the Board has designed 
recent stress test scenarios. See id. at 6659.

Incentives and the Misallocation of Credit in Japan, 95 Am. Econ.

---------------------------------------------------------------------------

    The Board also considered that employing the guides or the 
macroeconomic model for stress testing sometimes may reduce the 
severity of some aspects of the scenario relative to what the currently 
less-constrained scenario design process would achieve, and in other 
cases it may result in higher severity for some aspects of the scenario 
than might otherwise be the case. The flexibility in the guides should 
be sufficient for the Board to account for those eventualities by 
choosing offsetting values across multiple guides that create the 
appropriate overall severity of the scenario.
    Question 40: What are the advantages and disadvantages of using 
guides and the macroeconomic model for stress testing to guide the 
setting of scenario variables in the severely adverse scenario? What, 
if any, alternatives to using a macroeconomic model to set the 
projection paths of other variables should the Board consider?

F. Scenario Design Principles Derived from Stress Testing Literature: 
Severity, Credibility, and Procyclicality

    In designing the guides for the construction of the severely 
adverse scenario presented in this framework, the Board is informed by 
the stress testing literature, which provides certain principles for 
scenario design,\99\ which are also reflected in the Board's Stress 
Testing Policy Statement.\100\ First, the literature emphasizes the 
need for adequately severe scenarios, even when the economy and 
financial system are in a stressed condition--complementing the Board's 
principle of conservatism.\101\ Second, the literature offers insights 
on how historical data should inform the design of an adequately severe 
scenario, augmenting the Board's recession approach. Third, the 
literature highlights the need for stress tests to avoid adding to 
other sources of procyclicality in the financial system. In explaining 
the paths for variables in the severely adverse scenario, the guides 
provide specific applications of these principles, while this 
introduction provides an overview of their general meaning and 
rationale.

---------------------------------------------------------------------------

    The first principle derived from the literature concerns the need 
for sufficiently severe scenarios. Plainly, insufficient stress test 
severity can lead to adverse outcomes. Inadequately assessed risks lead 
to an underassessment of the associated credit losses and capital 
needs--the basic source of failures of many financial institutions 
during the 2007-2009 financial crisis which the Board's stress tests 
are meant to avoid. Frame et al. (2015) provide an in-depth analysis of 
how the assessment of risks (or stress test) conducted by the Office of 
the Federal Housing Enterprise Oversight (OFHEO) actually contributed 
to the failures of the Federal National Mortgage Association (Fannie 
Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac).\102\ 
Importantly, stress tests must be adequately severe both in good times 
and in bad.
---------------------------------------------------------------------------

    \102\ See S. Frame, C. Gerardi, & P. Willen, The Failure of 
Supervisory Stress Testing: Fannie Mae, Freddie Mac, and OFHEO,

government-sponsored mortgage agencies, Fannie Mae and Freddie Mac.
---------------------------------------------------------------------------

    In the context of stress testing during crises, in particular, 
there are additional arguments against insufficient stress test 
severity. Schuermann (2014) and Judge (2022) argue that insufficiently 
severe stress test scenarios can erode credibility and trust and impede 
timely and adequate policy responses to ongoing crisis developments, 
thereby exacerbating a downturn.\103\ Bernanke (2013) also highlights 
that stress tests in times of crisis should provide anxious investors 
with credible information about prospective losses.\104\ This 
literature points to the importance of sufficiently severe scenarios 
for the health of the financial system, including by maintaining 
credibility with the public and financial markets.

www.federalreserve.gov/newsevents/speech/bernanke20130408a.htm.
---------------------------------------------------------------------------

    Further evidence for the importance of sufficiently stressful 
scenarios to maintaining public credibility comes from past U.S. stress 
tests. For example, the rapid deterioration in the U.S. economy in 
early 2009 led to realized unemployment rates that approached the peak 
of the unemployment rate path in the severely adverse scenario used for 
the Supervisory Capital Assessment Program (SCAP) in 2009.\105\ In 
fact, the scenario peak for the unemployment rate hypothesized would 
reach only 8.9 percent at the end of 2009, but as of

[[Page 51881]]

March 2009 the unemployment rate measured 8.5 percent and ultimately 
the unemployment rate peaked at 10 percent in October of 2009.\106\ 
Because the results of the SCAP determined the amount of capital that 
firms needed to raise in financial markets or through the Treasury's 
Capital Assistance Program, a scenario that turned out to be 
insufficiently severe could have left some firms undercapitalized and 
failed to achieve the goal of stabilizing the financial system.\107\
---------------------------------------------------------------------------

    \105\ See, e.g., E. Andrews & E. Dash, ``Government Offers 
Details of Bank Stress Test,'' N.Y. Times (Feb. 25, 2009), https://archive.nytimes.com/www.nytimes.com/indexes/2009/02/26/todayspaper/index.html.
    \106\ A similar concern related to insufficient scenario 
severity followed the announcement of the European Union's stress 
tests in 2018, with the criticism that the assumptions were milder 
than conditions in the 2007-2009 financial crisis. See F. Guarascio, 
``EU's 2018 Stress Test too Mild, Spared Weaker States--Auditors'', 
Reuters (Jul. 10, 2019), https://www.reuters.com/article/business/

    \107\ An explanation of the synergy between the SCAP and CAP is 
available here: Supervisory Capital Assessment Program & Capital 
Assistance Program (SCAP and CAP), U.S. Department of the Treasury, 
https://home.treasury.gov/data/troubled-assets-relief-program/bank-investment-programs/scap-and-cap.
---------------------------------------------------------------------------

    This example helps demonstrate the importance of the principle of 
severity when considering historical data and current conditions in the 
construction of an adequately severe scenario. While unemployment rates 
are discussed at length in the unemployment guide below, the maximum 
level of 8.9 percent specified in the 2009 SCAP, at the time, was well 
beyond the level reached in most post-war recessions. At the time the 
scenario was issued, a projected increase to 8.9 percent was thus very 
severe compared to outcomes over the past quarter century, but 
nonetheless proved lower than the actual realized peak in 2009.
    That experience reinforces the need for the framework to support 
variable paths that exceed levels observed in the historical data. 
Choosing a historical scenario has a price--``it does not test for 
anything new.'' \108\ While the recession approach dictates that 
variable movements follow historical recessions, when current 
conditions are already extreme, a credible scenario may replicate 
historical recessions in terms of the size of movements previously 
observed, leading to levels of variables that may exceed historical 
levels. Several of the guides in this framework allow, at times, for 
variables to exceed their historical range, either in levels or in 
changes, in order to maintain adequate severity.
---------------------------------------------------------------------------

    \108\ See Schuermann (2014), supra note 99.
---------------------------------------------------------------------------

    Ultimately, no single scenario can account for all potential 
contingencies. Therefore, the severely adverse scenario used in the 
Board's annual stress test must be sufficiently severe to ensure that 
banks will be resilient to a range of alternative and plausible 
scenarios that could generate net losses that are of similar 
magnitudes.\109\
---------------------------------------------------------------------------

    \109\ See Liang (2018), supra note 99.
---------------------------------------------------------------------------

    At the same time, the Board recognizes that the severity of the 
annual stress tests potentially can have unintended effects on firms' 
operations. For instance, the academic literature finds that stress 
tests improve financial stability by reducing riskier bank 
lending.\110\ Ensuring that firms are appropriately capitalized for the 
risks they are taking is a goal of stress testing; however, if those 
effects are not well aligned with the true riskiness of a particular 
type of loan, then stress tests could unintentionally reduce banks' 
credit supply. For instance, some evidence exists that counties in 
which stress tested banks had high market share may have experienced a 
lower supply of credit to small and young businesses, which are 
generally considered riskier than established businesses but can 
generate a disproportionate share of growth in employment and 
income.\111\ However, other research concludes that businesses largely 
offset the reduction in loans from banks that participate in the stress 
tests with other sources of credit. Those sources include loans from 
smaller banks not in the stress tests,\112\ debt issuance in capital 
markets, or loans from nonbank financial institutions.\113\ Moreover, 
these potential unintended effects on credit supply by stress tested 
firms must be weighed against the benefits, discussed above, that more 
credible stress tests bring to the economy and the financial system. By 
ensuring that firms have sufficient quantity and quality of loss-
absorbing capital to cover the risks that they are taking, the stress 
tests ensure the resilience and stability of the banking sector even in 
circumstances when stresses take unexpected forms.

---------------------------------------------------------------------------

    The balance of those advantages and disadvantages of scenario 
severity can change over time. Losses at financial institutions are 
more likely to arise when the economy slows. Profits are more robust 
during periods of economic growth, in turn increasing resources 
available to cover future losses. In other words, capital is naturally 
procyclical, having an underlying tendency towards a positive 
correlation with financial conditions. Moreover, when underlying 
conditions are favorable and firm losses are low, firms sometimes 
project forward an expectation for low losses, paving the way to take 
more risk.\114\ Conversely, when conditions are bad, firms may 
overcompensate and restrict credit even to otherwise creditworthy 
borrowers, exacerbating the downturn. Thus, firms' behavior may amplify 
underlying procyclicality.
---------------------------------------------------------------------------

    \114\ See A. Berger & G. Udell, The institutional memory 
hypothesis and the procyclicality of bank lending behavior, 13 J. 
Fin. Intermediation 458-495 (2004) (``Berger (2004)''); A.

Independent Community Bankers of America (Mar. 8, 2000) (``Greenspan 
(2000)''), https://www.federalreserve.gov/boarddocs/speeches/2000/20000308.htm.
---------------------------------------------------------------------------

    Stress tests could, through different designs, either amplify or 
mitigate this procyclicality. If stress tests are always more severe in 
bad times, despite an expectation that conditions could soon improve, 
then this severity would add undue stress to the financial system, 
reducing financial intermediation with negative implications for the 
macroeconomy. That said, the purpose of the stress test scenarios is 
not to serve as an explicit countercyclical offset to the financial 
system, but rather to ensure that the firms are properly capitalized to 
withstand severe economic and financial conditions. Hence, the Board 
adopts a middle path, seeking to specify the severely adverse scenario 
to avoid adding sources of procyclicality to the financial system, 
neither explicitly mitigating any existing procyclical tendencies nor 
magnifying them. Indeed, Kohn and Liang (2019) argue that the ability 
to adjust elements that potentially add procyclicality can be a major 
benefit of stress tests as ``banks with forward-looking, less-
procyclical capital buffers will not pull back as much when a downturn 
occurs.'' \115\

Stress Tests, Brookings Institute (Jul. 2019), https://www.brookings.edu/articles/understanding-the-effects-of-the-u-s-stress-tests/.
---------------------------------------------------------------------------

    In summary, in formulating the guides presented in this framework, 
the Board embraces three principles suggested by the literature: the 
importance of severity, the importance of credibility,

[[Page 51882]]

and the importance of not adding to procyclicality.
Stress Testing Literature and the Principle of Flexibility
    When considering these principles in light of the recession 
approach and the scenario narrative, the Board identified the 
importance of maintaining flexibility in the guides. While the Board 
intends to increase the transparency, public accountability, and 
predictability of stress tests through this proposal, these goals 
should not come at the expense of the overall effectiveness of the 
Board's stress tests.
    For instance, predictability and transparency could be achieved 
with a completely specified, entirely formulaic scenario that leaves no 
flexibility. However, simple, fixed guides may not achieve at least one 
of the goals of severity, credibility, or not adding to procyclicality. 
A guide that always increased unemployment to a fixed level, say 10 
percent, may not be credible or severe were the unemployment rate 
already at or close to that level. A guide that always increased 
unemployment by a fixed amount, say 4 percent, could add to 
procyclicality by implying lower losses when unemployment was low in 
good times and higher losses when unemployment was high in bad times. 
More sophisticated formulations might improve on simple rules by 
accounting for the factors affecting firms' balance sheets and overall 
economic and financial conditions. For many types of economic 
indicators used in the Board's scenario framework, however, a fixed 
rule for the design of a scenario variable that satisfied the 
principles related to procyclicality and severity laid out above could 
require a complex structure that would violate the Board's principle of 
simplicity.\116\
---------------------------------------------------------------------------

    \116\ Alongside conservatism, simplicity is one of the Board's 
principles for supervisory stress testing. See 12 CFR 252, Appendix 
B.
---------------------------------------------------------------------------

    A lack of simplicity is not, however, the only concern with a 
framework that eliminates flexibility. Unexpected shocks occur, like 
oil embargoes, national house price collapses, and pandemics. Moreover, 
the implications of these shocks are often not readily captured in 
concurrent data, especially their future effects on the economy and 
financial stability in the United States, and so on firms' future 
financial condition. Maintaining a degree of flexibility would allow 
the scenarios to adapt to evolving conditions while adhering to the 
principles outlined above.
    In specifying the guides in this framework, the Board seeks to 
maintain flexibility by specifying ranges for the peak or trough value, 
the timing of that value, or the speed of adjustment for many of the 
variables. The amount of flexibility in the guides, as measured by the 
size of ranges specified, is calibrated to be as narrow as possible 
while adhering to the principles laid out above and is based on 
research and analysis of the behavior of those variables during past 
recessions, consistent with the recession approach, or periods of 
stress in financial markets. In addition to suggesting typical ranges 
within which scenarios will vary, the Board seeks to provide 
explanations of how the guide flexibility would be applied in different 
economic and financial conditions.
    Generally speaking, the Board would design a more severe path for 
the scenario variables when it judged the level of systemic risks to be 
high, and a less severe path for the scenario variables when it judged 
systemic risks to be low. In some cases, the level of systemic risk can 
be tied to the level of specific indicators. For instance, when the 
unemployment rate is very high, the level of risk aversion also tends 
to be high, and that causes firms to reduce risk across their various 
business lines. In other cases, the Board would consider overall 
assessments by economists, supervisors, and financial market experts to 
assess the level of systemic risks, which typically incorporate many of 
the specific indicators mentioned in the discussions of individual 
guides below, when it is difficult to do so using individual or small 
sets of scenario variables.\117\
---------------------------------------------------------------------------

    \117\ For examples of relevant statistical analyses, see, e.g., 
V. Acharya et al., Measuring Systemic Risk, 30 Rev. of Fin. Studies 
2-47 (Jan. 2017); T. Adrian & M. Brunnermeier, CoVaR, 106 Am. Econ. 
Rev. 1705-41 (Jul. 2016).
---------------------------------------------------------------------------

    Therefore, the Board expects that it may choose to have similar 
severities for variable values in an annual scenario for those 
variables where the Board retains discretion within established ranges 
of the proposed guides. This expectation reflects the Board's 
consistent view that annual scenarios are not forecasts of potential 
future outcomes in the baseline or in a hypothetical stress 
environment. Establishing variable values with similar severity levels 
enhances the transparency and predictability of the annual scenarios, 
and reflects an expectation that these variables are likely to 
experience stress concurrently in a hypothetical stress scenario. As 
discussed below, if the Board were to determine that a specific salient 
risk should be addressed in a particular annual stress test, it would 
provide a specific assessment of that risk and the rationale for an 
alternative calibration of the variable's severity in the scenario 
disclosure for comment.
    While flexibility allows scenarios to adapt to fast-evolving 
conditions, the guides in this framework are based on long-lasting 
structural features of the economy. Macroeconomic history, however, 
features many examples where new data have contradicted long-held 
beliefs about underlying structural relationships. Also, the financial 
system is constantly evolving, presenting new risks and 
vulnerabilities. The relatively narrow ranges in the guides may not 
always allow for a fulsome response by the scenarios to significant 
developments. Therefore, the Board also sets out expectations for 
circumstances that could require additional flexibility in setting the 
specifications of the variables in the stress tests, so that the public 
can anticipate where the Board could adopt a specification that differs 
from those identified in the guides in this proposal. For instance, if 
events occur that alter the historical severity of a given variable, 
the Board could incorporate that data in its evaluation of the 
appropriate path for a given variable in annual scenarios that occur 
following such an event. The Board continuously monitors the 
macroeconomy and the financial system. If ongoing developments warrant, 
the Board may revisit this framework and adjust guides.
    Finally, the increased predictability and transparency of the 
scenario as specified in this framework may allow firms to adjust their 
portfolios to reduce capital requirements, perhaps without a 
commensurate reduction in risk. While the Board acknowledges this 
possibility, the Board expects that the principle of severity embraced 
in this framework will produce scenarios that adequately test such 
risks. Flexibility is maintained to allow scenarios to adapt to 
evolving conditions, not to reduce predictability and transparency. 
Indeed, the ranges of flexibility specified, especially when considered 
alongside the guidance offered regarding the conditions under which 
that flexibility might be employed, result in highly transparent and 
predictable scenario paths. Overall, the Board finds that the degree of 
flexibility and the goals of transparency and predictability are well 
balanced by this proposal, given the other requirements for designing 
effective and credible stress tests.
Summary of Scenario Design Principles
    In formulating the guides presented in this framework, the Board is 
proposing to continue to use a recession approach,

[[Page 51883]]

where the severely adverse scenario reflects conditions that 
characterize post-war U.S. recessions. To implement this approach, the 
Board adopts a specific scenario narrative in which a severe shock to 
financial markets propagates through the economy and results in a 
severe, prolonged recession most similar to that of the 2007-2009 
financial crisis. The Board provides a qualitative description of the 
scenario informing the hypothetical recession that the scenario 
reflects. In choosing specific scenario paths, the Board recognizes a 
need for the scenario to be adequately severe and credible, and to 
avoid adding to procyclicality.\118\ Finally, in this pursuit, the 
guides maintain a degree of flexibility to adapt to evolving economic 
and financial conditions. The Board continues to expect that there will 
be some important instances when it will be appropriate to augment the 
recession approach with salient risks and to set variables' values 
inside of, and in some cases, outside of the ranges and values provided 
in the guides in the Scenario Design Policy Statement.
---------------------------------------------------------------------------

    \118\ Assumptions that are meant to avoid adding procyclicality 
may add a degree of uncertainty to the path of the stress test 
scenario, relative to an assumption that is neutral to current 
economic conditions. However, the proposed variable guides and the 
model used to design the macroeconomic scenario would promote the 
predictability of the scenario and would help reduce year-to-year 
volatility of the stress test and the resulting capital 
requirements. This flexibility is particularly useful for the Board 
when the economy enters a recession and the credit quality of the 
banks' borrowers deteriorates, because a less-flexible scenario 
design framework could result in a significantly larger increase in 
capital requirements and hence a further drag on economic activity 
relative to the previous year than would the proposed framework.
---------------------------------------------------------------------------

    Question 41: What are the advantages and disadvantages of selecting 
the scenario design principles described in this section? Are there 
other principles that the Board should weigh along with these 
principles? Should the Board develop guidance for how it would weigh 
these principles in selecting values in annual scenario narratives?
    Question 42: What considerations should the Board evaluate when 
determining whether to set a given scenario variable independently of 
other variables in the annual scenario, or at similar levels of 
severity across multiple variables?
    Common Components of Scenario Path Guides
    The guides in this framework set out paths for each variable over 
the 13 quarters in the severely adverse scenario. The stress test 
requires projections of 13 quarters worth of losses to determine 
capital ratios at the end of 9 quarters of the scenario, because loss 
provisions in quarter 9 are affected by firm performance in quarters 10 
to 13. To describe these paths, most guides adopt a simple framework 
involving the following four parameters: the jump-off; the peak or 
trough; the timing of the peak or trough; and the trajectory from jump-
off to peak or trough. The purpose of publishing these components is to 
increase the transparency and public accountability of the stress test 
scenario by communicating how the variable would behave throughout the 
scenario period. In calibrating these parameters, the guides explain 
their rationale in applying the recession approach along with the 
scenario narrative and the three principles for scenario design 
described above. These parameters are described as follows:
    Jump-off: Jump-off values are important for informing the overall 
state of the economy in the scenarios, often affecting the specific 
levels achieved by the other parameters of the variable guide and 
informing the exercise of flexibility as specified in the guides. In 
the scenario, the jump-off value is the value of the variable in the 
quarter preceding the scenario. For most variables, the jump-off value 
is easily determined from published data at the time the scenario is 
released to the public. However, for some variables the jump-off value 
is not available prior to the date that the Board must finalize the 
annual scenarios for publication, so an estimate is used; these details 
are described in the individual guides. A separate issue involves 
choosing the appropriate historical jump-off date in the Board's 
analysis underlying the calibration of the guides. In many cases, 
stresses developed over time and a specific jump-off date or quarter 
for a particular period of stress may not be clearly identifiable. For 
instance, the 2007-2009 financial crisis had multiple newsworthy 
events--the suspension of redemptions from money market mutual funds by 
BNP Paribas in August 2007, the failure of Bear Stearns in February 
2008, and the bankruptcy of Lehman Brothers in September 2008. 
Therefore, the Board uses a range of quarters around the beginning of 
an identified recession or period of market stress to determine the 
jump-off values. The Board determined that using the most extreme value 
of the variable in the four quarters before, and the first quarter of, 
the National Bureau of Economic Research (NBER) recession date or 
documented financial stress event as the starting point for the 
analysis supporting the calibration of the severity of the guides was 
most consistent with the Board's stress testing principle of 
conservatism. Each guide provides further details on selection of 
relevant reference periods.
    Peak or trough: The paths in the guide specify that each variable 
in the scenario will either increase or decrease from its jump-off 
value. If it increases, it will reach a maximum or peak value during 
the scenario. If it decreases, it will reach a minimum or trough value 
during the scenario. For example, during the scenario, unemployment 
initially increases to a peak value, while house prices decrease to a 
trough value. Each guide provides details on how the Board expects to 
determine the level of this peak or trough and the rationale for this 
determination. In general, more extreme values are more stressful, and 
the specific levels of the peak or trough often depend on the jump-off 
values in line with the principles of severity, credibility, and not 
adding to procyclicality.
    Trajectories from jump-off to peak or trough: This parameter 
describes the values between the jump-off and peak or trough with a 
straight line (linear) function, a nonlinear function, or by specifying 
the proportion of the change from jump-off to peak or trough that will 
obtain in each of the intervening quarters. Two further notes on 
trajectories: first, trajectories are frequently described as either 
frontloaded, meaning that larger changes occur earlier in the 
trajectory, or backloaded, meaning that larger changes occur later in 
the trajectory. Depending on the variable, frontloading and backloading 
affect the overall severity of the scenario by having stressful changes 
earlier or lasting longer. The individual guides discuss this issue. 
Second, while several of the guides specify precise mathematical 
formulas for trajectories, for example linear (straight line) 
trajectories, rounding conventions--such as rounding to the first 
decimal place--for the published scenario may result in small 
differences from the result specified by the underlying formula. These 
rounding conventions result in small changes to scenario variables that 
tend not to affect overall severity. Instead, such rounding conventions 
are meant to help simplify the communication of the scenario to the 
public.
    The Board also considered the appropriate trajectory of variables 
after they reach the peak or trough and the appropriate end value. This 
analysis confirmed that the range of end values used in past stress 
tests are generally supported by historical analysis combined with the 
stress testing

[[Page 51884]]

principle of conservatism. The end value describes the value of the 
variable in the last (13th) quarter of the scenario. In applying the 
recession approach to calibrating end-values, the Board considers the 
values of a variable within a 10-15 quarter window after the beginning 
of the recession or other identified financial stress event, instead of 
simply taking the value of the variable in the 13th quarter. This range 
of values allows the Board to better assess outliers or other 
interactions between the data and the annual scenario narrative than 
other calibration methods. This flexibility also helps accommodate 
choices that account for the highly variable lengths of historical 
recessions. The Board expects that for most variables determined by 
guides, the recovery trajectories between the peak or trough and end 
value typically should follow a roughly linear path that proportionally 
allocates the change across the relevant time remaining to the end of 
the scenario. A roughly linear recovery reflects a preference for 
simplicity and transparency. For variables determined by the Board's 
macroeconomic model for stress testing, the end values and related 
trajectory from the peak or trough generally will be determined by the 
model.
    Timing of peak or trough: The guides for each variable set out the 
quarter of the scenario in which the variable path reaches its peak or 
trough. Generally, these occur earlier for fast moving variables and 
later for slow moving variables. Depending on the variable, either 
earlier or later timing may be more stressful, and there may be some 
flexibility in the timing of the peak or trough.
    In developing this framework, the Board considered a number of 
alternative specifications, both for specific variables and for the 
overall approach. Some of these alternatives are described in greater 
detail within the discussion of each proposed guide in Section IX.G of 
this Supplementary Information.
    As described in the Scenario Design Policy Statement, the Board 
considered alternatives to the recession approach for the overall 
design of the severely adverse scenario, including a probabilistic 
approach. The probabilistic approach would construct a baseline 
forecast from a large-scale macroeconomic model and identify a scenario 
that would have a specific probabilistic likelihood, given the baseline 
forecast. The Board believes that, at this time, the recession approach 
is better suited for developing the severely adverse scenario than a 
probabilistic approach because it guarantees a recession of some 
specified severity. In contrast, the probabilistic approach requires 
the choice of an extreme tail outcome--relative to baseline--to 
characterize the severely adverse scenario (e.g., a five percent or a 
one percent tail outcome). In practice, this choice is difficult as 
adverse economic outcomes are typically thought of in terms of how 
variables evolve in an absolute sense rather than how far from the 
baseline they lie in the probability space. In this sense, a scenario 
featuring a recession may be somewhat clearer and more straightforward 
to communicate. Finally, the probabilistic approach relies on estimates 
of uncertainty around the baseline scenario and such estimates are in 
practice model-dependent.
    The Board also considered two types of alternative specifications 
for each of the guides. First, the Board considered a more-prescriptive 
approach, in which the guides set a typical peak or trough value and a 
specific quarter in which that value would obtain, usually either at 
the most severe end of the range specified in the proposed guide or at 
the mid-point of the range. A guide set at the most severe end of the 
range would be consistent with the principle of conservatism and 
provide a high degree of transparency and predictability. In contrast, 
the lack of flexibility in such a guide would reduce the ability of the 
Board to respond appropriately to risks that are apparent in relevant 
indicators of economic and financial conditions and could potentially 
add to procyclical forces during economic booms or stressful periods. A 
guide benchmarked to the midpoint of the range might not be credible 
during periods of high vulnerability, while still being too severe when 
stresses were already present.
    Second, the Board considered that guides could have larger ranges 
for the potential peak or trough values or the timing of the peak or 
trough than the proposed guides. Larger ranges would increase the 
Board's ability to capture risks that are apparent in relevant 
indicators of economic and financial conditions and to adjust to 
procyclical forces but would be less predictable and transparent. In 
general, the Board expects the lower end of the range chosen for the 
proposed guides to represent the least amount of stress that would be 
deemed credible, while the higher end of the ranges already reflects 
the most severe plausible realizations of the variable. The proposed 
ranges for the guides are benchmarked to historical experience while 
still providing some ability to move beyond the upper or lower end of 
the historical range if circumstances dictate. In consideration of 
these factors and the principles discussed above in this section, 
therefore, the Board expects that the disadvantages from the loss of 
transparency and predictability from guides with larger ranges 
generally would be larger than the advantages stemming from more 
flexibility in the wider ranges of such guides.
    In each case, the proposed and some specific examples of 
alternative guides are both discussed. While the Board views the 
alternative guides as reasonable, the proposed guides have significant 
advantages over the considered alternatives. However, the purpose of 
the alternative guide discussion is to invite comment on a reasonable 
alternative considered by the Board and to transparently lay out the 
Board's present decision making in not adopting it.
    Question 43: What are the advantages and disadvantages of the 
alternative guides? Should the Board consider adopting any of the 
alternative guides? What, if any, other guides should the Board 
consider in addition to the alternative guides considered?

G. Description of Variable Guides in the Severely Adverse Scenario

Unemployment Rate
    The stress test scenarios set out trajectories for several 
variables, including the unemployment rate of the civilian non-
institutional population aged 16 and over (unemployment rate).\119\ As 
described in the previous sections, the Board intends to use a 
recession approach to develop the severely adverse scenario. The most 
common features of recessions are increases in the unemployment rate 
and contractions in aggregate incomes and economic activity. For this 
and the following reasons, the Board intends to use the unemployment 
rate as the primary basis for specifying the severely adverse scenario. 
First, the unemployment rate is likely the most representative single 
summary indicator of adverse economic conditions. Second, in comparison 
to GDP, labor market data have traditionally featured more prominently 
than GDP in the set of indicators that the NBER reviews to inform its 
recession dates.\120\ Third and finally, the growth rate of potential 
output can cause the size of the decline

[[Page 51885]]

in GDP to vary between recessions. While changes in the unemployment 
rate can also vary over time due to demographic factors, this seems to 
have more limited implications over time relative to changes in 
potential output growth. The unemployment rate used in the severely 
adverse scenario will reflect an unemployment rate that has been 
observed in severe post-war U.S. recessions, measuring severity by 
changes in the unemployment rate and GDP.\121\
---------------------------------------------------------------------------

    \119\ The Board uses the quarterly average of seasonally 
adjusted monthly unemployment rates for the civilian, non-
institutional population aged 16 years and older series from the 
Bureau of Labor Statistics (series LNS14000000).
    \120\ More recently, a monthly measure of GDP has been added to 
the list of indicators.
    \121\ Even though all recessions feature increases in the 
unemployment rate and contractions in incomes and economic activity, 
the size of this change has varied over post-war U.S. recessions. 
Table 5 documents the variability in the depth of post-war U.S. 
recessions. There is no universal agreement on how to categorize 
recession severity. For the purposes of this guide, the following 
categorization is employed: Recessions where the decline in real GDP 
and the increase in the unemployment rate are less than 1.5 percent 
or 1.5 percentage points, respectively, are considered mild; 
recessions where the decline in real GDP is 2.5 percent or more, or 
the increase in the unemployment rate is 3 percentage points or 
more, are considered severe; all other recessions are considered 
moderate.
---------------------------------------------------------------------------

    The Board uses a quarterly average of the monthly unemployment rate 
data in the stress test scenarios. The Board uses a quarterly average 
of unemployment for several reasons. Unemployment and, importantly, 
related variables such as disposable income (discussed below) can 
feature volatility at higher frequencies unrelated to underlying market 
conditions (e.g., unexpected weather events or a baseline level of 
statistical variation in the survey responses); quarterly averages 
smooth out the volatility that is present at monthly frequencies. 
Overall, using quarterly averages strikes a balance between being 
sensitive enough to capture broader economic trends and stable enough 
to avoid overreaction to short-term fluctuations. The Scenario Design 
Policy Statement outlines certain information regarding the peak level 
and timing of the peak level of the unemployment rate for the severely 
adverse scenario.\122\ This proposed guide conforms with and expands on 
that statement, providing greater predictability, transparency, and 
specificity with regards to the trajectory to peak value. The remainder 
of this section is outlined as follows. An overview of the unemployment 
guide components is given in Table 4. This is followed by a reiteration 
of the Scenario Design Policy Statement which describes the peak 
component of the unemployment rate and its timing. After that, a 
discussion of the trajectory to peak value is provided.
---------------------------------------------------------------------------

    \122\ Peak level represents the maximum value achieved during 
the scenario.
---------------------------------------------------------------------------

    The purpose of publishing these components is to increase the 
predictability, public accountability, and transparency of the stress 
test scenario by communicating how the variable will behave throughout 
the scenario period.

a. Peak Value and Timing of Peak
    The Board is proposing to retain the guide established in the 
Scenario Design Policy Statement, with some additional explanations 
provided here. The Board anticipates that the severely adverse scenario 
will feature an unemployment rate that increases between 3 to 5 
percentage points from its initial level over the course of 6 to 8 
calendar quarters.\123\ The initial level will be set based on the 
conditions at the time that the scenario is designed. However, if a 3 
to 5 percentage point increase in the unemployment rate does not raise 
the level of the unemployment rate to at least 10 percent--the average 
level to which it has increased in severe recessions--the path of the 
unemployment rate in most cases will be specified so as to raise the 
unemployment rate to at least 10 percent.
---------------------------------------------------------------------------

    \123\ Six to eight quarters is the average number of quarters 
for which a severe recession lasts plus the average number of 
subsequent quarters over which the unemployment rate continues to 
rise. The variable length of the timeframe reflects the different 
paths to the peak unemployment rate depending on the severity of the 
scenario.
---------------------------------------------------------------------------

    This methodology is intended to generate scenarios that feature 
stressful outcomes but do not add to procyclicality in the financial 
system and macroeconomy.\124\ When the economy is in the early stages 
of a recovery, the unemployment rate in a baseline scenario generally 
trends downward, resulting in a larger difference between the path of 
the unemployment rate in the severely adverse scenario and the baseline 
scenario, resulting in a severely adverse scenario that is relatively 
more intense. Conversely, in a sustained strong expansion--when the 
unemployment rate may be below the level consistent with full 
employment--unemployment

[[Page 51887]]

in a baseline scenario generally trends upward, resulting in a smaller 
difference between the path of the unemployment rate in the severely 
adverse scenario and the baseline scenario, resulting in a severely 
adverse scenario that is relatively less intense. Historically, a 3 to 
5 percentage point increase in the unemployment rate is reflective of 
stressful conditions. As illustrated in Table 5, over the last half-
century, the U.S. economy has experienced five severe post-war 
recessions. In all of these recessions excluding COVID-19, the 
unemployment rate increased 3 to 5 percentage points, and in the three 
most recent of these recessions excluding COVID-19, the unemployment 
rate reached a level between 8 percent and 11 percent.\125\
---------------------------------------------------------------------------

    \124\ For a discussion on the benefits of adequate severity, 
see, e.g., Judge 2022, supra note 103. For a discussion on the 
benefits of avoiding adding sources of procyclicality to the 
financial system, see, e.g., D. Kohn & N. Liang, Understanding the 
Effects of the U.S. Stress Tests, Brookings Institute (Jul. 2019), 
https://www.brookings.edu/articles/understanding-the-effects-of-the-u-s-stress-tests/.
    \125\ The unemployment rate was 8 percent in 1975Q1, 11 percent 
in 1982Q4, and 9 percent in 2009Q2.
---------------------------------------------------------------------------

    Under this method, if the initial unemployment rate were low--as it 
would be after a sustained long expansion--the unemployment rate in the 
scenario would increase to a level as high as what has been seen in 
past severe recessions. However, if the initial unemployment rate were 
already high--as would be the case in the early stages of a recovery--
the unemployment rate would exhibit a change as large as what has been 
seen in past severe recessions.
    The Board expects that the typical increase in the unemployment 
rate in the severely adverse scenario will be about 4 percentage 
points. However, as discussed in Section IX.F of this Supplementary 
Information, the Board expects to calibrate the increase in 
unemployment based on its views of the status of cyclical systemic 
risk. More specifically, the Board would be more likely to set the 
unemployment rate at the higher end of the range if the Board expects 
that cyclical systemic risks are high (as it would be after a sustained 
long expansion), and alternatively would be more likely to set the 
unemployment rate to the lower end of the range if cyclical systemic 
risks are low (as it would be in the earlier stages of a recovery), 
provided doing so remained consistent with the goal of ensuring that 
firms were properly capitalized to withstand severe economic and 
financial conditions. This may result in a scenario that is slightly 
more intense than normal if the Board expects that cyclical systemic 
risks were increasing in a period of robust expansion.\126\
---------------------------------------------------------------------------

    \126\ Note, however, that the severity of the scenario would not 
reach an implausible level: even at the upper end of the range of 
unemployment-rate increases, the path of the unemployment rate would 
still be consistent with severe post-war U.S. recessions. However, 
historical values need not serve as a binding upper bound for the 
scenario peaks as discussed in the introductory section of this 
proposal.
---------------------------------------------------------------------------

    Conversely, it would also allow the Board to specify a scenario 
that is slightly less intense than normal in an environment where 
systemic risks appeared subdued, such as in the early stages of a 
recovery. This choice would consider that the scenario does not add 
unduly to remaining stress, thereby exacerbating the initial adverse 
shock, and it would be particularly appropriate if the Board judges 
that firms are already taking steps to reduce their risk--for instance, 
by potentially restricting lending to otherwise qualified borrowers. 
The Board expects that, in general, it would adopt a change in the 
unemployment rate of less than 4 percentage points when systemic risks 
are low or receding. This might be the case when, along with other 
factors, the unemployment rate at the start of the scenarios is 
elevated but the labor market is judged to be strengthening and higher-
than-usual credit losses stemming from previously elevated unemployment 
rates were already realized--or are in the process of being realized--
and thus removed from firms' balance sheets.\127\ However, even at the 
lower end of the range of unemployment-rate increases, the scenario 
would still be expected to feature an increase in the unemployment rate 
similar to what has been seen in about half of the severe recessions of 
the past 50 years.
---------------------------------------------------------------------------

    \127\ Evidence of a strengthening labor market could include 
declines in weekly initial claims for unemployment, a declining 
unemployment rate, steadily expanding nonfarm payroll employment, or 
improving labor force participation. Evidence that credit losses are 
being realized could include elevated charge-offs on loans and 
leases, loan-loss provisions in excess of gross charge-offs, or 
losses being realized in securities portfolios that include 
securities that are subject to credit risk.
---------------------------------------------------------------------------

    As indicated previously, if a 3 to 5 percentage point increase in 
the unemployment rate does not raise the level of the unemployment rate 
to 10 percent--the average level to which it has increased in severe 
recessions--the path of the unemployment rate will be specified so as 
to raise the unemployment rate to 10 percent. Setting a floor for the 
unemployment rate at 10 percent recognizes the fact that not only do 
cyclical systemic risks build up at financial intermediaries during 
robust expansions, but also that these risks are easily obscured by a 
buoyant environment.\128\
---------------------------------------------------------------------------

    \128\ See supra note 114.
---------------------------------------------------------------------------

    In setting the increase in the unemployment rate, the Board will 
consider the extent to which analysis by economists, supervisors, and 
financial market experts finds cyclical systemic risks to be elevated 
(but difficult to be captured more precisely in one of the scenario's 
other variables).\129\ In addition, the Board--in light of potential 
impending shocks to the economy and financial system--expects to also 
take into consideration the extent to which a scenario of some 
increased severity might be necessary for the results of the stress 
test and the associated supervisory actions to sustain public 
confidence in financial institutions. Some indicators that would inform 
the Board's decision would be the growth rate of real GDP and its 
trajectory in recent quarters as well as leading economic indicators, 
such as equity prices as these measures provide a broader perspective 
on the state and direction of the economy. Consistent with the Scenario 
Design Policy Statement, the Board is mindful of sources of 
procyclicality in the financial system and in designing the severely 
adverse scenario. While the Board designs the stress test scenarios to 
promote the proper capitalization of firms, the scenarios are not 
intended to serve as an explicit countercyclical offset to the 
financial system.\130\
---------------------------------------------------------------------------

    \130\ See 12 CFR 252, Appendix A.
---------------------------------------------------------------------------

Alternative Peak Guide Options
    In preparing this proposal, the Board considered a guide that would 
choose a peak level for unemployment that is 4 percentage points higher 
than the jump-off value or 10 percent, whichever is higher. This 
alternative has the advantage of being simpler, more predictable, and 
more transparent than the guide choice. The Board views this 
alternative guide to be less desirable as it is less flexible and may 
end up being inadequately severe. Furthermore, such lack of flexibility 
could potentially add to scenario procyclicality. For example, in 
periods with already highly elevated unemployment rates above 7 
percent, this alternative could result in unemployment rates of 
historically high levels at times when economic conditions were already 
depressed.
    Instead, the current guide, specifying the greater of an increase 
of 3 to 5 percentage points or 10 percent, acknowledges that the Board 
would be unlikely to consider larger changes in unemployment when its 
rate is already highly elevated. As discussed in Section IX.F of this 
Supplementary Information, when the underlying conditions are favorable 
and firm losses are low, firms may project these tendencies forward,

[[Page 51888]]

paving the way to take more risk.\131\ Similarly, as discussed 
previously, the ability to adjust elements that potentially add 
procyclicality can be a major benefit of stress tests.\132\

---------------------------------------------------------------------------

b. Trajectory to Peak
    The Board anticipates that the severely adverse scenario would 
feature a trajectory to the peak unemployment rate that initially 
increases quickly with slower incremental increases. The trajectory to 
peak will have a concave parabolic path starting from the value in the 
economy at the beginning of the scenario and reaching a peak at between 
6-8 quarters.\133\ This approach for the trajectory to peak reflects 
several considerations. First, this trajectory to peak features larger 
increases in unemployment in the early quarters of the scenario, 
reflecting a rapid and deep deterioration in labor market conditions, 
in line with the scenario narrative discussed above and consistent with 
the principle that the severely adverse scenario be highly stressful as 
a rapid increase gives firms less time to adapt to changes. Second, 
this trajectory to peak is consistent with theoretical economic models 
which often share the feature that the response of unemployment to a 
shock features initially large increases in unemployment with 
decreasing incremental changes up to the peak.\134\ Empirically, this 
general pattern can be seen, for example, in the impulse response 
function illustrated in the first panel of Figure 2 in the FEDS Note 
that evaluates empirical regularities in variable co-movement in stress 
test scenarios.\135\ Third, while all recessions have differences in 
their specific paths of the unemployment rate, a concave trajectory to 
peak is broadly consistent with the data from severe recessions. One 
indicator is to look at second differences, which are the change in 
changes, an approximation of the acceleration of a variable.\136\ 
Concave paths have negative second differences. The second differences 
of the unemployment rate are negative on average for severe recessions, 
indicating a generally concave path with decreasing changes up to the 
peak.
---------------------------------------------------------------------------

    \133\ A concave curve is one with the property that any straight 
line drawn between two points on the curve lies on or below the 
curve. A parabolic path is a curve, x(t), that can be written as: 
x(t) = a(t[caret]2) + b(t) + c for some constants a, b, and c. In 
this case, concavity implies a < 0. If x0 is the jump-off value, 
xpeak is the peak value, and tpeak is the peak quarter, then the 
parameters for the path are given by the following equations: a = 
(x0-xpeak)/tpeak\2\, b = 2*(xpeak-x0)/tpeak, and c = x0. Published 
scenario values may differ somewhat from this formula because of

    Finally, a trajectory with frontloading of increases in the 
unemployment rate has been a characteristic of all recent severely 
adverse scenarios, except for the second round of bank stress tests in 
September 2020.\137\
---------------------------------------------------------------------------

    \137\ This additional round of stress tests was performed due to 
the continued uncertainty from the COVID-19 event. As the scenarios 
were designed for the unique COVID-19 event, the Board does not 
anticipate future stress testing to closely follow this unique 
episode.
---------------------------------------------------------------------------

House Prices
    The stress test scenarios set out trajectories for several 
variables, including house prices as measured by the Price Index for 
Owner-Occupied Real Estate (HPI).\138\ The Scenario Design Policy 
Statement outlined information regarding the formulation of house 
prices in the severely adverse scenario. This guide conforms with and 
expands on that statement, providing further information on the data 
used in the construction of the house price path in the severely 
adverse scenario, including the timing of the trough value and the 
trajectory to the trough value.\139\

the scenario.
---------------------------------------------------------------------------

    Firms subject to the supervisory stress test have a substantial 
exposure to the residential real estate market.\140\ Given firms' 
direct exposures, and the broader impact of the housing sector on 
household balance sheets and the macroeconomy, the Board's methodology 
for supervisory stress tests incorporates house prices into a number of 
models.\141\ Moreover, house price build-ups sometimes precede episodes 
of banking stress, with a notable example being the 2007-2009 financial 
crisis. By incorporating house prices into macroeconomic scenarios, 
supervisory stress tests help ensure that firms subject to the stress 
test are prepared for a range of market outcomes, including periods of 
large declines in house prices directly affecting loan performance and 
firms' balance sheets. This helps maintain the overall stability and 
resilience of the financial system.

    \140\ Regarding the importance of house prices to insured 
depository institutions generally, in 2025Q1, mortgages and 
mortgage-backed securities comprised more than 20 percent of FDIC

Estate, 1-4 Family Residential Mortgages, plus Mortgage-backed 
Securities, divided by Total Assets. Table II-A: Aggregate Condition

2025), https://www.federalreserve.gov/publications/files/2025-june-supervisory-stress-test-methodology.pdf.
---------------------------------------------------------------------------

    The Board uses a quarterly average frequency for this data in the 
supervisory stress test scenario. Instead of using the monthly 
frequency at which the underlying data is available, the Board uses a 
quarterly average of house prices in the stress test scenario for 
several reasons. House prices and, importantly, related variables such 
as disposable income (discussed more below) can feature volatility at 
higher frequencies unrelated to underlying market conditions. For 
example, extreme weather can affect the demand for home purchases and 
employment during a particular month, and thus the prices paid in home 
transactions and income that month, notwithstanding market conditions. 
Therefore, quarterly averages smooth out month-to-month volatility. 
Overall, using quarterly averages strikes a balance between being 
sensitive enough to capture market trends and stable enough to avoid 
overreaction to short-term fluctuations in prices.
    In determining the appropriate level of scenario severity, the 
Board adheres to the scenario design principles discussed in Section 
IX.F of this Supplementary Information. While doing so, the Board also 
strives to avoid introducing additional sources of procyclicality into 
the financial system. In the context of house prices, these principles 
are applied in calibrating the key aspects of the guide: the trough 
value, the timing of the trough value, and the trajectory to trough 
value. This approach helps ensure that the house price guide aligns 
with the established stress testing literature while mitigating 
potential systemic risks for the financial system. This guide 
description is outlined as follows. An overview of the house prices 
guide is given in Table 6. This is followed by a reiteration of the 
Scenario Design Policy Statement which describes the trough value used 
in the

construction of house prices. After that, this guide provides a 
supplementary discussion of the construction of house prices in the 
severely adverse scenario, followed by a discussion of the other 
components of the trajectory of house prices.

a. Trough Value Component of the Guide
    The Board is proposing to retain the guide established in the 
Scenario Design Policy Statement to inform the trough of house prices 
in the scenario, with additional explanations provided here. In most 
circumstances, the Board expects that the ratio of HPI to nominal per 
capita DPI (HPI-DPI ratio) falls by at least 25 percent or enough to 
bring the ratio down to the trough reached in the wake of the 2007-2009 
financial crisis, which occurred in the first quarter of 2012, 
whichever is greater.
Data- and Scenario-Based Rationale for the Trough Value
    Declining house prices, which are an important source of stress to 
a firm's balance sheet, are not a steadfast feature of recessions, and 
the historical relationship of national house prices with the 
unemployment rate is not strong. Simply adopting their typical path in 
a severe recession would likely underestimate risks stemming from the 
housing sector. This can be seen when considering regional housing 
recessions, which have occurred with greater frequency. Three examples 
include New England and California in the early 1990s, and Texas in the 
1980s. While regional house price indices featured only moderate 
decreases, the ratios of price to income fell precipitously. Further, 
in each case, the regional housing recession precipitated a regional 
banking crisis.\142\
    Assessing the procyclicality of house price paths over time is 
complicated by the fact that house prices--in contrast to the 
unemployment rate--have historically trended upward over time. 
Therefore, instead of specifying the path of house prices directly, the 
Board expects to consider the ratio of the nominal HPI to nominal per 
capita DPI. The HPI-DPI ratio does not exhibit an upward trend and, as 
such, provides an alternative way to assess the procyclicality of the 
scenarios' house price paths. Moreover, the HPI-DPI ratio is a commonly 
used valuation metric for the housing sector.\143\
---------------------------------------------------------------------------

    \143\ While different authors have considered different measures 
of house prices or income, there is wide agreement in the literature 
that price to income ratios are an important gauge of the state of 
the housing market. On the long-run stability of housing expenditure 
shares, see M. Davis & F. Ortalo-Magn[eacute], Household 
Expenditures, Wages, Rents, 14 Rev. of Econ. Dynamics 248-261 
(2011). For an analysis of the importance of price-to-income ratios 
for mortgage delinquencies, see K. Gazi & C. Vojtech, Bank Failures, 
Capital Buffers, and Exposure to the Housing Market Bubble, 52 Real 
Estate Econ. 1470-1505 (2024). For a macroeconomic model and 
discussion, see C. Leung & E. Tang, The Dynamics of the House Price-
to-Income Ratio: Theory and Evidence, 41 Contemporary Econ. Policy 
61-78 (2023). Other references considering price-to-income ratios in 
financial stability include E. Pavlidis et al., Episodes of 
Exuberance in Housing Markets: in Search of the Smoking Gun, 53 The 
J. of Real Estate Fin. and Econ. 419-49 (2016); and K. Case & R. 
Shiller, Is there a Bubble in the Housing Market?, Brookings Papers 
on Economic Activity, No. 2003.2, 299-362 (2003).
---------------------------------------------------------------------------

    Under most circumstances, the Board expects the decline in the HPI-
DPI ratio in the severely adverse scenario to be 25 percent from its 
starting value or enough to bring the ratio down to its trough during 
the 2007-2009 financial crisis, whichever is the larger decline. The 
maximum trough level specified in this guide is motivated by the data, 
corresponding to the level achieved in the wake of the 2007-2009 
financial crisis, which reached a trough in the first quarter of 2012. 
The minimum decline specified in this guide for the HPI-DPI ratio from 
its starting value, a 25 percent decline,is motivated by the data as 
well--such a fall reflects the average peak to trough fall in this 
ratio across the three national housing recessions identified by the 
Board, as shown in Table 7.\144\ While the average across housing 
recessions is heavily influenced by the steep decline in the 2007-2009 
financial crisis, similar magnitude falls have occurred with greater 
frequency when considering the
---------------------------------------------------------------------------

    \144\ The national house-price retrenchments that occurred over 
the periods 1980-1985, 1989-1996, 2006-2011 are referred to in this 
document as housing recessions. The date ranges of housing 
recessions are based on the timing of house-price retrenchments. 
These dates were also associated with sustained declines in real 
residential investment, and the precise timings of housing 
recessions would likely be slightly different were they to be 
classified based on real residential investment in addition to house 
prices. The ratios described in Table 7 are calculated based on 
nominal HPI and HPI-DPI ratios indexed to 100 in 2000:Q1.

---------------------------------------------------------------------------

[[Page 51890]]

aforementioned regional housing recessions.\145\
---------------------------------------------------------------------------

    \145\ See infra note 148.
---------------------------------------------------------------------------

    The minimum decline of 25 percent ensures adequate scenario 
severity, maintaining the credibility of the stress test while at the 
same time constraining the trough from becoming unduly contractionary 
and deviating too far from historically observed levels.\146\ Applying 
a larger value of a minimum decline (e.g., the 2007-2009 peak-to-trough 
fall of more than 40 percent) could result in a trough level that is 
unjustifiably far away from most historical movements, especially if it 
were applied during a period in which the HPI-DPI ratio were already at 
a low level. Alternately, specifying a maximum trough level higher than 
that experienced during the 2007-2009 financial crisis might not allow 
the Board to adequately test firms' resilience to potential shocks when 
home valuations are as elevated as they were in the mid-2000s.
---------------------------------------------------------------------------

    \146\ If a future stress event causes the HPI-DPI to fall 
significantly below the 2007-2009 financial crisis trough, or 
perhaps just to that level, the Board will consider an update of the 
trough calibration to reflect that new empirical evidence in 
subsequent future tests.
---------------------------------------------------------------------------

    The construction of this part of the house prices guide reflects 
the goal of avoiding adding sources of procyclicality in the financial 
system. Accordingly, the severely adverse scenario will feature smaller 
variable movements when those variables are less extreme, and the 
severely adverse scenario will feature larger variable movements when 
those variables are more extreme, generally up to a level at least as 
extreme as the 2007-2009 financial crisis.
    The recession approach provides further justification for the 
proposed calibration of the severity of the trough of house prices. 
While national house prices and national unemployment do not exhibit a 
strong relationship in the data, research shows that unemployment in a 
household has a large effect on default rates, and that increases in 
local unemployment are correlated with decreases in local house 
prices.\147\ Similarly, regional housing recessions often feature 
increases in regional unemployment.\148\ Hence, the recession approach 
suggests that a scenario with a high peak level of unemployment should 
also feature a low nadir in house prices.

b. Additional Guide Parameters and Rationale
    This subsection begins with a description of the construction of 
the house price series. This is followed by a description of the timing 
of the trough of HPI-DPI. The subsection concludes with information 
regarding the trajectory to trough.
Construction of House Prices From HPI-DPI
    Unlike the guides for some other variables, such as unemployment 
and equity prices, this guide does not directly specify a path for 
house prices in the severely adverse scenario. Instead, this guide 
specifies a path for the HPI-DPI ratio. The scenario projection for 
house prices is then calculated from this ratio using paths for DPI and 
population, as calculated by the macroeconomic model for stress testing 
that the Board has developed specifically to aid in communicating the 
stress test scenario to the public specified on the Board's website. 
The scenario projection for population is the same as that contemplated 
in the Baseline Scenario Guide, as described in Section IX.C of this 
Supplementary Information and in section 4.1 of the Scenario Design 
Policy Statement. The scenario projection for house prices is then 
calculated as the HPI-DPI path, discussed in this guide, multiplied by 
nominal disposable income divided by population.
Trough Value Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The Board expects that the trough of HPI-DPI typically should occur 
between quarter 8 and quarter 10 of the severely adverse scenario, as 
explained below.
    To support this range for the timing of the trough in house prices, 
the Board applied the recession approach and used the timing of 
unemployment peaks to calibrate the timing of the trough of HPI-DPI. 
This benchmarking to the unemployment peak was necessary because house 
prices have more protracted cyclical dynamics than other scenario 
variables described in this framework. The three major house price 
retrenchments indicated in Table 7 featured peak-to-trough durations 
for HPI-DPI of between 19 and 30 quarters. The full implications of 
such a protracted decline cannot be adequately assessed by including 
only a portion of that decline within the nine-quarter horizon of the 
annual stress tests, because the resilience of firms would be impacted 
importantly by investors' perceptions of the expected future

[[Page 51891]]

losses.\149\ Moreover, the practical difficulties presented by the 
difference between the length of historical housing cycles and the 
length of the stress test scenario is an example of why the Board 
expects to maintain the flexibility to use scenarios that are not 
exactly like historical scenarios.\150\ Together, these two notions, 
one practical and the other principled, require the Board to consider a 
more careful approach to reading the historical record in its 
determination of the timing of the trough value for HPI-DPI.
---------------------------------------------------------------------------

    \149\ Supervisory stress tests consider results from the nine 
quarters following the jump-off quarter. This and other guides 
specify a 13-quarter path because the calculation of provisions for 
losses are forward looking; that is, they depend on estimated losses 
in the subsequent four quarters. Therefore, they require values for 
some macroeconomic variables to extend beyond the nine quarters that 
are counted in the stress test.
    \150\ See Schuermann (2014), supra note 99.
---------------------------------------------------------------------------

    Because the length of the severely adverse scenario cannot 
replicate the duration of historical housing recessions, the Board 
identified the subperiods within past housing recessions that featured 
the greatest declines in HPI-DPI to support its calibration of the 
trough within the scenario. This choice reflects the principle of 
severity. The Board considered three window lengths when calculating 
periods of maximum declines in HPI-DPI: 6, 9, and 13 quarters.\151\ The 
calculations in Table 7 include the trough-quarter of such windows, 
along with the percentage decline in HPI-DPI over each window.
---------------------------------------------------------------------------

    \151\ These three window lengths were considered as they span 
the set that would satisfy the limited duration of the scenario and 
the need for severity discussed above.
---------------------------------------------------------------------------

    Under the recession approach, the Board calibrates other variables 
to be consistent with the scenario path for unemployment. To compare 
the maximum decline in the HPI-DPI ratio with the peak in unemployment, 
the table also includes the timing of the peak quarter for unemployment 
along with the difference in timing between the peak unemployment rate 
and the end of the window. For example, when considering the period 
2005Q4-2012Q1 (Column 3, Table 8), the 6-quarter window with the 
greatest change in HPI-DPI is 2007Q2-2008Q4 (Row 2, Column 3). This 
window featured a fall in the HPI-DPI ratio of 24.1 percent. The end of 
this window, 2008Q4 is 4 quarters before the unemployment rate peaked 
in 2009Q4.
    On average, the quarter of the maximum decline in HPI-DPI over 6-
quarter windows precedes the quarter of peak unemployment by 1.67 
quarters. The unemployment guide features a range for the peak in 
unemployment with a midpoint in quarter 7. Therefore, to be consistent 
with some years' contemplated path for unemployment, a 6-quarter window 
for the decline in HPI-DPI would have to start with the scenario jump-
off quarter rather than the first quarter of the scenario. Hence, the 
Board deemed a trough timing for HPI-DPI of 6 quarters as too short.
    More promisingly, the relationship between the peak of unemployment 
and the trough of the HPI-DPI ratio flips at longer horizons. The 
unemployment peak quarter precedes the quarter of the maximum declines 
in HPI-DPI over 9 and 13 quarter windows by an average of 0.67 and 
2.33, respectively. Therefore, trough timings of both 9 and 13 quarters 
would be broadly consistent with the length of the scenario and the 
timing of the unemployment peak within it. Of these two options, the 
Board deems that the trough timing of HPI-DPI should occur around 
quarter 9 for two auxiliary reasons: First, an interior trough time 
allows for some subsequent recovery, mirroring the movement of 
unemployment and other variables in this framework. Second, a shorter 
duration to trough, all else equal, will result in a more severe 
scenario, consistent with the principal of conservatism.
    In addition, the maximum changes in HPI-DPI for the 6, 9, and 13 
quarter subperiods associated with the 2007-2009 financial crisis are 
close to or larger than 25 percent. Hence, this subperiod analysis also 
further supports the calibration of the trough level in this guide.
    Turning to a comparison with past scenarios, the selection of a 
range of quarter 8 to 10 for the trough of HPI-DPI in the severely 
adverse scenario is broadly consistent with the timing of past 
scenarios. In 2019 to 2022, the severely adverse scenario featured a 
trough in quarter 9. In 2023 to 2025, the severely adverse scenario 
featured a trough in quarter 7, as the Board assessed valuation 
pressures in residential real estate to be very elevated and wanted to 
ensure that the banking system remained resilient to a sudden 
correction in the housing market. Although that calibration of the 
guide would require the Board to explain its rationale for choosing an 
earlier trough going forward, the analysis presented above about the 
typical timing of house price troughs suggests that a trough between 
quarters 8 and 10 of the scenario usually would be sufficiently and 
credibly stressful. In choosing the timing of the trough, the Board 
expects to choose an earlier trough when the level of systemic risks is 
high or rising and a later trough when the level of systemic risks is 
low or declining. Housing market indicators such as recent trends in 
HPI-to-DPI ratios, house price growth, the growth rate of mortgage 
lending, or changes in mortgage lending standards are factors in that 
determination. Conversely, when vulnerabilities or risks related to 
residential real estate and related lending are low or decreasing, the 
Board could consider a later trough.

Trajectory to Trough
    This guide specifies a trajectory to trough featuring 20 percent of 
the decline in the first quarter, 20 percent of the decline in the 
second quarter, and a linear trajectory to trough thereafter, subject 
to the rounding conventions mentioned in Section IX.F of this 
Supplementary Information. As shown in Table 8, housing recessions tend 
to be protracted. While the Board follows the recession approach, the 
other principles from the stress testing literature suggest that a 
careful reading of the data is warranted. To this end, when considering 
the windows with the most rapid declines in Table 8 above, further 
analysis shows that each housing recession featured quarters with 
declines near 20 percent. In an application of the principle of 
conservatism, the Board finds that two quarters of 20 percent declines 
broadly fits the scenario narrative of a rapid decline in economic 
conditions and sentiment, while meeting the other principles set out in 
this guide; frontloaded declines are relatively more severe, so are 
consistent with the principles of conservatism, severity, and the need 
to consider possibilities somewhat outside the historical evidence. The 
specification of linear declines thereafter was chosen in the interest 
of simplicity.

Reserve Board; (3) Federal Reserve staff calculations.
---------------------------------------------------------------------------

    Moreover, a rapid decline in house prices is consistent with the 
recession approach, in which other variables in the scenario are guided 
by the scenario trajectory for the unemployment rate, which features 
rapid initial deterioration. In addition, rather than having HPI-DPI 
decline throughout the 13 quarter scenario as might be justified given 
the historical record, the Board expects that house prices in the 
severely adverse scenario will feature a moderate recovery after their 
trough--again, consistent with the recession approach where variables 
follow from the general movements of the unemployment rate, which 
itself recovers after its trough--a feature which moderates the 
severity of the initial decreases in house prices. Turning to past 
scenarios, a moderately frontloaded trajectory to trough strikes a 
balance between recent scenarios. Scenarios from 2023 to 2025 featured 
strongly frontloaded declines, with more than 40 percent of the drop 
happening in the first quarter, and increasingly smaller drops to the 
trough. Frontloading the decline in this manner is consistent with the 
principle of conservatism and the advice from stress testing literature 
to consider features that are outside of historical experience when 
vulnerabilities are elevated. The Board made a different decision with 
house price scenarios in 2021 and 2022, which featured a less stressful 
trajectory of initially small declines followed by a

[[Page 51893]]

period of larger declines while the economy was recovering from the 
COVID-19 recession. Hence, a moderately frontloaded trajectory falls 
between these earlier and later scenarios. The Board sees the reduction 
in flexibility in this component of the house price path as partially 
offset by the additional predictability and simplification that it 
provides.
    The Board expects that a scenario consistent with the level, 
timing, and trajectory to the trough of house prices specified by this 
guide will be at least somewhat more severe than the average of past 
housing recessions and sufficiently close to the house price correction 
associated with the 2007-2009 financial crisis.
Commercial Real Estate Prices
    The stress test scenarios set out trajectories for several 
variables, including commercial real estate prices as reported in the 
Board's Z.1 statistical release.\153\ The Commercial Real Estate Price 
Index aggregates price indices across office, retail, industrial and 
other types of properties.
---------------------------------------------------------------------------

    \153\ The source for the data is the Commercial Real Estate 
Price Index, Z.1 Release (Financial Accounts of the United States), 
Federal Reserve Board. This index is based on quarterly change of 
the Value Weighted Costar U.S. Composite Index Excluding 
Multifamily.
---------------------------------------------------------------------------

    In the supervisory stress test, commercial real estate prices 
capture a key part of the risks to firms from their commercial real 
estate exposures, which are reported by firms on FR Y-14Q, Schedule 
H.2. Most firms subject to the supervisory stress test have a 
substantial exposure to the commercial real estate market. Moreover, 
commercial real estate price build-ups often precede episodes of market 
stress. By incorporating commercial real estate prices into 
macroeconomic scenarios, supervisory stress tests help ensure that 
firms subject to the stress test are prepared for a range of market 
conditions, including periods of large decline in commercial real 
estate prices directly affecting the firms' balance sheets. This helps 
maintain the overall stability and resilience of the financial system.
    In determining the appropriate level of scenario severity, the 
Board adheres to the scenario design principles discussed in the 
earlier Section IX.F of this Supplementary Information. While doing so, 
the Board also strives to avoid introducing additional sources of 
procyclicality into the financial system. In the context of commercial 
real estate prices, these principles are applied in calibrating three 
key aspects of the guide: the trough value, the timing of the trough 
value, and the trajectory to trough value. This approach ensures that 
the commercial real estate price guide aligns with the established 
stress testing literature while mitigating potential systemic risks for 
the financial system.
    The rest of this section is organized as follows. First, Table 9 
includes an overview of the Board's proposed guide for setting 
commercial real estate prices in the severely adverse scenario. The 
next subsection provides the data- and scenario-based rationale for the 
calibration of the trough component. Afterward follows a discussion of 
the alternative trough option, comparing the implementation and caveats 
to the proposed guide description. Finally, additional guide parameters 
for the trough timing and trajectory to trough value, and the rationale 
for their calibration are discussed.

a. Trough Value Component of the Guide
    The proposed guide stipulates that at the trough, commercial real 
estate prices will drop between 30 percent and 45 percent from the 
jump-off value. The choice of the specific magnitude of drop within 
this range will be determined based on the overall level of cyclical 
systemic risk and an assessment of relevant indicators in the market as 
reflected by a range of commercial real estate indicators such as the 
level and change over preceding years in commercial real estate prices, 
commercial real estate capitalization rate (cap rate), lending 
standards on commercial real estate loans, rents, and vacancy rates, 
among other indicators. The Board generally judges valuation pressures 
and the implied level of risk by looking at where recent observations 
of these relevant indicators are within their distributions.
Data- and Scenario-Based Rationale for the Trough Value
    In line with the scenario design principles for setting the 
scenario severity, as discussed earlier in Section IX.F of this 
Supplementary Information, the proposed guide takes into account the 
dynamics of a variety of commercial real estate market indicators, 
including but not limited to the growth rates of commercial real estate 
prices, changes in bank lending standards in the commercial real estate 
segment, and the commercial real estate capitalization rate over the 
past several years. The consideration of several years of history for 
this variable is due to the slower-moving nature of commercial real 
estate markets, in contrast with market volatility (measured by the 
Chicago Board Options Exchange's CBOE Volatility Index (VIX)), stock 
market prices, and corporate bond spreads, as described in those guides 
below. The long-lived nature of these assets and substantial upfront 
financial investment involved can loosen the connections between their 
current observed valuations and financial conditions at firms and in 
broader financial markets. For instance, lending practices adopted in a 
period of declining prices, such as 2023 and 2024, can cloud immediate 
price signals. Additionally, the complexity of these connections and 
the

[[Page 51894]]

breadth of property types make it difficult to track developments in 
the commercial real estate sector with a single quantitative indicator 
or a very limited set of indicators that would constitute a basis for 
the commercial real estate guidance. Therefore, the proposed guide 
establishes a range of price decline values that determine the 
magnitude of the price decline to the trough, as well as its 
characteristics.
    The proposed calibration of the range of decline (30 to 45 percent) 
to the trough for the commercial real estate price index is determined 
to account for commercial real estate price behavior in severe post-war 
U.S. recessions and to allow for increases in severity after economic 
expansions, in line with the principles outlined in the policy 
statement as well as those discussed earlier in this section. First, 
the range is centered around the value observed during the 2007-2009 
financial crisis, when commercial real estate prices dropped about 39 
percent from the peak in 2007Q3 to the trough in 2009Q4 (Table 10). 
Second, the extent of commercial real estate price upswings provides a 
guide for their subsequent unwinding and another target for the range. 
As mentioned in the Board's policy statement, cyclical vulnerabilities 
rise during more robust expansions. Looking back at the most recent 
commercial real estate cycle upswing in 2013-2024, the median four-year 
commercial real estate price growth rate in this period is about 30 
percent, which the Board uses to calibrate the lower part of the range. 
Setting a floor for the decline in commercial real estate prices of 30 
percent recognizes the fact that, not only do cyclical systemic risks 
build up at financial intermediaries during robust expansions, but also 
a minimum level of risk exists even in an already stressed environment. 
Separately, the Board opts for 45 percent as the higher end of the 
range, as a similar value (43 percent, as measured by the four-year 
growth rate of the commercial real estate price index between 2011Q3 to 
2015Q3) was observed in the 2013-2024 commercial real estate cycle. The 
upper end of this range is also set to be larger than the 39 percent 
decrease experienced during the 2007-2009 financial crisis to allow for 
scenarios that feature commercial real estate price declines that are 
larger than what have been seen historically. Adequate severity 
requires a guide to be able to go somewhat beyond historical 
experiences when initial conditions warrant. Furthermore, certain 
sectors within the commercial real estate market have already 
experienced larger declines than 39 percent in the post-COVID-19 
period, further justifying a range of potential declines that can 
address risks that are apparent in relevant indicators of economic and 
financial conditions as they arise.

    In its formulation of the annual scenarios, the Board could 
consider the overall level of cyclical systemic risk or various 
indicators related to commercial real estate markets to determine the 
appropriate decline in commercial real estate prices in the scenario. 
As discussed in Section IX.F of this Supplementary Information, the 
Board expects to calibrate the decline in commercial real estate prices 
based on its views of the status of cyclical systemic risk.

(series FL075035503.Q divided by 1000).
---------------------------------------------------------------------------

    Specifically, the Board would be more likely to set the commercial 
real estate price trough value at the higher end of the range if the 
Board expects that cyclical systemic risks are high (as it would be 
after a sustained long expansion), and alternatively would be more 
likely to set the trough value to the lower end of the range if 
cyclical systemic risks are low (as it would be in the earlier stages 
of a recovery), provided doing so remained consistent with the goal of 
ensuring that firms were properly capitalized to withstand severe 
economic and financial conditions. This may result in a scenario that 
is more intense than normal if the Board expects that cyclical systemic 
risks were increasing in a period of sustained robust expansion.
    Conversely, it would also allow the Board to specify a scenario 
that is less intense than normal in an environment where systemic risks 
appeared subdued, such as in the early stages of an expansion. This 
choice would consider that the scenario does not add unduly to 
remaining stress, thereby exacerbating the initial adverse shock, and 
it would be particularly appropriate if the Board judges that firms are 
already taking steps to reduce their risk--for instance, by potentially 
restricting lending to otherwise qualified borrowers. Factors such as 
whether underlying commercial real estate market conditions have 
started to normalize and higher-than-usual credit losses stemming from 
previous commercial real estate price declines were either already 
realized--or are in the process of being realized--and thus removed 
from firms' balance sheets would contribute to the assessment of 
cyclical systemic risks.\155\
---------------------------------------------------------------------------

    \155\ A commercial real estate market normalization could occur 
when lending standards stop tightening, commercial real estate price 
levels stabilize, and the capitalization rate moves toward the 
middle of its historical range or higher. Evidence that credit 
losses are being realized could include elevated charge-offs on 
loans and leases or loan-loss provisions in excess of gross charge-
offs.
---------------------------------------------------------------------------

    Figure 1 illustrates how the proposed guide (range between solid 
lines) performs compared to past scenarios (shown as dots). As seen in 
this figure, the proposed guide fully brackets the declines featured in 
previous scenarios. Thus, the proposed guide is likely to result in 
similar stress test severity as

before this revision to the policy statement.

Alternative Trough Guide Option
    The Board considered an alternative trough option in which 
commercial real estate prices fall 35 percent from the jump-off value, 
or reversal of prior 4 years of price increases up to 45 percent, 
whichever results in a larger decline. The calibration of the 
alternative guide relies on the similar observations shown in Table 10 
and used for the calibration of the proposed guide. Specifically, the 
alternative guide caps the decline in the commercial real estate prices 
to a range between 35 and 45 percent. However, to determine the 
specific decline in this range, in contrast to the proposed guide which 
considers a variety of commercial real estate-market indicators and 
allows for weighing them against each other, this alternative focuses 
on only one dimension of potential risks in the commercial real estate 
market--price pressures accumulated over the previous 4 years--and 
formalizes the decline to the trough based on this indicator.
---------------------------------------------------------------------------

    \156\ Z.1 Release (Financial Accounts of the United States), 
Federal Reserve Board; Federal Reserve staff estimates.
---------------------------------------------------------------------------

    The alternative guide stipulates that commercial real estate prices 
will decline to the trough from the jump-off value by 35 percent or by 
an amount needed to offset the four-year commercial real estate price 
growth preceding the jump-off quarter. Hence, the alternative minimum 
decline could be somewhat more severe compared to the proposed guide. 
That said, the decline is capped at 45 percent to constrain the trough 
calibration within historically plausible bounds. The choice of four 
years (rather than, for example, the one-year look back used in the 
equity price guide) to span the relevant accumulation period of price 
pressures for this guide stems from a slower-moving nature of the 
commercial real estate cycle, in contrast to faster moving variables 
(like VIX or stock prices). At the same time, choosing a longer look-
back time period, such as five years, for example, would often produce 
commercial real estate growth rates above 45 percent, thus triggering 
the 45 percent maximum threshold of the guide too frequently and 
resulting in excessive scenario severity relative to historically 
observed events, particularly at the beginning of market 
corrections.\157\
---------------------------------------------------------------------------

    \157\ In the 2014-2024 period, for example, 5-year growth rates 
above 45 percent occur in 2014Q4, 2015Q1, 2016Q3, 2016Q4, 2017Q1.
---------------------------------------------------------------------------

    The commercial real estate price troughs set in past annual stress 
test scenarios and the prescription of the alternative guide could be 
noticeably different. In the data, previous commercial real estate 
price changes in annual stress test scenarios, the key factor in 
determining the prescription for the alternative guide, are not always 
highly correlated with other commercial real estate indicators that the 
Board would have used to gauge the extent of salient risks at the time.
    For instance, from 2021-2023 (post-COVID-19 pandemic) the 
alternative guide would prescribe troughs at 35 percent below jump-off 
values, while the proposed guide would prescribe troughs similar to 
those of past scenarios, around 40 percent below jump-off. The 
alternative guide thus would not have accounted for the unusually small 
number of commercial real estate sales that occurred during that period 
and the upward biases in transaction-based commercial real estate

[[Page 51896]]

price indices created by the strategic behavior of owners, lenders, and 
buyers in those conditions.\158\ Once commercial real estate prices had 
declined considerably by 2024 and transaction volumes increased, the 
shallower trough calibration for this alternative guide aligns with the 
Board's choice for the severely adverse scenario.\159\ This example 
illustrates that focusing on only one quantitative indicator (four-year 
commercial real estate price growth) may be too narrow to determine an 
adequate severity for the magnitude of decline from the start of the 
stress test scenario to its trough (i.e., start-to-trough decline) for 
this variable.

---------------------------------------------------------------------------

    Therefore, a guide that weighs a broader range of indicators and 
how conditions differ by property type could provide a fuller, more 
adequate framework for the Board to choose an appropriate level of 
stress for commercial real estate exposures in future stress test 
scenarios. Consequently, the Board would consider the overall level of 
cyclical systemic risk, which is informed by a range of indicators 
related to commercial real estate markets, in its formulation of the 
annual scenarios as discussed in this section.
    Although the proposed and the alternative guides are both 
discussed, and the Board views the alternative guide as reasonable, it 
may be insufficient to capture the complexity of the commercial real 
estate market relative to the proposed guide. In addition, the 
implementation of the alternative guide for commercial real estate 
would be complicated by the lack of a real-time commercial real estate 
price indicator. Typically, the data are available with a 4-month lag, 
which means that the final quarter or two of data required to compute 
the value of the guide would be based on a projection rather than 
reported data. The purpose of the alternative guide discussion is to 
invite comment on a reasonable alternative considered by the Board and 
to transparently lay out the Board's present arguments for choosing the 
proposed guide.
b. Additional Guide Parameters and Rationale Behind Them
Trough Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the trough and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The Board considers the 
dynamics of commercial real estate prices using the official NBER 
recession dates augmented by one year prior to the beginning of the 
recession and one year after the end of the recession to compute 
summary statistics for validating the timing of the trough for 
commercial real estate prices in this guide. The Board considers such 
additional data points because of the slow-moving nature of the 
commercial real estate cycles, as referenced earlier in this section, 
in comparison with the fast-moving and forward-looking behavior of 
equity prices, corporate bond spreads, and VIX, for which the moves 
following the Lehman Brothers bankruptcy during the 2007-2009 financial 
crisis are most consistent with the scenario narrative adopted in this 
proposed policy statement.
    The guide stipulates that the trough level in the scenario would be 
reached in quarters 8 to 10. This range is consistent with the slower-
moving nature of commercial real estate price cycles, the practice in 
previous severely adverse scenarios, and the behavior in previous 
periods of financial stress or recession. In the stress episode 
surrounding the 2007-2009 financial crisis, the commercial real estate 
price trough was in quarter 9 (Table 10). The usual process of slow 
adjustment of commercial real estate prices and the ambiguity in the 
measurement of those prices described earlier in this section motivates 
the Board to reserve a range in which the adjustment occurs. Keeping 
the magnitude of the trough constant, a more delayed trough timing 
generally results in less severity of the overall path, as a less 
abrupt worsening in conditions and credit quality gives firms more time 
to adjust to the shock. Thus, a range in the timing (quarter 8 to 10) 
is an additional lever (together with the trough magnitude range) to 
avoiding the addition of sources of procyclicality in the stress test. 
The Board would likely consider a delayed timing of the trough when the 
cyclical vulnerabilities are lower, and an earlier trough timing when 
the Board deems it appropriate to increase scenario severity, as 
described in this section in relation to the choice of price decline.
Trajectory to Trough Value
    To reach the trough value, the guide prescribes a smooth roughly-
linear transition from the jump-off point to the trough. This 
prescription is consistent with the linear models often used in the 
statistical modeling of macroeconomic series.\160\ Commercial real 
estate prices are slower-moving, even in crisis times, so there is less 
evidence of the frontloading seen in faster-moving variables such as 
the VIX or BBB spreads. Moreover, the breadth of property types and 
lags in real-time data availability contribute to the difficulty of 
tracking the developments in this sector. As discussed above, 
transactions-based prices may have biases based on the strategic 
behavior of the parties involved. Given these circumstances, 
considering more complicated trajectories may inject unnecessary 
volatility into the exercise, counter to the principles laid out on 
effective stress testing in Quarles (2019).\161\

---------------------------------------------------------------------------

    The trajectories prescribed in previous scenarios are consistent 
with the proposed guidance that commercial real estate price declines 
are not frontloaded. The two exceptions are for the scenarios during 
2017 and 2018, where the largest declines occur in the second quarter 
of the scenario. In these years' scenarios, to test the resilience of 
the banking system to strong economic conditions and commercial real 
estate price increases in prior years, the Board chose scenarios which 
called for deeper and earlier declines in commercial real estate prices 
than considered in prior years' stress test scenarios. Notwithstanding 
these exceptions, the smoother decline specified by the proposed guide 
is more in line with historical behavior of the series and has the 
benefit of reducing volatility.
Equity Prices
    The stress test scenarios set out trajectories for several 
variables, including equity prices proxied by the U.S. Dow Jones Total 
Stock Market

[[Page 51897]]

Index (DWCF).\162\ This index includes about 3,700 stocks trading on 
U.S. exchanges that account for 95 percent of the total market 
capitalization.
    Along with commercial real estate prices, housing prices, and the 
VIX, equity prices are an essential gauge for asset prices that affect 
the U.S. economy and the financial conditions of financial and 
nonfinancial firms. Equity prices are generally recognized as a leading 
indicator of future economic conditions broadly, including economic 
growth and inflation.\163\ Therefore, testing the ability of a firm to 
withstand a steep decline in equity prices helps ensure that these 
firms are properly capitalized to withstand severe economic and 
financial conditions.
    In the supervisory stress test scenarios, equity prices are 
converted to quarterly frequency using the quarter-end value. The 
Board's use of this aggregation method in the severely adverse 
scenario, rather than average or maximum value in the quarter used for 
other variables, is a deliberate choice that reflects how equity prices 
might impact the balance sheets of financial institutions. Quarter-end 
values provide a clear, specific point-in-time snapshot of market 
conditions, which is crucial for assessing firms' balance sheets and 
market risk exposures. For trading books and fair-value estimates for 
assets that firms hold, quarter-end prices provide the most up-to-date 
mark-to-market valuation, which is critical for stress testing. Equity 
markets are typically more liquid than debt markets or markets for real 
estate, which means the most recent prices are less likely to be 
affected by technical factors instead of economic fundamentals and 
expectations about future conditions than in bonds or property markets. 
Using quarter-end values also makes it easier to compare stress 
scenarios with historical data, which is often reported on a quarter-
end basis. Finally, many equity options expire at the end of quarters, 
making quarter-end prices particularly relevant for assessing option-
related risks.
    In determining the appropriate level of scenario severity, the 
Board adheres to the scenario design principles discussed in the 
earlier Section IX.F of this Supplementary Information. While doing so, 
the Board also strives to avoid introducing additional sources of 
procyclicality into the financial system. In the context of equity 
prices, these principles are applied in calibrating three key aspects 
of the guide: the trough value, the timing of the trough value, and the 
trajectory to trough. This approach helps ensure that the equity price 
guide aligns with the established stress testing literature while 
mitigating potential systemic risks for the financial system.
    The rest of this section is organized as follows. First, Table 11 
summarizes all of the equity prices guide components. This is followed 
by a detailed description of the guide's trough component, including 
the data- and scenario-based rationale for the calibration of the 
trough component and a discussion of the alternative trough option. 
Finally, additional guide parameters and the rationale for their 
calibration are discussed.

a. Trough Value Component of the Guide
    The proposed guide stipulates that the decline in equity prices 
from the jump-off value (i.e., the value of the equity price index at 
the end of the quarter immediately preceding the start of the scenario) 
will vary around 50 percent with an additional amount that offsets one 
half of the price growth over the prior year, up to 10 percent. These 
declines imply that equity prices would fall to a trough level that is 
between 40 and 60 percent below the jump-off value. More formally, this 
calibration implies that at the trough of the scenario path, equity 
prices fall by

Stock Market (Float Cap) Index (DWCF): End-of-quarter value via 
Bloomberg Finance L.P.; this index encompasses a wider universe of 
stocks than the S&P 500 Composite.
    \163\ In the academic literature, stock prices are well-known to 
be fast-moving or forward-looking variables that react to shocks 
quickly. One prominent example is the study by B. Bernanke, J. 
Boivin, & P. Eliasz, Measuring the Effects of Monetary Policy: a 
Factor-Augmented Vector Autoregressive (FAVAR) Approach, 120 Q. J.

moving variables that respond to shocks on impact).

---------------------------------------------------------------------------

Data- and Scenario-Based Rationale for the Trough Value
    In line with the scenario design principles for setting the 
scenario severity, discussed earlier in Section IX.F of this 
Supplementary Information, the rationale behind the choice of the 
neutral value of 50 percent comes from the data, as several recessions 
in the sample featured a decline of this magnitude. In particular, the 
equity price declines in the 1973 recession and the 2001 recession were 
46 percent, whereas the decline in the 2007-2009 financial crisis 
measured 48 percent (Table 12). The equity price decline in the 2007-
2009 financial crisis is most analogous to the scenario narrative, 
which starts with a substantial adverse shock to risk appetite and 
uncertainty and leads to a period of market disfunction followed by 
very high unemployment. Other financial stress episodes have seen 
maximum equity price declines of less than 50 percent, but in those 
instances the declines were not exacerbated by market dysfunction as 
considered in the scenario narrative.
    The adjustment portion of this guide responds to the possibility 
that economic or financial conditions at the beginning of the annual 
stress test cycle might warrant a decline in equity prices that is 
smaller or larger than 50 percent. This flexibility reduces the 
likelihood that the calibration of the trough would unduly amplify 
rising or falling valuation pressures in equity prices over the past 
year. When the stock market does well (or poorly) in the prior year, 
the guide stipulates that equity prices fall by more (respectively, 
less), with the exact amount determined by one half of the prior year's 
price change. The use of half instead of, for example, full price 
change results in troughs that are less likely to be unduly severe. 
This calibration of the guide is based on historical equity market 
valuations. However, when recent price moves are not consistent with 
fundamentals or longer-term trends, the Board could deviate from the 
proposed guide and use price growth over a longer horizon.
[GRAPHIC] [TIFF OMITTED] TP18NO25.049

    The choice of 10 percentage points as the upper bound for the 
absolute value of the year-to-year variation in this scenario variable, 
or equivalently the choice of effective bounds (between 40 and 60 
percent) on the trough decline, is rooted in the data and is similar to 
changes that have been used in past severely adverse scenarios. The 
upper end of the range would allow the Board to meaningfully increase 
scenario severity when equity market valuations are likely to be high 
or rising (as they were during the dot-com era) to ensure that firms 
are resilient to outsized losses if valuations return to more normal 
levels. The lower end of the range would allow the Board to reduce 
scenario severity if equity valuation pressures recently declined, as 
might be the case following a stock market correction or early in an 
economic recovery.\166\ Setting a floor for the decline in equity 
prices of 40 percent recognizes the fact that, not only do cyclical 
systemic risks build up at financial intermediaries during robust 
expansions, but a minimum level of risk exists even in an already 
stressed environment.
---------------------------------------------------------------------------

    \164\ The Board uses the DWCF for the scenarios because this 
index encompasses a wider universe of stocks compared with the S&P 
500 Composite. That said, the quantitative differences between the 
two measures are rather small. For instance, the implied declines in 
the dotcom episode would be 45.6 percent for both the Dow Jones time 
series and the S&P 500 Composite time series. Also, the overall 
correlation of the one-year growth rate computed for both time 
series on their common sample (1988Q1-2024Q4) is 0.99. Therefore, to 
cover a larger sample of historical episodes, the Board uses the S&P 
500 Composite time series to compute statistics in columns (1) and 
(2) and uses the DWCF to compute statistics in column (3).
    \165\ DWCF: End-of-quarter value via Bloomberg Finance L.P. and 
S&P 500 Composite via Bloomberg Finance L.P.
    \166\ Assessing equity market valuations requires some judgment 
as to the indicators that are used. Two commonly referenced 
indicators are the equity price to expected earnings ratio and the 
equity risk premium, which is the estimated expected return on 
equities minus the 10-year Treasury yield. These measures rely on 
projections of future earnings and other economic indicators that 
require additional judgments. Therefore, the Board has chosen to 
increase transparency and predictability by specifying this guide 
based on directly observable equity price changes and will typically 
use the guide rather than relying on judgmental assessments of other 
indicators of underlying valuation pressures.
---------------------------------------------------------------------------

    Figure 2 illustrates how the proposed guide performs relative to 
the 2014-2025 stress test cycles, comparing the guide-implied decline 
with those of past stress test scenarios and realized changes in equity 
prices. Overall, the troughs implied by the proposed guide (solid line) 
are similar to past scenario

[[Page 51899]]

troughs. However, deviations between the proposed guide and past 
scenarios have been distributed across lower or higher severity, 
implying that the proposed guide and the previous more-judgmental 
process can provide similar average severity across multiple years of 
stress tests. Indeed, the decline in equity prices in past stress test 
scenarios during 2014-2025 averages 52 percent, whereas the proposed 
guide's prescription of the declines for the same period averages 55 
percent. The slightly higher average decline is consistent with the 
principle of adequate severity discussed in Section IX.F of this 
Supplementary Information.

Alternative Trough Guide Option
---------------------------------------------------------------------------

    \167\ Bloomberg Finance L.P. (ticker: ``DWCF'') and Federal 
Reserve staff estimates.
---------------------------------------------------------------------------

    The Board considered an alternative in which the trough would be a 
50 percent decline from the jump-off value in equity prices 
unconditional on the previous year's price change and jump-off 
conditions. The 50 percent value is chosen based on the same reasons as 
the midpoint of the proposed guide. Although this alternative option is 
fully transparent and predictable, it has several weaknesses.
    On average, the proposed guide would prescribe troughs that would 
have been somewhat lower than the alternative if it had been 
operational over the past 12 years: 55 percent for the proposed guide 
on average vs 50 percent for the alternative. However, although a 50 
percent decline matches the judgmental average, it means that the test 
would be more severe each year than the decline observed during the 
2007-2009 financial crisis.
    Furthermore, as the alternative guide is not sensitive to the jump-
off conditions, the resulting troughs could be either excessive or 
insufficient in severity, thus exacerbating procyclicality in ways the 
proposed guide does not. This weakness would be particularly 
detrimental to the credibility of the stress test during long bull 
markets (as the United States has experienced during the stress testing 
era) or periods of protracted decline in equity prices as the stress 
test would be serially under- or over-stating the likely risks.
    The Board also considered a wider range in the proposed guide. An 
upper bound of 15 percentage points for the variable change relative to 
the midpoint of 50 percent would imply a much wider range of 35 to 65 
percent declines at the trough. A 65 percent decline has not been 
observed in the post-war US data, whereas a 35 percent equity price 
decline could be insufficiently severe to maintain credibility of the 
test at times of heightened uncertainty. An upper bound of 5 percentage 
points for the variable change from the midpoint would cover the 
relevant historical benchmarks but would provide a narrow range: 
between 45 and 55 percent decline at the trough. This choice would 
substantially limit the Board's ability to match the severity of the 
equity price decline with the recent performance in equity markets so 
might inadvertently add to procyclical forces in financial markets. A 
choice of 10 percentage points as the upper bound on the change 
relative to the 50 percent midpoint strikes a balance between an overly 
narrow and an overly wide adjustment window.
    Although the proposed and the alternative guides are both 
discussed, and the Board views the alternative guide as reasonable, the 
alternative guide's inability to respond to recent changes in equity 
valuations would be

[[Page 51900]]

a significant limitation compared with the proposed guide. The purpose 
of the alternative guide discussion is to invite comment on a 
reasonable alternative considered by the Board and to transparently lay 
out the Board's present arguments for choosing the proposed guide.
b. Additional Guide Parameters and Rationale Behind Them
Trough Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the trough and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The guide stipulates that 
the trough level in the scenario would be reached in quarter 3 or 
quarter 4, which is consistent with historical observations (Table 12). 
For instance, in the stress episode surrounding the 2007-2009 financial 
crisis, the trough for equity markets occurred three quarters after the 
bankruptcy of Lehman Brothers in 2008Q3.\168\ That timing also accords 
with the scenario narrative, in which a sudden and significant increase 
in uncertainty and rapid deterioration in risk appetite leads to a 
spike in financial market volatility and a sharp decline in U.S. 
financial assets during the first quarter of the scenario.
---------------------------------------------------------------------------

    \168\ Note that in the case of fast-moving variables (such as 
equity prices or the VIX), the Board times the onset of the stress 
period during the 2007-2009 financial crisis based on the Lehman 
Brothers bankruptcy rather than the NBER recession timing.
---------------------------------------------------------------------------

Trajectory to Trough Value
    To reach the trough value, the guide prescribes that between 60 and 
70 percent of the decline occurs in the first quarter of the scenario, 
10 to 20 percent of the decline occurs in the second quarter, with the 
remaining decline being realized about equally in the remaining 
quarter(s) to trough. This trajectory is consistent with the scenario 
narrative in which a severe recession is triggered by a large financial 
shock in the first quarter followed by a return to normal market 
functioning in subsequent quarters.
    These expected trajectory benchmarks reduce the variation in 
trajectories relative to previous scenarios: across past severely 
adverse scenarios, the median first quarter decline in equity prices 
was 68.3 percent of the total decline, so a range between 60 and 70 
percent is in line with the midpoint of past scenario choices. Also, 
across past severely adverse scenarios, the median second quarter 
decline in equity prices was 18.4 percent of the total decline, which 
is also within the range of 10 to 20 percent specified in this guide. 
Such a frontloaded decline is also consistent with the status of equity 
prices in the index of leading economic indicators and the empirical 
evidence from periods of equity market weakness.\169\ Across episodes 
of stock market distress, the average share of the decline realized in 
the two quarters preceding the trough amounts to 63 percent, with one 
episode measuring a much higher 88 percent in one quarter (in 1962) and 
most measuring 50 percent or more for these two quarters (for example, 
52 percent in the 2007-2009 financial crisis).\170\
---------------------------------------------------------------------------

    \169\ In the academic literature, stock prices are well-known to 
be fast-moving or forward-looking variables that react to shocks 
fast. See infra note 163.
    \170\ The episodes of stock market distress include the 
recessions of 1969, 1973, 2001, the 2007-2009 financial crisis as 
well as the stock market decline in 1962.
---------------------------------------------------------------------------

    In specifying a range for the timing of the trough and the 
proportion of declines in each quarter along the trajectory to the 
trough the Board maintains the option to create more or less severe 
scenarios if it wishes to avoid adding to existing procyclical factors 
or for another reason. An earlier trough with higher frontloading of 
the declines generally would be more severe. The Board could consider 
an earlier trough timing or higher frontloading when economic and 
financial market conditions are buoyant, such as when equity prices 
have increased by more than the maximum 10 percent adjustment to the 
trough level. A delayed trough timing and lower frontloading generally 
would decrease the scenario severity. The Board could consider delayed 
timing of the trough or smaller frontloading when equity prices at 
jump-off are depressed but have been increasing, or are projected to 
increase, and firms have de-risked and begun to recognize related 
losses.
VIX
    The stress test scenarios set out trajectories for several 
variables, including the VIX, that is, the Chicago Board Options 
Exchange's CBOE Volatility Index. The VIX is an index measuring implied 
volatility based on a portfolio of options of the Standard and Poor's 
500 (S&P 500).\171\ The VIX is calculated and distributed by the 
Chicago Board Options Exchange.\172\
---------------------------------------------------------------------------

    \171\ The S&P 500 is a stock market index tracking the stock 
performance of 500 leading companies listed on stock exchanges in 
the United States.

(ticker: ``VIX Index'').
---------------------------------------------------------------------------

    The VIX is often referred to as the ``fear index'' because it 
measures the market's expectation of future volatility. Furthermore, 
equity market volatility has been often used as an indicator of the 
price of risk, along with the spreads, which can depress economic 
activity when elevated.\173\
---------------------------------------------------------------------------

    \173\ The role of equity market volatility as an indicator of 
the price of risk (along with the spreads) is discussed in T. 
Adrian, N. Boyarchenko, & D. Giannone, Vulnerable Growth, 109 Am. 
Econ. Rev. 1263-89 (2019). Relatedly, the National Financial 
Conditions Index (NFCI) of the Federal Reserve Bank of Chicago 
constructs a risk subcomponent that is based on co-movement between 
volatility measures and spreads. See S. Brave & A. Butters, 
Diagnosing the Financial System: Financial Conditions and Financial 
Stress, 8 International Journal of Central Banking 191-239 (2012)
---------------------------------------------------------------------------

    In the supervisory stress test models that use the macroeconomic 
scenario, the VIX can act as an indicator of stress for a wide range of 
important assets and income streams even if those business lines are 
not specifically linked to the VIX index. By incorporating the VIX into 
scenarios, stress tests help ensure that firms are prepared for a wide 
range of market conditions, including periods of extreme volatility and 
uncertainty and any associated economic downturn.\174\ This helps 
maintain the overall stability and resilience of the financial system.
---------------------------------------------------------------------------

    \174\ See, e.g., N. Bloom, The Impact of Uncertainty Shocks, 77 
Econometrica 623-85 (2009); S. Baker, N. Bloom, & S. Davis, 
Measuring Economic Policy Uncertainty, 131 Q. J. of Econ. 1593-1636 
(2016).
---------------------------------------------------------------------------

    In the supervisory stress test scenarios, the VIX is converted to 
quarterly frequency using the maximum close-of-day value in any quarter 
and expressed in percent. The Board's use of this aggregation method in 
the scenarios, rather than average or quarter-end values as used for 
other variables, is a deliberate choice to have at least one scenario 
variable that reflects the unique nature of market volatility and its 
impact on financial institutions. This approach ensures firms are 
tested against the most extreme, potentially destabilizing market 
conditions, even if short-lived. Short-term and sharp increases in the 
VIX can reflect markets' initial response to changes in risk appetite 
or the economic outlook that then have longer-lasting adverse effects 
on the broader economy, such as reduced employment.\175\ Moreover, the 
use of the maximum close-of-day values captures the non-linear effects 
of volatility spikes on financial instruments, risk models, and 
liquidity,

[[Page 51901]]

while also testing firms' ability to handle rapid market movements, 
margin calls, and behavioral factors during peak stress.

---------------------------------------------------------------------------

    In determining the appropriate level of scenario severity, the 
Board adheres to scenario design principles discussed in Section IX.F 
of this Supplementary Information. While doing so, the Board also 
strives to avoid introducing additional sources of procyclicality into 
the financial system. In the context of the VIX, these principles are 
applied in calibrating three key aspects of the guide: the peak value, 
the timing of the peak value, and the trajectory to peak. This approach 
ensures that the VIX guide aligns with the established stress testing 
literature while mitigating potential systemic risks for the financial 
system.
    The rest of this section is organized as follows. First, Table 13 
provides an overview of the VIX guide components, which is followed by 
the guide description of the peak component. A data- and scenario-based 
rationale for the calibration of the peak component follows in the next 
subsection. Next is a discussion of an alternative peak option, 
comparing the implementation and caveats to the proposed guide option. 
Finally, additional guide parameters and the rationale for their 
calibration are discussed.
---------------------------------------------------------------------------

    \176\ Theoretically, there is no upper bound on the VIX; i.e., 
it is not constrained by 100 percent (or any other ceiling value). 
However, a value surpassing 100 percent would require extraordinary 
levels of daily market volatility and has never been observed in the 
historical sample, spanning 1990Q1-2025Q1.

a. Peak Value Component of the Proposed Guide
    The VIX will increase to a level between 65 percent and 75 percent 
or by at least 10 percentage points from the jump-off value, whichever 
results in a higher level.\176\
Data- and Scenario-Based Rationale for the Peak Value
    In line with the scenario design principles for setting the 
scenario severity, discussed in Section IX.F of this Supplementary 
Information, the VIX guide calibrates the minimum level to be between 
65 percent and 75 percent. This choice is consistent with the 
historical observations during periods of stress (Table 14). In 
particular, the proposed range for the peak value of the guide is 
calibrated based mainly on the range of VIX realizations across four 
recent recessions or episodes of financial stress. The minimum value of 
65 also reflects a judgment that the stress test always must be 
consistent with the goal of promoting financial stability, which means 
that markets and the public must continue to view the stress test as 
sufficiently severe to maintain confidence, especially during periods 
of high uncertainty and volatility.\177\ Thus, the lower end of the 
range for the guide is chosen to be modestly above the average VIX peak 
of 61 percent (first column). Moreover, setting a floor for the 
increase in the VIX of 65 percent recognizes the fact that, not only do 
cyclical systemic risks build up at financial intermediaries during 
robust expansions, but a minimum level of risk exists even in an 
already stressed environment. The higher end of the range is close to 
the maximum value across those periods, 83 percent, which was observed 
during the COVID-19 pandemic (third column).
---------------------------------------------------------------------------

    \177\ See Judge (2022), supra note 103.

---------------------------------------------------------------------------

[[Page 51902]]

[GRAPHIC] [TIFF OMITTED] TP18NO25.052

    The minimum increment of 10 percentage points would only be 
relevant if the jump-off occurred during a period of already-high 
volatility (for example, in the 2007-2009 financial crisis, when the 
peak was 81 percent, or in the COVID-19 pandemic, when it was 83 
percent). In such an instance, the guide allows for the possibility 
that conditions could worsen further, given the other aspects of the 
severely adverse scenario, such as the increase in unemployment and 
decline in house prices from the baseline. This assumption ensures that 
the VIX scenario peak is adequately severe. Limiting the increase to 10 
percentage points ensures, however, that the peak does not deviate too 
far from historically observed levels and become unduly contractionary.
---------------------------------------------------------------------------

    \178\ Source: Data for the VIX are from the Chicago Board 
Options Exchange via Bloomberg Finance L.P. (ticker: ``VIX Index'') 
and span the period 1990Q1-2025Q1.
---------------------------------------------------------------------------

    Figure 3 plots historical VIX data, past scenario peaks, and this 
guide (solid lines). On average across the past stress test scenarios 
(2014-2025), the VIX has been approximately 30 percent at the jump-off 
quarter, i.e., the data observation serving as a starting point for the 
scenario. The implied increase from the initial condition to the peak 
can be quite large--in such instances where the VIX is around 30 
percent at the jump-off quarter, the increase to the peak value would 
be between 35-45 percentage points. Such rapid increases in the VIX are 
consistent with what occurred during the four stress episodes 
considered in this calibration. On average across those episodes, which 
start in 1990Q1 when data for the VIX became available, the VIX 
increases by approximately 39 percentage points from the onset of a 
stress event, which is one quarter before the start of the NBER 
recession date, to its peak, a value within the range implied by the 
guide (see Table 14, first column).

[[Page 51903]]

[GRAPHIC] [TIFF OMITTED] TP18NO25.053

    Figure 3 illustrates the comparison of the guide-implied peak range 
of the VIX (delineated by the solid lines) against the peaks in past 
stress test scenarios (shown as dots), accompanied by the respective 
jump-off points from the data (dashed line). Two key results emerge. 
First, past peaks chosen by the Board in previous severely adverse 
scenarios are mostly within the bounds that would have been stipulated 
by the VIX guide. In the two instances where the Board would have been 
more constrained, one episode was higher than the upper bound and the 
other lower than the lower bound. Thus, the guide is likely to result, 
on average, in similar stress test severity as before this revision to 
the policy statement while having the benefit of each individual year's 
scenario being more transparent and predictable. Second, the 
flexibility in the proposed guide to have a minimum increase of 10 
percentage points provides adequate severity during stressful times, 
even beyond the upper end of the range for typical jump-off quarters. 
For instance, in 2020Q1, when the COVID-19 pandemic unfolded and the 
VIX jumped, reaching the historical maximum of the VIX, the prescribed 
peak would have been higher than 75 percent. Given the severity of the 
underlying conditions in 2020Q1, the peak would be determined by the 
jump-off point and the 10-percentage-point increment, resulting in a 
peak of 93 percent.

---------------------------------------------------------------------------

    In its formulation of the annual scenarios, the Board's 
considerations would include the overall level of cyclical systemic 
risk, the current level of the VIX as a contemporaneous indicator of 
uncertainty and financial stress, and the performance of equity prices 
within the past 12 months as a forward-looking indicator of economic 
and financing conditions to determine the appropriate increase in the 
VIX in the scenario. As discussed in Section IX.F of this Supplementary 
Information, the Board expects to calibrate the increment in the VIX 
based on its views of the status of cyclical systemic risk. 
Specifically, the Board would be more likely to set the VIX peak value 
at the higher end of the range if the Board expects that cyclical 
systemic risks are high (as it would be after a sustained long 
expansion), and alternatively would be more likely to set the peak 
value to the lower end of the range if cyclical systemic risks are low 
(as it would be in the earlier stages of a recovery), provided doing so 
remained consistent with the goal of ensuring that firms were properly 
capitalized to withstand severe economic and financial conditions. This 
may result in a scenario that is more intense than normal if the Board 
expects that cyclical systemic risks were to be increasing in a period 
of sustained robust expansion. Conversely, it would also allow the 
Board to specify a scenario that is less intense than normal in an 
environment where systemic risks appeared subdued, such as in the early 
stages of a recovery. This choice would consider that the scenario does 
not add unduly to remaining stress, thereby exacerbating the initial 
adverse shock. The lower end of the increase range could also be 
appropriate when underlying market uncertainty and financial stress 
start to recede and higher-than-usual credit losses stemming from 
previously elevated vulnerabilities were either already realized--or 
are in the process of being realized--and thus removed from firms' 
balance sheets.\180\
---------------------------------------------------------------------------

    \180\ Evidence of market uncertainty and financial stress 
receding could include strong stock market performance or positive 
economic news related to GDP, unemployment or nonfarm payroll. 
Evidence that credit losses are being realized could include 
elevated charge-offs on loans and leases or loan-loss provisions in 
excess of gross charge-offs.
---------------------------------------------------------------------------

Alternative Peak Guide Option
    The Board considered an alternative in which the VIX would increase 
to 75 percent or by at least 10 percentage points from the jump-off 
value, whichever results in a higher level. In this alternative peak 
option, the VIX would be set at a level of 75 percent in typical future 
scenarios. This prescriptive implementation would follow the principle 
of conservatism by always moving the VIX close to its historical 
maximum. It would also have the benefit of increasing the 
predictability of the guide. However, when the VIX at the jump-off 
value is elevated but has been declining or is

[[Page 51904]]

projected to decline and firm balance sheets are recovering, this 
alternative would remove the Board's discretion to choose a lower peak 
for the VIX. A lower but still constant value for the VIX guide in a 
typical scenario, for instance with a lower bound of 65 percent 
(corresponding to the average value across past scenarios) might not 
provide sufficient resilience in normal times, as the actual peaks of 
the VIX in the 2007-2009 financial crisis and during the COVID-19 
pandemic exceeded 80 percent. Although a lower anchor could be coupled 
with a higher minimum increment value--for example, 20 percentage 
points--such a large increment in already stressful times removes the 
Board's discretion to choose a less severe VIX peak. Although the 
proposed and alternative guides are discussed, and the Board views a 
more restrictive alternative guide as potentially reasonable, the Board 
believes the alternative guide is inferior to the proposed guide, given 
the variation in peak levels of the VIX the Board has found appropriate 
in past stress test scenarios. Nonetheless, the purpose of the 
alternative guide discussion is to invite comment on a reasonable 
alternative considered by the Board and to transparently lay out the 
Board's present arguments for choosing the proposed guide.
b. Additional Guide Parameters and Rationale Behind Them
Peak Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the peak and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The guide stipulates that 
the peak level in the scenario would be reached in quarter 2, which is 
consistent with past severely adverse scenarios and historical 
observations. The peak was reached in quarter 2 in both the 2007-2009 
financial crisis and in the COVID-19 pandemic (see Table 14).\181\ 
Averaging across all four financial stress episodes used to calibrate 
the guide yields a peak in quarter 3. As historical maximum values of 
the VIX were reached in the 2007-2009 financial crisis and during the 
COVID-19 pandemic, and the scenario narrative specifies that the event 
is triggered by a financial crisis similar to events in the fall of 
2008, the Board considers the peak timing in quarter 2 more appropriate 
for both the proposed and the alternative guide.
---------------------------------------------------------------------------

    \181\ The Board determined that the timing of the start of the 
stress period should sometimes differ from the start date of the 
recession determined by the NBER. For potentially fast-moving 
variables (such as the VIX), the Board times the onset of the stress 
period during the 2007-2009 financial crisis based on the Lehman 
Brothers bankruptcy on September 15, 2008. This event is widely 
considered to be the most significant of the events that roiled 
financial markets during the 2007-2009 financial crisis episode. As 
stress test data operate at quarterly frequency, the Board's timing 
of this event for determining the subsequent timing of the peak VIX 
is in 2008Q3. The focus on the Lehman Brothers bankruptcy as the 
triggering event is more consistent with the stress test scenario 
narrative in which a financial shock sets the stress test scenario 
dynamics in motion than the NBER recession date.
---------------------------------------------------------------------------

Trajectory to Peak Value
    To reach the peak value, the guide prescribes that the highest 
share, 60 to 80 percent, of the VIX increase occurs in the first 
quarter of the scenario. Such frontloading of the increase is broadly 
consistent with empirical evidence and with the behavior of the other 
fast-moving variables (such as equity prices) in the scenario. 
Additionally, the academic literature considers the VIX (and other 
measures of uncertainty) a contemporaneous stress indicator that can 
respond to shocks on impact and stresses the importance of 
contemporaneous feedback between uncertainty and financial 
conditions.\182\ For instance, 100 percent of the increase in the VIX 
occurred in the first quarter of the 1990Q3-1991Q1 recession. During 
the 2007-2009 financial crisis, nearly 40 percent of the increase in 
the VIX occurred in the first quarter.\183\ In specifying a target for 
the proportion of increase to be realized in the first quarter, the 
Board would follow the same approach that it would use to assess 
appropriate severity for the peak value. In particular, during economic 
booms, the Board might formulate a scenario with greater frontloading 
of the VIX increases, as the scenarios with greater frontloading would 
contribute to higher severity. In the case of an economy that is 
characterized by moderate or slowing economic growth, the Board would 
likely stipulate the middle of the range of the VIX increases. Whereas 
in economic downturns or at the beginning of a recovery, the Board 
would expect to formulate a scenario with less frontloading of the VIX 
increases.
---------------------------------------------------------------------------

    \182\ The importance of contemporaneous feedback between 
uncertainty and financial conditions is discussed, for example, in 
S. Gilchrist, J. Sim, & E. Zakrajsek, Uncertainty, Financial 
Frictions, and Investment Dynamics, NBER Working Paper (2014), and 
D. Caldara et al., The Macroeconomic Impact of Financial and 
Uncertainty Shocks, 88 European Econ. Rev. 1166 (2016) (``Caldara 
(2016)'').
    \183\ See Table 14.
---------------------------------------------------------------------------

5-Year Treasury Yield
    The stress test scenario sets out trajectories for several 
variables, including the 5-year Treasury yield, which is measured using 
the quarterly average of the yield on 5-year U.S. Treasury notes.\184\
---------------------------------------------------------------------------

    \184\ This series is constructed by Federal Reserve staff based 
on the Svensson smoothed term structure model. L. Svensson, 
Estimating Forward Interest Rates with the Extended Nelson-Siegel 
Method, 3 Sveriges Riksbank Q. Rev. 13 -26 (1995).
---------------------------------------------------------------------------

    Because banks generally engage in maturity transformation by 
borrowing short-term (i.e., deposits) to fund longer-term assets, 
fluctuations in interest rates can affect their financial health in 
various ways.\185\ The 5-year Treasury yield is an important benchmark 
rate for credit markets and is, thus, directly related to the 
profitability of banks' investments in loans and securities as well as 
their trading activities. For example, a decline in longer-term 
Treasury yields that exceeds the decline in short-term yields (known as 
a flattening of the yield curve) tends to compress firms' net interest 
margins and can therefore reduce their profitability. At the same time, 
the decline in such yields tends to increase the market value of firms' 
investments in long-term fixed-rate bonds, some which is reflected in 
various measures of capital at firms.\186\ Incorporating the 5-year 
Treasury yield into the supervisory stress test helps to ensure that 
firms are prepared for a wide range of market conditions, including 
periods with a sudden decline in a credit market benchmark rate. This 
helps maintain the overall stability and resilience of the financial 
system.
---------------------------------------------------------------------------

    \185\ See W. English, S. Van den Heuvel, & E. Zakrajsek, 
Interest Rate Risk and Bank Equity Valuations, 98 Journal of 
Monetary Economics 80-97 (2018).
    \186\ The change in the fair value of securities held for sale 
is reflected in common equity for all firms and in common equity 
tier 1 for firms subject to Category I and Category II standards, as 
well as firms that opt into that treatment. See 12 CFR part 252.
---------------------------------------------------------------------------

    The Board uses a quarterly average of the 5-year Treasury yield in 
the stress test scenarios. Quarterly averages smooth out excessive (and 
potentially irrelevant) volatility that is present at daily or even 
monthly frequencies. Using quarterly averages strikes a balance between 
being sensitive enough to capture market trends and stable enough to 
avoid overreaction to market noise. Relatedly, the 5-year yield 
reflects long-term expectations of overall economic conditions. 
Therefore, removing short-term volatility from this measure via 
quarterly averaging is likely to, more-often-than-not, result in a

[[Page 51905]]

better representation of macroeconomic conditions.
    In determining the appropriate level of scenario severity, the 
Board adheres to scenario design principles discussed in Section IX.F 
of this Supplementary Information. While doing so, the Board also 
strives to avoid introducing additional sources of procyclicality into 
the financial system. In the context of the 5-year yield, these 
principles are applied in calibrating three key aspects of the guide: 
the trough value, the timing of the trough value, and the trajectory to 
trough. This approach ensures that the 5-year yield guide aligns with 
the established stress testing literature while mitigating potential 
systemic risks for the financial system.
    The rest of this section is organized as follows. First, Table 15 
presents an overview of the 5-year Treasury yield guide components, 
followed by the guide description of the trough component. The next 
subsection provides the data- and scenario-based rationale for the 
calibration of the trough component. A discussion of an alternative 
trough option follows in the next subsection, comparing the 
implementation and caveats to the proposed guide option. Finally, 
additional guide parameters (trough value timing and trajectory to the 
trough) and the rationale for their calibration are discussed.
[GRAPHIC] [TIFF OMITTED] TP18NO25.054

a. Trough Value Component of the Proposed Guide
    Under the proposed guide, the 5-year Treasury yield decreases from 
its starting value by 1.5 to 3.5 percentage points. The Board expects 
to determine the size of the scenario's decline based on relevant 
banking, macroeconomic, or other conditions in the economy or financial 
markets.\187\ Additionally, the size of the decline will likely be 
informed by (a) the behavior of short-term interest rates in the 
macroeconomic model for stress testing that the Board has developed 
specifically to aid in communicating the stress test scenario to the 
public,\188\ (b) estimates of the likely term premiums in a period of 
economic weakness consistent with the scenario narrative, and (c) risks 
that are apparent in relevant indicators of economic and financial 
conditions.\189\ However, the guide restricts the 5-year Treasury yield 
from falling below a lower bound of 0.3 percent or a decline of 0.3 
percentage points from the jump-off level, whichever is lower.
---------------------------------------------------------------------------

    \187\ Depending on the level of short-term interest rates, in 
some scenarios, the short-term rate could reach its trough slower 
than the 5-year and 10-year yields. In those cases, the scenario 
would include the inversion of the yield curve in the first few 
scenario quarters. Such behavior is in line with past scenarios as 
well as behavior of interest rates preceding past stress episodes, 
like the 2001Q1-2001Q4 recession, the 2007-2009 financial crisis and 
the COVID-19 pandemic.
    \188\ See https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.
    \189\ In the Board's macroeconomic model for the stress test, 
the path of the 5-year Treasury yield is determined as the sum of 
the expected federal funds rate implied by the scenario and the 
paths of the term premiums.
---------------------------------------------------------------------------

Data- and Scenario-Based Rationale for the Proposed Trough Value
    In the recession approach chosen by the Board, risk-free long-term 
interest rates fall because reduced economic activity and inflation 
result in an easing of monetary policy. As noted above, declining 
interest rates can have both positive and negative implications for 
firms' capital levels, depending on the firm's business model and the 
specific composition of its assets and liabilities at the start of the 
stress test.
    In line with these guiding principles as well as those emphasized 
by the stress testing literature discussed in Section IX.F of this 
Supplementary Information, the Board considers the behavior of the 5-
year Treasury yield during four financial stress episodes since the 
mid-1980s, including the 2007-2009 financial crisis, to calibrate the 
guide (Table 16).\190\ The average decline in the 5-year Treasury yield

[[Page 51906]]

during those financial stress episodes has been around 2.7 percentage 
points, ranging from 2.1 to 3.5 percentage points.\191\ Notably, the 
percentage-point decline in the 5-year yield across these recessions is 
consistent even though the level of the yield at the start of the 
period has varied considerably.
---------------------------------------------------------------------------

    \190\ In contrast with the calibration of other scenario 
variable guides, the Board considers the behavior of the 5-year 
Treasury yield during four financial stress episodes only after the 
mid-1980s. These financial stress episodes include NBER recessions 
in 1990Q3-1991Q1, 2001Q1-2001Q4, 2008Q3-2009Q2 (Lehman Brothers 
bankruptcy as a forcing event), and 2019Q4-2020Q2. For the purposes 
of calibrating representative yield behavior during stress episodes, 
the Board chose to focus on the recessions since the mid-1980s, as 
the period after the mid-1980s is characterized by a major monetary 
policy regime shift and stabilization in the interest rate 
environment. The mid-1980s marked the end of the ``Great 
Inflation,'' an era that began in the mid-1960s and was 
characterized by persistently high inflation and accommodative 
monetary policy. In response, monetary policy underwent a major 
regime shift in the early 1980s. This regime shift began the era of 
``Great Moderation'' marked by low and stable inflation and reduced 
macroeconomic volatility. See, e.g., R. Clarida, J. Gali, & M. 
Gertler, Monetary Policy Rules and Macroeconomic Stability: Evidence 
and Some Theory, 115 Q. J. of Econ. 147-80 (2000); Federal Reserve 
History, Federal Reserve Bank of St. Louis, ``Great Inflation,'' 
https://www.federalreservehistory.org/essays/great-inflation; 
Federal Reserve History, Federal Reserve Bank of St. Louis, ``Great 
Moderation,'' https://www.federalreservehistory.org/essays/great-moderation.
    \191\ The average decline during all the NBER recessions 
starting from the 1969Q4-1970Q4 recession is 2.5 percentage points, 
which is close to the average since the mid-1980s, but the range of 
declines is wider.

    The evidence from the historical stress episodes along with the 
principle of conservatism and the goal of avoiding the addition of 
sources of procyclicality suggest that a decline of 1.5 to 3.5 
percentage points in the 5-year Treasury yield would be reasonable. The 
lower end of the range (i.e., 1.5 percentage points) is somewhat below 
the historical average decline in the yield during financial stress 
episodes and in previous severely adverse scenarios (Table 14), leaving 
room to adjust the decline--and thus severity of the scenario--relative 
to the historical average. The 5-year yield declined by 2.1 percentage 
points during the 1990Q3-1991Q1 recession.

notes, constructed by Federal Reserve staff based on the Svensson 
smoothed term structure model. See Svensson (1995), supra note 184.
---------------------------------------------------------------------------

    The higher end of the range for the decline (i.e., 3.5 percentage 
points) is driven by observations in the data as well as the guiding 
principles: first, the largest decline in the 5-year yield during NBER 
recessions since the mid-1980s has been 3.5 percentage points. This 
decline took place during the 2001Q1-2001Q4 recession. However, outside 
recessions, there are episodes displaying more sizable drops in the 5-
year yield over the horizon of 13 quarters (matching the scenario 
horizon), the declines ranging from 2.6 to 6.1 percentage points. In 
particular, the episode spanning 1984Q2-1987Q2 had a drop of 6.1 
percentage points, the episode spanning 1990Q3-1993Q3 had a drop of 3.5 
percentage points, and the episode spanning 1999Q4-2002Q4 had a drop of 
3.1 percentage points. These observations suggest that a decline of 3.5 
percentage points in the 5-year yield is coherent with past 
experiences. Second, allowing the 5-year yield to potentially fall more 
than what has been observed, on average, during past recessions speaks 
to the guiding principle that adequate severity might sometimes require 
a scenario that is somewhat beyond typical historical experiences.
    The guide also imposes a 0.3 percent lower bound for the value of 
the 5-year Treasury yield. The Board opted for this near zero, albeit 
positive, lower bound for a few reasons. First, the lower bound is 
intended to limit the extent that an annual scenario may unduly 
disincentivize bank lending when the economy is entering or recovering 
from a severe downturn. Second, this choice increases the 
predictability of the 5-year Treasury yield path in the scenario. 
Third, the lower bound is calibrated to be in line with the historical 
episodes. The 5-year Treasury yield declined to similar levels during 
the COVID-19 pandemic, reaching 0.3 percent in 2020Q3. Finally, the 
guide imposes a decline of 0.3 percentage points in the yield when the 
jump-off value of the 5-year yield is close to or below its historical 
minimums at the scenario jump-off. In particular, this element binds 
when the yield is below 0.6 percent at the jump-off. This element 
further increases transparency on the yield trough level in the 
scenarios in various potential interest rate environments outside 
historical experiences.
    To illustrate how the trough levels of scenarios consistent with 
this guide would compare to the past stress test scenarios, consider 
the history of the 5-year yield and its scenario values at the trough 
over the period in which the Board has been conducting annual stress 
tests, from 2014 to 2025 (Figure 4). The past stress test scenario 
troughs are depicted as dots, whereas the range that is spanned by the 
proposed guide is indicated by the solid lines, incorporating the lower 
bound. The dashed line depicts the quarterly average of the 5-year 
Treasury yield observed in the data. This period contains both low- and 
high-interest rate environments: The quarterly average of the 5-year 
Treasury yield over that period was 2.1 percent, ranging between 0.3 
and 4.5 percent at the jump-off quarter.

[[Page 51907]]

[GRAPHIC] [TIFF OMITTED] TP18NO25.056

    During the periods in which the 5-year yield was below 1.7 percent, 
such as most quarters between 2013 and 2016, and 2020 to 2021, the 
guide would prescribe the lower bound for the 5-year yield. In a 
higher-rate environment, however, a severe drop in the 5-year yield 
would not necessarily imply a yield close to zero, which the guide 
takes into an account. Between 2017Q1 and 2019Q2, the interest rate 
environment was such that the decline in the yield within the range of 
1.5 to 3.5 percentage points would have provided the Board with the 
discretion to choose trough levels in the range of 0.3 and 1.4 percent. 
After 2022Q1, the proposed guide would have constrained the Board at 
times to a choice of yield levels significantly greater than the 0.3 
percent lower bound.
---------------------------------------------------------------------------

    \193\ Quarterly average of the yield on 5-year U.S. Treasury 
notes, constructed by Federal Reserve staff based on the Svensson 
smoothed term structure model. See Svensson (1995), supra note 184.
---------------------------------------------------------------------------

    Figure 4 also illustrates that the troughs implied by the proposed 
guide are quantitatively close to, but not the same as those featured 
in the past stress test scenarios during the low-interest-rate 
environment from 2013 to 2022 (the dots are located closer to the 
binding lower bound in most years). In several of those years, the 
Board chose a level for the trough that was modestly above the level 
that would have been prescribed by the guide and in one case the Board 
chose a level below the guide. However, with interest rates having 
risen to moderate levels between 2023 and 2025, the guide would have 
required the Board to choose a higher trough in 2024 and 2025 than it 
did.
    The Board considers these deviations from past scenarios to be an 
acceptable consequence of adopting the guide, given its goal of 
increasing predictability and transparency in the stress test. On the 
one hand, a more flexible guide, which would encompass a higher share 
of the past scenario troughs both in the lower and higher interest rate 
environments, would call for a wider range in the variable component of 
the guide. While a wider range would increase scenario flexibility, it 
would come at the expense of predictability. The proposed range strikes 
a balance between providing an adequate amount of flexibility to allow 
for adjusting scenario severity based on economic and financial 
conditions and keeping scenarios predictable. On the other hand, 
keeping the range as is, one could also consider shifting the range up 
or down to better enclose the past scenario troughs. If the range was 
shifted down (e.g., 1.0 to 3.0 percent), the guide would better 
encompass the past scenario troughs during the low-interest-rate 
periods, but the opposite would be true for the post-COVID-19 periods. 
If the range was shifted up (e.g., 2.0 to 4.0 percent), the guide would 
better encompass the past scenario troughs between 2023 and 2025, but 
the lower bound would bind for a larger number of scenario troughs 
between 2013 and 2021. Thus, shifting the range would not meaningfully 
change how well the guide aligns with the past scenario troughs. 
Lastly, as the deviations from past scenarios would have been in both 
directions, the Board expects that the proposed guide will be broadly 
consistent with maintaining an average level of severity of stress 
tests going forward that is similar to what it has been under the 
Scenario Design Policy Statement.
    In setting the 5-year Treasury yield trough value, the Board could 
consider the overall level of cyclical systemic risk, and the current 
level of the 5-year Treasury yield as a benchmark measure of overall 
economic and financing conditions. As discussed earlier in Section IX.F 
of this Supplementary Information, the Board expects to calibrate the 
increment in the 5-year yield in consideration of observable cyclical 
systemic risk. The Board would also consider how declines in Treasury 
yields, which decrease net income but increase the market value of 
firms' long-term securities holdings, interact with the current 
vulnerabilities in the banking sector. In general, a decline in long-
term interest rates may have a positive or negative effect on the 
severity of the scenario for a given firm

[[Page 51908]]

depending on the firm's exposure to interest rate risk, which may vary 
from year to year depending on the firm's portfolio. In reaching its 
determination to set this guide in an annual scenario, the Board will 
consider how the choice would promote stress test credibility and the 
resilience of the financial system to even worse outcomes. If the Board 
observes that cyclical systemic risks were increasing in a period of 
sustained robust expansion, the Board might choose a scenario that is 
more severe than normal. The choice would also depend on firms' 
exposure to interest rate risk. Conversely, the Board could specify a 
scenario that is less intense than normal in an environment where 
systemic risks appeared subdued, such as in the early stages of a 
recovery, provided that doing so remained consistent with the goal of 
ensuring that firms were properly capitalized to withstand severe 
economic and financial conditions. A less severe scenario could also be 
appropriate when underlying market uncertainty and financial stress 
start to recede and higher-than-usual credit losses were either already 
realized--or are in the process of being realized--and thus removed 
from firms' balance sheets. The choice would consider that the scenario 
does not add unduly to remaining stress, thereby exacerbating the 
initial adverse shock, and it would be particularly appropriate if the 
Board judges that firms are already taking steps to reduce their 
risk.\194\
---------------------------------------------------------------------------

    \194\ Evidence of market uncertainty and financial stress 
receding could include strong stock market performance or positive 
economic news related to GDP, inflation, unemployment or nonfarm 
payroll. Evidence that credit losses are being realized could 
include elevated charge-offs on loans and leases or loan-loss 
provisions in excess of gross charge-offs.
---------------------------------------------------------------------------

Alternative Trough Guide Option
    As an alternative, the Board also considered a guide in which the 
5-year Treasury yield would decline by 2.5 percentage points regardless 
of the jump-off conditions, with the lower bound still applying. Under 
this alternative, the decline of 2.5 percentage points is chosen based 
on the same observations shown in Table 16. In particular, 2.5 
percentage points is close to the average decline in the 5-year 
Treasury yield observed during the financial stress episodes (2.7 
percentage points). The choice of a single value in the middle of the 
range proposed in the proposed version of this guide reflects the 
offsetting effects of interest rates on net interest margin and fair 
value of securities.
    The Board considered this alternative because of its goal of 
increasing transparency and predictability of the stress test, while 
maintaining sufficient severity. However, the Board recognizes that 
this alternative guide would not avoid adding sources of procyclicality 
as effectively as the proposed guide. In particular, it would reduce 
the Board's flexibility during periods of moderate or high interest 
rates to test the resilience of firms' net income to a sharper decline 
in interest rates. However, as noted above, declines in yields have 
offsetting effects on firms' regulatory capital in the stress test 
because they decrease net income but increase the market value of their 
long-term securities holdings. Thus, a more flexible guide could have 
more-balanced effects on the stress capital buffer calculated from the 
stress test results.
    While the alternative troughs fall within the range determined by 
the proposed guide, these trough levels can be significantly higher or 
lower than the values chosen by the Board in prior severely adverse 
scenarios. These deviations could impair the Board's ability to ensure 
that the stress test severity fully considers the risks that are 
apparent in relevant indicators of economic and financial conditions, 
particularly those related to the Treasury term premium, when 
determining the trough value. The Board views the alternative guide as 
reasonable. As compared to the proposed guide, the alternative guide 
would provide firms and the public with increased predictability 
regarding the trough value to be set for 5-year Treasury yields. 
However, this increased predictability under the alternative guide 
comes at the expense of the added flexibility inherent in the proposed 
guide to set the trough based on risks that are apparent in relevant 
indicators of economic and financial conditions and to avoid adding 
sources of procyclicality in the proposed guide. The purpose of the 
alternative guide discussion is to invite comment on a reasonable 
alternative considered by the Board and to transparently lay out the 
Board's present arguments for choosing the proposed guide.
b. Additional Guide Parameters and Rationale Behind Them
Trough Value Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the trough and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The proposed guide 
suggests that the 5-year Treasury yield would reach the trough between 
quarters 1 and 4 of the scenario. This timing is chosen such that the 
trough is consistent with the scenario narrative: the severely adverse 
scenario is triggered by a sizeable financial shock combined with a 
pronounced increase in unemployment and decrease in inflation. In 
response to these developments, both short- and long-term interest 
rates typically would fall sharply. The timing of the trough is also 
broadly consistent with the historical data (Table 16). Averaging 
across the four financial stress episodes, the trough is placed in the 
fifth quarter, but the trough occurred earlier during the two most 
recent recessions.\195\ The 5-year yield reached its trough in quarter 
3 during the 2007-2009 financial crisis and in quarter 4 during the 
COVID-19 pandemic. In the past stress test scenarios, the trough was 
also reached in quarter 3, on average. In setting this part of the 
guide in an annual scenario, the Board expects to consider the same 
indicators and other factors described above for the choice of the 
trough in the 5-year rate, so as best to promote stress test 
credibility and the resilience of the financial system to even worse 
outcomes.
---------------------------------------------------------------------------

    \195\ These four episodes include 1990Q3-1991Q1, 2001Q1-2001Q4, 
2008Q3-2009Q2 (Lehman Brothers bankruptcy as a forcing event), and 
2019Q4-2020Q2 recessions.
---------------------------------------------------------------------------

Trajectory to Trough Value
    The proposed guide stipulates that the largest share of the decline 
in the 5-year Treasury yield would be realized in quarter 1. A rapid, 
frontloaded decline of the 5-year yield to its trough would be 
consistent with the scenario narrative and the implied dynamics of the 
other variables, mainly the large increase in unemployment and 
resulting declines in inflation and output. In response to these 
developments, both short- and long-term interest rates would fall 
sharply, consistent with the Board's macroeconomic model for stress 
testing, and specifically the expectational component of the 5-year 
Treasury yield, which accounts for the future expected realizations of 
the macro variables that determine the policy rate rule.\196\
---------------------------------------------------------------------------

    \196\ Existing studies suggest that it is beneficial to 
frontload interest rate cuts in response to shocks. See, e.g., R. 
Caballero & A. Simsek, A Note on Temporary Supply Shocks with 
Aggregate Demand Inertia, 5 Am. Econ. Rev.: Insights 241-58 (2023); 
R. Caballero & A. Simsek, Monetary Policy and Asset Price 
Overshooting: a Rationale for the Wall/Main Street Disconnect, 79 J. 
of Fin. 1719-53 (2024).
---------------------------------------------------------------------------

    To determine the specific path of the 5-year Treasury yield for a 
given trough timing, the Board considered a simple formula that can map 
the trough value timing to a share of decline in quarter

[[Page 51909]]

1. To do so, the Board considered lower and upper bound of trough 
timing described in the previous section. If the trough timing is 
quarter 1 (e.g., lower bound of the range), then the formula should 
yield 100 percent of the decline occurring in the first quarter. For 
trough timing of quarter 4, the Board took example of COVID-19 
pandemic. During the COVID-19 pandemic, the 5-year yield reached its 
trough in quarter 4, and nearly 50 percent of the decline in the 5-year 
yield was realized during the first quarter. Using these reference 
points, the Board concluded that the following simple formula could 
determine the approximate share of the decline realized in quarter 1 
---------------------------------------------------------------------------
as:

100%-15% * (Trough value timing-1).

    This simple formula stipulates that when the scenario trough is 
realized in quarter 4, about 55 percent of the decline would be 
realized in quarter 1:

100%-15% * (4-1) = 55%

    This result is broadly in line--if not exactly in line--with the 
data from the COVID-19 pandemic. The guide also stipulates that, after 
the initial decline realized in quarter 1, the yield declines to its 
trough at smoothly decreasing percent reductions.
10-Year Treasury Yield
    The stress test scenarios set out trajectories for several 
variables, including the 10-year Treasury yield, which is measured 
using the quarterly average of the yield on 10-year U.S. Treasury 
notes.\197\ Because banks generally engage in maturity transformation 
by borrowing short-term (i.e., deposits) to fund longer-term assets, 
fluctuations in interest rates can affect their financial health in 
various ways. The 10-year Treasury yield is an important benchmark rate 
for credit markets and is, thus, directly related to the profitability 
of firms' investments in loans and securities as well as their trading 
activities. For example, a decline in longer-term Treasury yields that 
exceeds the decline in short-term yields (known as a flattening of the 
yield curve) tends to compress firms' net interest margins and can 
therefore reduce their profitability. At the same time, the decline in 
such yields tends to increase the value of firms' investments in long-
term fixed-rate bonds, some of which is reflected in various measures 
of capital at firms.\198\ Incorporating the 10-year Treasury yield into 
the supervisory stress test helps to ensure that firms are prepared for 
a wide range of market conditions, including periods with a sudden 
decline in a credit market benchmark rate. This helps maintain the 
overall stability and resilience of the financial system.
---------------------------------------------------------------------------

    \197\ This series is constructed by the Board based on the 
Svensson smoothed term structure model. See Svensson (1995), supra 
note 184.
    \198\ The change in the fair value of securities held for sale 
is reflected in common equity for all firms and in common equity 
tier 1 for firms subject to Category I and Category II standards, as 
well as firms that opt into that treatment. See 12 CFR part 252.
---------------------------------------------------------------------------

    The Board uses a quarterly average of the 10-year Treasury yield in 
the stress test scenarios. Quarterly averages smooth out excessive (and 
potentially irrelevant) volatility that is present at daily or even 
monthly frequencies. Using quarterly averages strikes a balance between 
being sensitive enough to capture market trends and stable enough to 
avoid overreaction to market noise. Relatedly, the 10-year yield 
reflects long-term expectations of overall economic conditions. 
Therefore, removing short-term volatility from this measure via 
quarterly averaging is likely to, more-often-than-not, result in a 
better representation of current macroeconomic conditions.
    In determining the appropriate level of scenario severity, the 
Board adheres to scenario design principles discussed in the earlier 
Section IX.F of this Supplementary Information. While doing so, the 
Board also strives to avoid introducing additional sources of 
procyclicality into the financial system. In the context of the 10-year 
yield, these principles are applied in calibrating three key aspects of 
the guide: the trough value, the timing of the trough value, and the 
trajectory to trough. This approach helps ensure that the 10-year yield 
guide aligns with the established stress testing literature while 
mitigating potential systemic risks for the financial system.
    The rest of this section is organized as follows. First, Table 17 
presents an overview of the 10-year Treasury yield guide components, 
followed by the guide description of the trough component. The next 
subsection provides the data- and scenario-based rationale for the 
calibration of the trough component. A discussion of an alternative 
trough option follows in the next subsection, comparing the 
implementation and caveats to the proposed guide option. Finally, 
additional guide parameters (trough value timing and trajectory to the 
peak) and the rationale for their calibration are discussed.

a. Trough Value Component of the Proposed Guide
    The 10-year Treasury yield decreases from its starting value by 
between 1.0 to 3.0 percentage points. The Board will determine the size 
of an annual scenario's decline based on a number of factors, including 
relevant banking, macroeconomic, or other conditions in the economy or 
financial markets.\199\ Additionally, the size of the decline will be 
informed by (a) the behavior of short-term interest rates in the 
macroeconomic model for stress testing that the Board has developed 
specifically to aid in communicating the stress test scenario to the 
public,\200\ (b) estimates of the likely term premiums in period of 
economic weakness consistent with the scenario narrative, and (c) risks 
that are apparent in relevant indicators of economic and financial 
conditions.\201\ However, the guide restricts the 10-year Treasury 
yield from falling below a lower bound of 0.5 percent or a decline of 
0.3 percentage points from the jump-off level, whichever is lower.
---------------------------------------------------------------------------

    \199\ Depending on the level of short-term interest rates, in 
some scenarios, the short-term rate could reach its trough slower 
than the 5-year and 10-year yields. In those cases, the scenario 
would include the inversion of the yield curve in the first few 
scenario quarters. Such behavior is in line with past scenarios as 
well as behavior of interest rates in past stress episodes, like the 
2001Q1-2001Q4 recession, the 2007-2009 financial crisis and the 
COVID-19 pandemic.
    \200\ See https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.
    \201\ In the macroeconomic model for stress testing, the path of 
the 10-year Treasury yield is determined as the sum of the expected 
federal funds rate implied by the scenario and the paths of the term 
premiums.
---------------------------------------------------------------------------

Data- and Scenario-Based Rationale for the Proposed Trough Value
    In the recession approach chosen by the Board, risk-free long-term 
interest rates fall because reduced economic activity and inflation 
result in an easing of monetary policy. As noted above, declining 
interest rates can have both positive and negative implications for 
firms' capital levels, depending on the firm's business model and the 
specific composition of its assets and liabilities at the start of the 
stress test.
    In line with these guiding principles as well as those emphasized 
by the stress testing literature discussed in Section IX.F of this 
Supplementary Information, the Board considers the behavior of the 10-
year Treasury yield during four financial stress episodes since the 
mid-1980s, including the 2007-2009 financial crisis, to calibrate the 
guide (Table 18).\202\ The average decline in the 10-year Treasury 
yield during those financial stress episodes has been around 1.9 
percentage points, ranging from 1.3 to 2.4 percentage points.\203\ 
Notably, the percentage-point decline in the 10-year yield across these 
recessions is similar even though the level of the yield at the start 
of the period has varied considerably.
---------------------------------------------------------------------------

    \202\ In contrast with the calibration of other scenario 
variable guides, the Board considers the behavior of the 10-year 
Treasury yield during four financial stress episodes only after the 
mid-1980s. These financial stress episodes include NBER recessions 
in 1990Q3-1991Q1, 2001Q1-2001Q4, 2008Q3-2009Q2 (Lehman Brothers 
bankruptcy as a forcing event), and 2019Q4-2020Q2. For the purposes 
of calibrating representative yield behavior during stress episodes, 
the Board chose to focus on the recessions since the mid-1980s, as 
the period after the mid-1980s is characterized by a major monetary 
policy regime shift and stabilization in the interest rate 
environment. The mid-1980s marked the end of the ``Great 
Inflation,'' an era that began in the mid-1960s and was 
characterized by persistently high inflation and accommodative 
monetary policy. In response, monetary policy underwent a major 
regime shift in the early 1980s. This regime shift began the era of 
``Great Moderation'' marked by low and stable inflation and reduced 
macroeconomic volatility. See supra note 190.
    \203\ The average decline during all the NBER recessions 
starting from the 1973Q4-1975Q1 recession--the first NBER recession 
for which the 10-year Treasury yield data is available--is also 1.9 
percentage points, but the range of declines is wider.
[GRAPHIC] [TIFF OMITTED] TP18NO25.058

    The evidence from the historical stress episodes along with the 
principle of conservatism and the goal of avoiding the addition of 
sources of procyclicality suggest that a decline of 1.0 to 3.0 
percentage points in the 10-year Treasury yield would be reasonable. 
The lower end of the range (i.e., 1.0 percentage points) is somewhat 
below the historical average decline in the yield during financial 
stress episodes and in previous severely adverse scenarios (Table 18), 
leaving room to adjust the decline--and thus severity of the scenario--
relative to the historical average. The 10-year yield declined by 1.3 
percentage points during the 1990Q3-1991Q1 recession.

Treasury notes, constructed by Federal Reserve staff based on the

note 184.
---------------------------------------------------------------------------

    The higher end of the range for the decline (i.e., 3.0 percentage 
points) is driven by observations in the data as well as the guiding 
principles: first, the largest decline in the 10-year yield during NBER 
recessions since the mid-

[[Page 51911]]

1980s has been 2.4 percentage points. This decline took place during 
both the 2001Q1-2001Q4 recession and the COVID-19 pandemic. However, 
outside recessions, there are episodes displaying more sizeable drops 
in the 10-year yield over the horizon of 13 quarters (matching the 
scenario horizon), the declines ranging from 2.2 to 5.8 percentage 
points. In particular, the episode spanning 1984Q2-1987Q2 had a drop of 
5.8 percentage points, the episode spanning 1990Q3-1993Q3 had a drop of 
3.0 percentage points, the episode spanning 1999Q4-2002Q4 had a drop of 
2.2 percentage points, and the episode spanning 2018Q4-2021Q4 had a 
drop of 2.4 percentage points. These observations suggest that a 
decline of 3.0 percentage points in the 10-year yield is coherent with 
past experiences. Second, allowing the 10-year yield to potentially 
fall more than what has been observed during past recessions, on 
average, speaks to the guiding principle that adequate severity should 
be somewhat beyond historical experiences.
    The guide also imposes a 0.5 percent lower bound for the value of 
the 10-year Treasury yield. The Board opted for this near zero, albeit 
positive, lower bound for a few reasons. First, the lower bound is 
intended to limit the extent that an annual scenario may unduly 
disincentivize bank lending when the economy is entering or recovering 
from a severe downturn. Second, this choice increases the 
predictability of the 10-year Treasury yield path in the scenario. 
Third, the lower bound is in line with the historical episodes. The 10-
year Treasury yield declined to similar levels during the COVID-19 
pandemic, reaching 0.6 percent in 2020Q3, but it has never fallen below 
that level. Finally, the guide imposes a decline of 0.3 percentage 
points in the yield when the jump-off value of the 10-year yield is 
close to or below its historical minimums at the scenario jump-off. In 
particular, this element binds when the yield is below 0.8 percent at 
the jump-off. This element further increases transparency on the yield 
trough level in the scenarios in various potential interest rate 
environments outside historical experiences.
    To illustrate how the trough levels of scenarios consistent with 
this guide would compare to the past stress test scenarios, consider 
the history of the 10-year yield and its scenario values at the trough 
over the period in which the Board has been conducting annual stress 
tests, from 2014 to 2025 (Figure 5). The past stress test scenario 
troughs are depicted as dots, whereas the range that is spanned by the 
proposed guide is indicated by the solid lines, which incorporate the 
lower bound. The dashed line depicts the quarterly average of the 10-
year Treasury yield observed in the data. This period contains both 
low- and high-interest rate environments, and the quarterly average of 
the 10-year Treasury yield (depicted as a dashed line) has been 2.5 
percent, with a range between 0.6 and 4.5 percent at the jump-off 
quarter.

    For periods when the 10-year yield is below 1.5 percent, such as 
the period surrounding the COVID-19 pandemic, the guide would prescribe 
the lower bound for the 10-year yield. In other periods between 2013-
2025, the 10-year yield has been high enough such that the lower bound 
of the guide is not strictly binding after applying the minimum amount 
of decline in the guide. In a higher-rate environment, a severe drop in 
the 10-year yield would not necessarily imply a yield close to zero. 
Figure 5 illustrates that the range of troughs consistent with the 
proposed guide usually includes the values

[[Page 51912]]

featured in the past stress test scenarios during the low-interest-rate 
environment from 2013 to 2022 (the dots are located within the guide-
prescribed range, or close to the binding lower bound in most years). 
In three of those years, the Board chose a level for the trough that 
was above the maximum level that would have been allowed by the guide 
and in two cases the Board chose a level modestly below the minimum 
level consistent with guide. With interest rates having risen to 
moderate levels between 2023 and 2025, the guide would have required 
the Board to choose a slightly higher trough in 2023 and 2025 and a 
notably higher trough in 2024 than the Board chose in those scenarios.

---------------------------------------------------------------------------

    The Board considers these deviations from past scenarios to be an 
acceptable consequence of adopting the guide, given its goal of 
increasing predictability and transparency in the stress test. As the 
deviations from past scenarios would have been in both directions, the 
Board expects that the proposed guide will be broadly consistent with 
maintaining an average level of severity of stress tests going forward 
that is similar to what it has been under the previous scenario design 
framework.
    In setting the 10-year Treasury yield trough value, the Board could 
consider the overall level of cyclical systemic risk, and the current 
level of the 10-year Treasury yield as a benchmark measure of overall 
economic and financing conditions. As discussed in earlier Section IX.F 
of this Supplementary Information, the Board expects to calibrate the 
increment in the 10-year yield in consideration of observable cyclical 
systemic risk. The Board would also consider how declines in Treasury 
yields, which decrease net income but increase the market value of 
firms' long-term securities holdings, interact with the current 
vulnerabilities in the banking sector. In general, a decline in long-
term interest rates may have a positive or negative effect on the 
severity of the scenario for a given firm depending on the firm's 
exposure to interest rate risk, which may vary from year to year 
depending on the firm's portfolio. In reaching its determination to set 
this guide in an annual scenario, the Board will consider how the 
choice would promote stress test credibility and the resilience of the 
financial system to even worse outcomes.
    If the Board observes that cyclical systemic risks were increasing 
in a period of sustained robust expansion, the Board might choose a 
scenario that is more intense than normal. The choice would also depend 
on firms' exposure to interest rate risk. Conversely, the Board could 
specify a scenario that is less intense than normal in an environment 
where systemic risks appeared subdued, such as in the early stages of a 
recovery, provided that doing so remained consistent with the goal of 
ensuring that firms were properly capitalized to withstand severe 
economic and financial conditions. A less severe scenario could also be 
appropriate when underlying market uncertainty and financial stress 
start to recede and higher-than-usual credit losses were either already 
realized--or are in the process of being realized--and thus removed 
from firms' balance sheets. The choice would consider that the scenario 
does not add unduly to remaining stress, thereby exacerbating the 
initial adverse shock, and it would be particularly appropriate if the 
Board judges that firms are already taking steps to reduce their risk--
for instance, by potentially restricting lending to otherwise qualified 
borrowers.\206\
---------------------------------------------------------------------------

    \206\ Evidence of market uncertainty and financial stress 
receding could include strong stock market performance or positive 
economic news related to GDP, inflation, unemployment, or nonfarm 
payroll. Evidence that credit losses are being realized could 
include elevated charge-offs on loans and leases or loan-loss 
provisions in excess of gross charge-offs.
---------------------------------------------------------------------------

Alternative Trough Guide Option
    As an alternative, the Board considered a guide in which the 10-
year Treasury yield would decline by 2.0 percentage points regardless 
of the jump-off conditions. The lower bound would still bind. The 
decline of 2.0 percentage points is chosen based on the same 
observations shown in Table 18. In particular, 2.0 percentage points is 
close to the average decline in the 10-year Treasury yield observed 
during the financial stress episodes (1.9 percentage points) and the 
average decline in previous severely adverse scenarios (1.7 percentage 
points). The choice of a single value in the middle of the range 
proposed in the more flexible version of this guide balances the 
offsetting effects of interest rates on net interest margin and fair 
value of securities.
    The Board considered this alternative because of its goal of 
increasing transparency and predictability of the stress test, while 
maintaining sufficient severity. The Board recognizes that this 
alternative guide would not avoid adding sources of procyclicality as 
effectively as the proposed guide. In particular, it would reduce the 
Board's flexibility during periods of moderate or high interest rates 
to test the resilience of firms' net income to a sharper decline in 
interest rates. However, as noted above, declines in yields have 
offsetting effects on firms' regulatory capital in the stress test 
because they decrease net income but increase the market value of their 
long-term securities holdings. Thus, a more flexible guide would allow 
the Board to balance its assessment of these two vulnerabilities in the 
stress test scenario.
    While the alternative troughs fall within the range determined by 
the proposed guide, these trough levels can be significantly higher or 
lower than the values chosen by the Board in prior severely adverse 
scenarios. These deviations could impair the ability of the Board to 
ensure the stress test severity that fully considers the risks that are 
apparent in relevant indicators of economic and financial conditions, 
particularly those related to inflation and inflation expectations, 
when determining the trough value. The Board views the alternative 
guide as reasonable. Compared to the proposed guide, the alternative 
guide would provide firms and the public with increased predictability 
regarding the trough value to be set for 10-year Treasury yields. 
However, this increased predictability under the alternative guide 
comes at the expense of the added flexibility inherent in the proposed 
guide to set the trough based on risks that are apparent in relevant 
indicators of economic and financial conditions and to avoid adding 
sources of procyclicality in the proposed guide. The purpose of the 
alternative guide discussion is to invite comment on a reasonable 
alternative considered by the Board and to transparently lay out the 
Board's present arguments for choosing the proposed guide.
b. Additional Guide Parameters and Rationale Behind Them
Trough Value Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the trough and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The proposed guide 
suggests that the 10-year Treasury yield would reach the trough in 
quarters 1 to 4 of the scenario. This timing is chosen such that the 
trough is consistent with the scenario narrative: the severely adverse 
scenario is triggered by a sizeable financial shock combined with a 
pronounced increase in unemployment and decrease in inflation. In 
response to these developments, both short- and long-term interest 
rates typically would fall sharply. The timing of the trough is also 
broadly consistent with the historical

[[Page 51913]]

data (Table 18). Averaging across the four financial stress episodes, 
the trough is placed in the sixth quarter, but the trough occurred 
earlier during the two most recent recessions.\207\ The 10-year yield 
reached its trough in quarter 3 during the 2007-2009 financial crisis 
and in quarter 4 during the COVID-19 pandemic. In the past stress test 
scenarios, the trough was reached in quarter 1, on average. In setting 
this part of the guide in an annual scenario, the Board will consider 
the same indicators and other factors described above for the choice of 
the trough in the 10-year rate, so as best to promote stress test 
credibility and the resilience of the financial system to even worse 
outcomes.
---------------------------------------------------------------------------

    \207\ These four episodes include 1990Q3-1991Q1, 2001Q1-2001Q4, 
2008Q3-2009Q2 (Lehman Brothers bankruptcy as a forcing event), and 
2019Q4-2020Q2 recessions.
---------------------------------------------------------------------------

Trajectory to Trough Value
    The proposed guide stipulates that the largest share of the decline 
in the 10-year Treasury yield would be realized in quarter 1. A rapid, 
frontloaded decline of the 10-year yield to its trough would be 
consistent with the scenario narrative and the implied dynamics of the 
other variables, mainly a large rise in unemployment and resulting 
declines in inflation and output. In response to these developments, 
both short- and long-term interest rates would fall sharply, consistent 
with the Board's macroeconomic model for stress testing, because the 
expectational component of the 10-year Treasury yield accounts for the 
future expected realizations of the macro variables that determine the 
policy rate rule.\208\
---------------------------------------------------------------------------

    \208\ See supra note 196.
---------------------------------------------------------------------------

    To determine the specific path of the 10-year Treasury yield for a 
given trough timing, the Board considered a simple formula that can map 
the trough value timing to a share of decline in quarter 1. To do so, 
the Board considered lower and upper bound of trough timing described 
in the previous section. If the trough timing is quarter 1 (e.g., lower 
bound of the range), then the formula should yield 100 percent of the 
decline occurring in the first quarter. For trough timing of quarter 4, 
the Board took example of COVID-19 pandemic. During the COVID-19 
pandemic, the 10-year yield reached its trough in quarter 4, and 52 
percent of the decline in the 10-year yield was realized during the 
first quarter. Using these reference points, the Board concluded that 
the following simple formula could set the approximate share of the 
decline realized in quarter 1 as:

100%-15% * (Trough value timing-1).

    This simple formula stipulates that when the scenario trough is 
realized in Quarter 4, about 55 percent of the decline would be 
realized in Quarter 1:

100%-15% * (4-1) = 55%.

    This is broadly in line--if not exactly in line--with the data from 
the COVID-19 pandemic. The guide also stipulates that, after the 
initial decline realized in quarter 1, the yield declines to its trough 
at smoothly decreasing percent reductions.
BBB Yield
    The stress test scenarios set out the trajectory of the BBB 
corporate spread, measured by the quarterly average of ICE BofA U.S. 
Corporate 7-10 Year Yield-to-Maturity Index relative to the 10-year 
Treasury yield.\209\ The BBB corporate spread represents the 
performance of corporate debt rated as investment grade by a major 
ratings agency.
---------------------------------------------------------------------------

    \209\ The source for the BBB corporate spread series is ICE 
BofAML U.S. Corporate 7-10 Year Yield-to-Maturity Index, ICE Data 
Indices, LLC, (C4A4 series). The 10-year yield is computed as the 
quarterly average of the yield on 10-year U.S. Treasury notes, 
constructed by Federal Reserve staff based on the Svensson smoothed 
term structure model. See Svensson (1995), supra note 184.
---------------------------------------------------------------------------

    Although firms subject to the supervisory stress test do not hold 
substantial volumes of BBB corporate bonds on their balance sheets, 
they make business loans to large- and middle-market firms and hold 
other types of business debt on their balance sheets, e.g., commercial 
and industrial (C&I) loans and collateralized loan obligations (CLOs). 
Corporate bond spreads and CLO spreads tend to move together in times 
of financial stress and high uncertainty. C&I loans to large- and 
middle-market firms, some of whom are also issuers of corporate bonds, 
account for 65 percent of total C&I loans. Because of these 
similarities with bond-issuing firms, changes in business conditions 
that underlie changes in spreads on BBB corporate bonds would affect 
these borrowers as well (and hence the balance sheets of the stress 
tested firms). In fact, empirical research finds that bank borrowers 
are more sensitive to macroeconomic and financial shocks than publicly-
traded borrowers due to their relatively more-restricted access to 
funding resources. Hence, in the context of the severely adverse 
scenario, the Board views BBB corporate bond spreads as a measure 
representing conditions in the business sector more generally.
    Instead of a higher frequency, such as daily, for which the 
underlying data is available, the Board uses a quarterly average of the 
BBB spreads in the stress test scenario for several reasons. First, BBB 
bonds face liquidity issues and their prices can be quite volatile at 
higher frequencies for reasons unrelated to underlying business 
conditions.\210\ Using quarterly averages strikes a balance between 
being sensitive enough to capture market trends and stable enough to 
avoid overreaction to high-frequency volatility. Relatedly, as noted 
above, in the context of stress testing, the BBB spreads provide a good 
representation of business borrowing and underlying economic 
confidence. Therefore, removing short-term noise from this measure via 
quarterly averaging results in a more reasonable representation of 
underlying business borrowing conditions.
---------------------------------------------------------------------------

    \210\ There is empirical support for excessive volatility in 
corporate bonds and find that it has little relation to firm 
fundamentals. J. Bao, & J. Pan, Bond Illiquidity and Excess 
Volatility, 26 Review of Financial Studies 3068-3103 (2013). In a 
working version of the paper, the authors stress that such excessive 
volatility is pervasive at higher frequencies, being the strongest 
at daily and weekly horizons and staying significant at monthly 
horizons. J. Bao & J. Pan, Excess Volatility of Corporate Bonds 
(2008), https://haas.berkeley.edu/wp-content/uploads/bond_vol.pdf.
---------------------------------------------------------------------------

    In determining the appropriate level of scenario severity, the 
Board adheres to scenario design principles discussed in the earlier 
Section IX.F of this Supplementary Information. While doing so, the 
Board also strives to avoid introducing additional sources of 
procyclicality into the financial system. In the context of the BBB 
spreads, these principles are applied in calibrating three key aspects 
of the guide: the peak value, the timing of the peak value, and the 
trajectory to peak. This approach helps ensure that the BBB spread 
guide aligns with the established stress testing literature while 
mitigating potential systemic risks for the financial system.
    The rest of this section is organized as follows. First, an 
overview of the BBB spread guide components is given in Table 19, which 
is followed by the description of the component of the guide that 
determines the peak of the spread. The next subsection provides the 
data- and scenario-based rationale for the calibration of the peak 
component. Next is a discussion of an alternative calibration for the 
peak component, comparing the implementation and caveats to the 
proposed guide option. Finally, additional guide parameters (peak value 
timing and trajectory to the peak) and the rationale for their 
calibration are discussed.

[[Page 51914]]

a. Peak Value Component of the Guide
    The BBB corporate bond yield is expected to move such that its 
spread relative to the 10-year Treasury yield would either increase 
from its initial level by 100 basis points or to a level ranging 
between 500 and 600 basis points, whichever results in a higher level.
Data- and Scenario-Based Rationale for the Peak Value
    In line with the guiding principles emphasized by the stress 
testing literature and discussed in Section IX.F of this Supplementary 
Information, the Board references the behavior of the BBB spreads 
during financial stress episodes, including the 2007-2009 financial 
crisis, to calibrate the guide for BBB spreads in the supervisory 
stress test scenarios. The higher end of the range for the peak level 
(i.e., 600 basis points) corresponds to the quarterly-average peak 
value observed during the 2007-2009 financial crisis (Table 19). 
Additionally, weekly averages of the BBB spread peaked at 688 basis 
points over the same period.\211\ The lower end of the range for the 
peak level (500 basis points) is motivated by the data as well. A level 
of 500 basis points also constitutes a severe BBB spread value from a 
statistical point of view.\212\ At daily frequency, the BBB spread 
reached values of around 500 basis points several times during the 
2007-2009 financial crisis and during the COVID-19 pandemic the BBB 
spread reached about 450 basis points.\213\
---------------------------------------------------------------------------

    \211\ Weekly average calculated using ICE BofA U.S. Corporate 7-
10 Year Yield-to-Maturity Index (ICE Data Indices, LLC) and the 
yield on 10-year U.S. Treasury notes, constructed by Federal Reserve 
staff based on the Svensson smoothed term structure model. See 
Svensson (1995), supra note.
    \212\ For instance, in the weekly data from December 1988 
through February 2025, 500 basis points and 600 basis points 
represent the top (i.e., the riskiest) percentiles of the BBB spread 
historical distribution: 98.5 and the 99.3, respectively.
    \213\ The daily frequency BBB spread peak during the COVID-19 
pandemic measured about 450 basis points, before declining after 
unprecedented government support programs were announced in March of 
2020. Stress tests are designed to assess firms in the absence of 
such government support. During the 2007-2009 financial crisis, the 
weeks in which spreads exceeded 500 basis points preceded the weeks 
with even higher BBB spread values.
---------------------------------------------------------------------------

    These examples illustrate that the value of 500 basis points 
represents a severe point in the historical distribution of the BBB 
spread observed during crisis events, which could be followed by 
further worsening of conditions. Even if peaks of 500 to 600 basis 
points have been rather short-lived, they could potentially trigger 
events that would cause inadequately capitalized firms to fire-sale 
their assets--a risk the Board seeks to reduce through the use of 
stress testing. Moreover, setting a floor for the BBB spread at 500 
basis points recognizes that, not only are cyclical systemic risks 
likely to build up at financial intermediaries during robust 
expansions, but that these risks are also easily obscured by a buoyant 
environment.
    To ensure sufficient severity in the event that the BBB spread at 
the start of a stress test cycle is around or higher than the peak 
levels attained in the history (e.g., above 500 basis points), the 
Board contemplates a minimum increment of 100 basis points, in line 
with the principle that adequate severity requires a guide to be able 
to go somewhat beyond historical experiences when initial conditions 
warrant.\214\ The minimum increment of 100 basis points ensures 
adequate scenario severity, maintaining the credibility of the stress 
test while at the same time constraining the peak from becoming unduly 
contractionary and deviating too far from historically observed 
levels.\215\ Applying a larger value of a minimum increment (e.g., 200 
basis points) could result in a peak level that is unjustifiably 
distant from historical peaks and might not allow the Board to reflect 
near-term changes, such as emerging signs of financial stabilization, 
resulting in inappropriately high scenario severity at a time when the 
economy and financial markets are already stressed.
---------------------------------------------------------------------------

    \214\ See Schuermann (2014), supra note 99.
    \215\ If a future financial distress event causes the BBB spread 
to rise beyond the current peak of about 600 basis points, the Board 
may consider an update of the peak range to reflect that new 
empirical evidence in subsequent future tests.

    To illustrate how the Board would use this guide to formulate the 
scenarios, and how the implied peak levels of the guides compare to the 
past stress test scenarios, consider the jump-off values in 2014-2025 
cycles, the period during which the Board has been conducting stress 
tests (Figure 6). The past stress test scenario peaks are depicted as 
dots in the figure, whereas the proposed guide is indicated as a range 
by the solid lines. This period contains both stressful times (the 
COVID-19 pandemic) as well as the slow recovery after 2009 and some 
periods of very low unemployment and robust growth. It is therefore 
quite representative in capturing a variety of jump-off values. In this 
time frame, the quarterly average of the BBB spread (depicted as a 
dashed line) has been between about 100 and 265 basis points at the 
jump-off quarter, while the average of those quarterly jump-off values 
was about 170 basis points. Going to 500 or 600 basis points from such 
jump-off values represented a substantial increase in the spread, 
possibly more than 400 basis points. This is a plausible increase when 
markets become strained or bad economic news pervades. For instance, 
during the 2007-2009 financial crisis, the difference between the 
average BBB spread during 2007Q3 and the BBB spread at the peak that 
episode (2008Q4) amounted to 431 basis points (Table 20).
---------------------------------------------------------------------------

    \216\ Federal Reserve staff calculated BBB spread using the U.S. 
BBB corporate yield, computed using the quarterly average of ICE 
BofAML U.S. Corporate 7-10 Year Yield-to-Maturity Index (ICE Data 
Indices, LLC, C4A4 series), and the quarterly average of the yield 
on 10-year U.S. Treasury notes, constructed by Federal Reserve staff 
based on the Svensson smoothed term structure model. See Svensson 
(1995), supra note 184.
---------------------------------------------------------------------------

    Figure 6 also illustrates that the peak range of 500 to 600 basis 
points implied by the proposed guide brackets the peak values of the 
BBB spread used in the past stress test scenarios (the dots are located 
within or on the borders outlined by the solid lines throughout the 
time span of the figure). In other words, the proposed guide is 
consistent with the Board's past stress test practices in determining 
the peak.

[[Page 51916]]

BILLING CODE 6210-01-C
    In its formulation of the annual scenarios, the Board could 
consider the overall level of cyclical systemic risk, or the current 
level of the BBB spreads as a contemporaneous indicator of uncertainty 
and financial stress. As discussed in Section IX.F of this 
Supplementary Information, the Board expects to calibrate the increment 
in the BBB spreads based on its views of the status of cyclical 
systemic risk. Specifically, the Board would be more likely to set the 
BBB spreads peak value at the higher end of the range if the Board 
expects that cyclical systemic risks are high (as it would be after a 
sustained long expansion), and alternatively would be more likely to 
set the peak value to the lower end of the range if cyclical systemic 
risks are low (as it would be in the earlier stages of a recovery), 
provided doing so remained consistent with the goal of ensuring that 
firms were properly capitalized to withstand severe economic and 
financial conditions. This might result in a scenario that is more 
severe than normal if the Board expects that cyclical systemic risks 
were increasing in a period of sustained robust expansion.
---------------------------------------------------------------------------

    \217\ Calculated using data from ICE Data Indices, LLC; the 
quarterly average of the yield on 10-year U.S. Treasury notes, 
constructed by Federal Reserve staff based on the Svensson smoothed 
term structure model; and Federal Reserve staff estimates. See 
Svensson (1995), supra note.
---------------------------------------------------------------------------

    Conversely, it would also allow the Board to specify a scenario 
that is less severe than normal in an environment where systemic risks 
appeared subdued, such as in the early stages of a recovery. The lower 
end of the increase range could also be appropriate when underlying 
market uncertainty and financial stress start to recede and higher-
than-usual credit losses stemming from previous elevated levels of the 
BBB spreads were either already realized--or are in the process of 
being realized--and thus removed from firms' balance sheets. This 
choice would consider that the scenario does not add unduly to 
remaining stress, thereby exacerbating the initial adverse shock, and 
it would be particularly appropriate if the Board judges that firms are 
already taking steps to reduce their risk; for instance, by potentially 
restricting lending to otherwise qualified borrowers.\218\
---------------------------------------------------------------------------

    \218\ Evidence of market uncertainty and financial stress 
receding could include decreased defaults in public bond markets, 
strong stock market performance or positive economic news related to 
GDP, unemployment or nonfarm payroll. Evidence that credit losses 
are being realized could include elevated charge-offs on loans and 
leases or loan-loss provisions in excess of gross charge-offs.
---------------------------------------------------------------------------

Alternative Peak Guide Option
    As an alternative, the Board also considered a guide that would 
choose a peak level as a maximum between 600 basis points and an 
increase from the jump-off value by 100 basis points. The justification 
for considering this peak calibration is as follows. Unlike the 
proposed guide, the alternative allows for less discretion and 
therefore would provide more certainty to firms and to market 
participants about the severity of the stress test each year. However, 
the Board considered the importance of ensuring that the chosen 
calibration would be sufficiently severe, because, as noted above, 
insufficiently severe stress tests can undermine the credibility of the 
results. Therefore, to attain adequate scenario severity for this 
option, the Board considered the peak calibration level of 600 basis 
points--the value corresponding to the BBB spread peak observed during 
the 2007-2009 financial crisis and the upper bound of the range 
considered for the proposed guide. This alternative guide could be less 
desirable as it is less flexible and may end up being too severe, 
especially during economic downturns, when the proposed guide would 
offer the flexibility to choose a lower peak from the range that could 
avoid adding sources of procyclicality in the results.
    Consider the application of the alternative guide in 2013-2024 
against the peaks of past scenarios and the proposed guide. Given the 
initial conditions in this time period, the alternative guide would 
prescribe the 600 basis points for the peak value in all quarters of 
the considered time span. Compared with the past stress tests,

[[Page 51917]]

such prescriptions are often more severe, resulting in the peaks that 
can be as much as 100 basis points higher than those of the past stress 
tests.
    Although the proposed and the alternative guides are both 
discussed, and the Board views the alternative guide as reasonable, it 
was judged to be inferior to the proposed guide as discussed in this 
section. The purpose of the alternative guide discussion is to invite 
comment on a reasonable alternative considered by the Board and to 
transparently lay out the Board's present arguments for choosing the 
proposed guide.

    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the peak and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The guide stipulates that 
the peak level in the scenario would be reached in quarter 3 or quarter 
4, which is consistent with historical observations. In post-war 
recessions, the BBB spread reached its peak in quarter 4 (on average), 
whereas the 2007-2009 financial crisis yields a peak in quarter 2 (see 
Table 20). The empirical literature that studies responses of corporate 
spreads to shocks (e.g., unexpected increases in uncertainty or 
financial riskiness) often documents a delayed peak. For instance, the 
response of the corporate spread to an uncertainty shock can peak after 
month 6 (into quarter 3) in the U.S. data.\219\ In the past stress test 
scenarios, the peak was also reached in quarter 4, on average.
---------------------------------------------------------------------------

    \219\ See Caldara (2016), supra note . The delayed peak feature 
is particularly prominent for the Jurado et al. (2015) measure of 
uncertainty--a widely accepted measure in this literature. K. Jurado 
et al., Measuring Uncertainty, 105 Am. Econ. Rev. 1177-1216 (2015).
---------------------------------------------------------------------------

    The Board expects that the timing of the start of the stress period 
should sometimes differ from the start date of the recession determined 
by the NBER. For potentially fast-moving variables (such as BBB spread, 
equity prices or VIX), the Board times the onset of the stress period 
during the 2007-2009 Financial Crisis based on the Lehman Brothers 
bankruptcy on September 15, 2008. This event is widely considered to be 
the most significant of the events that roiled financial markets during 
the 2007-2009 Financial Crisis.\220\ As stress test data operate at 
quarterly frequency, the Board's timing of this event for purposes of 
dating the peak of the BBB corporate spread is in 2008Q3. Indeed, the 
BBB corporate spread remained largely flat between 2008Q1 and 2008Q2, 
rising somewhat in 2008Q3 (because the Lehman Brothers bankruptcy 
occurred close to the end of the quarter, it had little effect on the 
quarterly average) before increasing sharply to the observed maximum in 
2008Q4.\221\ Therefore, the focus on the Lehman Bankruptcy as the 
triggering event is more consistent with the stress test scenario 
narrative in which a financial shock sets the stress test scenario 
dynamics in motion than the NBER recession date.
---------------------------------------------------------------------------

    \220\ See, e.g., R. Wiggins et al., The Lehman Brothers 
Bankruptcy A: Overview, 1 Journal of Financial Crises 39-62 (2019).
    \221\ Demonstrated by the calculation of the BBB spread over 
time using the U.S. BBB corporate yield, computed using the 
quarterly average of ICE BofAML U.S. Corporate 7-10 Year Yield-to-
Maturity Index (ICE Data Indices, LLC, C4A4 series), and the 
quarterly average of the yield on 10-year U.S. Treasury notes, 
constructed by Federal Reserve staff based on the Svensson smoothed 
term structure model. See Svensson (1995), supra note 184.
---------------------------------------------------------------------------

Trajectory to Peak Value
    To reach the peak spread value, the guide prescribes that the 
highest share of the spread increase (about 60 to 80 percent) occurs in 
the first quarter of the scenario. Such frontloading of the spread 
increase is consistent with the historical evidence and academic 
literature.\222\ For instance, in the 2007-2009 financial crisis, the 
largest increase in the spread (about 67 percent of the jump-off. A 
very similar result emerges when considering the Enron/Dotcom stress 
episode and 1990 bond market stress episode.\223\ On average (across 
all three bond market stress episodes), about 66 percent of the 
increase to the peak in the spread was realized in a single quarter 
after the onset of the stress episode. After quarter one and until the 
peak is reached, the guide stipulates a smooth trajectory with half of 
the remaining adjustment made in quarter two and with the rest of the 
adjustment made either in quarter three (when the peak occurs in 
quarter three) or equally distributed between quarter three and four 
(when the peak occurs in quarter four). As an example, if the increase 
share in the first quarter was around 60 percent, then the adjustment 
in quarter two would be about 20 percent with the remaining 20 percent 
in quarter three (if the peak is in quarter three) or with the 
remaining distributed approximately 10 percent each in quarter three 
and four (if the peak is in quarter four). This simple adjustment rule 
mimics a hump-shaped response of the corporate spread to shocks, a 
feature well-documented in the empirical literature.\224\
---------------------------------------------------------------------------

    \222\ In the academic literature, spreads are well-known to be 
contemporaneous indicators that move the most at the onset of a 
stress event or crisis. For instance, Krishnamurthy (2025) documents 
rapid changes in spreads at the onset of financial crises, whereas 
Bernanke (2005) classify spreads and stock market prices as ``fast-
moving'' variables that respond to shocks on impact. A.

Crisis, 80 J. of Fin. 1339-78 (2025) (``Krishnamurthy (2025)''); B.

Augmented Vector Autoregressive (FAVAR) Approach, 120 Q.J. of Econ.

evidence of such behavior of spreads in response to financial shocks 
and uncertainty shocks.

---------------------------------------------------------------------------

Mortgage Rate
    The stress test scenarios sets out trajectories for several 
variables, including the mortgage spread as proxied by the quarterly 
average of weekly series for the interest rate of a conventional, 
conforming, 30-year fixed-rate mortgage, obtained from the Freddie Mac 
Primary Mortgage Market Survey relative to the 10-year Treasury 
yield.\225\ For purposes of this guide, mortgage spread refers to the 
difference, in basis points, between mortgage and Treasury rates 
defined above.
---------------------------------------------------------------------------

    \225\ The 10-year Treasury yield is calculated using the 
quarterly average of the yield on 10-year Treasury notes by the 
Federal Reserve Board based on the Svensson smoothed term structure 
model. See Svensson (1995), supra note 184.
---------------------------------------------------------------------------

    In the supervisory stress test, the mortgage spread can act as both 
(i) an indicator of stress for certain important assets under the 
scenarios and (ii) a source of stress for firms subject to the 
supervisory stress test with substantial exposure to assets that are 
tied to mortgage spreads, such as mortgage loan portfolio or mortgage-
backed securities, which are reported by firms on FR Y-14M, Schedule A 
(First Lien) and FR Y-14Q, Schedule B (Securities). Firms subject to 
the supervisory stress test typically have substantial exposure to the 
assets referenced in the mortgage spread, and as a result, by 
incorporating the mortgage spread into scenarios, stress tests help 
ensure that firms are prepared for a wide range of market conditions, 
including periods of

[[Page 51918]]

elevated mortgage spreads, in part reflecting financial shocks and any 
associated economic downturn. This helps maintain the overall stability 
and resilience of the financial system.
    The Board uses a quarterly average of the mortgage rate spread in 
the stress test scenarios. Quarterly averages smooth out excessive (and 
potentially irrelevant) volatility that is present at weekly or monthly 
frequencies. Using quarterly averages strikes a balance between being 
sensitive enough to capture market trends and stable enough to avoid 
overreaction to market volatility that is not representative of 
underlying trends in housing markets or the broader economy.
    In determining the appropriate level of scenario severity, the 
Board adheres to scenario design principles discussed in Section IX.F 
of this Supplementary Information. While doing so, the Board also 
strives to avoid introducing additional sources of procyclicality into 
the financial system. In the context of the mortgage spread, these 
principles are applied in calibrating three key aspects of the guide: 
the trough value, the timing of the trough value, and the trajectory to 
trough. This approach helps ensure that the mortgage spread guide 
aligns with the established stress testing literature while mitigating 
potential systemic risks for the financial system.
    The rest of this section is organized as follows. First, Table 21 
provides an overview of the mortgage rate guide components, which is 
followed by a description of the peak component for the guide. The next 
subsection provides the data- and scenario-based rationale for the 
calibration of the peak component. A discussion of an alternative peak 
option follows in the next section, comparing the implementation and 
caveats to the proposed guide option. Finally, additional guide 
parameters (trough value timing and trajectory to the peak) and the 
rationale for their calibration are discussed.

a. Peak Value Component of the Guide
    The mortgage rate is expected to move such that its spread relative 
to the 10-year Treasury yield would increase from its jump-off level 
(i.e., the value of the variable in the quarter before the start of the 
scenario) to a range determined by that level plus 70 basis points to 
160 basis points, with a lower bound of 300 basis points.
Data- and Scenario-Based Rationale for the Peak Value
    In line with the guiding principles emphasized by the stress 
testing literature and discussed in Section IX.F of this Supplementary 
Information, the Board uses the behavior of the mortgage spreads during 
financial stress episodes, including the 2007-2009 financial crisis, to 
calibrate the guide for the mortgage spread in the supervisory stress 
test scenarios. In particular, the Board considers the behavior of the 
mortgage spread in three severe recessions, including the 2007-2009 
financial crisis, to calibrate the guide for mortgage spreads in the 
supervisory stress test scenarios. In particular, the calibration of 
the lower bound of 300 basis points in the guide is based on evidence 
from historical stress episodes along with the principle of 
conservatism. The average peak value for the mortgage spread observed 
in severe recessions has been 278 basis points (Table 22), ranging from 
225 to 380 basis points.\226\ In the 2007-2009 financial crisis, the 
peak mortgage spread measured about 249 basis points at a weekly 
frequency.\227\ The calibration of the lower bound of 300 basis 
points--a value that is slightly above the historical average during 
severe recessions--speaks to the guiding principle that adequate 
severity should be somewhat beyond historical experiences. In addition, 
setting a floor for the mortgage spreads at 300 basis points recognizes 
the fact that, not only do cyclical systemic risks build up at 
financial intermediaries during robust expansions, but that these risks 
are also easily obscured by a buoyant environment.
---------------------------------------------------------------------------

    \226\ A similar average peak value of 260 points is obtained 
from averaging across episodes of housing market stress, which 
include the 1973 recession along with the previously defined housing 
recessions (1980Q2-1985Q2, 1989Q4-1997Q1, 2005Q4-2012Q1). See 12 CFR 
252, Appendix A.
    \227\ The spread measure at weekly frequency is obtained as an 
average over daily values starting from Thursday of the previous 
week and ending on Wednesday of the next week. Accordingly, the 
value of approximately 249 basis points was reached in the calendar 
week ending on December 21, 2008. A close value of 248 basis points 
was reached in the calendar week ending on August 31, 2008.

---------------------------------------------------------------------------

[[Page 51919]]

[GRAPHIC] [TIFF OMITTED] TP18NO25.064

    The historical \228\ maximum value of the mortgage spread occurred 
in the 1980-1985 episode--in a high-inflation environment with high 
unemployment as well--and measured 404 basis points, based on quarterly 
averages of the spread. Weekly averages of the spread during this 
episode would result in a higher peak level of 541 basis points, which 
was reached in the calendar week ending on April 20, 1980 (Figure 7). 
Between 2022 and 2024, inflation accelerated, and the mortgage spread 
rose above the 2007-2009 peak, reaching a quarterly-frequency maximum 
of 284 basis points in 2023 Q2 (304 basis points at a weekly frequency, 
in the calendar week ending on May 28, 2023) despite a strong economy 
and well-functioning mortgage markets. Hence, guide calibration of the 
mortgage spread should account for conditions in the housing market, 
including interest rate volatility, and the phase of the business cycle 
as described above, as well as the level of inflation and inflation 
expectations at the jump-off quarter to elucidate their effect on 
firms' balance sheets.

    \228\ Quarterly average of weekly series for the interest rate 
of a conventional, conforming, 30-year fixed-rate mortgage is 
obtained from the Primary Mortgage Market Survey of the Federal Home 
Loan Mortgage Corporation. Quarterly average of the yield on 10-year 
Treasury notes is constructed by the Federal Reserve Board based on 
the Svensson smoothed term structure model. See Svensson (1995), 
supra note 184. Data also derived from Federal Reserve staff 
calculations.

---------------------------------------------------------------------------

    In its formulation \229\ of the annual scenarios, the Board could 
consider the overall level of cyclical systemic risk, or the current 
level of the mortgage spreads as a contemporaneous indicator of 
uncertainty and financial stress. As discussed in Section IX.F of this 
Supplementary Information, the Board expects to calibrate the increment 
in the mortgage spreads based on its views of the status of cyclical 
systemic risk. Specifically, the Board would be more likely to set the 
mortgage spread peak value at the higher end of the range if the Board 
expects that cyclical systemic risks are high (as it would be after a 
sustained long expansion), and alternatively would be more likely to 
set the peak value to the lower end of the range if cyclical systemic 
risks are low (as it would be in the earlier stages of a recovery), 
provided doing so remained consistent with the goal of ensuring that 
firms were properly capitalized to withstand severe economic and 
financial conditions. This might result in a scenario that is more 
intense than normal if the Board expects that cyclical systemic risks 
were increasing in a period of sustained robust expansion. Conversely, 
it would also allow the Board to specify a scenario that is less 
intense than normal in an environment where systemic risks appeared 
subdued, such as in the early stages of a recovery. The lower end of 
the range could also be appropriate when underlying market uncertainty 
and financial stress start to recede and higher-than-usual credit 
losses stemming from previously elevated levels of mortgage spreads 
were either already realized or are in the process of being realized, 
and thus removed from firms' balance sheets. This choice would consider 
that the scenario does not add unduly to remaining stress, thereby 
exacerbating the initial adverse shock, and it would be particularly 
appropriate if the Board judges that firms are already taking steps to 
reduce their risk--for instance, by potentially restricting lending to 
otherwise qualified borrowers.\230\

See Svensson (1995), supra note 184. Data also derived from Federal 
Reserve staff estimates.
    \230\ Evidence of market uncertainty and financial stress 
receding could include stronger lending growth, an easing of lending 
standards, strong stock market performance or positive economic news 
related to GDP, unemployment, or nonfarm payroll. Evidence that 
credit losses are being realized could include elevated charge-offs 
on loans and leases or loan-loss provisions in excess of gross 
charge-offs.
---------------------------------------------------------------------------

    Consider the application of the range component of the guide (70 to 
160 basis points from the jump-off value) illustrated in Figure 8 
(solid lines) for 2014-2025 stress test cycles. This time period is 
illustrative as it contains various stages of the business and 
financial cycle (normalization after the 2007-2009 financial crisis, 
the COVID-19 pandemic and the normalization after it in a higher-
inflation environment). Accordingly, the initial conditions in this 
period are quite representative. While the lower bound of the range 
(300 basis points) was explained above, the application of the upper 
part of the range results in values from 300 basis points to 440 basis 
points, with the higher values achieved in 2022-2024, a period of 
higher inflation. Per the discussion above, these values, while being 
severe, do not deviate too far from historically observed values. And 
consistently with historical experiences, these values also reflect the 
inflation environment.

BILLING CODE 6210-01-C
    To illustrate \231\ the implications of the guide, the Board 
applies it to recent historical data and compares the implied peak 
prescriptions with the corresponding peaks from past stress test 
scenarios (Figure 8). From 2013Q1 until 2019Q4, the stress test peak 
values, depicted by the dots, were quantitatively close to the upper 
end of the range of the proposed guide, depicted by the solid lines 
(Figure 8). From the onset of the COVID-19 pandemic in 2020 through 
2021, the stress test peaks were mostly within the bands of the 
proposed guide, while in 2022-2024 the stress test peaks were located 
at or very close to the lower end of the range suggested by the 
proposed guide. Summing up, comparison of the guide-implied peaks with 
the past stress test peak values shows that the guide is broadly 
consistent with past scenario values. The range of the guide should 
allow the Board to account for risks that are apparent in relevant 
indicators of economic and financial conditions and constrain the peak 
to historically plausible bounds during normal periods, while adjusting 
to future periods in which spreads may move toward record levels.
---------------------------------------------------------------------------

    \231\ Data derived from Primary Mortgage Market Survey of the 
Federal Home Loan Mortgage Corporation and Federal Reserve staff 
estimates.
---------------------------------------------------------------------------

Alternative Peak Guide Option
    As an alternative, the Board also considered a guide that would 
choose a peak level as a maximum between 300 basis points and an 
increase from the jump-off value by 100 basis points. A comparison of 
the alternative and the proposed guides in 2013-2024 illustrates 
episodes when the alternative guide deviates from the proposed guide. 
As the alternative guide has a flat increment regardless of the 
underlying conditions, it would propose systematically lower peak 
values in the pre-pandemic period and systematically higher values in 
the post-pandemic period, when compared with the stress test peaks. 
Additionally, following this alternative guide would not allow the 
Board to respond to risks not already reflected in the current level of 
the mortgage spread.
    Although the proposed and the alternative guides are both 
discussed, and the Board views the alternative guide as reasonable, the 
benefits to the public from increased predictability in the alternative 
guide are considered to be outweighed by the added flexibility to 
reflect risks related to mortgage finance that are apparent in relevant 
indicators of economic and financial conditions or to avoid adding 
additional sources of procyclicality in the proposed guide. The purpose 
of the alternative guide discussion is to invite comment on a 
reasonable alternative considered by the Board and to transparently lay 
out the Board's present decision making in choosing the proposed guide.
b. Additional Guide Parameters and Rationale Behind Them
Peak Value Timing
    In general, the entire 13-quarter trajectory of stress test 
variables is important as it ultimately affects implied firm losses. 
The value of the peak and its timing signify the magnitude and timing 
of the most severe point in this trajectory. The proposed guide 
stipulates that the peak level in the scenario would be reached in 
quarters 3 to 4, which is consistent with historical observations and 
past severely adverse scenarios (Table 22). The proposed guide sets a 
range of peak timings between 3 and 4 quarters, whereas the alternative 
guide eliminates this flexibility and stipulates a peak in quarter 3. 
Keeping the magnitude of the peak constant, a more delayed peak timing 
generally results in less severity of the overall path, as a less 
abrupt worsening in conditions and credit quality gives firms and 
mortgage borrowers more time to adjust to the shock. In contrast, an 
earlier peak timing would increase the scenario severity.
    For the proposed guide, a range in the timing (quarter 3 or quarter 
4) is used as an additional lever (together with the peak magnitude 
range) to avoid adding

[[Page 51922]]

sources of procyclicality in the stress test. An earlier peak timing 
would increase the scenario severity. The factors that the Board would 
consider in setting the timing of the peak are the same as those 
discussed above influencing the level of the peak.
Trajectory to Peak Value
    To reach the peak spread value, the guide prescribes that the 
highest share of the spread increase (50 to 70 percent) occurs in the 
first quarter of the scenario. After quarter one and until the peak is 
reached, the guide stipulates a smooth trajectory. Such frontloading of 
the spread increase is consistent with the historical evidence and 
academic literature.\232\ Averaging across all financial stress 
episodes, the share of the mortgage spread increase that occurs in the 
first quarter after the onset of the stress is about 60 percent; in 
other words, 60 percent of the distance from the jump-off point to the 
peak is covered in the first quarter. This number is quantitatively 
similar to the past stress test scenarios in 2013-2025, where on 
average the corresponding share measures 64 percent. Averaging across 
severe historical episodes in the data yields a share of 73 percent. At 
the same time, there are severe episodes with a somewhat smaller 
increase in the share occurring in the first quarter. For instance, the 
severe episode surrounding the 1981 recession measured 47 percent of 
the mortgage spread increase in the first quarter. Hence, both the 
guide calibration (over 50 percent) as well as the average obtained 
across the mortgage spread paths in 2013-2025 stress test scenarios (64 
percent) lie within historically plausible bounds.
---------------------------------------------------------------------------

    \232\ See supra note 222.
---------------------------------------------------------------------------

International Variables
    As described in the Scenario Design Policy Statement, a scenario 
that targets all specific risk factor groups includes judgement on the 
projected paths of selected international variables. Recessions that 
occur simultaneously across countries are an important source of stress 
to the balance sheets of firms with notable international exposures but 
are not a typical feature of the international economy even when the 
United States is in recession. As a result, simply adopting the typical 
path of international variables in a severe U.S. recession would likely 
underestimate the risks stemming from the international economy. 
Consequently, an approach that relies on both judgement and insights 
from economic models informs the path of international variables. As 
part of the review of the scenario design framework, the Board has 
developed simple quantitative guides for the proposed paths of the 
international variables used in the severely adverse scenario of the 
supervisory stress test. Consistent with the Scenario Design Policy 
Statement, the international component of the stress test scenarios 
contains the path for real GDP, consumer price inflation, and the 
nominal exchange rate for four country blocs: the euro area, the U.K., 
Japan, and Developing Asia.\233\ These economies capture the majority 
of the foreign exposure of U.S. banks.
---------------------------------------------------------------------------

    \233\ For the purpose of the supervisory stress tests, the Board 
defines Developing Asia as China, India, Hong Kong, South Korea, and 
Taiwan. Aggregate variables for this bloc (GDP, inflation, and the 
nominal exchange rate) are obtained by weighting country-specific 
variables by their relative share of the total nominal GDP 
(expressed in U.S. dollars).
---------------------------------------------------------------------------

    The following guides apply to each international variable:
     A peak/trough value, which represents the extreme value 
(either peak or trough, depending on the variable) that is typically 
reached in the severely adverse scenario. For all variables the peak/
trough is reached after 4 quarters.
     An end value for the last period in the scenario, that is 
13 quarters after initial impact.
     A scenario path, which describes the path of international 
variables from the jump-off value to the peak/trough value and then to 
the end value.
     A scenario range, which specifies by how much each 
variable can deviate from the scenario path to adapt to relevant 
changes in banking, macroeconomic, or other conditions.
a. Overview of Approach
    In designing the paths of the international variables in the 
severely adverse scenario, the Board opted to follow a prescriptive 
approach that is informed by the experience of the 2007-2009 financial 
crisis. Given its global repercussions, the 2007-2009 financial crisis 
is a useful benchmark for the economic effects of a large global 
financial shock.
    To generate the proposed paths of GDP and inflation in the four 
economic regions for the severely adverse scenario, the Board first 
computed the distance between the realized outcomes of GDP and 
inflation during the 2007-2009 financial crisis from the baseline 
forecasts prior to the onset of the 2007-2009 financial crisis. These 
baseline forecasts were derived from publicly available forecasts from 
the Blue Chip Economic Indicators and the IMF World Economic Outlook 
(WEO).\234\ The Blue Chip and WEO forecasts provide values for year-
over-year real GDP growth and inflation. To forecast quarterly GDP 
growth rates and inflation rates, quarterly values are first derived 
from the annual growth rates using linear interpolation; then a 
Hodrick-Prescott filter is used to smooth the path of GDP and inflation 
across the forecast period.\235\ Based on this procedure, the Board 
specifies guides for the values of the variables of interest. These 
values are usually reached in the scenario, but the Board reserves the 
right to depart from these values within specified ranges.
---------------------------------------------------------------------------

    \234\ The Blue Chip data provide forecasts over a two-year 
horizon and are updated at a monthly frequency. The WEO data provide 
forecasts over a six-year horizon, which are updated biannually in 
April and September/October each year. To produce the baseline 
scenario, the Blue Chip forecasts are used for the first two years, 
whereas the WEO forecasts are used for the remaining years.
    \235\ The Hodrick-Prescott filter is an empirical tool that can 
be employed to remove the cyclical component of a time series data. 
This technique was developed by Whittaker (1923) and popularized in 
economics by Hodrick and Prescott (1997). See E. Whittaker, ``On a 
New Method of Graduation.'' Proceedings of the Edinburgh 
Mathematical Association. 41: 63-75 (1923), https://doi.org/10.1017%2FS0013091500077853; R. Hodrick & E. Prescott, Postwar U.S. 
Business Cycles: An Empirical Investigation, 29 J. of Money, Credit 
& Banking 1-16 (Feb. 1997), https://doi.org/10.2307/2953682.
---------------------------------------------------------------------------

    The data for the euro area, the U.K., and Japan were aggregated to 
obtain identical guides for GDP and inflation for these Advanced 
Foreign Economies (AFEs). The Board favored identical guides for these 
regions to prevent possible credit allocation incentives that could 
arise if guides differed systematically between the AFEs. However, 
identical guides do not imply that the actual severely adverse scenario 
features identical paths for the euro area, the U.K., and Japan. The 
scenario paths of the three regions can vary with the given ranges.
    The key elements of the international guides derived from this 
procedure are summarized in Table 23; Figure 9 shows the behavior of 
the variables of interest during the 2007-2009 financial crisis from 
which the guides are derived. Detailed explanations and alternative 
considerations are provided thereafter. For GDP, the deviation is 
computed as percentage change from the baseline real GDP level. For 
inflation, the deviation is computed as percentage point difference 
from the baseline path of inflation. For exchange rates, the guide is 
expressed in terms of percent deviation from the jump-off point.

[[Page 51923]]

[GRAPHIC] [TIFF OMITTED] TP18NO25.067

    Table 23 also provides ranges for each variable to allow for 
flexibility: This flexibility enables judgment to be exercised to 
capture the possibility that the foreign economies might react 
differently to financial stress, either because of changes in the 
global macroeconomic landscape or in country-specific vulnerabilities.
    The prescriptive approach for the international variables in the 
severely adverse scenario yields guides that are qualitatively and 
quantitatively reasonable based on the Board's judgment and broadly 
accepted models of international economies.\236\ The Board opted for 
the more prescriptive approach because the advantages of increased 
transparency and simplicity outweighed the disadvantage of less 
flexibility.

integrated policy framework. IMF WP/20/122 (2020).
---------------------------------------------------------------------------

b. GDP
Trough Value
    The magnitude of the prescribed economic downturn in the specified 
foreign economies is informed by the deterioration in foreign economic 
activity which occurred between 2008Q1 and 2009Q1. In particular, the 
trough value for GDP is obtained by considering the deviation of the 
real GDP level in 2009Q1 from a baseline path derived from the April 
2008 IMF WEO forecast.\237\ This approach implies that, four quarters 
after jump-off, the GDP levels in the euro area, the U.K., and Japan 
are 7.5 percent below the baseline scenario.\238\ In Developing Asia, 
GDP growth declines until GDP reaches a level 3 percent below baseline. 
These values are in line with the behavior of real GDP reported in the 
top panel of Figure 9.
---------------------------------------------------------------------------

    \237\ The April 2008 WEO provides forecasts for annual GDP 
growth and for annual inflation between 2008 and 2013. Blue Chip 
forecast for international variables are not available until 2009. 
The baseline for quarterly GDP growth rates and inflation, over the 
period 2008Q2 until 2011Q2, is generated using the same procedure 
employed to create the baseline scenario: first, quarterly values 
for the GDP level are obtained by linearly interpolating the annual 
growth rates available in the WEO forecast, and then a Hodrick-
Prescott filter is used to smooth the GDP level path across the 
forecast period.
    \238\ This value is in line with the average deviation from 
baseline across these advanced economies in 2009Q1, when weighting 
the deviations from baseline by the nominal GDP (in U.S. dollars) in 
each country bloc in 2007.
---------------------------------------------------------------------------

End Value
    In the euro area, the U.K., and Japan, the level of GDP at the end 
of the severely adverse scenario deviates from the corresponding value 
in the baseline (13 quarters after initial impact) by the same 
magnitude as the trough value of GDP deviates from the corresponding 
value in the baseline (4 quarters after initial impact). This 
assumption implies that, in line with the experience of the 2007-2009 
global financial crisis, after reaching the trough, GDP in the AFEs 
grows at the same rate as in the (pre-crisis) baseline. The guide 
proposes that GDP recovers more quickly in developing Asia, returning 
to the GDP baseline in levels at the end of the scenario, in line with 
the evidence from 2011Q2. These GDP paths are consistent with Figure 9 
and with empirical evidence which suggests that advanced economies 
suffer very persistent output losses following a financial crisis, 
while developing economies experience less severe slowdowns.\239\
---------------------------------------------------------------------------

    \239\ See, e.g., V. Cerra & S. Saxena, Growth Dynamics: The Myth 
of Economic Recovery, 98 American Economic Review 439-57 (2008); 
[Ograve]. Jord[agrave] et al., When credit bites back, 45 J. of 
Money, Credit & Banking 3-28 (2013); M. Laeven & M. Valencia, 
Systemic Banking Crises Revisited, International Monetary Fund, WP/
18/206 (2018).
---------------------------------------------------------------------------

Path
    Real GDP reaches the reference trough four quarters after the jump-
off date and then gradually converges to the end value of the scenario. 
After reaching the trough, the AFEs experience a similar GDP growth 
rate in the scenario as in the baseline, whereas Developing Asia grows 
faster in the scenario to catch up with the level of GDP in the 
baseline. The path of GDP is created with a two-step procedure similar 
to the one used to generate the baseline scenario. First, the series is 
linearly interpolated between the jump-off value and the

[[Page 51924]]

trough value and from the trough value to the end value. Then, a 
Hodrick-Prescott filter is used to smooth the GDP path over the 
duration of the scenario. This approach generates a smooth path for GDP 
consistent with business cycle dynamics.
Range
    The path described above captures the GDP dynamics during the 2007-
2009 financial crisis. In determining the magnitude of the 
international shock in the severely adverse scenario, the Board would 
consider several factors, including the current economic performance of 
foreign economies, the risks posed by country-specific vulnerabilities, 
and the scope for countercyclical policy actions in each country bloc. 
For example, in periods of sub-par foreign economic performance, the 
Board would likely reduce the magnitude of the shock, whereas when 
foreign growth is particularly strong, the magnitude of the shock would 
be increased. In addition, the allocation of shocks across blocs can be 
altered to highlight relevant country-specific risks. This strategy is 
implemented by increasing or decreasing the severity of the shock, as 
measured by the deviation of GDP from baseline at the scenario trough, 
by at most 2.5 percent.\240\ As a result, at the trough, real GDP can 
fall between 5 and 10 percent below the baseline in advanced foreign 
economies, bracketing the real GDP outcomes of the three AFEs in the 
2007-2009 financial crisis. For Developing Asia, real GDP can fall 
between 0.5 and 5.5 percent below the baseline. These adjustments are 
performed while keeping the overall stress on foreign economies, as 
measured by the average GDP deviation from baseline at the trough, 
within a range of 4 to 9 percent.\241\
---------------------------------------------------------------------------

    \240\ This value is in line with the average standard deviation 
of four-quarter GDP growth across the four country blocs, computed 
over the pre-COVID-19 historical sample. When adjusting the 
reference peak/trough value, the reference end value is adjusted 
proportionally, to keep the ratio with the trough value constant.
    \241\ Total effect on the foreign economies is computed 
weighting the deviations from baseline in each country bloc by the 
bloc's nominal GDP (in U.S. dollars) in the year preceding the jump-
off date. The range of -4 to -9 percent is centered around -6.5 
percent--that is, the average deviation from baseline across the 
foreign economies in 2009Q1.

---------------------------------------------------------------------------

c. Inflation
Trough Value
    Inflation is assumed to decline below the baseline scenario for the 
first four quarters of the simulation, consistent with the demand-
driven decline in GDP growth over the same period. This behavior is 
broadly in line with the historical evidence between 2008Q1 and 2009Q1 
for the four country blocs. The maximum decline in inflation is 
calibrated to reflect the difference between the realized rate of 
inflation and the one derived from the April 2008 IMF WEO forecast for 
2009Q1 (middle panel of Figure 9Figure). This method provides that, 
four quarters after the jump-off date, inflation is below baseline by 
about 3 percentage points in the euro area, the UK, and in Japan, and 
by 5 percentage points in Developing Asia.\242\
---------------------------------------------------------------------------

    \242\ The decline in inflation in the Euro area, UK, and Japan 
is in line with the average deviation from baseline across these 
advanced economies in 2009Q1, when weighting the deviations from 
baseline by the nominal GDP (in U.S. dollars) in each country bloc 
in 2007.
---------------------------------------------------------------------------

End Value
    After reaching the trough, inflation gradually returns to baseline 
by the 13th quarter of the simulation. This inflation path is 
consistent with the evidence from the 2007-2009 financial crisis, when 
inflation returned to, or even surpassed, the WEO baseline by 2011. In

[[Page 51926]]

addition, academic research suggests that financial crises typically do 
not have large or persistent effects on inflation.\243\
---------------------------------------------------------------------------

    \243\ See, e.g., M. Schularick & A. Taylor, Credit Booms Gone 
Bust: Monetary Policy, Leverage Cycles, and Financial Crises, 1870-
2008, 102 Am. Econ. Rev. 1029-61 (2012); S. Gilchrist et al., 
Inflation Dynamics during the Financial Crisis, 107 Am. Econ. Rev. 
785-823 (2017).
---------------------------------------------------------------------------

Path
    The path for inflation is obtained by using the same strategy 
employed for GDP, which combines linear interpolation and a Hodrick-
Prescott filter.
Range
    If the path of GDP is different from the reference path, the path 
for inflation will be adjusted to preserve the same ratio between the 
deviation of GDP and the deviation of inflation from baseline under the 
reference path--the values of these ratios are 2.5 for advanced foreign 
economies and 0.6 for Developing Asia.\244\ As a result, inflation 
declines between 2 percentage points and 4 percentage points below 
baseline in the advanced foreign economies, and between 0.8 percentage 
points and 9 percentage points below baseline in Developing Asia.
---------------------------------------------------------------------------

    \244\ This value is equal to the ratio between the deviation of 
real GDP from baseline and the deviation of inflation from baseline 
at the trough in the international guides, that is the ratio between 
7.5% and 3% for advanced foreign economies and the ratio between 3 
percent and 5 percent for Developing Asia.
---------------------------------------------------------------------------

d. Exchange Rates
Trough/Peak Value
    The Board assumes that over the first four quarters of the 
simulation the U.S. Dollar experiences a 15 percent appreciation 
against the Euro and the British Pound. This appreciation is in line 
with the change in the Nominal Advanced Foreign Economies U.S. Dollar 
Index between 2008Q1 and 2009Q1 (bottom left panel of Figure 9).\245\ 
Over the same period, the U.S. Dollar appreciates by 15 percent also 
against the exchange rate for Developing Asia, in line with the 
fluctuation in the Nominal Emerging Market Economies U.S. Dollar Index 
between 2008Q1 and 2009Q1 (see bottom right panel of Figure 9).\246\ 
Consistent with the evidence between 2008Q1 and 2009Q1, the U.S. Dollar 
experiences a mild 1 percent depreciation against the Japanese Yen, 
which is typically considered a safe-haven currency, a currency which 
retains its value during times of global economic stress.\247\

    \247\ See, e.g., M. Botman, et al., The Curious Case of the Yen 
as a Safe Haven Currency: A Forensic Analysis, International 
Monetary Fund, WP/13/228 (2013). The Yen/USD exchange rate went from 
approximately 99.9 at the end of 2008Q1 to 99.15 at the end of 
2009Q1, a decline of about one percent.
---------------------------------------------------------------------------

End Value
    Exchange rates gradually reach their peak/trough and then revert 
back to their jump-off values by the end of the scenario horizon.
Path
    The path for the exchange rate is obtained by using the same 
strategy employed for GDP and inflation, which combines linear 
interpolation and a Hodrick-Prescott filter.
Range
    For exchange rates, which are highly volatile and only weakly 
linked to macroeconomic fundamentals, the Board can adjust the maximum 
fluctuation of each of the four foreign currencies within a range of 
plus or minus 10 percent from the reference peak/trough value.\248\ For 
each country bloc, the magnitude of the depreciation is adjusted 
depending on the realized change in the exchange rate in the year 
preceding the jump-off date. For example, if over the past year the 
dollar has already appreciated by 5 percent against the euro, the Board 
would lower the appreciation rate in the scenario from 15 percent to 10 
percent.
---------------------------------------------------------------------------

    \248\ This value is in line with the average standard deviation 
of 4-quarter changes in the exchange rates of the four country 
blocs, computed over the pre-COVID-19 historical sample.
---------------------------------------------------------------------------

e. Alternative Considerations
    The Board considered a range of different approaches to derive the 
guides for the international variables in the severely adverse 
scenario. First, distinct instead of common guides for GDP and 
inflation for each of the AFEs were explored. Following the methodology 
explained in Section IX.F of this Supplementary Information, the trough 
values for GDP during the 2007-2009 financial crisis were 6 percent 
below baseline in both the euro area and the U.K., and 10 percent below 
baseline in Japan. For inflation, the trough values in the 2007-2009 
financial crisis were 3 percent below baseline in the euro area, 2 
percent below baseline in the U.K., and 4.5 percent below baseline in 
Japan. The Board decided against using region-specific guides for the 
AFEs, as systematic differences in the guides across regions could 
affect credit allocations. However, the issued guides still allow for 
region-specific paths in the severely adverse scenario within the 
specified ranges to reflect region-specific circumstances when 
desirable. The Board may also use the specified ranges to raise or 
lower the sensitivity of all regions at the same time in the severely 
adverse scenario.
    Second, the Board examined other global or regional economic 
downturns of significance in addition to the 2007-2009 financial crisis 
to refine its guides for the international variables of the adverse 
scenario. There are only a few global recessions in recent history but 
none of them--besides the 2007-2009 crisis--were driven by financial 
factors. The COVID-19 recession of 2020 led to a sharper contraction in 
global economic activity than the 2007-2009 financial crisis but did 
not result in persistent financial stress. One distinct feature of the 
2007-2009 financial crisis was the resilience of Developing Asia where 
GDP dropped by only 3 percent relative to baseline. Only a decade prior 
to the 2007-2009 financial crisis, several countries in Developing Asia 
had experienced negative doubled-digit GDP growth rates as part of the 
1997 Asian Financial Crisis. Based on the experience of the 1997 Asian 
Financial Crisis, the Board considered a lower trough value for 
Developing Asia. However, the Board decided against this approach for 
several reasons. China was generally unaffected by the Asian Financial 
Crisis and maintained its high GDP growth rate throughout the crisis, 
significantly increasing the regional GDP growth rate during this 
period despite the sharp declines experienced elsewhere in the region. 
In addition, the countries that were most affected by the Asian 
Financial Crisis changed to more robust economic policies--switching 
from fixed/managed exchange rates to flexible inflation targeting and 
from policies that implied large current account deficits to policies 
that led to surpluses. Finally, the Board looked to the euro area debt 
crisis for additional guidance. But since this crisis directly followed 
the 2007-2009 financial crisis no additional insight for the design of 
the severely adverse scenario was obtained that was not already 
embedded in the analysis of the 2007-2009 financial crisis. In the 
interest of transparency and simplicity, the Board decided to adopt the 
findings derived solely from the 2007-2009 financial crisis but added 
flexibility by allowing ranges for variables.

[[Page 51927]]

H. Global Market Shock

Design of the Global Market Shock
    The global market shock component comprises a large set of 
financial risk factors and associated hypothetical shocks to those risk 
factors. The Board considers emerging and ongoing areas of financial 
market vulnerabilities in the development of the global market shock 
component, informed by financial stability reports, supervisory 
information, and internal and external assessments of potential sources 
of distress such as geopolitical, economic, and financial market 
events. Financial risk factor shocks are calibrated based on assumed 
time horizons that reflect several scenario design considerations. The 
Board also considers liquidity characteristics of the different asset 
classes that constitute certain risk factors. These liquidity horizons 
approximate the variation in speed at which banks could reasonably 
close out, or effectively hedge, the associated risk exposures in the 
event of market stress.
    The chosen risk factors of the global market shock scenario are 
important to specifying how a stress scenario unfolds across financial 
markets and capturing salient risks within the banking system. These 
include, but are not limited to:
     Public equity returns from key advanced economies and from 
developing and emerging market economies, along with selected points 
along term structures of equity option-implied volatilities;
     Exchange rates of foreign currencies, along with selected 
points along term structures of foreign exchange option-implied 
volatilities;
     Government yields at selected maturities (e.g., 10-year 
U.S. Treasuries), swap rates, and other types of interest rates for key 
advanced economies and from developing and emerging market economies;
     Implied volatilities on interest rate options for selected 
maturities and expiration dates, which are key inputs to the pricing of 
interest rate derivatives;
     Futures prices at various expiration dates for commodity 
products such as energy, oil, metals, and agricultural products; and
     Credit spreads or prices for selected credit-sensitive 
products, including corporate bonds, credit default swaps (CDS), 
securitized products, sovereign debt, and municipal bonds.
    The global market shock is typically applied to positions held by 
the firms on a given as-of date, reflecting a hypothetical 
instantaneous ``shock'' to a large number of risk factors that 
determine the mark-to-market values of trading positions. Additionally, 
the global market shock in a given annual severely adverse scenario is 
a standardized set of market shocks that apply to all of the firms with 
significant trading activities. The selection of a single date, and a 
single global market shock, has tended to enhance the operational 
consistency and simplicity of the annual supervisory stress test, while 
managing burden on reporting firms.
    The Board is considering enhancements to the design of the global 
market shock in the annual stress test to improve the stress test's 
ability to capture the impact of severe economic stress in financial 
markets. Alternative approaches to the global market shock could 
include employing instantaneous shock events across multiple as-of 
dates, rather than the current approach of selecting a single date for 
an instantaneous shock event. Another approach could involve an annual 
stress test that features multiple global market shock components on a 
single as-of date, which would allow the Board to compare a given 
firm's losses across a variety of types of shocks for a given set of 
trading position. The set of losses generated by such multiple market 
scenarios could be aggregated using a simple average, an average of the 
two worst outcomes, or another technique. These alternatives could 
enhance the dynamism of the annual stress tests and improve the Board's 
ability to evaluate the impact of severe economic stress on trading 
positions in a given annual stress test. However, these changes could 
also increase the complexity of the tests, and affect their 
predictability from year to year.
    Question 44: What changes could the Board implement to improve the 
general design of the global market shock? What, if any, alternative 
approaches should the Board consider? For instance, should the Board 
consider adjusting the global market shock so that shock events occur 
on multiple dates within the as-of date window? Should the Board 
consider testing more than one global market shock component in a given 
annual stress test or on a particular date? If so, how should the Board 
assess whether the current design, or alternative approaches, 
contribute to outcomes that are overly volatile or insufficiently 
representative of risks? If the Board should adopt these alternative 
approaches, what information should the Board provide to the public 
about how it will implement these alternatives, and should that 
information be published as part of a revised Scenario Design Policy 
Statement, codified as part of Regulation YY, the annual scenario 
disclosure, or some other means?
    Question 45: If the Board did adjust the global market shock to 
consider multiple dates within the as-of date window or more than one 
global market shock component in a given annual stress test or on a 
particular date, what method should the Board use to aggregate these 
values to calculate a firm's trading and counterparty losses in the 
stress test and why? For example, should the Board consider averaging 
the two instances of highest trading and counterparty losses? What 
would be the advantages and disadvantages of these aggregation methods?
    Question 46: The global market shock component and the largest 
counterparty default component of the severely adverse scenario are 
both based on the global market shock. Should the Board consider 
removing one or both of these components from the severely adverse 
scenario? If so, what alternative approaches should the Board consider 
to account for trading and counterparty losses in the supervisory 
stress test? For example, should trading and counterparty losses be 
considered as part of the macroeconomic scenario as opposed to the 
global market shock? What would be the advantages and disadvantages of 
retaining these components or replacing them with alternative 
approaches?
    Question 47: Should the Board continue to include a global market 
shock component in the severely adverse scenario? What would be the 
advantages and disadvantages of including a market shock component in 
the severely adverse scenario? If the Board determines to remove the 
market shock component, are there additional changes that the Board 
should implement that would mitigate any disadvantages from this 
change?
    Question 48: The global market shock component currently applies to 
firms subject to Category I, II, and III standards that have aggregate 
trading assets and liabilities of $50 billion or more, or trading 
assets and liabilities equal to or greater than 10 percent of total 
consolidated assets. What are the advantages and disadvantages of 
applying the global market shock component to this group of firms? 
Should this component apply to a different set or subset of firms? If 
so, how should the Board determine which set or subset of firms should 
be subject to the global market shock component?
Shock Values
    The Board generates shock values for all exposures in the global 
market shock template. Shock values represent the

[[Page 51928]]

magnitudes of changes to the financial risk factors and reflect the 
severity of market stress that these risk factors experience in the 
scenario. Table 24 provides an overview of the proposed shock 
definitions by asset class.

[[Page 51929]]


[GRAPHIC] [TIFF OMITTED] TP18NO25.070

Liquidity Horizons
    Financial risk factor shocks are calibrated based on assumed time 
horizons that reflect several scenario design considerations. The 
horizons are generally longer than the typical times needed to 
liquidate exposures under normal conditions because they are designed 
to capture the unpredictable liquidity conditions that prevail in times 
of stress. The Board is proposing to add descriptions of the liquidity 
horizons in the Scenario Design Policy Statement.
    As discussed below, the Board is proposing horizons that are 
intended to maintain consistency with the timeline for attributing 
losses stemming from these risk factors. Specifically, losses 
associated with the global market shock component are recognized in the 
first quarter of the projection horizon, which indicates that these 
shocks occur within a three-month period and thus implies a three-month 
upper bound for calibrating the shocks.
    The Board is proposing to amend its Scenario Design Policy 
Statement to use shock liquidity horizons that are broadly consistent 
with the proposed standards in the Basel Committee on Banking 
Supervision's Fundamental Review of the Trading Book (FRTB).\249\ The 
risk factors in the FRTB are similar to the ones in global market 
shock. The horizons in the FRTB were determined by the Basel Committee 
in consultations with the financial industry and represent the general 
consensus of a broad range of regulation authorities and the industry. 
Therefore, they are a reasonable benchmark for defining the shock 
horizons used in the global market shock. The Board departed from the 
FRTB slightly by specifying the same liquidity horizon to all risk 
factors in the same asset class. This choice was consistent with the 
Board's stress test principle of simplicity and facilitated a more 
straightforward modeling framework for the global market shock.
---------------------------------------------------------------------------

    \249\ Basel Committee on Banking Supervision, ``Calculation of 
RWA for market risk,'' in The Basel Framework 675-970, https://www.bis.org/baselframework/BaselFramework.pdf. See also 88 FR 64028, 
64138 (Sep. 18, 2023).
---------------------------------------------------------------------------

    The liquidity horizons used in the global market shock component 
are not perfectly matched with the FRTB liquidity horizons due to 
granularity differences between the FRTB standards and the global 
market shock template. The FRTB specifies horizons at a more granular 
level, often using different horizons within each asset class. For 
example, the FRTB specifies sovereign risk factor horizons by credit 
rating. In contrast, the global market shock template specifies 
sovereign shocks by country to capture country-specific risks not 
reflected by credit ratings. Moreover, the Board uses the same 
liquidity horizon for all risk factors within each asset class, whereas 
the FRTB allows for different horizons within asset classes. Given 
these differences, the global market shock scenario aims at aligning 
with the horizons specified by the FRTB by using a weighted average of 
the FRTB horizons within each asset class. The weights are determined 
using aggregate firm exposures over past submission quarters. For 
example, FRTB horizons for equity risk factors vary between 10 and 60 
business days, and the global market shock horizon for this asset class 
would be four weeks. Because the Board imposes an upper bound on global 
market shock horizons of one quarter, there are cases where the range 
of FRTB horizons would be longer than the global market shock horizon. 
For example, FRTB horizons for corporate credit risk factors vary 
between 60 and 120 business days, but the Board uses a horizon of three 
months for corporate credit. See Table 25.

[[Page 51930]]

    Question 49: What are the advantages and disadvantages of the 
Board's proposed liquidity horizons? What, if any, additional or 
alternative liquidity time horizons should the Board consider?
Global Market Shock Simplification
    As discussed in Section II.B of this Supplementary Information, the 
global market shock specifies hypothetical shocks to a standard set of 
risk factors. Currently, the global market shock discloses more than 
20,000 risk factors that reflect sudden market distress and heightened 
uncertainty. Statistical models are used to generate a subset of risk 
factors out of these 20,000 risk factors with the remaining ones 
generated by simple mapping. However, this latter category includes 
many risk factors that are often not material (for example, certain 
commodity shocks). These low-materiality exposures do not necessarily 
enhance the risk capture of the global market shock component.
    To address these issues and simplify the global market shock 
component, the Board is proposing to substantially reduce the number of 
disclosed risk factors. Specifically, this would reduce the number of 
disclosed risk factors to approximately 2,300 shocks, determined based 
on their relevance for developing a global market shock scenario 
narrative, the materiality of the risk factor, data quality, and 
consistency across asset classes.
    Under this approach, the Board would also review consistency across 
asset classes. In this regard, where possible, the Board would generate 
shocks to the same set of countries, regions, and tenor points across 
different asset classes. Such consistency would simplify shock 
comparison across different asset classes and improve public 
understanding of the global market shock component. Additionally, the 
Board is proposing to remove the inclusion of shocks to the values of 
private equity positions in section 3.2(b)(viii) of the Scenario Design 
Policy Statement, because private equity exposures are now stressed 
using the severely adverse macroeconomic scenario.
    Question 50: What are the advantages and disadvantages of 
simplifying the global market shock's specification of risk factor 
shocks? What are the advantages and disadvantages of removing shocks 
related to the value of private equity positions from the global market 
shock component?

X. Economic Analysis

Introduction

    In December 2024, the Board announced that it would seek public

[[Page 51931]]

comment on significant changes to improve the transparency of its 
supervisory stress test and to reduce the volatility of resulting 
capital buffer requirements.\250\ As discussed in Section II.E of this 
Supplementary Information, this proposal would improve the transparency 
and public accountability surrounding the stress test models and 
scenarios, as well as make certain changes to their underlying 
methodologies, which could provide meaningful benefits to the public as 
discussed below. This section provides economic analysis of the 
enhanced disclosure of the supervisory stress test framework.
---------------------------------------------------------------------------

    \250\ See Board, Press Release (Dec. 23, 2024), https://www.federalreserve.gov/newsevents/pressreleases/bcreg20241223a.htm. 
In February 2025, the Board stated that it would begin the public 
comment process on comprehensive changes to the supervisory stress 
test in 2025. See Board, Press Release (Feb. 5, 2025), https://www.federalreserve.gov/newsevents/pressreleases/bcreg20250205a.htm.
---------------------------------------------------------------------------

    The Board's supervisory stress test has historically operated with 
some disclosure regarding the stress test models and scenarios used, 
with an increase in public information provided beginning in 2019, as 
discussed in Section II.B of this Supplementary Information. The 
comprehensive model documentation that the Board is publishing on its 
website, as well as the proposed enhanced disclosure process for the 
models and scenarios, provides several benefits, including improved 
credibility of the stress test, improvement in feedback regarding the 
modeling process, better informed investors, and improved market 
discipline. However, the enhanced disclosure comes with costs as well, 
including reduced model dynamism, and increased systemic reliance on a 
single model, that is, ``model monoculture.''

Baseline

    The economic analysis uses the current stress testing framework, 
including the current disclosure regime, as the baseline. Throughout 
the analysis, the Board assesses the economic impact of the proposal by 
comparing outcomes under the proposal to the outcomes estimated under 
the baseline.

Proposed Policy Changes

    With this proposal, the Board is providing a comprehensive 
description of the modeling framework used to conduct the supervisory 
stress test: the equations, variables and parameters of each model used 
to estimate the projections that, when aggregated, produce the results 
of the supervisory stress test. This proposal would also codify an 
enhanced disclosure process under which the Board would annually 
publish the stress test models, invite public comment on any material 
changes to the models, and seek comment on the annual stress test 
scenarios. This represents a significant increase in disclosure 
relative to present, as current stress test disclosures are more 
limited, for example, current disclosures cover the structure of the 
stress testing model framework and key variables, along with 
hypothetical portfolio loss rates for select corporate and retail loss 
models.
    In addition, this proposal would change the stress test jump-off 
date and the GMS as-of date, as described in Sections VI.A and VI.B of 
this Supplementary Information. These changes would adjust the stress 
testing schedule to accommodate the public comment process and mitigate 
risks that the enhanced disclosure provided under this proposal would 
undermine the goals of supervisory stress testing.
    Section VIII.A of this Supplementary Information summarizes 
proposed changes to the stress testing models from the 2025 to the 2026 
supervisory stress test, which would inform the Board's determination 
of firms' stress capital buffer requirements.\251\ Section VIII.B 
provides an analysis of the potential effects of these proposed model 
changes.

    \251\ For a more detailed discussion of the proposed model 
changes, see https://www.federalreserve.gov/supervisionreg/dfa-stress-tests-2026.htm.
---------------------------------------------------------------------------

    Finally, Sections V and IX of this Supplementary Information 
describe proposed changes to the Board's Stress Testing Policy 
Statement and Scenario Design Policy Statement. The proposed changes to 
the Board's Stress Testing Policy Statement and Scenario Design Policy 
Statement are intended to express the Board's expectations for how the 
Board conducts the annual supervisory stress test and designs annual 
scenarios for the annual supervisory stress test. These changes provide 
additional transparency, public accountability, and predictability 
without creating binding legal obligations or economic impact.

Analysis of Benefits and Costs of Enhanced Model Disclosure

Benefits
a. Improved Credibility of the Stress Test
    The supervisory stress test has material safety and soundness 
benefits and these benefits are likely more sustainable when the 
Board's stress testing program operates with high levels of 
accountability and credibility. Disclosing comprehensive model 
documentation to the public ensures that all institutions and 
stakeholders have equal access to the supervisory methodology, which 
could improve accountability in supervisory decision-making, promote 
fairness, and reinforce trust in the stress testing process. Publicly 
disclosing the stress test models and scenarios also enhances trust in 
the stress testing process,\252\ as stakeholders may be able to better 
assess the soundness of models and their alignment with best 
practices.\253\ As a result, firms may understand better where there 
are discrepancies between their own internal stress testing models and 
the supervisory stress testing models, and consequently they may be 
better positioned to communicate specific concerns with supervisors. 
With greater transparency and public accountability, stakeholders may 
be more confident that the supervisory stress test results do not 
reflect the desires of firms or supervisors to obtain a specific 
outcome.\254\ While the Board has previously released enhanced 
disclosures of the stress test models, such as portfolio-level average 
loss rates, macro-to-loss linkages, and risk drivers, the comprehensive 
model documentation disclosed in connection with this proposal better 
illustrates how supervisors incorporate model refinements and emerging 
risks, which could further improve credibility over time.
---------------------------------------------------------------------------

transparency, which generally suggest a mixed-to-positive impact on 
trust, see M. Cucciniello et al., 25 Years of Transparency Research: 
Evidence and Future Directions, 77 Public Admin. Rev. 32-44 (2016).
    \253\ See I. Goldstein & Y. Leitner, ``Stress test disclosure: 
theory, practice, and new perspectives,'' Handbook of Financial 
Stress Testing 208-223 (2022).

Results Be Disclosed? An Analysis of the Costs and Benefits, 8 
Foundations and Trends in Finance 1-54 (2013); F. Niepmann & V. 
Stebunovs, Modeling our stress away, 158 Journal of Banking & 
Finance 107042 (2024). When regulators are more constrained in their 
ability to make the models more or less severe, this could alleviate 
inefficient strategic interactions between supervisors and banks, 
referred to as ``policy traps.'' J. Shapiro & J. Zeng, Stress 
Testing and Bank Lending, 37 Rev. of Fin. Studies 1265-1314 (2024).
---------------------------------------------------------------------------

    In addition, as described in Section VI.B of this Supplementary 
Information, this proposal would extend the date selection range of GMS 
as-of date from five months (between October 1 of the previous year and 
March 1 of a given year) to a full year (between October 1 of two years 
prior to a given stress test cycle to October 1 of the year prior to a 
given stress test cycle). Thus, the GMS

[[Page 51932]]

could be applied to market risk positions held by the firms on any 
selected date within the full year instead of the current five months. 
This change could reduce firm's risk gaming activities such as ``window 
dressing'' for firms subject to the GMS. Therefore, the resulting 
improved risk capture would further enhance the credibility of the 
stress test results.
b. Improved Model Feedback
    The Board's supervisory stress test models consist of equations, 
parameters, and assumptions that translate hypothetical macroeconomic 
shocks under designed stress scenarios into loss estimates across asset 
classes, income streams, and capital ratios. Despite their complexity, 
the supervisory stress test models and stress scenarios, like all 
theoretical models, remain simplified representations of reality. As 
such, they benefit from feedback and refinement. Public disclosure of 
models and scenarios should provide academics, industry professionals, 
and the broader risk community with the information to provide more 
effective feedback.\255\ For example, in past supervisory stress 
testing cycles, stakeholders have raised concerns about loss rates on 
certain asset classes. Over time, such feedback could help to refine 
and improve the models and scenarios as they could be updated to 
mitigate concerns, as appropriate. In this sense, the proposal's 
enhanced disclosure could facilitate stakeholders' feedback, ultimately 
leading to better modelling performance and further enhancing the 
credibility of the supervisory stress testing process.\256\

---------------------------------------------------------------------------

c. Improved Ability To Evaluate Business Plans
    Comprehensive disclosure of the stress test models also may help 
firms better understand how supervisors assess losses under severely 
stressed hypothetical scenarios. This may allow firms to more 
accurately predict their required capital ratios, reducing capital 
planning uncertainty \257\ and possibly increasing firms' willingness 
to lend.\258\ Reduced capital requirement uncertainty could help firms 
better plan their future business decisions.

lending, see S. Gissler et al., Lending on hold: regulatory 
uncertainty and bank lending standards, 81 J. of Monetary Econ. 89-
101 (2016).
---------------------------------------------------------------------------

d. Better Informed Investors and Improved Market Discipline
    Research suggests that investors use stress test results to assess 
firms' resilience. Indeed, disclosures of results from the stress test 
tend to affect firms' stock prices and CDS spreads.\259\ Through such 
financial market signals, investors may help discipline firms' risk 
taking.\260\ This ``market discipline'' may constrain risk taking and 
incentivize firms to strengthen capital positions.\261\ The 
comprehensive disclosure of the supervisory stress testing models may 
allow investors to make better informed decisions, potentially 
improving the effectiveness of market discipline.

---------------------------------------------------------------------------

Costs

a. Reduced Dynamism
    As discussed above, models are necessarily a simplified version of 
reality. As forecasting methodologies evolve or conditions in the 
economy and the financial system change, the existing models may no 
longer adequately capture risks. For this reason, an effective stress 
test must be able to adapt. Under this proposal, material changes to 
the stress testing models would be published for comment, and the Board 
would be required to respond to such comment, before implementing the 
material model changes in the supervisory stress test. This process 
would increase the resources needed to develop, propose, and implement 
material model changes, particularly to the extent that any changes are 
complex, present many alternatives, or affect firms' ability to 
distribute capital. As a result, the use of new models or model changes 
that explore risks that are less established may pose a high resource 
burden under the proposed enhanced disclosure regime, potentially 
limiting the supervisory stress test to simpler, less controversial, 
and more familiar approaches.\262\ Tests of new risk dimensions or 
emerging threats may take significantly more time to implement. With 
less dynamism, the supervisory stress test may fail to capture new 
risks and could produce an increasingly stale view of how firms would 
be likely to perform under stressed conditions.\263\ In addition, as 
described in Section VI.A of this Supplementary Information, this 
proposal would change the jump-off date of the supervisory and company-
run stress tests from December 31 to September 30, to allow the Board 
to publish the annually disclosed stress test information for comment 
after the jump-off date of the stress test and to prevent firms from 
adjusting their exposures based on the published information. As a 
result, the tested balance sheets would be older by one quarter, which 
would add additional staleness to the stress test and stress test 
results, because firm balance sheets as well as economic conditions 
could change substantially within a quarter.
---------------------------------------------------------------------------

    \262\ See M. Flannery, Transparency and model evolution in 
stress testing, SSRN Working Paper (2019), http://dx.doi.org/10.2139/ssrn.3431679. Even the current approach to stress testing 
may not allow for the optimal level of dynamism or macroprudential 
considerations. See D. Tarullo, Reconsidering the regulatory uses of 
stress testing, Hutchins Center Working Paper 92 (2024), https://www.brookings.edu/wp-content/uploads/2024/05/WP92_Tarullo-stress-testing.pdf; W. Bassett & D. Rappoport, ``Enhancing stress tests by 
adding macroprudential elements,'' in Handbook of Financial Stress 
Testing 455-83 (2022).

model, see W. Frame et al., The failure of supervisory stress 
testing: Fannie Mae, Freddie Mac, and OFHEO, Federal Reserve Bank of 
Boston Working Paper 15-4 (2015), https://www.bostonfed.org/-/media/Documents/Workingpapers/PDF/wp1504.pdf.
---------------------------------------------------------------------------

b. Reduced Risk Sensitivity and Overreliance on a Single Model 
Framework
    Supervisory stress testing results are important inputs to the 
capital requirements associated with firms'

[[Page 51933]]

banking activities. With comprehensive model disclosure likely reducing 
the uncertainty of supervisory stress test results, firms' estimates of 
future regulatory capital requirements could rely more on the Board's 
stress test models and less on their own internal stress testing models 
or internal risk management tools, both of which may be less useful 
than before for managing regulatory capital.\264\ To the extent that 
firms' own internal stress testing models or risk management tools 
provide additional information about risk, the expected capital 
requirements could become less risk-sensitive as a result and it may 
reduce firms' incentives to independently measure and manage their 
vulnerabilities.
---------------------------------------------------------------------------

    \264\ T. Schuermann, ``The Fed's Stress Tests Add Risk to the 
Financial System,'' W.S.J. (Mar. 19, 2013), https://www.wsj.com/articles/SB10001424127887324532004578362543899602754?gaa_at=eafs&gaa_n=ASWzDAgXgiqB0fwSIwZXAJZF5iLfwSHPFItS1v9pIwVWyP1FFRG2TyjbJ153&gaa_ts=68e66a22&gaa_sig=QXBddH1PbBwcemmdRad58NRIsIlftxSu-CxAv7UOygRlCujSJqcMQF1rlakd0GGI4045knXKHn-H06BNwTBP-Q%3D%3D.
---------------------------------------------------------------------------

    Disclosure could also enable firms to more easily optimize their 
exposures to minimize capital requirements in the supervisory stress 
test, which could allow vulnerabilities to build up where risks are not 
well or fully accounted for by standardized supervisory models.
    Reliance on the supervisory stress testing models could extend 
further if disclosure results in firms increasing the similarity of 
their own stress models to the stress test models.\265\ Increased 
reliance of all stress tested firms on a single model, known as ``model 
monoculture,'' or delaying material model changes while risks build up 
in areas that are treated benignly in the stress test would pose risks, 
as firms may face a greater incentive to shift business activities 
towards these areas to reduce their capital requirements.\266\ The 
resulting convergence of risk taking could increase the vulnerability 
of the banking system, particularly to those risks that are under-
reflected by the supervisory stress testing models.\267\
---------------------------------------------------------------------------

    \265\ Of course, as noted above, there is benefit to these 
changes to the extent that they are adopted to improve the ability 
of firms' models to capture risk.
    \266\ Relatedly, banks may have a stronger incentive to 
temporarily curtail those risk exposures treated adversely by the 
stress testing models, i.e., to ``window dress.'' See P. Alexander,

Conclusion

    As discussed in the introduction to Section X.D of this 
Supplementary Information, the Board's supervisory stress test has 
historically operated with partial disclosure regarding the stress test 
models used. The comprehensive model documentation published in 
connection with this proposal, as well as the proposed enhanced 
disclosure process, provides several benefits that outweigh the costs 
of the proposal.
    Taken together, the Board assessed that the benefits of the 
proposal justify the costs.
    Question 51: What, if any, additional material costs or benefits 
should the Board consider, in addition to those discussed in the 
proposal?
    Question 52: What alternatives that achieve the objectives of the 
proposal should the Board evaluate? Please provide specific suggestions 
and rationales for any proposed alternatives, including how they might 
address potential unintended consequences or better achieve the 
proposal's goals.

XI. Administrative Law Matters

A. Paperwork Reduction Act Analysis

    In accordance with the requirements of the Paperwork Reduction Act 
(PRA) of 1995 (44 U.S.C. 3501-3521), the Board may not conduct or 
sponsor, and the respondent is not required to respond to, an 
information collection unless it displays a currently valid Office of 
Management and Budget (OMB) control number. The Board reviewed the 
information collections related to the proposed rule under the 
authority delegated to the Board by OMB.
    The proposed rule would not create any information collections 
subject to the PRA; however, the Board is proposing to revise the FR Y-
14A/Q/M to reduce regulatory reporting burden by retiring items and 
removing supporting documentation requirements that are no longer 
needed to conduct the supervisory stress test. Additionally, the Board 
is proposing to collect additional information to support the proposed 
supervisory stress test models.
    The Board invites public comment on the following information 
collection:
    (a) Whether the collection of information is necessary for the 
proper performance of the Board's functions, including whether the 
information has practical utility;
    (b) The accuracy of the Board's estimate of the burden of the 
proposed information collection, including the validity of the 
methodology and assumptions used;
    (c) Ways to enhance the quality, utility, and clarity of the 
information to be collected;
    (d) Ways to minimize the burden of the information collection on 
respondents, including through the use of automated collection 
techniques or other forms of information technology; and
    (e) Estimates of capital or start-up costs and costs of operation, 
maintenance, and purchase of services to provide information.
Proposal Under OMB Delegated Authority To Extend for Three Years, With 
Revision, the Following Information Collection
    Collection title: Capital Assessments and Stress Testing Reports.
    Collection identifier: FR Y-14A/Q/M.
    OMB control number: 7100-0341.
    General description of collection: This family of information 
collections is composed of the following three reports:
     The annual FR Y-14A collects quantitative projections of 
balance sheet, income, losses, and capital across a range of 
macroeconomic scenarios and qualitative information on methodologies 
used to develop internal projections of capital across scenarios.\268\
---------------------------------------------------------------------------

    \268\ In certain circumstances, a firm may be required to re-
submit its capital plan. See 12 CFR 225.8(e)(4); 12 CFR 
238.170(e)(4). Firms that must re-submit their capital plan 
generally also must provide a revised FR Y-14A in connection with 
their resubmission.
---------------------------------------------------------------------------

     The quarterly FR Y-14Q collects granular data on various 
asset classes, including loans, securities, trading assets, and pre-
provision net revenue for the reporting period.
     The monthly FR Y-14M is comprised of three retail 
portfolio- and loan-level schedules, and one detailed address-matching 
schedule to supplement two of the portfolio- and loan-level schedules.

[[Page 51934]]

    The data collected through the FR Y-14A/Q/M provide the Board with 
the information needed to help ensure that large firms have strong, 
firm-wide risk measurement and management processes supporting their 
internal assessments of capital adequacy and that their capital 
resources are sufficient, given their business focus, activities, and 
resulting risk exposures. The data within the reports are used in 
connection with setting firms' stress capital buffer requirements. The 
data are also used to support other Board supervisory efforts aimed at 
enhancing the continued viability of large firms, including continuous 
monitoring of firms' planning and management of liquidity and funding 
resources, as well as regular assessments of credit risk, market risk, 
and operational risk, and associated risk management practices. 
Information gathered in this collection is also used in the supervision 
and regulation of respondent financial institutions. Respondent firms 
are currently required to complete and submit up to 17 filings each 
year: one annual FR Y-14A filing, four quarterly FR Y-14Q filings, and 
12 monthly FR Y-14M filings.\269\ Compliance with the information 
collection is mandatory.
---------------------------------------------------------------------------

    \269\ Holding companies that do not meet the materiality 
thresholds described in the instructions for the FR Y-14M are not 
required to file that report. This results in some holding companies 
submitting fewer than 17 filings each year.
---------------------------------------------------------------------------

    Current Actions: The proposal would modify the FR Y-14A/Q/M to 
remove supporting documentation requirements, schedules, and data items 
that are no longer needed to conduct the supervisory stress test. The 
proposal would also make other revisions necessary to facilitate the 
stress test modeling decisions. All proposed revisions would be 
effective for the September 30, 2026, report date.
Supporting Documentation
a. FR Y-14A
    The FR Y-14A collects detailed data on firms' quantitative 
projections of assets, liabilities, income, losses, and capital across 
a range of macroeconomic scenarios. Firms are also required to provide 
qualitative information on the methodologies used to develop their 
projections and any other analysis that supports or contributes to 
these projections. This qualitative supporting documentation helps 
supervisors assess the accuracy and comprehensiveness of the 
projections included in firms' FR Y-14A submissions. This information 
was previously critical to assess the data systems and modeling 
methodologies that firms used to report the FR Y-14A. However, as these 
systems and frameworks have matured, much of the supporting 
documentation has become outdated or is not needed by supervisors to 
make such assessments. To ensure that the FR Y-14A requirements do not 
capture information that is no longer needed and to reduce reporting 
burden, the Board is proposing to remove Appendix A ``Supporting 
Documentation'' from the FR Y-14A. However, supervisors may request 
similar information to what is currently required from Appendix A from 
firms through supervisory channels, as deemed appropriate and on a 
targeted basis, in support of the annual capital plan review. Firms 
would only be expected to provide information that supervisors request 
each cycle. The proposed removal of the FR Y-14A supporting 
documentation reporting requirement would not impact any other capital 
planning expectations.
b. FR Y-14Q
    FR Y-14Q, Schedule L (Counterparty) collects data on firms' 
counterparty credit risk, including derivative and securities financing 
transaction exposures. Applicable firms are required to report two 
versions of Schedule L: an ``unstressed'' version under the actual 
economic conditions on the reported date, and a ``stressed'' version 
under the hypothetical stress scenarios used in the supervisory and 
company-run stress tests. To support firms' estimates of credit 
valuation adjustment and counterparty losses under the stress 
scenarios, the FR Y-14Q requires that firms provide detailed 
descriptions of the methodologies used to generate values for the 
``stressed'' version. As for the FR Y-14A, this information was 
previously important in understanding firms' counterparty submissions 
but is no longer required for supervisors to assess Schedule L data. 
However, the Board has identified supporting information that is 
relevant to understanding a firm's estimated credit valuation 
adjustment and largest counterparty default losses. Therefore, to 
streamline Schedule L and reduce reporting burden, the Board is 
proposing replacing the existing Schedule L supporting documentation 
with this more limited set of questions. These questions would concern 
excluded counterparties, estimation assumptions, drivers of changes in 
credit valuation adjustment, and other related topics.
    Similarly, qualitative information is needed to assess firms' 
trading mark-to-market projections under the global market shock. As a 
firm's projections are directly connected to the exposures reported on 
FR Y-14Q, Schedule F (Trading), the Board is proposing to introduce 
supporting documentation for Schedule F that includes five questions 
related to a firm's trading projections and Schedule F submissions. 
Together with the Schedule L supporting documentation, this would 
ensure that supervisors have the necessary information to assess a 
firm's projections under the global market shock.
Home Equity Data Collection
    FR Y-14M, Schedule B.1 (Home Equity Loan-Level Table) collects 
loan-level data on firms' HELOCs. These data are used in support of 
stress test modeling and monitoring of firms' home equity portfolios. 
The Board has identified several items on Schedule B.1 that are not 
needed to assess a home equity loan or HELOC's risk characteristics or 
are captured elsewhere on Schedule B.1. Therefore, to maintain 
appropriate risk coverage and reduce reporting burden, the Board is 
proposing to retire the following fields from Schedule B.1.

 Item 18 (Number of Units)
 Item 31 (ARM Periodic Rate Cap)
 Item 32 (ARM Periodic Rate Floor)
 Item 38 (Bankruptcy Flag)
 Item 48 (Foreclosure Referral Date)
 Item 51 (Pre-Payment Penalty Term)
 Item 58 (Interest Rate Frozen)
 Item 59 (Principal Deferred)
 Item 62 (First Mortgage Serviced in House)
 Item 72 (Term Modification)
 Item 73 (Principal Write-Down)
 Item 74 (Line Re-Age)
 Item 75 (Loan Extension)
 Item 86 (Accrual Status)
 Item 87 (Foreclosure Suspended)
 Item 88 (Property Valuation Method at Origination)
 Item 92 (Third Party Sale Flag)
 Item 107 (Entity Type)
Collection of Mailing Address Information
    FR Y-14M, Schedule C (Address Matching) collects address 
information on each loan reported on FR Y-14M, Schedule A (First Lien) 
or Schedule B (Home Equity). This collection includes both property and 
mailing address data used in support of the supervisory stress test 
models. However, the Board has determined that the mailing address 
items are no longer needed for stress testing or supervisory purposes. 
Therefore, the Board is proposing to remove item 6 (Mailing Stress 
Address), item 7 (Mailing City), item 8 (Mailing State), and item 9 
(Mailing Zip Code) from Schedule C.

[[Page 51935]]

Unpaid Principal Balance
    FR Y-14M, Schedule B.1 item 95 (Unpaid Principal Balance (Net)) 
collects information on the current net unpaid principal balance of a 
home equity line of credit. The instructions provide a definition for 
calculating net unpaid principal balance and note that this value 
should equal the book value on regulatory filings. However, reporting 
of unpaid principal balance can vary across regulatory reporting, 
including by considering loan premiums, which item 95 does not include. 
To address this inconsistency, the Board is proposing to remove this 
language from the instructions for item 95.
Private Equity
    Beginning with the 2025 supervisory stress test, the Board 
calculated losses on private equity exposures under the macroeconomic 
scenario over a nine-quarter projection horizon as opposed to under the 
GMS, which would have considered the impact only in the first quarter 
of the projection horizon. As described in the Board's 2025 Supervisory 
Stress Test Methodology disclosure,\270\ the new treatment better 
aligns with the characteristics of private equity exposures, which are 
principally long-term investments that are managed as banking book 
positions. To better capture private equity data in a manner that 
aligns with this new treatment, the Board is proposing several 
revisions to FR Y-14Q, Schedule F (Trading).
---------------------------------------------------------------------------

    \270\ See Board, 2025 Stress Test Scenarios (Feb. 2025), https://www.federalreserve.gov/publications/files/2025-stress-test-scenarios-20250205.pdf.
---------------------------------------------------------------------------

    First, the Board is proposing to move the fourth quarter as-of date 
for reported private equity exposures to December 31 of a given year, 
as opposed to the as-of date of the GMS. Schedule F is reported on a 
quarterly basis. However, to gather data necessary to subject firms to 
the GMS, firms are required to report Schedule F as of the GMS as-of 
date and not as of December 31 for the fourth quarter submission. 
Therefore, the Board is proposing to require private equity exposures 
to be reported as of December 31, as private equity exposures are no 
longer stressed under the GMS.
    Second, the Board is proposing to revise Schedule F such that 
private equity carry values are reported net of embedded goodwill or 
investments in the capital of unconsolidated financial institutions 
that are deducted from common equity tier 1 capital. The Board's 
capital rule provides that certain amounts of goodwill and investments 
in the capital of unconsolidated financial institutions be deducted 
from CET1 capital,\271\ and the carry value of private equity exposures 
reported on Schedule F can be affected by these deducted amounts.
---------------------------------------------------------------------------

    \271\ See 12 CFR 217.22.
---------------------------------------------------------------------------

    Firms subject to Category I through III standards are required to 
report these deduction items on FR Y-14A, Schedule A.1.d (Capital). To 
ensure that deductions are not double-counted when calculating trading 
and counterparty losses, firms may report an adjusted starting value 
for these items to reflect the impact of the global market shock. 
However, as currently reported, a portion of these amounts may be 
attributable to private equity. Therefore, the Board is proposing 
revising Schedule F to require firms to exclude the amounts 
attributable to private equity from the carry value. This revision 
would ensure that losses are not assigned to balances that have been 
deducted from capital when calculating private equity losses.
    Third, the Board is proposing to require hedges on private equity 
exposures to be separately reported on Schedule F. Hedges on private 
equity exposures are currently reported on Schedule F but are not 
segmented from other hedges on trading exposures. Given that private 
equity exposures are no longer stressed as part of the GMS, the Board 
is proposing to require hedges on private equity exposures to be 
reported separately so that they can be considered as part of the 
macroeconomic scenario.
    Lastly, the Board is proposing to implement a new materiality 
threshold for the reporting of Schedule F.24 (Private Equity). 
Currently, Schedule F.24 is reported only by firms subject to Category 
I through III standards with substantial trading operations, which is 
defined as having, on average for four quarters, aggregate trading 
assets and liabilities of $50 billion or more, or aggregate trading 
assets and liabilities equal to 10 percent or more of total 
consolidated assets. However, private equity exposures are primarily 
banking book positions for which the FR Y-14 uses a separate reporting 
threshold. For firms subject to Category IV standards, material 
portfolios for banking book positions are defined as those with asset 
balances greater than $5 billion or with asset balances greater than 
ten percent of tier 1 capital on average for the four quarters 
preceding the reporting period. For firms subject to Category I through 
III standards, material portfolios for banking book positions are 
defined as those with asset balances greater than $5 billion or asset 
balances greater than five percent of tier 1 capital on average for the 
four quarters preceding the reporting period.
    To align the materiality threshold for private equity with other 
banking book schedules, the Board is proposing to revise the FR Y-14Q 
instructions to apply the materiality threshold to Schedule F.24 that 
is currently applied to the banking book schedules. Additionally, since 
a firm subject to Category IV standards could have its private equity 
losses contribute to its supervisory stress test results, the Board 
also proposes to require a firm subject to Category IV standards to 
submit Schedule F.24 if it meets the proposed materiality threshold. 
Similarly, consistent with reporting expectations for other banking 
book positions, the Board is proposing to update FR Y-14Q, Schedule K 
(Supplemental) such that firms report the carrying value of funded and 
unfunded private equity exposures that do not meet the materiality 
threshold for Schedule F.24 reporting. These revisions would ensure 
consistent reporting and treatment of private equity in the supervisory 
stress test.
    Additionally, the Board is proposing a revision to FR Y-14A, 
Schedule A.4 (Trading) which captures trading profit and loss 
projections under the global market shock. As private equity shocks are 
no longer included in the global market shock, items related to private 
equity are no longer needed to capture trading profit and loss 
projections. Therefore, the Board is proposing to remove item 15 
(``Private Equity''), item 15A (``Private Equity: Funded''), item 15B 
(``Private Equity: Unfunded''), item 15C (``Private Equity: Other'') 
from Schedule A.4.
Other Hedges
    Currently, the FR Y-14Q captures certain types of hedges, including 
hedges on accrual loans and loans held under the fair value option and 
certain designated accounting hedges on securities, but is not 
comprehensive, which limits the ability of the supervisory stress test 
to account for these positions. For example, FR Y-14Q, Schedule B 
(Securities) does not provide sufficient information to independently 
revalue the hedging instrument. Additionally, interest rate risk hedges 
that are used to mitigate risk on instruments other than securities 
from changes in interest rates are not captured by the FR Y-14Q. 
Schedule B was designed to capture basic information on traditional 
hedges on securities and does not consistently and comprehensively 
capture portfolio layer

[[Page 51936]]

method or interest rate risk hedges for valuation purposes.
    Separately, fair value option hedges are positions that are used to 
hedge loan assets that are held-for-sale or held under fair value 
option accounting, and do not meet the definition of trading assets or 
liabilities. This includes synthetic securitizations, a form of loss 
mitigation in which a firm partially transfers credit risk on specific 
portfolios to outside investors through credit derivatives or 
guarantees. Fair value option hedges are currently reported as a 
separate instance of Schedule F. However, Schedule F is subject to a 
materiality threshold, so fair value option hedges are not reported 
comprehensively by all relevant firms on the FR Y-14Q.
    To improve the risk capture of the supervisory stress test by 
incorporating the effects of additional hedges, the Board is proposing 
to revise FR Y-14Q, Schedule B.2 (Investment Securities with Designated 
Accounting Hedges) to capture all qualified accounting hedges, 
including portfolio layer method and all designated accounting hedges. 
Additionally, the Board is proposing to implement FR Y-14Q, Schedule 
B.3 to more comprehensively map hedging relationships. Similarly, the 
Board is proposing to revise Schedule F to capture data on hedges from 
any firms with reportable hedges.
    Question 53: Would the new fields proposed in FR Y-14Q, Schedule 
B.2 or B.3 prove burdensome to report for firms?
    Question 54: Do the new fields proposed in FR Y-14Q, Schedule B.2 
provide sufficient information to independently model the value of the 
hedging instrument?
    Question 55: Should changes be made to the fields or definitions 
proposed in FR Y-14Q, Schedule B.2 to better account for more esoteric 
derivatives such as swaptions, cap, or floors?
Exchange Traded Funds
    Exchange traded funds (ETFs) are investment funds comprised of 
exposures to multiple underlying assets, such as commodities, equities, 
or currencies. Currently, Schedule F instructs firms to decompose 
certain ETF exposures based on the fund's underlying assets. However, 
the instructions also provide that all other ETFs should be reported in 
the equity worksheets. This ambiguity may lead to classifying non-
equity ETFs in the equity worksheets.
    All ETFs should be reported based on the underlying asset holdings 
and associated risk factors. For example, ETFs for which rates or 
credit exposures are the underlying holdings should be reported on the 
corresponding worksheet. To provide clarity and ensure consistent 
reporting, the Board is proposing to clarify the Schedule F 
instructions such that all ETFs are reported in the worksheet that 
corresponds to the underlying asset class and risk exposures.
Credit Card Revenue and Loss Share Agreements
    Revenue and loss sharing agreements (RLSAs) are partnership 
agreements firms have with private entities to share a portion of 
profits, revenues, and/or losses generated by a specified asset. As 
discussed in the Credit Cards Model description, the Board accounts for 
private RLSAs when projecting credit card losses in the supervisory 
stress test. Currently, the Board's adjustment accounts for a specific 
case where a firm accounts for loss sharing payments by reducing 
provisions. However, as agreement terms and reporting practices vary, 
the current adjustment may not fully or consistently address 
differential RLSA treatment across firms. Therefore, the Board is 
considering additional enhancements to the current RLSA adjustment to 
more comprehensively capture RLSAs in the supervisory stress test. 
Specifically, the Board is considering one modeling approach that would 
account for RLSAs at the portfolio level and a second that would 
account for RLSAs at the agreement level. To facilitate the portfolio 
level enhancement, the Board is proposing to collect portfolio level 
details on FR Y-14M, Schedule D (Credit Card) of individual revenue 
components (e.g., interest income, interest expense, noninterest 
income, and noninterest expense), charge-offs and recoveries, and 
provision build. Additionally, the amount of each that is subject to 
partner sharing agreements and where the partner shares portions of 
each are reported on the FR Y-9C, as well as the shared amounts of net 
profit, net revenue, and net charge offs. To facilitate the agreement 
level enhancement, the Board is proposing to collect the same 
information at the agreement level, as well as effective share rates 
and contractual share rates of the individual revenue, loss, and 
provision components. For both approaches, the Board is proposing to 
expand Schedule D.1, item 70 (``Loss Sharing'') to collect information 
on the type of RLSA. If either the portfolio level or agreement level 
enhancement is adopted, the Board would only adopt the corresponding FR 
Y-14 revisions. If the Board does not adopt either enhancement to the 
RLSA adjustment, then neither set of revisions would be implemented. If 
either RLSA modeling enhancement is adopted, the corresponding FR Y-14 
revision would represent an increase in estimated FR Y-14 burden hours 
of approximately 2,500 hours if adopted.
Stress Test Date Changes
a. FR Y-14A Jump-Off Date
    The FR Y-14A collects data on firms' projections of balance sheet 
asset and liabilities, income, losses, and capital across a range of 
hypothetical scenarios. These projections span a nine-quarter horizon 
beginning with the first quarter of the year in which the report is 
filed. This means that the jump-off date for the FR Y-14A is December 
31 of the previous year, consistent with the supervisory stress test. 
However, as discussed in Section VI.A of this Supplementary 
Information, the Board is proposing to shift the jump-off date of the 
stress test to September 30 so that the scenarios are released for 
comment after the finalization of firms' balance sheets.
    Consistent with this proposed jump-off date change, the Board is 
proposing to modify the FR Y-14A to use a September 30 jump-off date. 
These revisions would include updating the instructions to note that 
the projection horizon begins in the fourth quarter of the year 
preceding the reporting year, and noting that firms should report 
actual capital actions in the first and second quarters of the 
projection horizon, as they occur before the due date. The FR Y-14A and 
capital plans would still be due April 5.
b. Global Market Shock as-of Date Submissions
    As discussed in Section VI.B of this Supplementary Information, the 
Board is proposing to expand the as-of date range for the global market 
shock to be between October 1 of two years prior to a given stress test 
cycle to October 1 of the year prior to a given stress test cycle. To 
facilitate this proposed change, the Board is proposing several changes 
to the FR Y-14A and FR Y-14Q.
    On the FR Y-14A, the Board is proposing to update Schedule A.4 
(Trading) and Schedule A.5 (Counterparty) such that the as-of date for 
these schedules may fall between October 1 of two years prior to a 
given stress test cycle to October 1 of the year prior to a given 
stress test cycle. These schedules would still be due on April 5 of the 
following year.

[[Page 51937]]

    Currently, the fourth quarter submissions of FR Y-14Q, Schedule F 
(Trading) and Schedule L (Counterparty) are submitted as of the global 
market shock as-of date instead of quarter end. However, under the 
proposal, the as-of date for the global market shock could fall in a 
quarter other than the fourth quarter. Therefore, Board is proposing to 
modify the submission cadence for Schedule F (Trading) and Schedule L 
(Counterparty) such that, for whichever quarter contains the global 
market shock as-of date, Schedule F and Schedule L would be submitted 
as of that date, as opposed to quarter end. Submissions for all other 
quarters would be submitted as-of quarter end.
    Question 56: What, if any, other FR Y-14 revisions are needed to 
facilitate the proposed changes to the stress test jump-off date and 
global market shock as-of date?
    Frequency: Annually, quarterly, and monthly.
    Respondents: Holding companies with $100 billion or more in total 
consolidated assets, as based on (1) the average of the firm's total 
consolidated assets in the four most recent quarters as reported 
quarterly on the firm's Consolidated Financial Statements for Holding 
Companies (FR Y-9C; OMB No. 7100-0128) or (2) the average of the firm's 
total consolidated assets in the most recent consecutive quarters as 
reported quarterly on the firm's FR Y-9Cs, if the firm has not filed an 
FR Y-9C for each of the most recent four quarters.
    Total estimated number of respondents: 35.
    Estimated change in burden:
     FR Y-14A: -4,235 hours.
     FR Y-14Q: -700 hours.
     FR Y-14M: +792 hours.
     Total estimated change in burden: -4,143.
    Total estimated annual burden hours: 757,696.

B. Regulatory Flexibility Act Analysis

    The Board is providing an initial regulatory flexibility analysis 
with respect to this proposed rule. The Regulatory Flexibility Act 
(RFA) \272\ requires an agency to consider whether the rules it 
proposes will have a significant economic impact on a substantial 
number of small entities.\273\ In connection with a proposed rule, the 
RFA requires an agency to prepare and invite public comment on an 
initial regulatory flexibility analysis describing the impact of the 
rule on small entities, unless the agency certifies that the proposed 
rule, if promulgated, will not have a significant economic impact on a 
substantial number of small entities. An initial regulatory flexibility 
analysis must contain (1) a description of the reasons why action by 
the agency is being considered; (2) a succinct statement of the 
objectives of, and legal basis for, the proposed rule; (3) a 
description of, and, where feasible, an estimate of the number of small 
entities to which the proposed rule will apply; (4) a description of 
the projected reporting, recordkeeping, and other compliance 
requirements of the proposed rule, including an estimate of the classes 
of small entities that will be subject to the requirement and the type 
of professional skills necessary for preparation of the report or 
record; (5) an identification, to the extent practicable, of all 
relevant Federal rules which may duplicate, overlap with, or conflict 
with the proposed rule; and (6) a description of any significant 
alternatives to the proposed rule which accomplish the stated 
objectives of applicable statutes and minimize any significant economic 
impact of the proposed rule on small entities.
---------------------------------------------------------------------------

    \272\ 5 U.S.C. 601 et seq.
    \273\ Under regulations issued by the U.S. Small Business 
Administration (SBA), a small entity includes a depository 
institution, bank holding company, or savings and loan holding 
company with total assets of $850 million or less. 13 CFR 121.201. 
Consistent with the SBA's General Principles of Affiliation, the 
Board includes the assets of all domestic and foreign affiliates 
toward the applicable size threshold when determining whether to 
classify a particular entity as a small entity. 13 CFR 121.103. As 
of December 31, 2024, there were approximately 2,364 small bank 
holding companies, approximately 85 small savings and loan holding 
companies, and approximately 451 small state member banks.
---------------------------------------------------------------------------

    The Board has considered the potential impact of the proposed rule 
on small entities in accordance with the RFA. Based on its analysis and 
for the reasons stated below, the Board believes that this proposed 
rule will not have a significant economic impact on a substantial 
number of small entities. Nevertheless, the Board is publishing and 
inviting comment on this initial regulatory flexibility analysis. In 
connection with this proposal, the Board also proposes to make changes 
to the Board's reporting forms.
    As discussed in detail above, under the proposal, the Board is 
inviting public comment on the models used to conduct the Board's 
supervisory stress test, changes to those models to be implemented in 
the 2026 stress test, and proposed changes to enhance the transparency 
and public accountability of the Board's stress testing framework. The 
proposal would amend the Policy Statement on the Scenario Design 
Framework for Stress Testing, including to implement guides for 
additional scenario variables, and the Stress Testing Policy Statement. 
The proposal would also codify an enhanced disclosure process under 
which the Board would annually publish comprehensive documentation on 
the stress test models, invite public comment on any material changes 
that the Board seeks to make to those models, and annually publish the 
stress test scenarios for comment. Lastly, the proposal would make 
changes to the FR Y-14A/Q/M to remove items that are no longer needed 
to conduct the supervisory stress test and to collect additional data 
to support the stress test models and improve risk capture.
    As discussed above, several statutory authorities, including the 
International Lending Supervision Act of 1983,\274\ section 5(b) of the 
Bank Holding Company Act,\275\ the International Banking Act,\276\ 
section 10(g) of the Home Owners' Loan Act,\277\ and section 165 of the 
Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank 
Act) \278\ (as amended by section 401 of the Economic Growth, 
Regulatory Relief, and Consumer Protection Act \279\), provide 
authority for the Board's stress testing and stress capital buffer 
framework, including this proposed rule.
---------------------------------------------------------------------------

    \274\ See 12 U.S.C. 3902(1); 3907(a); 3909(a).
    \275\ 12 U.S.C. 1844(b).
    \276\ See 12 U.S.C. 3106.
    \277\ See 12 U.S.C. 1467a(g)(1).
    \278\ Dodd-Frank Act, supra note 2.
    \279\ Economic Growth, Regulatory Relief, and Consumer 
Protection Act, supra note 3.
---------------------------------------------------------------------------

    The International Lending Supervision Act of 1983 provides the 
Board with broad discretionary authority to set minimum capital levels 
for state member banks and affiliates of insured depository 
institutions, including holding companies, supervised by the 
Board.\280\ Under section 5(b) of the Bank Holding Company Act, the 
Board may issue such regulations and orders relating to capital 
requirements of bank holding companies as may be necessary for the 
Board to carry out the purposes of the Bank Holding Company Act.\281\ 
Foreign banking organizations with a U.S. subsidiary bank, branch, or 
agency are made subject by the International Banking Act to the 
provisions of the Bank Holding Company Act in the same manner as bank 
holding companies; \282\ therefore, the Board is also authorized under 
section 5(b) of the Bank Holding Company Act to impose these

[[Page 51938]]

requirements on those foreign banking organizations.
---------------------------------------------------------------------------

    \280\ See 12 U.S.C. 3902(1); 3907(a); 3909(a).
    \281\ 12 U.S.C. 1844(b).
    \282\ See 12 U.S.C. 3106.
---------------------------------------------------------------------------

    Similarly, with regard to savings and loan holding companies, 
section 10(g) of the Home Owners' Loan Act authorizes the Board to 
issue such regulations and orders relating to capital requirements as 
the Board deems necessary and appropriate to carry out the purposes of 
the Home Owners' Loan Act.\283\ Moreover, section 165 of the Dodd-Frank 
Act, as amended by section 401 of the Economic Growth, Regulatory 
Relief, and Consumer Protection Act, requires the Board to establish 
risk-based capital requirements for large bank holding companies and 
nonbank financial companies supervised by the Board.\284\ Additionally, 
section 165(i)(1) of the Dodd-Frank Act, as amended by section 401 of 
the Economic Growth, Regulatory Relief, and Consumer Protection Act, 
requires the Board to conduct an annual supervisory stress test of 
these large firms.\285\
---------------------------------------------------------------------------

    \283\ See 12 U.S.C. 1467a(g)(1).
    \284\ See 12 U.S.C. 5365(b)(1)(A)(i).
    \285\ See 12 U.S.C. 5365(i)(1).
---------------------------------------------------------------------------

    The proposed rule would apply to bank holding companies, U.S. 
intermediate holding companies of foreign banking organizations, and 
savings and loan holding companies, each with at least $100 billion in 
total consolidated assets, as well as state member banks with more than 
$250 billion in total consolidated assets, certain nonbank financial 
companies supervised by the Board, and any other bank holding company 
or covered savings and loan holding company domiciled in the United 
States that is made subject to the capital plan rule by order of the 
Board.\286\ The proposed rule would not apply to any small entities. 
Further, although the Board does not project there to be a direct 
impact to reporting, recordkeeping, or other compliance requirements as 
a result of the proposed rule, the Board also is proposing to revise 
the FR Y-14A/Q/M (Capital Assessments and Stress Testing) reports to 
remove items that are no longer needed to conduct the supervisory 
stress test and to collect data that would improve the calculation of 
the stress capital buffer requirement. These reports are submitted by 
firms subject to the Board's capital plan rule requirements; thus, the 
changes would not impact small entities. In addition, the Board is 
aware of no other Federal rules that duplicate, overlap, or conflict 
with the proposed changes to the capital and stress testing rules. 
Accordingly, the Board believes that the proposed rule will not have a 
significant economic impact on a substantial number of small banking 
organizations supervised by the Board and, therefore, believes that 
there are no significant alternatives to the proposed rule that would 
reduce the economic impact on small banking organizations supervised by 
the Board.
---------------------------------------------------------------------------

    \286\ There currently are no entities with less than $100 
billion in total consolidated assets subject to the capital plan 
rule or to the stress test rules.
---------------------------------------------------------------------------

    The Board welcomes comment on all aspects of its analysis.

C. Plain Language

    Section 722 of the Gramm-Leach-Bliley Act (Pub. L. 106-102, 113 
Stat. 1338, 1471, 12 U.S.C. 4809) requires the federal banking agencies 
to use plain language in all proposed and final rules published after 
January 1, 2000. The Board has sought to present the notice of proposed 
rulemaking in a simple and straightforward manner and invites comment 
on the use of plain language. For example:
     Is the material organized to suit your needs? If not, how 
could the Board present the proposed rule more clearly?
     Are the requirements in the proposed rule clearly stated? 
If not, how could the proposed rule be more clearly stated?
     Does the proposal contain technical language or jargon 
that is not clear? If so, which language requires clarification?
     Would a different format (grouping and order of sections, 
use of headings, paragraphing) make the proposed rule easier to 
understand? If so, what changes would achieve that?
     Is this section format adequate? If not, which of the 
sections should be changed and how?
     What other changes can the Board incorporate to make the 
proposed rule easier to understand?

D. Providing Accountability Through Transparency Act of 2023

    The Providing Accountability Through Transparency Act of 2023 (12 
U.S.C. 553(b)(4)) requires that a notice of proposed rulemaking include 
the internet address of a summary of not more than 100 words in length 
of the proposed rule, in plain language, that shall be posted on the 
internet website under section 206(d) of the E-Government Act of 2002 
(44 U.S.C. 3501 note).
    The proposal and such a summary can be found at https://www.regulations.gov and https://www.federalreserve.gov/supervisionreg/reglisting.htm.

capital buffer requirement most recently provided to the bank holding 
company, except that the value used in paragraph (f)(2)(i)(C)(1) of 
this section will be equal to the bank holding company's planned common 
stock dividends (expressed as a dollar amount) for each of the fifth

    (A) Determine whether the planned capital distributions for the 
fifth through eighth quarters of the planning horizon under the 
Internal baseline scenario would be consistent with effective capital 
distribution limitations assuming the stress capital buffer requirement 
provided by the Board under paragraph (h)(1) or (i)(5) of this section, 
as applicable, in place of any stress capital buffer requirement in 
effect; and
    (1) If the planned capital distributions for the fifth through 
eighth quarters of the planning horizon under the Internal baseline 
scenario would not be consistent with effective capital distribution 
limitations assuming the stress capital buffer requirement provided by 
the Board under paragraph (h)(1) or (i)(5) of this section, as 
applicable, in place of any stress capital buffer requirement in 
effect, the bank holding company must adjust its planned capital 
distributions such that its planned capital distributions would be 
consistent with effective capital distribution limitations assuming the 
stress capital buffer requirement provided by the Board under paragraph 
(h)(1) or (i)(5) of this section, as applicable, in place of any stress 
capital buffer requirement in effect; or
    (2) If the planned capital distributions for the fifth through

scenario would be consistent with effective capital distribution 
limitations assuming the stress capital buffer requirement provided by 
the Board under paragraph (h)(1) or (i)(5) of this section, as 
applicable, in place of any stress capital buffer requirement in 
effect, the bank holding company may adjust its planned capital 
distributions. A bank holding company may not adjust its planned 
capital distributions to be inconsistent with the effective capital 
distribution limitations assuming the stress capital buffer requirement 
provided by the Board under paragraph (h)(1) or (i)(5) of this section, 
as applicable; and
    (B) Notify the Board of any adjustments made to planned capital 
distributions for the fifth through eighth quarters of the planning 
horizon under the Internal baseline scenario.

Appendix A to Part 252--Policy Statement on the Scenario Design 
Framework for Stress Testing

0
18. Appendix A to part 252 is revised to read as follows:

1. Background

    (a) The Board has imposed stress testing requirements through 
its regulations (stress test rules) implementing section 165(i) of 
the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-
Frank Act or Act), section 10(g) of the Home Owners' Loan Act, and 
section 401(e) of the Economic Growth, Regulatory Relief, and 
Consumer Protection Act, and through its capital plan rule (12 CFR 
225.8). Under the stress test rules, the Board conducts a 
supervisory stress test of each bank holding company with total 
consolidated assets of $100 billion or more, intermediate holding 
company of a foreign banking organization with total consolidated 
assets of $100 billion or more, and nonbank financial company that 
the Financial Stability Oversight Council has designated for 
supervision by the Board (together, covered companies).\287\ In 
addition, under the stress test rules, certain firms are also 
subject to company-run stress test requirements.\288\ The Board will 
provide two different sets of conditions (each set, a scenario), 
including baseline and severely adverse scenario for both 
supervisory and company-run stress tests (macroeconomic 
scenarios).\289\
---------------------------------------------------------------------------

    \287\ 12 U.S.C. 5365(i)(1); 12 CFR part 252, subpart E.
    \288\ 12 U.S.C. 5365(i)(2); 12 CFR part 252, subparts B and F.
    \289\ The stress test rules define scenarios as those sets of 
conditions that affect the United States economy or the financial 
condition of a company that the Board determines are appropriate for 
use in stress tests, including, but not limited to, baseline and 
severely adverse scenarios. The stress test rules define baseline 
scenario as a set of conditions that affect the United States 
economy or the financial condition of a company and that reflect the 
consensus views of the economic and financial outlook. The stress 
test rules define severely adverse scenario as a set of conditions 
that affect the U.S. economy or the financial condition of a company 
and that overall are significantly more severe than those associated 
with the baseline scenario and may include trading or other 
additional components.

---------------------------------------------------------------------------

[[Page 51943]]

    (b) The stress test rules provide that the Board will notify 
covered companies by no later than February 15 of each year of the 
scenarios it will use to conduct its supervisory stress tests and 
provide, also by no later than February 15, covered companies and 
other financial companies subject to the final rules the set of 
scenarios they must use to conduct their company-run stress tests. 
Under the stress test rules, the Board may require certain companies 
to use additional components in the severely adverse scenario or 
additional scenarios. For example, the Board expects to require 
large banking organizations with significant trading activities to 
include a trading and counterparty component (market shock, 
described in the following sections) in their severely adverse 
scenario. The Board will provide any additional components or 
scenarios by no later than March 1 of each year.\290\ The Board 
expects that the scenarios it will require the companies to use will 
be the same as those the Board will use to conduct its supervisory 
stress tests (together, stress test scenarios).
---------------------------------------------------------------------------

    \290\ 12 CFR 252.14(b); 12 CFR 252.44(b); 12 CFR 252.54(b).
---------------------------------------------------------------------------

    (c) In addition, Sec.  225.8 of the Board's Regulation Y 
(capital plan rule) requires covered companies to submit annual 
capital plans, including stress test results, to the Board in order 
to allow the Board to assess whether they have robust, forward-
looking capital planning processes and have sufficient capital to 
continue operations throughout times of economic and financial 
stress.\291\
---------------------------------------------------------------------------

    \291\ See 12 CFR 225.8.
---------------------------------------------------------------------------

    (d) Stress tests required under the stress test rules and under 
the capital plan rule require the Board and financial companies to 
calculate pro-forma capital levels--rather than ``current'' or 
actual levels--over a specified planning horizon under baseline and 
stressful scenarios. This approach integrates key lessons of the 
2007-2009 financial crisis and subsequent stress events into the 
Board's supervisory framework. During the financial crisis, investor 
and counterparty confidence in the capitalization of financial 
companies eroded rapidly in the face of changes in the current and 
expected economic and financial conditions, and this loss in market 
confidence imperiled companies' ability to access funding, continue 
operations, serve as a credit intermediary, and meet obligations to 
creditors and counterparties. Importantly, such a loss in confidence 
occurred even when a financial institution's capital ratios were in 
excess of regulatory minimums. This is because the institution's 
capital ratios were perceived as lagging indicators of its financial 
condition, particularly when conditions were changing.
    (e) The stress tests required under the stress test rules and 
capital plan rule are a valuable supervisory tool that provide a 
forward-looking assessment of large financial companies' capital 
adequacy under hypothetical economic and financial market 
conditions. Currently, these stress tests primarily focus on credit 
risk, operational risk, and market risk--that is, risk of mark-to-
market losses associated with companies' trading and counterparty 
positions--and not on other types of risk, such as liquidity risk. 
Pressures stemming from these sources are considered in separate 
supervisory exercises. No single supervisory tool, including the 
stress tests, can provide an assessment of a company's ability to 
withstand every potential source of risk.
    (f) Selecting appropriate scenarios is an especially significant 
consideration for stress tests required under the capital plan rule, 
which ties the review of a company's performance under stress 
scenarios to its ability to make capital distributions. More severe 
scenarios, all other things being equal, generally translate into 
larger projected declines in banks' capital. Thus, a company would 
need more capital today to meet its minimum capital requirements in 
more stressful scenarios and have the ability to continue making 
capital distributions, such as common dividend payments. This 
translation is far from mechanical, however; it will depend on 
factors that are specific to a given company, such as underwriting 
standards and the company's business model, which would also greatly 
affect projected revenue, losses, and capital.

2. Overview and Scope

    (a) This policy statement provides more detail on the 
characteristics of the stress test scenarios and explains the 
considerations and procedures that underlie the approach for 
formulating these scenarios. The considerations and procedures 
described in this policy statement apply to the Board's stress 
testing framework, including to the stress tests required under 12 
CFR part 252, subparts B, E, and F as well as the Board's capital 
plan rule (12 CFR 225.8).\292\
---------------------------------------------------------------------------

    \292\ 12 CFR 252.14(a); 12 CFR 252.44(a); 12 CFR 252.54(a).
---------------------------------------------------------------------------

    (b) Although the Board does not envision that the broad approach 
used to develop scenarios will change from year to year, the stress 
test scenarios will reflect changes in the outlook for economic and 
financial conditions and changes to specific risks or 
vulnerabilities that the Board, in consultation with the other 
federal banking agencies, determines should be considered in the 
annual stress tests. The stress test scenarios should not be 
regarded as forecasts; rather, they are hypothetical paths of 
economic variables that will be used to assess the strength and 
resilience of the companies' capital in various economic and 
financial environments.
    (c) The remainder of this policy statement is organized as 
follows. Section 3 provides a broad description of the baseline and 
severely adverse scenarios and describes the relationship between 
the macroeconomic scenario and the market shock component of the 
severely adverse scenario applicable to companies with significant 
trading activity. This section also describes the types of variables 
that the Board expects to include in the macroeconomic scenarios and 
the market shock component. Section 4 describes the Board's approach 
for developing the macroeconomic scenarios, and section 5 describes 
the approach for the market shocks. Section 6 provides a timeline 
for the formulation and publication of the macroeconomic assumptions 
and market shocks.

3. Content of the Stress Test Scenarios

    (a) The Board will publish two different scenarios, including 
baseline and severely adverse conditions, for use in stress tests 
required in the stress test rules.\293\ In general, the Board 
anticipates that it will not issue additional scenarios. Specific 
circumstances or vulnerabilities that in any given year the Board 
may determine require particular vigilance to help ensure the 
resilience of the banking sector may be captured in the severely 
adverse scenario, and are expected to be explained through the 
comment process in those stress test cycles.
---------------------------------------------------------------------------

    \293\ 12 CFR 252.14(b); 12 CFR 252.44(b); 12 CFR 252.54(b).
---------------------------------------------------------------------------

    (b) While the Board generally expects to use the same scenarios 
for all companies subject to the final rule, it may require a subset 
of companies--depending on a company's financial condition, size, 
complexity, risk profile, scope of operations, or activities, or 
risks to the U.S. economy--to include additional scenario components 
or additional scenarios that are designed to capture different 
effects of adverse events on revenue, losses, and capital. One 
example of such components is the market shock that applies only to 
companies with significant trading activity. Additional components 
or scenarios may also include other stress factors that may not 
necessarily be directly correlated to macroeconomic or financial 
assumptions but nevertheless can materially affect companies' risks, 
such as the unexpected default of a major counterparty.
    (c) Early in each stress testing cycle, the Board plans to 
publish the macroeconomic scenarios along with a brief narrative 
summary that provides a description of the economic situation 
underlying the scenario and explains how the scenarios have changed 
relative to the previous year. In addition, to assist companies in 
projecting the paths of additional variables in a manner consistent 
with the scenario, the narrative will provide descriptions of the 
general path of some additional variables. These descriptions will 
be general--that is, they will describe developments for broad 
classes of variables rather than for specific variables--and will 
specify the intensity and direction of variable changes but not 
numeric magnitudes. These descriptions should provide guidance that 
will be useful to companies in specifying the paths of the 
additional variables for their company-run stress tests. Note that 
in practice it will not be possible for the narrative to include 
descriptions of all the additional variables that companies may need 
for their company-run stress tests. In cases where scenarios are 
designed to reflect particular risks and vulnerabilities, the 
narrative will also explain the underlying motivation for these 
features of the scenario. The Board also plans to release a 
description of the market shock components.

[[Page 51944]]

3.1 Macroeconomic Scenarios

    (a) The macroeconomic scenarios will consist of the future paths 
of a set of economic and financial variables.\294\ The economic and 
financial variables included in the scenarios will likely comprise 
those included in the ``2014 Supervisory Scenarios for Annual Stress 
Tests Required under the Dodd-Frank Act Stress Testing Rules and the 
Capital Plan Rule'' (2013 supervisory scenarios). The domestic U.S. 
variables provided for in the 2013 supervisory scenarios included:
---------------------------------------------------------------------------

    \294\ The future path of a variable refers to its specification 
over a given time period. For example, the path of unemployment can 
be described in percentage terms on a quarterly basis over the 
stress testing time horizon.
---------------------------------------------------------------------------

    (1) Six measures of economic activity and prices: Real and 
nominal gross domestic product (GDP) growth, the unemployment rate 
of the civilian non-institutional population aged 16 and over, real 
and nominal disposable personal income growth, and the Consumer 
Price Index (CPI) inflation rate;
    (2) Four measures of developments in equity and property 
markets: The Core Logic National House Price Index, the National 
Council for Real Estate Investment Fiduciaries Commercial Real 
Estate Price Index, the Dow Jones Total Stock Market Index, and the 
Chicago Board Options Exchange Market Volatility Index; and
    (3) Six measures of interest rates: The rate on the 3-month 
Treasury bill, the yield on the 5-year Treasury bond, the yield on 
the 10-year Treasury bond, the yield on a 10-year BBB corporate 
security, the prime rate, and the interest rate associated with a 
conforming, conventional, fixed-rate, 30-year mortgage.
    (b) The international variables provided for in the 2014 
supervisory scenarios included, for the euro area, the United 
Kingdom, developing Asia, and Japan:
    (1) Percent change in real GDP;
    (2) Percent change in the CPI or local equivalent; and
    (3) The U.S./foreign currency exchange rate.\295\
---------------------------------------------------------------------------

    \295\ The Board may increase the range of countries or regions 
included in future scenarios, as appropriate.
---------------------------------------------------------------------------

    (c) The economic variables included in the scenarios influence 
key items affecting financial companies' net income, including pre-
provision net revenue and credit losses on loans and securities. 
Moreover, these variables exhibit fairly typical trends in adverse 
economic climates that can have unfavorable implications for 
companies' net income and, thus, capital positions.
    (d) The economic variables included in the scenario may change 
over time. For example, the Board may add variables to a scenario if 
the international footprint of companies that are subject to the 
stress testing rules changed notably over time such that the 
variables already included in the scenario no longer sufficiently 
capture the material risks of these companies. Alternatively, 
historical relationships between macroeconomic variables could 
change over time such that one variable (e.g., disposable personal 
income growth) that previously provided a good proxy for another 
(e.g., light vehicle sales) in modeling companies' pre-provision net 
revenue or credit losses ceases to do so, resulting in the need to 
create a separate path, or alternative proxy, for the other 
variable. However, recognizing the amount of work required for 
companies to incorporate the scenario variables into their stress 
testing models, the Board expects to eliminate variables from the 
scenarios only in rare instances.
    (e) The Board expects that the company may not use all of the 
variables provided in the scenario, if those variables are not 
appropriate to the company's line of business, or may add additional 
variables, as appropriate. The Board expects the companies to ensure 
that the paths of such additional variables are consistent with the 
scenarios the Board provided. For example, the companies may use, as 
part of their internal stress test models, local-level variables, 
such as state-level unemployment rates or city-level house prices. 
While the Board does not plan to include local-level macro variables 
in the stress test scenarios it provides, it expects the companies 
to evaluate the paths of local-level macro variables as needed for 
their internal models, and ensure internal consistency between these 
variables and their aggregate, macro-economic counterparts. The 
Board will provide the macroeconomic scenario component of the 
stress test scenarios for a period that spans a minimum of 13 
quarters. The scenario horizon reflects the supervisory stress test 
approach that the Board plans to use. Under the stress test rules, 
the Board will assess the effect of different scenarios on the 
consolidated capital of each company over a forward-looking planning 
horizon of at least nine quarters.

3.2 Market Shock Component

    (a) The market shock component of the severely adverse scenario 
will only apply to companies with significant trading activity and 
their subsidiaries.\296\ The component consists of large moves in 
market prices and rates that would be expected to generate losses. 
Market shocks differ from macroeconomic scenarios in several ways, 
both in their design and application. For instance, market shocks 
that might typically be observed over an extended period (e.g., 3 
months) are assumed to affect the market value of the companies' 
trading assets and liabilities immediately. In addition, under the 
stress test rules, the as-of date for market shocks will differ from 
the quarter-end, and the Board will provide the as-of date for 
market shocks no later than February 1 of each year. Finally, as 
described in section 4, the market shock includes a much larger set 
of risk factors than the set of economic and financial variables 
included in macroeconomic scenarios. Broadly, these risk factors 
include shocks to financial market variables that affect asset 
prices, such as a credit spread or the yield on a bond, and, in some 
cases, the value of the position itself (e.g., the market value of 
securitized positions).
---------------------------------------------------------------------------

    \296\ Currently, companies with significant trading activity 
include any bank holding company or intermediate holding company 
that (1) has aggregate trading assets and liabilities of $50 billion 
or more, or aggregate trading assets and liabilities equal to 10 
percent or more of total consolidated assets, and (2) is not a 
Category IV firm. The Board may also subject a state member bank 
subsidiary of any such bank holding company to the market shock 
component. The set of companies subject to the market shock 
component could change over time as the size, scope, and complexity 
of financial company's trading activities evolve.
---------------------------------------------------------------------------

    (b) The Board envisions that the market shocks will include 
shocks to a broad range of risk factors that are similar in 
granularity to those risk factors that trading companies use 
internally to produce profit and loss estimates, under stressful 
market scenarios, for all asset classes that are considered trading 
assets, including public equities, credit, interest rates, foreign 
exchange rates, and commodities. Examples of risk factors include, 
but are not limited to:
    (1) Public equity indices to which companies with significant 
trading activity may have exposure, along with term structures of 
implied volatilities;
    (2) Cross-currency foreign exchange rates of selected 
currencies, along term structures of implied volatilities;
    (3) Term structures of government rates (e.g., U.S. Treasuries), 
interbank rates (e.g., swap rates) and potentially other key rates 
(e.g., commercial paper) for developed markets and for developing 
and emerging market nations to which companies may have exposure;
    (4) Term structures of implied volatilities that are key inputs 
to the pricing of interest rate derivatives;
    (5) Term structures of futures prices for energy products 
including crude oil (differentiated by country of origin), natural 
gas, and power;
    (6) Term structures of futures prices for metals and 
agricultural commodities; and
    (7) Credit spreads or instrument prices for credit-sensitive 
product segments including: corporate bonds, credit default swaps, 
and collateralized debt obligations by risk; non-agency residential 
mortgage-backed securities and commercial mortgage-backed securities 
by risk and vintage; sovereign debt; and, municipal bonds.

4. Approach for Formulating the Macroeconomic Assumptions for Scenarios

    (a) This section describes the Board's approach for formulating 
macroeconomic assumptions for each scenario. The methodologies for 
formulating this part of each scenario differ by scenario, so these 
methodologies for the baseline and severely adverse scenarios are 
described separately in each of the following subsections.
    (b) In general, the baseline scenario will reflect the most 
recently available consensus views of the macroeconomic outlook 
expressed by professional forecasters, government agencies, and 
other public-sector organizations as of the beginning of the stress-
test cycle. The severely adverse scenario will consist of a set of 
economic and financial conditions that reflect the conditions of 
post-war U.S. recessions.
    (c) Each of these scenarios is described further in sections 
below as follows: Baseline (subsection 4.1) and severely adverse 
(subsection 4.2)

[[Page 51945]]

4.1 Approach for Formulating Macroeconomic Assumptions in the 
Baseline Scenario

    (a) The stress test rules define the baseline scenario as a set 
of conditions that affect the U.S. economy or the financial 
condition of a banking organization, and that reflect the consensus 
views of the economic and financial outlook. Projections under a 
baseline scenario are used to evaluate how companies would perform 
in more likely economic and financial conditions. The baseline 
serves also as a point of comparison to the severely adverse 
scenario, giving some sense of how much of the company's capital 
decline could be ascribed to the scenario as opposed to the 
company's capital adequacy under expected conditions.
    (b) The baseline scenario will be developed around a 
macroeconomic projection that captures the prevailing views of 
private-sector forecasters (e.g., Blue Chip Consensus Forecasts and 
the Survey of Professional Forecasters), government agencies, and 
other public-sector organizations (e.g., the International Monetary 
Fund and the Organization for Economic Co-operation and Development) 
near the beginning of the annual stress-test cycle. The baseline 
scenario is designed to represent a consensus expectation of certain 
economic variables over the time period of the tests and it is not 
the Board's internal forecast for those economic variables. For 
example, the baseline path of short-term interest rates is 
constructed from consensus forecasts and may differ from that 
implied by the Federal Open Market Committee's Summary of Economic 
Projections.
    (c) For some scenario variables--such as U.S. real GDP growth, 
the unemployment rate, and the consumer price index--there will be 
many different forecasts available to project the paths of these 
variables in the baseline scenario. For others, a more limited 
number of forecasts will be available. If available forecasts 
diverge notably, the baseline scenario will reflect an assessment of 
the forecast that is deemed to be most plausible. The Board also 
considers the output of a macroeconomic model, for which the Board 
will maintain a description separately on the Board's website, 
developed by Board staff for use in constructing the values of some 
of the variables in the scenarios for the annual stress test. In 
setting the paths of variables in the baseline scenario, particular 
care will be taken to ensure that, together, the paths present a 
coherent and plausible outlook for the U.S. and global economy, 
given the economic climate in which they are formulated. However, 
the macroeconomic model was designed to meet the specific needs of 
the stress testing program, and the resulting baseline scenarios are 
not Federal Reserve forecasts.

4.2 Approach for Formulating the Macroeconomic Assumptions in the 
Severely Adverse Scenario

    The stress test rules define a severely adverse scenario as a 
set of conditions that affect the U.S. economy or the financial 
condition of a financial company and that overall are significantly 
more severe than those associated with the baseline scenario. The 
financial company will be required to publicly disclose a summary of 
the results of its stress test under the severely adverse scenario, 
and the Board intends to publicly disclose the results of its 
analysis of the financial company under the severely adverse 
scenario.

4.2.1 General Approach: The Recession Approach

    (a) The Board intends to use a recession approach to develop the 
severely adverse scenario. In the recession approach, the Board will 
specify the future paths of variables to reflect conditions that 
characterize post-war U.S. recessions, generating either a typical 
or specific recreation of a post-war U.S. recession. The Board chose 
this approach because it has observed that the conditions that 
typically occur in recessions--such as increasing unemployment, 
declining asset prices, and contracting loan demand--can put 
significant stress on companies' balance sheets. This stress can 
occur through a variety of channels, including higher loss 
provisions due to increased delinquencies and defaults; losses on 
trading positions through sharp moves in market prices; and lower 
bank income through reduced loan originations. For these reasons, 
the Board believes that the paths of economic and financial 
variables in the severely adverse scenario should, at a minimum, 
resemble the paths of those variables observed during a recession.
    (b) This approach requires consideration of the type of 
recession to feature. All post-war U.S. recessions have not been 
identical: Some recessions have been associated with very elevated 
interest rates, some have been associated with sizable asset price 
declines, and some have been relatively more global. Recessions that 
are caused by or exacerbated by a financial crisis often are deeper 
and more protracted than other recessions. The Board therefore 
believes that the severely adverse scenario should be triggered by a 
sudden and substantial increase in risk aversion and uncertainty 
that causes sharp declines in risky financial asset prices, lower 
interest rates on safe assets, and a rise in volatility big enough 
to disrupt functioning in some markets. Although markets resume 
normal functioning within a few months, the rise in uncertainty and 
decline in wealth causes businesses to take nearly simultaneous 
steps to reduce employment and investment and households to reduce 
spending. Negative feedback effects between contracting economic 
activity and financial markets' response lead to a deep and 
prolonged decline in overall economic activity, inflation, and asset 
prices followed by a shallow recovery.
    (c) Indeed, the most common features of recessions are increases 
in the unemployment rate and contractions in aggregate incomes and 
economic activity. For this and the following reasons, the Board 
intends to use a rise in the unemployment rate as the primary basis 
for calibrating the severity of the severely adverse scenario. 
First, the unemployment rate is likely the most representative 
single summary indicator of adverse economic conditions. Second, in 
comparison to GDP, labor market data have traditionally featured 
more prominently than GDP in the set of indicators that the National 
Bureau of Economic Research reviews to inform its recession 
dates.\297\ Third and finally, the growth rate of potential output 
can cause the size of the decline in GDP to vary between recessions. 
While changes in the unemployment rate can also vary over time due 
to demographic factors, this seems to have more limited implications 
over time relative to changes in potential output growth. The 
unemployment rate used in the severely adverse scenario will reflect 
an unemployment rate that has been observed in severe post-war U.S. 
recessions, measuring severity by the absolute level of and relative 
increase in the unemployment rate.\298\
---------------------------------------------------------------------------

    \297\ More recently, a monthly measure of GDP has been added to 
the list of indicators.
    \298\ Even though all recessions feature increases in the 
unemployment rate and contractions in incomes and economic activity, 
the size of this change has varied over post-war U.S. recessions. 
Table 1 documents the variability in the depth of post-war U.S. 
recessions. Some recessions--labeled mild in Table 1--have been 
relatively modest, with GDP edging down just slightly and the 
unemployment rate moving up about a percentage point. Other 
recessions--labeled severe in Table 1--have been much harsher, with 
GDP dropping 3.75 percent and the unemployment rate moving up a 
total of about 4 percentage points.
---------------------------------------------------------------------------

    (d) The Board believes that the severely adverse scenario should 
also reflect a housing recession. The house prices path set in the 
severely adverse scenario will reflect developments that have been 
observed in post-war U.S. housing recessions, measuring severity by 
the absolute level of and relative decrease in the house prices.
    (e) As described below, the Board has developed guides for 
several additional variables including equity prices, the Chicago 
Board Options Exchange's Volatility Index (VIX), BBB spread, 
mortgage rate spread, commercial real estate prices, and 5-year and 
10-year Treasury yields. The international variables (GDP, 
inflation, and exchange rates) are also subject to guides.
    (f) The Board will specify the paths of those other 
macroeconomic and financial market variables based on their behavior 
during previous recessions or other periods of financial stress, as 
well as informed assessments of how that behavior co-moved with the 
paths of unemployment, income, house prices, and activity during 
periods of macrofinancial stress. Some of these other variables, 
however, have taken divergent paths in previous recessions (e.g., 
foreign GDP). The analysis that the Board conducted to develop the 
guides informed its judgment in selecting the appropriate ranges for 
the peak or trough, the timing of that peak or trough, and ending 
values, as well as the trajectory of these variables between the 
starting and ending values. In general, the path for these variables 
also will be based on their underlying structure at the time that 
the scenario is designed (e.g., economic or financial-system 
vulnerabilities in other countries).
    (g) The Board considered alternative methods for scenario design 
of the severely adverse scenario, including a probabilistic 
approach. The probabilistic approach constructs a baseline forecast 
from a large-

[[Page 51946]]

scale macroeconomic model and identifies a scenario that would have 
a specific probabilistic likelihood given the baseline forecast. The 
Board believes that, at this time, the recession approach is better 
suited for developing the severely adverse scenario than a 
probabilistic approach because it guarantees a recession of some 
specified severity. In contrast, the probabilistic approach requires 
the choice of an extreme tail outcome--relative to baseline--to 
characterize the severely adverse scenario (e.g., a 5 percent or a 1 
percent tail outcome). In practice, this choice is difficult as 
adverse economic outcomes are typically thought of in terms of how 
variables evolve in an absolute sense rather than how far away they 
lie in the probability space away from the baseline. In this sense, 
a scenario featuring a recession may be somewhat clearer and more 
straightforward to communicate. Finally, the probabilistic approach 
relies on estimates of uncertainty around the baseline scenario and 
such estimates are in practice model-dependent.

4.2.2 Setting Variables in the Severely Adverse Scenario

    (a) Generally, the variables in the severely adverse scenario 
will be specified to be consistent with their expected behavior in 
severe recessions or periods of market stress. The approach for 
specifying the paths of these variables in the scenario will reflect 
the Board's assessment of:
    (1) how economic models suggest that these variables should 
evolve given the path of the unemployment rate,
    (2) how these variables have typically evolved in past U.S. 
recessions or other relevant periods of significant stress in 
particular asset markets, and
    (3) other relevant factors, including the current state of the 
economy; the level of vulnerabilities in the financial system; and 
consensus estimates of long-run equilibrium values of potential GDP, 
interest rates, and inflation expectations.
    (b) For certain variables subject to guides that provide a range 
or potential values (BBB spread, VIX, commercial real estate prices, 
and mortgage rate), the Board expects that it could be appropriate 
to set the paths for these variables at similar levels of severity. 
In making this determination, the Board would consider the expected 
severity of the unemployment rate and house prices variables and the 
prevailing macroeconomic and financial conditions described in the 
baseline scenario.
    (c) The expected trajectories for the variables related to 
unemployment, long-term bond yields and spreads, asset prices, and 
volatility will be informed by quantitative guides. These guides 
provide plausible ranges within which the Board expects to choose 
the level of the peak or trough that each of these variables will 
reach in the scenario, the timing of that peak or trough, the value 
of the variable at the end of the scenario, and the trajectory of 
the variable between the starting and ending value. The Board's 
choices within those ranges will be informed by the factors listed 
in section (a), above.
    (d) Economic models--such as medium-scale macroeconomic models--
should be able to generate plausible paths consistent with the 
unemployment rate for a number of scenario variables, such as real 
GDP growth, CPI inflation, and short-term interest rates, which have 
relatively stable (direct or indirect) relationships with the 
unemployment rate (e.g., Okun's Law, the Phillips Curve, and 
interest rate feedback rules). The Board has developed a model 
specifically structured and calibrated to the needs of the stress 
testing program to inform the trajectories of these variables (as 
well as disposable personal income, or DPI), a description of which 
will be maintained on the Board's website. The output of this model 
is not a forecast of the Federal Reserve.
    (e) In addition, judgment is necessary in projecting the path of 
a scenario's international variables. Recessions that occur 
simultaneously across countries are an important source of stress to 
the balance sheets of companies with notable international exposures 
but are not a typical feature of the international economy even when 
the U.S. is in recession. As a result, simply adopting the typical 
path of international variables in a severe U.S. recession would 
likely underestimate the risks stemming from the international 
economy. Consequently, an approach that uses both judgment and 
economic models informs the path of international variables.
    (f) The Board expects that the variables described in this 
section 4.2.2 will be specified in the annual scenarios in the 
severely adverse scenario to be consistent with the guides for each 
variable below. In designing these guides and setting the values for 
the variables in the severely adverse scenario, the Board will 
consider the following scenario design principles:
    (1) Severity: The scenarios should be sufficiently severe. 
Severity is an important component in ensuring that covered 
companies are adequately capitalized against a hypothetical severe 
recession and in maintaining the public credibility of stress tests. 
In determining the adequate level of severity for these guides, the 
principle of severity requires that, at times, variable paths may 
exceed levels observed in the historical data. Since no single 
scenario can account for all potential contingencies, the scenario 
must be sufficiently severe to ensure that banks will be resilient 
to a range of alternative and plausible scenarios that could 
generate net losses that are of similar magnitudes, even if such 
scenarios would have different characteristics from the single 
annual scenario. In establishing a sufficiently severe scenario, the 
Board considers the potential unintended effects of the scenario on 
the operations of firms subject to the stress tests.
    (2) Credibility: The scenarios should be credible. Credible 
stress tests maintain the confidence of the public and financial 
markets that the stress tests are sufficiently severe to ensure that 
the firms are properly capitalized to withstand severe economic and 
financial conditions.
    (3) Avoiding adding procyclicality: The scenarios should avoid 
adding sources of procyclicality. If stress tests are relatively 
more severe in already stressed conditions, then this severity could 
add undue stress to the financial system, reducing financial 
intermediation with negative implications for the macroeconomy. The 
stress tests should balance the need for an adequately severe 
scenario without magnifying existing procyclical tendencies in the 
financial system.
    (4) Flexibility: While the Board's scenario design framework 
promotes transparency and predictability, fixed guides often would 
fail to achieve at least one of the Board's goals of severity, 
credibility, and not adding to procyclicality, as well as the 
principles established in the Board's Stress Testing Policy 
Statement.\299\ As a result, the Board has designed guides in this 
section that generally establish ranges of historically observed 
values that can be selected for a given severely adverse scenario, 
while also enabling the Board to consider unexpected shocks that may 
have implications for the economy and the financial stability of the 
United States, and therefore, firms' future financial condition. 
Further, flexibility is important to enable the Board to implement 
reasonable technical adjustments to the values and trajectories of 
the variables, consistent with these scenario design principles.

---------------------------------------------------------------------------

    (g) The guides described in this section set out paths for each 
variable over the 13 quarters in the severely adverse scenario. The 
stress test requires projections of 13 quarters' worth of losses to 
determine capital ratios at the end of 9 quarters of the scenario, 
because loss provisions in quarter 9 are affected by bank 
performance in quarters 10 to 13. To describe these paths, most 
guides adopt a simple framework involving the following 4 
parameters:
    (1) the jump-off value: the value of the variable in the quarter 
preceding the scenario. The jump-off value will be set to reflect 
the conditions at the time that the scenario is designed.
    (2) the peak or trough value: the paths in each guide specify 
that each variable in the scenario will either increase or decrease 
from its jump-off value. If the variable increases, it will reach a 
maximum or peak value during the scenario. If it decreases, it will 
reach a minimum or trough value during the scenario.
    (3) the timing of the peak or trough: the quarter of the 
scenario in which the variable path reaches its peak or trough.
    (4) the trajectory from jump-off to peak or trough: the values 
between the jump-off and peak or trough will be determined with a 
roughly linear interpolation, a nonlinear function, or by specifying 
the proportion of the change from jump-off to peak or trough that 
will obtain in each of the intervening quarters.
    (h) The severely adverse scenario will also set out end values 
and trajectories to end values. The end value is expected to 
generally be consistent with the historical values of a given 
variable within a 10 to 15 quarter window after the beginning of 
either a recession or other identified stress event. The trajectory 
from peak or trough to end value is expected to generally be 
determined by a roughly linear interpolation. The trajectory from 
the peak or trough to the end

[[Page 51947]]

value generally will be smooth for variables determined by guides 
and follow the model path for modeled variables.

4.2.2.1 Setting the Unemployment Rate Under the Severely Adverse 
Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature an unemployment rate peak value that increases between 
3 to 5 percentage points from its jump-off value. However, if a 3 to 
5 percentage point increase in the unemployment rate does not raise 
the level of the unemployment rate to at least 10 percent, the path 
of the unemployment rate in most cases will be specified so as to 
raise the unemployment rate to at least 10 percent.
    (b) The Board anticipates that the unemployment rate peak value 
will occur between quarters 6 and 8 after the jump-off point for the 
scenario. The trajectory to peak value is expected to experience 
high initial changes with smaller subsequent changes quarter to 
quarter.

4.2.2.2 Setting House Prices in the Severely Adverse Scenario

    (a) In specifying the path for nominal house prices, the Board 
will consider the ratio of the nominal house price index (HPI) to 
nominal per capita DPI. The Board anticipates that the severely 
adverse scenario will feature an HPI-DPI ratio that falls by at 
least 25 percent, or enough to bring the ratio down to the trough 
reached in the first quarter of 2012 after the 2007-2009 financial 
crisis.
    (b) The trough is expected to occur between quarter 8 and 
quarter 10 after the jump-off quarter. The trajectory to trough 
value is expected to experience 20 percent of the decline realized 
in quarter 1 and another 20 percent of the decline in quarter 2 (40 
percent in total), with a roughly linear trajectory to trough 
thereafter.

4.2.2.3 Setting the BBB Spread for the Severely Adverse Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature a BBB corporate spread value, defined as the difference 
between the yield on BBB corporate bonds and the 10-year Treasury 
yield, that increases to the higher of (1) between a spread level of 
500 to 600 basis points, or (2) a total increase of about 100 basis 
points from the jump-off value.
    (b) The Board anticipates that the BBB spread peak value will 
occur between quarters 3 and 4 after the jump-off point for the 
scenario. The trajectory to peak value is expected to experience the 
highest share of the increase in quarters 1 and 2, with between 60 
and 80 percent of the increase in quarter 1, followed by a smooth 
trajectory to peak thereafter.

4.2.2.4 Setting the Mortgage Rate for the Severely Adverse Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature a mortgage rate spread value, relative to the 10-year 
Treasury yield, that increases between 70 to 160 basis points from 
its initial level. The initial level will be set based on the 
conditions at the time that the scenario is designed. However, if a 
70 to 160 basis point increase in the mortgage rate spread does not 
raise the level of the mortgage rate spread to at least 280 basis 
points, the path of the mortgage rate spread in most cases will be 
specified so as to raise the mortgage rate spread to at least 280 
basis points.
    (b) The Board anticipates that the mortgage rate spread peak 
value will occur between quarters 3 and 4 after the jump-off point 
for the scenario. The trajectory to peak value is expected to 
experience between 50 and 70 percent of the increase realized in 
quarter 1, with a smooth trajectory to peak thereafter.

4.2.2.5 Setting the VIX for the Severely Adverse Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature a VIX peak value that will increase to a level between 
65 and 75 percent or by at least 10 percentage points from the jump-
off value, whichever results in a higher level.
    (b) The Board anticipates that the VIX peak value will occur in 
quarter 2 after the jump-off point for the scenario. The trajectory 
to peak value is expected to experience the largest share of the 
increase, of 60 to 80 percent, in quarter 1.

4.2.2.6 Setting Equity Prices for the Severely Adverse Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature an equity price value that falls by around 50 percent 
plus or minus up to 10 percent, depending on the performance of 
equity prices over the 12-month period prior to the jump-off value. 
When equity prices have risen over the past 12 months, equity prices 
will fall to a trough level below the jump-off value of 50 percent 
plus one half of the percentage increase in equity prices up to a 
maximum of 10 percent. When equity prices have decreased over the 
past 12 months, equity prices will fall to a trough level below the 
jump-off value of 50 percent minus one half of the percentage 
decrease in equity prices, up to a maximum of 10 percent. Thus, the 
equity prices reach a trough level of between 40 and 60 percent 
below the jump-off value.
    (b) The Board anticipates that the equity price trough value 
will occur in quarter 3 or 4 after the jump-off point for the 
scenario. The trajectory to trough value is expected to experience 
the highest share of the decrease, 60 to 70 percent, in quarter 1, 
with 10 to 20 percent of the decline occurring in quarter 2 and the 
remaining decline realized about equally in the remaining quarter(s) 
to the trough value.

4.2.2.7 Setting CRE Prices for the Severely Adverse Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature a CRE price value that falls between 30 and 45 percent 
from its jump-off value.
    (b) The Board anticipates that the CRE trough value will occur 
between 8 and 10 quarters after the jump-off value for the scenario. 
The trajectory to trough value is expected to be roughly linear.

4.2.2.8 Setting the 5-Year Treasury Yield for the Severely Adverse 
Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature a 5-year Treasury yield value that falls between 1.5 
and 3.5 percentage points from its jump-off value, subject to a 
lower bound of 0.3 percent, or a decline of 0.25 percent from the 
jump-off level, whichever is lower.
    (b) The Board anticipates that the 5-year Treasury yield trough 
value will occur between 1 and 4 quarters after the jump-off value 
for the scenario. The trajectory to trough value is expected to 
experience the highest share of the decrease in quarter 1, depending 
on the quarter that the trough value will occur, such that the share 
of the decrease in quarter 1 will be between 55 percent and 100 
percent. If the trough value is set to occur in quarters 2, 3, or 4, 
the yield decline trajectory following quarter 1 will decrease 
smoothly to the trough quarter.

4.2.2.9 Setting the 10-Year Treasury Yield for the Severely Adverse 
Scenario

    (a) The Board anticipates that the severely adverse scenario 
will feature a 10-year Treasury yield value that falls between 1 and 
3 percentage points from its jump-off value, subject to a lower 
bound of 0.5 percent, or a decline of 0.25 percent from the jump-off 
level, whichever is lower.
    (b) The Board anticipates that the 10-year Treasury yield trough 
value will occur between 1 and 4 quarters after the jump-off value 
for the scenario. The trajectory to trough value is expected to 
experience the highest share of the decrease in quarter 1, depending 
on the quarter that the trough value will occur, such that the share 
of the decrease in quarter 1 will be between 55 percent and 100 
percent. If the trough value is set as quarters 2, 3, or 4, the 
yield decline trajectory following quarter 1 will decrease smoothly 
to the trough quarter.

4.2.2.10 Setting the Calibration of International Variables

    (a) The Board expects to calibrate values for certain 
international variables in the euro area, the United Kingdom, Japan, 
and Developing Asia.
    (b) For the euro area, the Board expects in general to specify 
that GDP will decline by 7.5 percent from the baseline value to its 
trough in the scenario, and reach an end value of 7.5 percent below 
the baseline value. However, the Board may choose a value for the 
decline in GDP between 5 and 10 percent. The Board expects to 
specify that euro area inflation will decline by 3 percentage points 
from the baseline scenario to its trough, and reach an end value of 
0 percentage points below the baseline value. However, the Board may 
choose a value for the decline in inflation between 2 and 4 
percentage points. The Board expects to specify that the U.S. dollar 
will appreciate against the euro by approximately 15 percent from 
its jump-off value at its peak and then revert back to the jump-off 
value by the end of the scenario. However, the Board may choose a 
value for U.S. dollar appreciation between 5 and 25 percent(c).
    For the United Kingdom, the Board expects in general to specify 
that GDP will decline by 7.5 percent from the baseline value to its 
trough in the scenario, and reach an end value of 7.5 percent below 
the baseline value. However, the Board may choose a value for the 
decline in GDP between 5 and 10 percent. The Board expects to 
specify that inflation will decline by 3 percentage points from the

[[Page 51948]]

baseline value to its trough, and reach an end value of 0 percentage 
points below the baseline value. However, the Board may choose a 
value for the decline in inflation between 2 and 4 percentage 
points. The Board expects to specify that the U.S. dollar will 
appreciate against the Great Britain Pound by 15 percent from its 
jump-off value at its peak and then revert back to the jump-off 
value by the end of the scenario. However, the Board may choose a 
value for U.S. dollar appreciation between 5 and 25 percent.
    (d) For Japan, the Board expects in general to specify that GDP 
will decline by 7.5 percent from the baseline value to its trough in 
the scenario, and reach an end value of 7.5 percent below the 
baseline value. However, the Board may choose a value for the 
decline in GDP between 5 and 10 percent. The Board expects to 
specify that inflation will decline by 3 percentage points from the 
baseline value to its trough, and reach an end value of 0 percentage 
points below the baseline value. However, the Board may choose a 
value for the decline in inflation between 2 and 4 percentage 
points. The Board expects to specify that U.S. dollar will 
depreciate against the Japanese yen by 1 percent from its jump-off 
value at its peak and then revert back to the jump-off value by the 
end of the scenario. However, the Board may choose a value for 
change in value of the U.S. dollar against the Japanese yen ranging 
from a 9 percent depreciation to an 11 percent appreciation.
    (e) For Developing Asia, the Board expects in general to specify 
that GDP will decline by 3 percent from the baseline value to its 
trough, and reach an end value of 0 percent below the baseline 
value. However, the Board may choose a value for the decline in GDP 
between 0.5 and 5.5 percent. The Board expects to specify that 
inflation will decline by 5 percentage points from the baseline 
value to its trough, and reach an end value of 0 percentage points 
below the baseline value. However, the Board may choose a value for 
the decline in inflation between 0.8 and 9 percentage points. The 
Board expects to specify that the U.S. dollar will appreciate 
against the currencies in Developing Asia by 15 percent from its 
jump-off value at its peak and then revert back to the jump-off 
value by the end of the scenario. However, the Board may choose a 
value for the appreciation of the U.S. dollar between 5 and 25 
percent.

4.2.3 Adding Salient Risks to the Severely Adverse Scenario

    (a) The severely adverse scenario will be developed to reflect 
specific risks to the economic and financial outlook that are 
especially salient but that would feature minimally in the scenario 
if the Board were to use only approaches that looked to past 
recessions or relied on historical relationships between variables.
    (b) There are some important instances in which it will be 
appropriate to augment the recession approach with salient risks. 
For example, if an asset price were especially elevated and thus 
potentially vulnerable to an abrupt and potentially destabilizing 
decline, it would be appropriate to include such a decline in the 
scenario even if such a large drop were not typical in a severe 
recession. Likewise, if economic developments abroad were 
particularly unfavorable, assuming a weakening in international 
conditions larger than what typically occurs in severe U.S. 
recessions would likely also be appropriate.
    (c) Clearly, while the recession component of the severely 
adverse scenario is within some predictable range, the salient risk 
aspect of the scenario is far less so, and therefore, needs an 
annual assessment. Each year, the Board will identify the risks to 
the financial system and the domestic and international economic 
outlooks that appear more elevated than usual, using its internal 
analysis and supervisory information and in consultation with the 
Federal Deposit Insurance Corporation (FDIC) and the Office of the 
Comptroller of the Currency (OCC). Using the same information, the 
Board will then calibrate the paths of the macroeconomic and 
financial variables in the scenario to reflect these risks.
    (d) The Board will factor in particular risks to the domestic 
and international macroeconomic outlook identified by its 
economists, bank supervisors, and financial market experts and make 
appropriate adjustments to the paths of specific economic variables. 
These adjustments will not be reflected in the general severity of 
the recession and, thus, all macroeconomic variables; rather, the 
adjustments will apply to a subset of variables to reflect co-
movements in these variables that are historically less typical. The 
Board plans to discuss the motivation for the adjustments that it 
makes to variables to highlight systemic risks in the narrative 
describing the scenarios, which will be released for public comment 
and subsequently adjusted, if necessary, in response to those 
comments.\300\
---------------------------------------------------------------------------

    \300\ The means of effecting an adjustment to the severely 
adverse scenario to address salient systemic risks differs from the 
means used to adjust variables within the ranges specified by the 
guides or the paths suggested by the macroeconomic model. For 
example, in adjusting the scenario for an increased unemployment 
rate, the Board would modify all variables such that the future 
paths of the variables would be similar to how these variables have 
moved historically in response to a change in the unemployment rate. 
In contrast, to address salient risks, the Board may only modify a 
small number of variables in the scenario and, as such, their future 
paths in the scenario would be somewhat more atypical, but not 
implausible, given existing risks.
---------------------------------------------------------------------------

5. Approach for Formulating the Market Shock Component

    (a) This section discusses the approach the Board proposes to 
adopt for developing the market shock component of the severely 
adverse scenario appropriate for companies with significant trading 
activities. The design and specification of the market shock 
component differs from that of the macroeconomic scenarios because 
profits and losses from trading are measured in mark-to-market 
terms, while revenues and losses from traditional banking are 
generally measured using the accrual method. As noted above, another 
critical difference is the time-evolution of the market shock 
component. The market shock component consists of a sudden ``shock'' 
to a large number of risk factors that determine the mark-to-market 
value of trading positions, while the macroeconomic scenarios supply 
a projected path of economic variables that affect traditional 
banking activities over the entire planning period.
    (b) The development of the market shock component that are 
detailed in this section are as follows: baseline (subsection 5.1) 
and severely adverse (subsection 5.2).

5.1 Approach for Formulating the Market Shock Component Under the 
Baseline Scenario

    Market shocks are large, previously unanticipated moves in asset 
prices and rates. Under the baseline scenario, asset prices should, 
broadly speaking, reflect consensus opinions about the future 
evolution of the economy. Sudden price movements, as envisioned in 
the market shock, should not occur along the baseline path. As a 
result, the market shock will not be included in the baseline 
scenario.

5.2 Approach for Formulating the Market Shock Component Under the 
Severely Adverse Scenario

    This section addresses possible approaches to designing the 
market shock component in the severely adverse scenario, including 
important considerations for scenario design, possible approaches to 
designing scenarios, and a development strategy for implementing the 
preferred approach.

5.2.1 Design Considerations for Market Shocks

    (a) The general market practice for stressing a trading 
portfolio is to specify market shocks either in terms of changes to 
observable, broad financial market indicators and risk factors or 
directly as changes to the mark-to-market values of financial 
instruments.
    (b) While the number of market shocks used in companies' pricing 
and stress-testing models typically exceeds that provided in the 
Board's scenarios, the number of market shocks in the Board's 
scenarios allows for the consistency and comparability of market 
losses across companies. However, the benefit from specifying a 
large set of market shocks is at least partly offset by the 
potential difficulty in creating shocks that are coherent and 
internally consistent, particularly as the framework for developing 
market shocks deviates from historical events. The Board's process 
for generating the scenario market shocks has developed over time to 
rely less on models and has expanded its use of simpler methods, 
such as multipliers and mappings to modeled risk factors.
    (c) Also, importantly, the ultimate losses associated with a 
given market shock will depend on a company's trading positions, 
which can make it difficult to rank order, ex ante, the severity of 
the scenarios. In certain instances, market shocks that include 
large market moves may not be particularly stressful for a given 
company. Aligning the market shock with the macroeconomic scenario 
for consistency may result in certain companies actually benefiting 
from risk factor moves of larger magnitude in the market scenario if 
the companies are hedging against salient risks to other parts of 
their

[[Page 51949]]

business. Thus, the severity of market shocks must be calibrated to 
take into account how a complex set of risks, such as directional 
risks and basis risks, interacts with each other, given the 
companies' trading positions at the time of stress. For instance, a 
large depreciation in a foreign currency would benefit companies 
with net short positions in the currency while hurting those with 
net long positions. In addition, longer maturity positions may move 
differently from shorter maturity positions, adding further 
complexity.
    (d) The sudden nature of market shocks and the early recognition 
of mark-to-market losses add another element to the design of market 
shocks, and to determining the appropriate severity of shocks. The 
design of the market shocks must factor in appropriate assumptions 
around the period of time during which market events will unfold and 
any associated market responses.
    (e) The design of market shocks includes calibration of shock 
magnitudes based on assumed time horizons that reflect several 
scenario design considerations. One consideration is the liquidity 
characteristics of different asset classes. More specifically, the 
calibration horizons reflect the variation in speed at which banks 
could reasonably close out, or effectively hedge, the associated 
risk exposures in the event of a market stress. The horizons are 
generally longer than the typical times needed to liquidate 
exposures under normal conditions because they are designed to 
capture the unpredictable liquidity conditions that prevail in times 
of stress. Another consideration is maintaining consistency between 
the assumed time horizons used to calibrate market shocks and the 
timeline for attributing the losses stemming from them. 
Specifically, losses associated with the global market shock 
component are attributed in one quarter of the stress test horizon, 
which implies an upper bound of three months for calibrating the 
shocks.
    (f) Given these considerations, shock liquidity horizons are 
chosen to be broadly consistent with the proposed standards in the 
Fundamental Review of the Trading Book (FRTB). The horizons in the 
FRTB are specified based on recommendations from consultations with 
the financial industry and its regulators. The horizons in the FRTB 
are therefore considered a reasonable benchmark for defining the 
shock horizons used in the global market shock. The liquidity 
horizons used in the market shock scenarios are not expected to be 
perfectly matched with the FRTB liquidity horizons due to 
granularity differences between the FRTB standards and the global 
market shock template. The FRTB specifies horizons at a more 
granular level, often using different horizons within each asset 
class, whereas the Board uses the same liquidity horizon for all 
market shocks within each asset class. Given these differences, the 
global market shock scenario aims to align with the horizons 
specified by the FRTB by using a weighted average of the FRTB 
horizons within each asset class. The weights are determined using 
aggregate firm exposures. For example, FRTB horizons for equity risk 
factors vary between 10 and 60 business days, and the global market 
shock horizon for this asset class is assumed to be 4 weeks. Because 
the Board imposes an upper bound on global market shock horizons of 
one quarter, there are cases where in which the range of FRTB 
horizons is longer than the global market shock horizon. For 
example, FRTB horizons for corporate credit market shocks vary 
between 60 and 120 business days, but the Board uses a horizon of 3 
months for corporate credit.

5.2.2 Approaches to Market Shock Design

    (a) As an additional component of the severely adverse scenario, 
the Board plans to use a standardized set of market shocks that 
apply to all companies with significant trading activity. The market 
shocks could be based on a single historical episode, hypothetical 
(but plausible) events, or some combination of historical episodes, 
with or without the addition of-hypothetical events (hybrid 
approach). Depending on the type of hypothetical events, a scenario 
based on such events may result in changes in risk factors that were 
not previously observed.
    (b) For the market shock component in the severely adverse 
scenario, the Board plans to use the hybrid approach to develop 
shocks. The hybrid approach allows the Board to maintain certain 
core elements of consistency in market shocks each year while 
providing flexibility to add hypothetical elements based on market 
conditions at the time of the stress tests. In addition, this 
approach will help ensure internal consistency in the scenario 
because of its basis in historical episodes; however, combining the 
historical episode and hypothetical events may require some 
adjustments to ensure mutual consistency of the joint moves. In 
general, the hybrid approach provides considerable flexibility in 
developing scenarios that are relevant each year, and by introducing 
variations in the scenario, the approach will also reduce the 
ability of companies with significant trading activity to modify or 
shift their portfolios to minimize expected losses in the severely 
adverse market shock.
    (c) The Board has considered a number of alternative approaches 
for the design of market shocks. For example, the Board explored an 
option of providing tailored market shocks for each trading company, 
using information on the companies' portfolios gathered through 
ongoing supervision, or other means. By specifically targeting known 
or potential vulnerabilities in a company's trading position, the 
tailored approach would be useful in assessing each company's 
capital adequacy as it relates to the company's idiosyncratic risk. 
However, the Board does not believe this approach to be well-suited 
for the stress tests required by regulation. Consistency and 
comparability are key features of annual supervisory stress tests 
and annual company-run stress tests required in the stress test 
rules. It would be difficult to use the information on the 
companies' portfolios to design a common set of shocks that are 
universally stressful for all covered companies. As a result, this 
approach would be better suited to more customized, tailored stress 
tests that are part of the company's internal capital planning 
process or to other supervisory efforts outside of the stress tests 
conducted under the capital rule and the stress test rules.

5.2.3 Development of the Market Shock

    (a) Consistent with the approach described above, the market 
shock component for the severely adverse scenario will incorporate 
key elements of market developments during historical periods of 
stress, and may include other price and rate movements in certain 
markets that the Board deems to be plausible, though such movements 
may not have been observed historically.
    (b) The Board will identify potential market stress scenarios, 
based on multiple sources of information, including financial 
stability reports, supervisory information, and internal and 
external assessments of market risks and potential flash points. The 
hypothetical elements could originate from major geopolitical, 
economic, or financial market events with potentially significant 
impacts on market risk factors. The severity of these hypothetical 
moves will likely be guided by similar historical events, 
assumptions embedded in the companies' internal stress tests or 
market participants, and other available information.
    (c) Once broad market scenarios are agreed upon, the 
implications for key risk factor groups will be defined. For 
example, a scenario involving the failure of a large, interconnected 
globally active financial institution could begin with a sharp 
increase in credit default swap spreads and a precipitous decline in 
asset prices across multiple markets, as investors become more risk 
averse and market liquidity evaporates. These broad market movements 
will be extrapolated to the granular level for all risk factors by 
examining transmission channels and the historical relationships 
between variables, though in some cases, the movement in particular 
risk factors may be amplified based on theoretical relationships, 
market observations, or the saliency to company trading books. If 
there is a disagreement between the risk factor movements in the 
historical event used in the scenario and the hypothetical event, 
the Board will reconcile the differences by assessing a priori 
expectations based on financial and economic theory and the 
importance of the risk factors to the trading positions of the 
firms.

6. Consistency Between the Macroeconomic Scenarios and the Market Shock

    (a) As discussed earlier, the market shock comprises a set of 
movements in a large number of risk factors that are realized in the 
first quarter of the stress test horizon. Among the risk factors 
specified in the market shock are several variables also specified 
in the macroeconomic scenarios, such as short- and long-maturity 
interest rates on Treasury and corporate debt, the level and 
volatility of U.S. stock prices, and exchange rates.
    (b) The market shock component is an add-on to the macroeconomic 
scenarios that reflects abrupt market disruptions. As a result, the 
market shock component may not always be directionally consistent 
with the macroeconomic scenario. Because the market shock is 
designed, in part, to mimic the effects of a sudden market 
dislocation, while the macroeconomic scenarios are designed to 
provide a description of the evolution of the real economy over two 
or more years,

[[Page 51950]]

assumed economic conditions can move in significantly different 
ways. In effect, the market shock can simulate a market panic, 
during which financial asset prices move rapidly in unexpected 
directions, and the macroeconomic assumptions can simulate the 
severe recession that follows. Indeed, the pattern of a financial 
crisis, characterized by a short period of wild swings in asset 
prices followed by a prolonged period of moribund activity, and a 
subsequent severe recession is familiar and plausible.
    (c) As discussed in section 4.2.3, the Board may feature a 
particularly salient risk in the macroeconomic assumptions for the 
severely adverse scenario, such as a fall in an elevated asset 
price. In such instances, the Board may also seek to reflect same 
risk in the market shock. For example, if the macroeconomic scenario 
were to feature a substantial decline in house prices, it may be 
plausible for the market shock to feature a significant decline in 
market values of any securities that are closely tied to the housing 
sector or residential mortgages.

7. Timeline for Scenario Publication

    (a) The Board will provide a final description of the 
macroeconomic scenarios by no later than February 15. During the 
period immediately preceding the publication of the scenarios, the 
Board will collect and consider information from academics, 
professional forecasters, international organizations, domestic and 
foreign supervisors, and other private-sector analysts that 
regularly conduct stress tests based on U.S. and global economic and 
financial scenarios, including analysts at the firms. In addition, 
the Board will consult with the FDIC and the OCC on setting the 
guides in the scenarios. The Board expects to conduct this process 
each year and disclose the developed scenarios for public comment. 
The Board will update the scenarios, based on the public comments 
and incoming macroeconomic data releases and other information.
    (b) The Board expects to provide a broad overview of the market 
shock component along with the macroeconomic scenarios. The Board 
will publish the market shock templates by no later than March 1 of 
each year, and intends to publish the market shock earlier in the 
stress test and capital plan cycles to allow companies more time to 
conduct their stress tests.

2.1 Soundness in Model Design

    (a) During development, the Federal Reserve
    (i) subjects supervisory models to extensive review of model 
theory and logic and general conceptual soundness;
    (ii) examines and evaluates justifications for modeling 
assumptions;
    (iii) tests models to establish the accuracy and stability of 
the estimates and forecasts that they produce; and
    (iv) invites, evaluates, and responds to substantive public 
input on material model changes.

2.2. Disclosure of Information Related to the Supervisory Stress 
Test

    (a) In general, the Board does not disclose information related 
to the supervisory stress test to covered companies if that 
information is not also publicly disclosed. However, the Board will 
generally provide additional information directly to a covered 
company about such covered company's supervisory stress test 
results, provided that the Board will only do so if it provides the 
same type of information to all other covered companies 
participating in the same stress test cycle.
    (b) The Board has increased the breadth of its public disclosure 
since the inception of the supervisory stress test to include 
comprehensive descriptions of the supervisory stress models, changes 
to those models, and, for each supervisory stress test cycle, more 
information about model changes and key risk drivers, in addition to 
more detail on different components of projected net revenues and 
losses. Increasing public disclosure can help the public understand 
and interpret the results of the supervisory stress test, 
particularly with respect to the condition and capital adequacy of 
participating firms. Providing additional information about the 
supervisory stress test allows the public to make an evaluation of 
the quality of the Board's assessment. This policy also promotes 
consistent and equitable treatment of covered companies by ensuring 
that institutions do not have access to information about the 
supervisory stress test that is not also accessible to other covered 
companies, corresponding to the principle of consistency and 
comparability.

3.1. Structural Independence

* * * * *
    (b) In addition, the Model Validation Council, a council of 
external academic experts, provides independent advice on the 
Federal Reserve's process to assess models used in the supervisory 
stress test. In biannual meetings with Federal Reserve officials, 
members of the council discuss selective supervisory models, after 
being provided with detailed model documentation for those models. 
The documentation and discussions enable the council to assess the 
effectiveness of the models used in the supervisory stress tests and 
of the overarching model validation program.

3.2. Technical Competence of Validation Staff

* * * * *
    (c) The model validation program covers three main areas of 
validation:
    (1) Conceptual soundness;
    (2) ongoing monitoring; and
    (3) outcomes analysis.

    Validation staff evaluates all aspects of model development, 
implementation, and use, including but not limited to theory, 
design, methodology, input data, testing, performance, documentation 
standards, implementation controls (including access and change 
controls), and code verification.

    By order of the Board of Governors of the Federal Reserve 
System.
Benjamin W. McDonough,
Deputy Secretary of the Board.
