Appendix A to Part 252 - Policy Statement on the Scenario Design Framework for Stress Testing
12:4.0.1.1.20.19.3.1.11 : Appendix A
Appendix A to Part 252 - Policy Statement on the Scenario Design
Framework for Stress Testing 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) 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). 1 In addition, under the stress test rules, certain
firms are also subject to company-run stress test requirements. 2
The Board will provide for at least two different sets of
conditions (each set, a scenario), including baseline and severely
adverse scenarios for both supervisory and company-run stress tests
(macroeconomic scenarios). 3
1 12 U.S.C. 5365(i)(1); 12 CFR part 252, subpart E.
2 12 U.S.C. 5365(i)(2); 12 CFR part 252, subparts B and F.
3 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.
(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 scenario by no later than March 1 of each year. 4 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).
4 Id.
(c) In addition, § 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. 5
5 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 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 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). 6
6 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 types of variables
that the Board expects to include in the macroeconomic scenarios
and the market shock component of the stress test scenarios
applicable to companies with significant trading activity. Section
4 describes the Board's approach for developing the macroeconomic
scenarios, and section 5 describes the approach for the market
shocks. Section 6 describes the relationship between the
macroeconomic scenario and the market shock components. Section 7
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 a minimum of two different scenarios,
including baseline and severely adverse conditions, for use in
stress tests required in the stress test rules. 7 In general, the
Board anticipates that it will not issue additional scenarios.
Specific circumstances or vulnerabilities that in any given year
the Board determines require particular vigilance to ensure the
resilience of the banking sector will be captured in the severely
adverse scenario. A greater number of scenarios could be needed in
some years - for example, because the Board identifies a large
number of unrelated and uncorrelated but nonetheless significant
risks.
7 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 also 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 on all of 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 broad
description of the market shock components.
3.1 Macroeconomic Scenarios
(a) The macroeconomic scenarios will consist of the future paths
of a set of economic and financial variables. 8 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:
8 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.
(i) 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;
(ii) 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
(iii) 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:
(i) Percent change in real GDP;
(ii) Percent change in the Consumer Price Index or local
equivalent; and
(iii) The U.S./foreign currency exchange rate. 9
9 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. 10 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 a number of
ways, both in their design and application. For instance, market
shocks that might typically be observed over an extended period
(e.g., 6 months) are assumed to be an instantaneous event
which immediately affects the market value of the companies'
trading assets and liabilities. 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
private equity positions).
10 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 large and noncomplex 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 equities, credit, interest rates, foreign
exchange rates, and commodities. Examples of risk factors include,
but are not limited to:
(i) Equity indices of all developed markets, and of developing
and emerging market nations to which companies with significant
trading activity may have exposure, along with term structures of
implied volatilities;
(ii) Cross-currency FX rates of all major and many minor
currencies, along term structures of implied volatilities;
(iii) Term structures of government rates (e.g., U.S.
Treasuries), interbank rates (e.g., swap rates) and other key rates
(e.g., commercial paper) for all developed markets and for
developing and emerging market nations to which companies may have
exposure;
(iv) Term structures of implied volatilities that are key inputs
to the pricing of interest rate derivatives;
(v) Term structures of futures prices for energy products
including crude oil (differentiated by country of origin), natural
gas, and power;
(vi) Term structures of futures prices for metals and
agricultural commodities;
(vii) “Value-drivers” (credit spreads or instrument prices
themselves) 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; and
(viii) Shocks to the values of private equity positions.
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)
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 FOMC'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
a large number of 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. 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.
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. The most
common features of recessions, however, 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 National Bureau of Economic
Research reviews to inform its recession dates. 11 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. 12
11 More recently, a monthly measure of GDP has been added to the
list of indicators.
12 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 3/4 percent and the unemployment rate moving up
a total of about 4 percentage points.
(c) 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.
(d) The Board will specify the paths of most other macroeconomic
variables based on the paths of unemployment, income, house prices,
and activity. Some of these other variables, however, have taken
wildly divergent paths in previous recessions (e.g., foreign GDP),
requiring the Board to use its informed judgment in selecting
appropriate paths for these variables. In general, the path for
these other variables 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).
(e) 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-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 the Unemployment Rate Under the Severely Adverse
Scenario
(a) 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. 13 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 the most recent
three 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.
13 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.
(b) This methodology is intended to generate scenarios that
feature stressful outcomes but do not induce greater procyclicality
in the financial system and macroeconomy. 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 and 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 - the unemployment
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 and a severely
adverse scenario that is relatively less intense. Historically, a 3
to 5 percentage point increase in unemployment rate is reflective
of stressful conditions. As illustrated in Table 1, over the last
half-century, the U.S. economy has experienced four severe post-war
recessions. In all four of these recessions, the unemployment rate
increased 3 to 5 percentage points and in the three most recent of
these recessions, the unemployment rate reached a level between 9
percent and 11 percent.
(c) Under this method, if the initial unemployment rate was 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 was 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.
(d) The Board believes that the typical increase in the
unemployment rate in the severely adverse scenario will be about 4
percentage points. However, the Board will calibrate the increase
in unemployment based on its views of the status of cyclical
systemic risk. The Board intends to set the unemployment rate at
the higher end of the range if the Board believes that cyclical
systemic risks are high (as it would be after a sustained long
expansion), and to the lower end of the range if cyclical systemic
risks are low (as it would be in the earlier stages of a recovery).
This may result in a scenario that is slightly more intense than
normal if the Board believed that cyclical systemic risks were
increasing in a period of robust expansion. 14 Conversely, it will
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 an expansion. Indeed, the
Board expects that, in general, it will adopt a change in the
unemployment rate of less than 4 percentage points when 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 either already realized - or are in the process of being
realized - and thus removed from banks' balance sheets. 15 However,
even at the lower end of the range of unemployment-rate increases,
the scenario will still feature an increase in the unemployment
rate similar to what has been seen in about half of the severe
recessions of the last 50 years.
14 Note, however, that the severity of the scenario would not
exceed 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.
15 Evidence of a strengthening labor market could include 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.
(e) 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 the most recent three 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 that these risks are also easily
obscured by the buoyant environment.
(f) 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). In addition, the Board -
in light of impending shocks to the economy and financial system -
will 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
confidence in financial institutions.
(g) While the approach to specifying the severely adverse
scenario is designed to avoid adding sources of procyclicality to
the financial system, it is not designed to explicitly offset any
existing procyclical tendencies in the financial system. The
purpose of the stress test scenarios is to make sure that the
companies are properly capitalized to withstand severe economic and
financial conditions, not to serve as an explicit countercyclical
offset to the financial system.
(h) In developing the approach to the unemployment rate, the
Board also considered a method that would increase the unemployment
rate to some fairly elevated fixed level over the course of 6 to 8
quarters. This would result in scenarios being more severe in
robust expansions (when the unemployment rate is low) and less
severe in the early stages of a recovery (when the unemployment
rate is high) and so would not result in pro-cyclicality. Depending
on the initial level of the unemployment rate, this approach could
lead to only a very modest increase in the unemployment rate - or
even a decline. As a result, this approach - while not procyclical
- could result in scenarios not featuring stressful macroeconomic
outcomes.
4.2.3 Setting the Other Variables in the Severely Adverse Scenario
(a) Generally, all other variables in the severely adverse
scenario will be specified to be consistent with the increase in
the unemployment rate. The approach for specifying the paths of
these variables in the scenario will be a combination 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, and (3) evaluation of
these and other factors.
(b) 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). For some other variables, specifying
their paths will require a case-by-case consideration.
(c) Declining house prices, which are an important source of
stress to a company's balance sheet, are not a steadfast feature of
recessions, and the historical relationship of 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. 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, disposable
income (DPI). The Board believes that the typical decline in the
HPI-DPI ratio will be at a minimum 25 percent from its starting
value, or enough to bring the ratio down to its Great Recession
trough. As illustrated in Table 2, housing recessions have on
average featured HPI-DPI ratio declines of about 25 percent and the
HPI-DPI ratio fell to its Great Recession trough. 16
16 The house-price retrenchments that occurred over the periods
1980-1985, 1989-1996, 2006-2011 (as detailed in Table 2) 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, although, 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 2 are
calculated based on nominal HPI and HPI-DPI ratios indexed to 100
in 2000:Q1.
(d) 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 an invariable feature of the international
economy. 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.
4.2.4 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 will feature minimally in the scenario if
the Board were only to use approaches that looked to past
recessions or relied on historical relationships between
variables.
(b) There are some important instances when 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) Detecting risks that have the potential to weaken the
banking sector is particularly difficult when economic conditions
are buoyant, as a boom can obscure the weaknesses present in the
system. In sustained robust expansions, therefore, the selection of
salient risks to augment the scenario will err on the side of
including risks of uncertain significance.
(e) 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. 17
17 The means of effecting an adjustment to the severely adverse
scenario to address salient systemic risks differs from the means
used to adjust the unemployment rate. 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 are
similar to how these variables have moved historically. 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,
albeit 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 an
instantaneous “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
By definition, market shocks are large, previously unanticipated
moves in asset prices and rates. Because asset prices should,
broadly speaking, reflect consensus opinions about the future
evolution of the economy, large 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 extreme
moves in observable, broad market indicators and risk factors or
directly as large changes to the mark-to-market values of financial
instruments. These moves can be specified either in relative terms
or absolute terms. Supplying values of risk factors after a “shock”
is roughly equivalent to the macroeconomic scenarios, which supply
values for a set of economic and financial variables; however,
trading stress testing differs from macroeconomic stress testing in
several critical ways.
(b) In the past, the Board used one of two approaches to specify
market shocks. During SCAP and CCAR in 2011, the Board used a very
general approach to market shocks and required companies to stress
their trading positions using changes in market prices and rates
experienced during the second half of 2008, without specifying risk
factor shocks. This broad guidance resulted in inconsistency across
companies both in terms of the severity and the application of
shocks. In certain areas, companies were permitted to use their own
experience during the second half of 2008 to define shocks. This
resulted in significant variation in shock severity across
companies.
(c) To enhance the consistency and comparability in market
shocks for the stress tests in 2012 and 2013, the Board provided to
each trading company more than 35,000 specific risk factor shocks,
primarily based on market moves in the second half of 2008. While
the number of risk factors used in companies' pricing and
stress-testing models still typically exceed that provided in the
Board's scenarios, the greater specificity resulted in more
consistency in the scenario across companies. The benefit of the
comprehensiveness of risk factor 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.
(d) 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 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.
(e) The instantaneous nature of market shocks and the immediate
recognition of mark-to-market losses add another element to the
design of market shocks, and to determining the appropriate
severity of shocks. For instance, in previous stress tests, the
Board assumed that market moves that occurred over the six-month
period in late 2008 would occur instantaneously. 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.
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,
multiple historical periods, hypothetical (but plausible) events,
or some combination of historical episodes and 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. In the supervisory scenarios for
2012 and 2013, the shocks were largely based on relative moves in
asset prices and rates during the second half of 2008, but also
included some additional considerations to factor in the widening
of spreads for European sovereigns and financial companies based on
actual observation during the latter part of 2011.
(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 small
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' portfolio 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 the second half of 2008,
but will also incorporate observations from other periods or price
and rate movements in certain markets that the Board deems to be
plausible, though such movements may not have been observed
historically. Over time, the Board also expects to rely less on
market events of the second half of 2008 and more on hypothetical
events or other historical episodes to develop the market
shock.
(b) The developments in the credit markets during the second
half of 2008 were unprecedented, providing a reasonable basis for
market shocks in the severely adverse scenario. During this period,
key risk factors in virtually all asset classes experienced
extremely large shocks; the collective breadth and intensity of the
moves have no parallels in modern financial history and, on that
basis, it seems likely that this episode will continue to be the
most relevant historical scenario, although experience during other
historical episodes may also guide the severity of the market shock
component of the severely adverse scenario. Moreover, the risk
factor moves during this episode are directly consistent with the
“recession” approach that underlies the macroeconomic assumptions.
However, market shocks based only on historical events could become
stale and less relevant over time as the company's positions
change, particularly if more salient features are not added each
year.
(c) While the market shocks based on the second half of 2008 are
of unparalleled magnitude, the shocks may become less relevant over
time as the companies' trading positions change. In addition, more
recent events could highlight the companies' vulnerability to
certain market events. For example, in 2011, Eurozone credit
spreads in the sovereign and financial sectors surpassed those
observed during the second half of 2008, necessitating the
modification of the severely adverse market shock in 2012 and 2013
to reflect a salient source of stress to trading positions. As a
result, it is important to incorporate both historical and
hypothetical outcomes into market shocks for the severely adverse
scenario. For the time being, the development of market shocks in
the severely adverse scenario will begin with the risk factor
movements in a particular historical period, such as the second
half of 2008. The Board will then consider hypothetical but
plausible outcomes, based on financial stability reports,
supervisory information, and internal and external assessments of
market risks and potential flash points. The hypothetical outcomes
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.
(d) Once broad market scenarios are agreed upon, specific risk
factor groups will be targeted as the source of the trading stress.
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 covered companies.
6. Consistency Between the Macroeconomic Scenarios and the Market
Shock
(a) As discussed earlier, the market shock comprises a set of
movements in a very large number of risk factors that are realized
instantaneously. 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 is applied to a subset of companies, with no assumed
effect on other aspects of the stress tests such as balances,
revenues, or other losses. As a result, the market shock component
may not be always 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, 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 4.2.4, 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 the
same risk in one of the market shocks. For example, if the
macroeconomic scenario were to feature a substantial decline in
house prices, it may seem plausible for the market shock to also
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 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 covered companies.
In addition, the Board will consult with the FDIC and the OCC on
the salient risks to be considered in the scenarios. The Board
expects to conduct this process in October and November of each
year and to update the scenarios, based on incoming macroeconomic
data releases and other information, through the end of
January.
(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.
