This financial crisis was due to opacity and lack
of transparency in financial markets and regula-
tors who were asleep at the wheel. But now the
administration and the regulators have decided
to add liberally to the fog of opacity. Why call
them stress tests? Fudge tests would be a
truer description. Nouriel Roubini (2009)
Stress testing is a risk management tool nowadays regularly used by national
banking and financial regulators to assess the capacity of the largest bank holding com-
panies ability to weather financial and economic market turmoil and find out if they pos-
sess sufficient capital buffers to continue operations throughout such adverse periods.
Such testing also tries to see if the BHCs have robust, forward-looking capital-planning
processes that account for their unique risks. (Board of Governors of the Federal
Reserve System, 2014)
Capital adequacy ratios as a tool used in prudential bank regulation have been
used prior to the adoption of the first Basel Accords in 1988. Conversely, stress-testing
has a shorter history and historically was predominantly used in-house within banking
and financial institution as one of diverse array of risk management tools. In 2009, the
stress-testing techniques were introduced to system-wide risk management toolkit by
financial regulators in the US and EU. (Wall, 2014)
Stress Testing in Europe and the US: Overview
National bank supervision agencies expect banks to hold sufficient capital to cov-
er losses should adverse economic conditions occur. In this area, stress testing has be-
come one of the most important tools for bank supervisors to achieve that goal.
Greenlaw et al. (2012) distinguish two types of stress tests: microprudential and
macroprudential. Microprudential stress tests focus on preventing bank failures that re-
sult after bank equity meltdown. Here, bank capital is viewed as a buffer against losses
that takes hit before the deposit insurance agency gets hold of situation. Stress testing
procedures focus on Basel capital ratios, and stability and liquidity crises are motivating

events. At the same time, macroprudential stress tests view the banking system as inte-
grated unit where entire balance sheet capacity of BHCs supports the normal function-
ing of the wider economy. Per Greenlaw et al. (2012), the central goal of the testing is to
prevent or mitigate consequences of bank runs on system critical institutions by whole-
sale creditors, which might lead to loan volume contraction and damage to the broader
economy. According to the authors, results should include specific money amounts of
capital that should be raised rather than focus on mere satisfaction of capital ratios. The
summary of differences microprudential and macroprudential stress testing techniques
can be found in Table 2 in Additional Tables and Illustrations.
Another way that stress-testing designs may differ one from the other is their ob-
jectives, i.e. whether their results are intended for internal or external use. Stress testing
that is performed for internal decision making purposes are used to reflect the risk man-
agement culture of the organization. On the other hand, the results of the stress testing
exercise that are meant to be used externally should be well understood by the target
audience, i.e. regulators, authorities, investors and consumers. (Drehmann, 2008)
European and American regulators are pursuing similar goals when they conduct
stress testing of major BHCs, namely understanding their capacities to absorb financial
losses and through these preventing financial disturbances from negatively affecting ac-
tivities of other actors in a broader economy. At the same time, their approaches to the
stress testing process, design of such testing exercises and subsequently their focus
differ in each case.
Design of Stress Testing in the United States
In 2009, when the first stress tests were conducted in the US, the Fed had not
adopted Basel II as a framework in bank supervision. Therefore, between 2009 and
2014, the Fed was using a combination of Basel I with its amendments and a leverage
ratio with gross total assets in the denominator. Current stress testing procedure was
adopted due to the requirements of the Basel III which was adopted by the US bank su-
pervisor for the implementation in 2014 (Wall, 2014).
Nowadays, the US Federal Reserve is committed to using two measures to as-
sess capital adequacy and the degree of financial stability of the BHCs under its super-
vision. The Dodd-Frank Act introduced annual Dodd-Frank Act Stress Testing which
Ivan Dyachok, 3352663

was meant to restore confidence in the US banking system in 2009 and is the scenario-
based stress testing exercise in the US. (Board of Governors of the Federal Reserve
System, 2014)
The scenarios are divided into base, adverse and severely adverse depend-
ing on the underlying projections. The base scenario aligns with general economic
forecasts for the US economic development throughout the testing period; adverse and
severely adverse scenarios are completely hypothetical and are developed purely to
test the rigidity of the banking system to withstand economic shocks (Board of
Governors of the Federal Reserve System, 2014).
The scenarios start in the 4th quarter of 2014 and extend to the 4th quarter of 2017
(i.e. they encompass 12 quarters in total). The set of 28 variables has stayed unchanged
compared to the last year stress-testing describing the economic conditions in the US
and abroad. The internal variables are divided as follows: six measures of economic ac-
tivity and prices, four aggregate measures of asset prices or financial conditions, and six
measures of interest rates. The international variables are grouped by countries or coun-
try blocs (i.e. four such groups) and describe three variables each: real GDP growth,
CPI change, and USD/local currency exchange rate. (Board of Governors of the Federal
Reserve System, 2014)
DFAST, a forward-looking component of the assessment procedures, is conduct-
ed by the Fed and financial companies under review. DFAST is used to assess if the
BHCs have enough capital to absorb losses and continue operations without disruptions
during adverse economic conditions while using historical capital actions of each BHC
(i.e. dividends or stock buy-backs). Complimentary to DFAST, Comprehensive Capital
Analysis and Review, an annual exercise, is carried out by the US Fed. According to the
methodology, the Fed analyses capital adequacy ratios, capital assessment processes
implemented by BHCs while taking into account capital action plans proposed by the
BHCs. As of 2014 reporting period, BHCs active in the US with assets less than
USD10bn were not subject to CCAR and DFAST procedures. (Board of Governors of
the Federal Reserve System, 2014). Based on the DFAST and CCAR results the Fed
can demand amending the capital action plans proposed by the bank or even turn them
down altogether. (Ernst & Young LLP, 2015)
Ivan Dyachok, 3352663

31 BHCs participated in 2015 DFAST and CCAR (those BHC with assets be-
tween USD10bn and USD50bn were required to conduct DFAST only). Deutsche Bank
Trust Corporation is the only new BHC participating in CCAR/DFAST 2015 compared to
2014 stress-testing publication period. Nine participants with aggregate assets exceed-
ing USD50bn each were tested as members of the Large Institution Supervision Coordi-
nating Committee portfolio. These BHCs are Bank of America, BNY Mellon, Citigroup
(Citi), Deutsche Bank Trust Corporation, Goldman Sachs, JPMorgan Chase, Morgan
Stanley, State Street and Wells Fargo. The Fed has heightened expectations for capital
planning processes at these institutions relative to other CCAR participants due to their
size, complexity, and role in the wider economy. (Ernst & Young LLP, 2015) Such ex-
pectations translate into requirement to run company-designed stress-testing twice a
year. (De Ghenghi & Rohrkemper, 2015). For more information on how the DFAST
stress-testing approach differs between large and mid-size BHCs, please, refer to Table
6 in Additional Tables and Illustrations.
Design of Stress Testing in the European Union
The results for the latest Euro-zone stress-testing were published in October
2014. During this stress testing exercise, balance sheets of 130 BHCs across 18 coun-
tries and Lithuania1 with combined assets amounting to 85% of Euro-zones banking in-
dustry aggregate assets were scrutinized by the European Central Bank while national
regulators assisted in the process. At the same time, European Banking Association ran
tests on 123 banks in 28 countries across the EU. Parallel to stress-testing, Asset Quali-
ty Review took place to determine the value of the assets on the balance sheets, and it
was conducted by ECB and the national regulators. (Steinhauser, 2014). Within the
AQR, ECB examined 800 portfolios which represented ca. 57% of the banks risk-
weighted assets. This exercise included analysis of 119,000 borrowers and 170,000
pieces of collateral (Quinn, 2014).
As Steinhauser (2014) describes it, the EU stress-testing and AQR were de-
signed to detect banking institutions which risk weighted assets would fall below 8%
threshold should the economy develop as expected (during the latest stress testing ex-
ercise: until 2016). The crisis scenario envisaged a two-year recession combined with a

market panic as experienced in the US after the collapse of Lehman Brothers. In this
case, the BHCs were to maintain a capital buffer of at least 5.5%.
Should a bank fail the test, within two weeks, its management had to come up
with a plan to increase BHCs capital buffer. The shareholders are incentivized to be one
of the primary sources of new capital; another option is selling excessive or risky assets
on the market. In case a BHC fails either AQR or stress tests baseline scenario, its
management has six months to implement the proposed plan. Those that fail only crisis
scenario are given nine months to increase the capital ratio. In severe cases, i.e. a capi-
tal hole is found on Systemically Important Financial Institutions balance sheet, a capital
increase plan is to be developed within one week. If the bank fails to increase its capital
ratio, the government or national agency has to step in, but only after the current share-
holders take a haircut. (Steinhauser, 2014)
Outcomes and Implications of the Latest Stress Testing
Stress-testing exercise in the USA was first conducted in 2009 and since then the
exercise was carried out annually, except for 2010 when it did not take place. The sum-
mary of the US stress tests in 2009-2013 is shown in Table 3 in Additional Tables and
Illustrations.
Latest DFAST and CCAR results were published on March 5, 2015, and March
11, 2015, respectively. The summary of what the scopes of 2015 DFAST and CCAR ex-
ercises is presented in Table 1 below:

scenarios nario incl. planned actions, for se-verely adverse and adverse scenarios
Of the 31 banks that underwent the 2015 DFAST and CCAR testing, all institu-
tions successfully passed the scrutiny. The results of both simulation-based DFAST with
historical capital actions and the forward-looking CCAR showed that the lowest Tier 1
Common capital ratios were at the BHCs that have large investment banking and trading
activities (BHCs IB & Retail and Custodian on Figure 1) as the leverage ratios ap-
pears to be a binding constraint for these institutions (Ryan, Alix, Gilbert, & Meyer,
2015). At the same time, Ryan et al. (2015) notes that 2015 DFAST results indicated
that on average there is more Tier 1 Capital in the banking system now than it was be-
fore the stress-tests were introduced: 8.2% under the severely adverse scenario, which
is higher than the same banks pre-stress T1C average of 5.5% at the beginning of
2009.
Over the DFAST simulation period, total losses at the 31 BHCs under the severe-
ly adverse scenario were projected to reach USD490bn. At the same time, projected net
revenue before provisions for loan and lease losses (pre-provision net revenue, PPNR)
was projected to reach USD310bn, and net losses before taxes USD222bn. (Board of
Governors of the Federal Reserve System, 2015)

Figure 1. CCAR2 2015 results for the major BHCs in the US (Deloitte Center for
Regulatory Strategies, 2015)
Ryan et al. (2015) elaborates further on the outcomes of the recent stress testing
exercise in the US noting that total loan losses declined for the third time (to 6.1% down
from 6.9% in 2014 and 7.5% in 2013) which can be attributed to improved underwriting
standards as well as improving situation with the legacy credit portfolios. Additionally,
the banks under review have prepared to the possible Feds rate increase with only four
institutions not showing pre-tax profit over the nine quarters simulation period. Further
on, the authors add that the 2016 DFAST and CCAR will most likely be tougher for the
BHCs under review with Global Systemically Important Bank capital surcharge being ul-
timately factored into the stress testing process. Such change is driven by the criticism
that the Fed received for being too predictable.
The most recent European stress testing for 2013 published in October 2014 in-
dicated a cumulative capital shortfall of EUR24.6bn (or ca. USD31.2bn). The previous
stress-testing exercises in the Euro-area brought criticism for their lack of rigorousness
and failed to notice holes in capital structure of several banks. This one, however, was

promised to bring real prudential supervision to the European banking industry. ECB
Executive Board member Joerg Asmussen also admitted that this stress-testing was the
last chance for the ECB to restore confidence in the industry and the ECB itself as its
supervisor. The ECB President Mario Draghi vowed to give failing marks to the BHCs
which would not stand the test. (Riecher & Black, 2013)
Since the test results showed capital deficit as of year beginning, most of it had
been already covered by October, and only EUR9.5bn was still outstanding. Figure 2
below shows how the 2014 results compare to the previously held stress tests in the EU.
The rising number of banks that failed the stress testing is attributed to the growing
number of institutions under scrutiny, on one hand, and to the growing rigorousness of
the test itself, on the other hand. This was done to show different stakeholders that the
financial stability of the European banking system was improving after the first stress
tests failed to take note of the upcoming difficulties at some of the institutions
(Steinhauser, Enrich, & Colchester, 2014). More on this issue will be presented in chap-
ter Criticism below.
Figure 2. Overview3 of EU Stress Testing Outcomes in 2010-2014 (Steinhauser,
Enrich, & Colchester, 2014)
Of the 25 failed banks, 12 institutions increased their capital buffers by the re-
ports publication date. Most of the capital (EUR25.9bn or ca. 73%) increase came in
form of new equity, according to data from Morgan Stanley (Steinhauser, Enrich, &
Colchester, 2014):

The distribution of BHCs that failed the test aligns with the countries that were
most affected by the aftermaths of sovereign debt crisis in the EU, i.e. most of such insti-
tutions were in Italy, Greece, Spain, Portugal, and Ireland, although presumably stronger
northern countries such as Ireland, Belgium, Germany, and Austria also saw some of
the failed banks. Given this, most of the capital raising took place in southern EU:

Among the 13 banks that had not increased their capital buffer by the stress-
testing reports publication date, the biggest problems were found with Italian, Greek and
Portuguese banks. Among the BHCs with uncovered holes in their capital structure was
Banca Monte dei Paschi which is Italys third-largest and has to come up with EUR2.1bn
of capital representing ca. 63.7% of all capital shortfall by the Italian lender as of Octo-
ber 2014. As for the Greek banks, Eurobank and National Bank of Greece although
failed, had no or practically no shortfalls taking into account capital already raised, the
ECB said. Dexia SA, which needed government bailout5 after the 2011 stress testing in-
dicated it had enough capital, is being wound down according to the plan approved by
the EU authorities in 2012 (Leighton-Jones & Hearon, 2014). For more details on the
capital needs exposed by the stress-testing outcome, please refer to Figure 5 and Fig-
ure 6 below:
Figure 5. Breakdown of individual bank capital shortfall as of Oct. 2014 (Karaian,
2014)
5 Under the restructuring plan, the BHC received EUR90bn of government guarantees from the
French, Luxemburg, and Belgian governments, the Belgian and French governments provided EUR6bn of public bailout funds; later in 2011 Belfius received another EUR4bn financial assistance from the Belgian government. It was split into two separate institutions of which Belgium-based resumed its banking opera-tions under the new name Belfius, and the Netherlands-based part of the BHC was set up as a bad bank (Treanor, 2011)

Whether the latest EU stress-testing was a success and brought back trust to the
banking industry in the Euro-zone, remains disputable. It should be noted, however that
the volumes of bank lending growth rates in the Euro-zone increased after the publica-
tion of the stress-testing results as indicated in Figure 7:

At the same moment, this growth may due to be economic stabilization of the
GDP growth in the Euro-zone: according to the ECBs data, after the 1st quarter 2013
the risk of W-shaped recession in the Euro-zone diminished as the growth rate picked
up from the anemic rates around 0% in 2012, as depicted in Figure 8. Given lending
volumes react to GDP growth rates with some time lag, such GDP dynamics could sig-
nificantly contribute to general situation in the banking sector.

Criticism
The observers, industry experts, and analysts have been vocal about the short-
comings of the stress-testing exercises both in the US and the EU since the financial
check-ups were introduced in 2009, with most criticism addressing the EU stress tests
due to their unreliable results in the past. (Hardy & Hesse, 2013)
Kashyan et al. (2012) argue that stress testing exercises both in the US and the
EU fail to determine the rigidity of the whole banking system to weather sudden eco-
nomic and financial downturns as they concentrate on balance sheets of individual
banks in isolation while ignoring potential spillover effects within the whole system. The
authors go ahead to note, that banking regulators during stress testing concentrate on
the common capital levels while they ignore the main source of balance sheet financing
being wholesale bank financing. Compared to common equity, wholesale financing is
more volatile and can be withdrawn by the creditors should they sense increasing mar-
ket risks forcing banking institutions to fire sell their assets to deleverage balance

sheets, and consequently leading to domino effect as asset prices decline which affects
all market players.
Goldstein (2014) suggests that the ECB and EBA scrap the risk-weighted assets
as a base measure used in stress testing since it proved to be a less predictable meas-
ure of bank failure in the future. Unweighted leverage ratios are already used in the US
and the UK bank stress testing and have proved their usefulness. Furthermore, before
the 2007-2009 financial crisis, risk weighted measures indicated that banks were well-
capitalized in contrast to the unweighted measures. However, at the same time, Gold-
stein stresses that EU regulators should not completely rely on the US approach to
stress testing and the requirements that the Fed has developed for the BHCs under its
supervision: the EU banking system is more concentrated than the US one, and there-
fore European banks need to hold higher capital cushions compared to their US coun-
terparts.
Some observers have also criticized accounting tricks that the BHCs employ to
hide the magnitude of their risk exposure. There is a significant room for balance sheet
optimization according to Alberto Gallo, head of European macro credits at Royal Bank
of Scotland, and the bigger the BHC the better it can conceal risky assets (Thompson
& Ross, 2014). Alberto Gallo adds further: There is almost an inverse relationship be-
tween the size of banks and how much regulatory risk they declare some large in-
vestment banks have optimized their models over time to show their assets are less
risky. For example, Deutsche Bank in its 2012 annual financial report has managed to
present EUR55.605 trillion of derivative exposure7 via first displaying net values on as-
sets side amounting to EUR776.7bn and on liabilities side to EUR756.4bn, which in the
end netted each other to the amount of EUR20.3bn. (Durden, At $72.8 Trillion,
Presenting The Bank With The Biggest Derivative Exposure In The World (Hint: Not
JPMorgan), 2013)
Another point of criticism is the how the results of stress testing are used by the
BHCs shareholders. Should a given bank pass the test, such result effectively allows
distribution of dividends regardless of how much better than the threshold were the re-
7 The aggregate deposits of the Deutsche Bank are ca. 100 times smaller, and this amount is ca.
20 times larger than the entire 2012 GDP of Germany, as Germany Trade & Invest indicates (Business Briefing: Germany, 2014)

sults. For example, in 2007 the US supervisors allowed distribution of dividends amount-
ing to USD80bn by 19 banks which in 2009 were subject to Supervisory Capital As-
sessment Program. This amounted roughly to half of the total public funds injected in
these institutions in the form of recapitalization later. (Greenlaw, Kashyap, Schoenholz,
& Shin, 2012)
Last but not the least important point of criticism is the stress-testing scenarios
which in some respects envisage mild or short-living recessions. For example, the ECB
did not include deflation in its set of scenarios even though the Euro-zone was about to
be in deflation according to statistical data (Durden, 2014). The Feds 2014 DFAST sce-
narios envisaged relatively swift return to economic growth as well as Dow-Jones Indus-
trial Index returning to record high levels within 9 quarters (Durden, 2015).
Conclusions
In this paper, I tried to outline the way stress testing as regulatory risk manage-
ment and prudential tool has been implemented in the US and the Euro-zone. Although,
both approaches have much in common, there are important differences between the
two. There is also a lot to improve in both stress-testing methodologies, if the regulators
are determined to make stress-testing an effective tool in a macroprudential supervisory
arsenal. Currently, due to various reasons most improvements are to be developed and
implemented by the ECB, the EBA, and the newly set-up Single Supervisory Mechanism
and European Systemic Risk Board which together will coordinate and conduct banking
stress testing in the EU.
The evolution of the stress testing throughout the past years revealed several
weak points that should be addressed in the near future. Some of the major points have
been covered in the section Criticism of this paper. At the same time, as forward-looking
prudential exercise, the future generations of the stress testing should seek to address
not only issues that ignited the 2007-2009 financial crisis, but also the challenges that
will shape the development of the banking industry in the future.
First off, the regulators have to re-assess the required minimum capital to be
maintained by the banking institutions. As Goldstein (2014) suggests, the required capi-
talization levels everywhere are too low. He further refers to the broad support by the
Ivan Dyachok, 3352663
21
leading financial academics who propose that the new level of leverage ratios should be
15% which is substantially higher than the 3% proposed by the Basel lll; achieving such
a target would generate substantial social benefits with minimal social cost.
In the midterm, the bank regulators should re-focus their attention on liquidity and
funding stress testing, especially in the context of the phasing in of detailed common re-
porting templates on maturity mismatches, cost of funding, and asset encumbrance
(Hardy & Hesse, 2013). Future stress-testing scenarios should also incorporate more
long-term factors and generate lessons that relate more to structural issues. The worlds
financial system faces a prolonged period of low interest rates, possibly low growth, in-
creased regulatory burdens under Basel III and in Europe also Capital Requirement Di-
rective IV, demographic change as well as structural changes in employment patterns
(i.e. higher share of part-time, temporary and freelance workers) in developed countries.
These developments will put pressure on profitability, the supply of savings, industry
competition, etc. Therefore, the stress test scenarios need to encompass a longer time
horizon, incorporate structural shifts (e.g. ongoing deleveraging and changes of bank
funding profiles) affecting the balance sheet and income. (Hardy & Hesse, 2013)

Schoenholz, & Shin, 2012)
Item of comparison Microprudential Macroprudential
Purpose The goal is to value bank assets correctly and determine that adequate
loss-bearing capacity is in place to protect taxpayers from having to bail
out insured deposits
The goal is to limit the likelihood and costs of aggregate fire sales, credit
crunches and defaults
Scope Analyze one bank at a time, or use data from multiple banks to over-
come imperfect information about the value of individual bank assets
The test examines the entire financial system. Any entity that contrib-
utes to fire sales, whose default has follow-on effects, or which can
exacerbate a credit crunch should be included
Liability Considerations Count the amount of insured deposits and the amount of junior debt
and equity. The required loss absorbency is calculated as a ratio rela-
tive to asset risk.
Because a run can lead to a credit crunch or fire sale, the scale of
wholesale funding that is run-prone is paramount. Capital adequacy
depends on the health of the overall financial system
Asset Considerations Credit risk of different assets determines enterprise risk, so loss absor-
bency of liabilities is tied to asset composition. A capital ratio therefore
naturally emerges as a basis for supervision
Asset liquidity is critical, because illiquid assets can contribute to fire
sales. Asset risk depends both on default risk and fire sale risk
Output Develop guidance about whether to close a bank and when to sell its
assets to maximize taxpayer recovery
The test indicates whether the financial system is vulnerable to delever-
aging that might amplify adverse shocks

Pre-Provision Net Revenue (PPNR) Model:
- Granular estimation approach - Less granular top of the house approach
- Use internal revenue and expense data to estimate business lines revenues and ex-penses
- Project PPNR based on three main components (net interest income, noninterest in-come and noninterest expense)
- Identify specific drivers of revenue and expenses and analyze how supervisory scenar-ios affect those drivers
- Can project at an aggregate, company-wide level, and may be based on industry expe-rience
