DFAST(Dodd-Frank Act Stress Tests)

CCAR(Comprehensive Capital Analysis and Review)

“DFAST 10-50” $10 Billion to $50 Billion in

Assets One DFAST per year

“DFAST 50” $50+ Billion in Assets Two DFASTs per year

Fed uses a standardized set of capital action assumptions

For 31 (33) US Banks ($50+ Billion), the Fed: Uses a bank’s planned capital

actions Assesses whether a bank would be

capable of meeting supervisory expectations for minimum capital ratios

While the supervisory DFAST and CCAR quantitative assessment incorporate the same projections of pre-tax net income, the primary difference is the capital action assumptions that are combined with these projections to estimate a Large BHC’s post-stress capital levels and ratios..

Stress Testing at First National Bank

• Lessons Learned:• Good Modeling Requires Good Data • Data Warehousing• Resources – Technical and Human• Time Management

• Issues:• Data • Data Availability

• Tackling the Challenges

Page 13: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

13

Lesson Learned: Good Modeling Requires Good Data

• Availability and quality of data is an issue• Not enough historical data• Incomplete / unstructured data• Decentralization of data

• Reconciling data becomes very a very long and manual process under these conditions

Potential reconciliation between credit and accounting

Consider all of the exposures of a bank across multiple business

units!

Page 14: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

14

Lesson Learned: Data Warehousing & Resources

• Data Warehousing• Can help alleviate reconciliation by creating a “single source of

truth”• Time consuming, expensive, and vulnerable to scope creep• Implementation in phases to maximize real-time ROI is crucial

• Technical Resources (Hardware to support data and analysis initiatives)• Disc Space• Memory• CPU

• Human resources• Database administrators• System administrators• Programmers• Financial analysts & modelers

Page 15: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

15

Lessons Learned: Time Management

• Use time in the “off-season” wisely• Perform post mortem analysis as soon as possible after each

submission to establish a game plan for the next season• Off-season activities include:

• Training• System Installations• System Enhancements• Project Planning• Resource Planning

Page 16: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

Lesson Learned/Issues Uncovered: Data Availability

• Proxy data is acceptable but only a temporary solution• The Federal Reserve indicates:

• Banks must strive for better data:

• Developing high-quality internal data is a crucial project for improving a company’s stress testing estimation practices.

• Agencies encourage companies to take ownership of stress tests rather than relying on vendors

• Companies should have in place effective model risk management practices, including validation, for all models used in stress tests.

“Companies are expected to have appropriate management information systems and data processes that enable them to collect, sort, aggregate, and update data and other

information efficiently and reliably within business lines and across the company for use in…stress tests.”

Page 17: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

Tackling the Challenges

• Create a cross-functional steering committee to bring business units together

• Use gap analysis to evaluate the enterprises readiness in key areas

• Data• Modeling• Human resources• Governance• Process

Page 18: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

18

Tackling the Challenges

• Stress Testing requires results to be used in decision making• Maximize returns by using data and business intelligence

generated in the Stress Testing process beyond the evaluation of capital

• Potential benefits:• Consistent enterprise data management processes• Improved modeling to support operational forecasting, ALLL,

ALM, etc.• Better data to support portfolio and customer analysis

Page 19: Stress Testing Modeling: Finding the ‘Fault Lines’ in Risk Management through Dynamic Stress Test Modeling

19

Tackling the Challenges

Governance• Regulators to continue to take a strong look at the governance process• Focus on both data management and the qualitative analysis

Stronger model validation• Banks should strive to place more formal processes around creation, management and validation• Regulators will review qualitative discussions to address how the model was challenged

• limitations, weaknesses and uncertainties in the model • the sensitivity of the model to these issues• what mitigating actions were taken

Emphasis on controls• Banks must be prepared to demonstrate that the models used by the business units are:

• utilizing consistent assumptions • maintaining balance consistency with a complete reconciliation of variances• translating model output is correctly into financial results

Enhanced qualitative analysis• Banks must improve results analysis and communication to management
