The question banks now must address is how they should modify their stress-testing policies and processes to adapt to the post-DFAST environment. The objective would be to continue achieving the benefits stress testing can provide, while at the same time taking advantage of opportunities to achieve cost savings due to the elimination of certain DFAST compliance and reporting requirements.
Among the likely savings are reductions in governance costs associated with DFAST oversight, model risk management, and the associated effective challenge, documentation, submission, and examination activities. Industry experience suggests these can represent anywhere from 30 to 60 percent of the effort involved in maintaining a DFAST framework.
In addition to internal cost savings, many banks might be able to reduce outsourcing costs. Alternatively, some banks might find it more advantageous to consider outsourcing additional components – or even the entire forecast and modeling effort – in order to achieve greater cost savings in terms of internal resources.
As attractive as the savings opportunities are, it is important to remember that stress testing as a practice is not solely a DFAST creation. Various other regulations require banks to have stress-testing capabilities as part of their capital management and governance structure.
Looking beyond compliance alone, stress testing is a proven tool for providing management with useful insights and value. In the post-DFAST environment, many banks should plan to refocus and reprioritize their forecasting approaches to align more closely with their business priorities, particularly in the area of credit risk management. Many of the DFAST models – and the data they collected – can be adapted to support allowance for loan and lease losses (ALLL) calculations, particularly as banks adapt to the new current expected credit loss (CECL) standard.
Stress testing’s role in capital planning
Looking beyond its immediate risk management applications, stress testing should be regarded as an integral part of the broader capital planning production framework. In this area, the practice of stress testing can make a particularly direct and significant contribution.
The disciplined application of stress testing can provide critically needed support and insight in all stages and to all participants in the capital planning process, from initial risk identification to the actual assessment of how much capital a designated risk might require. Carrying the effort forward, stress testing and other types of sensitivity analyses also can be helpful in determining how capital assessments could be altered by changes to the business plan or strategy. Guidance on how to proceed can be found in the Office of the Comptroller of the Currency’s recently updated handbook.

The regulatory relief provided by the
Economic Growth, Regulatory Relief, and Consumer Protection Act is both welcome and significant. Yet, ultimately, most leading banking organizations are looking upon this situation as an opportunity to improve and customize their stress-testing regimens, rather than eliminating this valuable practice altogether.
