Capital is central to a bank holding company’s ability to absorb unexpected losses and continue to lend to creditworthy businesses and consumers. Regulators in the U.S. are setting high standards on a bank holding company’s internal capabilities for assessing and stress testing capital adequacy by various scenario conditions as an integral part of their overall risk management and capital planning framework. Stress testing and capital planning has gone through multiple iterations and evolved significantly over time since the Supervisory Capital Assessment Program (SCAP) review was initiated in 2009. In this paper, we explore the guidelines, common challenges, accelerators and recommendations for stress testing and capital planning.
