Capital Adequacy Pre‐ and Postcrisis and the Role of Stress Testing
金融危机暴露了传统资本充足方法的不足，压力测试在危机后成为评估银行资本充足性和抗冲击能力的主要工具，但和平时期过度依赖压力测试可能带来新的风险集中。
Abstract The financial crisis forced the development of new approaches for determining capital adequacy in banks since extant methods clearly did not prepare banks or their supervisors sufficiently. The success of stress testing as a crisis response tool, particularly in the U.S. in 2009, has led to its adoption postcrisis as the tool of choice for assessing capital adequacy in banks and testing resiliency to economic and financial shocks. But the increased reliance on stress testing in financial peacetime has given rise to a new risk concentration, namely, in the rather narrow set of scenarios and their translation to outcomes and impact on bank financials.
