Peer review of supervisory authorities' implementation of stress testing principles
Stress testing is an important tool used by banks to identify the potential for unexpected adverse outcomes across a range of risks and scenarios. In 2009, the Committee reviewed the performance of stress testing practices during the financial crisis and published recommendations for banks and supervisors entitled Principles for sound stress testing practices and supervision.
As part of its mandate to assess the implementation of standards across countries and to foster the promotion of good supervisory practice, the Committee's Standards Implementation Group (SIG) conducted a peer review during 2011 of supervisory authorities' implementation of the principles. The review found that stress testing has become a key component of the supervisory assessment process as well as a tool for contingency planning and communication. Countries are, however, at varying stages of maturity in the implementation of the principles; as a result, more work remains to be done to fully implement the principles in many countries.
Overall, the review found the 2009 stress testing principles to be generally effective. The Committee, however, will continue to monitor implementation of the principles and determine whether, in the future, additional guidance might be necessary.
