Stress testing is an essential risk management tool used to assess a bank's potential vulnerabilities to stressed business conditions. Stress testing involves the use of various techniques to assess a bank's existing and potential vulnerability (typically in terms of its profitability, liquidity and capital adequacy) to 'stressed' business and economic conditions and plays an important role in the management of risk by banks. Effective stress testing enables a bank to quantify adverse unexpected outcomes related to a variety of risks and facilitate the decision to put in place risk mitigation plans to safeguard its safety and soundness. This includes providing a sufficient amount of financial resources (including capital and liquidity) and implementing other risk mitigation strategies that are required to withstand losses arising from a particular stressed scenario.
July 2018ST-1.1.3
Stress testing can be used for multiple purposes within the bank. While this Directive is focused on the integrated firm-wide stress testing which serves to identify weaknesses and vulnerabilities in a bank's risk profile and in turn evaluate its capital adequacy and liquidity position under adverse scenarios, stress testing should also be conducted for recovery planning and ICAAP. However, the underlying methodologies for scenario development and stress testing should be consistent regardless of whether they are used for firm-wide stress testing, ICAAP or recovery planning.
