Stress testing is an analytical technique to show how a financial services company or bank will be affected by certain financial events or situations. In other words, it shows what can happen and how well prepared institutions are when certain stressors are introduced.

Key points:

• Stress testing is generally a computer-simulated technique to analyze how banks and investment portfolios perform in case of adverse economic scenarios.
• Banks use it to measure investment risk and the adequacy of assets and help evaluate internal processes and controls.
• Portfolio managers use internal stress-testing programs to evaluate how well the assets they manage might weather certain market occurrences and external events.
• Retirement and insurance portfolios are also frequently stress-tested to ensure that cash flow, payout levels, and other measures are well aligned.
• Regulators carry out stress tests to ensure that the capital holdings and other assets of such institutions are adequate. This is called ‘regulatory stress testing’.
  • BASEL III also requires the administration of stress tests by Banks for various crisis scenarios.
  • RBI conducts bi-annual stress tests for RBI’s Financial Stability Report (FSR). RBI had found Banks and NBFCs adequately capitalized for any economic stresses but found Urban Cooperative Banks (UCB) vulnerable (2022).
• Monte Carlo simulation is one of the most widely known. This type of stress testing can be used for modeling probabilities of various outcomes given the various economic variables, such as inflation, forex rate, interest rates, unemployment rates etc.
• Other types of stress tests are: Historical (response to similar events as in past is evaluated) and Hypothetical stress tests (response to various possible events/shocks is examined).
