In many cases, scenarios are run by creating multiple versions of the same model, requiring a significant time commitment for each iteration. Scenario modelling should be implemented as part of the BAU process, but from our experience working with many different businesses, this is often an exercise that is overlooked. This chart shows the extremes of key macroeconomic assumptions in the BoE’s 2019 stress testing scenario. In practice, this typically means modelling the impact of hypothetical adverse macroeconomic and financial market scenarios on bank profitability and balance sheets.” Engineers stress test construction materials by measuring their behaviour when subjected to strain.īank stress testing is designed to test the resilience of banks to severe but plausible shocks. Doctors perform cardiac stress tests by getting patients to run on treadmills and monitoring their pulse and blood pressure. “Analysing how an object or system copes under pressure. In a note to financial institutions, Bank of England (“BoE”) summarised stress testing as: Often the primary question of the analysis is “Does the business have enough cash or funding headroom to weather the current situation and remain solvent?” Although this is a requirement for financial institutions, forecasting or “modelling” the impact of a range of scenarios on financial performance is an important practice for all businesses. In recent years, “stress testing” has become synonymous with the banking sector following the introduction of requirements for banks to simulate a range of adverse hypothetical scenarios such as market shocks and severe recessions to understand resilience.
