The Financial Sector Assessment Program (FSAP) performs bank stress testing to evaluate the resilience of the banking sector to different unexpected shocks, including sharp changes in the interest rate or exchange rate. In addition to macroeconomic shocks like these, the soundness of the banking sector also depends on the soundness of bank borrowers: systemic shocks to borrowers’ ability to repay loans is transmitted to banks through corporate defaults.
For example, an interest rate shock may affect banks directly, through its impact on the income and expenses from their lending practices. In addition, if the interest rate shock affects borrowers’ ability to repay, the shock will also be transmitted to the banking sector through an increase in corporate defaults. Similarly, a negative shock to corporate earnings will manifest as higher default rates and also adversely affect bank stability.
Assessment of corporate vulnerability thus would strengthen the analysis of bank vulnerability to shocks and should play an important role in bank stress testing. Unfortunately, assessment of corporate vulnerability is rarely included in the FSAP’s standard bank stress testing.
