How Credit Stress Testing Can Help Build Resilience BY MICHAEL JOHNSON, SVP & Southwest Regional Manager, PCBB Recent banking crises and economic shocks have highlighted vulnerabilities in the financial system, prompting increased regulatory stress testing and stricter capital requirements — particularly for larger banks. However, regulatory guidance encourages all institutions, including community banks, to conduct some level of stress testing or scenario analysis to proactively manage risk and enhance financial resilience. WHY CREDIT STRESS TESTING MATTERS FOR COMMUNITY BANKS While stress testing can apply to all areas of your bank — including liquidity, interest-rate sensitivity and operations — credit stress testing is particularly crucial for community banks, given their challenges with quickly acquiring capital or funding. Simulating extreme market scenarios helps institutions assess the potential impact of economic disruptions on loan portfolios, providing insights that strengthen risk management and inform strategic decision-making. By proactively identifying vulnerabilities, community banks can refine lending criteria, adjust capital planning and integrate stress test results into their broader risk management framework. Regular testing, combined with well-defined policies and procedures, strengthens institutional resilience against market shocks and economic downturns. For example, using the results from credit stress testing, community banks can adjust lending criteria or diversify their portfolios to reduce exposure if they have concentrations in high-risk sectors. In another scenario, they may increase their capital buffers or secure additional funding if stress testing reveals the potential for significant losses or strained liquidity in certain adverse conditions. COMMON CREDIT STRESS TESTING SCENARIOS Community banks can apply credit stress testing to evaluate how adverse economic conditions could impact their loan portfolios. Common scenarios include: • Macroeconomic Shocks: Stress tests often assess the impact of shifts in key economic factors, such as rising inflation and interest rates, recessions, declines in GDP and surges in unemployment. These conditions can increase loan defaults, erode asset values and negatively affect borrower repayment capacity. • Market Disruptions: Community banks may also analyze the effects of stock market declines, housing market crashes, commodity price volatility or foreign currency fluctuations to determine how these external factors might impact credit portfolios and overall financial stability. DIFFERENT APPROACHES Community banks are able to flexibly customize — or even combine different types of — credit stress tests to suit their specific characteristics, market areas and strategic needs. This will help ensure they are effectively able to identify their unique risks and weaknesses. Two approaches that are well-suited to community banks and can be combined are: 1. Portfolio-Level Testing: This top-down approach estimates potential losses on loan portfolios in adverse conditions by aggregating loan-portfolio data based on shared characteristics. Utah Banker 14
