What Is Credit Risk?

Credit risk is the most fundamental risk a bank faces. Every time a bank makes a loan — whether a home mortgage, auto loan, business line of credit, or credit card — it takes on the risk that the borrower may not repay. Managing this risk through underwriting standards, portfolio diversification, pricing, and monitoring is the core competency of banking.

Banks manage credit risk at multiple levels. At origination, loan officers evaluate borrower creditworthiness using credit scores, income verification, collateral appraisals, and debt-to-income ratios. At the portfolio level, banks set concentration limits to avoid having too much exposure to any single borrower, industry, or geographic area. Regulators examine these practices during bank examinations and assign ratings under the CAMELS system.

For depositors, credit risk matters because large loan losses can erode a bank's capital base, potentially triggering regulatory action or even failure. The BankHealthData score captures credit risk primarily through the nonperforming loan ratio, which measures the current level of problem loans. When evaluating your bank's safety, pay attention to the concentration of its lending — a bank heavily concentrated in commercial real estate, for example, faces different credit risks than one focused on residential mortgages. Banks with diversified loan portfolios tend to be more resilient to sector-specific downturns. The quarterly trend in your bank's credit metrics on BankHealthData can reveal whether risk is building or receding.
