What is diversification and why is it important in a loan portfolio?

• A. Spreading risk across borrowers, sectors, and geographies to reduce concentration risk and potential losses.
• B. Concentrating loans in a single industry to maximize efficiency.
• C. Holding only government securities.
• D. Ignoring geographic differences in credit risk.

Answer: (A)

Diversification means spreading exposure across borrowers, sectors, and geographies to prevent any single source of loss from having a large impact on the portfolio. In a loan portfolio, concentrating heavily in one borrower, one industry, or one country creates concentration risk: if that borrower defaults, if that sector enters a downturn, or if that region faces trouble, losses can be large and affect many loans at once. By mixing credit types, industries, loan sizes, and locations, you smooth out the risk and improve the odds that not all parts of the portfolio perform poorly at the same time. Diversification helps stabilize cash flows, protect capital, and support more predictable earnings, which is helpful for risk management and regulatory considerations. It does not eliminate risk—systemic events can still impact multiple areas—but it reduces idiosyncratic risk and the potential for large, correlated losses. The other approaches— concentrating in a single industry, holding only government securities, or ignoring geographic differences—increase concentration risk and reduce diversification benefits.
