SBA loan basics
Short answer
Banks benefit from an SBA 7(a) loan primarily through the SBA's partial guarantee, which reduces their risk and allows them to lend to a broader range of small businesses.
The SBA guarantee protects the lender from a portion of the loss if the borrower defaults, making loans to riskier or less established small businesses more attractive. This expands the bank's potential customer base and allows them to meet community reinvestment goals. Lenders can also sell the guaranteed portion of the loan on the secondary market, improving their liquidity.
ABC Bank approves a $1 million SBA 7(a) loan with a 75% guarantee. If the borrower defaults, the SBA covers $750,000 of the outstanding principal, significantly reducing ABC Bank's potential loss.
