SBA 7(a) Q&A
Short answer
The SBA sets maximum allowable interest rates for 7(a) loans, and lenders must adhere to these caps, which are monitored through loan authorization reviews and regulatory oversight.
The SBA establishes a maximum interest rate (base rate plus a spread) that lenders can charge on 7(a) loans. This cap protects borrowers from excessive rates. Lenders must document their chosen rate within these limits in the loan authorization.
If the maximum allowable interest rate for a $500,000 loan is Prime + 2.75%, a lender cannot charge Prime + 3.00%. The SBA reviews loan authorizations to ensure this cap is respected.
Insider move
Lenders are acutely aware of SBA interest rate caps. Charging above the maximum rate is a compliance violation that could lead to a guaranty repair or denial, so they diligently apply the correct rates.
