SBA loan basics
Short answer
No, the SBA does not dictate the exact interest rate. Instead, it sets maximum allowable interest rates, giving lenders some flexibility to price loans competitively based on risk and market conditions.
The SBA establishes a ceiling for interest rates, typically a base rate (like Prime) plus a maximum permissible spread. Lenders are free to negotiate rates with borrowers up to this maximum. This allows for competition among lenders and for rates to reflect the individual borrower's credit risk and the overall economic environment.
If the SBA allows a maximum rate of Prime + 2.75%, a lender might offer a strong borrower Prime + 2.00% to win their business. For a riskier borrower, the lender might offer Prime + 2.75%, but they cannot exceed that cap.
