SBA loan basics
Short answer
If you have a variable-rate SBA 7(a) loan, your interest rate will likely decrease if general market interest rates, particularly the Prime Rate, go down significantly.
Variable-rate SBA 7(a) loans are tied to a fluctuating base rate, most commonly the Wall Street Journal Prime Rate. When this base rate decreases, the borrower's interest rate (Prime + lender's spread) will also decrease at the next scheduled adjustment period, resulting in lower interest payments.
A business has a variable-rate SBA loan at Prime + 2.75%. If the Prime Rate drops from 8.50% to 7.00% due to market changes, the loan's interest rate would decrease from 11.25% to 9.75% (7.00% + 2.75%) at the next quarterly adjustment, reducing the monthly interest portion of their payment.
