This is a fundamental term of the loan, and changes require a modification to the authorization. Unilateral changes by the lender are not permitted and would constitute a serious servicing violation, potentially jeopardizing the guaranty.","example":"A $1,000,000 7(a) loan is authorized with an interest rate tied to the Prime rate. Two years into the loan, the lender decides it prefers to use SOFR. The lender cannot simply change the base rate. Any such change would require a formal loan modification, mutual agreement with the borrower, and likely SBA approval.","what_lenders_check":"Lenders must ensure strict adherence to the authorized loan terms, particularly the base rate. Any deviation can lead to borrower disputes, regulatory non-compliance, and severe issues with the SBA guaranty. Clarity and transparency with the borrower regarding the chosen base rate are paramount.","required_facts":["Base rate option","Variable rate","Loan authorization","Unilateral change","Post-closing modification"],"source_families":["7(a) Alternative Base Rate Options","SOP 50 10 - Lender and Development Company Loan Programs","13 CFR Part 120 - Business Loans"],"official_sources":[{"title":"7(a) Alternative Base Rate Options","url":"https://www.sba.gov/sites/default/files/2026-02/Procedural%20Notice%205000-875051-%207%28a%29%20Alternative%20Base%20Rates.pdf"},{"title":"SOP 50 10 - Lender and Development Company Loan Programs","url":"https://www.sba.gov/sites/default/files/2025-05/SOP%2050%2010%208%20Technical%20Updates%20effective%206.1.2025.docx"},{"title":"13 CFR Part 120 - Business Loans","url":"https://www.ecfr.gov/current/title-13/chapter-I/part-120"}],"related_questions":[{"question":"When is the use of the Wall Street Journal Prime Rate as the base rate mandatory for a variable rate 7(a) loan, if ever?","url":"https://dealroom.so/for-lenders/questions/when-is-the-use-of-the-wall-street-journal-prime-rate-as-the-base-rate-mandatory-for-a-var"},{"question":"What are the current allowable alternative base rate options for variable rate 7(a) loans, besides Prime Rate?","url":"https://dealroom.so/for-lenders/questions/what-are-the-current-allowable-alternative-base-rate-options-for-variable-rate-7-a-loans-b"},{"question":"What is the specific maximum interest rate a lender can charge on a variable rate 7(a) loan?","url":"https://dealroom.so/for-lenders/questions/what-is-the-specific-maximum-interest-rate-a-lender-can-charge-on-a-variable-rate-7-a-loan"},{"question":"Can a lender unilaterally increase the interest rate on a variable rate 7(a) loan?","url":"https://dealroom.so/for-lenders/questions/can-a-lender-unilaterally-increase-the-interest-rate-on-a-variable-rate-7-a-loan"},{"question":"What are the current alternative base rate options for variable rate 7(a) loans?","url":"https://dealroom.so/for-lenders/questions/what-are-the-current-alternative-base-rate-options-for-variable-rate-7-a-loans"},{"question":"How are variable interest rate adjustments determined for an SBA 7(a) loan?","url":"https://dealroom.so/for-lenders/questions/how-are-variable-interest-rate-adjustments-determined-for-an-sba-7-a-loan"}],"related_terms":[{"term":"Prime Rate","url":"https://dealroom.so/glossary/prime-rate"},{"term":"Base rate","url":"https://dealroom.so/glossary/base-rate"},{"term":"SOFR ABR","url":"https://dealroom.so/glossary/sofr-abr"},{"term":"Option to renew","url":"https://dealroom.so/glossary/option-to-renew"},{"term":"WSJ Prime rate","url":"https://dealroom.so/glossary/wsj-prime-rate"},{"term":"SOFR-based rate","url":"https://dealroom.so/glossary/sofr-based-rate"}],"related_tools":[{"name":"SBA 7(a) payment & fee calculator","url":"https://dealroom.so/sba-7a/calculator"},{"name":"Find an active SBA 7(a) lender","url":"https://dealroom.so/lenders"}],"data_freshness":{"last_reviewed":"2026-06-13","sba_rule_sources_checked_through":"2026-06-13"},"citation":{"label":"DealRoom.so SBA 7(a) Q&A","url":"https://dealroom.so/for-lenders/questions/can-a-lender-change-the-base-rate-option-e-g-from-prime-to-sofr-for-a-variable-rate-7-a-lo","source_type":"DealRoom Q&A"},"caveats":["Grounded in the current SBA rulebook; verify against official sources before relying on it for a live deal.","Not legal, tax, or financial advice and not an approval decision."]}
