What the Oklahoma Maximum Interest Rate Means
Usury means charging more interest than the law allows. Oklahoma has two different numbers: a default “legal rate” that applies only when a contract says nothing about interest, and separate limits on what a lender and borrower can agree to in writing. Under the Oklahoma Constitution (Art. XIV, Sec. 2), the Legislature sets those agreed-rate limits, mostly through the Uniform Consumer Credit Code (Title 14A).

Who the Oklahoma Maximum Interest Rate Applies To
Lenders that don’t hold a license generally face the base consumer-loan ceiling in 14A O.S. 3-201. Licensed “supervised lenders” may charge the higher rates set in 14A O.S. 3-508A, which were changed in 2023 to tie in the federal funds rate. Banks chartered in other states and national banks can usually charge the rate allowed where they are based. Non-consumer loans follow 14A O.S.
3-605, and pawnshops are covered by a separate law (59 O.S. 1510).
Credit Cards and the Oklahoma Maximum Interest Rate
Federal law (12 U.S.C. 85 and the Marquette decision) lets a national bank charge the interest rate allowed in its home state to customers anywhere in the country. So a card from a bank in a state with no cap or a high cap can legally charge more than an Oklahoma lender could. In most cases the card agreement names the state law that controls the rate.
What Happens When a Lender Breaks the Oklahoma Maximum Interest Rate
Under Okla. Const. Art. XIV, Sec. 3, knowingly charging more than the lawful rate generally forfeits all the interest on the debt. A borrower who has already paid the extra interest may sue to recover twice that amount within two years after the loan comes due.
Title 14A also treats charges above what the Code allows as “excess charges” that may be refunded, and the Department of Consumer Credit can bring administrative actions and civil penalties. Confirm the current remedies, and any criminal penalty, with the statute, the court clerk or an attorney.
How to Check a Loan Against the Oklahoma Maximum Interest Rate
1) Find the APR and the finance charge in the federal Truth in Lending disclosure on your loan papers. 2) Note what kind of loan it is (consumer, supervised/licensed, non-consumer or pawn) and who the lender is. 3) Look up the lender’s license on the Department of Consumer Credit website. 4) Compare the APR with the ceiling in the Title 14A section for that loan type.
5) If the numbers don’t match, the department or an attorney can confirm.

The Oklahoma Constitution sets a fallback rule: if the Legislature hasn’t set a maximum rate, any contract above 10% a year is usurious. The Oklahoma Supreme Court held in Barnes v. Helfenbein, 548 P.2d 1014 (Okla. 1976), that passing the Consumer Credit Code made that 10% limit inapplicable to loans the Code covers.
