The Office of the Comptroller of the Currency (OCC) finalized its rules implementing the GENIUS Act, establishing the first federal regulatory framework for payment stablecoins. The rule takes effect on January 18, 2027, and sets standards for reserve backing, redemptions, capital, custody, audits, and risk management for national banks, nonbank companies, and foreign issuers under OCC jurisdiction.

A significant departure from the February proposal is the removal of a presumption that third-party rewards programs violate the statutory ban on issuer-paid interest. While the GENIUS Act prohibits issuers from paying yield to holders, it does not explicitly address exchanges offering rewards. Banking groups had lobbied to close this "stablecoin loophole," arguing such yields could drain deposits. The final rule instead adopts a case-by-case review approach, allowing market development while retaining agency authority to pursue clear evasions of the ban.

The OCC also eased several reserve management restrictions. It scrapped a 20-day weighted-average maturity limit on reserve assets, permitting issuers to hold longer-dated Treasuries. Issuers may now withdraw surplus reserves at any time, provided outstanding stablecoins remain backed one-to-one. Regarding redemptions, the agency removed provisions extending deadlines during withdrawal surges but requires issuers to notify the OCC within 24 hours if redemption requests exceed 10% of a stablecoin’s outstanding value in a single day. Anti-money laundering and sanctions rules will be addressed in a separate rulemaking with the Treasury.
