The Office of the Comptroller of the Currency (OCC) has issued its final GENIUS Act rule on stablecoins, effective January 18, 2027. The rule eliminates a proposed automatic seven-day redemption extension and defines timely redemption as the point at which the issuer sends the money, not when an external bank makes funds available. It retains an ordinary ceiling of two business days for redemption requests. Issuers must notify the OCC within 24 hours if redemption requests exceed 10% of a brand's outstanding issuance value in a single 24-hour period. The rule also mandates monthly public reserve-composition reports and quarterly financial reports.
