The Office of the Comptroller of the Currency (OCC) is set to close its comment period for the GENIUS Act stablecoin rules on May 1, marking the end of an 18-month period of regulatory uncertainty for U.S. banks considering stablecoin issuance. This deadline is crucial for corporate treasurers who have been evaluating stablecoins as a primary payment method but lacked formal federal guidance. The proposed rule, introduced on February 25, outlines a two-tier licensing framework, placing the compliance burden on issuers rather than payment infrastructure operators. Issuers with over $10 billion in stablecoins will require federal licensing, while smaller firms can operate under state regimes certified by the Treasury, Federal Reserve, and FDIC. The American Bankers Association has requested an additional 60 days to review the proposal, indicating potential delays in the final rule's publication.
