U.S. stablecoin regulation under the GENIUS Act is expanding beyond the FDIC’s proposed prudential framework, with the Treasury Department’s FinCEN and OFAC now set to jointly propose rules focused on anti-money-laundering and sanctions compliance. The new requirements would apply to U.S. stablecoin issuers and would obligate them to build systems capable of intercepting, freezing, and rejecting suspicious transactions under Bank Secrecy Act standards. This adds a more specific enforcement and transaction-monitoring layer to the existing FDIC proposal, which already covered reserve assets, redemption, capital considerations, enterprise-wide risk management, and issuer certifications on AML and sanctions compliance for FDIC-supervised entities.
