The U.S. Department of the Treasury has proposed applying Bank Secrecy Act and anti-money-laundering requirements to stablecoin issuers operating under the GENIUS Act, the federal framework that regulates payment stablecoins, according to a notice flagged by the legal publication JDSupra.

The proposal, if adopted, would formally bring issuers of payment stablecoins within the regulated perimeter of the BSA, the statute that obliges financial institutions to maintain compliance programs, verify customer identities, monitor transactions and file suspicious activity and currency transaction reports with the Financial Crimes Enforcement Network (FinCEN).

The move follows Congress's passage of the GENIUS Act, which established a federal licensing and supervision regime for payment stablecoin issuers. The statute requires issuers to maintain full reserve backing in cash and short-term Treasuries and subjects them to oversight by federal regulators. The new Treasury proposal extends that supervision into the AML sphere, spelling out how BSA obligations attach to entities that issue fiat-backed tokens on public blockchains.

For issuers, the operational consequences would be substantial. Compliance functions familiar to banks and money services businesses — know-your-customer onboarding, transaction monitoring, sanctions screening and recordkeeping — would need to operate against stablecoin issuance and redemption flows. Because stablecoins move on permissionless rails, including Ethereum and other smart-contract chains, issuers will face hard questions about how far their monitoring obligations reach when tokens circulate through decentralized exchanges, non-custodial wallets and secondary markets beyond their direct customer base.

Treasury's initiative signals that regulators view the issuer, not the blockchain infrastructure, as the control point for AML compliance. An issuer that cannot demonstrate an effective compliance program risks losing its authorization under the GENIUS Act framework, a threat that carries more weight than a civil penalty alone. The proposal effectively aligns U.S. stablecoin regulation with the approach applied to traditional payment institutions: the license is conditional on continuous AML performance.

The rulemaking also narrows the competitive ambiguity that has surrounded offshore issuers. Stablecoins circulating in the U.S. market without a compliant issuer behind them would face a clearer enforcement theory, since Treasury's proposal articulates the specific BSA obligations that issuers must satisfy. Banking partners and exchanges listing payment stablecoins will likely translate the proposal into listing and due-diligence standards of their own, tightening the channel between regulatory status and market access.

Legal practitioners following the process expect the standard notice-and-comment sequence: publication in the Federal Register, a public comment window during which issuers, exchanges and industry groups can respond, and subsequent revision before finalization. Compliance teams at major issuers will use that window to press for clarity on practical questions — the treatment of secondary-market transfers, the design of Travel Rule obligations for stablecoin transactions, and the interaction between federal requirements and state money-transmitter regimes.

The proposal now enters its comment period, and issuers operating under or seeking authorization under the GENIUS Act will need to assess how quickly final BSA/AML rules follow, since the gap between licensing and enforceable compliance obligations is the window in which their operational and legal exposure will be defined.
