SIFMA and SIFMA AMG have asked FinCEN and the Office of Foreign Assets Control to clarify how anti-money laundering, sanctions, and compliance duties should apply to payment stablecoin issuers under the GENIUS Act. Their message is blunt: without changes, parts of the framework may be difficult to execute in practice.
The filing is also a sign that large financial institutions are preparing for broad involvement in stablecoins. SIFMA’s member firms expect activity across issuance, custody, reserve management, Treasury-market operations, repo-market activity, institutional settlement infrastructure, and securities-related stablecoin services. Stablecoins are no longer being treated as a narrow crypto product.
Secondary-market activity is the main fault line
The central issue in SIFMA’s recommendations is what happens after stablecoins begin circulating on public blockchain networks. The group wants regulators to state more clearly when an issuer is expected to freeze transactions, block transfers, reject payments, restrict wallet activity, or enforce sanctions controls. That question goes to the core of how digital dollars are supposed to function once they leave the issuer’s immediate perimeter.
In traditional finance, firms usually have direct visibility into customer identities and account relationships. Stablecoins work differently. Once tokens move through public chains and across platforms, issuers may not have full visibility into wallet holders, counterparties, transaction intent, cross-platform transfers, or broader secondary-market activity. SIFMA argues that digital asset service providers and intermediaries often see more of the transaction chain than issuers do.
The group also called for legal safe-harbor protection for stablecoin issuers that act in good faith when restricting or freezing transactions, echoing protections already available in traditional finance.
Stablecoin oversight now touches the Treasury market
The letter reaches beyond crypto policy. Dollar-backed stablecoin issuers typically hold reserves in Treasury bills, cash-equivalent instruments, repo agreements, and short-duration government debt, which means stablecoin growth is becoming linked to the functioning of the US Treasury market itself. SIFMA members specifically pointed to expected involvement in repo and Treasury markets tied to payment stablecoin infrastructure.
That creates a difficult policy balance. Regulators want strong AML enforcement, sanctions compliance, transaction traceability, and financial-stability safeguards. Stablecoins, by contrast, draw much of their utility from programmability, global transferability, blockchain interoperability, real-time settlement, and fewer intermediaries. The way those pressures are reconciled will shape how digital dollars fit into institutional settlement, cross-border transfers, and DeFi.
Travel Rule standards remain unsettled
SIFMA also asked regulators to recognize industry-built compliance standards and risk-based approaches for stablecoin transfers under the Travel Rule. That request points to growing demand for standardized institutional compliance infrastructure on blockchain rails.
The broader dispute is no longer about whether stablecoins will matter. It is about how existing compliance systems can be applied to blockchain-based networks where issuers often do not control secondary-market activity in the way banks control accounts inside conventional payment systems.
