US banks seek stricter AML for stablecoins

TLDR

US banking groups are urging US regulators to tighten anti?money?laundering rules around stablecoins, especially for activity on DeFi platforms and exchanges.

1. Major bank lobbies say most illicit stablecoin activity happens in secondary markets and want clearer AML duties for DeFi, custodians, and exchanges.
2. Crypto industry groups warn that overbroad rules could make issuers liable for user activity and push regulated stablecoins away from permissionless DeFi, even though on?chain controls already exist.
3. The outcome of FinCEN and OFAC rulemaking and the CLARITY and GENIUS Acts will shape how much KYC, blacklisting, and monitoring attaches to everyday stablecoin use in the US.

Deep Dive

1. Bank Demands On Stablecoins

Two major US banking trade groups, the Bank Policy Institute and The Clearing House, sent joint letters to FinCEN and OFAC arguing that stablecoin AML rules are too focused on issuers and do not adequately cover secondary markets such as DeFi protocols, digital asset custodians, and crypto exchanges. They say regulators themselves acknowledge that the majority of illicit finance involving payment stablecoins occurs on the secondary market, and want explicit AML and sanctions obligations on intermediaries that facilitate those transactions rather than just on the issuer side.

Their proposal emphasizes a risk based approach where banks and other intermediaries focus compliance resources on higher risk activity instead of check?the?box procedures, but the direction of travel is clearly toward more robust monitoring and enforcement in the stablecoin ecosystem.Bank groups letter summary highlights that this debate sits inside a broader FinCEN and OFAC review of digital asset AML rules.

2. Tension With Crypto Industry

Crypto policy groups are pushing back on how far these rules should go. Paradigm and the Hyperliquid Policy Center warned that implementing the GENIUS Act in a way that makes issuers responsible for secondary market activity they cannot see would likely drive compliant dollar stablecoins away from permissionless DeFi and toward walled gardens.Their letter argues stablecoins should be treated more like cash once in circulation.

The Blockchain Association takes a middle line, supporting issuer?focused AML and sanctions controls on issuance, redemption, reserves, and fiat ramps, but opposing rules that classify peer to peer transfers as issuer intermediated activity.Its comments say that would harm utility without meaningfully improving enforcement. Meanwhile, dYdXs foundation CEO notes that major stablecoins already have blacklist and freeze functions and that leading DeFi frontends perform on?chain screening, suggesting the real gap is offshore exchanges and unhosted wallets, not all DeFi.

3. Key Rulemaking To Watch

Several processes now interact.

1. FinCEN and OFAC are working on GENIUS Act rules that will define AML and sanctions requirements for permitted payment stablecoin issuers and, potentially, for downstream intermediaries.
2. The CLARITY Act, a broad crypto market framework in the Senate, is another battleground, with banks opposing stablecoin reward and yield provisions and arguing that AML and Bank Secrecy Act protections are still insufficient.Recent coverage shows intense bank lobbying.
3. Industry and banking letters together increase the odds that DeFi frontends, custodians, and US?serving exchanges will face clearer, possibly stricter, AML expectations around stablecoins in the next regulatory cycle.

Conclusion

US banks are trying to shift AML focus from just stablecoin issuers onto the full transaction chain, especially DeFi and exchanges, framing secondary markets as the real risk point. Crypto industry responses aim to keep that shift from effectively banning permissionless usage or saddling issuers with impossible surveillance duties. How regulators balance those positions will determine whether stablecoins evolve toward bank?like rails with heavier controls or remain closer to todays open, cash?like model in much of the ecosystem.
