FinCEN Proposes Lenient Stablecoin Rules for Secondary Trades as OFAC Demands Transaction‑Blocking Power

Regulators are drawing a line between primary issuance and everyday trading of stablecoins. Bill Hughes called the joint FinCEN‑OFAC draft under the GENIUS Act one of the most important regulatory steps of the year, noting it could set a baseline for future AML and enforcement policy. He added that the outcome may influence how the SEC and CFTC treat crypto assets.

FinCEN’s draft treats secondary market stablecoin transactions as exempt from customer verification, ongoing monitoring, and suspicious transaction reporting. The agency argues that imposing those duties would create more operational burden than benefit for routine trades. By contrast, OFAC’s draft obliges issuers of payment‑oriented stablecoins to build the technical ability to block, freeze, and reject prohibited transactions in both primary and secondary markets, including peer‑to‑peer transfers between self‑custody wallets.

Market data shows the tension. USDT (Tether) holds a market cap of roughly $83.4 billion, USDC about $28.1 billion, and BUSD near $5.2 billion. Over the past 24 hours, USDT traded at $1.0002 (+0.02 %), USDC at $0.9998 (‑0.02 %), while the total crypto market cap stood near $1.2 trillion. These figures illustrate that even small deviations from the dollar peg can move billions of dollars in value.

The proposed rules mean stablecoin operators may need to embed filtering logic directly into smart contracts to satisfy OFAC, while avoiding KYC layers for secondary trades under FinCEN. If enforced, issuers could become de facto permissioned network operators, sparking debates over censorship and centralized control. Market participants will watch for clarification on whether proactive on‑chain monitoring is required and how issuers plan to implement blocking functions without undermining the open nature of blockchain transactions.

What to watch next: the final version of the GENIUS Act draft and any public comment period that could refine the balance between permissive trading and stringent sanctions enforcement.
