Treasury targets stablecoins for anti‑illicit finance rules

A stablecoin is supposed to feel like a digital dollar that moves at internet speed. The Treasury Department just told issuers that if they want that privilege in the United States, they also need the compliance machinery of a real financial institution. (americanbanker.com) On April 8, 2026, the Financial Crimes Enforcement Network and the Office of Foreign Assets Control proposed a joint rule under the GENIUS Act, the stablecoin law Congress passed in 2025. The proposal would require payment stablecoin issuers to run anti-money-laundering programs and sanctions programs, not just promise that their tokens are backed. (cointelegraph.com, congress.gov) That changes the picture of what a stablecoin company is. Under the proposal, an issuer is less like a software app that publishes tokens and more like a payments company that has to watch for dirty money, keep records, and report suspicious activity. (bankingjournal.aba.com, cointelegraph.com) The GENIUS Act, short for the Guiding and Establishing National Innovation for U.S. Stablecoins Act, became law on July 18, 2025 after passing the Senate 68-30 and the House 308-122. It created a federal framework for “payment stablecoins,” which are digital tokens that promise redemption at a fixed value, usually $1. (congress.gov) That law already did the consumer-facing part. It said issuers must be licensed, hold one-to-one reserves in cash or similar liquid assets, disclose redemption policies, and publish monthly reserve details. (congress.gov) The new proposal is the crime-control part. Treasury says issuers would need risk-based anti-money-laundering and countering-the-financing-of-terrorism programs, effective sanctions compliance programs, due diligence, recordkeeping, and suspicious activity reporting. (bankingjournal.aba.com, cointelegraph.com) One line in the law has gotten the industry’s attention for months: issuers must be able to freeze tokens tied to illicit activity. Legal analyses of the GENIUS Act noted that this power reaches even tokens sitting in self-custody wallets, not just coins parked on an exchange. (steptoe.com) That is why this is bigger than a paperwork update. If a stablecoin can be blocked, frozen, or rejected under federal rules, it starts to look less like bearer cash on a blockchain and more like a programmable bank deposit with a compliance switch attached. (cointelegraph.com, steptoe.com) The timing also matters because other agencies are moving in parallel. On April 7, 2026, the Federal Deposit Insurance Corporation proposed its own GENIUS Act rule covering reserve assets, redemptions, capital, risk management, and custodial services for the stablecoin issuers it supervises. (fdic.gov) Put those pieces together and the U.S. is building a full payments rulebook around stablecoins. The old argument was whether stablecoins should be allowed at all; the new argument is what kind of regulated payment rail they become once Treasury, bank regulators, and sanctions officials all have a hand on the controls.
