The U.S. Treasury Department proposed new anti-money laundering rules for stablecoin issuers on April 8, 2026, marking the first federal AML framework aimed specifically at companies that issue dollar-pegged digital tokens. The joint rule, published by the Financial Crimes Enforcement Network (FinCEN) and the Office of Foreign Assets Control (OFAC), implements compliance obligations mandated by the GENIUS Act, the country’s first comprehensive stablecoin law, signed by President Trump in July 2025.
A stablecoin is a cryptocurrency pegged one-to-one to a fiat currency, typically the U.S. dollar, designed to maintain a steady price unlike Bitcoin or Ether. USDC (issued by Circle) and USDT (issued by Tether) are the two largest stablecoins, together representing over $200 billion in circulation.
- FinCEN and OFAC jointly proposed AML and sanctions compliance rules on April 8, 2026, targeting permitted payment stablecoin issuers (PPSIs) under the GENIUS Act.
- Covered issuers must establish AML/CFT programs, file suspicious activity reports (SARs), and build technical controls to block, freeze, or reject transactions tied to sanctioned entities.
- The 60-day public comment window opens upon Federal Register publication; final rules must be issued by July 18, 2026, with full enforcement no later than January 18, 2027.
- Tether, Circle, and any foreign stablecoin issuer serving U.S. users fall within scope. Non-compliance risks access to U.S. exchanges and dollar-clearing infrastructure.

What the proposed rule requires
The joint FinCEN-OFAC rule treats permitted payment stablecoin issuers (PPSIs) as financial institutions under the Bank Secrecy Act, the same legal category that covers banks and money services businesses. That classification triggers a full set of compliance obligations that stablecoin issuers have not previously faced in federal law.
Covered issuers must build and maintain an AML/CFT program with documented policies, a designated compliance officer, ongoing staff training, and independent testing. They must also file suspicious activity reports when transactions show signs of money laundering, fraud, or terrorist financing, the same reporting threshold applied to regulated banks.
On the sanctions side, OFAC’s portion of the rule requires PPSIs to adopt a risk-based compliance program built around five elements: senior management commitment, risk assessment, internal controls, regular testing, and employee training. Issuers must implement technical capabilities to screen counterparties against OFAC’s Specially Designated Nationals list and block or freeze transactions in real time when a match is found.
Treasury Secretary Scott Bessent stated in the announcement that the rules reflect the department’s commitment to “protect the U.S. financial system while supporting responsible innovation.” FinCEN separately noted it will not pursue enforcement actions against issuers whose programs meet the rule’s standards, absent significant or systemic failures.
Why this matters for Circle, Tether, and the broader market
The two largest stablecoin issuers face the sharpest compliance buildout. Circle, which issues USDC and went public in 2024, has invested in compliance infrastructure ahead of this rulemaking and welcomed the GENIUS Act at signing. Tether, which operates offshore and has historically disclosed less about its operations, faces more uncertainty: the GENIUS Act applies to any stablecoin “used by U.S. persons,” meaning Tether must either comply or risk being delisted from U.S.-regulated exchanges by enforcement deadline.
For smaller stablecoin projects and fintech platforms that issue tokenized dollar instruments, the rule creates a steep operational bar. Building out real-time OFAC screening and SAR-filing infrastructure requires dedicated compliance teams, legal resources, and core system integrations that smaller issuers may not have in place by January 2027.
The proposed rule also sends a market signal: Washington is moving to bring stablecoin issuers into the same compliance tier as banks, not treat them as lightly regulated tech companies. That shift has been anticipated since the GENIUS Act passed, but the April 8 rule is the first concrete implementation step with binding timelines.
Regulatory timeline and what comes next
The 60-day comment window opens when the rule is formally published in the Federal Register. Treasury must finalize regulations by July 18, 2026, a statutory deadline written directly into the GENIUS Act. Full enforcement begins January 18, 2027, or 120 days after final rules are issued, whichever comes first.
Separately, the Office of the Comptroller of the Currency proposed prudential reserve standards for stablecoin issuers in March 2026, covering reserve asset quality and liquidity requirements. Treasury also released a related notice of proposed rulemaking in early April establishing minimum standards for state-level stablecoin regulatory regimes to qualify as GENIUS Act-compliant alternatives to federal oversight.
The stacked rulemaking schedule means that by mid-2026, stablecoin issuers will face final or near-final standards across AML compliance, reserve requirements, and sanctions controls simultaneously, a compliance sprint that could reshape which firms can viably operate in the U.S. market by 2027.
Frequently Asked Questions
What is the GENIUS Act?
The GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins Act) was signed into law in July 2025. It established the first federal regulatory framework for payment stablecoins in the United States, requiring one-to-one reserve backing, regular audits, and AML compliance for issuers. It was the first major crypto-specific federal legislation to be enacted.
Does this rule affect Tether (USDT)?
Yes. The GENIUS Act’s scope covers any stablecoin used by U.S. persons, regardless of where the issuer is based. Tether, incorporated offshore, must either comply with the AML and sanctions rules or face pressure from U.S. exchanges to delist USDT. The January 2027 enforcement deadline is the practical cutoff for compliance decisions.
When will the rules become final?
Treasury must issue final AML and sanctions regulations by July 18, 2026, a deadline written into the GENIUS Act. Full enforcement begins no later than January 18, 2027. A 60-day public comment window is open after the rule’s Federal Register publication.
