Meta description: The GENIUS Act’s AML and sanctions compliance rulemaking comment period closes June 9, 2026. What stablecoin issuers must know before the deadline.
Focus keyword: GENIUS Act AML stablecoin regulation 2026
The comment window for the US Treasury’s proposed anti-money laundering and sanctions compliance rules under the GENIUS Act closes on 9 June 2026 — less than two weeks away. For stablecoin issuers, compliance teams, and the broader digital payments industry, the deadline represents the last formal opportunity to shape regulations that could define how payment stablecoins are monitored and policed for years.
The proposed rules, published in the Federal Register on 10 April 2026, were developed jointly by the Financial Crimes Enforcement Network (FinCEN) and the Office of Foreign Assets Control (OFAC). They represent the first major regulatory implementing action under the GENIUS Act, which became law in 2025 and established the first comprehensive federal framework for payment stablecoins in the United States.
What the GENIUS Act PPSI Rules Propose
The proposed rules establish a mandatory anti-money laundering and sanctions compliance programme framework for a new category of regulated entity: the Permitted Payment Stablecoin Issuer (PPSI).
Under the proposal, PPSIs would be required to:
- Implement a formal AML/CFT programme — including a risk assessment process, transaction monitoring, suspicious activity reporting (SAR), and customer due diligence protocols broadly equivalent to those required of banks.
- Comply with OFAC sanctions screening — with a notable provision that defines “account” to include blockchain wallet addresses for the purpose of lawful order compliance. This means PPSIs would be required to screen wallet addresses against OFAC’s sanctions lists in addition to traditional identity-based checks.
- Submit to FinCEN oversight — treating PPSIs as financial institutions under the Bank Secrecy Act for all relevant regulatory purposes.
The rules also contain nearly 60 specific questions on which FinCEN and OFAC are soliciting public feedback. The questions cover topics including how to handle peer-to-peer transactions on decentralised protocols, how to treat privacy-preserving wallet technologies, and whether existing bank AML programme requirements are appropriate for stablecoin issuers given the differences in business model.
The Wallet Address Provision: Industry’s Biggest Concern
Of all the provisions in the proposed rules, the expansion of the definition of “account” to include wallet addresses has generated the most intense industry pushback in the weeks since publication.
Traditional financial institutions screen customers against OFAC lists using identity data — names, passport numbers, date of birth. Screening wallet addresses against OFAC’s SDN (Specially Designated Nationals) list is conceptually straightforward for known addresses, but it raises hard questions about what happens when funds move through mixing services, privacy protocols, or chains of intermediate wallets.
“The wallet address provision has broad implications that weren’t fully thought through,” said one compliance officer at a major stablecoin issuer, speaking on condition of anonymity. “What does it mean to screen a wallet address at the protocol level? Who bears the liability if USDC ends up in a sanctioned address through three hops of DeFi routing?”
TRM Labs, a blockchain analytics firm, described the provision in its analysis as potentially requiring “real-time on-chain screening” of transaction counterparties — a technical and operational challenge that goes well beyond what traditional AML programmes require.
What Stablecoin Issuers Must Decide Before June 9
The comment window is not just a formality. Final rules almost always reflect substantive input from comment letters, particularly on highly technical questions where regulators acknowledge uncertainty — as FinCEN and OFAC explicitly have here.
Compliance and legal teams at stablecoin issuers have several strategic decisions to make before the deadline.
Should they comment? Choosing not to comment waives the opportunity to have concerns formally entered into the rulemaking record. Courts reviewing regulatory actions often consider whether affected parties raised issues during the comment period.
What to address? The most impactful comment letters will engage the 60 specific questions FinCEN and OFAC posed, particularly on wallet address screening methodologies, treatment of decentralised protocols, and the distinction between custodial and non-custodial issuers.
Coalition or solo? Several industry groups including the Digital Chamber, the Blockchain Association, and the Payment Stablecoin Consortium are expected to file joint comments. Individual issuers must decide whether to join those efforts or supplement them with their own more specific filings.
Timeline After June 9
The comment period closing does not produce immediate rules. FinCEN and OFAC will review submitted comments — potentially numbering in the thousands given the market interest — and publish a final rule, likely later in 2026.
Gibson Dunn’s analysis of the GENIUS Act notes that the Act directs most regulations to be promulgated by 18 July 2026, one year following the Act’s enactment. That timeline is tight, and it is possible that the AML/sanctions programme rules — which require more detailed policy work than some other GENIUS Act implementing regulations — could slip into Q4 2026.
Implementation deadlines will be set in the final rule text. Compliance teams should not assume they have until the publication of the final rule to begin preparing — FinCEN has historically allowed relatively short implementation windows for rules where a proposed rule gave adequate advance notice.
The Bigger Picture: Stablecoin Compliance Grows Up
The GENIUS Act AML rules are part of a broader maturation of the stablecoin industry. Tether and Circle together process hundreds of billions of dollars in transfer volume annually. Payment integrations with Visa, Mastercard, and major remittance networks have brought stablecoins into mainstream commerce in ways that were still theoretical two years ago.
With scale comes scrutiny. The GENIUS Act framework is, for better or worse, the US government’s answer to the question of how you regulate something that moves money globally, instantly, and pseudonymously at near-zero cost.
For issuers that have invested in compliance infrastructure, the incoming rules represent a competitive moat — a barrier that smaller or less sophisticated competitors will struggle to clear. For those that have not, June 9 is a deadline worth taking seriously.

What is the June 9, 2026 deadline?
June 9 is the deadline to submit public comments on FinCEN and OFAC’s proposed rules implementing the GENIUS Act’s AML and sanctions compliance programme requirements for Permitted Payment Stablecoin Issuers.
Who needs to comply with GENIUS Act AML rules?
Any entity classified as a Permitted Payment Stablecoin Issuer under the GENIUS Act framework will be subject to the final rules. This includes major stablecoin issuers such as Circle (USDC) and Tether (USDT) that operate in the US market.
