Payments regulation: Treasury's GENIUS Act Section 3 proposal

Every licensing regime eventually has to answer a deceptively simple question: when exactly do you need a license? For payment stablecoins, the answer starts to take shape in a notice of proposed rulemaking that the Treasury Department released on August 17, 2026. The proposal addresses Section 3 of the Guiding and Establishing National Innovation for U.S. Stablecoins Act, the GENIUS Act, and it is one of the more practical pieces of payments regulation to emerge from the law so far, because it sets out what it means to issue, offer or sell a stablecoin in the United States.

Two dates that set the clock

The proposal anchors its framework to two dates. Beginning January 18, 2027, entities must hold an appropriate federal or state license to issue a payment stablecoin in the United States. Beginning July 18, 2028, digital asset service providers may not offer or sell payment stablecoins to U.S. persons unless the stablecoins were issued by a licensed issuer.

Those dates create a sequence. First, issuance itself comes under licensing. Then, roughly 18 months later, distribution comes under the same discipline, with service providers barred from selling unlicensed stablecoins to U.S. persons.

The GENIUS Act’s real reach may be measured less by who issues stablecoins than by who is allowed to hand them to American customers.

Defining the territory

The proposal’s most important work is definitional. According to Treasury, it defines what it means to “issue a payment stablecoin in the United States,” and what it means to “offer or sell” a stablecoin to persons in the United States. Those definitions determine whether an issuer, particularly one based abroad, needs a U.S. license, and whether a platform serving U.S. customers is affected.

For a global market in which stablecoins are often issued in one jurisdiction and traded through platforms in many others, these definitions are the hinge on which the entire regime turns. Too broad, and foreign activity with only a slight U.S. connection could be swept in. Too narrow, and the licensing requirement could be easy to avoid.

Foreign stablecoins and service providers

The proposal also addresses foreign-issued stablecoins. Treasury said digital asset service providers face restrictions on offering foreign-issued stablecoins unless the foreign issuer can comply with lawful orders in the United States and applicable reciprocal arrangements.

That condition shifts responsibility onto the service providers, such as exchanges and wallet platforms, that make stablecoins available to U.S. users. They would need to assess whether a foreign issuer meets the conditions before offering its token. In practice, that turns platforms into gatekeepers for which stablecoins U.S. customers can access.

Who is affected

Stablecoin issuers planning to serve the U.S. market are the most directly affected, since they need to secure licenses before the January 2027 date. Foreign issuers face a particular question: whether to seek U.S. licensing or to meet the conditions that would allow service providers to continue offering their tokens.

Digital asset service providers face the July 2028 deadline, after which they would need to ensure the payment stablecoins they offer to U.S. persons come from licensed issuers. Payment companies and merchants that accept stablecoins could see the range of available tokens narrow to those that meet the U.S. framework.

The broader payments regulation build-out

Treasury noted that the proposal builds on an advance notice of proposed rulemaking issued in September 2025. It sits alongside other GENIUS Act rulemakings from Treasury and the federal banking agencies covering anti-money-laundering obligations, customer identification and supervisory frameworks. Together, these proposals form the operating manual for the stablecoin market the law envisions.

What to watch

Comments are due 60 days after Federal Register publication and may be submitted through regulations.gov. The most consequential comments are likely to focus on the definitions of issuing and offering in the United States, and on how the foreign-issuer conditions would work in practice.

After the comment period, watch for whether Treasury narrows or broadens the definitions in a final rule, how the agencies coordinate licensing ahead of January 18, 2027, and how service providers prepare for the July 18, 2028 distribution limit. For anyone building payment products on stablecoins, those dates are now the planning horizon.
