The U.S. Treasury is moving the GENIUS Act from legislation into practical market rules.

Its latest proposal clarifies when a payment stablecoin is considered issued in the United States, who counts as being located in the country and when exchanges, custodians and other digital-asset service providers are considered to be offering stablecoins to U.S. customers.

For investors, the important question is increasingly whether a stablecoin can retain legal access to the U.S. market.

Key Overview

• Treasury announced the Section 3 NPRM on August 17.
• Federal Register publication followed on August 18.
• Comments close October 19, 2026.
• January 18, 2027 is the current expected effective-date benchmark.
• Major platform restrictions apply from July 18, 2028.
• State-supervised issuers can potentially use the state pathway when outstanding issuance does not exceed US$10 billion.
• Foreign issuers face additional U.S. market-access requirements.

US Stablecoin Rules Define Who Needs a GENIUS Act License

Stablecoin regulation in the United States is entering a more consequential stage.

The GENIUS Act established the broad framework. Treasury’s new proposal begins defining who actually falls inside it.

The Treasury Section 3 proposal, announced August 17, focuses on when a payment stablecoin is issued in the United States and when it is offered or sold to someone located there.

The proposal was then published August 18 federally, with the 19 October comment deadline giving issuers, exchanges and other market participants time to challenge or refine Treasury’s approach.

For investors, this is where stablecoin regulation starts becoming a competitive issue.

What Counts as U.S. Issuance?

One of Treasury’s most useful proposals is a clearer definition of “issue.”

The rule focuses on the first transfer of a payment stablecoin from the issuer to another person. Importantly, the transfer can occur directly or indirectly and can include crediting an account even when the token remains in a wallet controlled by the issuer.

Treasury would generally treat issuance as occurring in the United States if either the issuer or the recipient is located there at the time of issuance.

That proposed U.S. issuance test matters for offshore structures. Simply minting tokens through infrastructure outside America may not necessarily keep an issuer outside the U.S. regulatory perimeter if those tokens are being issued directly to U.S.-located customers.

Who Is “Located” in America?

Treasury also proposes a practical location test.

For individuals, the rule generally looks at physical presence in the United States, while carving out non-U.S. residents who are only temporarily visiting.

For companies, the test looks at whether the business is organised under U.S. or state law or has its principal place of business in the United States.

That distinction matters because stablecoins travel globally far more easily than traditional bank products.

A U.S. resident travelling abroad and a foreign tourist temporarily visiting America may therefore receive different treatment under the proposed definition.

Foreign Stablecoins Face the Bigger Test

Foreign-issued stablecoins are where the commercial impact could become most visible.

The GENIUS Act gives Section 3 extraterritorial reach when payment stablecoins are offered or sold to people located in the United States.

From the 18 July 2028 milestone, digital-asset service providers generally cannot offer payment stablecoins to U.S.-located customers unless the token comes from a permitted issuer or a qualifying foreign issuer.

Foreign issuers also face requirements around compliance with lawful U.S. orders and reciprocal regulatory arrangements.

The OCC foreign issuer framework additionally provides for supervision and registration of qualifying foreign payment-stablecoin issuers.

This means regulatory access could become a competitive advantage.

Two stablecoins may have similar reserves, technology and liquidity, but the one capable of satisfying U.S. regulatory requirements could have substantially greater access to exchanges, custodians and institutional payment infrastructure.

There Is Still a State Route

Not every domestic stablecoin issuer must necessarily follow exactly the same federal path.

Treasury’s separate state-framework proposal confirms that issuers with no more than the US$10 billion state threshold may potentially opt for state supervision where that regulatory regime is determined to be substantially similar to the federal framework.

This creates a layered system:

Federal supervision for some issuers, qualifying state supervision for others, and a separate route for eligible foreign issuers seeking U.S. access.

Decision tree showing whether a payment stablecoin is issued or offered in the United States, whether the issuer is domestic or foreign, and whether federal licensing, qualifying state supervision or the foreign-issuer pathway applies before U.S. exchanges and other service providers can offer the token.

The Effective Date Needs One Qualification

The expected GENIUS Act start date is January 18, 2027, but investors should not treat that date as completely fixed.

The 18 January 2027 benchmark represents 18 months after the law was enacted.

However, the Act can take effect earlier if the primary federal regulators issue final implementing rules and 120 days subsequently pass.

That makes final rulemaking itself an important catalyst.

What Investors Should Watch

Four issues now matter most:

• How Treasury changes the proposal after comments;
• Which state frameworks qualify;
• How foreign issuers pursue U.S. recognition; and
• Which exchanges and custodians begin adjusting their stablecoin listings before 2028.

This proposal does not license any particular stablecoin.

It also does not mean every foreign stablecoin will be banned, and regulatory compliance does not transform a stablecoin into an FDIC-insured bank deposit.

Conclusion

The GENIUS Act debate is shifting from whether stablecoins should be regulated to which stablecoins can legally reach U.S. customers.

That is a much more important question for investors.

Regulatory access can influence exchange availability, institutional adoption, liquidity and ultimately market share.

Treasury’s latest proposal therefore begins drawing something the stablecoin industry has historically lacked: a clearer boundary between global circulation and lawful access to the U.S. financial market.

FAQs

Does Treasury’s proposal license stablecoins?

No. It establishes proposed definitions and rules for determining when licensing and other GENIUS Act requirements apply. Individual issuers still need the relevant regulatory approvals.

Will foreign stablecoins be banned?

Not automatically. The law provides a route for qualifying foreign issuers, although they must satisfy additional regulatory, lawful-order and reciprocal-arrangement requirements.

Why is July 18, 2028 important?

That is when the broader restriction on digital-asset service providers offering non-qualifying payment stablecoins to people in the United States becomes especially important.

Are regulated stablecoins FDIC insured?

Not automatically. A payment stablecoin is not simply transformed into an insured bank deposit because its issuer is regulated under the GENIUS Act.
