US Treasury drafts GENIUS Act stablecoin rules

TLDR

US Treasury has released draft rules to implement the GENIUS Act, spelling out how payment stablecoins can be issued and sold in the United States.

1. The proposal defines who needs a license to issue or offer stablecoins in the US and opens a 60 day public comment period ahead of a January 2027 start date.
2. From 2027 to 2028, stablecoin activity in the US shifts into a fully licensed regime, affecting big issuers, foreign stablecoins, and exchanges that list them.
3. The final shape of the rules will depend on industry feedback and how they interact with broader crypto bills like the CLARITY Act, so there is still meaningful uncertainty.

Deep Dive

1. What Treasury Just Proposed

The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, signed into law in July 2025, is the first federal framework specifically for payment stablecoins. Treasury has now issued a Notice of Proposed Rulemaking (NPRM) that explains how key parts of that law will work in practice, particularly Section 3, which defines when a stablecoin is considered issued, offered, or sold in the United States.

Under the proposal, issuing a payment stablecoin in the US without a federal or qualifying state license becomes unlawful starting 18 January 2027. A second major date is 18 July 2028, after which digital asset service providers (exchanges, brokers, apps) generally cannot offer or sell payment stablecoins to US persons unless they were created by a licensed issuer or a qualifying foreign issuer, as described in detailed Treasury guidance such as the Section 3 proposal.

Treasury has opened a 60 day comment window once the NPRM hits the Federal Register, with dozens of specific questions around scope, extraterritorial reach, and economic impact, as noted in reporting from Bitcoin.com.

2. How This Reshapes Stablecoins and Platforms

The GENIUS Act itself requires payment stablecoins to be fully backed 1:1 by eligible reserves like cash, deposits, and short term US Treasuries, and to meet licensing, disclosure, and compliance standards. The new draft rules clarify that foreign issuers can only reach US users if they maintain controls to avoid US distribution, or meet strict conditions to qualify as foreign issuers that can comply with lawful US orders and reciprocal arrangements, as outlined in Treasurys foreign issuer guidance.

For exchanges and other service providers, listing or selling a stablecoin to US persons becomes a regulated activity. Solicitations, US targeted advertising, responding to purchase inquiries, or helping users bypass location checks are all treated as offering or selling in the US in proposals described by outlets like Decrypt. Large issuers such as USDC and USDT are widely seen as better positioned to adapt, while smaller or offshore projects may lose US access if they cannot meet licensing and compliance costs.

3. What To Watch Next

The rules are still draft. Industry, civil society, and foreign regulators now have a fixed window to push for changes in definitions, foreign issuer treatment, and carve outs for DeFi and technical edge cases (bridges, wrapped tokens, airdrops), all flagged in the NPRM question set.

There is also a timing risk. Agencies already missed an earlier deadline to finalize GENIUS rules, raising the possibility that the law could formally take effect in January 2027 while details are still being ironed out, as cautioned in coverage by Cointelegraph. In parallel, the broader Digital Asset Market Clarity Act, which would govern wider crypto markets, has stalled in the Senate, so GENIUS may effectively become the primary operational framework for US dollar stablecoins for some time.

Conclusion

GENIUS Act implementation is moving from abstract law into concrete licensing and market access rules, and stablecoin businesses now face a clear pivot toward full regulatory status in the US. For crypto users and builders, the key trade off is greater legal certainty and institutional participation versus reduced flexibility and higher compliance hurdles, especially for foreign and niche stablecoins. The next 60 days of comments, and how Treasury responds, will determine whether this framework ends up tightening US stablecoin markets or enabling a larger but more regulated dollar backed ecosystem.
