The GENIUS Act Treasury stablecoin rule comments deadline closes on Monday, October 19, 2026, ending a narrow public window before one of the most consequential regulatory events in the digital asset sector since the spot bitcoin ETF launches of early 2024. Treasury published its notice of proposed rulemaking implementing section 3 of the 2025 stablecoin law under docket TREAS-DO-2026-0496 (RIN 1505-AC95, 91 FR 53368), and ninety-one days after the comment period ends, the statute’s effective date lands on January 18, 2027. Issuers, exchanges, custodians, and foreign platforms that touch US persons have roughly a weekend to file substantive comments on the proposed definition of a permitted payment stablecoin issuer, the framework for federal and state qualified issuers, and the criminal penalties that attach to knowing violations. The rule is on rails in the sense that Congress has already legislated, but Treasury still has meaningful discretion on definitions, certifications, recordkeeping expectations, and the mechanics of the intermediary prohibition that activates on July 18, 2028.
Section 3 of the statute makes it unlawful for anyone other than a permitted payment stablecoin issuer to issue a payment stablecoin in the United States. The statute enumerates three paths to that status: a US-formed subsidiary of an insured depository institution approved under section 5, a federal qualified issuer, or a state qualified issuer. Anyone who knowingly participates in a violation faces a fine of up to one million dollars per violation, up to five years in prison, or both. For an industry in which circulating stablecoin supply has stalled near 305 billion dollars year to date, with only a 0.4 percent gain despite 482 billion dollars of stablecoin payment volume over the first nine months of 2026 per Allium, those criminal exposure figures are not abstract. They reshape underwriting, partnership diligence, and the cost of capital for any non-permitted token.
GENIUS Act Treasury stablecoin rule comments deadline: The intermediary provision in section 3(b)(1) is the part that should keep compliance officers up at night
The intermediary provision in section 3(b)(1) is the part that should keep compliance officers up at night. Beginning July 18, 2028, no digital asset service provider may offer or sell a payment stablecoin to a person in the United States unless a permitted issuer issued it. That language is broad enough to capture exchanges, broker-dealers, OTC desks, payment processors, hosted wallet providers, and potentially decentralized frontend operators that route US customer orders to a non-permitted token. Section 3(b)(2) extends the statute extraterritorially from the Act’s effective date, meaning foreign issuers such as Tether and Paxos-affiliated vehicles, and any offshore white-label arrangement, are pulled into US jurisdiction as soon as the law activates on January 18, 2027. Issuers that want to keep serving US persons will need to apply for permitted issuer status, restructure through a US insured depository subsidiary, or wind down the US leg of their business.
Circle is the obvious test case. USDC circulation sits at roughly 72.5 billion dollars according to the issuer’s own disclosures, and the European Union has already classified USDC as a significant e-money token under MiCA, which is a different but parallel supervisory track. France’s National Assembly has separately approved taxing crypto-to-stablecoin swaps starting in 2027, which raises the practical question of whether MiCA’s significant token regime and the GENIUS Act’s permitted issuer regime can interoperate for a dual-listed issuer. Treasury’s NPRM will need to address how a federal qualified issuer status applies to a token that is already supervised in Brussels, and whether state qualified issuers will be expected to mirror MiCA’s reserve, segregation, and redemption timelines to avoid friction in cross-border clearing.
Meanwhile, the spot bitcoin ETF complex is leaking capital at a pace that contrasts sharply with stablecoin payment growth. This week saw 228.6 million dollars of net outflows, on top of roughly 910 million dollars over the prior two weeks per Decrypt citing SoSoValue, with Wednesday alone printing 261.4 million dollars of redemptions. The worst single day in October was October 7 at 484.9 million dollars of exits, and cumulative net inflows since the January 2024 launch have eased to about 57.3 billion dollars. The macro read is that allocators are rotating from beta exposure into dollar-pegged payment infrastructure just as the regulatory perimeter around that infrastructure hardens. For Tether, Circle, and Paxos, the comment window is therefore the last cheap chance to argue for technical carve-outs on mint and redemption attestations, foreign-issuer equivalence, and the treatment of algorithmic or yield-bearing variants that sit outside the statute’s permitted issuer lanes. The GENIUS Act Treasury stablecoin rule comments deadline will reshape how investors, regulators, and competitors weigh the next round of public-purpose commitments.
Critics may argue that because the statute is already enacted, the NPRM is a formality. That misreads the rulemaking. Treasury can still move definitions of permitted issuer, certification cadence, custodial standards, and the evidentiary weight given to foreign supervision, and each of those choices can swing billions of dollars of token supply into or out of compliant status by 2028. Commenters should focus on the operational record a permitted issuer must keep, the treatment of secondary market liquidity providers that touch non-permitted tokens, and how Treasury will coordinate section 3 with OFAC, BSA, and state money transmission frameworks that have not been preempted. The GENIUS Act Treasury stablecoin rule comments deadline is therefore not a procedural footnote. It is the final docket entry before the US payment stablecoin market moves from a soft supervisory regime to a hard statutory one, and the choices Treasury makes on this NPRM will determine who gets to issue, who gets to intermediate, and who gets to leave the market entirely.
