"President Trump and Congress delivered the GENIUS Act, establishing a landmark framework and clear rules of the road for payment stablecoins, and Treasury is moving quickly to implement that framework." — Scott Bessent, U.S. Secretary of the Treasury
The U.S. Department of the Treasury on August 17 published its first Notice of Proposed Rulemaking (NPRM) under Section 3 of the GENIUS Act, the federal law governing payment stablecoin issuance signed on July 18, 2025. The rule defines when a payment stablecoin is issued, offered, or sold in the United States, carries criminal penalties of up to $1 million in fines and five years imprisonment, and asserts extraterritorial jurisdiction over foreign tokens marketed to U.S. persons. Public comments close October 19.
The rulemaking arrives as the stablecoin market stands at approximately $308 billion in total capitalization, with two issuers — Tether ($186.4B USDT) and Circle ($74.9B USDC) — controlling 83% of supply. The January 18, 2027 licensing deadline and the July 18, 2028 enforcement cliff for digital asset service providers create a compliance timeline that will reshape the competitive landscape. Thirteen companies have already filed for OCC national trust bank charters in 83 days, and Tether has launched a parallel U.S.-compliant stablecoin (USAT) through Anchorage Digital while its $186 billion flagship token still lacks the Treasury reciprocity determination required for foreign issuer status.
The NPRM, published in the Federal Register on August 18, 2026 (Document No. 2026-16796), implements Section 3 of the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act. The core prohibition: it is unlawful for any person to issue a payment stablecoin in the United States unless that person is a permitted payment stablecoin issuer or a qualifying foreign issuer under Section 18(a).
The rule covers three categories of activity:
Permitted issuers must hold a federal or state license. Reserves must be maintained one-to-one in U.S. dollars or equivalent liquid assets, with monthly public disclosures. The FDIC has separately proposed its own implementation rules (published April 10, 2026), and BSA/sanctions compliance standards for FDIC-supervised issuers were proposed on June 5.
The 60-day comment window closes October 19, 2026. Treasury will then review responses before issuing a final rule — a process expected to take several additional months.
The GENIUS Act creates a staged enforcement timeline:
January 18, 2027 — Issuer Licensing Deadline. Eighteen months after enactment, issuing a payment stablecoin to U.S. persons without a permit becomes unlawful. This applies to new issuance; tokens already in circulation are not retroactively affected.
July 18, 2028 — Service Provider Enforcement Cliff. Three years after enactment, digital asset service providers — exchanges, wallets, on-ramps, payment processors — may not offer, sell, or otherwise make available any payment stablecoin not issued by a permitted issuer or a properly registered foreign issuer. This is the harder deadline. It means that by mid-2028, exchanges and platforms must delist or block access to any non-compliant stablecoin, regardless of market cap or liquidity.
Violations carry fines up to $1 million and prison terms up to five years.
The gap between the two deadlines creates an 18-month window during which tokens can circulate but new issuance is restricted. Platforms need contingency plans by Q4 2026 — either confirmed compliance paths for the stablecoins they support, or migration strategies toward qualified alternatives.
The compliance countdown has triggered an unprecedented wave of federal banking applications. According to FinTech Weekly, thirteen companies filed for OCC national trust bank charters within 83 days of the application window opening.
In December 2025, the OCC conditionally approved five applications:
| Applicant | Type | Status | |---|---|---| | Circle (First National Digital Currency Bank) | De novo | Conditionally approved Dec 2025; full approval mid-2026 | | Ripple National Trust Bank | De novo | Conditionally approved Dec 2025 | | BitGo Bank & Trust, N.A. | State-to-national conversion | Conditionally approved Dec 2025 | | Fidelity Digital Assets, N.A. | State-to-national conversion | Conditionally approved Dec 2025 | | Paxos Trust Company, N.A. | State-to-national conversion | Conditionally approved Dec 2025 |
February 2026 brought three more conditional approvals: Bridge (Stripe's stablecoin infrastructure subsidiary), Protego, and Crypto.com. Additional filers include Morgan Stanley, Payoneer, Zerohash, and Dakota (which applied in 2026 after launching a stablecoin offering in January).
An OCC rule change effective April 1, 2026 clarified that national trust banks can hold assets in nonfiduciary custody accounts, further accelerating applications. Sony also received conditional approval for a trust bank charter.
The volume of applications represents a structural shift: stablecoin issuers and crypto infrastructure companies are converting into regulated banking entities. According to Duke University's FinReg Blog, the pace raises questions about supervisory capacity and systemic risk if multiple new trust banks enter the financial system simultaneously.
Tether occupies 59.2% of the stablecoin market at $186.4 billion in USDT supply. Its compliance position under the GENIUS Act is the single largest variable in stablecoin market structure.
The reciprocity gap. Tether is incorporated in El Salvador. Under Section 18 of the GENIUS Act, foreign issuers require a Treasury reciprocity determination — a formal certification that the foreign jurisdiction's stablecoin regulations meet U.S. standards. As of the latest available reports, no foreign jurisdiction has received that determination. Until El Salvador (or any jurisdiction where Tether operates) receives one, USDT cannot qualify as a foreign-issued payment stablecoin eligible for U.S. market access.
The reserve question. According to TechTimes, approximately 25% of Tether's reserve composition — roughly $47 billion — would need restructuring before USDT could satisfy the Act's requirements for dollar-equivalent liquid assets. The Act requires reserves in U.S. dollars, Treasury bills, or equivalently liquid instruments, with monthly public disclosures.
The USAT hedge. Tether launched USAT on January 27, 2026, in partnership with Anchorage Digital Bank, N.A. — the first federally chartered bank to issue a Tether-affiliated stablecoin. USAT is designed for GENIUS Act compliance from inception, with reserves held in cash and short-duration Treasury instruments at Cantor Fitzgerald. As of May 2026, USAT's market cap was $140.8 million — a 500% monthly growth rate, but still less than 0.1% of USDT's capitalization. For context, Circle's USDC sits at $76 billion, PayPal's PYUSD at $5.5 billion, and Ripple's RLUSD at $1.7 billion.
The math is straightforward: Tether has built a compliant product, but migrating even a fraction of USDT's $186 billion market cap into USAT before the 2028 enforcement cliff requires a pace of adoption that has no precedent in stablecoin markets.
Circle has positioned USDC as the regulatory-native stablecoin. Its reserves sit in U.S. dollars and short-dated Treasury bills, custodied at BNY Mellon and managed by BlackRock. Circle received full OCC charter approval in mid-2026 after seven months under conditional status.
The GENIUS Act validates Circle's strategic bet on regulatory compliance. USDC already meets the Act's reserve, disclosure, and licensing requirements. While USDT dominates stablecoin supply at 59% versus USDC's 24%, USDC leads in annual transaction volume: $18.3 trillion versus USDT's $13.3 trillion in 2025, according to stablecoin market data. This volume-supply divergence suggests institutional and payment use cases already favor USDC.
The 2028 enforcement cliff could accelerate this dynamic. If USDT remains unable to qualify under the foreign issuer pathway, U.S.-facing platforms will need to migrate stablecoin pairs toward compliant alternatives. USDC, PYUSD, and RLUSD are the primary beneficiaries of such a shift.
Section 18 of the GENIUS Act provides a narrow exception for foreign-issued stablecoins, but the requirements are stringent:
The proposed rule asserts extraterritorial effect: Section 3's prohibitions apply to any conduct involving the offer or sale of a payment stablecoin to a person located in the United States, regardless of where the issuer is domiciled. This means foreign exchanges and platforms serving U.S. users cannot offer non-compliant stablecoins after the enforcement cliff.
Treasury may establish "reciprocal arrangements" with qualifying jurisdictions, but the mechanism for doing so is still undefined. No reciprocity determinations have been issued to date.
The GENIUS Act rulemaking reshapes stablecoin economics along several axes:
Consolidation pressure. The licensing, reserve, and disclosure requirements create fixed compliance costs that favor large issuers. Of the 382 stablecoins currently tracked across the $314.7 billion market, the vast majority lack the infrastructure to meet federal licensing requirements. Market concentration — already at 83% for the top two issuers — is likely to increase.
Bank-crypto convergence. Thirteen OCC charter applications in 83 days signals that stablecoin issuance is converging with traditional banking. The entry of Morgan Stanley, Fidelity, and Sony into the charter queue indicates that the line between stablecoin issuer and bank is disappearing. The GENIUS Act explicitly states that payment stablecoins are not deposits and are not subject to FDIC insurance — but the issuers themselves are increasingly banking entities.
Exchange compliance costs. U.S. exchanges and platforms must audit every stablecoin they list for GENIUS Act compliance before July 2028. Non-compliant tokens face delisting. This creates operational overhead but also a competitive moat for platforms that complete compliance assessments early.
Dollar hegemony instrument. The extraterritorial provisions, combined with the reserve requirement for U.S. dollar or equivalent assets, effectively extend the dollar's reach through stablecoin infrastructure. Every compliant stablecoin, regardless of issuer nationality, must be backed by dollar-denominated reserves. Secretary Bessent stated the framework aims to "cement the role of the U.S. dollar as the world's reserve currency."
The Treasury's NPRM converts the GENIUS Act from statute to operational regulation. The 60-day comment period will surface industry objections — likely around the extraterritorial scope, the reciprocity mechanism's opacity, and the timeline compression for the January 2027 deadline. But the structural direction is set: the United States is building a licensing regime for stablecoin issuance that treats issuers as quasi-banking entities, requires dollar-denominated reserves, and extends its regulatory reach to any token marketed to U.S. persons.
The market implications are concentrated in two areas. First, the Tether question: whether $186 billion in USDT can find a compliance pathway before the 2028 cliff, or whether market share migrates to licensed alternatives. Second, the consolidation question: whether the compliance costs embedded in the GENIUS Act framework will reduce the 382-stablecoin market to a handful of federally supervised issuers. The comment period closes October 19. The charter race continues.
