The U.S. Treasury Department published its first Notice of Proposed Rulemaking (NPRM) under Section 3 of the GENIUS Act on August 18, 2026, opening a 60-day comment period that closes October 19. The rule defines when a payment stablecoin is "issued, offered, or sold" in the United States, triggering licensing requirements backed by criminal penalties of up to $1 million and five years in federal prison per violation.
The rulemaking lands on a $308 billion stablecoin market in which two issuers — Tether ($183.4 billion) and Circle ($71.8 billion) — control 82.3% of total supply. For Tether, the rule crystallizes a $47 billion reserve restructuring problem: roughly 25% of USDT reserves sit in gold, Bitcoin, and secured loans that fail the GENIUS Act's narrow list of permitted assets. For Circle, the rule ratifies a regulatory moat the company spent years constructing across 46 state money transmitter licenses, a New York limited purpose trust charter (granted July 31, 2026), and an OCC national trust bank charter (approved July 10, 2026).
This is the third major GENIUS Act rulemaking of 2026, following the OCC's 350-page proposed rule in February and the FDIC's implementing standards in April. All seven mandated agencies missed the statutory July 18 rulemaking deadline. The next hard deadline is January 18, 2027, when stablecoin licensing becomes mandatory.
Treasury's proposed rule addresses three questions the GENIUS Act left to agency discretion: (1) when a stablecoin is considered "issued" in the U.S., (2) when an issuer or service provider is considered to be "offering or selling" a payment stablecoin to a U.S. person, and (3) how foreign issuers access U.S. markets through reciprocity determinations.
The rule does not define reserve composition — the OCC's February NPRM and the FDIC's April proposal already covered that. Instead, Treasury's August rule closes the jurisdictional gap: it determines which entities fall under U.S. law at all.
For domestic issuers, the framework is straightforward. Entities must hold a federal or state license as a Permitted Payment Stablecoin Issuer (PPSI). The OCC, Federal Reserve, and state regulators share supervisory authority under a dual-banking model that the Act preserves.
For foreign issuers, the path is narrower. A foreign-issued stablecoin may be offered or sold in the U.S. only if the Treasury Secretary issues a formal "reciprocity determination" certifying that the foreign jurisdiction's regulatory framework is "substantially similar" to U.S. standards. As of August 2026, no foreign jurisdiction — including El Salvador, where Tether is incorporated — has received that certification.
The GENIUS Act restricts stablecoin reserves to a narrow set of high-quality liquid assets:
Assets explicitly excluded: precious metals, Bitcoin or other cryptocurrencies, corporate debt, equities, and secured loans.
Reserves cannot be rehypothecated, commingled with issuer operating funds, or lent out except for limited purposes specified in the statute. Monthly composition reports must be examined by a registered public accounting firm and certified by the issuer's CEO and CFO. The FDIC's April proposal specified that reserves held as deposits at insured banks would not qualify for FDIC pass-through insurance to stablecoin holders.
One additional constraint: the GENIUS Act prohibits permitted issuers from paying interest or yield to holders simply for holding the coin. This provision limits the product to a payments instrument, not a savings or investment product.
Tether faces two simultaneous compliance challenges under the GENIUS Act framework.
Challenge 1: Reserve Composition. According to Tether's Q1 2026 attestation by BDO Italia, approximately 25% of USDT reserves are invested in assets the GENIUS Act would prohibit. This includes roughly $8 billion in gold, roughly $7 billion in Bitcoin, and additional holdings in secured loans and other non-qualifying instruments. At USDT's current market capitalization of $183.4 billion, that gap represents approximately $47 billion in assets that would need to be liquidated and reinvested in qualifying instruments — primarily short-dated U.S. Treasuries — before USDT could meet the statutory reserve standard.
Challenge 2: Jurisdictional Access. As a foreign issuer incorporated in El Salvador, Tether requires a reciprocity determination from Treasury to legally offer USDT to U.S. persons. That determination has not been issued. No timeline for any reciprocity determination has been published.
Tether's response has been to create a parallel product. On January 27, 2026, the company launched USAT (USA₮), a separate stablecoin issued through Anchorage Digital Bank, an OCC-regulated federally chartered digital asset bank, and custodied through Cantor Fitzgerald. USAT was engineered from inception for GENIUS Act compliance: full reserves in qualifying assets, monthly attestations, and integrated AML/KYC programs.
The strategic question is whether USAT can absorb USDT's U.S. market share before the July 18, 2028, deadline, after which U.S. platforms cannot offer stablecoins from unlicensed issuers. USDT currently holds approximately 59% of total stablecoin supply and 74% of on-chain trading volume, according to CoinMarketCap data.
Circle has pursued the opposite strategy: instead of building a separate product, it has systematically accumulated every license the GENIUS Act framework requires.
On July 10, 2026, the OCC granted final approval for Circle National Trust, a national trust bank authorized for digital asset custody. Three weeks later, on July 31, the New York Department of Financial Services granted Circle a limited purpose trust charter for Circle New York Trust. These approvals sit on top of 46 state money transmitter licenses and a BitLicense that Circle had previously obtained.
This dual-charter structure — federal custody powers paired with state-level USDC issuance oversight — maps directly onto the GENIUS Act's Permitted Payment Stablecoin Issuer framework. USDC's $71.8 billion in reserves already consists almost entirely of qualifying assets: cash held at regulated banks and short-dated Treasury securities held in the Circle Reserve Fund managed by BlackRock.
As Forbes noted in an April 2026 analysis, the compliance burden of the GENIUS Act functions as a barrier to entry that validates Circle's multi-year regulatory investment. Most potential new issuers cannot absorb the cost of BSA/AML compliance, monthly reserve attestations, and dual federal-state licensing.
The GENIUS Act opened stablecoin issuance to banks — and banks are paying attention. According to Forbes, banks are "suddenly targeting" the $323 billion stablecoin market following the Act's passage.
The dual-banking model preserved by the GENIUS Act allows two paths for bank issuers:
The OCC's February 2026 proposed rule — at 350-plus pages — establishes the supervisory standards for the federal path. The FDIC's April rule covers FDIC-supervised institutions. Both rules require a two-business-day redemption window, bankruptcy-remote reserve structures, and compliance with the Bank Secrecy Act.
For traditional banks, the economics are familiar: stablecoins backed by short-dated Treasuries generate yield on reserves while offering customers a digital payments instrument. At current short-term Treasury yields, a bank issuing $10 billion in stablecoins backed by 93-day T-bills could generate approximately $400-500 million in annual interest income on reserves — without paying interest to holders, per the statutory prohibition.
The GENIUS Act's enforcement provisions separate it from prior crypto regulatory efforts by attaching criminal, not just civil, consequences to non-compliance.
Criminal penalties: Anyone who knowingly issues a payment stablecoin without proper licensing faces fines of up to $1 million and up to five years in federal prison per violation.
Civil penalties: Material violations carry civil fines of up to $100,000 per day. Knowing violations incur an additional $100,000 per day. These compound independently.
BSA/AML obligations: In April 2026, Treasury's Financial Crimes Enforcement Network (FinCEN) and the Office of Foreign Assets Control (OFAC) published a joint proposed rule treating Permitted Payment Stablecoin Issuers as financial institutions under the Bank Secrecy Act. This means full suspicious activity reporting (SARs), customer identification programs, and OFAC sanctions screening — the same obligations that apply to banks.
The enforcement framework effectively treats unlicensed stablecoin issuance as equivalent to unlicensed money transmission — a federal crime.

Treasury's August 18 NPRM closes the jurisdictional gap in the GENIUS Act framework by defining when a stablecoin is issued, offered, or sold in the U.S. Comments close October 19, 2026.
Tether faces a $47 billion reserve restructuring to bring USDT into compliance and has received no reciprocity determination from Treasury for its El Salvador jurisdiction. Its parallel product, USAT, issued through Anchorage Digital Bank, is GENIUS-compliant but holds negligible market share relative to USDT.
Circle has completed a dual federal-state licensing structure (OCC national trust bank + NYDFS trust charter) that maps directly onto the GENIUS Act's PPSI framework, positioning USDC as the compliance benchmark.
Criminal penalties — up to $1 million and five years per violation — elevate stablecoin regulation from civil enforcement to criminal law, matching the regime applied to unlicensed money transmission.
The January 18, 2027, mandatory licensing deadline and July 18, 2028, platform exclusion deadline create a two-phase compliance clock for every issuer operating in U.S. markets.
The GENIUS Act's no-interest provision confines payment stablecoins to a payments instrument, foreclosing yield products and narrowing the competitive surface to operational efficiency, trust, and distribution.
The GENIUS Act rulemaking process is now in its third phase. The OCC defined how institutions qualify. The FDIC defined how deposits work. Treasury has now defined who falls under U.S. jurisdiction. What remains is enforcement.
The January 2027 licensing deadline is 148 days away. The July 2028 platform exclusion deadline is 696 days away. Between those two dates, the $308 billion stablecoin market must sort itself into licensed and unlicensed issuers, with U.S. platforms forced to delist the latter.
The data suggests the market is already bifurcating. Circle has built a bank-grade regulatory stack. Tether has built a parallel product. Banks are evaluating entry. The compliance architecture is set. What happens next is arithmetic: which entities can restructure fast enough, and at what cost.
