Treasury’s Stablecoin Rule Puts New Compliance Burden on Exchanges, Brokers, and Wallets
The U.S. Treasury’s proposed stablecoin rule, published in the Federal Register on August 18, is widely described as a licensing framework for issuers. That characterization misses the provision that will force operational changes at exchanges, brokers, and wallet providers. Proposed §1523.3 would prohibit any digital asset service provider from offering or selling a payment stablecoin to a U.S. person unless the token was issued by a permitted issuer. The issuer must get licensed; the platform must verify.
The Notice of Proposed Rulemaking (NPRM), docket TREAS-DO-2026-0496, implements Section 3 of the GENIUS Act and would create a new 12 CFR part 1523. Comments are due October 19, 2026. The distributor prohibition would take effect July 18, 2028, while the statutory licensing requirement for issuers begins January 18, 2027. On the same day, the Financial Accounting Standards Board (FASB) published an exposure draft proposing a stricter cash-equivalent test for stablecoins under ASC Topic 230, with comments due November 19.

What the NPRM Actually Requires
The NPRM is structured around three operative sections. Proposed §1523.2 addresses issuance. Proposed §1523.3 addresses offer and sale. Proposed §1523.4 creates safe harbors for pending applications, unusual-and-exigent-circumstances relief, and de minimis transactions. Statutory exemptions cover peer-to-peer transfers, cross-border transfers between accounts with the same parent entity, and software self-custody wallets. Everything else — including the exchange, broker, or custodial wallet that routes a payment stablecoin to a U.S. person — falls within §1523.3’s scope.
The NPRM defines “located in the United States” as individuals physically present in the U.S. (excluding temporary non-residents) and entities incorporated in a U.S. state or with a principal place of business here. It contains 43 numbered questions soliciting comment on how these definitions and obligations should be refined. Notably, none of those questions addresses yield directly; the GENIUS Act’s prohibition on issuers paying interest is carried through as a statutory bar, not a subject of rulemaking.
Foreign issuers face separate requirements under Section 18(a): they must be regulated under a comparable foreign regime, register with the OCC, and demonstrate technological capability to comply with U.S. lawful orders. The NPRM includes immediate restrictions on foreign-issued stablecoins whose issuers cannot demonstrate that capability when the rule takes effect. How Treasury will define or test that “technological capability” remains an open question the NPRM poses but does not answer.
Penalties under Section 3(f) of the GENIUS Act reach up to $1 million per violation and up to five years’ imprisonment for knowing participation in unlawful issuance. Treasury Secretary Scott Bessent said in a statement accompanying the release that Treasury welcomes stakeholder input.
The Distributor Problem
The practical weight of §1523.3 falls on platforms, not just issuers. An exchange or broker listing a payment stablecoin will need a mechanism to verify that the token’s issuer holds permitted-issuer status before selling to a U.S. person. But the NPRM does not specify what type of mechanism is required, what documentation would constitute adequate diligence, or how platforms should perform the check.
The 18-month gap between the issuer licensing effective date (January 18, 2027) and the distributor prohibition (July 18, 2028) appears intentional, giving permitted issuers time to establish themselves before platforms must check. Yet the NPRM leaves the operational details unresolved. The American Bankers Association has separately urged Congress, in the context of the CLARITY Act, to tighten language around distribution-fee arrangements that route reserve income to holders through exchanges in ways that functionally resemble yield without technically being issuer-paid interest. The GENIUS Act’s yield prohibition is at the issuer level; whether a distribution fee paid by an issuer to an exchange, which then passes value to holders, violates the spirit of that prohibition is a question the NPRM does not resolve.
Ethena’s USDe, which does pay a yield, is explicitly not a payment stablecoin under the GENIUS Act’s definition. Its supply stood at $4.038 billion as of August 20, per DefiLlama.
FASB’s Test Is Stricter
The accounting question is separate from the regulatory question, and the FASB exposure draft draws a harder line. FASB’s proposed three-part test for treating a stablecoin as a cash equivalent under ASC Topic 230 requires:
- An on-demand contractual right to redeem with the issuer for a known amount of cash.
- The issuer holds at least 1:1 reserves in segregated accounts of short-term, highly liquid assets.
- Secondary-market liquidity cannot substitute for a direct redemption right.
FASB Chair Richard Jones summarized it as three questions: whether you have a right to cash, whether it is on demand, and what backs that right. The third condition is the one that cuts. A stablecoin that trades at par on secondary markets but lacks a direct contractual redemption right with the issuer would fail the test, regardless of its market liquidity. FASB said it was adding illustrative examples to ASC Topic 230 after preparers reported divergent treatment. The exposure draft also requires filers to disclose the significant components of cash equivalents and their amounts.
Where the Market Sits
As of August 20, DefiLlama showed a total stablecoin market cap of $300.94 billion. USDT accounted for $182.997 billion, about 60.81% of the market. USDC stood at $71.967 billion, followed by USDS at $6.713 billion, DAI at $4.767 billion, USDe at $4.038 billion, PYUSD at $2.758 billion, and RLUSD at $1.761 billion. Visa Onchain Analytics reported a record $1.79 trillion in adjusted stablecoin volume for June 2026, with USDC at roughly 67% of that volume.
Circle reported Q2 2026 results on August 5: revenue and reserve income of $701 million (up 7% year over year), net income from continuing operations of $48 million, adjusted EBITDA of $143 million (up 8%), USDC in circulation of $73.3 billion (up 19%), and on-chain USDC transaction volume of $14.8 trillion (up 151%). Distribution, transaction, and other costs totaled $412 million (up 1%). Circle raised its 2026 other-revenue guidance to $310–330 million and disclosed an Arc public mainnet launch date of September 16, 2026. The OCC granted Circle final approval on July 10 to establish First National Digital Currency Bank, N.A. — though that national trust bank charter is distinct from GENIUS Act-permitted payment stablecoin issuer status, which remains a separate determination.
Tether’s Q2 2026 attestation, prepared by BDO on July 31, reported total reserves of $187.75 billion against roughly $184.6 billion of USDT outstanding. The attestation is not an audit. It disclosed that excess reserves fell from roughly $8.23 billion to roughly $4.11 billion quarter over quarter, and that non-cash reserve assets included roughly 146.2 tonnes of gold (valued at approximately $18.83 billion) and roughly 98,933 BTC (valued at approximately $5.80 billion).
The Regulatory Stack
The NPRM is one layer of a regulatory stack that is not yet complete. The OCC’s GENIUS Act implementation proposal runs to a reported 376 pages and has been out for comment since February 2026. Comptroller Jonathan Gould said on August 19 at SALT that the OCC was “intent on moving quickly” and targeted a final OCC rule by November 2026 so that applications could be processed “within the new year.” The Federal Reserve Board’s GENIUS Act rule remained outstanding as of August 20.
The GENIUS Act was signed July 18, 2025. Implementing rules were statutorily due July 18, 2026 — a deadline that passed. The Act’s core effective date is January 18, 2027. In December 2025, the OCC issued conditional national trust bank approvals to BitGo, Fidelity Digital Assets, Paxos, and Circle. Pending applicants include Bridge National Trust Bank, Laser Digital National Trust Bank (a Nomura affiliate), and Morgan Stanley Digital Trust. Again: a national trust bank charter is not the same thing as permitted payment stablecoin issuer status under the GENIUS Act.
The Senate did not vote on the CLARITY Act before its summer recess; action is expected when it returns in September 2026. A Tillis–Alsobrooks compromise on stablecoin rewards was reported in May 2026.
Key dates to track:
- September 2026 — Senate returns; CLARITY Act action expected.
- October 19, 2026 — Treasury NPRM comment deadline.
- November 2026 — Comptroller Gould’s OCC final-rule target.
- November 19, 2026 — FASB exposure draft comment deadline.
- January 18, 2027 — GENIUS Act issuer licensing effective date.
- July 18, 2028 — §1523.3 distributor prohibition effective date.
The question the NPRM’s 43 questions don’t fully answer is the operational one: when July 2028 arrives, exactly how an exchange is supposed to confirm that a token’s issuer is a permitted issuer — and what happens to the roughly $183 billion in USDT if Tether isn’t one.
