"This proposal will protect the U.S. financial system from national security threats without hindering American companies' ability to forge ahead in the payment stablecoin ecosystem." — Scott Bessent, U.S. Secretary of the Treasury
Four federal agencies issued six proposed rules in a ten-day span to implement the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, signed into law on July 18, 2025. The OCC, FDIC, Treasury, FinCEN, and OFAC have collectively produced the most detailed stablecoin regulatory architecture ever attempted by a major economy, covering capital adequacy, reserve composition, redemption windows, AML/CFT obligations, sanctions compliance, and the conditions under which state regulators may retain oversight of smaller issuers.
The rulemaking lands on a $315 billion market where two issuers — Tether and Circle — control 93% of supply. The proposed rules will determine whether banks, fintechs, and foreign issuers can compete on equal footing, or whether the compliance burden entrenches incumbents. Comment periods close between May 1 and June 9, 2026. Final rules are expected by late Q3 2026, nine months before the GENIUS Act's 18-month implementation deadline.
The implementation sprint began with the OCC and accelerated through the first two weeks of April:
| Date | Agency | Action | |------|--------|--------| | Feb. 25, 2026 | OCC | Published proposed rule for federally supervised PPSIs (Bulletin 2026-3) | | April 1, 2026 | Treasury | Released NPRM on state-regime equivalence principles | | April 7, 2026 | FDIC | Board approved NPRM for FDIC-supervised PPSIs and IDIs | | April 8, 2026 | FinCEN/OFAC | Issued joint proposed rule on AML/CFT and sanctions compliance | | April 10, 2026 | FDIC | Federal Register publication (Vol. 91, No. 69) | | April 10, 2026 | FinCEN/OFAC | Federal Register publication of AML/sanctions rule |
Comment deadlines are staggered: the OCC closes May 1, while the FDIC and FinCEN/OFAC windows run to June 9, 2026. Treasury's 60-day window runs from the date of Federal Register publication.
The Federal Reserve Board and National Credit Union Administration have not yet issued their corresponding proposals, leaving gaps in the framework for Fed-supervised bank subsidiaries and credit union issuers.
The OCC's February 25 proposal sets the reference standard that other agencies are calibrating against. It applies to national banks and their subsidiaries, federal savings associations, federal branches of foreign banks, and nonbank entities seeking federal PPSI charters.
Capital. At inception, a permitted payment stablecoin issuer must maintain capital equal to the greater of (a) the amount specified in its OCC approval order or (b) $5 million. Capital must consist of high-quality instruments — common equity tier 1 and additional tier 1 as defined under existing federal banking capital rules.
Reserves. Every stablecoin in circulation requires dollar-for-dollar backing. Eligible reserve assets: U.S. cash, insured bank deposits, short-term Treasury securities, government money market funds, and "any other similarly liquid Federal Government-issued asset approved by the OCC," including tokenized versions of all of the above. Reserves must be held in segregated accounts, separate from the issuer's proprietary funds.
Redemption. Issuers must redeem at par within two business days. A pressure-valve provision allows extension to seven calendar days if redemption demands exceed 10% of outstanding issuance within a 24-hour period.
Interest prohibition. PPSIs may not pay interest or yield for holding, using, or maintaining a payment stablecoin. This provision directly constrains stablecoin-as-savings-product models.
Reporting. Weekly confidential reports on issuance and reserve levels. Monthly public disclosure of reserve composition, examined and attested by a registered public accounting firm.
The FDIC's April 7 proposal is "generally aligned" with the OCC framework, according to Sullivan & Cromwell's analysis, but diverges in consequential areas.
Scope. The FDIC rule applies to PPSIs that are subsidiaries of FDIC-supervised insured depository institutions, as well as to IDIs providing custodial or safekeeping services for payment stablecoins.
Enforcement discretion. The most material divergence concerns what happens when a PPSI fails. The OCC imposes mandatory consequences — automatic triggers when an issuer breaches reserve ratios, capital floors, or faces mass redemptions. The FDIC retains discretionary authority, allowing examiners to tailor responses to circumstances.
Deposit insurance. The FDIC addressed a critical question: deposits held as reserves backing a payment stablecoin are not insured on a pass-through basis to stablecoin holders. This means a stablecoin holder's claim runs through the issuer, not directly to the FDIC. Separately, the agency confirmed that deposit insurance applies to tokenized deposits regardless of the technology used for recordkeeping — a technology-neutral posture matching the Federal Reserve-OCC-FDIC joint FAQ issued March 5, 2026.
Redemption. The FDIC adopted the same two-business-day standard with the seven-day extension trigger.
Treasury's April 1 NPRM addresses the GENIUS Act's dual-track structure: issuers with $10 billion or less in outstanding stablecoins may operate under state supervision if the state's regime is "substantially similar" to the federal framework.
The determination matters. As of April 2026, there are no federally approved state-qualified payment stablecoin issuers. The equivalence test is the gateway.
Treasury's proposal requires state regimes to match federal standards across multiple dimensions:
This framework received 333 public comments during the earlier advance notice of proposed rulemaking phase (September 2025). State regulators consistently emphasized the need for enforcement parity with federal agencies, according to Treasury's summary of comments.
The joint FinCEN/OFAC proposed rule, published in the Federal Register on April 10, applies Bank Secrecy Act obligations to stablecoin issuers for the first time.
Classification. PPSIs are classified as "financial institutions" under the BSA — the same designation applied to banks, broker-dealers, and money services businesses.
AML/CFT program. Each issuer must maintain a compliance program including risk assessments, written policies and procedures, internal controls, independent testing, and ongoing employee training. The structure mirrors what banks have operated under for decades.
Suspicious Activity Reports. PPSIs must file SARs on transactions above $5,000, matching the banking threshold.
Sanctions compliance. Issuers must adopt and maintain an effective sanctions compliance program, a requirement directly mandated by the GENIUS Act's text.
Technology guidance. FinCEN indicated it will issue separate guidance within three years on detecting illicit activity using AI, APIs, digital identity verification, and blockchain analytics. Treasury is seeking public comment on which technologies are most effective.
The Brookings Institution has flagged that the three-year timeline for technology guidance may be too slow given current stablecoin transaction volumes exceeding $1 trillion per month — roughly ten times end-of-2020 levels.
Total stablecoin supply reached $315 billion in Q1 2026, according to market data from DefiLlama and KuCoin Research. The market remains a duopoly: Tether (USDT) at $184.4 billion and Circle (USDC) at $78.6 billion together account for 93% of total capitalization.
The two incumbents face different compliance postures.
Circle has positioned USDC as pre-compliant. Reserves are fully backed and attested by a Big Four accounting firm. Circle's public documentation explicitly maps its practices to GENIUS Act requirements.
Tether launched USAT (USA₮) on January 27, 2026 — a separate, U.S.-regulated stablecoin issued through Anchorage Digital Bank, N.A., an OCC-chartered institution. This structure allows Tether to offer a GENIUS Act-compliant product for U.S. users while maintaining USDT offshore under different terms. USDT itself holds approximately 20% of reserves in non-cash assets including secured loans, Bitcoin, and precious metals, according to Brookings analysis — a composition that may not satisfy the OCC's eligible-asset list.
Bank entry. The FDIC and OCC frameworks open the door for any FDIC-insured bank to apply to issue payment stablecoins through a subsidiary. According to Sullivan & Cromwell's analysis, the first bank-issued stablecoins could appear by late 2026 or early 2027. These would compete directly with USDT and USDC, backed by existing bank deposit infrastructure and customer relationships.
In Q1 2026, USDC added roughly $2 billion in new issuance while USDT shed approximately $3 billion, according to KuCoin data. Whether this shift reflects early regulatory positioning or independent market dynamics is unclear.
The Brookings Institution identified four structural risks in the current framework:
1. Reserve asset fragility. The GENIUS Act permits reserves in uninsured bank deposits. Brookings researchers noted that "uninsured deposits are risky and illiquid, raising the possibility that stablecoins backed by these assets will not offer a stable value." The comparison to 19th-century wildcat banking is explicit in the analysis.
2. Nonfinancial company issuance. The Act allows publicly traded nonfinancial firms to issue stablecoins with unanimous Stablecoin Review Council (SCRC) approval. Privately held companies face no similar prohibition — a gap that requires Congressional action to close. The risk: technology platform operators leveraging proprietary data and network effects to create concentrated payment systems.
3. Foreign issuer arbitrage. Treasury must define "comparable foreign regulations" for issuers serving U.S. residents. If the standard is set too low, foreign-domiciled issuers could undercut domestic compliance costs. If set too high, it could fragment global stablecoin liquidity.
4. Fed and NCUA gaps. The Federal Reserve Board and National Credit Union Administration have not yet issued their proposed rules. Until they do, Fed-supervised bank subsidiaries and credit unions lack a clear pathway to stablecoin issuance. The asymmetry could distort competitive dynamics.
Additionally, the prohibition on paying interest or yield creates tension with the existing stablecoin yield market. An earlier report in this series noted that the White House and banking lobby clashed over this provision during the CLARITY Act negotiations. The prohibition remains in force under the GENIUS Act.
The GENIUS Act rulemaking represents the first attempt by a major economy to regulate stablecoins at the same granularity applied to banks. The framework is detailed, prescriptive, and deliberately anchored to existing prudential standards. Whether it produces a competitive, multi-issuer market or entrenches the Tether-Circle duopoly depends on three variables: the cost of compliance relative to issuer margins, how Treasury defines foreign issuer equivalence, and whether banks view stablecoin issuance as an opportunity worth the capital allocation.
The $315 billion market will not wait for regulators to finish. Final rules are expected by late Q3 2026. Between now and then, every aspiring issuer — bank, fintech, or foreign entrant — is reading 1,200 pages of proposed regulation and calculating whether the economics work.
