"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
Three federal agencies issued four proposed rules implementing the GENIUS Act within a ten-day window in April 2026. The Treasury Department published state-equivalency principles on April 1. The FDIC approved prudential standards for bank-affiliated stablecoin issuers on April 7. FinCEN and OFAC released a joint anti-money laundering and sanctions framework on April 8. The combined package appeared in the Federal Register on April 10, triggering 60-day comment periods that close in early June.
The rulemaking wave arrives nine months after President Trump signed the GENIUS Act into law on July 18, 2025 — the first federal statute governing payment stablecoins. Total stablecoin market capitalization reached $318.6 billion as of April 11, 2026, up 38.4% year-over-year from $236 billion. Tether's USDT commands $184.4 billion (57.85% share); Circle's USDC holds $78.6 billion. Private-sector forecasts project the market could reach $500 billion by year-end. The regulatory infrastructure being built this month will determine which issuers can operate within U.S. borders, and under what terms.
The GENIUS Act directed federal regulators to promulgate implementing rules by July 18, 2026 — one year after enactment. Agencies are now meeting that deadline in coordinated fashion:
| Date | Agency | Action | |------|--------|--------| | April 1 | Treasury | NPRM on state-equivalency principles for the $10B threshold | | April 7 | FDIC | Board approval of prudential standards for FDIC-supervised issuers | | April 8 | FinCEN + OFAC | Joint proposed rule on AML/CFT and sanctions compliance | | April 10 | Federal Register | Publication of FDIC rule (Doc. No. 2026-06974); comment periods begin |
The OCC had already published its own proposed rulemaking in the Federal Register on March 2, 2026, covering licensing, reserves, and operational standards for nationally chartered bank issuers. The April burst completes the interagency picture. FDIC Chairman Travis Hill noted the agency posed 144 specific questions to the public, signaling the final rule could differ materially from the proposal.
The FDIC's proposed rule, published April 10 in Federal Register Vol. 91 No. 69, establishes a prudential framework for "permitted payment stablecoin issuers" (PPSIs) that are FDIC-supervised bank subsidiaries. Core requirements:
Reserve mandate. PPSIs must maintain 1:1 reserves in eligible assets — U.S. dollars or equally liquid instruments — at all times. Large issuers holding $25 billion or more in outstanding stablecoins must additionally maintain at least 0.5% of reserve assets (capped at $500 million) in insured deposits or insured credit union shares.
Redemption window. Holders may redeem stablecoins for U.S. dollars within two business days. For redemption requests exceeding 10% of outstanding issuance value within any 24-hour period, the PPSI must notify the FDIC and may request a discretionary extension.
Capital floor. New PPSIs face a $5 million minimum capital requirement for their first three years. Separately, all PPSIs must maintain a liquidity buffer equal to 12 months of total operating expenses, held in highly liquid assets distinct from the 1:1 reserve pool.
Permissible activities. The proposed rule defines what PPSIs can and cannot do. Lending, yield-bearing programs, and financial services outside the Act's express authorizations are not permitted.
The FDIC's framework aligns broadly with the OCC's February proposal but solicits more granular feedback, particularly on capital methodology and pass-through insurance treatment.
The FinCEN-OFAC joint proposed rule, announced April 8, 2026, classifies permitted payment stablecoin issuers as "financial institutions" under the Bank Secrecy Act for the first time. This places stablecoin issuers in the same regulatory category as banks, broker-dealers, and money services businesses for AML/CFT purposes.
Specific obligations under the proposed rule:
Treasury characterized the framework as "modernized BSA requirements designed to minimize unnecessary regulatory burden while assisting law enforcement." The 60-day comment period begins upon Federal Register publication.
The GENIUS Act creates a dual regulatory track that is unusual in U.S. financial regulation. The Treasury's April 1 NPRM establishes principles for determining whether a state-level stablecoin regime is "substantially similar" to the federal framework.
Below $10 billion: Payment stablecoin issuers with consolidated outstanding issuance of $10 billion or less may choose to operate under a state-level regime — provided that regime meets Treasury's similarity standard.
Above $10 billion: Issuers crossing the $10 billion threshold must transition to federal supervision within 360 days, unless the requirement is waived.
Treasury's proposed principles require state regimes to match federal standards in core prudential areas — reserves, redemption, capital, and risk management — while permitting procedural variation in areas such as data formats, report filing timelines, and internal licensing processes.
The Conference of State Bank Supervisors (CSBS) responded by urging Treasury to preserve state authority. CSBS called the proposed certification timelines "unrealistically short" and recommended a streamlined process allowing states to declare intent to regulate and apply for certification when ready. Comments are due by June 2, 2026.
Currently, states including New York (via the NYDFS BitLicense and stablecoin guidance), Wyoming, and Texas have existing stablecoin-adjacent regulatory frameworks. Whether any current state regime qualifies as "substantially similar" under Treasury's principles remains untested.
The FDIC's proposed rule explicitly states that deposits held as reserves backing a payment stablecoin are not insured to stablecoin holders on a pass-through basis. This is a deliberate policy choice, not an oversight.
FDIC Chairman Travis Hill framed the technology's value beyond consumer payments: "Tokenization offers much more than just a shiny version of Zelle or Venmo," he said, pointing to programmability, atomic settlement, and immutability as the primary benefits.
The rule draws a bright line between stablecoins and tokenized deposits. Tokenized deposits — digital representations of traditional bank deposits — retain full FDIC insurance coverage regardless of the technology used to record them. Stablecoins, by contrast, are treated as a distinct product class outside the deposit insurance framework.
This distinction has structural implications. A consumer holding USDC does not have FDIC protection. A consumer holding a tokenized deposit from JPMorgan does. The regulatory architecture forces issuers and users to internalize the difference. For the $318.6 billion stablecoin market, the absence of deposit insurance means that the 1:1 reserve backing and the 2-day redemption window are the primary consumer protection mechanisms.
The GENIUS Act has created a compliance bifurcation in the stablecoin market. USDC, issued by U.S.-based Circle, is positioned as GENIUS Act-compliant. Approximately 86% of surveyed institutional companies now use or hold USDC, versus 68% for USDT, according to industry data.
Tether's flagship USDT, issued from outside U.S. jurisdiction, does not meet GENIUS Act requirements for a U.S.-domiciled, federally or state-qualified issuer. Tether's response: in January 2026, it launched USA₮ (USAT), a new U.S.-based stablecoin issued through Anchorage Digital Bank, specifically designed for GENIUS Act compliance.
The dual-token strategy allows Tether to maintain USDT for offshore markets while competing with Circle domestically through USAT. Through March 2026, USDC posted a $4.5 billion net supply increase while USDT recorded a $2 billion decline, suggesting compliance status is already influencing capital flows.
The January 2027 compliance deadline — the statutory 18-month window from enactment — will force remaining non-compliant issuers to either restructure, exit the U.S. market, or face enforcement action. Final rules are expected by mid-2026, with a 120-day activation period after final publication, potentially accelerating the effective date to late 2026.
The GENIUS Act becomes effective on the earlier of two dates: 18 months after enactment (January 18, 2027) or 120 days after federal regulators issue final implementing rules. Given the current rulemaking pace — OCC proposed in March, FDIC and Treasury in April — final rules could arrive by July 2026. That would set an effective date as early as November 2026.
Key milestones remaining:
| Date | Event | |------|-------| | June 2, 2026 | Comment period closes for Treasury state-equivalency NPRM | | Early June 2026 | Comment periods close for FDIC and FinCEN/OFAC proposals | | July 18, 2026 | Statutory deadline for final implementing regulations | | Nov 2026 – Jan 2027 | Estimated effective date range | | 360 days post-crossing | Transition deadline for state issuers exceeding $10B |
For existing issuers, the 18-month compliance window from enactment provides the outer boundary. For new entrants, the $5 million minimum capital requirement, the 12-month operating expense liquidity buffer, and the AML/CFT program requirements represent significant barriers to entry.
The April 2026 rulemaking wave transforms the GENIUS Act from statute to operating framework. The combined package — prudential standards, AML/CFT obligations, sanctions compliance, and state-equivalency principles — creates a regulatory architecture comparable in complexity to bank charter requirements.
For a $318.6 billion market growing at 38% annually, the stakes are structural. Issuers that cannot meet 1:1 reserve, 2-day redemption, $5 million capital, and BSA compliance requirements by late 2026 will lose access to U.S. markets. The deliberate exclusion of deposit insurance signals that regulators view stablecoins as a distinct product class — not bank deposits in digital form.
The 60-day comment periods closing in June will shape the final rules. The 144 questions posed by the FDIC alone suggest the agency is genuinely soliciting input. Whether the final framework tightens or loosens from the proposal will depend on what Treasury, the FDIC, and FinCEN hear from the roughly 200 issuers, banks, and state regulators now operating in or adjacent to this market.
