From Legislation to Regulation: What the GENIUS Act Required
The Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, signed in early 2026, established the first comprehensive U.S. federal framework for payment stablecoins. The law empowered Treasury, OCC, and FDIC to issue implementing regulations, and gave each agency 180 days to publish proposed rules.
April 2026 marks the arrival of all three sets of NPRMs (Notices of Proposed Rulemaking) inside that window. The proposals do not rewrite the statute — they operationalize it. The questions they answer are practical: What does a qualified reserve look like? What disclosures satisfy the audit requirement? Under what conditions can a state-licensed issuer distribute nationally?
The coordinated timing reflects a deliberate strategy. Publishing three aligned NPRMs simultaneously reduces the risk of regulatory arbitrage between agencies and creates a unified comment period for the industry.
The Dual-Track Architecture
The GENIUS Act’s most consequential design choice was to allow stablecoin issuers to choose between two oversight tracks:
Federal track (OCC charter): A qualified payment stablecoin issuer chartered by the OCC as a national bank or a new “stablecoin bank” designation. Federal oversight; uniform standards across all 50 states; higher compliance burden upfront but single regulator relationship.
State track (state license + Federal Reserve registration): A state-licensed issuer — under state money-transmitter or stablecoin-specific statutes — that registers with the Federal Reserve as a condition of national distribution. Lower initial licensing cost in permissive states; ongoing Federal Reserve supervision as the federal backstop.
The OCC NPRM defines the capital, liquidity, and governance requirements for the federal path. The FDIC proposal addresses deposit-insurance interaction — specifically, what happens to stablecoin holders when a bank-affiliated issuer fails. Treasury’s NPRM addresses state-oversight equivalency: the conditions under which a state licensing regime qualifies for national distribution without separate federal registration.

Reserve and Redemption Rules: The Operational Core
Both tracks must comply with GENIUS Act reserve floors that the NPRMs now define with precision:
- Reserve composition: Minimum 80% must be held in U.S. Treasury securities with maturities under 93 days, or in cash deposits at Federal Reserve Banks. The remaining 20% may include insured bank deposits, money-market funds investing exclusively in treasuries, or overnight repos backed by treasuries.
- Segregation: Reserves must be held in segregated accounts, legally distinct from the issuer’s operating assets. Commingling with commercial banking assets is expressly prohibited.
- Redemption right: Holders must be able to redeem at par (1:1 USD) within one business day of a verified request, with no redemption gates or fees permitted during the initial 12 months of any stablecoin product.
- Monthly attestation: A registered public accounting firm must attest to reserve composition monthly, and attestation reports must be publicly available within five business days of completion.
These floors matter because they are floors, not ceilings. States may impose stricter requirements; the federal track may apply additional capital surcharges for systemically important issuers. But no issuer — state or federal — may fall below these thresholds and distribute nationally.
The Foreign Issuer Problem
The GENIUS Act created a novel market-access condition for foreign stablecoin issuers: to distribute to U.S. residents, a foreign stablecoin must either be issued by a U.S.-chartered entity or operate under a foreign regulatory regime that Treasury certifies as equivalent.
Treasury’s April 2026 NPRM proposes the equivalency certification process. The criteria mirror EU MiCA’s payment token framework — reserve quality, redemption rights, audit standards, and anti-money-laundering controls — but include a “mutual recognition reciprocity” requirement: the foreign jurisdiction must accept U.S.-issued stablecoins on symmetric terms.
In practice, this places large foreign issuers in three camps:
- MiCA-regulated issuers (EU): Well-positioned for equivalency certification given MiCA’s structural similarity to GENIUS Act requirements. EU-issued stablecoins with MiCA licenses are the clearest path to mutual recognition.
- Unregulated offshore issuers: Must either establish a U.S. entity under federal or state charter, or exit the U.S. retail distribution market. The NPRM sets a 12-month transition period.
- Singapore/UAE-regulated issuers: Both jurisdictions have published stablecoin frameworks in 2023-2024. Whether those frameworks meet Treasury’s equivalency criteria is an open question the comment period will likely clarify.
What Issuers, Banks, and Fintechs Must Do
For existing stablecoin issuers, the immediate action is track selection. The 90-day comment window is not a compliance window — the NPRMs are proposals, not final rules. But the structure is unlikely to change materially in final rulemaking, and track selection requires legal entity restructuring, banking relationships, and reserve custody arrangements that take 12-18 months to implement. Starting now is starting on time.
For banks and their affiliates, the FDIC NPRM introduces a new deposit-insurance interaction analysis. Banks issuing or affiliating with stablecoin issuers must assess whether stablecoin liabilities qualify for deposit insurance pass-through to holders, and under what conditions. The OCC NPRM’s capital treatment for stablecoin-related exposures requires immediate model updates.
For foreign providers, the 12-month transition window in the Treasury NPRM is the operative deadline. Equivalency applications require regulators in the home jurisdiction to engage bilaterally with Treasury — a process that takes months before it reaches a certification decision. Foreign issuers serving U.S. residents should begin the equivalency conversation with their home regulator immediately.
The Long-Term Architecture Question
The dual-track design raises a structural question the NPRMs do not resolve: will a two-tier system create a race to the bottom among permissive states? The GENIUS Act’s answer was to require Federal Reserve registration for all national distributors on the state track — providing a federal floor even within the state-licensed path.
The comment period (90 days from Federal Register publication) will surface competing views. Consumer advocates will likely push for stronger redemption protections; industry will push back on the 93-day treasury maturity cap as operationally restrictive. International jurisdictions will scrutinize the reciprocity condition.
Final rules are expected in the first half of 2027, with an 18-month implementation window. The effective compliance date for most requirements is therefore late 2028 — enough time for orderly implementation, but not enough time to defer track selection.
