The U.S. Senate passed S.1582 — the Guiding and Establishing National Innovation for U.S. Stablecoins Act, or GENIUS Act — on June 17, 2025, 68-30. President Biden signed it July 18, 2025, making it Public Law 119-27. Ten months later, federal regulators are in the middle of building the rules that will give the law its practical shape.

The vote margin was the story before the substance became one. Sixty-eight to thirty is not a narrow partisan win; it is the kind of number that arrives when an industry has spent years arguing that the existing absence of rules is itself a systemic risk. The GENIUS Act is the first comprehensive federal stablecoin framework the U.S. has ever had.

What the law requires

The law narrows who can issue a payment stablecoin in the United States to three categories: subsidiaries of insured depository institutions, OCC-chartered nonbank entities (called federal qualified payment stablecoin issuers), and state-licensed issuers whose regimes meet a "substantially similar" standard relative to the federal framework. Anyone outside those categories issuing stablecoins faces civil penalties of up to $100,000 per day and criminal exposure up to $1 million per violation and five years imprisonment.

Issuers must hold reserves on a one-to-one basis with outstanding stablecoins. Eligible reserves are limited to U.S. currency, Treasury bills with remaining maturity of 93 days or less, short-term repo agreements backed by Treasuries, deposits at insured depository institutions, and qualifying money-market funds. Reserve assets cannot be pledged or rehypothecated, with narrow regulatory exceptions for liquidity management. Monthly disclosures of reserve composition are mandatory; issuers above $50 billion in outstanding market capitalization must publish annual audited financials and disclose related-party transactions.

Every stablecoin holder has a statutory right to redeem at par, directly with the issuer. In a bankruptcy, required reserves are excluded from the debtor's estate; stablecoin holders' redemption claims receive superpriority status over all other creditors.

Issuers are treated as financial institutions under the Bank Secrecy Act. That means full AML and KYC obligations: customer identification, enhanced due diligence, suspicious-transaction reporting, and recordkeeping. Technically, issuers must demonstrate the capability to freeze, block, or burn stablecoins on lawful order.

The Federal Reserve and OCC share oversight of large issuers — those above $10 billion in outstanding issuance. State-licensed issuers at or below that threshold can remain under state supervision if their state regime passes Treasury review, but must transition to federal oversight if they grow past it.

Foreign issuers

A foreign stablecoin issuer may access U.S. markets only if Treasury determines that its home jurisdiction imposes "comparable regulation." What that means in practice is not fully defined yet — Treasury's September 2025 advance notice of proposed rulemaking solicited public comment on the comparability standard and as of early 2026 a final rule has not been issued. Non-compliant foreign issuers are barred from U.S. distribution. The Treasury Secretary is authorized to block foreign stablecoin activity that threatens financial integrity, with an obligation to coordinate with issuers before acting when feasible.

The 12-month safe harbor

Entities with applications pending when the law took effect can operate under a safe harbor for up to 12 months, subject to agency discretion. The OCC, FDIC, Federal Reserve, and NCUA each filed proposed rules in early 2026 to operationalize the licensing and prudential framework; those rules govern how the safe harbor applies to applicants under their respective jurisdictions. The OCC's proposed rule, published February 25, 2026, covers application requirements, permissible activities, and reserve management standards for OCC-chartered issuers. The FDIC's proposed rule followed on April 10, 2026.

Where implementation stands

Regulators have one year from enactment — until July 18, 2026 — to finalize implementing regulations. That deadline is now three months out. The rules under active development cover capital requirements, liquidity standards, reserve diversification parameters, and operational risk management frameworks. The pace of proposed rulemaking across four agencies in roughly the same quarter suggests the deadline is being taken seriously, though final rules on Treasury's comparability determination for foreign issuers remain open.

GENIUS Act vs. MiCA

The structural contrast with the EU's Markets in Crypto-Assets Regulation is instructive. MiCA is a broad framework covering all crypto-assets — it handles stablecoins through two categories (e-money tokens and asset-referenced tokens) but also governs utility tokens, crypto-asset service providers, and market-abuse rules for the whole sector. The GENIUS Act is stablecoin-only: it makes no attempt to regulate the broader digital-asset market, leaving that work to other legislation. MiCA operates through a single harmonized authorization regime that applies identically across all EU member states; the GENIUS Act runs a tiered federal-state system where states retain authority over smaller issuers under Treasury-certified regimes. Both frameworks require one-to-one reserve backing and redemption rights, but MiCA's approach to consumer protection is embedded in ex-ante authorization and disclosure standards, while the GENIUS Act relies more heavily on supervisory enforcement authority and statutory penalties.

The more practically significant gap is scope. A GENIUS Act issuer is licensed to issue stablecoins. A MiCA-compliant entity may be authorized across a much wider range of services under the same regulatory umbrella. Whether that narrowness is a feature — keeping stablecoin rules clean and unburdened — or a gap requiring future legislation is the question U.S. policymakers will face once implementation rules are final.
