The GENIUS Act is the first US federal law governing payment stablecoins. Signed by President Trump on July 18, 2025 as S.1582 in the 119th Congress, it sets who can issue a dollar-pegged stablecoin, how reserves must be held, and what issuers can and cannot pay holders. For anyone who holds, builds with, or routes stablecoins, it converts a patchwork of state money-transmitter rules into one federal standard.

This explainer is written for stablecoin operators and builders, not lawyers. What follows is what the GENIUS Act changes in practice: which tokens count as "payment stablecoins," what it means for USDC, USDT, and PYUSD, the yield prohibition that reshapes product design, the three issuer tiers, and how the US rules line up against the EU's MiCA.

The GENIUS Act, formally the Guiding and Establishing National Innovation for U.S. Stablecoins Act, is a 2025 federal law that creates a licensing and reserve framework for "payment stablecoins." A payment stablecoin is a digital asset an issuer must redeem at a fixed value, used for payment or settlement. The law makes only approved issuers legal in the US.
​

President Trump signed S.1582 into law on July 18, 2025, one day after the House passed it, according to the White House signing record. The bill text and legislative history are tracked on congress.gov under S.1582, 119th Congress. It is the first time the United States has defined a payment stablecoin in statute and assigned federal supervisors to the issuers behind tokens like USDC, PYUSD, and USDG.
​

The practical effect is jurisdictional clarity. Before the Act, a stablecoin issuer operated under a quilt of state money-transmitter licenses with no single federal definition of the product. The GENIUS Act replaces that with a national category, a reserve standard, and a named regulator for each tier of issuer.
​

The GENIUS Act requires payment stablecoins to be backed one-to-one by high-quality liquid reserves, publicly disclosed every month, and examined by an independent accounting firm. Permitted reserve assets are limited to items like US dollars, demand deposits, short-term Treasury bills, and Treasury-backed repos. Riskier holdings such as corporate debt or equities are excluded.
​

The reserve rule is the core of the law. Issuers must hold reserves equal to at least the par value of stablecoins in circulation, in the narrow set of low-risk instruments the statute permits. The Latham & Watkins summary of the GENIUS Act details the permitted-asset list and the prohibition on rehypothecating reserves except in limited cases.
​

Disclosure runs monthly, not quarterly. Issuers must publish the composition of their reserves on their website each month, and the attestation must be examined by a registered public accounting firm. The CEO and CFO of the issuing entity certify those reports. Covington's breakdown of the key provisions lays out the certification and examination cadence.
​

Issuers also carry illicit-finance duties. The Act treats a permitted payment stablecoin issuer as a "financial institution" under the Bank Secrecy Act, which pulls in anti-money-laundering programs, customer-identification duties, and a mandated sanctions-compliance program. FinCEN and OFAC published proposed AML and sanctions rules in April 2026, summarized by Holland & Knight. For a builder, that means an issuer partner now has board-approved AML controls and a US-based compliance officer, not just a transparency page.
​

Three classes of entity can issue a payment stablecoin under the GENIUS Act: a subsidiary of an insured depository institution, a federally qualified nonbank issuer supervised by the Office of the Comptroller of the Currency (OCC), or a state-qualified issuer. State-qualified issuers can operate only while their outstanding issuance stays under a $10 billion threshold.
​

The tiering is the law's most consequential design choice for operators. Bank subsidiaries issue under their bank's prudential regulator. Nonbank issuers that want to scale nationally apply for an OCC charter and sit under federal supervision. State-qualified issuers run under an approved state regime, which the Treasury NPRM on state oversight requires to be "substantially similar" to the federal standard.
​

The $10 billion ceiling is a hard gate, not a guideline. A state-qualified nonbank issuer whose circulation crosses $10 billion must transition to the OCC framework, or stop issuing new stablecoins until its outstanding supply falls back under the line, within a set transition window. The OCC can grant a waiver in limited cases. For context, several leading stablecoins already sit far above that mark: USDT was around $189B and USDC around $77B as of Q1 2026 per DeFiLlama, so any domestic issuer at that scale lands under federal, not state, supervision.
​

Foreign-issued stablecoins are handled separately. Treasury must determine whether a foreign regime is comparable before an offshore token can be broadly offered to US persons through regulated venues. The Yale Journal on Regulation analysis of foreign issuers walks through the equivalency mechanism and the gaps critics have flagged.
​

Yes. The GENIUS Act prohibits a permitted issuer from paying any form of interest or yield to holders based solely on holding the stablecoin, whether paid in cash, tokens, or other consideration. The point of a payment stablecoin under the law is settlement, not return. Yield-bearing products must come from a separate, distinctly regulated wrapper, not the payment token itself.
​

This is the provision that most reshapes product roadmaps. An issuer earns the reserve yield, typically Treasury-bill income, but cannot pass it to holders as a feature of the coin. The State Street Global Advisors explainer notes the prohibition covers yield in "any form," closing the door on rebate-style and points-style workarounds tied to balance.
​

For builders, the design consequence is a clean split. Payment stablecoins become neutral settlement rails. Anything that returns value to a user, tokenized money-market funds, lending positions, or staking-style products, lives in a different legal box with its own disclosures. That separation is why yield-bearing tokens such as Ondo's USDY or BlackRock's BUIDL are structured and marketed apart from payment stablecoins like USDC and PYUSD.
​

The GENIUS Act takes effect on the earlier of two dates: 18 months after enactment, which is January 18, 2027, or 120 days after the primary federal stablecoin regulators issue final implementing rules. Regulators have until roughly July 2026, one year after enactment, to complete most required rulemakings. The window between signing and effect is the implementation runway operators are using now.
​

The dual trigger matters because rulemaking, not the signing date, sets the real clock. If final rules land early, the 120-day path can pull the effective date forward; if rulemaking runs to the wire, the 18-month backstop of January 18, 2027 governs. Paradigm's GENIUS implementation guide maps the trigger logic against the agency timelines.
​

Implementation is already underway. The OCC published a proposed rule in early 2026, detailed in Sullivan & Cromwell's memo on the OCC proposal, and the FDIC and Treasury followed with their own proposals through April 2026. For teams choosing an issuer partner this year, the practical read is that the framework is taking shape in real time and the exact go-live date will be confirmed by when final rules publish.
​

For domestic issuers, the GENIUS Act sets the bar each token must meet to be offered to US persons: one-to-one reserves, monthly attested disclosure, an approved issuer license, and no yield to holders. For offshore tokens, access to US distribution depends on a Treasury comparability determination. The Act does not declare any specific coin safe or compliant; it defines the requirements those coins are measured against.
​

The contrast lands hardest along the domestic-versus-offshore line. Circle's USDC and PayPal's PYUSD are issued by US entities already aligned to monthly-attestation and reserve norms, so their path runs through the domestic issuer tiers. Global Dollar (USDG), issued under a Singapore-anchored consortium, faces the cross-border access questions the equivalency process is meant to resolve.
​

USDT is the clearest cross-border case. Tether's flagship token, the largest stablecoin at roughly $189B as of Q1 2026 per CoinGecko, is issued offshore, and as of this writing Treasury has not made a USDT comparability determination. Tether has separately moved to launch a US-domiciled, GENIUS-aligned token rather than reshape USDT itself, reported by Yahoo Finance. The takeaway for routing and treasury teams is that an issuer's domicile and license, not just its market cap, now determine where a token can move through regulated US venues.
​

This is also why the GENIUS Act strengthens the case for issuer-neutral infrastructure. Eco routes stablecoin transfers across 15+ chains and works across multiple issuers and rails, so a treasury team can shift settlement toward whichever compliant token fits a corridor without re-plumbing its stack each time the regulatory map updates.
​

The GENIUS Act and the EU's MiCA both require one-to-one reserves and both ban paying interest to stablecoin holders, but they differ on who can issue and how reserves are held. MiCA limits e-money token issuance to banks and licensed e-money institutions and forces a share of reserves into bank deposits. The GENIUS Act allows a broader set of issuers and keeps reserves in Treasury-style assets instead.
​

The two regimes converge on the headline rules and diverge on structure. MiCA's e-money token (EMT) framework, in force across the EU since 2024 and supervised in part by the European Banking Authority, restricts issuance to credit institutions and e-money institutions and mandates that at least 30% of reserves sit in bank deposits, rising to 60% for "significant" tokens. The GENIUS Act takes the opposite stance on reserve composition, steering issuers toward Treasury bills and away from bank-deposit concentration, as the World Economic Forum comparison of the two regimes describes.
​

For a team operating in both markets, the table below summarizes where the frameworks align and where compliance work splits.
​

The operating implication is that a token compliant in one market is not automatically compliant in the other. Reserve composition and issuer-eligibility rules differ enough that most issuers maintain separate entities or token variants per region. A deeper side-by-side, including the UK's FCA approach, lives in the related reading below.
