The GENIUS Act is the most important piece of US crypto legislation of the last decade. Signed in July 2025 after multi-year bipartisan work, it creates the first federal regulatory framework for payment stablecoins in the United States. It determines who can issue a stablecoin, what backs them, how they’re examined, and what retail holders can expect from the asset class going forward. Most of the day-to-day regulatory discussion in 2026 traces back to it.
This guide covers what the law actually does, how it affects the major stablecoins you might hold, and what the practical implications are for retail users in the US, UK, and EU.
What the Act actually does
The Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act is federal law. It established three categories of legal stablecoin issuer in the United States:
Federally-qualified stablecoin issuers. National banks, federal credit unions, and a new designation for non-bank issuers (Federal Qualified Stablecoin Issuers, FQSIs) meeting capital, compliance, and reserve requirements. Regulated by the OCC primarily, with FinCEN and the Fed playing roles.
State-qualified issuers. Issuers under existing state money transmitter regimes can issue stablecoins up to a size threshold (initially $10B total outstanding). Above that threshold, federal qualification is required.
Foreign issuers. Stablecoins issued by non-US entities (Tether, EU-based issuers) can be distributed in the US only through US-compliant distributors meeting specific conditions, including reserve transparency equivalent to domestic standards.
It also prohibits certain activities: algorithmic stablecoins without adequate reserve backing (Terra-style) cannot be distributed in the US. Stablecoin issuers are prohibited from paying yield or interest on stablecoin balances directly. Issuers must meet specified reserve requirements — essentially, cash and short-duration US Treasury bills, with limited flexibility for other enumerated safe assets.
Implementing rules were issued through 2025 and 2026 by the OCC, FDIC, FinCEN, and other agencies. Compliance by major issuers is phased; the full effective date for most provisions is mid-2026.
What this means for USDC
Circle (issuer of USDC) is a GENIUS Act-compliant federally qualified issuer. USDC reserve composition was already close to GENIUS requirements before the law passed, which positioned Circle well for rapid compliance. Under GENIUS, Circle:
- Holds reserves in cash and short-duration US Treasuries at US-insured banks.
- Submits to monthly reserve attestations and quarterly compliance filings.
- Is subject to OCC examination.
- Cannot pay yield on USDC balances directly.
For USDC holders, the practical effect is modest: USDC reserve composition is cleaner and more transparent, US exchange listings are reinforced, and the regulatory uncertainty that shadowed USDC in 2022-2024 has largely been replaced with clear federal rules.
What this means for USDT
Tether (issuer of USDT) is not a US entity. The GENIUS Act does not directly regulate Tether, but it does regulate US entities that distribute Tether. Two practical consequences:
US exchange access has contracted. Some US exchanges delisted USDT or restricted USDT services to avoid compliance friction. Coinbase never supported USDT for direct purchase in the first place. Other exchanges adjusted their USDT offerings to comply with GENIUS Act distribution rules.
Tether has not become a US-licensed issuer. Tether has said it will comply with applicable regulations but has not pursued federal qualification. USDT remains the dominant stablecoin globally by market cap; its US availability has diminished since 2025.
For US retail users in 2026, USDC is the practical default stablecoin for regulated venues. USDT is still accessible but through fewer channels.
What this means for other stablecoins
Bank-issued stablecoins became more viable post-GENIUS. JPMorgan, Standard Chartered, HSBC, and others have launched or are launching stablecoins under GENIUS framework. These tend to serve institutional use cases rather than retail but expand the competitive landscape.
DAI (MakerDAO) operates as a decentralized, crypto-collateralized stablecoin without a US issuer. GENIUS doesn’t directly regulate DAI issuance but constrains how US entities distribute it. DAI remains accessible through DeFi protocols and some exchanges.
PYUSD (PayPal USD) is GENIUS-compliant and integrated with PayPal’s payment rails. It’s a US-regulated stablecoin growing through existing PayPal merchant networks.
Algorithmic stablecoins (Terra’s UST pattern) are effectively blocked from US distribution. Previously proposed designs for partially-collateralized stablecoins face legal ambiguity and have not been brought to market in the US post-GENIUS.
The yield question
One of the most contested aspects of the GENIUS Act is its prohibition on stablecoin issuers paying interest to holders. The policy logic: if stablecoin issuers could pay yield, stablecoins would become money market funds in effect, and subject to a different regulatory regime (the Investment Company Act of 1940 and related rules). The GENIUS framework keeps stablecoins as payment instruments rather than yield products.
This has had specific consequences:
- Circle cannot pay interest on USDC held with Circle directly.
- Earning yield on stablecoins requires separate mechanisms. Lending on DeFi (Aave, Morpho) or exchange-offered lending programs are legal but not “stablecoin yield”; they’re interest from lending.
- Legislation to permit yield-paying stablecoins has been proposed but not passed. The coalition supporting yield-paying stablecoins includes fintechs and some crypto industry players; opposition includes banks (who see yield-paying stablecoins as a threat to bank deposits) and traditional money market regulators.
Expect the yield debate to continue through 2026 and 2027.
For EU and UK readers
The GENIUS Act is US law. It affects US distribution of stablecoins. For EU readers, MiCA (Markets in Crypto-Assets Regulation) is the equivalent framework — it took full effect through 2024-2025 and has specific rules for stablecoins that differ from GENIUS in details. USDC is MiCA-compliant; USDT has had friction with MiCA and is limited on some EU venues.
For UK readers, the FCA has been developing its own stablecoin framework broadly influenced by GENIUS and MiCA. The UK has not replicated GENIUS directly; expect continued UK-specific rules through 2026.
What stablecoin holders should know
If you’re in the US: USDC is the cleanest compliant stablecoin. USDT works through fewer channels than before but remains accessible. Bank-issued stablecoins are emerging and may serve some use cases.
If you’re in the EU: USDC has full MiCA compliance. USDT is restricted on some venues. Local EUR-denominated stablecoins (EUR CoinVertible, EURC from Circle) are smaller but exist for euro-specific needs.
If you’re in the UK: Both USDC and USDT are available through FCA-registered exchanges. UK-specific stablecoin regime is still evolving; expect more change through 2026.
For everyone: Stablecoin yield requires DeFi or exchange lending products, not the stablecoin issuer itself. See DeFi yield farming guide for the mechanics.
The broader regulatory picture
The GENIUS Act is part of a broader shift in US crypto regulation toward clearer rules. The SEC under Paul Atkins (replacing Gary Gensler in January 2025) has moved from enforcement-first to guidance-first. The CFTC’s role has expanded under various legislative and regulatory adjustments. State-level crypto regulation (particularly on prediction markets and consumer protection) has been active.
For retail crypto users, the net effect is the regulatory environment is less hostile than in 2020-2024 but more structured. Compliance matters more; options for fully-unregulated activity have narrowed.
