## Summary

The GENIUS Act — Guiding and Establishing National Innovation for US Stablecoins — passed in early 2026, giving the US stablecoin market its first comprehensive legal framework. Fidelity and major banks have described stablecoins as one of the defining financial themes of the year.

## What the GENIUS Act does

The Guiding and Establishing National Innovation for US Stablecoins Act — the GENIUS Act — became law in early 2026 after passing both chambers of Congress with bipartisan support. It is the first comprehensive federal legislation specifically governing stablecoin issuance in the United States.

The Act establishes a dual regulatory path. Large stablecoin issuers (above $10 billion in circulation) must be chartered by a federal banking regulator — either the OCC, Federal Reserve, or FDIC — and maintain 1:1 reserves in US dollars or short-dated Treasuries, subject to monthly third-party attestation. Smaller issuers can operate under state-level money transmitter licences, subject to a federal minimum standard floor.

Crucially, the Act explicitly prohibits algorithmic stablecoins from using the label 'stablecoin' unless they can demonstrate full collateralisation. This provision directly targets models like Terra/UST and forecloses that design pattern from US-regulated markets.

## Winners and losers

Circle (USDC) is the clearest winner. USDC already holds reserves almost entirely in US Treasuries, operates with full monthly attestations, and has the compliance infrastructure to seek federal chartering. The GENIUS Act essentially legitimises Circle's existing model and gives it a significant competitive moat against issuers without equivalent compliance programmes.

Tether (USDT) faces a more complex path. USDT has historically been more opaque about reserve composition. While Tether has improved its attestation programme, its reserves include commercial paper and other non-Treasury assets that would require restructuring to meet GENIUS Act standards for US-regulated distribution.

PayPal's PYUSD, issued through Paxos, is well positioned. Fidelity's tokenised money market fund and several bank-issued stablecoins in development are now on a clear regulatory path. Banks including JPMorgan, Bank of America, and Wells Fargo are reportedly accelerating their own stablecoin development programmes.

## Implications for DeFi

The GENIUS Act has a DeFi carve-out: the legislation explicitly does not regulate DeFi protocols that remain non-custodial and do not hold user funds. This largely follows the SEC's parallel DeFi ruling in 2026 that exempted neutral, non-custodial interfaces from broker-dealer registration.

The combined effect is significant regulatory clarity: centralised stablecoin issuers now have a clear path to legal operation, while DeFi protocols that work with these stablecoins on a non-custodial basis are explicitly out of scope. This two-tier approach mirrors how banking law treats the difference between banks and exchanges.

Fidelity's 2026 outlook described stablecoins as 'one of the most significant financial innovations of this decade' and projected the stablecoin market could grow from $230 billion today to over $1 trillion within three years under the new regulatory clarity.
