The GENIUS Act — the Generating Economic Norms in USD Stablecoins Act — is now federal law. After two false starts in 2024 and a near-miss in early 2026, the bill that defines what a 'payment stablecoin' is, how it must be reserved, and what disclosures issuers owe their holders has cleared Treasury implementing guidance.

What changes for issuers

All payment stablecoins must hold 1:1 reserves in US treasuries, central-bank deposits, or short-term repo collateral. Reserves must be attested monthly by a registered public accounting firm and published on-chain via a recognised proof-of-reserve oracle. Holders get a statutory right to par redemption within one business day.

The second-order effect lands on tokenised treasuries. BUIDL, BENJI, USYC, OUSG — every fund holding short-dated US debt as collateral is now adjacent to the only federally-recognised payment rail. Stablecoin issuers will buy these funds as reserve assets. The asset layer and the payment layer just merged.

The GENIUS Act doesn't just legalise stablecoins. It makes tokenised treasuries the default reserve asset for the entire payment industry.

Who wins, who waits

Circle and Paxos are first-mover compliant. Tether is conspicuously silent on US compliance and faces a 12-month decision window. Smaller US-dollar pegs face a real existential question: comply, partner, or exit.

→ The takeaway

The asset and payment layers of the on-chain economy now have legal definition. CLARITY for securities is the next domino. The tokenised-equities desk should be paying attention to both.
