The GENIUS Act: Reserve Architecture and Issuer Obligations

The Framework in One Paragraph

The GENIUS Act requires every payment stablecoin to carry full 1:1 backing in cash and short-duration, high-quality liquid assets, held by a licensed issuer under federal or equivalent state supervision. That is the entire architecture in outline. Everything else in the statute exists to make that single reserve promise enforceable. Six federal agencies are finishing the rules that convert this promise into operating law, against a deadline that falls this week.

What Counts as a Payment Stablecoin

The statute defines a payment stablecoin narrowly: fixed value relative to a set monetary amount, redeemable on demand at that value, fully backed by eligible reserve assets. It is explicitly not a national currency, a bank deposit, or a security. Algorithmic stablecoins without full reserve backing fall outside this definition and cannot be marketed as GENIUS-compliant.

The Issuer Licensing Structure

Only a Permitted Payment Stablecoin Issuer (PPSI) may issue payment stablecoins in the United States. Foreign issuers can qualify as FPSIs if their home regulator is judged comparable and they register with the OCC. Oversight splits on size: issuers above $10 billion in outstanding stablecoins fall under federal supervision; issuers at or below that threshold may operate under a certified state regime.

Reserve Requirements: The Core Mechanism

Every stablecoin must be backed 1:1 by US currency, insured demand deposits, Treasury bills maturing in 93 days or less, overnight repos, money market funds, or compliant tokenized reserve assets. Reserves cannot be rehypothecated, commingled with operating funds, or used to pay interest to holders.

The Rulemaking Sprint: Where Things Stand

The OCC, FDIC, Federal Reserve, NCUA, Treasury, FinCEN, and OFAC must finalize their rules by July 18, 2026. All major comment periods have closed. The statute contains no fallback if an agency misses the deadline. Even with rules finalized on time, full operational effect points toward a November 2026 window given the 120-day transition clock.

Institutional Reading

The reserve standard is now a floor, not a differentiator, since every compliant issuer will carry it. Redemption mechanics under stress are where real operational risk concentrates, and the compliance cost curve favors scale, pushing smaller issuers toward acquisition or exit.
