The GENIUS Act: A Treasurer's Diligence Guide

The Guiding and Establishing National Innovation for U.S. Stablecoins Act became Public Law 119-27 on July 18, 2025. The market read it as a green light for digital dollars. Treasurers should read it as a rulebook for the entities that issue them. The Act defines who may issue a payment stablecoin, dictates what must back one, and guarantees the holder a right to redeem at par. Each provision is a credit question, not a technology question. Mid-July 2026 is a deadline for regulators, not for you. The diligence work should start now.

A Credit Standard, Not a Crypto Rule

Most commentary on the GENIUS Act treats it as the moment digital dollars went mainstream. That framing is correct and unhelpful. It tells a treasurer nothing about what to do on Monday. A more useful reading starts from what the statute actually regulates. It regulates reserves. It regulates redemption. It regulates supervision. Those are the three pillars of any credit instrument a treasury already holds, from a money market fund to a bank deposit.

Strip away the vocabulary of tokens and chains. What remains is a familiar question. If this counterparty fails, do I get my dollar back, in full, on demand. The GENIUS Act is Congress answering that question with structure rather than faith. A payment stablecoin is not a currency to be trusted. It is a claim to be underwritten. The Act passed with bipartisan support, the Senate 68 to 30 and the House 308 to 122, then was signed into law. The diligence questions below are the ones every treasury team should be asking, regardless of who runs the process.

Test One: Who Is a Permitted Issuer

The first screen is legal status. A token can carry a familiar brand, a large float, and a clean track record, and still sit outside the federal framework. The Act recognizes three classes of permitted payment stablecoin issuer. The first is a subsidiary of an insured depository institution, supervised by the bank's primary federal regulator, which may be the OCC, the FDIC, or the Federal Reserve. The second is a federally qualified nonbank issuer, approved and supervised through the OCC. The third is a state-qualified issuer operating under a state regime the Treasury has deemed acceptable.

The classes are not interchangeable. State-qualified issuers face a hard ceiling. Once outstanding issuance exceeds $10 billion, the issuer must transition to a federal regime. That threshold is a structural signal, not a footnote. The diligence point is narrow. Issuer status is the first screen, not market capitalization. A large unregulated token is still an unregulated counterparty. Size flatters. Status protects.

Test Two: Reserve Quality

Backing is where the credit work concentrates. The Act sets a floor of at least one dollar of permitted reserves for every dollar issued. The composition of that dollar is prescribed, not left to the issuer. Permitted reserves are limited to a short list. They include U.S. coins and currency, demand deposits at insured depository institutions, balances at Federal Reserve Banks, Treasury bills with 93 days or less of remaining maturity, repurchase agreements collateralized by those bills, and qualifying government money market funds.

Two features deserve attention. The first is the 93-day maturity ceiling on Treasury bills. That cap exists to limit duration and liquidity risk inside the reserve pool. The second is what the list excludes. Algorithmic stablecoins, which attempt to hold a peg through code and incentives rather than full asset backing, do not qualify. Disclosure is part of the design. Reserve composition must be published periodically, certified by executives, and examined by a registered public accounting firm. Issuers with more than $50 billion outstanding must file audited annual financial statements. The diligence point is operational. Read the attestation, not the logo.

Test Three: Redemption Certainty

A reserve pool is only as useful as the right to draw on it. The Act gives holders a clear, enforceable right to redeem stablecoins for U.S. dollars at par, on demand. That right is not a marketing promise. It is paired with disclosure obligations. The issuer must publish a redemption policy. Any redemption fees must be disclosed in plain language. Fee changes require at least 7 days of advance notice before a change can take effect.

For a treasury function, this is the test that matters most under stress. Yield is a peacetime question. Redemption is a wartime one. The relevant inquiry is not what a token earns. It is whether the treasury can convert it to dollars at par, in size, on the day it needs to. Read the published redemption policy the way a credit officer reads a liquidity covenant. Note the par guarantee. Note the fee schedule. Note the notice period. Note any operational limits on redemption size or timing.

Test Four: The Timeline Trap

The date attached to this analysis is widely misunderstood. Mid-July 2026, near the July 18 anniversary of enactment, marks a one-year statutory deadline for the primary federal regulators to issue implementing rules. It is a deadline for agencies. It is not a compliance date for issuers, treasurers, or counterparties. The compliance date is set separately. The Act takes effect on the earlier of two events. The first is 18 months after enactment, which falls on January 18, 2027. The second is 120 days after the primary federal payment stablecoin regulators issue final implementing regulations. Whichever comes first governs.

As of mid-2026, that second trigger has not occurred, because no final rules exist. The OCC issued a notice of proposed rulemaking, OCC Bulletin 2026-3, dated February 25, 2026, published in the Federal Register on March 2, 2026. The FDIC issued its own notice of proposed rulemaking, published April 10, 2026, with a comment period that closed June 9, 2026. FinCEN published a related proposal on anti-money-laundering and sanctions-compliance program requirements on the same April date. Each of these is a proposal. None is final.

The trap is to read the framework as already binding and to wait for a single switch to flip. The better posture is the opposite. The rules are not yet final, so the standards may still shift at the margin. The diligence questions, however, are already knowable from the statute. A treasury team that builds its underwriting process during the proposal window will not be improvising when final rules arrive. Build the diligence now. Do not wait for the date.

A Checklist for the Next 18 Months

The work between now and the compliance date is preparatory, not reactive. The following questions apply to any payment stablecoin a treasury might hold, accept, or settle in. They are inquiries, not a scoring method.

• On issuer status. Which of the three permitted classes does the issuer occupy. Who is the named supervisor. If state-qualified, how close is outstanding issuance to the $10 billion federal-transition threshold.
• On reserves. Does the published reserve report show at least 1:1 backing in permitted assets only. Are Treasury holdings within the 93-day ceiling. Which firm performs the examination, and how recent is the latest attestation.
• On redemption. Is the par redemption right published and unconditional. What does the fee schedule say. What is the notice period for fee changes. Are there operational limits that would bind in a stressed week.
• On internal readiness. Does treasury policy define eligible counterparties and instruments before any exposure is taken. Is there a defined process to re-underwrite when final rules publish. Who owns the decision, and who reviews it.

These questions do not require waiting for July 18. They require reading documents the statute already mandates issuers to produce. The GENIUS Act will be remembered as a payments milestone. Treasurers should treat it as a credit framework. Its operative provisions govern who issues, what backs, and how holders redeem. Those are underwriting questions a treasury function already knows how to answer. The discipline reduces to one line. Underwrite the issuer, not the coin.
