GENIUS Act Final Rule Explained
The OCC finalized its GENIUS Act rule on Oct 21, 2026. Here's what it requires of stablecoin issuers, when it takes effect, and what it means for apps.
On October 21, 2026, the Office of the Comptroller of the Currency (OCC) published its final rule implementing the GENIUS Act, the U.S. federal law for payment stablecoins. The rule sets out how OCC-supervised issuers must back stablecoins (at least 1 to 1 with reserve assets), how fast they must honor redemptions (no more than two business days), what they must disclose (a monthly reserve composition report), and how the ban on paying holders interest or yield works in practice. The rule and the GENIUS Act both take effect on January 18, 2027.
For anyone building financial applications that hold, move, or put stablecoins to work, this is the point where U.S. stablecoin regulation stops being a statute and becomes an operating manual.
What is the GENIUS Act?
The Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act) was signed into law on July 18, 2025. It creates a federal framework for "payment stablecoins", meaning digital assets designed to be redeemed for a fixed amount of money, and it sets licensing and regulatory requirements for the companies that issue them.
The law itself left many details, such as capital, liquidity, and operational risk standards, to be written by each issuer's primary federal regulator. The OCC's final rule is the first major piece of that work, covering issuers under its jurisdiction: subsidiaries of national banks and federal savings associations, federal qualified payment stablecoin issuers, certain state qualified issuers, and foreign payment stablecoin issuers.
What does the OCC's GENIUS Act final rule require?
The rule adds a new part to the OCC's regulations (12 CFR part 15). These are the requirements most relevant to the market.
Reserve backing of at least 1-to-1
Every permitted payment stablecoin issuer must back its total outstanding issuance on at least a 1 to 1 basis with reserve assets. The final rule clarifies valuation: U.S. coins and currency count at face value, while other reserve assets are valued at fair value. Compared with the March 2026 proposal, the OCC says it gave issuers more flexibility in how they manage reserves, while keeping core liquidity, diversification, and concentration requirements.
Redemption within two business days
Under Section 15.12 of the final rule, a timely redemption may not exceed two business days after the redemption request. The OCC declined requests to allow a longer window for cross-border redemptions, so the same standard applies to holders abroad. Issuers' use of tools like repurchase agreements cannot get in the way of meeting that deadline.
Monthly reserve composition reports
Issuers must publish a monthly report on the composition of their reserves. If reserves are segregated by brand, the report has to list each class or brand of stablecoin separately. Separately, the OCC is finalizing weekly and quarterly supervisory reporting forms, with the first weekly report date currently set for January 25, 2027, subject to approval by the Office of Management and Budget.
The yield prohibition
The GENIUS Act bars issuers from paying interest or yield to holders solely for holding, using, or retaining a payment stablecoin. This was one of the most debated parts of the rulemaking. The final rule notes that the prohibition can reach indirect payments, where an issuer routes yield to holders through someone else, and it distinguishes custodians that simply control stablecoins on a customer's behalf from parties that benefit economically from a payment.
Custody and the $10 billion threshold
The rule also covers certain custody activities by OCC-supervised entities, including safekeeping of payment stablecoins and reserve assets. The OCC also closely monitors large state-chartered issuers: it may review affiliates' issuance if a state issuer appears to use them to stay under the $10 billion threshold that triggers a move to the federal framework.
When does the GENIUS Act take effect?
The GENIUS Act and the OCC's final rule both take effect on January 18, 2027. Supervisory reporting starts shortly after, with the weekly form tied to a January 25, 2027 report date and the quarterly form to March 31, 2027.
Can stablecoins pay yield under the GENIUS Act?
Issuers cannot pay holders interest or yield just for holding a payment stablecoin, and the final rule makes clear that routing such payments through a third party can also fall within the ban. That restriction applies to the issuer. Yield in onchain finance usually comes from putting assets to work, for example by supplying stablecoins to a lending market or depositing them into a vault, which is a separate activity with its own risks and its own legal analysis. Teams building yield products should get specific legal advice on how their design interacts with the rule.
GENIUS Act vs. CLARITY Act: what's the difference?
The two bills are often mentioned together, but they cover different ground. The GENIUS Act is about payment stablecoins: who can issue them, how they are backed, and how they are supervised. It is law, and its implementing rules are now arriving. The CLARITY Act (Digital Asset Market Clarity Act) is a broader market structure bill that would divide oversight of digital assets between the SEC and the CFTC and set rules for exchanges, custody, and token fundraising. It passed the House in July 2025 but has not become law; according to reporting summarized on X, it failed a key Senate vote in September 2026 [TBD: confirm current Senate status before publishing].

What the final rule means for financial applications
Clear federal issuance rules make regulated stablecoins easier for banks, fintechs, and payment companies to adopt. Two features of the rule matter directly for product teams.
The first is predictability. A defined redemption window, 1 to 1 backing, and monthly reserve disclosures give applications a clearer basis for deciding which stablecoins to support and how to describe them to users.
The second is distribution. As more regulated issuers enter the market, applications will need to support more stablecoins across more networks, and to connect them to the onchain activity users want, such as swapping between stablecoins, supplying them as collateral, or depositing them into yield strategies.
That second point is an execution problem, and it is where infrastructure matters.
Where Enso fits: execution infrastructure for stablecoin flows
Enso is execution infrastructure for onchain finance. Applications use a single API to turn a user's intent into signer-ready transaction data, while the application keeps custody, policy, and user experience control. Enso is not a stablecoin issuer and does not provide custody or compliance services; it handles routing and transaction construction.
For stablecoin products, that covers a few concrete patterns:
- Route API finds a path from one position to another, for example from a stablecoin into a vault, and returns a single gas-optimized transaction that can combine swap, deposit, and redeem steps. On a single chain, that transaction executes atomically. (DeFi and Swap Routing)
- Bundle API lets a product define its own ordered sequence of actions, such as borrow, repay, or deposit, and receive one transaction to sign. (Bundle API)
- Crosschain routing lets applications combine bridging with actions on the destination chain, such as minting a stablecoin where its issuer operates and depositing it into a lending market elsewhere. Crosschain flows are coordinated across networks, so they don't carry the same atomic guarantee as a single-chain transaction. (Stablecoin use cases)
- Quoter simulates a transaction against the current on-chain state to predict output amounts and gas before the user signs, then validates that the transaction wasn't modified between simulation and signing. Simulation improves quote accuracy and reliability, but it can't remove every execution risk in fast-moving markets. (Quoter overview)
The business benefit is time to market. A team adding newly regulated stablecoins can make them usable across supported protocols and networks with one integration, instead of building and maintaining each protocol connection.
