NCUA's Proposed Stablecoin Standards: Credit Unions Could Issue Only Through a Subsidiary; Stablecoins Get No Share Insurance

On May 18, 2026 a supplemental proposed rule from the National Credit Union Administration (NCUA) implementing the GENIUS Act was published in the Federal Register, cited as 91 FR 28956, its ACTION field reading Supplemental proposed rule. Three dates belong apart: the document is signed on May 14, filed with the Office of the Federal Register and announced in an NCUA press release on May 15, and published on May 18.

This article was checked on September 17, 2026, reading the original Federal Register PDF on the U.S. Government Publishing Office's govinfo, the NCUA press release of May 15, the enacted text of the GENIUS Act, and the agency's earlier proposal of February 12 of the same year. We have tested nothing ourselves, and we give no investment or legal advice. This is a proposal and not a rule in force; where the agency has not said something, this article says so rather than filling the gap by inference.

What this document is: a supplemental proposal, with an earlier one behind it

The GENIUS Act is the 2025 U.S. law on payment stablecoins, Public Law 119-27, and its enacted text ends "Approved July 18, 2025." It divides the licensing and supervision of payment stablecoins among several Federal agencies and the States, and this article covers one strand of that. The agency note at the end of the press release describes the NCUA as the federal agency created by the U.S. Congress to regulate, charter and supervise federal credit unions.

The NCUA published first, on February 12, 2026, the proposal dealing with who may apply and how an application is reviewed (91 FR 6531, RIN 3133-AF69, comments due by April 13 of the same year); what the May document adds is the standards, and the two carry different RIN and docket numbers. The May document draws its own line: unless explicitly stated in this supplemental proposal, the NCUA is not reproposing or otherwise modifying the provisions proposed in the licensing proposal, so most of the licensing procedure that appears in the May regulatory text was proposed in February and is reproduced here.

On the comment deadline, both the DATES field in the Federal Register and the NCUA press release say July 17, 2026; the full text poses 199 numbered questions (Question 1 through Question 199), which makes it a request for comment rather than a settled rule. Section 13 of the GENIUS Act requires each primary Federal payment stablecoin regulator, the Secretary of the Treasury and each State payment stablecoin regulator to promulgate regulations not later than one year after the date of enactment, and the NCUA, in the summary of its February proposal, printed that deadline as July 18, 2026.

Whom it reaches: a credit union cannot issue itself, only through a subsidiary

Credit unions are unfamiliar ground for readers in Taiwan: the NCUA speaks of the cooperative model in which credit unions operate, the money a member puts in is a share account in U.S. law, and it is covered by the NCUA's Federal share insurance rather than by the deposit insurance that applies to banks; a credit union insured by the NCUA is a federally insured credit union, FICU for short.

Under the GENIUS Act, insured depository institutions, which the document calls IDIs and which take in both depository institutions insured by the Federal Deposit Insurance Corporation (FDIC) and FICUs, cannot be issuers of payment stablecoins and must use subsidiaries as issuers; the proposal states that FICUs are not permitted to issue payment stablecoins directly. The statutory definition of an insured credit union subsidiary has three separate prongs: an organization providing services related to the routine operations of a credit union, a credit union service organization (CUSO) in which the credit union holds an ownership interest or to which it has lent, and a subsidiary of a State-chartered insured credit union established under State law; each prong is a separate and distinct avenue to qualify. Such a subsidiary must be regulated by the primary Federal payment stablecoin regulators and cannot opt for the state-level framework; the document says those regulators include the NCUA, the FDIC, the Office of the Comptroller of the Currency (OCC) and the Board of Governors of the Federal Reserve System.

The application and its review come from the February proposal and are reproduced in the May regulatory text: the subsidiary must file jointly with any insured credit union parent company; the GENIUS Act requires the NCUA to render a decision not later than 120 days after receiving a substantially complete application, and the application is deemed approved if no decision is rendered within that period, while an application already considered substantially complete stays so unless there is a material change in circumstances that requires the NCUA to treat it as a new application; not later than 30 days after receiving an application the NCUA is to notify the applicant whether it determined the application substantially complete; and the issuance of a payment stablecoin on an open, public, or decentralized network is not a valid ground for denial. The February proposal also limits a credit union to investing only in an issuer already licensed by the NCUA.

What the May document proposes: permitted activities, reserves and redemption

Proposed § 706.201 begins by fencing off the business: an NCUA-licensed permitted payment stablecoin issuer may only do eight things, among them issuing, redeeming, managing reserve assets, providing custody or safekeeping for the stablecoins and for the reserves and private keys required, and charging a fee for purchase or redemption. Two of the prohibitions in the same section matter most to an ordinary reader: the issuer may not, directly or through implication, represent that payment stablecoins are backed by the full faith and credit of the United States, guaranteed by the United States Government, or subject to Federal deposit insurance or Federal share insurance; and it may not pay the holder any form of interest or yield, whether in cash, tokens, or other consideration, solely in connection with the holding, use, or retention of the coin itself.

The proposal would require reserve assets to have, at all times, a total fair value that equals or exceeds the outstanding issuance value, to be identifiable and segregated from the issuer's other assets, and monthly composition reports to be published and examined by a registered public accounting firm. A shortfall would have to be reported to the NCUA on the day it occurs, and new issuance would be prohibited immediately (other than issuance solely to move stablecoins across ledgers where the net outstanding issuance value does not increase); after 15 consecutive business days below the minimum, which may be extended in the NCUA's sole discretion, the issuer would have to begin liquidating reserve assets and redeeming, and could not charge a redemption fee at any time during the liquidation. The redemption policy would have to state that timely redemption may not exceed two business days following the date of the requested redemption and that any discretionary limitation can only be imposed by the NCUA; where redemption requests exceed 10 percent of the outstanding issuance value in a single 24-hour period, the period would be automatically extended to seven calendar days, and the NCUA could extend it in its discretion as well, for safety and soundness, financial stability, or otherwise in the public interest.

On capital and supervision, the NCUA says that where possible the proposed part would maintain consistency with the standards and terminology proposed by the other primary Federal payment stablecoin regulators: a de novo issuer, one licensed to issue for less than three years, would hold minimum capital equal to the greater of the amount specified in its licensing conditions or $5 million, and would hold that minimum for 36 months, which its licensing conditions or a later NCUA determination may shorten or lengthen, plus an operational backstop of assets equal to 12 months of total expenses, presented separately from the reserve assets.

Where the coverage stops: no share insurance for the coin, share insurance for tokenized shares

The GENIUS Act explicitly dictates that payment stablecoins are not backed by the full faith and credit of the United States, are not guaranteed by the U.S. Government and are not covered by deposit or share insurance from the FDIC or NCUA, and it is unlawful to represent otherwise. On the reserve side, the proposal's treatment is this: funds held in share accounts at a credit union as reserves for a payment stablecoin would be insured to the issuer under the coverage rules for corporate accounts, not passed through to holders, and would be aggregated with the issuer's other corporate accounts at the same credit union, up to the standard maximum share insurance amount (SMSIA), currently $250,000. The NCUA's reason is that, the statute reading as it does, providing share insurance to payment stablecoin holders on a pass-through basis appears to be inconsistent with those provisions.

The same proposal deals separately with tokenized shares. The NCUA states that payment stablecoins and tokenized shares are economically and legally distinct, and that the GENIUS Act's definition of a payment stablecoin expressly excludes a deposit, including a deposit recorded using distributed ledger technology. The proposal would therefore amend the share insurance rules to make clear that the technology or type of recordkeeping an insured credit union uses to record account liabilities does not affect whether those liabilities constitute accounts; a member using tokenized shares is afforded the same Federal share insurance as a member using non-tokenized shares.

What it means for readers in Taiwan, and how to check it yourself

The boundary first: this is a U.S. proposed rule, it reaches U.S. federally insured credit unions and their subsidiaries, it does not bind users, platforms or regulators in Taiwan, and the full text does not mention Taiwan. What follows is an example we constructed editorially, not something we tested: someone pays an overseas freelancer with a U.S. dollar stablecoin, sees "issued by a subsidiary of an insured credit union", and reads it as deposit insurance. On the terms of the proposal that reading is wrong: the issuer is forbidden to make such a representation, and the stablecoin itself has no share insurance.

To check where things stand yourself, the steadiest route is back to the Federal Register and govinfo: this document is number 2026-09915 under RIN 3133-AG10, and the February one is 91 FR 6531 under RIN 3133-AF69. As for when the GENIUS Act takes effect, section 20 gives a formula rather than a date: the Act and its amendments take effect on the earlier of 18 months after the date of enactment, or 120 days after the primary Federal payment stablecoin regulators issue any final regulations implementing the Act. The NCUA's proposal prints that formula as well and does not convert it into a date, and neither does this article.
