The public comment window on Washington’s stablecoin identity rule closes today. What five federal agencies have proposed is narrower than the headline suggests: a know-your-customer perimeter drawn tightly around the moment dollars become stablecoins, and around almost nothing after that.
On June 18, the Treasury’s Financial Crimes Enforcement Network issued a joint proposed rule with the Office of the Comptroller of the Currency, the Federal Reserve Board, the FDIC and the National Credit Union Administration. It implements the GENIUS Act’s instruction that permitted payment stablecoin issuers be treated as financial institutions under the Bank Secrecy Act and be made to run an effective customer identification program. It hit the Federal Register on June 22. Comments were due by August 21.
The catch is in the scope. The proposal applies the identification requirement to the primary market only — customers who deal directly with an issuer. That means issuing, converting, redeeming, repurchasing, burning and reissuing stablecoins, plus the custodial services attached to those steps. Everything downstream sits outside: exchanges, self-hosted wallets, peer-to-peer transfers, payments to vendors, smart contracts. By the agencies’ own estimate, roughly 99% of stablecoin activity happens out there in the secondary market, where the issuer may never learn who is holding the token.
The perimeter is at the mint, not the payment
This is a deliberate design choice, not an oversight, and the agencies said so in the proposal. The logic is that an issuer can only identify the party it actually transacts with, and stablecoins are built to circulate without the issuer in the loop. Extending KYC to every hop would mean regulating the wallets and intermediaries rather than the issuers — a much larger undertaking that the GENIUS Act did not authorise in this rulemaking.
Not everyone at the table agreed the tailoring was right. Fed governor Michael Barr said in a statement that the framework “does not do enough so far to address the risks of illicit finance conducted through secondary market transactions in payments stablecoins.”
Our take: Read this as a scoping decision with a long tail, not a loophole someone forgot to close. Regulators put the gate where they have jurisdiction and leverage — the issuer’s front door — and left the rest for later rulemakings or for Congress. For anyone building on stablecoin rails, the compliance cost lands on mint-and-redeem infrastructure first. The secondary-market question does not disappear; it just gets answered somewhere else, later, and probably harder.
Why the banks are unhappy
The lobbying has not been about illicit finance. The Bank Policy Institute and The Clearing House filed comments on the related AML and sanctions requirements, and banking groups including the Consumer Bankers Association have pressed on what they call the competitive playing field between banks and permitted issuers. The specific worry is a structure that lets stablecoin arrangements pay something like interest, pulling funding that would otherwise sit in deposits. That is a balance-sheet argument wearing a compliance jacket, and it is the one likeliest to shape the final rule.
It is the second GENIUS Act rulemaking to matter this summer, after Treasury’s work on the definitions that decide who can issue at all. Both land while the commercial side keeps moving — Visa has already productised stablecoin settlement for merchants — which is the usual order of operations: the rails get built, then the rulebook catches up.
What to watch
- Whether the final rule keeps the primary-market limit or stretches toward intermediaries after the comment file is read.
- The companion FinCEN and OFAC rulemaking on AML and sanctions obligations, which carries the heavier ongoing compliance burden.
- Whether Barr’s secondary-market objection shows up as a separate proposal or gets left to Congress.
- The deposit-competition fight — if banks win language limiting yield-like features, the economics of issuing change materially.
