The Stablecoin Rules Know the Mint, Not the Market

The most revealing thing about the new US rules on stablecoin identification is the sentence about who does not count as a customer.

If you buy a dollar-pegged token on an exchange, hold it in your own wallet, send it to a friend, or spend it at a merchant, the emerging federal framework treats you as someone the system does not need to identify. The regime reaches the moment a token is minted from a dollar and the moment it is burned back into one. The long stretch in between, where the digital dollar actually circulates, sits outside its line of sight.

That is the seam the American banking industry spent the summer trying to close.

Who counts as a customer?

The distinction doing the analytical work is between two markets that sound similar and behave very differently. The primary market is where a stablecoin is created and destroyed: an issuer takes in dollars, mints tokens backed by reserves, and redeems them back to dollars on request. The secondary market is everything else — every trade on an exchange, every wallet transfer, every payment routed through a digital asset service provider. It is the market where the peg is actually tested, and, as the Federal Reserve has noted in its own research, where most stablecoin demand, usage and price discovery takes place.

The new rules were written to reach only the first of those. In June, FinCEN, the OCC, the Federal Reserve, the FDIC and the National Credit Union Administration jointly proposed a customer identification program for permitted payment stablecoin issuers — the nonbank issuers the GENIUS Act treats as financial institutions under the Bank Secrecy Act. The proposal would require an issuer to know the true identity of anyone opening an account with it, down to name, address and tax identification number, and to hold the records for five years.

The definition of "account" is where the interesting part sits. The proposal covers issuing and redeeming, managing reserves, and holding private keys for customers — the direct, on-the-books relationships an issuer has. It expressly excludes interaction with an issuer's smart contract, and it excludes anyone who acquired the tokens somewhere other than directly from the issuer. The plain reading: a holder of USDC bought on an exchange is nobody's customer under this rule.

A second carve-out runs at the identification level itself. In an April rulemaking, FinCEN said it was not contemplating applying customer due diligence or beneficial-ownership collection to secondary-market activity.

The gap matters because of where the money actually lives. Tether's USDT carries a market cap of roughly $183 billion, with Circle's USDC near $73 billion, per Ainvest market data — more than a quarter of a trillion dollars of tokenized dollars between them, and USDT alone is about seven percent of the entire crypto market's value. Almost none of that value sits in the primary market; it is on exchanges, in wallets, in settlement flows. In other words, the US regime's first instinct — put the entire identity burden on the people who mint and burn the tokens — regulates the smallest and most tightly controlled part of the system, while declining to see the part where the tokens actually move.

The banks' summer campaign

The Bank Policy Institute, the bank industry's research and advocacy arm, and The Clearing House have spent the summer arguing that this design has the burden in the wrong place. In their June comment on the anti-money-laundering rule, they pointed to FinCEN's own acknowledgment that the majority of illicit stablecoin activity occurs on the secondary market, and argued that the framework imposes no comparable obligations on the custodians, exchanges and digital asset service providers where that activity happens. Many of those platforms are state-licensed money transmitters, they noted — entities that do not carry the formal customer identification requirements banks have operated under for decades. Their ask: extend comparable standards to the secondary market through future rulemakings, backed by the statutory authority they want Congress to provide.

A second comment, filed as the August window closed, adds the nuance that makes the position legible as politics rather than purity. BPI and The Clearing House want de minimis thresholds — an exemption for low-value transactions — and clearer boundaries on when full identity verification is triggered. They are not asking to photograph every two-dollar transfer. They are asking that the infrastructure moving large pools of digital dollars be held to bank-grade identity standards, with banks as the benchmark.

Looked at that way, the push is about more than safety. This is a constituency play. Every time a dollar-denominated token hops through the secondary market without identity checks, it moves outside the reach of the bank-operated rails that gave the clearing system its grip on payments. Pulling the secondary market under bank-style identification does more than complicate illicit finance; it turns the most active part of the stablecoin economy into something that behaves like bank money, with every participant known to an institution running a compliance program. That is a reasonable public-policy outcome worth debating on its merits. It is also, conveniently, the outcome the banks' competitors would have to pay for.

It is not an isolated move either. Last September the same institute, with the Association of Global Custodians and the Financial Services Forum, urged the SEC to apply "proven safeguards" to crypto custody rules — a similar argument that crypto infrastructure should just adopt the banking playbook. The stablecoin identification fight is the same play on a bigger board: if the rails that carry dollar tokens are made to look and cost like bank rails, the banks keep a seat in the middle of the stack.

What the two sides are really negotiating is where legitimacy in digital dollars lives. The US regime is building its identity layer around the issuer: one regulated institution at the center of minting and redemption. The EU's model wires identity into the transfer itself — its version of the travel rule applies to every crypto transaction, with no size floor, so that originator and beneficiary information moves with the payment rather than living with the issuer. Two different architectural answers to the same question. The US answer says legitimacy lives at the institution. The EU answer says it lives in the payment.

The immediate sequence is fairly clear. FinCEN will finalize the issuer identification rule, leaving the secondary market as the explicit open item the banks have told Congress and the agencies to close. From there the fight shifts to whether exchanges — some of which would privately welcome uniform federal identification standards because they would level compliance costs against offshore competitors — get folded into a federal identification regime of their own, and whether self-custody transfers remain the one space the rules continue to refuse to see.

The sharper question is structural. If secondary-market identification arrives, the digital dollar completes a quiet migration: from a peer-to-peer rail whose users can move value without a bank, to a settlement layer where a regulated institution is presumed present at every hop. The public argument is about illicit finance. The underlying trade is about who gets to sit between the token and the user — and which layer of the digital-dollar stack the banks get to own.
