Treasury Puts Dates on the Stablecoin Deposit Rail
Treasury's proposed rule on section 3 of the GENIUS Act carries two different start dates for two different prohibitions. The sector's shorthand collapses them; the text does not.
The rail that most crypto casino cages run on now has a rulemaking attached to it. On 18 August 2026 the U.S. Department of the Treasury published a notice of proposed rulemaking implementing section 3 of the GENIUS Act in the Federal Register. It is a proposal: comments must be received on or before 19 October 2026, and nothing in it binds anyone today.
The caveat matters: the sector’s summary — “stablecoin deposits are being banned” — is wrong in both directions at once.
Two prohibitions, two clocks
Section 3(b) contains two distinct prohibitions, and they do not start together.
Section 3(b)(1) is the one everyone quotes. Beginning on 18 July 2028, three years after enactment, it is unlawful for a digital asset service provider to offer or sell a payment stablecoin to a person in the United States unless that stablecoin is issued by a permitted payment stablecoin issuer. That is a 2028 date.
Section 3(b)(2) draws far less attention, and is the nearer clock. It covers stablecoins issued by foreign payment stablecoin issuers, and the proposal says it “unlike section 3(b)(1) becomes applicable on the effective date of the Act.” The OCC’s bulletin on its own GENIUS Act rulemaking states that effective date as the earlier of 18 months after the 18 July 2025 enactment or 120 days after the primary federal payment stablecoin regulators issue final regulations. Eighteen months lands in January 2027; the earlier-of test means it can land sooner, and anyone pencilling in a fixed date has misread the sentence.
Where the offshore argument runs out
Section 3 is drafted to reach conduct abroad: the proposal states it is intended to have extraterritorial effect if the conduct involves the offer or sale of a payment stablecoin to a person located in the United States. Domicile is not, on the face of the text, an answer.
Section 3(h) does exempt three categories, among them a direct transfer between two individuals without an intermediary, and any transaction by means of a software or hardware wallet facilitating an individual’s own custody. Cage operators will notice the second. Whether a deposit into a house-controlled address sits inside it is a legal question this desk will not answer. The same instinct — treat the payment layer as the soft target — ran through the case when Florida’s gambling complaints named the payment processors.
One number is worth keeping. Section 3(a) makes it unlawful for anyone other than a permitted payment stablecoin issuer to issue a payment stablecoin in the United States, and knowing participation carries a fine of not more than $1 million per violation, up to five years’ imprisonment, or both. Whether any given token’s issuer clears the Act’s bar, in either direction, is not established by anything we could open, and we will not guess it.
As ever: the losses at the table are real money, the token it is denominated in moves on its own, and none of this is financial advice.
