The Treasury Just Put a Clock on Tether: Two Years to Cross the U.S. Line

The law the Senate can’t quite finish is quietly being built anyway — one agency at a time. On Monday, the U.S. Treasury Department published the first major implementing rule of the GENIUS Act, the federal stablecoin framework signed on July 18, 2025, and the proposal answers the question the industry has asked for a year: who counts as issuing a stablecoin “in the United States,” and who needs a license to do it. The 60-day comment clock starts now, the effective date of the law is around the corner, and for Tether — the offshore giant whose USDT powers roughly 61% of the global stablecoin market — the countdown just got a lot more visible.

This is the stablecoin track of American crypto policy moving while the market-structure track sits in neutral. The Senate is on recess until September 14, with the CLARITY Act’s procedural vote now set for September 15. But the Treasury doesn’t need Congress for this one. Here is what the proposal says, what it means for Tether, and why American holders should care about a comment period that most of them will never read.

The rule that finally defines “U.S. issuance”

The notice of proposed rulemaking (NPRM) published Monday establishes the core definitions of the GENIUS Act: what it means to issue, offer or sell a payment stablecoin in the United States, and under what conditions an issuer must obtain the federal license the law created. It follows the advance notice the Treasury issued last September and the joint FinCEN/OFAC anti-money-laundering and sanctions rule from April — but this is the piece the industry was waiting for, because it draws the jurisdictional line.

Treasury Secretary Scott Bessent framed it as an industrial policy play: the administration wants to move fast, he said, “to provide the regulatory certainty businesses need to innovate and grow in America, cement the role of the U.S. dollar as the world’s reserve currency, and keep America the crypto capital of the world.”

The most consequential part of the proposal is doctrinal. The Treasury says it studied the securities-law regimes as a reference point — but concluded that “the Act evinces a clear intent for payment stablecoins to serve as an effective means of payment and settlement, including across borders, and application of traditional investment rules to payment stablecoins may frustrate that goal.” In plain English: a stablecoin is not a security, it is a payment instrument, and it will not be regulated like one. That single paragraph tells exchanges, banks and issuers which legal regime they will live under for the next decade.

The public now has 60 days — until mid-October — to comment, and the proposal poses dozens of open questions that will only be settled after the comment period, then in a final rule that will take months more to draft.

A clock that is already late

The urgency is not hypothetical. The GENIUS Act gave federal regulators one year to produce implementing rules; that deadline passed last month without being met. The next marker is the law’s effective date, expected around January 18, 2027 — and it is unlikely every rule will be final by then. Regulators typically build transition periods into new regimes, and this law came with a big one built in: a three-year grace period, of which roughly two years remain, after which U.S. platforms may no longer offer stablecoins whose issuers have not satisfied all requirements.

Those requirements are the substance of the law: 1:1 reserves held in highly liquid assets (cash, Treasury bills under 12 months, insured deposits), regular independent attestations, registration with the OCC or a certified state regulator, and a ban on paying yield to holders. The consequence date lands around July 18, 2028 — the moment non-compliant tokens become untradeable on American soil.

Tether: $183 billion under the spotlight

No issuer has more at stake than Tether. USDT has roughly $183 billion in circulation — about 61% of a global stablecoin market the data firm Stablecoin Beat pegged at $298.4 billion on August 15. USDT has contracted 4.6% over 90 days, but it remains the most-used stablecoin on Earth.

Tether’s problem is twofold. First, its reserves: according to the company’s own disclosures, up to a quarter of USDT’s backing sits in assets that will not qualify under GENIUS Act standards — precious metals, loans and bitcoin — while the law demands the most liquid and safest assets available, essentially cash and short-dated Treasuries. Second, its domicile: Tether is incorporated in El Salvador, a foreign issuer, and how foreign issuers are treated is precisely one of the questions the Treasury’s proposal leaves open.

Lawyers diverge on the answer. Davis Polk reads the law as requiring foreign issuers to comply immediately with asset freezes and seizure orders once the statute is effective in January 2027, while granting roughly two years of transition for the rest — including OCC registration, which the firm describes as a “significant undertaking.” Paul Hastings previously read the statute as giving domestic and foreign issuers separate timelines. The ambiguity is real, and the market isn’t waiting for it to resolve: “Non-compliant stablecoins won’t be usable by U.S. institutions when the grace period expires in 2028, but we don’t expect the market to wait until then,” says Kevin Wysocki, head of policy at Anchorage Digital, the crypto bank that custodies Tether’s pre-compliance token USAT — launched last year but still marginal.

The CLARITY connection — and the Senate’s September date

The Treasury’s rulemaking lives in a delicate space next to the legislative fight that won’t die. The CLARITY Act, whose procedural vote is now scheduled for September 15 after the Senate returns on September 14, would rewrite parts of GENIUS — most notably its treatment of rewards programs for stablecoin holders on exchanges. Bank lobbyists and parts of the Democratic caucus oppose paying yield on stablecoins; the industry wants it legal. Until the Senate votes, issuers must plan against two regulatory texts that could contradict each other.

The bill’s odds are grim: Galaxy Research cut its 2026 passage probability to 10% last Friday, and the prediction-market contract trades near 18% Yes. But the Treasury’s proposal is a reminder that the executive branch can build a large part of the stablecoin regime without it — which is exactly why stablecoin issuers are watching the comment period more closely than the Senate calendar.

Europe already decided — and the contrast is the story

For American readers, the most instructive comparison is what the European Union did with its own framework, MiCA, now live since 2024–2025. Brussels imposed the same reserve and licensing requirements, then added something Washington refuses to contemplate: a cap on non-euro stablecoins at 1 million transactions or 200 million euros of daily volume — a monetary-sovereignty limit designed to protect the euro from dollar-pegged tokens.

The consequences are already visible: USDT was delisted from regulated European exchanges under MiCA, Tether’s EURT token was discontinued, and roughly fifteen stablecoins — including Circle’s EURC and issuers licensed in France, Luxembourg, the Netherlands, Finland, Malta and Germany — now hold MiCA authorizations. Two models are taking shape: Brussels contains the dollar stablecoin to defend the euro; Washington builds a framework whose stated purpose, in Bessent’s words, is to consolidate the dollar’s reserve status. Europe is the preview of what non-compliance looks like; the United States is the prize.

What to watch

The market, meanwhile, is trading the news as a green light rather than a threat. Bitcoin sits above $64,000 on Monday, its highest level since early August, buoyed by a wave of AI compute deals, and prediction markets have repriced the short term aggressively: the odds of bitcoin holding $60,000 on August 18 are near 100%, while the probability of trading above $64,000 on August 18 jumped 55 points in 24 hours to roughly 70% — from under 15% on Sunday. The reacceleration is real, even if the round-number thresholds make it look starker than it is.

For US stablecoin users, three dates matter: mid-October, when the comment period closes and the industry’s written positions become public; January 18, 2027, when the law’s effective date hits; and July 18, 2028, when non-compliant tokens lose access to American platforms. The decisive question — the one the Treasury deliberately left open — is how foreign issuers like Tether are treated in the final rule. The answer will decide whether USDT keeps a foothold on U.S. soil or becomes the world’s largest offshore token. In the meantime, the banks are already lining up for the trust charters that lead to issuance: the rush to the tokenized dollar has officially begun.
