The Rulebook for Stablecoins Missed Its Own Deadline, and the Compliance Date Did Not Move
Six federal agencies were required to finalise the GENIUS Act rules by 18 July. They did not. The law still takes effect on 18 January 2027, which leaves issuers building to a rulebook that has not been written.

The GENIUS Act, signed in July 2025, gave the United States its first federal rules for payment stablecoins. It set a statutory deadline of 18 July 2026 for the six federal agencies involved to finalise the detailed rules, and an effective date of 18 January 2027 for the law itself.
The first of those dates passed without a coordinated final package. The second has not moved.
Why does a missed rulemaking deadline matter?
Because the two dates were designed to work as a pair, and only one of them slipped.
The six month gap between finalising rules and the law taking effect was the implementation window. It existed so that issuers, banks and custodians could read the finished requirements, adjust their reserves, reporting, disclosures and systems, and be ready on day one.
That window has now been compressed to whatever remains after the agencies publish. Every week of further delay is a week removed from the time firms have to comply, and none of it is removed from the obligation.
This is a familiar failure pattern in financial regulation and it is worth naming: the party that missed its deadline faces no consequence, and the parties that depend on its output absorb the whole cost.
What are firms supposed to do in the meantime?
Guess, carefully, and expensively.
A large issuer cannot wait. Building reserve management, attestation and reporting systems takes months, so the work has to start against the statute's text and against whatever proposals exist, in the knowledge that the final rules may differ.
That produces two bad outcomes. Firms build to their best reading and may have to rebuild. And the cost of doing that falls hardest on smaller issuers, who cannot absorb building the same thing twice. A rulemaking delay is, in practice, a competitive advantage handed to the largest incumbents.
How big is the thing being regulated?
Larger than most people following the debate realise, and no longer a crypto story in any meaningful sense.
Total stablecoin market capitalisation crossed 300 billion dollars in early 2026, reached about 322.6 billion in May, and sat near 316 billion in June, up from 308 billion at the end of 2025. The market added roughly 102 billion dollars during 2025, the year the legislation passed.
The number that matters more than any of those is a flow rather than a stock. In February 2026, stablecoins settled about 7.2 trillion dollars, surpassing the United States automated clearing house network for the first time.
ACH is the plumbing of American domestic payments: payroll, direct debits, bill payments. A category of privately issued digital dollars moving more value than that system is no longer an experiment on the edge of finance, whatever anyone thinks of it. We looked at the trust question this raises in what a 320 billion dollar market tests about money.
What is actually still unresolved?
The details that decide whether the regime works, which is why the delay is not merely procedural.
The hard questions in stablecoin regulation are specific: exactly what may be held as reserves and at what maturity, how frequently reserves must be attested and by whom, what happens to holders if an issuer fails and where they rank against other creditors, how foreign issuers are treated, and whether interest may be paid to holders.
Each of those changes the economics of the business substantially. Until they are settled, an issuer cannot know what its product is, which is the argument set out in our look at stablecoins as payment infrastructure and the risks in it.
Does this affect the Gulf?
Directly, because dollar denominated instruments are dollar denominated wherever they are used.
Regional adoption has been building on its own track, including dirham referenced issuance, which we covered in the move of dirham stablecoins into the mainstream. But the majority of the market is dollar backed, and the American rules will set the standard that other regimes are measured against, in the same way that American securities law shapes the rest of the digital asset conversation, as with the framework the Clarity Act would create.
What to watch
The publication itself, and how much runway is left when it arrives.
If the final rules appear in the autumn, firms have a difficult but survivable quarter. If they appear in December, the industry faces a compliance date it cannot realistically meet, and the plausible responses are all bad: an enforcement grace period that undermines the rules, a legislative extension that reopens settled arguments, or a January in which a large part of the market is technically non compliant.
The one thing that will not happen is the market pausing while regulators catch up. Seven trillion dollars a month does not wait.
