The U.S. Treasury didn’t wait. It dropped an interim final rule on September 30 that lets states kick off the stablecoin certification process even if their own regulations aren’t finished yet — a pretty significant move for an industry that’s been watching Washington fumble the regulatory handoff for years.
Why It Matters
This development signals a proactive approach by the U.S. Treasury to advance the stablecoin regulatory framework, potentially accelerating innovation and adoption in the sector. By allowing states to initiate the certification process independently, it could lead to a patchwork of regulations that fosters regional experimentation while also highlighting the need for a cohesive federal strategy in the evolving digital currency landscape. This move reflects an increasing recognition of the importance of stablecoins in the broader financial ecosystem and may influence how other jurisdictions approach similar regulatory challenges.
The rule went effective immediately. States can now submit initial certifications to a new federal body, the Stablecoin Certification Review Committee, without having every piece of their legislative framework locked down. That’s a real change from how these processes usually work, where incomplete filings basically go nowhere.
Not a rubber stamp, though.
What the Interim Rule Actually Does
The Committee is a federal body set up specifically to evaluate whether state stablecoin regimes meet Treasury’s standards. Under the new rule, states can file conditional or incomplete certifications to hit initial deadlines — but those filings don’t trigger the 30-day approval or denial clock. That clock only starts running once a certification fully complies with required procedures. So states get breathing room, but they can’t game the timeline by submitting something half-baked and calling it done.
There’s another catch. Certifications won’t be officially accepted until the Paperwork Reduction Act clears the associated information collection requirements. Treasury will announce when it starts taking submissions after that approval comes through. No date on that yet. Unclear when it actually happens.
The rule matters most for state-qualified payment stablecoin issuers sitting at or below $10 billion in outstanding stablecoin issuance. Those issuers can choose state-level regulation — rather than federal oversight — if their state’s regime clears Treasury’s substantial-similarity criteria and gets unanimous approval from the Committee under section 4(a) of the GENIUS Act. That’s a high bar. Unanimous means unanimous.
For the substantive review piece, states need to bring more than a conditional filing. They’ve got to provide an unconditional attestation, a detailed breakdown of how their framework lines up with Treasury’s similarity principles, and all the legal documentation that goes with it. It’s basically a full compliance package. The rule doesn’t finalize what “substantial similarity” actually means in practice — that’s still being worked out separately — but states are expected to build frameworks that either match or exceed federal benchmarks.
And the rule is clear on one thing: it doesn’t automatically hand out approvals or licenses. States get a path into the process. Individual issuers don’t get anything automatically. The two are separate.
GENIUS Act Timeline and What States Face
The initial certification deadline is January 18, 2028 — one year after the GENIUS Act’s expected effective date of January 18, 2027. But that date can move. Under section 20 of the Act, it can take effect either 18 months after enactment or 120 days after primary federal payment stablecoin regulators issue final regulations, whichever comes first. So if federal regulators move fast, the whole timeline compresses. States could find themselves scrambling to certify sooner than they planned.
Stablecoin regulation has been a long time coming at both the state and federal level. Several states have already been building out frameworks, and the stablecoin market itself has grown into a multi-hundred-billion-dollar segment of the broader crypto economy. The pressure to get this right — and get it done — is real.
Comments on the interim rule are open until November 30. Stakeholders can weigh in on the procedures before they get locked in further.
The Flexibility Play and Its Limits
What Treasury is basically doing here is threading a needle. States have wildly different legislative calendars. Some move fast, some don’t. A hard deadline with no flexibility would have left a bunch of states on the outside looking in while their legislatures were still in session or still drafting. The conditional filing option fixes that problem — sort of.
It’s not a free pass. States still need to get to an unconditional certification eventually. And the substantial-similarity question — how closely a state regime has to mirror federal standards — is probably the hardest part of this whole process. Treasury hasn’t finalized those criteria yet. That means states are essentially building toward a target that’s still moving. Risky.
For issuers, the math is pretty simple. If your state gets certified, you can potentially stay under state oversight rather than federal. That’s appealing to a lot of players who’d rather deal with a single state regulator than navigate a federal framework. But none of that happens unless the state actually gets through the Committee process, which requires unanimous approval. One dissenting vote and the whole thing stalls.
The Treasury’s September 30 rule sets the procedural groundwork. It doesn’t settle the big substantive questions. Those are still coming — and stakeholders have until November 30 to push back on the current framework before it hardens further.
The $10 billion issuance cap for state-qualified issuers stays in place.
Frequently Asked Questions
What does Treasury’s interim final rule allow states to do?
States can now submit conditional or incomplete stablecoin regime certifications to the Stablecoin Certification Review Committee before their own rules are finalized, letting them meet initial filing deadlines while continuing their legislative processes.
What is the certification deadline under the GENIUS Act?
The initial deadline is January 18, 2028, set one year after the GENIUS Act’s expected effective date of January 18, 2027, though the Act could take effect earlier depending on when federal regulators finalize their own rules.
