The U.S. Treasury has issued a new rule that gives state regulators a practical route to meet an approaching federal deadline for stablecoin oversight, even if their own state-level rules are not yet complete. Under the measure, states may submit a conditional or incomplete certification by January 18, 2028, preserving their place in the federal review process while pending legislation or regulatory work is finished.

The rule was published in the Federal Register as an interim final rule taking effect September 30, 2026, and was issued by Treasury on behalf of the Stablecoin Certification Review Committee (SCRC). The SCRC is the federal body created under the GENIUS Act to determine whether a state's payment stablecoin rules are sufficiently close to federal standards to qualify for a state-supervised pathway. The interim final rule is available on the Federal Register website.

The GENIUS Act Framework

Under the GENIUS Act, a state-qualified payment stablecoin issuer may remain under state supervision instead of federal oversight, but only if its home state's rules are certified and approved by the SCRC. That option is limited to issuers with no more than $10 billion in consolidated total outstanding payment-stablecoin issuance. In practice, that cap reserves the state-supervised pathway for the smaller-issuer segment of the stablecoin market, while issuers above the threshold fall outside it regardless of how their home state's certification ultimately fares.

What the Treasury Rule Changes

Before this rule, it was unclear how states could apply to the SCRC if their own stablecoin laws were still being drafted. The interim final rule resolves that problem by separating two distinct steps: meeting the filing deadline and triggering a full substantive review.

A conditional certification, or even an incomplete one, is enough to satisfy the initial January 18, 2028 deadline. The arrangement functions much like reserving a spot in a queue. The state is saying: "We intend to have our rules ready, and here is our preliminary filing to hold our place." Treasury confirmed this reading in the rule text.

Holding that place, however, is not the same as receiving approval. The SCRC will not begin its substantive review of a state's regime until the state files a complete, unconditional certification. Only then does the formal evaluation clock start.

Why States Can File Before Finalizing Their Own Rules

Many states are still writing or debating their payment stablecoin laws. Requiring a finished statute before any federal filing would force states to either rush legislation or miss the federal deadline entirely, forfeiting the option of state-level oversight. Treasury's conditional-filing pathway avoids that bind.

A state can submit a preliminary certification that flags planned legislative or regulatory changes still in progress. That filing counts for deadline purposes under the Treasury interim final rule, even though the SCRC will not act on it until the state amends the submission into a complete package.

A separate timing gate is also worth noting. Although the rule took effect on September 30, 2026, Treasury said it will not actually accept any certifications yet. Acceptance is waiting on Paperwork Reduction Act approval for the information collection forms. Treasury will publish a notice on its website once that approval comes through.

What Conditional Certifications Mean for Stablecoin Oversight

The SCRC is chaired by the Treasury Secretary and also includes the Federal Reserve Chair (or a delegated Vice Chair for Supervision) and the FDIC Chair. That composition means any state certification will be evaluated at the highest levels of U.S. financial regulation.

Treasury's April 2026 proposal on substantial-similarity criteria, which spells out what a state regime must look like to pass SCRC review, remains in proposed form. The September interim final rule covers the mechanics of filing and review, not the substantive standards themselves — meaning states now have operative filing mechanics even as the substantive bar their statutes must clear exists only in proposed form. States filing conditional certifications will eventually need to meet those standards when they complete their submissions.

For stablecoin issuers, the practical implication is that the state-supervised pathway remains a future possibility rather than a currently available option. No state certification can receive SCRC approval until a complete unconditional submission is filed and reviewed. For issuers watching U.S. regulatory developments, the next concrete milestones are the Paperwork Reduction Act clearance that will open the filing window, followed by any state that converts a conditional filing into a complete one.

Interested parties have until November 30, 2026 to submit comments on the interim final rule.

For anyone holding stablecoins, the rule does not change anything immediately. It sets up the process that will eventually determine which state regulators can supervise smaller stablecoin issuers. The actual approvals, and the consumer protections that come with them, are still months or years away.
