State regulators split over stablecoin safe harbor as GENIUS Act approaches
Key points
- The GENIUS Act takes effect on 18 January, but no state is expected to have SCRC approval by that date, creating an immediate compliance gap for state-licensed stablecoin issuers.
- CSBS, writing with three other state organisations, is requesting safe harbors covering the SCRC review period, the 180-day deficiency-cure window, conditional certifications promising legislation by January 2028, and temporary losses of recertification.
- NYDFS, which has historically overseen the largest US stablecoin issuers, argues no safe harbor is needed under the statute's existing text, and frames Treasury's foreign-stablecoin rules as the more significant risk.
- Treasury missed its own July 2026 deadline for finalising the principles states must satisfy for "substantially similar" certification, leaving states without a benchmark to file against.
- Mastercard submitted separate comments asking Treasury to define when a service provider crosses the threshold into classification as an unlicensed stablecoin issuer.
A fault line has opened among US regulators over how stablecoin issuers operating under state licences should be treated when the GENIUS Act takes effect on 18 January. The Conference of State Bank Supervisors (CSBS), writing alongside three other state organisations, has asked the Treasury to create multiple explicit safe harbors covering the period when state regimes are awaiting approval from the Stablecoin Certification Review Committee (SCRC), the 180-day window states have to remedy deficiencies after a denial, and situations where a state has not yet enacted legislation but files a conditional certification pledging rules by January 2028.
The New York Department of Financial Services (NYDFS) disagrees with the premise. It contends no safe harbor is necessary because the statute already permits continued operations, and its own reading of the Act is that the more pressing problem is Treasury’s proposed rules being too permissive toward foreign stablecoin issuers. The divergence matters operationally: Treasury’s current proposal extends a pending-application safe harbor to federal applicants but only poses the question of equivalent protection for state issuers without resolving it.
The timing problem sits underneath the entire dispute. States must self-certify that their regulatory framework is “substantially similar” to the federal standard, and the SCRC then reviews that certification. States have up to a year from the effective date to file, but Treasury has already missed its own July 2026 statutory deadline for publishing the principles that states are supposed to measure themselves against. No state is expected to hold SCRC approval by January. Without safe harbors, CSBS warns that issuers will migrate to the federal pathway through the Office of the Comptroller of the Currency (OCC), effectively sidelining the state route that Congress built into the Act. Mastercard has submitted separate comments raising a distinct concern, asking Treasury to clarify when a service provider’s activities tip over into classification as an unlicensed issuer.
