Senators led by Republican Cynthia Lummis are pressing the Treasury Department to establish a formal process for states to prove they can adequately supervise stablecoins. The request, tied to the GENIUS Act, targets a gap in how state-level oversight would factor into the federal framework.
The request to Treasury
In a letter to Treasury Secretary Janet Yellen, the group of senators argued that states need a clear path to demonstrate their supervisory capabilities. Without such a process, they warned, the GENIUS Act's aims could be undermined. The senators did not specify a deadline but urged the department to move quickly.
Why stablecoin oversight matters
Stablecoins have drawn increasing attention from regulators as their market footprint grows. The GENIUS Act, introduced earlier this year, would create a national standard for stablecoin issuers. But the senators worry that without state-level input, the law could create confusion or allow weak oversight in some jurisdictions.
Lummis, a vocal advocate for digital asset regulation, has long pushed for a role for states in the crypto landscape. The letter reflects a broader tug-of-war between federal and state authority over financial innovation.
The Treasury Department has not publicly responded to the senators' request. The GENIUS Act remains in committee, and lawmakers are still debating how to balance state and federal roles. For now, the senators are waiting on Treasury to outline a process — or explain why one isn't needed.
