Senator Cynthia Lummis, Republican of Wyoming, has pushed back against warnings that stablecoin legislation would trigger a flight of bank deposits, according to a Yahoo Finance report on the intensifying fight over the CLARITY Act in Washington.

Lummis, a longtime crypto advocate on the Senate Banking Committee, rejected the "deposit flight" argument that banking-sector lobbyists and some lawmakers have raised as Congress negotiates federal stablecoin and market-structure rules. The claim at the center of the dispute holds that if regulated payment stablecoins pay interest or offer yield-bearing features, retail and corporate customers would move balances out of insured bank deposits and into tokenized dollar instruments, shrinking banks' cheap funding base.

The CLARITY Act — a market-structure bill that would divide regulatory jurisdiction over digital assets between the Securities and Exchange Commission and the Commodity Futures Trading Commission — has become the legislative vehicle where these stablecoin provisions and banking concerns now collide. The debate runs parallel to the GENIUS Act, the stablecoin framework signed into law in 2025, which established federal rules for payment stablecoin issuers and reserve requirements.

Opponents of aggressive stablecoin provisions, including community-bank trade groups, have argued that widespread adoption of yield-bearing stablecoins could pull hundreds of billions of dollars out of the traditional deposit system. Banks fund lending largely through deposits, and a rapid shift of those liabilities to non-bank stablecoin issuers would force banks to replace that funding in wholesale markets at higher cost, potentially tightening credit availability.

Lummis disputes that framing. Her position, as reported, is that stablecoins expand the dollar's reach rather than cannibalize the banking system, and that interoperability between tokenized deposits and regulated stablecoins can serve the same customers without a zero-sum transfer of balances. She has previously argued that digital-asset legislation should position the United States as the issuer of choice for dollar-denominated digital instruments globally, a competitive argument against offshore stablecoin regimes.

The procedural context matters. The CLARITY Act passed the House in July 2025 with bipartisan support, but its Senate path has slowed as negotiators work through jurisdictional questions and banking-regulation carve-outs. Stablecoin language attached to or paired with the market-structure bill has become one of the sticking points, with deposit-flight concerns among the arguments deployed by skeptics of a permissive issuance regime.

The stakes for issuers are concrete. Circle, issuer of USDC, and other compliant operators already operate under the GENIUS Act's reserve and disclosure requirements. Whether Congress permits interest-bearing stablecoins, or restricts yield to banks and registered investment products, will shape the product roadmap for every issuer operating under U.S. jurisdiction — and determine whether banks can compete directly with tokenized-dollar products or must partner with issuers instead.

Lummis's rebuttal signals that Senate negotiators have not accepted the banking lobby's premise, and the dispute will test whether market-structure legislation can advance without amendments that would restrict stablecoin issuance to chartered banks. Senate Banking Committee action on the CLARITY Act remains the next procedural milestone, and the deposit-flight argument is likely to feature prominently in that markup.
