Bipartisan Senators Demand Treasury Preserve State Control Over Stablecoin Regulation

Key Takeaways

• Bipartisan senators demand Treasury maintain state-level stablecoin regulation.
• GENIUS Act implementation creates uncertainty over state regulatory authority.
• Lawmakers demand adaptable framework for state-based stablecoin oversight.
• Treasury must provide detailed guidance on state certification procedures.
• State regulators need explicit pathway to supervise smaller stablecoin operators.

A coalition of US senators has mounted a significant challenge to Treasury’s approach to the GENIUS Act, demanding that state-level regulatory authority remain intact. The bipartisan effort centers on ensuring states retain meaningful power to regulate stablecoin issuers operating within their jurisdictions, particularly smaller entities.

Bipartisan Coalition Demands Treasury Clarification on State Qualification

Senator Cynthia Lummis spearheaded the bipartisan correspondence to Treasury Secretary Scott Bessent. The congressional delegation demanded specific details about how states can achieve qualification under the GENIUS Act. They emphasized that the certification mechanism must encourage state involvement rather than impose restrictive barriers.

The GENIUS Act establishes a regulatory framework enabling state-level supervision of payment stablecoin operators. It permits state regulatory authority when operators manage stablecoins valued at $10 billion or below. Participating states must implement regulations substantially aligned with federal requirements.

The congressional group criticized Treasury’s draft proposal for lacking comprehensive details about the qualification mechanism. This ambiguity threatens to leave states uncertain as they develop their respective stablecoin regulatory frameworks. The coalition demanded Treasury publish detailed written instructions including specific deadlines and procedural requirements.

Dual Banking System Becomes Central Concern

The lawmakers positioned their argument within the context of America’s dual banking structure. They emphasized that Congress intentionally crafted the GENIUS Act to safeguard state banking powers. Treasury should avoid implementing certification as an exclusive or time-limited opportunity.

Numerous states continue evaluating potential stablecoin legislation or associated regulatory frameworks. State legislative timetables vary considerably, with some jurisdictions operating under two-year legislative sessions. Given these realities, lawmakers insisted Treasury must accept certification applications on an ongoing basis.

The senators highlighted the annual recertification provision embedded in the GENIUS Act. They argued this mechanism demonstrates Congress’s intention for sustained collaboration between federal and state financial regulators. Treasury must maintain permanent access to the state regulatory pathway.

Market Cap Threshold Determines Regulatory Jurisdiction

The established market capitalization threshold would place the majority of stablecoin operators under potential state regulatory jurisdiction. Currently, only the most prominent stablecoins surpass the $10 billion benchmark. This elite category encompasses Tether, USDC, and USDS, based on market analytics referenced in recent reports.

Tether maintains its position as the dominant stablecoin by market value, placing it beyond the state regulatory pathway designed for smaller operators. USDC similarly surpasses the threshold and would require federal-level regulatory compliance. USDS, previously known as Dai, likewise exceeds the specified market capitalization limit.

The GENIUS Act thus establishes a bifurcated regulatory structure distinguishing between major and minor stablecoin operators. Smaller companies could pursue state charters provided their states obtain proper certification. This opportunity hinges entirely on Treasury’s finalized regulations and execution strategy.

Treasury Regulation Development Approaches Completion

Treasury initiated a public consultation process in April regarding state-level execution. The feedback window concluded on June 2. The agency is now developing its finalized regulation for official publication in the Federal Register.

President Donald Trump enacted the GENIUS Act in July 2025. The legislation established federal regulatory standards for payment stablecoins and their operators. It simultaneously created provisions for state regulatory systems that satisfy federal benchmarks.

The senators emphasized that Treasury must encourage responsible innovation while ensuring robust oversight. They argued that an adaptable certification process would preserve competitive dynamics in an expanding marketplace. Their correspondence now positions state regulatory authority as the pivotal issue in GENIUS Act execution.
