Stablecoins now the only federally regulated U.S. crypto asset

The Senate on Sept. 15, 2026 failed to reach the 60-vote threshold needed to proceed to debate on the Clarity Act, with the cloture motion losing 49–50. The vote halted a push to create a broader federal regulatory framework for tokens, decentralized finance and trading platforms, leaving stablecoins as the only crypto segment with a clear statutory path.

Republican Senators Susan Collins, Josh Hawley and Jerry Moran voted against the procedural motion, and Senator Thom Tillis cast a procedural no tied to a motion to recommit. Several Democrats who had worked on the bill, including Kirsten Gillibrand, Mark Warner, Cory Booker, Raphael Warnock, Ruben Gallego, Angela Alsobrooks and Catherine Cortez Masto, also voted not to move forward. Senate Republican leaders released a revised draft the weekend before the vote that added new ethics restrictions; those changes did not attract the remaining votes needed to open debate.

The Clarity Act passed the House in July 2025 by 294–134, but Senate negotiations stalled over ethics rules, decentralized finance, platform reward programs, illicit-finance safeguards and which federal agencies would hold authority. Majority Leader John Thune filed the cloture motion on Aug. 8 to set up the post-recess vote; a successful cloture vote would have only begun formal debate, not sent a final bill to the president.

With the bill stalled, the GENIUS statute that Congress already enacted remains the primary federal legal framework for stablecoins. GENIUS requires a license to issue payment stablecoins in the U.S. starting Jan. 18, 2027, and bars digital asset service providers from offering or selling non-compliant stablecoins to U.S. customers after July 18, 2028. Federal agencies are writing rules to implement those dates: the FDIC has proposed generally requiring permitted issuers to redeem stablecoins within two business days, and Treasury is working to define what counts as issuing, offering and selling in the United States.

One contested provision in the stalled Clarity Act was Section 404, a May compromise between Senators Tillis and Alsobrooks. Section 404 would have banned passive yield paid on stablecoin balances while allowing rewards tied directly to transactions or customer activity. It also included a temporary “circuit breaker” to let Treasury restrict rewards for up to 18 months if they risked drawing deposits from community banks with assets under $10 billion. Because the bill did not advance, that circuit breaker is not in force and GENIUS continues to focus on issuers, leaving open how affiliate-funded rewards programs are treated.

Regulatory action is already proceeding. Banking groups including the American Bankers Association, the Independent Community Bankers of America and 76 state banking associations urged tighter limits on deposit-like rewards in July. The Office of the Comptroller of the Currency has proposed rules that would treat certain issuer–platform revenue-sharing arrangements as attempts to evade statutory limits. Treasury is accepting public comments on GENIUS rulemaking through Oct. 19, 2026, with cross-border issues and foreign issuers such as Tether among topics expected in submissions.

Markets showed limited reaction to the Senate vote. Over the week after the vote, Circle’s shares fell about 5.8% while Coinbase’s stock was roughly flat. USDC’s circulating supply has ranged near $73 billion to $77 billion this year; earnings on reserves linked to short-term interest rates contribute to issuer and platform revenues.

Separate policy developments have advanced outside the stalled bill. The Securities and Exchange Commission approved a temporary Innovation Exemption permitting limited on-chain trading of tokenized national market system stocks on qualifying venues, and the House Ways and Means Committee moved forward legislation addressing digital-asset tax rules. Key remaining questions include whether Senate leaders will bring the Clarity Act back for another vote, whether yield-related language will be reopened, and how federal agencies will use rulemaking to address rewards and revenue-sharing.
