Senator Cynthia Lummis: Crypto Market Structure Bill ‘So Close’ After Stablecoin Yield Breakthrough

On March 18, 2026, Wyoming U.S. Senator Cynthia Lummis, a prominent advocate for cryptocurrency legislation in the United States Senate, provided a positive update on the progress of legislation concerning the reform of digital assets and how these are being regulated within a market framework at the D.C. Blockchain Summit held in Washington, D.C. The summit was organized by the Digital Chamber of Commerce and included speakers from government agencies, target industries, and compliance authorities discussing how blockchain technology impacts the economy.

According to Lummis, chair of the Senate Banking Committee’s subcommittee overseeing digital assets, it was anticipated that by now the digital asset industry would be celebrating a “victory lap”) because of the House’s passage of significant legislation in July 2025; however, unexpected delays to due to the subcommittee being unable to establish stablecoin regulatory guidelines has forced all progress back to 2026.

The House Victory in 2025 and Senate Roadblocks

The Digital Asset Market Clarity Act, known informally as the CLARITY Act or Clarity Act (H.R. 3633), was passed by the U.S. House of Representatives with bipartisan approval (294 to 134) on July 20, 2025. The legislation was designed to establish one federal regulatory system governing digital assets and define jurisdictional boundaries between the SEC and the CFTC, with the SEC regulating tokenized securities and the CFTC regulating things like Bitcoin and Ether, which are classified as commodities.

The measure was sent to the Senate after being assigned to the Banking, Housing, and Urban Affairs Committee in September 2025. Negotiations in the Senate continued through late 2025 into early 2026, with the Banking Committee drafting a bill entitled the Digital Asset Market Clarity Act and the Agriculture Committee drafting a bill called the Digital Commodity Intermediaries Act, but no clear way forward was produced by either committee.

Lummis was frustrated with the delays that followed the House’s passage of the GENIUS Act (Guiding and Establishing a National Innovation for United States ‘Stablecoin’), which was passed in 2025 and created standards for the payments made by stablecoins. It also left a number of different conflicts that had not been resolved.

The Core Issue: Stablecoin Yield vs. Rewards Dispute

The main reason for the delay was, according to Lummis, the heated debates banks and crypto firms had been having over stablecoin yields and rewards. The bank industry believes that allowing platforms to pay “interest” on stablecoin holdings will cause people to move their money away from traditional bank accounts and negatively impact smaller financial institutions by facilitating unsafe practices for consumers.

Firms that deal with cryptocurrency have claimed that there is a variation in the estimated value of the product or service being offered to customers based on a variety of factors, one of which is the way the individual user will be able to receive an incentive for utilizing said product or service (i.e., the amount of benefit received by user). The issuance of a yield or interest payment to investors from issuers of securities that are unable to pay out on their investments directly to third-party holders, as a consequence of the GENIUS Act; however, there remains significant interest and concern around whether cryptocurrency exchanges may be able to provide consumers with some form of reward or incentive without violating the overall intent of the GENIUS Act.

Negotiation efforts accelerated in early 2026 as the White House began to intervene and help bring the negotiation parties closer together. According to Senator Lummis, “multiple stakeholders who have been very entrenched on the yield versus reward issue are now working with both the White House and specific congressional representatives to arrive at compromise solutions."

Let me tell you about the what she says with certainty: "We believe that they are going to be able to reach a resolution." Reportedly, this will involve preventing developers from using terms related to banking transactions (like associates reward to deposit yields) or connecting rewards directly with asset holdings which has no transactional benefit. Transactional associated incentives may still be permitted and are seen as benefiting both parties—thereby accommodating each side without the total prohibition on rewards.

Lummis asked banks to "take the hard road and accept less than what they wanted," as both banks and companies were unlikely to get everything they wanted. Some individuals in the industry, such as Brian Armstrong, CEO of Coinbase, indicated a willingness to work with the banks.

Details on the compromise appear in reports from CoinDesk coverage of Lummis at the summit and American Banker analysis.

Path Forward: Senate Banking Markup in April

Because the yield issue would be resolved soon, Lummis expected the Senate Banking Committee to take quick action. She said they would hold a markup of the market structure bill "in the second half of April" after Easter break.

“We really are going to get it out of the Banking Committee in April,” she said, adding urgency: “This may be our only chance to get market structure done. I can’t be any clearer: The time for clarity is now.”

Should the Committee move the legislation forward, it may be addressed on the Senate Floor before 2026 ends. A senate approved version would have to reconcile with the House's CLARITY Act before receiving President Trump's approval.

Lummis stated the importance of clear regulations for the blockchain industry to encourage innovation, provide protection for consumers, and maintain the United States' competitive position in the blockchain industry. The lack of passage of legislation by mid 2026 would likely delay comprehensive legislation for years and potentially leave the industry to deal with disjointed agency rules.

Broader Context and Industry Reaction

In addition to the messages from SEC Commissioner Hester Peirce as well as Senate Banking Committee Chairman Tim Scott on the success of the GENIUS Act and the need for a clearer crypto environment, other notable pro-crypto senators such as Bernie Moreno (R-OH) delivered messages reinforcing this momentum.

Lummis’ comments were viewed by those who follow the industry as yet another step forward in breaking through months of gridlock. A final agreement on stablecoin language could lead to bipartisan votes being cast in the Senate (at least 60), thus giving the Senate a chance of passing the legislation.

As negotiations near completion (probably within the next few days or weeks), the focus will shift to committees next month and action being taken by those committees during April. 2026 may finally bring regulatory certainty to the crypto ecosystem, which has been looking for that certainty since the beginning of the rapid expansion of the crypto market.
