Senate Republicans release expanded CLARITY Act bill

TLDR

Senate Republicans have released a significantly expanded, 630?page version of the Digital Asset Market CLARITY Act ahead of a crucial September 15 Senate vote.

1. The new draft tightens rules on non?decentralized DeFi protocols, narrows DeFi to spot digital commodities, and clarifies credit unions authority to engage in crypto.
2. The bill would create a clearer split between SEC and CFTC oversight and formal federal rules for exchanges, but ethics and stablecoin provisions remain the main political blockers.
3. A cloture vote on September 15 needs 60 senators; without Democratic crossover, the bill and broader U.S. crypto market?structure reform could stall for years.

Deep Dive

1. What Changed In The Expanded Text

Republicans, led by Sen. Cynthia Lummis, have circulated a revised 630?page substitute amendment to H.R. 3633, the Digital Asset Market CLARITY Act, incorporating more than 100 Democrat?requested changes, while keeping core pillars intact. The updated language requires non?decentralized finance trading protocols (platforms where identifiable people or entities can materially control or change the protocol) to register with the CFTC, and directs CFTC and Treasury to write implementing rules, as described in the revised bill summary.

DeFi provisions are now explicitly scoped to spot and cash digital commodity transactions, partly to address tribal concerns about blockchain prediction markets. The text also clarifies how credit unions can offer crypto services under National Credit Union Administration oversight, and it preserves elements like the Blockchain Regulatory Certainty Act and a ban on interest or yield on payment stablecoins.

2. Why It Matters For Crypto Market Structure

Substance-wise, the CLARITY Act aims to resolve one of cryptos biggest uncertainties: who regulates what. It would preserve SEC jurisdiction over securities and fundraising, while expanding CFTC authority over spot digital commodities and intermediaries, including exchanges and brokers, as outlined in detailed overviews of the Acts SECCFTC split and ancillary assets concept.

For DeFi, the draft distinguishes between infrastructure and controlled services, seeking to protect developers and validators while requiring registration for protocols with real managerial control. It also moves toward federal, rather than patchwork state, oversight of trading venues, with stronger customer protection and anti?money?laundering requirements. Credit unions gain clearer room to handle tokenized deposits and crypto products, which could broaden mainstream access to digital assets if the bill passes.

3. What Happens Next And Key Obstacles

The immediate test is a cloture vote scheduled for September 15 at 2:15 p.m. Eastern Time. This is a procedural vote to begin debate, not final passage, but it requires 60 votes. With Republicans holding 53 seats, they need at least seven Democrats or independents, and reporting indicates no public Democratic endorsements yet.

Ethics language is the main stumbling block. The current provisions, enforced by the Justice Department and expiring in January 2029, bar officials and spouses from issuing or sponsoring digital assets, but critics say this is too weak given President Trumps sizable crypto holdings tied to projects such as World Liberty Financial and the TRUMP meme coin, as noted in recent coverage. Disputes over stablecoin yield and illicit?finance safeguards also remain live.

Conclusion

The expanded CLARITY Act is the most detailed attempt so far to give U.S. crypto markets a federal rulebook, especially for DeFi, exchanges, and token classification. For now, it is still only proposed legislation, and the September 15 cloture vote will decide whether it moves into full debate or stalls. Crypto users should watch both the vote outcome and any amendments on ethics, stablecoins, and DeFi registration, as those details will determine how burdensome or enabling the eventual framework could become.
