The most consequential crypto bill in American legislative history just got a lot more complicated. More than 100 amendments have been filed to the Digital Asset Market CLARITY Act ahead of the Senate Banking Committee’s scheduled markup on May 14, 2026, and Senator Elizabeth Warren is driving the largest single share of that opposition, with over 40 proposals of her own.
The amendment flood follows the committee’s release of a 309-page draft just after midnight on May 12, expanded from January’s 278-page version. That draft was supposed to reflect months of negotiation over stablecoin yield, DeFi liability, and developer safe harbors. What the amendment list reveals is how much of that negotiation remains unsettled.
Warren’s Priority Target: The Fed Master Account
Warren’s most aggressive proposal would block the Federal Reserve from granting master accounts to crypto companies. A Fed master account is not a technicality. It provides direct access to the central bank’s payment infrastructure, including real-time settlement through Fedwire and participation in the Automated Clearing House network. Several crypto firms have been actively pursuing that access, and the CLARITY Act’s framework was understood to clear a path for them. Warren’s amendment would close that path regardless of what the bill permits.
Her filings extend well beyond that single provision. Warren, the committee’s ranking Democrat, released a sharp statement alongside the bill’s unveiling, arguing that the draft included zero provisions to address conflicts of interest involving President Trump and his family’s crypto activities. That framing, conflict of interest as a threshold requirement rather than a negotiating point, sets up the most difficult dynamic heading into Thursday’s session.
The ethics standoff has been building for weeks. Senator Kirsten Gillibrand said at Consensus Miami 2026 that Democrats will not allow the bill to advance without an ethics section. White House crypto adviser Patrick Witt, also speaking in Miami, said the administration will accept rules that apply broadly, but will reject anything that singles out a specific officeholder. That gap has not closed. The amendment list is, in part, an attempt to force it to close publicly.
The Other Amendments That Matter
Senator Jack Reed filed 18 amendments of his own, including one that would entirely remove the Blockchain Regulatory Certainty Act provisions from the bill. The BRCA is the section that shields software developers who do not control user funds from being regulated as money transmitters. Its removal would fracture the developer and DeFi coalition that has been lobbying for the bill on the Senate floor. Reed also submitted language that would explicitly ban cryptocurrencies from serving as legal tender, including a prohibition on using crypto to pay taxes at any level of government.
Senator Mark Warner is targeting DeFi compliance directly. His amendment would establish a control test to determine when operators of non-decentralized finance protocols are subject to Bank Secrecy Act anti-money laundering obligations. That language reflects months of illicit finance negotiations that Warner has been central to, and it may represent a concession that some Democrats are willing to accept as part of a deal.
On the Republican side, Senator Bill Hagerty from Tennessee is seeking a ban on central bank digital currencies issued by the Federal Reserve, embedding that position into the market structure bill rather than pursuing it as standalone legislation.

The Stablecoin Yield Fight, Down to One Word
The stablecoin yield debate is technically specific in a way that matters enormously to the industry. The CLARITY Act’s current language would largely restrict bank-style passive interest on stablecoin deposits unless the issuer holds a bank charter. The contested detail is whether the bill’s restriction language should include the word “solely.” That single word determines whether yield-bearing stablecoin products are structurally compliant or categorically banned. Billions in projected product revenue hinge on it.
The American Bankers Association has not been quiet about where it stands. Since last Friday, ABA members sent more than 8,000 letters to Senate offices urging lawmakers to tighten the stablecoin yield compromise brokered by Senators Thom Tillis and Angela Alsobrooks. That volume of direct contact in under a week is significant. The Reed-Smith joint amendment, which incorporates the bank lobby’s preferred stablecoin yield language, is designed in part to force bank-friendly Republicans to choose sides publicly.
The CLARITY Act’s jurisdictional framework, giving the CFTC exclusive authority over spot and cash markets for digital commodities on decentralized blockchains while the SEC retains oversight of investment contracts, remains intact in the current draft. Most analysts consider that structural core settled. What is not settled is the surrounding politics.

What the Amendment Count Actually Signals
Triple-digit amendments at this stage are not simply noise. They map, with unusual precision, exactly where the bill’s drafters left negotiating room, and where they did not. The most contested provisions cluster around four areas: stablecoin yield treatment, DeFi protocol liability, digital asset mixer classifications, and developer safe harbors under the BRCA provisions.
Most of those amendments will not survive Thursday’s vote. A simple majority is needed to adopt or reject each one; Republicans currently hold the committee majority. But most analysts covering the session are focused less on the raw count and more on which amendments represent genuine concession offers in disguise. That distinction, not the volume, determines the bill’s final shape.
The CLARITY Act has survived two prior derailments, the January markup collapse and sustained opposition from banking and progressive coalitions throughout 2025. Bipartisan momentum is real: 78 House Democrats voted for the bill in July 2025, and the stablecoin reserve framework drew support from members who had previously opposed crypto legislation. The White House is still targeting July 4 for a presidential signature. That leaves roughly seven weeks to resolve disputes that have already stalled the bill twice.
Thursday’s markup begins at 10:30 AM Eastern in Dirksen Room 538. What comes out of that room will determine whether the most significant crypto regulation in American history gets enacted in 2026, or waits another cycle.
Frequently Asked Questions
What is the CLARITY Act and why does it matter?
The Digital Asset Market CLARITY Act is the primary U.S. crypto market structure bill, establishing how federal regulators oversee digital assets. It passed the House 294-134 in July 2025 and now sits with the Senate. If signed into law, it would divide regulatory authority between the CFTC and SEC, create a legal framework for stablecoins, and establish developer liability protections for DeFi. It is the most comprehensive crypto legislation Congress has attempted.
What is Senator Warren’s biggest objection?
Warren’s primary objection is the absence of ethics provisions addressing conflicts of interest involving public officials with crypto holdings, specifically President Trump’s family. Her most aggressive single amendment would block the Federal Reserve from granting master accounts to crypto companies, which would cut crypto firms off from direct access to the U.S. banking payment infrastructure regardless of what the bill otherwise allows.
What is a Senate Banking Committee markup?
A markup is a formal committee session where members debate and vote on proposed amendments to a bill before deciding whether to advance it to the full Senate floor. Each amendment is discussed and receives a vote; a simple majority is needed to adopt or reject it. If the committee votes to advance the bill, it moves toward a full Senate floor vote, where 60 votes are needed to overcome a filibuster.
What happens if the bill advances out of committee?
After the Banking Committee, the bill would move to the Senate Agriculture Committee for the CFTC-related provisions, then to the full Senate floor. It needs 60 votes to clear a filibuster, meaning bipartisan support is not optional. The White House has set a July 4 target for the president’s signature, though Senator Gillibrand has predicted early August. Polymarket currently puts signing odds at around 60%.
