The Senate Banking Committee is heading into one of the most important crypto policy hearings in years after lawmakers submitted more than 100 proposed amendments ahead of the May 14 markup of the CLARITY Act.

While headlines have framed the amendment count as a sign of chaos, the process is more structured than it may appear. Senator Elizabeth Warren alone accounts for more than 40 of the filed amendments. This concentration reflects how much Democratic engagement on this bill is channeled through a single, organized legislative strategy instead of scattered individual objections. Most of the remaining proposed changes were filed by senators already participating in negotiations inside the banking committee, not by the full Senate.

Much of the debate now centers on how the proposed amendments could reshape stablecoin regulation, DeFi protections, and federal enforcement standards. The hearing will determine which revisions become part of the committee-approved version of the crypto market structure bill before it can move toward a broader Senate debate.

What the markup process actually means

A markup hearing is effectively the committee’s editing phase for legislation. Senators will debate the CLARITY Act section by section, introduce revisions and vote on selected amendments. Ultimately, they will decide whether the legislation should advance.

At this stage, the process is controlled primarily by members of the Senate Banking Committee. That means senators including Tim Scott, Elizabeth Warren, Cynthia Lummis, Thom Tillis, Bill Hagerty, Mark Warner, and Angela Alsobrooks are among the lawmakers directly shaping the bill.

Many of the filed proposals are technical adjustments, negotiated compromises, or political messaging amendments. They are not attempts to completely rewrite the legislation. They are intended specifically for the committee markup process itself, not for the Senate floor.

Why lawmakers filed so many amendments to the CLARITY Act

The large amendment count reflects unresolved negotiations around several controversial parts of the bill.

One of the biggest disputes involves stablecoin rewards. Hence, several of the most important amendments focus on tightening and clarifying the compromise language.

The current draft bans passive yield on idle stablecoin balances. Traditional financial institutions have warned that these bank deposit-style rewards could pull customers away from savings accounts. At the same time, the bill still preserves room for activity-based rewards tied to transactions or active use.

That is the specific legal line that determines whether products like Coinbase’s customer rewards program survive under the new framework. Senators have filed competing amendments to tighten or loosen that restriction. But critics on both sides question whether the distinction is workable in practice.

Lawmakers are also debating how decentralized finance platforms should be treated under federal law. The current bill text includes explicit protections for open-source software developers and node operators. These would shield them from securities liability for activities related purely to software development. Some senators want to strengthen those protections further. Others are pushing for stronger liability standards for protocol operators who exercise meaningful control over DeFi platforms.

Anti-money laundering requirements have become another major point of negotiation. The updated bill expands expectations around customer identification, suspicious activity monitoring, and sanctions compliance for crypto intermediaries.

Which amendments are likely to matter most

Not all proposed amendments will receive equal attention during the CLARITY Act markup hearing.

Committee leadership typically decides which amendments are formally debated, bundled into larger packages, or quietly withdrawn before votes occur. In many cases, senators file multiple versions of compromise language as negotiations continue behind closed doors.

Some proposals are considered serious bipartisan negotiations. Others are designed mainly to create political pressure or force recorded votes.

Ethics and banking amendments draw the most attention

Among the most closely watched proposals are amendments tied to ethics rules and potential conflicts involving public officials connected to digital asset businesses. The bill already contains language explicitly barring members of Congress and senior executive branch officials from issuing digital assets while in public service. Democratic lawmakers have pushed for additional disclosure standards and stricter restrictions tied to crypto ownership and commercial involvement.

Senator Jack Reed has filed an amendment that would go further still. He proposes to ban cryptocurrency from being used as legal tender entirely, including to pay taxes. While unlikely to pass in its current form, the amendment could force a recorded vote on the question of crypto’s broader role in the financial system.

The divide between the banking industry and crypto firms became clearer on May 9, when the American Bankers Association, the Bank Policy Institute, and the Independent Community Bankers of America jointly rejected the Tillis-Alsobrooks stablecoin compromise. The groups argued that the proposal still failed to prevent crypto firms from offering interest-like products. The rejection came just days before the markup, making the first amendment vote on stablecoin yield language a direct test of whether the banking lobby can fracture the CLARITY Act’s working majority.

Enforcement provisions remain another flashpoint

Another group of proposals centers on enforcement authority. Some senators want stronger Treasury and Justice Department tools tied to sanctions evasion, ransomware investigations, and illicit finance concerns involving decentralized platforms.

What happens after the committee vote

If the Banking Committee approves the bill, the revised version will advance to the full Senate for further debate.

At that stage, additional amendments could still be introduced by senators outside the committee. However, the markup hearing is widely viewed as the most important filtering stage. It determines the core structure of the legislation before leadership attempts a broader floor vote.

The outcome may also reveal whether lawmakers are close to forming a durable bipartisan coalition around crypto market structure legislation. How senators ultimately reshape the CLARITY Act during markup could determine whether Senate leadership can preserve support on both sides of the aisle through floor debate.

Even if the committee advances the bill, negotiations over stablecoin regulation, ethics provisions, and enforcement authority are likely to continue as the Senate moves closer to a full chamber debate later this year.

The outcome of the stablecoin yield amendments will be the clearest early signal. If the Tillis-Alsobrooks compromise survives intact, the bill has a credible path forward. If it is stripped or substantially weakened by a banking-aligned amendment, the crypto industry’s support could unravel. And with it, the broader legislative track for 2026.
