Federal Reserve Master Accounts

The Senate Banking Committee’s CLARITY Act faces a markup vote Thursday under unprecedented amendment pressure, with over 100 proposed changes filed and a direct clash emerging between banking interests and crypto advocates over stablecoin yield rules. For institutional investors, the bill’s fate will determine whether crypto firms can access core U.S. banking infrastructure and whether stablecoins can offer yield, two regulatory uncertainties that currently constrain institutional custody and treasury management strategies.

• Senator Elizabeth Warren alone filed more than 40 amendments, including one to bar the Federal Reserve from issuing master accounts to crypto companies entirely.
• American Bankers Association members sent over 8,000 letters to Senate offices in less than a week demanding changes to stablecoin yield provisions.
• More than 100 total amendments filed ahead of Thursday markup, nearly matching the 137 proposed before a canceled January vote.

• 40+ Amendments filed by Elizabeth Warren alone, targeting Fed access and ethics guardrails.
• 8,000 Letters sent by bankers to Senate in under one week opposing yield rules.
• 100+ Total proposed amendments filed before Thursday’s Banking Committee markup vote.

The Senate Banking Committee will proceed to markup Thursday on the CLARITY Act facing the heaviest amendment barrage in recent committee crypto legislation. Senator Elizabeth Warren filed more than 40 separate amendments before Tuesday’s 5 p.m.

ET deadline, while the American Bankers Association mobilized over 8,000 letters from member institutions to Senate offices in less than seven days demanding substantial revisions to the bill’s stablecoin yield framework.

The scale of opposition signals that the CLARITY Act, intended to establish federal oversight of crypto markets while protecting banks’ market position, has become a flashpoint for three competing interests: banking regulators seeking to constrain crypto market infrastructure, traditional financial institutions fighting yield-bearing stablecoin competition, and digital asset firms arguing they require stable regulatory clarity to operate.

The total amendment count going into Thursday remains fluid, but sources tracking the filing process confirm more than 100 proposed changes now sit before the committee.

In January, when a prior CLARITY Act markup was scheduled, 137 amendments had been filed before that vote was canceled, suggesting this week’s amendment surge represents the most significant legislative challenge the bill has faced.

The sheer volume indicates that negotiators have failed to broker consensus before the committee floor debate, leaving contentious issues unresolved that will now require live markup votes.

Warren’s Master Account Amendment Would Sever Crypto Firms From Banking System Core

Among Warren’s 40-plus amendments, one stands out as potentially the most consequential for institutional market structure: a provision that would bar the Federal Reserve from issuing master accounts to crypto companies. Master accounts represent the core infrastructure through which all banks and many financial institutions access the Federal Reserve’s payment and settlement systems.

Denial of these accounts would effectively isolate crypto firms from the U.S. banking plumbing, forcing them to route all transactions through correspondent banks, adding cost, latency, and regulatory risk to custody operations, trading infrastructure, and stablecoin settlement.

For institutional investors evaluating crypto custody providers and trading venues, loss of direct Fed access would fundamentally alter the operational and counterparty-risk profile of those platforms. Institutions have been gradually moving assets into crypto custody solutions with direct bank settlement access; Warren’s amendment would reverse that trajectory by policy.

Warren has also filed amendments targeting conflict-of-interest provisions, arguing in a post on X that the bill “lacked ethics guardrails” and pointing to concerns about President Donald Trump’s meme coin holdings and crypto-related business activities. “No bill should move through the Banking Committee without real ethics guardrails,” she wrote.

No bill should move through the Banking Committee without real ethics guardrails.

Senator Elizabeth Warren

Warren’s framing reflects a broader Democratic argument that the CLARITY Act was stalled in recent weeks specifically because Democrats demanded conflict-of-interest language tied to Trump’s personal crypto exposure before backing the legislation.

Reed and Smith’s Joint Amendment Forces Republicans Into Bank-Versus-Crypto Vote

A second major amendment, filed jointly by Senators Jack Reed of Rhode Island and Tina Smith of Minnesota, proposes incorporating the American Bankers Association’s requested changes to stablecoin yield language directly into the bill. This amendment is strategically structured to force senators into a single binary choice: protect stablecoin rewards or align with banking industry requests.

For Republicans, who have traditionally maintained support from both the banking lobby and crypto constituencies, this amendment creates acute political tension, a live floor vote requiring them to choose which industry to prioritize.

Reed filed a separate amendment that would prohibit crypto from being used as legal tender, including for tax payments. This directly contradicts a bill introduced last year by Representative Warren Davidson that would have authorized Bitcoin acceptance for federal tax obligations.

The competing visions reflect deeper disagreement about whether crypto should integrate into existing dollar-denominated payment systems or remain categorically separate.

Journalist Brendan Pedersen observed that the Reed-Smith amendment design forces what may be the markup’s most uncomfortable vote for the Republican caucus.

Banking Industry Mobilizes 8,000-Letter Campaign While Crypto Advocates Counter With Scale

The American Bankers Association’s decision to mobilize member institutions to send over 8,000 letters to Senate offices in less than a week underscores the banking industry’s view that CLARITY Act stablecoin yield provisions represent an existential competitive threat.

Stablecoins offering yield, typically by lending reserves or routing them into money-market funds, create an alternative to traditional savings accounts and money-market funds that banks depend on for funding. By packaging yield into stablecoin protocols, crypto platforms can attract institutional treasury capital that might otherwise rest in bank deposits or bank-managed money-market funds.

Stand With Crypto, the leading crypto industry advocacy organization, responded on Tuesday with competing numerical claims designed to demonstrate grassroots support for the bill.

The group reported that its advocates had called Congress 8,000 times and sent 300,000 emails over recent months to defend stablecoin yield provisions, and had contacted lawmakers nearly 1.5 million times overall in support of CLARITY Act passage. The parallel 8,000-contact figure, matching the bankers’ letter count, appeared deliberately chosen to signal parity in mobilization capacity.

Crypto advocates are framing the banking industry’s campaign as an anticompetitive attempt to block yield-bearing stablecoins rather than genuine prudential concern.

Senator Bernie Moreno has accused banks of trying to “kill stablecoins that would let everyday” Americans access competitive returns, language suggesting the banking lobby’s position reflects protective regulation rather than consumer protection.

This framing, if it gains traction during markup, could shift the debate from prudential questions about stablecoin risk to competition-policy questions about whether banks deserve regulatory protection from digital asset market entrants.

The markup vote Thursday will reveal whether the 100+ amendments drive compromise language, fragment the bill into competing versions that require subsequent reconciliation, or produce a vote so close it raises questions about the bill’s viability this year. Warren’s master account amendment, the Reed-Smith binary choice on yield, and the banking letter campaign have all created decision points that senators cannot avoid on the markup floor. Watch for whether Republican leadership attempts to table amendments or allow them to proceed to individual votes, that choice will signal whether CLARITY Act passage remains a priority for the GOP-controlled committee or whether the competing pressures have made progress conditional on major structural changes to the bill’s stablecoin provisions.
