The Senate Banking Committee opens markup on the CLARITY Act today at 10:30 a.m. EST with more than 100 amendments on the table, shifting a market structure bill into a multi-front debate over stablecoin yields, Federal Reserve payment access, and the legal status of digital assets. The deadline for filing changes has passed, and the amendment volume alone guarantees an extended session that could rewrite the bill before it reaches a committee vote.
Crypto journalist Eleanor Terrett reported that Senator Elizabeth Warren filed more than 40 amendments, and Senator Jack Reed introduced a proposal that would prohibit cryptocurrencies from being used as legal tender. Separately, the American Bankers Association has driven more than 8,000 letters to Senate offices since Friday, pressing lawmakers to tighten the stablecoin yield compromise. The result is a markup that will test whether the crypto industry’s push for a federal framework can survive a co-ordinated bank-led effort to narrow access.
The pile of changes recalls the 137 amendments reportedly filed before a January markup that was later abandoned. This time the committee is moving forward, and the amendments from Warren and Reed signal that the bill’s Senate path will face resistance well beyond the Banking Committee room.
The January markup collapsed after a similar amendment flood. Lawmakers appear to be using the same tactic again–forcing concessions, delaying a vote, or recording opposition that will later surface during a floor debate. For traders, the critical variable is whether the committee can advance a bill that still contains the core market structure provisions crypto firms want, or whether the amendments hollow out those provisions.
The Banking Committee can report the bill on a party-line vote if Republicans stay unified. That would send it to the full Senate, where 60 votes are needed for passage. Amendments adopted in committee will shape the whip count. Even amendments that fail can preview floor fights, giving traders a map of which crypto subsectors carry the highest legislative risk.
Warren filed more than 40 amendments, making her the most active lawmaker in this round. Two themes dominate: cutting off crypto firms from the Federal Reserve’s payment system and inserting conflict-of-interest rules aimed at elected officials and their families.
One amendment would prevent the Federal Reserve from issuing master accounts to crypto companies. A master account gives an institution direct access to the central bank’s payment system–the backbone of dollar clearing. Without it, a crypto firm must route dollar transactions through intermediary banks, adding cost, latency, and counterparty risk. If this amendment survives, the CLARITY Act would create a federal regulatory framework for digital assets while simultaneously blocking the regulated firms from the most efficient settlement channel.
Key insight: A master account ban would force crypto exchanges and stablecoin issuers to remain dependent on partner banks, preserving the bottleneck that has already produced debanking episodes.
Warren has warned that the latest CLARITY Act draft could benefit Trump-linked crypto ventures if conflict rules are not added. She argued that the bill fails to stop elected officials or their families from profiting from digital asset businesses. The amendment would insert ethics language that could complicate equity structures at crypto firms with political connections. For publicly traded crypto equities or tokens tied to ventures with political exposure, this introduces a new headline risk.
Senator Reed filed a separate amendment that would prohibit cryptocurrencies from being used as legal tender, including for tax payments. The measure directly contrasts with a bill introduced last year by Representative Warren Davidson, which sought to allow Bitcoin tax payments. Reed’s proposal would foreclose that option at the federal level, removing one potential utility narrative for Bitcoin and other layer-1 assets.
The practical effect of a legal tender ban is limited: no U.S. jurisdiction currently treats Bitcoin as legal tender, and federal tax payments in Bitcoin remain a niche proposal. The amendment matters more as a signal that Congress is willing to preempt state-level legal tender experiments. That could chill legislative efforts in states such as Texas or Florida, where lawmakers have explored digital asset integration.
Reed and Senator Tina Smith also filed an amendment tied to stablecoin yield restrictions. According to Punchbowl News, the proposal would add banking industry language aimed at rewards that are “substantially similar” to deposit interest. That phrasing targets stablecoin issuers and platforms that offer yield on dollar-pegged tokens without a banking charter.
The amendment places senators between two competing policy positions. Crypto firms want room to offer activity-based rewards. Banks want Congress to stop stablecoin issuers from offering products that resemble bank deposits while escaping bank regulation. The “substantially similar” test would give regulators broad discretion to classify yield-bearing stablecoin products as unlicensed deposit-taking, a designation that could force business model changes at major stablecoin issuers and at decentralized finance protocols that integrate stablecoin yield.
Outside the committee room, banking groups are running a parallel pressure campaign. Sources say American Bankers Association members have sent more than 8,000 letters to Senate offices since Friday, directly targeting the stablecoin yield compromise.
The letter campaign focuses on the same language Reed and Smith are addressing through amendments. Banks argue that any yield on stablecoins–whether labeled a reward or interest–competes with bank deposits and should face the same regulatory capital and insurance requirements. The 8,000-letter volume signals a co-ordinated effort to make the yield question the bill’s central flashpoint.
Banking groups are pressing three points: yield language that treats stablecoin rewards as deposit-like, restrictions on Fed payment access for non-banks, and a prohibition on any advantage that lets crypto firms operate outside traditional banking oversight. The CLARITY Act, as originally drafted, was seen as more permissive. The amendment process is the vehicle banks are using to narrow it, reinforcing their gatekeeper role in the dollar payment system.
The amendment stack creates a clear set of relative impacts across the crypto sector, depending on which proposals survive the markup.
If the Reed-Smith “substantially similar” language is adopted, stablecoin issuers that offer yield–either directly or through partner platforms–face an immediate compliance question. The read-through extends to DeFi protocols where stablecoin yield is a core product. A restrictive yield rule would push yield-seeking capital toward regulated bank products or toward offshore stablecoin alternatives, reducing total value locked in U.S.-facing protocols.
A master account ban would keep exchanges and custodians reliant on intermediary banks for dollar clearing. That preserves a single point of failure that has already caused service disruptions when partner banks cut ties. The read-through is negative for any exchange or custodian that has lobbied for direct Fed access as a way to reduce settlement risk and cost.
A legal tender prohibition removes a potential adoption catalyst, though the practical impact remains low. The measure signals that Congress will likely block any state-level push to accept Bitcoin for tax payments, reducing the chance of a policy-driven demand narrative emerging in the near term.
Banks that custody digital assets or process crypto-related payments stand to benefit if the amendments restrict direct Fed access for crypto firms and tighten yield rules. The proposals would preserve banks’ intermediary function, reinforcing the value of trust bank charters and custody partnerships. The read-through is modestly positive for banking institutions with digital asset custody units, though no individual firm is named in the source.
The markup is not a final vote, however it is the first real-time test of how the Senate Banking Committee balances crypto industry access against banking industry demands. The amendment debate will surface the specific language that could survive a floor fight, giving traders a concrete set of policy risks to price.
If the committee adopts amendments that restrict Fed access or tighten yield rules, expect a negative reaction in tokens tied to U.S.-based exchanges and stablecoin protocols. If those amendments fail and the bill advances largely intact, the relief trade could lift the same names. The markup’s duration and the margin on key amendment votes will provide the signal.
Even a clean committee vote does not guarantee Senate passage. The bill needs 60 votes on the floor, and the amendments preview the objections that will surface during floor debate. Traders should track which amendments attract bipartisan support, as those are the provisions most likely to survive in a final compromise.
Risk to watch: A markup that runs long and produces multiple adopted amendments hostile to crypto access would reset expectations for any pro-crypto legislation in this Congress, weighing on sector valuations beyond the immediate names.
The 8,000-letter lobbying surge is a measurable input. If the letter count continues to rise through the markup, it signals that banks are willing to spend political capital to shape the stablecoin yield outcome. That raises the odds that some form of yield restriction makes it into the final bill, even if the committee rejects the Reed-Smith language this week.
The CLARITY Act markup is the first major legislative test for crypto market structure in the current Congress. The amendment volume, the bank lobbying push, and the specific policy flashpoints–Fed access, stablecoin yield, legal tender–make it a sector-wide event, not a single-stock catalyst. Traders should watch the markup for the language that survives, not just the final vote count.
