Republican Senators Urge Regulators to Withdraw Bank Capital Proposal

On December 26, 2025, a bloc of 39 Republican senators, led by Senator Tim Scott of South Carolina, sent a letter to the Federal Reserve, the Federal Deposit Insurance Corporation and the Office of the Comptroller of the Currency urging the agencies to withdraw a controversial rulemaking commonly called the Basel III endgame. The senators said the July proposal, which would substantially raise capital requirements for the largest U.S. banks, should be scrapped because it could hinder lending and harm the broader economy.

The letter, signed by every Republican member of the Senate Banking Committee according to congressional sources, was delivered one day before representatives of the three agencies were scheduled to testify before the Senate Banking Committee. The timing underscored the urgency among Republicans to shape the agencies' public messaging and to press for a retreat or revision before the rulemaking moves forward.

Regulators designed the July proposal to better align U.S. capital rules with the global Basel III endgame framework, and under the plan the nation’s largest banks would be required to hold meaningfully more equity to cover potential losses. Independent estimates put the increase in required capital for the biggest institutions roughly between 5 percent and 20 percent depending on the bank. Lawmakers in the House and industry advocates have characterized the proposal as primarily targeting banks that hold more than $100 billion in assets.

Republican senators warned that forcing banks to retain more capital could reduce their capacity to extend credit, raising borrowing costs or tightening approval standards for loans. They argued the agencies had not provided adequate justification or analysis to show the benefits outweigh the economic tradeoffs, a central contention echoed in parallel actions by House Republicans. Members of the House Financial Services Committee released a letter and held a subcommittee hearing calling on regulators to withdraw the proposed requirements for banks with more than $100 billion in assets, and they said regulators "have not been forthcoming with the justifications or data" behind the rulemaking. The House committee also argued the proposals "lack sound rationale and economic analysis" and warned that "Your opaque approach raises serious questions about the long term impact these actions will have on our financial system and economy more broadly."

Spokespeople for the Federal Reserve and the Office of the Comptroller of the Currency declined to comment, and the FDIC did not respond to requests for comment. Agency testimony before the Senate Banking Committee the following day was expected to test whether regulators can defend the rule on both technical and political grounds.

Beyond the immediate regulatory fight, the debate has broader implications for communities and economic equity. Policy choices that reduce bank lending capacity can ripple into small business finance, affordable housing credit and consumer loans, areas that disproportionately affect low income neighborhoods and historically underserved populations. Advocates for stronger capital standards say higher buffers protect taxpayers and financial stability, while critics warn of collateral damage to credit access and local economies.

The outcome of the hearing and whether the agencies produce additional analysis or adjust the proposal will determine if the Basel III endgame proceeds on its current timetable, or whether regulators will recalibrate the balance between systemic resilience and credit flows to the real economy.
