A Fed capital rules lawsuit filed on 10 September 2026 asks a Washington court to make the Federal Reserve withdraw its bank capital overhaul and start again. Better Markets brought the case against the Fed and Vice Chair for Supervision Michelle Bowman. The Federal Reserve has not responded.
What the Fed Capital Rules Lawsuit Asks the Court to Do
The remedies sought are narrower than the language around the case suggests. Better Markets, a non-profit group in the United States that advocates for financial regulation, filed in the US District Court for the District of Columbia, docketed as case number 26-3163 according to Banking Dive.
- A declaration: that the capital rulemaking is, in the complaint’s words, “fatally compromised”.
- Withdrawal: of the capital proposals issued in March 2026.
- A restart: of the rulemaking from the beginning.
- Recusal: of Bowman and any other Federal Reserve official involved in the conduct alleged.
The claims are brought under the Administrative Procedure Act, the United States statute that governs how federal agencies make rules, and under the Fifth Amendment’s due process protections. The argument is procedural: that the group was deprived of a fair chance to take part in the rulemaking, not that the capital numbers themselves are unlawful.
What Is Alleged, and What Has Been Established
Nothing in the complaint has been tested in court. These are allegations by a plaintiff, and no judge has made any finding about them.
Better Markets alleges that Bowman held private meetings with bank executives while the public comment period on the proposals was open, and coached them on what to say and what to leave out. The complaint says she pressed for feedback that was limited and specific and told bank leaders not to seek additional carve-outs. The group says the Fed disclosed other staff meetings with industry representatives but not these.
Dennis M. Kelleher, Better Markets’ co-founder, president and chief executive, announced the case at a National Press Club press conference on 10 September 2026. Banking Dive dated the filing itself to 11 September; American Banker reported it as filed on Thursday 10 September.
JPMorgan Chase chief executive Jamie Dimon and Goldman Sachs chief executive David Solomon are named in the complaint as people Bowman is said to have met. Neither is a defendant, and the complaint does not accuse either of breaking any law.
What Bowman Has Said
Bowman addressed the meetings before the lawsuit was filed. Testifying to the House Financial Services Committee in June 2026, she said she did not direct anyone about their comments for the rule and that the comment process is open, adding that she meets with a number of institutions and that doing so was her responsibility.
The Federal Reserve did not comment when the suit was announced. It and Bowman have 60 days to respond to the court.
The Capital Proposal at the Centre of the Case
The rules in dispute were issued on 19 March 2026 by the Federal Reserve, the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation, as three linked proposals implementing the Basel III standards agreed internationally in 2017.
The headline is counter-intuitive: one proposal raises capital for the largest banks while the package as a whole lowers it. Governor Michael S. Barr set out the combined arithmetic in a dissenting statement on the day.
| Group of banks | Change in common equity tier 1 requirement |
|---|---|
| Largest banks, Basel III proposal alone | +1.4% |
| Largest banks, G-SIB surcharge proposal | −3.8%, or about 33 billion United States dollars |
| Largest banks, whole package with stress test changes | −4.8% |
| Category III and IV firms | about −3% |
| Banks under 100 billion United States dollars in assets | almost −8% |
Common equity tier 1 capital is the highest-quality loss-absorbing capital a bank holds: ordinary shares and retained earnings, the buffer that takes losses first. Barr wrote that the proposals “would lower the common equity tier 1 capital requirements of the largest banks by 4.8 percent” and called the reductions unnecessary and unwise.
These figures apply to banks supervised in the United States. Capital rules in other jurisdictions are set by their own authorities, and consolidation among US lenders continues separately, as the EverBank and WaFd merger this month showed.
Where the Case Stands
As of 12 September 2026, the complaint has been filed and nothing else has happened. There has been no hearing, no ruling, no response from the defendants and no order affecting the rulemaking.
The comment period on the proposals ran until 18 June 2026 according to law-firm analyses of the filings, so the consultation the case concerns has already closed. Whether the agencies proceed to a final rule while the litigation is pending has not been announced.
Fed Capital Rules Lawsuit: Questions Readers Are Asking
Who Is Suing the Federal Reserve?
Better Markets, a non-profit advocacy organisation in the United States that campaigns for stricter financial regulation. It filed against the Federal Reserve Board and Vice Chair for Supervision Michelle Bowman.
Has a Court Found That Anyone Did Anything Wrong?
No. The case was filed on 10 September 2026 and no judge has ruled on any allegation in it. Bowman has said she did not direct anyone about their comments.
What Would the Capital Proposals Change?
Taken together with proposed stress test changes, they would lower common equity tier 1 capital requirements for the largest United States banks by 4.8%, according to Governor Michael S. Barr’s dissenting statement of 19 March 2026. Smaller banks would see larger proportional reductions.
What Happens Next in the Case?
The Federal Reserve and Bowman have 60 days from service to respond to the court. No hearing date has been reported as of 12 September 2026.
