01:09 PM EDT, 06/24/2025 (MT Newswires) -- (Updates with responses from a Federal Reserve spokesperson in the fourth paragraph and the Office of the Comptroller of the Currency in the fifth paragraph.)

US Senator Elizabeth Warren has criticized banking regulators' potential changes to the enhanced supplementary leverage ratio for banks, Bloomberg reported Tuesday, citing a letter that the lawmaker wrote to the regulators.

The changes, which include cutting a bank holding company's capital requirement under the rule to a 3.5% to 4.5% range from the current 5%, are set to be proposed after concerns that the rule constrained Treasuries market trading, the report said.

"It would be irresponsible to slash the eSLR in any economic environment," Warren said in the letter to Federal Reserve Vice Chair for Supervision Michelle Bowman, acting Federal Deposit Insurance Corp. chair Travis Hill and acting Office of the Comptroller of the Currency head Rodney Hood, according to the report. "It is especially reckless to do so given the numerous threats to the economy and the nation's financial system."

"We have received the letter and plan to respond," a Fed spokesperson said in a statement e-mailed to MT Newswires.

The OCC and the FDIC declined to comment when contacted by MT Newswires, while Warren didn't immediately respond to a request for comment.
