Sen. Elizabeth Warren is accusing Federal Reserve Chair Jerome Powell of doing the financial industry's bidding by considering changes to regulations aimed at increasing capital requirements for large American banks. Warren expressed disappointment that Powell may be delaying and watering down the Basel III Endgame regulations after meeting with big bank CEOs. The proposed rules, in response to the 2008 financial crisis, are seen as critical in light of recent failures in the banking sector. Bank CEOs argue the increases are too aggressive and would impact lending. Powell has indicated potential changes to the regulations following industry pushback, sparking Warren's criticism. She urges Powell to allow a vote on the original proposal by the end of the month to prevent a financial crisis. The fate of the rules may be influenced by the upcoming U.S. elections.
