Senator Elizabeth Warren has strongly criticized Federal Reserve Chair Jerome Powell for considering changes to banking regulations that would impact the capital requirements for large American banks. Warren accuses Powell of acting in the interests of the financial industry rather than protecting Main Street Americans. She has urged Powell to reject the misleading claims of megabanks and to focus on what is best for the broader public. Warren's comments come as Powell evaluates potential changes to the Basel III Endgame regulations, which are designed to ensure that banks maintain sufficient capital cushions.
