The Consumer Financial Protection Bureau finalized a rule on Thursday to limit banks' overdraft fees, potentially saving U.S. consumers $5 billion annually. The rule allows banks to charge $5 for overdrafts, down from an average of $35, or align fees with lenders’ costs while requiring interest rate disclosure for overdraft-related loans. The rule applies to institutions with $10 billion or more in assets and will take effect next October. It faces opposition from banking groups and uncertainty over enforcement, as a potential Trump-appointed CFPB head in 2025 may not support the Biden-era regulation.
