The principle, which may protect Americans billions in fees annually, is still unsure whether it will be implemented once President-elect Donald J. Trump assumes office. Federal authorities said the law, which the Consumer Financial Protection Bureau finalized on Thursday, may help protect Americans billion in costs annually, as it would reduce overdraft fees at big banks and credit unions. Whether it will remain in place once President-elect Donald J. Trump arrives to authority is questionable. The law would limit the costs that customers may be charged for when they use more money than they have in their bank balances. Big banks would have a variety of options, according to provincial officials. They could set their overdraft fees at a maximum of$ 5 or set them at a fee that more accurately represents the cost and loss. Additionally, they could handle loans as a line of credit and give similar disclosures, including appropriate curiosity prices. Despite many banks making moves to lower their overdraft fees, the average cost for each occasion is around$ 30, according to a recent Bankrate study. The rule would apply to institutions with more than$ 10 billion in assets, which includes about 150 of the nation’s roughly 9, 000 banks and credit unions, and take effect in October. Following the bureau’s proposal this month, banking business groups furiously criticized the rule. Some in the industry are expecting the Trump presidency, which took a pleasant approach to businesses during Mr. Trump’s second word, to try to move it up. Using a obscuring statute known as the Congressional Review Act, democratic lawmakers may even attempt to override it and other Trump administration rules. However, it is unclear whether they will be able to sway enough assistance to reverse some rules given the lean Republican majority in the House and the Senate next year.
