The Consumer Financial Protection Bureau (CFPB) has proposed to block banks and other financial institutions from one potential source of new junk fee revenue – fees on transactions declined right at the swipe, tap, or click. The proposed rule would prohibit non-sufficient funds (NSF) fees on transactions that financial institutions decline in real time. These types of transactions include declined debit card purchases and ATM withdrawals, as well as some declined peer-to-peer payments. The CFPB’s proposal is part of the agency’s proactive approach to protect consumers, and it would cover banks, credit unions, and certain peer-to-peer payment companies.
