WASHINGTON — NCUA and two other federal agencies are set to propose rules that would label "unfair or deceptive" practices such as charging interest on repaid debt and not providing adequate notice on when payments are due.

The rules also would prohibit debit card issuers from imposing an overdraft charge if the overdraft is caused solely by a hold placed on funds exceeding the purchase amount. Similarly, credit card holders won't be charged for exceeding their credit limit if this only occurs because a hold was placed on their account.

The NCUA, the Federal Reserve and the Office of Thrift Supervision are scheduled to issue a full text of the rules at 2:30 p.m. E.S.T. There will be a 75-day public comment period before the final rules are issued.
