WASHINGTON — The House voted on Wednesday to accelerate the enactment date of tough new rules for credit card companies after voters complained of a rise in interest rates and steep new fees. The bill, approved 331-92, would force lenders to comply with the new rules immediately unless they agree to freeze interest rates and fees.

The proposal’s chances in the Senate were dim, where several lawmakers worried that a short deadline would hurt the industry and limit the availability of credit. Nevertheless, investors seemed to take notice of the House rhetoric. Bank stocks tumbled in the last hour of trading on Wednesday immediately after the House vote, causing a late-day slump in the market. Democrats said the bill was a warning shot to lenders to stop price gouging.

“This is both real and a lesson to them,” said Rep. Barney Frank, D-Mass., the chairman of the House Financial Services Committee. Under the new law, lenders won’t be able to increase rates on existing balances suddenly unless a person is more than 60 days behind on a payment. Banks also couldn’t give cards to people under 21 unless a parent co-signed or the cardholder could prove they had the means to pay back the loan. To assuage concerns in the Senate that the restrictions were too onerous, Democrats gave banks nine months to prepare for the changes.

But lawmakers say that many credit card companies have used the grace period to increase rates. According to a recent Pew study, even the lowest interest rates offered on most bank cards have jumped by more than 20 percent since last year.

“The same companies that were in my office that claimed they needed months at least to make changes to their systems, apparently only needed in some cases days to find ways to raise interest rates and decrease credit limits on customers across the country,” said Rep. Dan Maffei, a New York Democrat.
