The Federal Reserve Board, the Office of Thrift Supervision and the National Credit Union Administration approved the regulation, which prohibits banks from certain practices like applying interest payments in ways that maximize penalties, and forces lenders to be more transparent about their billing practices.

The regulations mark an end to double-cycle billing, which averages out the balance from two previous bills. That means that consumers who carry a balance will no longer get hit with retroactive interest on their previous month’s bill. And credit card companies will no longer be able to raise the interest rates on pre-existing credit card balances unless a payment is over 30 days late.

Consumers will also be given a reasonable amount of time to make payments, and payments will be applied to higher-rate balances first, to reduce interest penalties and fees.

Credit card statements will clearly list the time of day that a payment is due, and any changes to accounts will be in bold or listed separately.

And, finally, no more universal defaults – a policy that allowed credit card issuers to increase the interest rate on one card if a customer missed a payment on another card.

But does this do to stop the uncontrolled spending by the card holders?
