In December, the Federal Reserve approved new rules curtailing some -- but by no means all -- of the more egregious practices of the credit card industry. But, surprisingly, the rules are not scheduled to go into effect until July 2010. Why this 18-month long delay before making the banks clean up their acts? To hear the credit card companies tell it, curbing such practices as raising interest rates on pre-existing balances is no easy feat. American Express CEO Jud Linville calls compliance with the new rules "an enormously complex undertaking" and Citi Cards Executive VP John Carey warns of dire consequences, "not the least of which might be serious inconvenience for our cardmembers." You mean more seriously inconvenient than cardmembers having their interest rate jacked up to 29.99 percent if they miss a single payment?
