Got a bad credit deal? In 2011 you'll know why

Have you been offered a bad credit deal by a lender but don't know why? Starting in January 2011, banks will have to tell you why and give you free access to your credit report any time you're given less-favorable terms, according to final rules issued Tuesday by the Federal Reserve and the Federal Trade Commission.

Until that time, lenders don't have to explain why you're getting particular terms on any form of consumer credit, including credit cards, auto loans, mortgages and student loans. The rule change doesn't impact business lending.
