Advanta has halted it's operations due to losses, and capitalone lost 1.4B in 2008 Q4. I'd bet (without looking at the financials) that the banks with substantial credit card operations currently lose money on those segments.
Advanta was a top 5 subprime lender. Recently, they've had huge delinquencies in their credit card operations.
Capital One has been expanding into regional banks and auto loans. Their yearly loss was $46MM, and the Q4 auto loan loss was $811MM. Capital One is also under pressure from card delinquencies.
Those on the edge, the once most profitable, are skipping payments and going into chargeoff status. This doesn't mean that "deadbeats" aren't profitable -- they just aren't AS profitable as those who carry a balance and make the minimum payment once were.
