This past summer's subprime meltdown involved about $900 billion in now-suspect securitized debt, reckless lending, and consumers who buckled under the weight of loans they couldn't afford. Now another link in the consumer debt chain - credit cards - is starting to show signs of strain.

...The doomsday scenario would play out something like this: Just like CDOs and other asset-backed securities, credit card debt is sliced, diced, and sold off again as packages of securities. Rising delinquencies would hurt not only the banks involved but the securities backed by the credit card receivables. Those securities would decline in value as consumers defaulted, leading to bank losses as well as portfolio losses in the hedge funds, institutions, and pensions that own the securities.
