Oh, if it were only just morgages...
What started out as morgages were, by the magic of "securitization," turned into bond-like securities; and in the process, many of the bad and even defaulted loans were transmaugrified into AAA-rated investments.
While housing prices continued to rise, everybody was happy and there were few defaults. But starting a couple of years ago, when the housing bubble burst and the mortgage default rate shot up, a bunch of banks found themselves holding very insecure securities, losing money hand over teakettle. The crash began among the lenders and spread to secondary markets (the MBSs and CDOs) and even tertiary markets (insurance underwriters like AIG). In short order, institutions all over the world found themselves holding pieces of paper whose value was impossible to determine -- which are referred to as toxic assets.
Anyway... gosh I feel bad.
Goodnight, folks!
