Example:
There is nothing you can do to "fix" a CDO, to make it liquid,
other than to standardize the terms and trade it on an exchange.
The liquidity gridlock prevailing in the secondary market for CDOs
is the normal situation for such unique and entirely opaque
instruments, whereas the past illusion of liquidity was abnormal,
a byproduct of the "irrational exuberance" described by Greenspan
himself. Buy Side investors accepted the fallacy of liquidity -- until
they asked the Sell Side dealers to bid on the paper. That's when
the current trouble really began.
