interest they paid on their ABCP liabilities. In the absence of consolidation of their
VIEs, sponsoring institutions did not have to worry about the effect of this ABCP
borrowing on their own leverage ratios or required capital adequacy ratios. Thus,
VIEs create huge amounts of CDOs and asset–backed securities, financing them
with ABCP so as to reap the spread.
As evidence (e.g., increasing default rates) that the U.S. mortgage market was in
trouble grew in the months leading up to August 2007, concerns about the
security of CDOs also grew. Matters came to a head when two hedge funds
operated by Bear Stearns Co. in New York declared bankruptcy because of CDO
losses. Shortly afterwards, on August 9, BNP Paribas, France’s biggest bank,
halted redemptions of three of its mutual funds because it was unable to
determine the fair value of the CDOs they contained. Several German funds
followed suit.
While CDOs and CDSs were, in theory, effective in dispersing risk, subsequent
events revealed serious problems in application, which came back to haunt the
creators of these financial instruments. Models used by financial institutions to
control risk had not anticipated the effects of lack of transparency concerning the
quality of the mortgages underlying CDOs. Once concern about mortgage
defaults appeared, lack of transparency contributed to investors’ lack of
confidence in all CDOs, leading to a situation whereby no one was willing to hold
them (an extreme version of the lemons problem, Section 4.6.1). Thus, liquidity
pricing ensued, leading to market collapse. Instead of dispersing risk, it seems
that CDOs and CDSs had merely transferred it from credit risk to liquidity risk.
Furthermore, as VIEs collapsed, their sponsors had to take the VIE’s assets back
onto their own balance sheets, creating huge writedowns.
Normally, asset writedowns would not be needed to the extent they were hedged
by CDSs. However, amounts of outstanding CDSs, and CDO losses, were so
large that they threatened the ability of the CDS issuers to meet their obligations
(counterparty risk). Then, impairment tests kicked in and the banks had to write
