One of the major problems with these credit rating agencies is that
they made money by charging private issuers for a rating. This created a conflict
of interest as they were being paid by those who were judging them and were
themselves competing with other rating agencies for profits. Many critics claim
that this conflict of interest led agencies to award these AAA ratings to these
complex securities which they did not properly understand.
These same rating agencies have failed before and will fail again.
Thailand maintained an investment grade rating until 5 months after the Asian
financial crisis, whilst Enron, the largest bankruptcy in US history at the
time, had an investment grade rating until just days before it went bankrupt.
In May 2008, Moody’s acknowledged that it had given AAA-ratings to
billions of dollars of structured finance products due to a bug in one of its ratings
models (Jones, Tett, and Davies, 2008). In March 2007, First Pacific Advisors discovered
that Fitch used a model that assumed constantly appreciating home prices,
ignoring the possibility that they could fall. (Coval, J.D et al, 2008)
They have not learned their lesson and they have a lot to answer for
when it comes to the subprime mortgage crisis. Bill Gross gave his view on the
credit ratings agencies which I believe sums there role up appropriately.
“AAA? You were wooed Mr. Moody’s and Mr. Poor’s by the makeup,
those six-inch hooker heels, and a ‘tramp stamp.’ Many of these good-looking
girls are not high-class assets worth 100 cents on the dollar.”
