As reported today by Bloomberg<\/a>:<\/p>\n

The IMF, which is charged with promoting global economic stability and lends to financially distressed nations, blamed the crisis on “benign economic and financial conditions” which “weakened incentives to conduct due diligence on borrowers and counterparties.”The fund also said the methodology of credit-rating companies, some of which gave high ratings to subprime mortgage securities that have plummeted in value, needs to be examined. The complexity of many of these securities may have made it difficult for investors to assess their worth based on the assigned ratings.<\/p>\n

“In the case of complex structured credit products, investors need to look behind the ratings,” the report said.<\/p>\n

Regulators and investors will have to work together to strengthen financial markets to prevent a recurrence, and develop ways to improve the spread of accurate and timely information to help markets assess risk, the report said.<\/p><\/blockquote>\n

Parts of this report are available at the IMF site<\/a>. In Chapter 1<\/a> they urge:<\/p>\n

The need for a differentiated scale of credit ratings has
\nagain been made apparent.<\/strong>
\nThe fallout in the mortgage market has drawn attention to the role of credit ratings agencies in structured credit markets. Less sophisticated investors, who were content to delegate the risk assessment of their positions to the credit ratings agencies, were negatively surprised by the intensity of downgrades. Previous GFSRs have pointed out that structured credit products are likely to suffer more severe, multiple-notch downgrades relative to the typically smoother downgrade paths of corporate bonds (IMF, 2006). The experience of the past year has underscored the need for further efforts to inform investors of these risks, but better still would be the introduction by ratings agencies of a more differentiated scale for structured credit products. For example, a special rating scale for structured credits could be introduced to highlight to investors that they should expect a higher speed of migration between ratings than on a traditional corporate bond.<\/p><\/blockquote>\n

The section (page 37 of the PDF) ends with some sound advice for institutional investors; sadly, it does not advocate that institutional investors who bought CDOs without understanding them seek retraining as ditch diggers. The closest they get to advocating this urgently needed market reform is elsewhere in the document:<\/p>\n

Finally, credit ratings evaluate only default risk, and not market or liquidity risks, and this seems to have been underappreciated by many investors.<\/p><\/blockquote>\n

Which isn’t really very close, is it? Ah, well, perhaps someday.<\/p>\n
