These are the same guys who rated subprime mortgage backed bonds AAA. How the rating agencies still have any credibility is completely incomprehensible to me. I hope someone in the press has the wherewithal to make this point.
While the {S&P, Moodys, Fitch} sub-prime department obviously got completely ahead of itself modelling-wise, the corporate and sovereign departments have a lot of credibility : partly because they haven't been trying to assign values to 'a whole new way of doing things (this time it's different, etc)'.
