Credit Crunch... Blame the programmers!

Interesting item from FT.Com.

Quote:
Moody’s awarded incorrect triple A ratings to billions of dollars worth of a type of complex debt product due to a bug in its computer models, an Financial Times investigation has discovered.

Internal Moody’s documents seen by the FT show that some senior staff within the credit agency knew early in 2007 that products rated the previous year had received top-notch triple A ratings and that, after a computer coding error was corrected, their ratings should have been up to four notches lower.

News of the coding error comes as ratings agencies are under pressure from regulators and governments, who see failings in the rating of complex structured debt as an integral part of the financial crisis. While coding errors do occur there is no record of one being so significant.

Moody’s said it was “conducting a thorough review” of the rating of the constant proportion debt obligations - derivative instruments conceived at the height of the credit bubble that appeared to promise investors very high returns with little risk. Moody’s is also reviewing what disclosure of the error was made.

The products were designed for institutional investors. In the recent credit market turmoil, those who still hold the products will have suffered some paper losses while others who have bailed out have lost up to 60 per cent of their investment.

On discovering the error early in 2007, Moody’s corrected the coding glitch and instituted methodology changes. One document seen by the FT says “the impact of our code issue after those improvements in the model is then reduced”. The products remained triple A until January this year when, amid general market declines, they were downgraded several notches.
Behooves me to think that the math / financial geeks could not have spotted what seemed like obviously dodgy products and are busy hiding behind the "these were too exotic for ordinary humans to rate" nonsense.

Not a slip ... was the nickname they ended up getting.
