Moody's Multi-Billion Computer Bug

Publish date:

As it turns out, our robot overlords are destroying human civilization.

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, a 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.

Simple question: If a computer bug is Moody's excuse, why did these things get triple A ratings from Standard & Poor's also?
