When A Computer Glitch Mucks Up Bond Ratings

from the what-do-you-do dept

Interesting story in the financial world, as the Financial Times reported that Moody's, the big name in the bond rating business, may have incorrectly rated certain bonds as Aaa, its highest rating -- given only to a class of bonds that will almost never default. Apparently, the incorrect ratings were due to a computer glitch (always a convenient scapegoat). However, more troublesome is the Financial Times' claim that it has seen documents suggesting that Moody's execs were aware of the error last year and didn't do much to change the incorrect ratings. This is troublesome, as it would be a big hit to Moody's reputation -- which is its biggest asset. Of course, when you rely on a single source (or a single algorithm) to rate bonds, this sort of thing is bound to happen eventually -- and extracting yourself from the resulting mess is always going to be tricky. It makes you wonder if there aren't better ways to rate bonds, that don't have a single point of failure.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    Because companies actually care enough to fix those bugs quickly.

    S&P also give those bonds AAA ratings, and they have no bugs

    Apparently

    Now this is some fantastic spin. There was no "glitch". There was no "bug". The computers were not at fault. The problem was an incredibly bad, arguably incompetent, algorithm design which made some very bad assumptions about the relevance of the data it was using.

    Conflicts of interest

    "The problem was an incredibly bad, arguably incompetent, algorithm design which made some very bad assumptions about the relevance of the data it was using."

    The fact that other ratings agencies came up with similar bogus ratings casts serious doubt on the "computer error" spin. "Computer error" is the business equivalent of "The cat ate my homework".

    It seems more likely that the problem arose because the ratings agencies were paid large sums of money to come up with the "right" ratings.

    bonds and Aaa rate

    Hi:
    We Americans are being runed by criminal actions and our government allows it... IRS, FED, and other private agencies have taken over America. I'm ashamed to be American and so powerless to change things. Y'know with all the rubbish going on it saddens my heart.
