Triple-A Failure

I’m currently working my way through Roger Lowenstein’s 5,000-word Triple-A Failure in a preview of the Sunday New York Times. I highly recommend it. Here’s the opening:

In 1996, Thomas Friedman, the New York Times columnist, remarked on “The NewsHour With Jim Lehrer” that there were two superpowers in the world — the United States and Moody’s bond-rating service — and it was sometimes unclear which was more powerful. Moody’s was then a private company that rated corporate bonds, but it was, already, spreading its wings into the exotic business of rating securities backed by pools of residential mortgages.
Obscure and dry-seeming as it was, this business offered a certain magic. The magic consisted of turning risky mortgages into investments that would be suitable for investors who would know nothing about the underlying loans. To get why this is impressive, you have to think about all that determines whether a mortgage is safe. Who owns the property? What is his or her income? Bundle hundreds of mortgages into a single security and the questions multiply; no investor could begin to answer them. But suppose the security had a rating. If it were rated triple-A by a firm like Moody’s, then the investor could forget about the underlying mortgages. He wouldn’t need to know what properties were in the pool, only that the pool was triple-A — it was just as safe, in theory, as other triple-A securities.
Over the last decade, Moody’s and its two principal competitors, Standard & Poor’s and Fitch, played this game to perfection — putting what amounted to gold seals on mortgage securities that investors swept up with increasing élan. For the rating agencies, this business was extremely lucrative. Their profits surged, Moody’s in particular: it went public, saw its stock increase sixfold and its earnings grow by 900 percent.
By providing the mortgage industry with an entree to Wall Street, the agencies also transformed what had been among the sleepiest corners of finance. No longer did mortgage banks have to wait 10 or 20 or 30 years to get their money back from homeowners. Now they sold their loans into securitized pools and — their capital thus replenished — wrote new loans at a much quicker pace.
Mortgage volume surged; in 2006, it topped $2.5 trillion. Also, many more mortgages were issued to risky subprime borrowers. Almost all of those subprime loans ended up in securitized pools; indeed, the reason banks were willing to issue so many risky loans is that they could fob them off on Wall Street.
