My Manhattan Project
How I helped build the bomb that blew up Wall Street.

I have been called the devil by strangers and “the Facilitator” by friends. It’s not uncommon for people, when I tell them what I used to do, to ask if I feel guilty. I do, somewhat, and it nags at me. When I put it out of mind, it inevitably resurfaces, like a shipwreck at low tide. It’s been eight years since I compiled a program, but the last one lived on, becoming the industry standard that seeded itself into every investment bank in the world.

I wrote the software that turned mortgages into bonds.

Because of the news, you probably know more about this than you ever wanted to. The packaging of heterogeneous home mortgages into uniform securities that can be accurately priced and exchanged has been singled out by many critics as one of the root causes of the mess we’re in. I don’t completely disagree. But in my view, and of course I’m inescapably biased, there’s nothing inherently flawed about securitization. Done correctly and conservatively, it increases the efficiency with which banks can loan money and tailor risks to the needs of investors. Once upon a time, this seemed like a very good idea, and it might well again, provided banks don’t resume writing mortgages to people who can’t afford them. Here’s one thing that’s definitely true: The software proved to be more sophisticated than the people who used it, and that has caused the whole world a lot of problems.

The first collateralized mortgage obligation, or CMO, was created in 1983 by First Boston and Salomon Brothers, but it would be years before computer technology advanced sufficiently to allow the practice to become widespread. Massive databases were required to track every mortgage in the country. You needed models to create the intricate network of bonds based on the homeowners’ payments, models to predict prepayment rates, and models to predict defaults. You needed the Internet to sail these bonds back and forth across the world, massaging their content to fit an investor’s needs at a moment’s notice. Add to all this the complacency, greed, entitlement, and callous stupidity that characterized banks in post-2001 America, and you have a recipe for disaster.

1. The financial equivalent of taking the plans for the Golden Gate Bridge and

building it out of spaghetti!

2. Actually a more apt analogy than you know...

both involve creating exponentially growing chain reactions.
