My rating: 5 of 5 stars
I've done a fair amount of reading about the Panic of 2008, and Gillian Tett's "Fools Gold" explains the exotic investment instruments at the heart of the panic better than any other work I've read. A group of derivatives traders at J.P. Morgan created commoditized credit default swaps in the early 1990s as a way to move risk off the company's books, freeing up capital for lending and investment that otherwise would need to be held in reserve. Morgan made payments to AIG, which assumed the risk that Morgan's assets would go into default. Derivatives traders at other firms began assembling securities backed by subprime mortgages, trying to put together instruments that would be just risky enough to obtain returns but safe enough to obtain AAA ratings. They then paid AIG to assume the risk of the mortgages underlying those securities going bad. However, many institutions kept what they thought were the least risky of these mortgages on their own books, as they could not obtain much in the way of returns on the securities that they would back. The whole thing was unregulated by government, and the ratings agencies were easily bamboozled into turning poo into gold (as it turned out). As the cruddy mortgages went bad, AIG began to take on water. When the less risky mortgages went bad, the financial institutions themselves sank.

Interestingly, J.P. Morgan did not get into the business of mortgage backed securities. Morgan's mathematicians could not put together a risk model with the kind of integrity to which they were accustomed. First, they had no data on what could happen if real estate values ever declined. Second, they had no long-term data on default rates for the kinds of subprime mortgages that proliferated in the early and mid 2000s. Moreover, Morgan/Chase chairman Jamie Dimon pushed the concept of a "fortress balance sheet" containing rock-solid assets on which the bank could rely if things went to hell. Dimon pushed Morgan's derivatives traders to investigate getting into the business of mortgage backed securities a couple of times, but, consistent with the notion of a "fortress balance sheet," he accepted the traders' reasons for staying away from that business.

The book contains a brief account of the events leading to the Lehman Brothers bankruptcy that turned a situation into a panic, and concludes with Tett's cultural analysis of U.S. and U.K. investment houses.
