This is the authors coming of age story, set in the world of investment banking in the 1980s. As a growth and wisdom book, its pretty good, but its really a non-fiction version of Tom Wolfs Bonfire of the Vanities. Of course what makes it interesting is that Michael Lewis came of age by successfully trading bonds for Solomon Brothers.
Among other aspects of the firm, LP describes Solomons Mortgage Bonds department, its influence over the savings and loans, and the effect of Fed Chairman Paul Volkers 1981 decision to let interest rates float. Lewis does a brilliant job of explaining how this lead to S&Ls selling their mortgages in order to fund investments in higher yield securities.
Heres the catch: Liars Poker appeared before the S&L debacle but it laid out all the signs needed to predict the disaster to come.
Much of the hand wringing over S&Ls in the early 90s could maybe have been avoided if the warnings given in this book had been acted upon. To be fair, the warnings are clear but they are implicit. Lewis never actually projects the current state of the S&L industry into the future, even if he does mention that the basic problem with mortgages (short term funding of long term loans) is not solved.
Good read.
