Financial journalist David Enrich tells the true story of British trader Tom Hayes and his part in “the spider network” that fueled the infamous Libor scandal. The saga offers an unflattering exposé of the world of financial market traders and investment bankers. Enrich provides a visceral taste of what it’s like to work in finance, painting such a vivid picture of the incentives and the environment that you’ll almost feel sorry for the “carnivorous,” bonus-chasing, seemingly amoral bankers. Enrich shows that the trading culture abetted Hayes, who’s now in prison, and saved his bank bosses and associates – none of whom served a day in jail. Even if you don’t come to this tale already dubious about the trading activities of large investment banks, you will be plenty skeptical by its end.

Libor’s importance expanded during the 1990s with the growth of trading in derivatives. Derivative contracts must include a standard by which to represent the underlying cost of borrowing. Nonfinancial companies use derivatives as tools to hedge against the impact of changing interest rates on their businesses. But derivatives are also perfect...
