Wall Street’s 9 Worst Bets Ever: From Nick Leeson to JPMorgan
7. Jon Corzine, MF Global
After seeing his bid for another term as governor of New Jersey thwarted by Chris Christie, Jon Corzine landed on both feet, assuming leadership of the futures and bond dealer MF Global. At Corzine’s direction, the firm bet $6 billion on sovereign bonds issued by European countries.

Meanwhile Corzine remains dogged by suspicions over whether the brokerage illegally dipped into customer accounts to meet capital requirements once the firm began losing money.
