The bankruptcy of New York-based futures brokerage MF Global created an uproar with the shocking disclosure that as much as $1.2 billion in customer accounts was missing. MF Global, led by former New Jersey governor and Goldman Sachs chairman Jon Corzine, declared bankruptcy after making a disastrous bet on European sovereign debt. Chicago-based CME Group Inc., which guarantees the trading on its exchanges, has come under intense criticism, because it is supposed to protect investors.
