A rogue employee at a unit of Mitsubishi Corporation used unauthorized trades to bet on oil markets, disguised them to look like "hedge transactions" with customers, then lost millions when the market went south.
The employee, at Petro-Diamond Singapore, a Mitsubishi Corporation unit, had been building the positions since January, Mitsubish said on Friday, confirming "that it expects to book a loss of approximately $320 million from its trade of crude oil derivatives."
The falling crude oil price since July translated into "large losses," it said. The company discovered the trades in August and fired the employee and filed a police complaint this week.
