Losses accumulated: $1.3 billion
Perhaps the most famous rogue trader of all time. In 1995, Leeson led England's 233-year old Barings bank into bankruptcy with failed bets on Nikkei futures. The $1.3 billion of liabilities he had run up was more than the entire capital and reserves of the bank. Eventually arrested in Frankfurt, Germany, Nick spent a few fraught months trying to escape extradition to Singapore. He failed and in December 1995 a court in Singapore sentenced him to six-and- a-half years in prison. In 1999, his story was then turned into a film, Rogue Trader, starring Ewan McGregor.
