Bruno Iksil, the former JPMorgan Chase & Co. trader whose bets caused more than $6.2 billion in losses last year, is now central to any U.S. charges against his former colleagues.

Iksil, the Frenchman who became known as the London Whale because of his trading book’s size, has been cooperating with the Federal Bureau of Investigation and the Manhattan U.S. Attorney’s Office for months in their probe of the New York-based bank’s biggest trading debacle ever, said three people with direct knowledge with the matter. Iksil won’t face charges as long as he cooperates and testifies, the people said.
