JPMorgan Chase trader Bruno Iksil, known as the London Whale because his bets this year were so large, has been a leviathan of a risk-taker since at least 2010, a person with knowledge of the matter told people at Bloomberg.
Iksil’s value-at-risk, a measure of how much a trader might lose in one day, was typically $30 million to $40 million even before this year’s buildup, said the person, who wasn’t authorized to discuss the trades. Sometimes the figure, known as VaR, could surpass $60 million, the person said. That’s about as high as the level for the firm’s entire investment bank, which employs 26,000 people.
Investigators are examining how long senior executives knew about Iksil’s swelling bets at the chief investment office before losses approached $2 billion…. His bosses may not have understood the complexity of his trades, said a person, who asked for anonymity because the information hasn’t been released publicly…..
