“Only four years later, in May 2012, it emerged that JP Morgan trader Bruno Iksil (known as the London Whale) had carried out aggressive trading activities in the credit default swaps market which led to market losses of $7bn.”
Iksil was a skilled trader, who carried out the trades his boss ordered him to carry out. He told his boss, Achilles Macris, that the trades wouldn’t work out, and suggested they cut their losses.
Iksil is not on the list of rogue traders.
