assistant whales

A fourth London-based JPMorgan Chase trader is under scrutiny in the investigation by U.S. authorities into the bank’s nearly $6 billion trading loss, according to sources familiar with the situation. Julien Grout, a trader who joined JPMorgan Chase in 2009, is drawing attention because he worked in the bank’s Chief Investment Office and reported to Bruno Iksil, the French credit trader who is a central figure in the federal probe, said the two sources. U.S. authorities are trying to determine whether traders in the bank’s London office, including Iksil, took steps to try and hide some of the losses the bank was incurring on a series of complex derivatives trades. In the trading community in London, Iksil became known as the London Whale because of the large positions he and his colleagues were taking on. Grout, who is also French, is still working for JPMorgan, according to a bank spokeswoman. [Reuters]
