Some people are keeping their London-based gigs (for now) and some people are not. JPMorgan Chase, the biggest U.S. lender by assets, will eliminate 20 investment-banking jobs in London as market conditions weaken, according to a person with knowledge of the cuts. The staff cuts aren’t related to the $2 billion loss at the New York-based company’s chief investment office in London, said the person, who asked for anonymity because the investment bank reductions haven’t been made public.
