JPMorgan in London has hired Raymond de Kuiper, previously at Morgan Stanley, as a v.p. and derivatives marketer covering Northern Europe. He reports to Ian Wilson, co-head of Northern Europe derivatives marketing. De Kuiper is an addition to the group which has just lost Michael Poppel, a structured credit marketer in the financial institutions derivatives marketing group. Poppel could not be reached and it could not be determined if he has taken a new position. Sarah Oppler, spokeswoman in London, said Poppel will be replaced.
