The roles of Bill Winters, Fawzi Kyriakos-Saad and John Corrie, all senior European officials at JPMorgan, will reportedly be changed in a move to globalize business lines and center them in New York. Speculation is that Kyriakos-Saad will leave the firm (as opposed to being reassigned) but this, and the intentions of Winters and Corrie, could not be confirmed. Spokeswoman Sarah Oppler declined comment. Winters, based in London, co-headed the investment bank with Steve Black, based in New York. Their joint role is tipped to be merged under one person but it is not clear if this will be Black. The responsibilities of Corrie and Kyriakos-Saad are expected to be folded under New York colleagues.
