Deutsche Bank has hired Mark Sibley from J.P. Morgan Securities as an addition to its London-based integrated credit-trading desk. He is currently on "gardening leave" and will join the firm next month. Sibley, who will be based in London, will report to Antonio di Flumeri, head of European non-emerging markets credit derivatives trading, a firm spokesman said. At J.P. Morgan, Sibley was a telecom, media and technology dollar/euro flow trader, and will be filling a similar post at Deutsche Bank. A spokesman at J.P. Morgan declined to comment.
