Nasdaq's Hans-Ole Jochumsen will take on a new role as vice-chairman of the transatlantic exchange group from the start of 2017, a move that will see the Dane return to Europe on a full-time basis ahead of what he described as a "big year" for the region's bourses.

Jochumsen joined Nasdaq with its 2008 acquisition of Nordic exchange group OMX, and has been appointed to roles of increasing strategic importance ever since.
