Campelli will manage the bank's transformation processes and its workforce, tasks previously shared by several managers. He has been the bank's global head of wealth management but starts his new role with immediate effect.

"Given the size of the task there needs to be one Management Board member devoting all his energies to this comprehensive transformation," Supervisory Board Chairman Paul Achleitner said in a statement.

The costs of the bank's turnaround plan, announced in July, are estimated at $7.4 billion.
