Marcel Rohner became the youngest chief executive of a European bank by five years when he took the reins at UBS in 2007. Less than two year’s later he is stepping down from the Swiss bank to be replaced by a man 20 years his senior.

Rohner began his career at the Swiss Bank Corporation in 1992 after graduating from the University of Zurich with a PhD in economics. His first job at the bank was as an assistant to its head of derivatives, and he later worked in market risk control, rising to group head of risk in 1999, following SBC's merger with UBS in 1998.
