UBS is naming a Swiss banker who recently returned from a stint in Asia to spearhead its business with multinational corporate clients and strategic transactions.

Roger Bieri returned from Zurich from Singapore six months ago and just racked up a promotion: UBS is naming the Swiss banker head of multinationals and strategic transactions within UBS' corporate and institutional clients, effective October 1. He will deputize for Andy Kollegger, head of the UBS division's products and services.

A 24-year veteran of the bank, Bieri replaces Simone Westerfeld, who was promoted within UBS' Swiss business, as finews.com reported. Previously, he was head of corporate clients in Asia for six years and a member of UBS' top management in the region. He returned to Switzerland in March as head of corporate and institutional clients in international services.
