Kaspar Villiger has asked interim chief executive Sergio Ermotti to quicken a scaling back of the investment bank so details can be revealed at the bank’s investor day on 17 November.
“Revamping the bank will probably take the next two or three years until it’s all completed,” Villiger said. He also highlighted Ermotti’s experience and Swiss nationality as advantages should he be named chief executive.
Former Bundesbank boss Axel Weber, who is due to join the board next year and become chairman in 2013, has already provided advice in the search for a permanent chief executive.
The bank is looking at candidates inside and outside UBS and expects to make an appointment within six months.
Yesterday Ermotti condemned the “totally unacceptable” risk exposure that led to UBS’ $2.3bn (£1.5bn) loss and said an internal investigation into Kweku Adoboli’s alleged fraud will be completed within 10 to 14 days, although it is not certain that the findings will be made public.
Ermotti also pledged to show “humility and energy” in the job and said he would review the bank’s risk controls.
“We are aware that we are facing turbulent times externally and this latest incident is only adding much more necessity for us to react. But let’s not forget that UBS is one of the best capitalised banks worldwide,” he said.
Ermotti has been groomed as a possible successor to Gruebel since he joined UBS as head of Europe, Middle East and Africa in April from UniCredit, but some analysts have questioned whether he has sufficient gravitas for the top job.
Villiger said he had no doubts about the future of investment bank head Carsten Kengeter, whose fate had also hung in the balance, but declined to comment on whether he could still be a candidate for chief executive.
