UBS already has a bank in Frankfurt with the necessary licenses to serve wealth management and investment banking and Ermotti indicated it is now a question how UBS shares the jobs around Europe.

"We are looking between a couple of countries like Spain or Holland still maybe having, on a branch basis, people operating from those locations under the license of our Frankfurt-based bank," Ermotti told reporters.

The bank's "worst case scenario" had involved the shift of around 1,000 jobs out of London but Ermotti said this possibility had been reduced in recent months.
