UBS chief executive Sergio Ermotti said that the Swiss bank could shrink its office space, as up to a third of its employees potentially continue to work from home in the wake of the coronavirus crisis.

The bank will be “reassessing the way we work going forward” Ermotti said during a call accompanying UBS’s second quarter results, after more than 90,000 staff have been working remotely for months as Covid-19 forced countries to lockdown.
