Goldman Sachs is putting more muscle into its Swiss business: the U.S. investment banking giant is ramping up on staff in Geneva. The move follows an upgrade in Zurich earlier this year.

The New York-based bank will bolster staff in Geneva to roughly 20 bankers, from five currently, it said in a statement on Friday. Goldman Sachs is taking an office move within the Swiss city as an opportunity to include asset and wealth management in its offering, beside its flagship investment banking and securities services.

The move comes after Goldman Sachs reopened Geneva last year after shuttering the office in 2016. The bank, under Swiss head Stefan Bollinger, recently bedded down in Zurich, upgrading the office into a branch regulated by Swiss overseer Finma, from a representative office previously.
