UBS is a merger of Swiss bank (Swiss Bank Corporation) and Zurich-based United Swiss Bank (Union Bank of Switzerland). The safest and most trustworthy Swiss bank that is often mentioned is represented by UBS. UBS is currently the largest financial holding group in Europe, headquartered in Zurich, Switzerland, with more than 50,000 employees in more than 50 countries and regions around the world, serving more than 4.5 million customers. The renowned financial services company, the world's largest asset management company, the largest investment guarantee bank, is also a leading private service, serving more than four million individuals and businesses. UBS is headquartered on the streets of Bahnhof Zurich and the building is not conspicuous. Legend has it that the basement of UBS headquarters, the safe deposit box, is located just below Banhof Street, so many people are curious.
