Founding Story

Modern UBS was created in 1998 when Union Bank of Switzerland and Swiss Bank Corporation merged, joining two lineages that date back to the nineteenth century (Bank in Winterthur in 1862 and Basler Bankverein in 1872). The merger aimed to give a Swiss bank the scale to compete globally in wealth management, asset management and investment banking. In 2000 UBS bought US brokerage PaineWebber, laying the base for its large American wealth business.
