UBS Group AG[nb 1] is a Swiss multinational investment bank and financial services company founded and based in Switzerland. Co-headquartered in the cities of Zürich and Basel, it maintains a presence in all major financial centers as the largest Swiss banking institution in the world. UBS client services are known for their strict bank–client confidentiality and culture of banking secrecy.[nb 2] The bank's large positions in the Americas, EMEA, and Asia Pacific markets make it a global systemically important financial institution.
UBS was founded in 1862 as the Bank in Winterthur alongside the advent of the Swiss banking industry. During the 1890s, the Swiss Bank Corporation (SBC) was founded, forming a private banking syndicate that expanded aided by Switzerland's international neutrality. The Bank of Winterthur merged with Toggenburger Bank in 1912 to form the Union Bank of Switzerland (UBS) and grew rapidly after the Banking Law of 1934 codified Swiss banking secrecy. Following decades of market competition between the SBC and UBS, the two merged in 1998 to create a single company known solely as "UBS".[nb 3] During the early 2000s, the commensurate rise of UBS and Credit Suisse established a legally-sanctioned oligopoly on Swiss private market activity. After UBS managed heavy losses during the 2008 financial crisis with an asset relief recovery program, it was hit with the 2011 rogue trader scandal resulting in a US$2 billion trading loss. In 2012 the bank reoriented itself around wealth management and limited its sell side operations.
