Credit Suisse is also primary dealer and Forex counterparty of the FED.

Credit Suisse was founded in 1856 to fund the development of Switzerland’s rail system. It issued loans that helped create Switzerland’s electrical grid and the European rail system. In the 1900s, it began shifting to retail banking in response to the elevation of the middle class and competition from fellow Swiss banks UBS and Julius Bär. Credit Suisse partnered with First Boston in 1978 before buying a controlling share of the bank in 1988. From 1990 to 2000, the company purchased institutions such as Winterthur Group, Swiss Volksbank, Swiss American Securities Inc. (SASI), and Bank Leu. The biggest institutional shareholders of Credit Suisse include the Qatar Investment Authority and BlackRock (about 5% each), the US mutual fund providers Harris Associates (the largest shareholder as of August 2022, with 10.1%) and Dodge & Cox, the central bank of Norway and the Saudi Arabian Olayan Group.[8][9]

The company was one of the least affected banks during the global financial crisis, but afterwards began shrinking its investment business, executing layoffs and cutting costs. The bank was at the center of multiple international investigations for tax avoidance which culminated in a guilty plea and the forfeiture of US$2.6 billion in fines from 2008 to 2012.[10][11] In 2021, Credit Suisse had assets under management (AuM) of over CHF 1.6 trillion.[12]
