Citi is one of the largest banks in the world, tracing its lineage to the City Bank of New York founded in 1812 and taking its modern shape through the 1998 merger that created Citigroup. Its most distinctive asset is a cross-border payments and treasury network unmatched by any competitor, moving trillions of dollars a day for multinational corporations, governments and other banks across roughly ninety countries. Alongside that institutional franchise it runs markets and investment banking, wealth management and a United States personal bank, and has spent recent years simplifying itself by exiting consumer operations across Asia, Europe and Latin America.
