JPMorgan Chase, one of the world's largest banks by market value, was created in 2000 by the merger of J.P. Morgan and Chase Manhattan Bank.
The merger combined J.P. Morgan, a major investment bank, with Chase Manhattan, a large commercial bank. The resulting company was named J.P. Morgan Chase and Co. Bank One later merged with the company in 2004, and JPMorgan Chase acquired Washington Mutual's banking operations in 2008.
The chain of mergers makes the bank's history easy to confuse. Citibank and Bank of America are separate institutions, while Chase Manhattan is a predecessor of today's Chase consumer-banking brand. The company now operates across consumer banking, commercial banking, investment banking, asset management, and payments.
