"Chase" is the brand name used for the consumer and commercial banking subsidiary of the multinational financial corporation known as JPMorgan Chase & Co. While many customers simply refer to the institution as "Chase," the formal corporate entity has been known as JPMorgan Chase since the historic merger between the Chase Manhattan Corporation and J.P. Morgan & Co. in December 2000. This merger created one of the largest banking institutions in history, combining the extensive retail branch network of Chase with the deep investment banking and wealth management expertise of J.P. Morgan. Consequently, while the retail branch signs and digital banking portals display the "Chase" logo and branding to maintain consumer-facing familiarity, the legal and financial entity is officially JPMorgan Chase & Co., which continues to operate under that name in global financial markets, on stock exchanges, and in official corporate filings.
