The following list catalogues the largest, most profitable, and otherwise notable investment banks. This list of investment banks notes full-service banks, financial conglomerates, independent investment banks, private placement firms and notable acquired, merged, or bankrupt investment banks. As an industry it is broken up into the Bulge Bracket (upper tier), Middle Market (mid-level businesses), and boutique market (specialized businesses).[1] [2]
The following are the largest full-service global investment banks; full-service investment banks usually provide both advisory and financing banking services, as well as sales, market making, and research on a broad array of financial products, including equities, credit, rates, currency, commodities, and their derivatives. The largest investment banks are noted with the following:[3] [4]
JPMorgan Chase Goldman Sachs BofA Securities Morgan Stanley Citigroup

Such combinations were common in Europe but illegal in the United States prior to the passage of the Gramm-Leach-Bliley Act of 1999.
