Investment banks assist public and private corporations in raising funds in the capital markets, as well as in providing strategic advisory services for M&As and other types of financial transactions. They also act as intermediaries in trading for clients. Investment banks differ from commercial banks, which take deposits and make commercial and retail loans. In recent years, however, the difference between them has blurred, especially as commercial banks are now offering more investment banking services. In the U.S., the Glass-Steagall Act, created in the wake of the Stock Market Crash of 1929, prohibited banks from simultaneously accepting deposits and underwriting securities; it was repealed by the Gramm-Leach-Bliley Act in 1998. Investment banks may also differ from brokerages, which in general assist in the purchase and sale of stocks, bonds, and mutual funds.
