Investment banking

Investment banks help companies and governments and their agencies to raise money by issuing and selling securities in the primary market. They assist public and private corporations in raising funds in the capital markets (both equity and debt), as well as in providing strategic advisory services for mergers, acquisitions and other types of financial transactions.

Investment banks 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 lines between the two types of structures have blurred, especially as commercial banks have offered more investment banking services. In the US, the Glass-Steagall Act, initially created in the wake of the Stock Market Crash of 1929, prohibited banks from both accepting deposits and underwriting securities; Glass-Steagall was repealed by the Gramm-Leach-Bliley Act in 1999. Investment banks may also differ from brokerages, which in general assist in the purchase and sale of stocks, bonds, and mutual funds. However some firms operate as both brokerages and investment banks; this includes some of the best known financial services firms in the world.

In the strictest definitioncitation needed], investment banking is the raising of funds, both in debt and equity, and the division handling this in an investment bank is often called the "Investment Banking Division" (IBD). However, only a few small firms provide only this service. Almost all investment banks are heavily involved in providing additional financial services for clients, such as the trading of derivatives, fixed income, foreign exchange, commodity, and equity securities. It is therefore acceptable to refer to both the "Investment Banking Division" and other 'front office' divisions such as "Fixed Income" as part of "investment banking," and any employee involved in either side as an "investment banker." Furthermore, one who engages in these activities in-house at a non-investment bank is also considered an investment banker.

More commonly used today to characterize what was traditionally termed "investment banking" is "sell side." This is trading securities for cash or securities (i.e., facilitating transactions, market-making), or the promotion of securities (i.e. underwriting, research, etc.).

The "buy side" constitutes the pension funds, mutual funds, hedge funds, and the investing public who consume the products and services of the sell-side in order to maximize their return on investment. Many firms have both buy and sell side components.
