Investment banking

An investment bank is a financial institution that assists individuals, corporations, and governments in raising financial capital by underwriting or acting as the client’s agent in the issuance of securities (or both). An investment bank may also assist companies involved in mergers and acquisitions (M&A) and provide ancillary services such as market making, trading of derivatives and equity securities, and FICC services (fixed income instruments, currencies, and commodities). Unlike commercial banks and retail banks, investment banks do not take deposits. From 1933 (Glass’Steagall Act) until 1999 (Gramm’Leach’Bliley Act), the United States maintained a separation between investment banking and commercial banks. Other industrialized countries, including G8 countries, have historically not maintained such a separation. As part of the Dodd’Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank Act of 2010), Volcker Rule asserts full institutional separation of investment banking services from commercial banking. The two main lines of business in investment banking are called the sell side and the buy side. The “sell side” involves trading securities for cash or for other securities (e.g. facilitating transactions, market-making), or the promotion of securities (e.g. underwriting, research, etc.). The “buy side” involves the provision of advice to institutions concerned with buying investment services. Private equity funds, mutual funds, life insurance companies, unit trusts, and hedge funds are the most common types of buy side entities. An investment bank can also be split into private and public functions with an information barrier which separates the two to prevent information from crossing. The private areas of the bank deal with private insider information that may not be publicly disclosed, while the public areas such as stock analysis deal with public information. An advisor who provides investment banking services in the United States must be a licensed broker-dealer and subject to U.S. Securities and Exchange Commission (SEC) and Financial Industry Regulatory Authority (FINRA) regulation.
