Investment Bank
An investment bank plays a crucial role in the financial ecosystem by assisting corporations and other entities in securing financing through the issuance of securities. Unlike traditional banks, investment banks do not accept deposits; instead, they focus on complex financial transactions, including mergers and acquisitions. Their services are typically divided into two main categories: the sell side, which helps companies sell securities to raise capital, and the buy side, which provides investment advice and resource allocation strategies to clients.
Historically, investment banks initially focused on underwriting securities but have since evolved to offer a broader range of financial services, such as market research and portfolio management. Regulatory frameworks like the Glass-Steagall Act separated commercial and investment banking activities for much of the 20th century to protect consumers, but this changed in 1999 with the repeal of the act. This shift allowed banks to offer both types of services again, though it raised concerns about financial stability, leading to reforms like the Dodd-Frank Act.
Investment banks are structured into three operational categories: the front office, which generates revenue through client interaction; the middle office, which manages the bank's financial health; and the back office, which ensures accurate transaction processing. A key aspect of their advisory role involves risk analysis, helping clients navigate different investment strategies according to their risk tolerance and investment goals. However, the potential for conflicts of interest and instances of insider trading present ethical challenges within the industry, contributing to its complex reputation.

Investment Bank
Investment banks serve the important function of assisting other entities in obtaining financing for their operations through the issuance of ownership shares in the project or company. An investment bank differs from a traditional bank in that it does not accept deposits in the way that savings and loan banks do. Instead, they offer assistance to corporations engaging in complex transactions such as mergers and acquisitions. Investment banking activities are usually characterized as belonging to one of two categories: the buy side or the sell side. The sell side consists of the investment bank providing assistance with selling securities in other companies in order to help those companies raise capital. The buy side involves the provision of assistance and advice by the investment bank to other entities about how they should invest their resources and what investment instruments they should use.
Brief History
Investment banking has taken on a variety of forms throughout its history. Initially, its activities consisted primarily of underwriting the issuance of securities. Later, this work gradually expanded to include a full range of financial services, such as market research and the management of investments through the supervision of client portfolios. For much of the twentieth century, banks in the United States were prohibited from offering both investment banking services and traditional banking services, under the 1933 Glass-Steagall Act. Glass-Steagall was passed into law as a response to the irresponsible banking practices that culminated in the 1929 market crash; banks had essentially taken funds from their commercial activities—deposits from private investors, often representing the life savings of individuals—and used it to finance their investment banking operations, placing investors’ money at great risk without their knowledge or permission. Glass-Steagall required that commercial banking and investment banking be conducted by separate institutions, in order to remove the temptation for banks to repeat this behavior.
In 1999, the Glass-Steagall Act was repealed, once again allowing banks to offer "universal" services. Some have argued that this relaxation of the rules contributed to the economic crisis of 2008, when a number of large banks overleveraged themselves in the subprime mortgage market and required government financial assistance in order to return to solvency. The repeal was coupled with the Gramm-Leach-Bliley Act of 1999, which eliminated the separation between investment and commercial banks and influenced most major banks to combine investment and commercial banking operations. In 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act was passed to restore some of the restrictions on banks seeking to conduct both commercial and investment services. Notably, Dodd-Frank includes the Volcker Rule (named for Paul Volcker, Chairman of the Federal Reserve Bank), which restricts a practice known as proprietary trading, in which a commercial bank uses customer deposits for its own investment banking trades. Such trades are permissible if the customer asks the bank to perform them, but not if the bank seeks to make the trades on its own initiative and without the customer’s approval.
In 2018, as a means of deregulating and overriding parts of both the Dodd-Frank Act and the Volcker Rule, the Economic Growth, Regulatory Relief, and Consumer Protection Act raised the asset threshold from $50 billion to $250 billion, meaning smaller and mid-sized banks faced significantly less stringent regulations. It also eliminated the Volcker Rule for small banks with less than $10 billion in assets. Critics argued that such decisions could open the market to greater systemic risks.
Overview
An investment bank divides its activities into three different categories. These categories are referred to as front office, back office, and middle office. Back office operations are often outsourced to other companies, but remain crucial for an investment bank’s business, because they involve processing the trades customers have requested and making sure that each trade has been successfully completed. In other words, back office tasks consist of making sure that the bank has handled other people’s transactions correctly. Middle office functions, on the other hand, are focused on managing the bank’s own business. Middle office managers are tasked with making sure that the bank’s own financial position is strong and that its risk portfolio is within acceptable parameters. Investment banks are in business to generate a profit for themselves, largely through transaction fees, so the middle office makes sure that expenses are kept in check and revenues are directed to appropriate channels. The front office is the segment of the investment bank that exists to generate revenue, and it does this by interfacing directly with customers. Investment banks generate revenue by providing their clients with services in the form of conducting market research on clients’ behalf; buying and selling securities at clients’ behest; and providing clients with information and advice about how to structure their investments and liabilities, as well as how to engage in complex transactions and stock offerings.
A key component of investment banking involves risk analysis and risk management. As part of an investment bank’s advisory role with clients, it seeks to provide clients with a realistic assessment of the level of risk and potential for reward inherent in a particular investment strategy. This involves a thorough understanding of the client’s situation and investment philosophy. Some clients are well-financed and thus are likely to be more comfortable with an aggressive investment portfolio, and are willing to accept higher levels of risk in exchange for larger or more rapid returns on their investments. Other clients are comfortable with a much more conservative approach, whether this is due to their financial limitations or simply to a desire for greater predictability in the performance of their portfolio. These clients will prefer lower levels of risk, with the understanding that returns on their investments are likely to be lower and to take longer to manifest.
An area of particular concern related to investment banking is that it is a field with great potential for conflicts of interest to arise. Investment banks deal with huge sums of money, with deals in the billions of dollars not being uncommon. Investment banks are also privy to confidential and extremely valuable information, especially when they are in the position of assisting a private firm with preparing its initial public offering of stock. These two factors combine to make insider trading a temptation for those privy to such information. Insider trading involves the use of someone inside a company or investment bank using confidential information in order to make investments that anticipate the public release of that information. Making use of information not available to the investing public to seize a financial advantage is illegal. Past incidents of insider trading, as well as the large sums of money investment banks sometimes pay their executives, have given investment banking a mixed reputation in some circles.
