What Is Investment Banking?

If you’re like most people, you probably figure investment banking got its start in a towering office skyscraper in New York City. But the real story of the origin of investment banking is far less metropolitan, yet arguably even more interesting. Investment banking traces its roots to the age of kings and queens. Many of the most commonly used financial instruments trace their origins to centuries ago when bankers navigated the edicts of rulers and, believe it or not, religious leaders.

But for now, just know that investment banking is, at its very core, pretty straightforward. Investment banking is a method of controlling the flow of money. The goal of investment banking is channeling cash from investors looking for returns into the hands of entrepreneurs and business builders who are long on ideas, but short on bucks.

Investment bankers raise money from investors, by selling securities, and then transfer that money to people who need cash to start businesses, build buildings, run cities, or bring other costly projects to reality.

There are many aspects of investment banking that muddy this fundamental purpose. But in the end, investment bankers simply find opportunities to unlock the value of companies or ideas, create businesses, or route money from being idle to having a productive purpose.

The role investment banking plays

Investment bankers get involved in the very early stages of funding a new project or endeavor. Investment bankers are typically contacted by people, companies, or governments who need cash to start businesses, expand factories, and build schools or bridges. Representatives from the investment banking operation then find investors or organizations like pension plans, mutual funds, and private investors who have more cash than they know what to do with (a nice problem to have) and who want a return for the use of their funds. Investment banks also offer advice regarding what investment securities should be bought or the ones an investor may want to buy.

One of the trickiest parts of understanding investment banking is that it’s typically a menu of financial services. Some investment banking operations may offer some services, but not others.

The services offered by investment banks typically fall into one of a few buckets. One of the best ways to understand investment banks is to examine all the functions that some of the biggest investment banks perform. For example, Morgan Stanley, one of the world’s largest investment banks, has its hands in several key business areas, including the following:

• Capital raising: This part of the investment banking function helps companies and organizations generate money from investors. This is typically done by selling shares of stock or debt.
• Financial advisory: In this role, the investment banking operation is hired to help a company or government make decisions on managing their financial resources. Advice may pertain to whether to buy another company or sell off part of the business. A common business decision tackled by this type of investment banking is whether to acquire another company or divest of a current product line. This is called mergers and acquisitions (M&A) advisory.
• Corporate lending: Investment banks typically help companies and other large borrowers sell securities to raise money. But large investment banks are also frequently involved in extending loans to their customers, often short-term loans (called bridge loans) to tide a company over while another transaction is in the works.
• Sales and trading: Investment bankers are a creative and innovative lot, in the business of constructing financial instruments to be bought and sold. It’s natural for investment bankers to also buy and sell stocks and other financial instruments either on the behalf of their clients or using their own money.
• Brokerage services: Some investment banking operations include brokerage services where they may hold clients’ assets or help them conduct trades.
• Research: Investment banks not only help large institutions sell securities to investors, but also assist investors looking to buy securities. Many investment banks run research units that issue research reports and advise investors on whether they should buy a particular investment.

The terms investments and securities are pretty much interchangeable.

• Investments: Investment banks typically serve the role of a middleman, sitting between the entities that need money and those that have it. But periodically, units of investment banking operations may invest their own money in promising companies or projects. This type of investment, often made in companies that don’t have investments that the public can buy, is called private equity.

Investment banking operations at one firm may be engaged in some of the preceding activities, but not all. There’s no rule that demands investment banking operations must perform all the services described here. As investment firms grow, though, they often add functions so they’re more valuable to their clients and can serve as a common source for a variety of services.

How investment banking differs from traditional banking

The critical part of the investment banking process is in the way cash is funneled from the people who have it to the people who need it. After all, traditional banks do essentially the same thing investment banks do — get cash from people who have excess amounts into the hands of those who have productive uses for it.

Traditional banks take deposits from savers with excess cash and lend the money out to borrowers. The main types of traditional banks are commercial banks (which deal primarily with businesses) and retail banks (which deal mostly with individuals).

The difference between traditional banks and investment banks, though, is the way money is transferred between the people and institutions that need it and the ones who have it. Instead of collecting deposits from savers, as traditional banks do, investment bankers usually rely on selling financial instruments (such as stocks and bonds), in a process called underwriting. By selling financial instruments to investors, the investment bankers raise the money that’s provided to the people, companies, and governments that have productive uses for it.

Because banks accept deposits from Main Street savers, those deposits are protected by the Federal Deposit Insurance Corporation (FDIC), which guarantees bank deposits. To protect itself, the FDIC along with the federal government puts very strict rules on banks to make sure they’re not being reckless.

On the other hand, investment banks, at least until the financial crisis of 2007 (see the appendix), were free to take bigger chances with other people’s money. Investment banks could be more creative in inventing new financial tools, which sometimes don’t work out so well. The idea is that clients of investment banks are more sophisticated and know the risks better than the average person with a bank account.

The meaning of the term investment bank got even more unclear after the financial crisis that erupted in 2007. Due to a severe shock to the bond market, many of the dedicated investment banks went out of business, including venerable old-line firms such as Lehman Brothers and Bear Stearns, or were bought by banks. Many of today’s largest investment banks are now units of banks or technically considered commercial or retail banks, although they still perform investment banking operations. Meanwhile, these banks will often say they perform investment banking functions. The term investment bank is somewhat of a misnomer, because the major financial institutions are now technically considered banks.

Now that you see that the chief role of investment banks is selling securities, the next question is: What types of securities do they sell? The primary forms of financial instruments sold by investment banks include the following:

• Equity: If you’ve ever bought stock in a company, be it an individual firm like Microsoft or an index fund that invests in companies in the Standard & Poor’s (S&P) 500, you’ve been on the investor end of an equity deal. Investment bankers help companies raise money by selling ownership stakes, or equity, in the company to outside investors. After the securities are sold by the investment bank, the owners are free to buy or sell them on the stock market. Equity is first sold as part of an equity offering called an initial public offering (IPO).
• Debt capital: Some investors have no interest in owning a piece of the company, but they’re more than willing to lend money to it, for a price. That’s the role of debt capital. Investment banks help companies borrow money by issuing bonds, or IOUs, that are sold to investors. The company must pay the prearranged rate of interest, but it doesn’t give up any ownership of the company. If a company falls onto hard times, though, the owners of the debt have a higher claim to assets than do the equity owners if a liquidation of the company is necessary.
• Hybrid securities: Most of what investment banks sell can be classified as either debt or equity. But some securities take on traits of both, or are an interesting spin on both. One example is preferred shares, which give investors an income stream that’s higher than what’s paid on the regular equity. But preferred shares don’t come with as high a claim to assets as bonds, and this income stream can be suspended by the company if it chooses.

The services investment banks provide

Investment banks do much more than just raise capital by selling investments. Although selling securities to raise money is arguably the primary function of investment banks, they also serve several other roles. All the functions of investment banks typically fall into one of two primary categories: selling or buying.

• The sell side: Investment banks are best known for the part of their business that sells securities, or the sell side. This function of the investment bank is responsible for finding investors to buy the securities being sold, which raises the money needed by businesses and governments to grow and prosper.
• The buy side: Investment banks may also take the role of advising the large investors who are interested in buying financial instruments. Serving in its role on the buy side, the investment bank can offer suggestions to large institutional investors like mutual funds, pension plans, or endowments on which securities may be appropriate for it to buy in order to meet return targets.

The dual role played by investment banking operations, serving both buyers and sellers of securities, raises constant worries of double dealing and conflicts of interest. Some people rightly question whether it’s possible for the same investment bank that makes money selling shares of an IPO, for instance, to give honest and unbiased investment advice to investors trying to decide whether they should buy or sell. The question of conflicts of interest in investment banking operations has become paramount since the financial crisis began in 2007.

How investment banks are organized

Investment banks may seem like financial behemoths that have their hands in just about any matter that involves large sums of money. And to a large degree, that’s true. Investment banks are usually involved in some fashion when it comes to financing major projects, conducting trading in financial instruments, or developing new ways to generate capital.

With that said, nearly all major investment banks divide their operations into several key areas, including the front office, middle office, and back office. When you talk to someone about investment banking, or even listen to the heads of investment banks talk, they’ll often refer to these three common parts of a traditional investment bank:

• The front office: The front office is exactly what it sounds like. It’s not only the part of the investment bank that sells investments, but also the part that courts companies looking to do deals. Traditionally, companies that are looking to find a fast way to turbo-charge growth may think about buying another company (say, a rival with similar customers or complementary technology).

From the front office, investment banks help usher along the M&A process by pairing up buyers and sellers. The front office is also the part of the investment bank that conducts trading (frenetic buying and selling of securities to take advantage of any mispricings — even if the holding period is for only a few seconds).

Investment banks used to do some trading using complicated mathematical formulas and using the firm’s money (not the clients’ money). This type of trading is often called proprietary trading. Many investment banks used to operate a business where they bought and sold securities themselves. Proprietary trading was quite profitable for investment banks. But most types of so-called prop trading by investment banks were abolished in mid-2015 by the Volcker Rule. The rule is named after former Federal Reserve Board Chairman Paul Volcker. Volcker said risky trading put large financial institutions at risk. Such trading was blamed in part for the financial crisis of 2008. Investment banks will continue to wind down this part of their businesses into the early 2020s.

Another part of the front office is the part of the business involved in conducting research on companies. The front office often employs sell-side analysts, whose job it is to closely monitor companies and industries and produce reports used by large investors trying to decide whether to buy or sell particular securities.

• The middle office: The middle office of an investment bank is generally out of the limelight. It’s the part of the bank with the job of cooking up new types of securities that can be sold to investors. Some innovations in investment banking are useful, but others can wind up putting investors and the markets in general in an unfavorable light. Some of the infamous financial instruments cooked up in the middle office of investment banks that came back to haunt the system include auction-rate securities and credit default swaps.

Auction-rate securities are debt instruments that promise investors higher rates of return than are available in savings accounts. Instead of selling debt at a prearranged interest rate, the investment bank would conduct auctions, and the rate would be set by a bidding process. That’s great as long as there are willing buyers and sellers. But the auction-rate market relied on auctions, many of which weren’t successful during the financial crisis that erupted in 2007. Many investors holding the securities found they couldn’t sell them because the market had dried up, causing a huge headache for the investors and investment banks. Credit default swaps are tools that allow lenders to sell the risk that borrowers won’t be able to meet their obligations. Credit default swaps operate as a form of unregulated insurance policies. These instruments got so complicated, though, that they exacerbated the financial interdependencies between giant financial firms, worsening the financial crisis that erupted between 2007 and 2009.

• The back office: The back office is the part of the investment bank that is far from the glamour of the front office. It’s primarily made up of the systems and procedures that allow investment bankers to gather the data they need to do their jobs well. The back office, for instance, maintains the computer systems used by investment bankers to gauge interest in certain securities and provides traders the ability to make short-term bets on market movements. The parts of investment banking considered more operational in nature tend to fall into the back office.

Investment banking operations are rarely identical between firms. Some banks and investment banks are engaged in some front-office areas, while others steer clear of them completely. There are also some peripheral areas of business some banks and investment banks include as part of their services that don’t fall in one of the traditional “offices.” One example of a service that is often grouped in investment banking is investment management. In an investment management unit, investment professionals are paid to invest money on behalf of individual clients or institutions.

The current lay of the investment banking land

After the tumultuous changes in the investment banking business following the financial crisis of 2007 through 2009, the entire landscape changed. Following the banking crisis, investment banks needed capital. Some of the most storied investment banks, unable to raise money, merged with other banks or became commercial banks themselves. Suddenly, the financial system was comprised of behemoth banks that have the deposit-taking abilities of banks but also engage in investment banking. The result is the formation of several mega-institutions that many people fear are “too big to fail,” including the ones shown in the table. Source: S&P Global Market Intelligence

Types of investment banking operations

Insiders in the investment banking business use all sorts of terms, some decidedly derogatory, to classify the players in the business. Some classifications that investment banks fall into include the following:

• Bulge bracket: Bulge bracket investment firms aren’t the ones that ate too many slices of cheesecake. Instead, bulge bracket is a commonly used slang term to describe the biggest of the big investment banking operations. The bulge bracket firms are the behemoths, like the ones in the table. They have their hands in most areas of investment banking.
• Boutique: Boutique investment firms are smaller investment banks and traditional banks that choose to focus on one or a select few areas of the business. Some firms, for instance, focus on selling securities for smaller companies.
• Regional: Regional firms typically focus on a particular part of the country. Whereas the bulge bracket firms continually try to grow and take market share from rivals, there seems to be plenty of room for smaller players like these. Some regional firms also often concentrate on a particular type of investment banking service, be it trading services or underwriting of securities.

How investment banks get paid

As you can imagine, although investment banking plays an important role in funding economic progress, there’s also lots of money to be made. Investment bankers can’t afford those fancy suits if they’re not getting paid.

Investment bankers perform services for customers and collect money in a number of ways, include the following:

• Commissions: Investment banks sometimes collect fees in exchange for conducting a financial transaction between a buyer and seller. One of the more common forms of commissions is often collected in the brokerage operations by some traditional banks and investment banks. For instance, Merrill Lynch, the brokerage and investment banking unit of Bank of America, charges commissions when purchasing stock for its customers. But that’s just a small example.
• Underwriting fees: A lucrative area of investment banking generates fees for selling securities in the primary market (the collection of buyers’ and sellers’ interest in trading brand-new securities). When a company sells stock to the public for the first time, for instance, the investment banker who handles the deal, called the underwriter, collects a fee.
• Trading income: Investment banks usually handle other people’s money. But many investment banking operations also include a trading division. This unit attempts to take advantage of temporarily mispriced financial instruments. This high-risk proprietary trading is designed to generate profits for the firm.
• Asset management fees: Some investment banks help their clients make decisions on how to invest their money. Investment banks generate asset management fees when they help clients decide which securities they should buy or sell.
• Advisory fees: Companies often look to their investment banks for advice, especially in the cases of M&A deals. And in these cases, the investment bankers are brought in to provide in-depth, numerical analysis of a proposed deal. The companies pay substantial fees for this high-level assistance.
