What is Investment Banking?

As I already told you about one of the functions of Investment banking, however, it is not the primary function.

Investment Banking is a segment or a branch of banking that helps individuals, governments, or organizations to raise funds and provide financial consultancy services to them. In a way, they act as intermediaries between security issuers and investors.

Apart from this, some of their other functions are:-

  • underwriting debt and equity securities for all types of corporates.

  • They help to facilitate mergers and acquisitions, reorganization and broker trades for institutions and private investors,.

However, here are some of the functions of an investment banker:

  • Underwriting – Private companies issue shares for the public to raise funds. Investment bankers help them to raise capital and underwrite the debt. They act as a bridge between investors and companies. This function serves the primary market.

Just to avoid confusion

Please do not get confused about an investment bank for any other commercial bank. Investment banks do not take deposits from customers as commercial banks do. The customers of investment banks are generally the one who want funds (organizations or government) and the one who wants to invest. They help the government in raising funds from the public through bonds, as the government does not have the expertise and knowledge about raising funds as well as investment banks do.

Example of Investment Banking

Let’s finish this with an example to understand better how investment banks work.

Think of a company ABC, that wants to buy another company XYZ. Now, ABC does not know about the worth of XYZ company and the long-term benefits in terms of revenue, cost, etc. ABC Co. will reach out to investment bankers for their expertise and help. Now, investment banks will go through all the processes, like determining the value of the company, negotiating on behalf of ABC Co., settling a deal by helping the company to prepare necessary documents, and, lastly, advising the company on the right time for the deal.

Here, as you know, the investment bank is working on the buy side. However, some investment banks must be working on the sell-side of the XYZ company. Investment banks earn from the commission of the deal, the bigger the deal and so would be the commission.


Today the majority of countries are mixed economies, and as a result, their government and private enterprises depend on investment banks for their services when they need funds. And as mentioned earlier, investment banks act as a bridge between potential investors and potential sellers of stocks, or in short they ‘add liquidity to the market’.
