What Is an Investment Bank?

Investment banks are financial institutions that help corporations, governments, and large entities raise capital by issuing securities such as stocks and bonds. They also provide advisory services for mergers and acquisitions, restructurings, and other high-value financial transactions. Unlike commercial banks that serve individuals with deposits, loans, and savings accounts, investment banks primarily serve corporations, governments, and institutional investors.

The bank acts as an intermediary between businesses seeking capital and investors providing funds. They help companies raise money, manage risk, and execute strategic financial deals. In essence, they are the architects of the financial markets, designing and facilitating transactions that keep capital flowing.

Investment banks operate in both domestic and international markets, often playing a critical role in the functioning of global financial systems. Some of the most prominent investment banks include Goldman Sachs, J.P. Morgan, and Morgan Stanley.
