What Do Investment Banks Do?

Investment banks play a crucial role in financial markets, offering a range of financial services to help corporations and governments achieve financing, mergers and acquisitions, listings, and other objectives. Through professional financial analysis, strategic planning, and market operations, investment banks provide access points and solutions to capital markets for their clients.

One of the core businesses of investment banks is corporate finance services. They assist companies in issuing bonds, stocks, and other financial instruments to raise funds from capital markets to meet their expansion, operational, or research and development needs. Additionally, investment banks provide merger and acquisition advisory services, helping companies achieve scale expansion, strategic transformation, or resource integration.

Beyond corporate finance and M&A consulting, investment banks are actively involved in stock market trading and underwriting. They offer initial public offering (IPO) services to listed companies, facilitating capital raising and enhancing market influence. Simultaneously, investment banks are significant market makers, providing liquidity for stock trading and maintaining the stable operation of the market.

The role of investment banks in financial markets cannot be overstated. Through professional financial services and market operations, they promote the prosperity and development of capital markets, providing powerful support to corporations and governments.
