Structure of Investment Banks plays an important role in defining the way in which an investment bank works. These investment banks play an important role in the economy by connecting companies, governments, and investors with capital markets. Investment banks, unlike retail banks, do not deal with personal banking services. Rather, they are investment-focused banks with large-scale financial activities such as raising funds, advising on mergers, and more.
In 2025, investment banks will be more advanced and technology-driven than before. Their structure ensures smooth operations, accountability, and efficiency. By exploring the structure of investment banks, we explain what an investment bank is. In addition, we also provide an overview of the framework, describe key departments, and other important aspects.
