Domestic Institutional Investors (DIIs) are financial institutions based in India that invest in domestic financial markets, including stocks and bonds. These institutions include mutual funds, insurance companies, pension funds, banks, and Non-Banking Financial Companies (NBFCs). The funds they manage are typically sourced from Indian individuals, policyholders, or entities, distinguishing them from foreign investors.
DIIs operate on a pooled investment model, where capital collected from multiple investors is allocated across various asset classes. This structure allows for centralised, professionally managed investment decisions, guided by regulatory frameworks and internal policies.
