Qualified Institutional Buyers (QIB), are institutional investors who are considered to have the knowledge and resources to invest in the financial markets. This group includes mutual funds, insurance companies, pension funds, and other major financial institutions. They are regulated under SEBI’s guidelines in India and are subject to specific regulations in different countries to ensure fair and orderly markets. QIB are vital in the financial economy as they stabilize the market, affect prices, access private deals, and show confidence in new investments.
