Securities and Exchange Board of India (SEBI)

SEBI is the regulatory authority in India, responsible for overseeing and regulating the securities market in India. It ensures that all market participants, including investors, brokers, and companies, operate within a fair and transparent framework.

SEBI sets rules, monitors market activities, and takes corrective actions against malpractices such as insider trading, fraud, and market manipulation.

Its regulatory authority extends to various segments of the financial market, including mutual funds, portfolio managers, investment advisors, and other intermediaries.

History of SEBI

The Securities and Exchange Board of India (SEBI) was initially established in 1988 as a non-statutory body to regulate the stock market. However, it lacked sufficient powers to enforce regulations efficiently.

Later, in 1992, the Indian Parliament passed the SEBI Act, granting it statutory status and full authority to frame rules and take corrective measures when needed.

With the SEBI Act 1992, SEBI was granted autonomous powers, allowing it to regulate and supervise the share market in a comprehensive manner.

After receiving the regulatory powers, it has introduced various regulations and guidelines to promote good governance, prevent manipulation, and enhance investors' confidence.
