The Securities Contracts (Regulation) Act of 1956 was enacted by the Indian Parliament to prevent undesirable transactions in securities markets and promote orderly development. It defines key terms, deals with the recognition and supervision of stock exchanges, and regulates contracts in listed securities. The act was introduced due to a history of stock market crashes and manipulations in India dating back to the 1860s that highlighted the need for regulation to protect investors and support market stability. It has since been amended several times, including in 2012, to further strengthen regulation and incorporate changes.
