The National Securities Clearing Corporation Ltd. (NSCCL), a wholly owned subsidiary of NSE, was incorporated in August 1995. It was set up to bring and sustain confidence in clearing and settlement of securities; to promote and maintain, short and consistent settlement cycles; to provide counter-party risk guarantee, and to operate a tight risk containment system. NSCCL commenced clearing operations in April 1996.

NSCCL carries out the clearing and settlement of the trades executed in the Equities and Derivatives segments and operates Subsidiary General Ledger (SGL) for settlement of trades in government securities. It assumes the counter-party risk of each member and guarantees financial settlement. It also undertakes settlement of transactions on other stock exchanges like, the Over the Counter Exchange of India.

NSCCL has successfully brought about an up-gradation of the clearing and settlement procedures and has brought Indian financial markets in line with international markets.
