NSE Cash Market Sees Record ₹39,718 Cr Turnover in Closing Auction

The National Stock Exchange of India (NSE) recorded an unprecedented turnover of ₹39,718 crore during its Closing Auction Session (CAS) on Monday, August 31. This historic figure represented 22% of the exchange's total cash market turnover for the day.

The significant trading volume occurred as the MSCI August 2026 Index Review took effect, marking the first substantial index rebalancing event since the CAS was implemented earlier in August. This mechanism, introduced for stocks with available derivative contracts, aggregates buy and sell orders to discover a single closing price.

Over 98,000 unique investors participated, with NSE commanding a 99.9% market share in the CAS. The exchange noted that the strong participation validates the CAS as an effective tool for index funds and passive investors to execute portfolio realignments during rebalancing periods.

This development brings Indian capital markets closer to global best practices for price discovery. The record turnover during this index review event highlights the CAS's crucial role in managing significant market activities.
