India’s newly launched closing auction session recorded its lowest traded quantity during its first week of operation [2].
The lack of participation suggests a struggle to integrate the new mechanism into daily trading habits. If liquidity remains thin, the session may fail to provide the stable price discovery it was designed to achieve for the National Stock Exchange.
The closing auction session, known as CAS, lasts for 15 minutes [1]. During this period, traded volumes were lower than those seen during comparable continuous-trading intervals throughout the day [1]. This trend emerged during the first week following the launch of the session [2].
Market data indicates that domestic traders and retail investors largely stayed away from the auction [1]. This absence of local participation left the session with thin liquidity, a condition that can lead to higher volatility and wider spreads.
Some foreign market makers have responded to the low activity by requesting market-making support [1]. These traders said such support is necessary to boost volumes and attract more participants to the closing window [1].
The National Stock Exchange introduced the CAS to align with global trading standards. However, the initial response from the domestic market has been muted. While foreign entities are open to the system, they require structural incentives to ensure the session remains viable [1], [2].

The poor debut of the closing auction session highlights a gap between regulatory intent and trader behavior in India. While the 15-minute window is intended to reduce volatility at the market close, the current lack of retail and domestic interest creates a liquidity vacuum. The reliance on foreign market makers to stabilize the session suggests that the exchange may need to introduce new incentives or educational initiatives to encourage local participation.
