CAS crash: Nifty plunges 462 points in less than 30 seconds. Will Sebi’s review break trend?
Economic Times 1 hr ago·15 Sept 2026, 11:13 am
The Indian stock market experienced a sudden and sharp drop in the Nifty 50 index during the closing auction session on Tuesday. The benchmark index fell by approximately 2% in a matter of seconds before prices stabilized and recovered. This volatility occurred while the market was in the final minutes of trading, raising questions about the stability of the new Continuous Auction System (CAS).
This event is significant because it highlights a potential technical glitch or operational risk within the new settlement framework. For investors, the primary concern is the reliability of price discovery during the crucial closing window. The crash underscores the need for a robust system that can handle high volumes without significant volatility.
Investors should closely monitor the minutes from the upcoming board meeting of the Securities and Exchange Board of India (Sebi). Any announcements regarding a review of the CAS rules or technical fixes will be critical. Market participants will be watching to see if the regulator intervenes to restore confidence in the new trading mechanism.
