CAS review: Sebi announces last 30-minute VWAP method for settlement
Business Standard 1 hr ago·15 Oct 2026, 4:18 pm
Sebi has updated its rules for the closing auction session, introducing a new method for determining settlement prices in derivatives. Instead of the previous method, the regulator will now use the Volume Weighted Average Price (VWAP) calculated over the last 30 minutes of trading. This change is set to be implemented from December 7, 2026, marking a significant shift in how market participants will conclude their daily trades.
This modification is designed to provide a more accurate reflection of market sentiment during the final minutes of trading. By using the VWAP, the settlement price aims to be more representative of the actual trading activity, potentially reducing volatility and manipulation risks. For retail investors, this means a more stable closing process, though it does not alter the fundamental trading hours for equities.
Investors should monitor how the market adapts to this new framework when it is fully rolled out. While the change is a few years away, staying informed about regulatory shifts helps in understanding the evolving market infrastructure. Keep an eye on any further clarifications from Sebi to ensure your trading strategies align with the new settlement rules.
