SEBI’s CAS rollback: Brokers welcome VWAP return, but market veterans flag risks
BusinessLine 1 hr ago·16 Oct 2026, 5:01 pm
The Securities and Exchange Board of India (SEBI) has rolled back its controversial Closing Auction Settlement (CAS) framework, a move that has been met with a mix of relief and caution. The regulator has decided to revert to the previous Volatility-Wave Average Price (VWAP) mechanism for settlement, effectively cancelling the new rules that were introduced with the aim of reducing volatility during the closing auction. This decision comes after the market regulator received significant feedback from brokers and exchanges regarding the practical difficulties and unintended consequences of the new framework.
For investors, this development signals a return to a more familiar settlement process, potentially reducing the chances of sudden price swings during the final trading hour. However, the abrupt policy reversal has raised questions about the regulatory process and market stability. Market veterans are concerned that the frequent changes in settlement rules can create uncertainty for market participants and may not fully address the underlying issues of market integrity that the new framework was designed to tackle.
Investors should watch for SEBI's next steps and any potential consultation papers regarding market structure. The focus now shifts to how the regulator plans to address the concerns raised by market participants while ensuring a fair and orderly market. The rollback provides a temporary pause, but the debate over the best way to manage closing auction volatility is likely to continue.
