These changes aim to address current market inefficiencies and reduce volatility. The proposal also includes adjustments to the timing of the continuous trading session (CTS) and derivatives trading. These measures are part of SEBI's broader effort to improve the functioning of the auction process and ensure fairer market conditions for all participants. ## Options for Settlement Prices The first option involves using the volume-weighted average price (VWAP) of the last 30 minutes of trading for settlement. The second option proposes using the closing price of the underlying security. Both methods aim to provide a more accurate reflection of market conditions at expiry. SEBI believes these changes will reduce manipulation and ensure smoother settlement processes. Market participants are currently evaluating the potential impact of each option on their trading strategies. ## Changes to Trading Session Timing SEBI's proposal includes modifying the timing of the continuous trading session (CTS) to better align with global markets. The new timings are expected to reduce overlaps with other major markets, minimizing volatility. Additionally, the changes aim to provide traders with more time to adjust their positions before settlement. These adjustments are particularly significant for institutional investors who trade across multiple time zones. The proposed timings are still under review and may be adjusted based on feedback. ## Impact on Derivatives Trading The proposed changes are expected to have a significant impact on derivatives trading strategies. Traders will need to adapt to new settlement price mechanisms and revised trading hours. The adjustments may also affect liquidity, especially during the final hours of trading. Market makers and arbitrageurs are likely to be the most affected by these changes. SEBI has emphasized that the new rules are designed to enhance market integrity and protect retail investors. ## Additional Measures for Auction Functioning Beyond settlement prices and trading hours, SEBI is introducing additional measures to improve auction functioning. These include enhanced transparency requirements and stricter reporting standards. The regulator aims to reduce information asymmetry and ensure a level playing field. The new rules will also require more detailed disclosures from market participants. These measures are part of SEBI's ongoing efforts to modernize India's financial markets. ## Potential Benefits for Market Participants The proposed changes are expected to benefit both retail and institutional investors. Reduced volatility and more accurate settlement prices will lead to fairer outcomes. Enhanced transparency and stricter reporting will improve market confidence. The alignment with global trading hours may attract more foreign investment. Overall, SEBI's reforms aim to create a more robust and efficient derivatives market in India. ## Challenges and Criticisms Some market participants have raised concerns about the practicality of the new settlement price options. Critics argue that the VWAP method may be difficult to implement consistently. Others worry that the changes to trading hours could disrupt existing strategies. SEBI has acknowledged these concerns and is open to feedback. The regulator plans to conduct extensive consultations before finalizing the rules. ## Conclusion and Next Steps SEBI's proposed changes represent a significant step forward for India's derivatives market. The reforms aim to enhance efficiency, reduce volatility, and improve fairness. Market participants have until the end of the year to provide feedback on the proposals. SEBI will then finalize the rules, which are expected to take effect in early 2027. These changes underscore SEBI's commitment to creating a world-class financial market ecosystem in India. ## Sources covering this story - https://economictimes.indiatimes.com/markets/stocks/news/explained-what-sebis-proposed-cas-changes-mean-for-expiry-day-trading-and-settlement/articleshow/134122773.cms — --- _Summary written by Brifing from the original reporting.
