Sebi to tweak CAS, change method for derivative trade
Times of India 1 hr ago·3 Sept 2026, 11:18 pm
The Securities and Exchange Board of India (Sebi) is set to review the current methodology for calculating settlement prices in the derivatives market. This comes after the market regulator released a consultation paper proposing changes to the Collateral Allocation System (CAS). The goal is to refine how prices are determined, which could impact the valuation of securities held as margin.
For investors, this move is significant because the CAS determines the amount of cash or securities a trader must deposit to open or maintain a position. A change in the calculation method could alter the margin requirements for various stocks, potentially affecting liquidity and trading costs. It also signals Sebi's focus on strengthening market stability and reducing systemic risk.
Investors should monitor the final circular once it is issued. Traders will need to adjust their risk management strategies based on the new rules. Brokers and clearing houses will also be key players in implementing these changes, so keeping an eye on their announcements will be important for staying ahead of the curve.
