RBI funding curbs, CAS take a toll on proprietary volumes | Stock Market News
From July, banks asked proprietary traders for full collateral, and from August Sebi's closing auction session (CAS) changed how closing prices are set. Prop traders' share of NSE equity options fell to a 22-month low of 47.3% in August, and total volumes dropped on both exchanges. If you trade options, expect thinner liquidity near close. Sebi is reviewing the method and wants public comments.
Key Statutory Highlights
- Proprietary traders' combined share of index and stock options on the NSE fell to 47.3% in August, its lowest level in 22 months.
- NSE's average daily premium turnover in equity options dropped 15.7% to ₹42,332 crore in August, while BSE's turnover fell 26% to ₹18,672.32 crore.
- Sebi issued a consultation paper seeking public comments on proposed changes to the settlement methodology for index derivatives.
Actionable Advice for Taxpayers / Founders:If you trade equity or index options, review how the closing auction session affects your strategy in the final 15 minutes of trading, where liquidity has thinned. If these changes matter to your business, you may consider sending your views on Sebi's consultation paper on index derivatives settlement.
