NSE options hit a one-year low as closing auction, expiry shift chill India's IPO-bound exchange
Premium turnover on India's NSE slid to about ₹670 billion a day — its lowest since the bourse moved expiry day to Tuesday a year ago — and cash-equity volumes fell to their weakest since November. The culprit is the new closing-auction mechanism plus tighter trading rules, which have thinned the expiry-day strategies that once drove the tape. That timing stings: options fees generated roughly 60% of NSE's operating revenue last fiscal year, just as it lines up India's biggest-ever IPO.
