The Nifty 50 index slipped nearly 220 points from its day’s high on Tuesday, as traders adjusted to a historic change in India’s derivatives market. For over two decades, Thursdays were etched in stone as the weekly F&O expiry day. Starting September 2025, the NSE shifted the expiry to Tuesday, forcing a complete recalibration of trading strategies.
This marks the first Tuesday expiry for Nifty contracts, with the transition taking effect after the August 28 session. The move means Mondays will now serve as the new “expiry eve,” increasing weekend risks for traders and altering market positioning dynamics.
Adding to the pressure, India VIX spiked 3%, signaling higher volatility across the market. The Nifty Bank index also tumbled more than 500 points from its day’s high, amplifying the selling pressure.
After 25 years of Thursday expiries, today’s shift represents the beginning of a new era in India’s derivatives landscape, with volatility likely to remain elevated as traders adapt to the new schedule.
