Bank Nifty: The World's Most Actively Traded Index by Options Volume
Bank Nifty — officially the Nifty Bank Index — tracks the performance of the 12 most liquid and large-cap banking stocks listed on NSE. It was launched in September 2003 and has become the most actively traded index derivatives contract in the world by options contract count. On a single day, Bank Nifty options regularly see notional turnover exceeding ₹80,000–₹1,20,000 crore — making it the heartbeat of Indian derivatives trading.
For F&O traders, Bank Nifty is the primary vehicle. Its high volatility (typically 20–30% higher than Nifty 50), twice-weekly expiry (every Wednesday for weekly, monthly on last Thursday), and strong trending behaviour make it ideal for both directional option buying and premium collection strategies.

Bank Nifty Expiry Strategy: Wednesday Weekly
Bank Nifty has weekly options expiring every Wednesday (introduced in 2019) in addition to monthly contracts. The Wednesday expiry creates unique trading dynamics. In the final hour before expiry (2:00 PM to 3:30 PM IST), gamma becomes extremely high — small price moves cause massive option premium changes. This is the "gamma squeeze" environment favoured by experienced option traders but extremely dangerous for beginners.
