Trading BANKNIFTY options (now monthly expiry)

Heads up: BANKNIFTY no longer has weekly options. After NSE's 2024 rationalisation of index derivatives, each exchange keeps weekly expiries on a single benchmark index only — on NSE that is NIFTY (Tuesday). BANKNIFTY now trades monthly expiries only (last Tuesday of the month). If you arrived here looking for "BANKNIFTY weekly options", that product has been withdrawn — the strategies below apply to the monthly contract.

BANKNIFTY is more volatile than NIFTY, with a wider strike interval (100 vs 50) and larger point swings. That higher volatility means richer option premiums — and bigger risk on a trending day. Premium-selling strategies need wider strikes and tighter risk control on BANKNIFTY than on NIFTY.

What changes vs NIFTY

Practical differences when you move a strategy from NIFTY to BANKNIFTY:

• Monthly expiry only — no weeklies, so positions carry more days of theta and gap risk
• Wider strike grid (100 points) — gaps and hedges are placed further apart
• Higher implied volatility — more premium, but faster, larger moves
• A trend day can blow through short strikes quickly — adjustments matter more

Strategies that suit it

Iron Condors and Iron Flies work on BANKNIFTY monthlies with appropriately wider strikes. Many traders prefer the defined-risk Iron Condor here precisely because BANKNIFTY can move hard over a month — the bought wings cap what a gap day can cost. Because the monthly contract decays more slowly than a weekly, give the position room and manage adjustments rather than expecting fast theta.
