BANK NIFTY — A Monthly-Only Product Now
BANK NIFTY lost its weekly option in 2024. What monthly-only means for its decay profile, and how to trade a high-beta index without a weekly contract.
BANK NIFTY was, for years, the trader's favourite weekly: a high-beta index with cheap, fast-decaying weekly options that delivered big intraday swings. SEBI's one-weekly-per-exchange rule ended that in November 2024. BANK NIFTY is now a monthly-only product, expiring the last Tuesday of the month.
That single change reshapes how you trade it. This chapter covers what monthly-only does to the contract's behaviour and how to approach a high-beta index when there's no weekly to lean on.
What 'monthly-only' changes
Slower theta, higher premium. A monthly option has weeks of life, so its time decay per day is far gentler than a weekly's, and its absolute premium is much larger. The cheap, rapidly-decaying lottery tickets that defined BANK NIFTY weekly trading simply don't exist anymore.
Decay concentrates near the end. Theta on a monthly accelerates in the final week or two before the last Tuesday. So the 'expiry-week' dynamics — IV crush, pinning, decay — still happen, but they're compressed into the back end of the month rather than recurring every week.
How to trade a high-beta index without a weekly
Use the monthly's expiry week for the decay and pinning setups you used to run weekly — they're concentrated into the last 5-10 sessions before the last Tuesday.
Substitute NIFTY weeklies for short-dated directional bets when you want a Tuesday clock; NIFTY and BANK NIFTY are correlated, though BANK NIFTY's higher beta means a NIFTY option won't capture the full banking-sector swing.
Mind the gap in instruments. Intraday BANK NIFTY traders who relied on near-zero-DTE premium now either trade the monthly's higher-priced options (more capital, slower decay) or move to NIFTY weeklies — there is no longer a cheap weekly BANK NIFTY equivalent.
Common misreads
- Looking for (or quoting strategies that assume) a BANK NIFTY weekly option — it no longer exists.
- Expecting weekly-style fast decay from a BANK NIFTY monthly early in its life — theta is gentle until the final week or two.
- Assuming a NIFTY weekly fully hedges a BANK NIFTY position — BANK NIFTY's higher beta leaves residual risk.
Key takeaways
- BANK NIFTY weekly options were discontinued (SEBI, Nov 2024); it's monthly-only now.
- BANK NIFTY monthly expires the last Tuesday of the month.
- Monthly = slower daily theta, larger premium — no more cheap fast-decay weekly tickets.
- Expiry-week decay/pinning concentrates into the last 1-2 weeks before the last Tuesday.
- For a short-dated Tuesday clock, NIFTY weeklies are the substitute — but they under-capture banking beta.
BANK NIFTY after the weekly
When does Bank Nifty expire now?
Monthly only, on the last Tuesday of the month. Its weekly option was discontinued under SEBI's November 2024 rule limiting each exchange to one weekly index expiry (NSE chose NIFTY). There is no weekly BANK NIFTY contract anymore.
Why did my Bank Nifty options strategy stop working after 2024?
If it relied on weekly options — cheap premium, fast daily decay, a fresh contract every week — it depended on an instrument that no longer exists. The monthly contract decays far more slowly day-to-day and costs much more in absolute premium, so weekly-tuned strategies don't transfer directly.
What's the best substitute for Bank Nifty weekly trades?
For short-dated directional views, NIFTY weeklies (Tuesday) are the closest liquid substitute — but BANK NIFTY is higher beta, so a NIFTY option captures only part of a banking-sector move. For decay/pinning plays, use BANK NIFTY's own monthly expiry week, where those dynamics now concentrate.
Does Bank Nifty still have monthly futures and options?
Yes. Only the weekly options were removed. BANK NIFTY monthly futures and monthly options continue to trade, expiring the last Tuesday of the month, and remain liquid, large-notional instruments.
Is the last Tuesday the same as NIFTY's monthly expiry?
Yes — both NIFTY and BANK NIFTY monthly contracts expire on the last Tuesday of the month, so the month-end expiry is a combined event across the major NSE index products. (SENSEX, on the BSE, is the last Thursday.)
