Bank Nifty Option Chain Live

Reading the Bank Nifty chain

The table above lists every active Bank Nifty strike for the selected expiry — Calls left, Puts right, with open interest, change in OI, IV and LTP. The mechanics are the same as any option chain, but Bank Nifty behaves differently enough that reading it the same way as Nifty is a mistake.

How Bank Nifty differs from Nifty

Bank Nifty is a 12-stock index dominated by a handful of large banks, so it moves faster and further than Nifty on the same news — rate decisions, RBI policy, banking results. That shows up in the chain three ways. Strike spacing is wider (100 points vs. Nifty's 50), IV runs structurally higher, and OI concentrations shift more violently intraday. A resistance strike that held all morning can be overrun in one policy headline; confirm levels against fresh OI buildup rather than trusting standing OI alone.

Bank Nifty currently trades monthly expiries only — weekly Bank Nifty contracts were discontinued under SEBI's 2024 expiry rationalisation [VERIFY current expiry day]. That makes its OI structure stickier between expiries than Nifty's weekly-driven chain: levels persist longer, and the run-up to monthly expiry concentrates more unwinding into fewer sessions.

A practical routine

Before trading, note the highest Call-OI and Put-OI strikes from the summary above — the working range. Then check whether today's change in OI confirms or fights that range. On RBI and results days, watch IV before entering: buying options into an event at peak IV often loses money even when the direction is right, because IV collapses after the announcement.

FAQs

Does Bank Nifty still have weekly expiry?

No — weekly Bank Nifty contracts were discontinued under SEBI's expiry rationalisation; only monthly contracts trade now [VERIFY]. The expiry selector above shows all currently listed series.

Why is Bank Nifty IV higher than Nifty IV?

Concentration. Twelve stocks, dominated by a few banks, react sharply to rate and policy news, so the market prices in larger expected moves — which is exactly what IV measures.

What lot size applies?

Contract specifications have been revised more than once recently; the current lot size is shown with the contract details above rather than stated here, so it's always accurate.

Which strikes matter most intraday?

ATM ±3 strikes carry most of the day's volume and fresh OI. Deep OTM strikes show big OI numbers but often reflect old positioning, not today's view.

How do I trade RBI policy days using this chain?

Most professionals reduce naked option buying into the event (IV is at its peak) and watch post-announcement OI shifts to see which side writers are defending. The change-in-OI view immediately after the decision is the clearest read.
