IV skew is the difference in implied volatility across strike prices for SBIN options on NSE. In most markets, OTM puts carry higher IV than OTM calls — this is called put skew, reflecting demand for downside protection. When OTM calls carry higher IV it is called call skew, often seen before earnings or in strongly bullish markets. The current SBIN ATM IV is 2930.0% with relatively flat skew.

A steep put skew for SBIN means OTM put options are expensive relative to calls — the market is pricing in tail-risk to the downside. This makes selling OTM puts relatively attractive (collect elevated premium) but buying put protection expensive. A steep call skew (unusual) signals bullish sentiment or an upcoming event. Traders use the IV skew to select strikes that offer the best premium relative to directional risk.

SBIN's current nearest-expiry ATM implied volatility is 2930.0%, compared to the 30-day ATM IV of 2683.0%. The IV Rank of 0 out of 100 contextualises this reading against SBIN's own 52-week IV range — low, meaning options are cheap relative to their historical range.
