NIFTY IV skew + term structure — where fear is priced.
The full implied-volatility surface US options pros watch all day, rebuilt for Indian markets. 25-delta put/call IV, 5% OTM skew, and ATM IV across weekly → next-week → monthly → quarterly expiries. Read fear asymmetry, event premium, and term-structure regime at a glance.
How to read it
IV at 25Δ put minus IV at 25Δ call. High positive = fear heavily priced; negative = calls richer (upside chase). In Indian index options, a +2 to +4 pp skew is normal. Above +5 flags genuine stress. Below −2 is complacency.
IV at strike closest to spot×0.95 minus IV at strike closest to spot×1.05. Similar interpretation, easier to reason about intuitively. Useful when 25-delta strikes are illiquid.
ATM IV across successive expiries. Normal: mild contango (back-month IV higher). Flat or inverted structure = event premium in the front — results, budget, expiry Thursday. Wide contango can signal dealers selling front-month vol into a calm tape.
Trade setups from the surface
- • Skew > +5 pp AND VIX compressed. Classic fear-priced-into-options setup. Put-credit spreads near the 25Δ strike collect rich premium; risk: the tail it's pricing might be real.
- • Skew < 0 (call-skew). Upside speculation pricing. Calendar call-spread structures or ratio call spreads work when this is combined with a bullish short-term view.
- • Backwardated term structure. Front-month IV rich → calendar spreads (sell front, buy back-month) collect the contango when the event passes. Classic earnings-season play.
- • Steep contango + low VIX. Back-month straddle buying cheap — directional conviction pays.
