The CBOE Volatility Index (VIX), nicknamed the "fear gauge," measures the market's expectation of S&P 500 volatility over the next 30 days, derived from S&P 500 options pricing. It is the world's most-watched market sentiment indicator.
The ranges below aren't a prediction of where CBOE VIX (Fear Index) will land — they're what its own typical daily move (5.0–9.0%) implies, projected forward from the live price above. Read them as a probability band, the same way you would the Tomorrow Prediction section.

The VIX is calculated from the prices of a wide range of S&P 500 index options with just under 30 days to expiration, using a formula that extracts the market's implied expectation of future volatility. When options traders bid up the price of both put and call options simultaneously — reflecting expectation of large moves in either direction — the VIX rises. It is a forward-looking measure of expected volatility, not a measure of past price swings.
The VIX and S&P 500 have a strong historical inverse relationship — when stocks sell off sharply, demand for downside protection (put options) surges, pushing the VIX higher. This relationship is not perfectly mechanical but is consistent enough that VIX spikes are frequently used as a shorthand signal for "the market is in a stressed, fearful state" rather than requiring traders to check the S&P 500 level directly.
VIX readings below 15 typically indicate a complacent, low-volatility market environment — historically, extended periods this low have sometimes preceded corrections as markets become vulnerable to surprise shocks. Readings of 20–25 suggest elevated but not extreme concern. Readings above 30 indicate genuine fear, and historically, VIX spikes above 40 have coincided with major market dislocations including the 2008 financial crisis and the 2020 pandemic crash, often marking periods that later proved to be buying opportunities in hindsight.
VIX below 15 = complacent market, often precedes corrections. VIX 20–25 = elevated concern. VIX above 30 = genuine fear and potential capitulation buying opportunity, historically.
A sharp VIX spike typically signals broad global risk-off sentiment that extends well beyond US markets — triggering FII selling in Indian equities, Rupee weakness, and gap-down opens on GIFT Nifty. Because the VIX reflects institutional positioning in the world's largest and most liquid equity market, it often moves before Indian-specific news catches up, making it a useful early-warning signal for Indian traders monitoring overnight global conditions.
NSE calculates its own "India VIX," derived from Nifty 50 options prices using a similar methodology to the CBOE VIX, but reflecting Indian-specific volatility expectations rather than US market conditions. India VIX and the US VIX often move together during genuinely global risk events but can diverge meaningfully during periods driven by India-specific catalysts like Budget announcements or RBI policy surprises — worth checking both rather than assuming they always tell the same story.
