India VIX

What is India VIX?

India VIX, short for India Volatility Index, measures the expected volatility of the Indian stock market, specifically the Nifty 50 index, over the next 30 calendar days. It is calculated by the National Stock Exchange (NSE) using the best bid-ask prices of near and next-month Nifty options. India VIX is often called the "fear gauge" as it rises during times of market uncertainty and falls when the market is stable. Higher values indicate greater expected volatility and risk, while lower values imply market stability and confidence.

How is India VIX Calculated?

India VIX represents the expected volatility of the NIFTY 50 index over the next 30 days. Its value is calculated using NIFTY option prices and key market parameters:

• Time to Expiry: Measured in minutes for precise calculation.
• Interest Rate: Uses the risk-free rate, typically the NSE MIBOR rate for the relevant tenure.
• Forward Index Level: Derived from NIFTY futures prices to determine the at-the-money (ATM) strike.
• Option Selection: Out-of-the-money (OTM) calls have strikes above ATM; OTM puts have strikes below ATM.
• Bid-Ask Quotes: Prices of selected OTM options are used to calculate variance for near- and mid-month expiries.
• Weighting: Each option is weighted proportionally to its average bid-ask price and inversely to its strike price.
• Final Calculation: Variances are interpolated to 30 days, square-rooted, and multiplied by 100 to obtain India VIX.
