The VIX term structure illustrates, by maturity, expectations of market volatility conveyed by S&P 500 (SPX) stock index option prices.
CBOE calculates these expectations by applying the VIX methodology to standard SPX option maturities.
Please refer to the VIX white paper
for a description of this methodology.
The relationship between the constant 30-day maturity VIX Index and the S&P 500 is of interest to market participants.
Similarly, historical VIX term structures can offer insights into how the market's expectation of volatility of the S&P 500 has changed over time in response to market conditions.
Market analysts and traders can use VIX term structure data to see how market expectations on volatility compare to their own expectations.
The VIX term structure is also useful for investors looking to trade products based on forward volatility, such as VIX futures and options.
The implied volatility term structure observed in SPX options markets is analogous to the term structure of interest rates observed in fixed income markets.
Similar to the calculation of forward rates of interest, it is possible to observe the option market's expectation of future market volatility through use of the SPX implied volatility term structure.
For a discussion of deriving forward implied volatility from the SPX implied volatility term structure please review the VIX futures primer.
