VIX Futures

VIX futures were launched by the CBOE Futures Exchange in 2004, providing the first exchange-listed means to trade forward implied volatility directly. Each VIX futures contract has a notional value of $1,000 times the VIX settlement price and is cash-settled against the VIX SOQ calculation on the Wednesday morning settlement date. Multiple expiration months are listed simultaneously, creating a complete term structure of implied volatility visible in real time.

The term structure of VIX futures — plotting futures prices against their sequential expiration months — is one of the most watched indicators of market regime in U.S. equity markets. Under normal conditions, the term structure is upward sloping (contango): near-dated VIX futures trade below longer-dated contracts because near-term realized volatility tends to mean-revert back toward lower levels, and because there is time-value in future uncertainty. During market stress episodes, the term structure inverts (backwardation): the front-month VIX futures spike above deferred contracts as traders price in elevated near-term fear without expecting elevated volatility to persist.

The behavior of the VIX term structure in contango is the fundamental risk in short volatility exchange-traded products such as the ProShares Short VIX Short-Term Futures ETF (SVXY). When contango is steep, rolling from expiring front-month contracts into the next month involves selling low and buying high, creating a persistent negative roll yield that erodes the value of short-VIX positions over time in the absence of a volatility increase. The February 2018 VIX shock destroyed several inverse-volatility exchange-traded products in a single session, demonstrating the tail risk inherent in systematic short-volatility strategies.

Institutional uses of VIX futures include portfolio hedging (buying front-month VIX futures as a low-cost hedge against equity drawdowns), volatility arbitrage between the futures term structure and the implied volatility surface of S&P 500 options, and calendar spread trading to express views on when volatility will revert or remain elevated. Long-short volatility funds actively trade VIX futures spreads across the full term structure visible at CFE.

VIX futures also serve as the primary hedge for dealers managing VIX options books and for issuers of VIX-linked structured products. The interaction between large institutional hedging flows in VIX futures and the mechanical roll schedules of volatility ETPs creates predictable supply and demand patterns that sophisticated traders attempt to anticipate and trade around, particularly around monthly VIX settlement dates.
