Contango
Longer-dated contracts priced above shorter-dated
What is Contango?
Contango Contango is a market structure where the price of a future-dated instrument is higher than the spot or near-dated price. In volatility markets, contango means longer-dated implied volatility is higher than short-dated IV — the upward-sloping "normal" term structure of equity options. The term originates in commodities markets (the carrying cost of physical goods through time creates upward-sloping futures curves). In options, the analogous phenomenon is the typical pattern where 30-DTE IV is lower than 90-DTE IV, which is lower than 1-year IV, in regular market conditions. VIX futures markets typically trade in contango. VIX spot might trade at 16, the front-month VIX future at 18, and the 6-month VIX future at 21. This contango is structural — it reflects the market's pricing of uncertainty growing with time horizon. The persistent contango is also why short-VIX-futures strategies (like the old XIV product or SVXY ETF) earn a roll-yield premium most of the time and then suffer catastrophic losses during backwardation regimes. For options traders, contango in the term structure has specific implications: - **Calendar spreads benefit**. When term structure is in steep contango, the back-month (long) leg has more vega while the front-month (short) leg has more theta decay. This is the structural edge calendar spreads target. - **Front-month premium selling is less attractive**. Short-dated IV is artificially low in contango. The premium-per-day-of-decay ratio is worse than in backwardation regimes. - **Long volatility positions in calm markets are expensive**. Contango means you're paying for long-dated vol that's pricing in more uncertainty than current realized vol justifies. The most useful contango monitor for equity options is the VIX-to-VIX3M ratio. Persistently below 0.85 = deep contango. Above 1.0 = backwardation. Most days the ratio sits in the 0.88-0.95 range. Contango regimes typically last for months or years. The 2017-2019 stretch was a famous extended-contango period in VIX futures. The 2022-2024 period has been similar, with occasional brief backwardation spikes that mean-reverted within days.

Example
VIX spot at 14, VIX 30-day future at 16, VIX 6-month future at 20. The futures curve is in steady contango. A short VIX-futures position would earn the roll-down each month — but a sudden vol spike could produce losses several times larger than years of accumulated contango gains.

Frequently Asked Questions
What is contango in options?
Contango is when longer-dated implied volatility is higher than short-dated IV — the upward-sloping 'normal' term structure. VIX 6-month futures at 21 with VIX spot at 16 is a typical contango pattern. Most regular market regimes are in contango.
How long does contango typically last?
Contango regimes typically last months to years. The 2017-2019 period was a famous extended-contango stretch in VIX futures. Brief backwardation spikes mean-revert quickly (often within days), so the dominant regime is contango most of the time.
How do I trade contango?
Calendar spreads benefit from contango — buy back-month options, sell front-month options. The back-month has more vega; the front-month has faster theta decay. Short-VIX-futures products earn roll-yield in contango but face catastrophic losses during backwardation transitions.
