Contango
Contango is a term-structure shape in which the price of an otherwise comparable futures or forward contract rises with time to maturity: a nearer-dated contract trades below a later-dated contract. It describes today's curve, not where the spot price must move next.
A futures contract is an agreement to buy or sell something at a set date in the future — oil next month, oil next summer, and so on. At any moment you can line those dates up and see what the market charges for each one. That lineup is called the curve.
Contango just means the lineup slopes upward: the further out the date, the more the contract costs. It is the market's normal posture for many things, partly because holding something for longer — storing it, financing it, insuring it — costs money, and the price for later delivery absorbs that.
The key thing beginners get wrong: an upward slope is not a prediction that prices will rise. It describes what different delivery dates cost today, nothing more.

Current observation
This dated measurement is an instance of the concept, not the concept itself. It updates when the verified source dataset changes; the as-of date below is the freshness contract.
The proxy is in contango, 95 consecutive trading sessions into the current regime. This labels a curve shape; it is not a trade recommendation.

Why it matters
The curve determines part of the carry experienced by a position that must replace an expiring contract. A long position rolling from a cheaper near contract into a more expensive later contract starts from an adverse price gap if the curve is unchanged; a short position starts from the other side of that gap.
Contango has different economic causes in different markets. Storage, financing and convenience yield matter in physical commodities; funding and dividend assumptions matter in equity-index futures; volatility curves reflect the market's price for protection across horizons.
Because it is a relative-price state, contango is useful context rather than a directional forecast. Spot can rise or fall while the curve remains in contango, and the curve itself can change before a roll occurs.
Calculation and identification
For comparable contracts on the same underlying, a positive price slope from the near maturity to the later maturity is contango.
We compare Cboe's spot VIX and constant three-month VIX index. This is a transparent stress proxy. The tradeable VIX futures curve itself is a separate instrument.
Worked example
A two-contract curve
Suppose a near futures contract trades at 18 and a comparable later contract trades at 20.
- 1Compare the two maturities: 18 is below 20.
- 2The slope is (20 − 18) / 18 = 11.1% across that maturity interval.
- 3A long investor who must roll today would sell the 18 contract and buy the 20 contract, before fees and any subsequent curve movement.
The 2-point gap is not a guaranteed 2-point loss. Realized return also depends on spot, convergence, when and how the position rolls, and how the curve changes.
Where it can mislead
- 01
Contango does not mean the market expects spot to rise by the slope of the curve. Futures prices embed carry, risk premia and market-specific mechanics as well as expectations.
- 02
“Negative roll yield” is shorthand for a longer return equation. Contract convergence, curve movement, collateral return, fees and the product's roll schedule all matter.
- 03
A two-point comparison can miss humps or inversions elsewhere on the curve. Always state which maturities and settlement times were used.
- 04
Our VIX/VIX3M ratio uses two Cboe indexes. It usually conveys the same near-versus-later stress shape traders discuss, but it is not a substitute for pricing actual VIX futures or volatility ETPs.

Frequently asked questions
Is contango active in the VIX proxy now?
As of the 2026-08-21 close, active — ratio 0.82. The proxy is in contango, 95 consecutive trading sessions into the current regime. This labels a curve shape; it is not a trade recommendation. The observation uses VIX/VIX3M rather than tradeable VIX futures.
How common has contango been in this VIX proxy?
From 2009-12-31 through 2026-08-21, contango accounted for 92.3% of 4,185 daily observations under the strict 1.00 threshold. This frequency describes this proxy and sample, not every futures market.
Does contango mean the spot price will rise?
No. Contango is the shape of prices across maturities at one point in time. It can reflect financing, storage, insurance demand and risk premia; spot can subsequently rise or fall.
Does contango guarantee a loss for a long futures position?
No. Rolling into a higher-priced contract creates an adverse starting gap if the curve is unchanged, but total return also depends on convergence, spot and curve movement, collateral, fees and the exact roll method.
Is VIX/VIX3M the same as the VIX futures curve?
No. VIX and VIX3M are Cboe indexes representing different implied-volatility horizons. Their ratio is our freely reproducible term-structure proxy; actual VIX futures are tradeable contracts and can differ around maturities and settlement.
