Contango

OVERVIEW

Contango is a futures market structure in which longer-dated contracts trade at higher prices than nearer-dated contracts, with the entire futures curve sitting above the current spot price. It represents the market's way of pricing in carrying costs — storage, insurance, and financing — for commodities held over time.

Note

Contango is the normal state for most futures markets. When contracts are rolled forward, holders of long positions systematically lose money to the higher price paid for the further-out contract.

For non-storable assets like volatility, contango reflects the risk premium demanded by sellers of future exposure rather than physical carrying costs.

IDENTIFICATION

A market is in contango when the following condition holds:

F(t₂) > F(t₁) > S,  where t₂ > t₁
Variable Meaning
F(t) Futures price for expiration t
S Current spot price
t₁, t₂ Near and far expiration dates

Roll yield measures the expected loss per period of maintaining a long position by rolling contracts forward:

Roll yield ≈ (F(t₂) − F(t₁)) / F(t₁)

No-arbitrage cost-of-carry bound (storable commodities):

F = S × e^((r + u − y) × T)
Variable Meaning
r Risk-free rate
u Storage cost
y Convenience yield
T Time to expiration

When (r + u) exceeds y, the market is in contango.

WORKED EXAMPLES

VIX Futures — Perpetual Contango

VIX spot at 14.5 on a typical quiet trading day:

Contract Price
April 15.2
May 16.8
June 17.9
July 18.6

Note

This is a steep contango curve. Holders of VXX (short-dated VIX futures ETN) bleed approximately 0.3% per trading day from rolling the front month to the second month at a higher price. Annualized decay exceeds 60% in quiet volatility regimes.

UVXY (1.5× leveraged VIX ETN) has lost more than 99.99% of its value since inception through a combination of reverse splits and contango bleed.

WTI Crude Oil — Mild Contango

Contract Price
Spot $76.00
June $76.80
December $78.50

Approximately $2.50 over spot nine months out — roughly matching short-term rates plus storage costs.

HOW TO USE

Reading Contango as a Trader

Strategy How Contango Applies
Producer hedging Sell futures into a contango curve to lock in higher-than-spot prices for forward production
Long ETF avoidance Avoid buy-and-hold long positions in contango ETFs; roll decay erodes returns over time
Volatility carry trade Systematically short front-month VIX futures to collect roll yield as contracts converge toward lower spot VIX
Spread trading Short contracts trading unusually rich relative to neighbours; long surrounding contracts to bet the hump flattens

Tip

Funds like SVXY institutionalize the volatility carry trade. It wins in over 80% of periods but carries severe tail risk. On February 5, 2018, XIV lost 96% overnight and was subsequently liquidated.

Identifying Actionable Curve Kinks

When a single expiry trades unusually rich against adjacent months:

  1. Identify the elevated contract (e.g. July rich vs. June and August)
  2. Short the elevated contract
  3. Long a basket of the surrounding contracts
  4. Hold until the hump reverts to a smooth curve

LIMITATIONS AND MISCONCEPTIONS

Note

Contango does not predict the direction of the underlying asset. A market in steep contango can still rally sharply. VIX has spiked above 80 from contango states — the curve prices term structure and risk premium, not the future spot path.

Misconception Reality
Contango means the underlying will fall Contango reflects carrying costs and risk premium only
Super contango is always temporary Extreme contango can persist during severe oversupply events
Contango is a permanent structure Markets flip to backwardation during supply shocks, demand spikes, or fear events

Super contango — contango exceeding storage economics — signals severe oversupply. In April 2020, front-month WTI went negative while June contracts held above $20 because physical storage at Cushing, Oklahoma was exhausted.

Contango is not constant. VIX futures flipped sharply to backwardation in:

  • March 2020
  • March 2023
  • August 2024

These are precisely the periods when short-volatility traders suffered the largest losses.
