Contango and Backwardation
Futures-curve conditions where later contract prices trade above or below nearby prices or spot value.
Contango and backwardation describe the shape of a futures curve. In contango, later futures contracts trade above nearby contracts or spot value. In backwardation, later futures contracts trade below nearby contracts or spot value.
The curve shape matters because it changes roll yield, hedge cost, inventory economics, and how a trader interprets the relationship between cash and futures markets.
Basic Relationships
In a simple comparison:
For a spot-to-futures comparison, the same idea is often framed as later futures trading above or below current spot value. The exact interpretation depends on the commodity, delivery location, settlement method, and contract month.
Why Curves Slope
| Curve shape | Common drivers | Practical effect |
|---|---|---|
| Contango | Financing, storage, insurance, abundant nearby supply, seasonal carry. | Rolling long futures can be costly if later contracts are more expensive. |
| Backwardation | Tight nearby supply, high immediate demand, low inventories, high convenience yield. | Rolling long futures can be favorable if later contracts are cheaper. |
| Flat or mixed curve | Balanced carry, seasonal patterns, contract-specific delivery constraints. | Curve analysis must move month by month. |
The CFTC describes futures markets as price-discovery and risk-transfer markets. See CFTC futures basics and its explainer on the economic purpose of futures markets.
Common Mistakes
- Treating contango as automatically bearish or backwardation as automatically bullish.
- Comparing the wrong delivery months.
- Ignoring storage constraints, delivery points, and seasonal demand.
- Using front-month futures to infer the whole curve.
- Forgetting that roll return can differ from spot-price return.
