Contango and Backwardation: How to Read the Futures Curve
If you trade futures, the price on your chart is only part of the story. Every contract has an expiry, and the same underlying market trades at different prices across different expiry months. Line those prices up by delivery date and you get the futures curve (the term structure). Its shape has a name, it has consequences for your cost of holding a position, and it quietly tells you what the market thinks about supply and demand. The two shapes you need to know are contango and backwardation.
Contango: later is more expensive
A market is in contango when contracts further out cost more than near-term ones. The curve slopes upward. This is the "normal" state for many markets because holding the physical asset until a later delivery has costs: storage, insurance, and financing. The further-dated contract bakes those carrying costs into its price. Crude oil, natural gas, and grains often sit in contango in calm conditions.
Backwardation: later is cheaper
A market is in backwardation when near-term contracts cost more than later ones. The curve slopes downward. This typically signals tight supply or strong immediate demand: buyers are willing to pay a premium to get the asset now rather than wait. A supply shock, a shortage, or a spike in spot demand can flip a market from contango into backwardation fast.
Why it matters: roll yield
Here is the part that hits your account. A futures position does not last forever; to stay in the market past expiry you roll from the expiring contract into the next one. That roll is where curve shape becomes real money:
How traders use it
Bottom line
Contango means later contracts are dearer (carrying costs dominate); backwardation means near contracts are dearer (scarcity dominates). The curve is not trivia: it sets your roll cost, hints at supply-demand pressure, and explains why a "buy and hold" futures or commodity-ETF position can drift away from the spot price you were watching. Check the curve before you assume the chart tells the whole story. Not financial advice; do your own research.

Why it matters: roll yield
Here is the part that hits your account. A futures position does not last forever; to stay in the market past expiry you roll from the expiring contract into the next one. That roll is where curve shape becomes real money:
- In contango, you sell the cheaper expiring contract and buy a more expensive later one. Each roll costs you a little. Hold a long position through repeated rolls in a contango market and roll yield bleeds away at your returns, even if spot price never moves. This is why many commodity ETFs underperform the spot commodity they track.
- In backwardation, the roll works in your favour as a long: you sell the pricier expiring contract and buy a cheaper later one, earning a positive roll yield.
How traders use it
- Read sentiment: a market sliding from contango into backwardation is flagging tightening supply or rising urgency, often before the headline spot price tells the same story.
- Mind your holding cost: if you carry positions over expiry, factor the roll into your edge. A steep contango can quietly erase a small expected gain.
- Calendar spreads: some traders trade the shape itself, going long one expiry and short another to profit from the curve steepening or flattening rather than from outright direction.
