When a curve segment is backwardated, the earlier contract trades above the later contract. For a front-minus-back calculation, the spread is typically positive.
Front month = 525, deferred month = 510. Front minus back = +15.
Steepening backwardation
If the front contract strengthens further relative to the back month, the spread rises and the downward slope between those contracts becomes steeper.
Flattening backwardation
If the deferred month catches up or the nearby premium fades, the spread narrows.

Open Forward CurveWhy backwardation can change quickly
Nearby supply shocks, demand changes or inventory releases can alter the premium on immediate delivery faster than farther-out expectations change.
Research the regime, not just the label
Compare the current relationship with historical seasons. A spread pattern that worked during moderate backwardation may behave differently during an extreme nearby squeeze.
Connect curve structure with seasonality
After reviewing the curve, test the exact month pair across historical seasonal windows.
Analyze the SpreadBackwardation can concentrate risk in the nearby leg
When prompt supply is tight, the nearby contract can become unusually sensitive to inventory, logistics and short-term demand. A calendar spread that appears historically familiar may therefore behave very differently during an extreme squeeze.
Before relying on seasonality, compare the current amount of backwardation with historical ranges. Extreme structure is a warning that the current regime may not resemble the average year.
What to monitor as backwardation changes
- Whether the nearby premium is widening or narrowing.
- Whether the change is limited to one pair or visible across the front of the curve.
- Whether inventories or physical availability have changed.
- Whether the seasonal spread pattern behaved similarly in past backwardated regimes.
The goal is to understand the mechanism behind the move, not simply attach a bullish label to the curve.

Frequently asked questions
Is contango bullish or bearish?
Not by itself. Contango describes the relationship between futures delivery months, not a directional forecast for the underlying market.
Is backwardation always caused by a shortage?
No. Tight nearby supply can contribute, but curve shape can also reflect demand, inventory, financing, convenience value and expectations.
Can a curve contain both contango and backwardation?
Yes. A mixed curve can have rising sections and falling sections at the same time.
Why does curve structure matter for calendar spreads?
A calendar spread is one segment of the curve, so changes in the curve directly change the relative value between the two delivery months.
Research the curve and the spread together
Use the Forward Curve for current structure, then compare the same contract relationship in historical seasonal data.
