Plot the premium of each futures expiry over spot and you get a curve. Its shape — sloping up or down — is the term structure, and it encodes how the market prices forward demand, carry, and stress. Reading it is foundational desk literacy.
Contango: the normal upward slope
In contango, longer-dated futures trade at a higher premium to spot than nearer ones — an upward-sloping curve. This is the typical state in a healthy or bullish crypto market: traders pay up to hold leveraged long exposure into the future, so the premium widens with time to expiry.
Contango is what makes the cash-and-carry trade work: long spot, short the premium future, harvest the convergence to spot at expiry. Steep contango means fat carry, which pulls in basis traders until the premium compresses.
Backwardation: the stress signal
In backwardation, nearer-dated futures trade richer than later ones, or futures dip below spot — a downward slope or inversion. In crypto this is less common and more informative: it typically signals immediate stress, aggressive spot demand the futures have not caught, or a rush for near-term exposure.
A flip from contango into backwardation is a regime change worth respecting. It often accompanies sharp spot moves, deleveraging, or a scramble for immediate hedges.
What the slope tells you
Read the curve as a sentiment and positioning gauge:
- Steep contango — strong forward demand, fat carry, leveraged longs paying up. Constructive but can signal froth at extremes.
- Flat curve — neutral, balanced demand across the term.
- Backwardation — near-term stress or intense spot demand. Often coincides with local extremes.
The change in shape matters more than any snapshot: a flattening curve as a rally ages warns that forward demand is fading even if spot still grinds.
Trading the roll
For anyone holding dated futures, term structure is a direct cost or benefit. In contango, rolling a long position to the next expiry means paying the premium repeatedly — a carry bleed for systematic longs. In backwardation, the roll can pay you. Index and ETF products that hold futures are quietly exposed to this, which is why the curve's shape affects them beyond simple price.
Takeaway
The futures term structure slopes up in contango (normal, bullish, fat carry) and inverts in backwardation (stress or intense spot demand). Steep contango fuels the cash-and-carry trade; a flip to backwardation flags a regime change. Watch the change in shape over any single reading, and remember the roll is a real cost in contango and a tailwind in backwardation.
