Contango and Backwardation

Line up a commodity's prices across delivery months and you get the forward curve. Sometimes later months cost MORE than the near month; sometimes they cost LESS. Those two shapes have names — contango and backwardation — and each is the market voting, in real dollars, on where it expects prices and costs to go.

When later-dated contracts are priced higher than nearer ones, the curve is in contango — the normal state for storable goods, because holding physical stuff costs money (storage, insurance, financing) and the future price bakes that in. A contango curve slopes gently uphill to the right. It usually signals comfortable supply and no urgency to get the goods right now.

When nearer contracts cost MORE than later ones, the curve is backwardated — buyers are paying a premium for the goods immediately, which typically means tight supply or a scramble for the physical thing today. A backwardated curve slopes downhill to the right. It's the market's way of shouting that right now matters more than later.

Here's the part that costs real people real money. To stay in a commodity via futures, you must repeatedly sell the expiring contract and buy the next month — 'rolling.' In contango you sell low and buy higher each time, a steady bleed; in backwardation you sell high and buy lower, a steady tailwind. This is why a commodity fund can go DOWN over a year the underlying commodity went up — the roll quietly ate the difference.

You don't need to trade the curve to profit from reading it. Deep backwardation whispers 'physical shortage, urgency now'; steep contango whispers 'plenty in storage, no rush.' Watching a curve flip from one to the other is watching supply-and-demand psychology change in advance of the headlines. That's the payoff: the curve is a sentiment gauge disguised as a maturity ladder.
