Contango and Backwardation in Futures Markets Explained

Contango backwardation futures describe how contract prices compare with expected spot prices over time, and the distinction matters because prices must converge as a contract reaches maturity.

What contango and backwardation futures prices signal

Contango occurs when a futures price sits above the expected spot price at the contract’s future delivery date. If that expectation does not change, the futures price has to move lower as the contract approaches maturity. A trader holding a long position could lose value during that decline, even if the market’s general price level appears stable.

Normal backwardation describes the reverse relationship: the futures price is below the expected future spot price. As maturity nears, the contract price must rise toward that expected spot level if the expectation remains unchanged. That movement can benefit a speculator holding a net long position, though a changing spot price can alter the outcome.

These terms are easy to mix up with the shape of a futures curve. A curve is a snapshot of prices across delivery dates. A market is called normal when prices are higher for contracts with later maturities, and inverted when distant contracts are priced below nearer ones or the spot price. Contango and normal backwardation, by contrast, describe a futures price in relation to the expected spot price and how that relationship resolves over time.

The distinctions matter because the shape of a curve today does not, on its own, establish what a particular contract will earn. Market expectations can change. A curve can also look different across maturities, rather than rising or falling in a uniform line.

Crude oil is one example of a market where the curve can have a more complicated shape. Its futures curve is traditionally described as humped: normal over shorter maturities, then inverted at longer ones. A single label may therefore fail to describe every part of the curve.

Storage, financing and the value of holding a commodity

Supply and demand help set futures prices, but the costs and benefits of holding the underlying asset also matter. For a physical commodity, storage can add expense. Financing the purchase ties up capital, while the cost of carry brings those financing and holding costs into the pricing relationship.

There can also be a benefit to having the physical commodity available. This is called convenience yield. A business that holds a tangible resource may value access to it, rather than relying on a futures contract to provide exposure. When that practical benefit is high, it can influence how nearby and later delivery prices compare.

Financial assets have their own ownership benefits. A shareholder, for example, may receive a dividend. The source of value differs from the convenience yield associated with a physical commodity, but both can affect the appeal of owning the asset rather than holding a derivative tied to it.

These factors feed into market participants’ views about the future spot price. Buyers and sellers agree on a futures price based on their expectations and the costs or benefits attached to holding the asset. As new information changes those views, the futures price can change too. The curve is therefore a record of current pricing across maturities, not a guarantee of where spot prices will later land.

An unexpected supply disruption illustrates how quickly the relationship can change. If a crisis creates a sharp shortage, the spot price may jump. That move can push a market from contango into backwardation. The change reflects the altered balance between immediate availability and future supply, rather than a fixed property of the commodity.

Why futures prices converge at maturity

A futures contract and the spot market cannot remain far apart as the delivery date arrives. The gap between the futures price and spot price is known as the basis. At maturity, the prices must meet. Otherwise, traders could exploit the difference through arbitrage, buying in one market and selling in the other for a near risk free gain.

That convergence is central to understanding how a contract behaves over its life. A futures position is an obligation tied to the contract, not an option to decide later whether to buy. Someone who takes a long position agrees to purchase under the contract’s terms. For instance, with a spot price of $60 and a one year futures price of $90, the long position commits to a purchase at $90 in one year.

The example also shows why the curve’s shape and the expected future spot price should not be treated as interchangeable. If the expected spot price at that date is $60, a futures contract priced at $90 is above that expectation, a contango situation under the definition used here. If the expected price stays at $60, the contract price must fall as the delivery date gets closer.

The difference can be tracked by following the same delivery contract through time. A December 2023 contract priced at $100 today could still be $100 one month later. If it rises to $110, that price movement is consistent with normal backwardation in the example; if it falls to $90, it is consistent with contango. The labels depend on the relationship to the expected future spot price, not simply on whether a chart slopes upward or downward across different delivery months.

In practice, expectations do not stay fixed. A new estimate of future supply, demand or carrying costs can change the expected spot price and the contract’s value. The movement toward maturity is therefore not always a straight decline or rise. Convergence describes where prices must meet at expiry, while the path there reflects changing market information.

Frequently Asked Questions

What is contango in futures?

Contango is a condition in which a futures price is above the expected spot price at the contract’s future maturity. If expectations hold, the futures price moves down toward that level as maturity approaches.

What is backwardation in futures?

Backwardation, also called normal backwardation in this context, occurs when a futures price is below the expected future spot price. If that expectation holds, the contract price moves up toward it as maturity nears.

What is backwardation and contango?

They describe opposite price relationships. Contango places the futures price above the expected future spot price, while backwardation places it below.

Is contango or backwardation more common?

The material here does not establish that either condition is more common across commodities or over time. The curve can vary with supply and demand, storage and financing costs, and the benefit of holding the physical asset.

What is contango and backwardation in futures markets?

They describe how a futures contract is priced relative to the expected spot price at maturity. In either case, the contract price must converge with the spot price when the contract expires.
