Spot Price vs. Futures Price

The spot price is what you pay for immediate delivery; the futures price is what you pay for delivery months away. The gap between them—the basis—tells you everything about storage costs, interest rates, supply confidence, and whether the market fears scarcity.

Spot price is immediate settlement

The spot price is the cash price for a commodity delivered now. You walk into a refinery, a grain elevator, or an over-the-counter metals desk and buy barrels, bushels, or ounces for immediate handoff. In traded markets, spot usually means settlement within 2–3 days. In less liquid segments, it might mean “today” or even “this week.” Either way, the clock has started: you have the thing.

This matters because spot trades are the real economy price. If you manufacture orange juice, you might buy spot orange juice concentrate to fulfil standing orders. If you run an airline, you buy spot jet fuel (or very near-term futures) to fill tanks. Spot is where physical supply and demand meet directly.

Futures price looks ahead

A futures-contract is a standardized agreement to buy or sell a set quantity of the commodity at a set price on a set future date. The July wheat contract trades now but settles in July. The December crude contract is locked in December. Unlike spot, futures prices embed expectations: Will inventories be tight in December? Will interest rates rise? Will farmers plant more?

This forward look is why futures-contracts exist: producers lock in prices, users secure supply, and speculators bet on these expectations.

The basis: carrying cost and expectations

The difference between the spot price and the futures price is called the basis. If spot gold is $1,950 per ounce and December futures are $1,970, the basis is $20 per ounce.

This gap is never random. It reflects:

• Storage and insurance: Holding a barrel of oil from now until December costs money—warehouse fees, insurance, handling. That cost has to be reflected in the futures price or there’s an arbitrage.
• Financing cost: If you buy spot gold today and sell December futures, you are effectively lending money for six months. The futures price must compensate you for interest-rate risk.
• Convenience yield: Sometimes holding physical right now is worth paying a premium. An oil refinery values having fuel in hand if supplies are disrupted. This “convenience” of physical ownership reduces the futures premium, making spot expensive relative to futures—even negative basis.

Because these costs are measurable, the basis is predictable and tradable. Traders arbitrage the gap; if the futures contract gets out of line with carrying costs plus the spot price, arbitrageurs buy cheap and sell dear until the basis snaps back.

Contango and backwardation

When the futures price is above the spot price (futures premium), the market is in contango. This is the normal state: you expect to pay for storage and carry, so deferred delivery is more expensive. Contango curves gently upward months into the future and eventually flattens.

When the futures price is below spot—rare but dramatic—the market is in backwardation. This signals fear: supply is tight now, and the market is willing to pay a premium for immediate barrels or bushels. Backwardation often appears during supply shocks (refinery outages, harvest failures) and signals that physical shortage is driving spot up relative to the expectation for normalcy further out.

A sharp backwardation that lasts weeks is a red flag to users (manufacturers, refiners, utilities) that they should book supplies now. To producers, it signals: sell all you can right now.

What the gap tells you about the market

The spot-futures gap is transparent market sentiment. When contango widens—say, spot is $60 and next-month futures are $65—the market is saying “supply is comfortable, storage is safe, don’t worry.” When backwardation steepens—spot $65, next month $60—the market is saying “we need this now.”

This is why price-discovery in futures markets matters: the forward curve (the line of prices from January through December) is the best public guess of future supply, demand, and fear. Governments, central banks, and industry watch these curves to sense building inflation (if contango is flattening and spot is rising) or gluts (if backwardation collapses).

Spot and futures drift apart and converge

Over time, spot and futures prices converge. When December futures contract expires, it must settle at the spot price (or close to it)—otherwise there is free money on the table and arbitrageurs step in. As the contract nears expiry, the two prices merge. Then the next contract’s futures price becomes the forward reference, and the cycle repeats.

This convergence is how futures prices stay honest. If December wheat futures and December spot wheat were allowed to diverge permanently, hedgers would stop using futures, and the market would lose its utility. The certainty of convergence is what makes futures work.
