Spot vs Futures Prices

What Is the Spot Price?

The spot price is the price for buying or selling something right now, for immediate delivery. If a jewelry manufacturer needs gold today, they pay the spot price. If an airline needs jet fuel delivered to its tanks this week, the transaction is priced close to the spot market. "Immediate" in practice usually means settlement within one or two business days, depending on the market — but the core idea is simple: pay now, receive now.

Spot prices are driven purely by current supply and demand. No guesswork about the future is baked in — just what buyers and sellers agree the commodity or asset is worth at this moment. Because of that, spot prices can move sharply when supply or demand shifts unexpectedly, such as when oil crashed below zero in April 2020 as storage facilities filled to capacity and physical holders had nowhere to put barrels.

What Is a Futures Price?

A futures contract is a legally binding agreement to buy or sell a fixed quantity of something at a fixed price on a specific future date. The price written into that contract is the futures price. It is not the price anyone pays today — it is the price both sides have locked in for a transaction that will happen weeks, months, or even years from now.

Because futures contracts are standardized — every contract for WTI crude oil, for example, covers exactly 1,000 barrels of a defined oil grade — they can be traded on an exchange just like shares of stock. Standardization is the key feature that makes futures liquid and transparent. You can read more about the mechanics in the guide What Is a Futures Contract?

Why Most Benchmarks Quote a Futures Price, Not Spot

When you look at a commodity price on a market-data table — crude oil, natural gas, corn, copper — the number you see is almost always the front-month futures price. The front month is the nearest upcoming delivery month still being actively traded. There are several reasons this has become the standard benchmark.

• Liquidity. Liquidity means how easily something can be bought or sold without moving the price. Front-month futures attract enormous trading volume from producers, consumers, and financial participants worldwide, making them far more liquid than most spot transactions, which are often private and bilateral.
• Transparency. Futures prices are published continuously by regulated exchanges. True spot prices for physical commodities are frequently negotiated privately and only reported with a lag, if at all.
• Standardization. Every front-month WTI contract is identical. Physical spot deals involve grades, locations, pipeline access, and quality adjustments that make direct comparison difficult. You can learn about those units and conventions in Barrels, Bushels and Troy Ounces: Commodity Units.
• Hedging infrastructure. Producers and commercial buyers use futures to hedge — that is, to lock in prices and reduce the risk of adverse moves. The futures market was built for this purpose, so it naturally becomes the reference price for an entire industry.

Markets That Do Quote True Spot Prices

Not every market hides behind a futures price. Two of the most important exceptions are gold and foreign exchange.

Gold Spot

Gold is primarily quoted as a spot price — specifically, the price per troy ounce (one troy ounce equals approximately 31.1 grams, slightly heavier than a standard ounce) for immediate delivery settled in two business days. The London Bullion Market Association sets a twice-daily benchmark called the LBMA Gold Price, which reflects actual over-the-counter spot trading among large financial institutions. Gold futures exist on the COMEX exchange, but when people quote "the gold price," they almost always mean spot. The guide Gold: Why It Moves and Why It Matters explains the difference in more depth.

Foreign Exchange

The currency market is almost entirely a spot market. When you see a currency pair like EURUSD quoted on any data page, that is the spot exchange rate — the rate at which one currency is exchanged for another for settlement typically within two business days. FX futures exist but are a much smaller slice of overall currency trading volume. The Forex Market: The Complete Guide covers how this enormous, decentralized market operates.

The Relationship Between Spot and Futures Prices

Spot and futures prices for the same commodity are linked but rarely identical. The gap between them reflects several factors that change over time.

When futures prices are higher than the spot price — the most common situation for storable commodities — the market is said to be in contango. When futures prices are lower than spot — often signaling tight current supply — the market is in backwardation. These two states have meaningful implications for anyone holding commodity positions over time, covered in detail in Contango and Backwardation.

How Spot and Futures Converge at Expiry

One of the most reliable mechanics in financial markets is this: as a futures contract approaches its expiration date, its price converges toward the spot price. By the final day of trading, the two are essentially equal.

The logic is straightforward. Suppose a futures contract expires tomorrow and its price is still significantly above the current spot price. A trader could simultaneously buy the commodity in the spot market and sell the futures contract, locking in a near-certain profit — a process called arbitrage. Enough traders doing this pushes the futures price down and the spot price up until the gap closes. Markets are efficient enough that this convergence happens continuously as expiry approaches, not just on the final day.

Suppose a crude oil futures contract expiring in two days is priced at a hypothetical $82 per barrel, while the physical spot price is $80. Arbitrageurs would buy physical oil and sell the futures contract, earning roughly $2 per barrel before transaction costs. That pressure quickly collapses the gap.

This convergence is why the front-month futures price functions as a reliable proxy for the current market value of a commodity, even though no physical oil, grain, or metal has changed hands yet.

What This Means When You Read a Data Table

Understanding the spot-versus-futures distinction helps decode what you are actually looking at on any commodities data page. A few practical points economists and market participants keep in mind:

• The percentage-change columns — day, week, month, year-to-date, year-on-year — show how the front-month futures price has moved over each period. They do not track any single physical contract from start to finish; as one front-month contract expires, the next one takes its place. This "rolling" can introduce small price jumps unrelated to underlying supply and demand.
• When a futures contract rolls from one month to the next, there is often a price jump up or down depending on whether the market is in contango or backwardation. This is called roll yield and it affects the returns of anyone who holds commodity positions over time.
• For currencies and gold, the quoted price is a genuine spot price, so no roll dynamic applies in the same way.
• The price charts you see for most commodities are therefore charts of rolling front-month futures prices stitched together — a continuous series, not one contract's life.

Knowing this does not change what a price means economically — futures and spot track each other closely — but it does help explain occasional data quirks and why comparing a commodity's futures price to a consumer retail price (like gasoline at a pump) always involves additional markups and lags that the exchange price does not capture.
