Commodity Futures: How Oil, Gold, and Wheat Are Traded

Agreements Made Today, Settled Tomorrow

On April 20, 2020, the price of a West Texas Intermediate (WTI) crude oil futures contract fell to negative $37.63 per barrel. Traders were effectively paying buyers to take oil off their hands. The event stunned markets and made headlines worldwide. It also illustrated a fundamental truth about commodity futures: these are not abstract financial instruments. They are legally binding contracts tied to physical goods that must go somewhere.

A commodity futures contract is an agreement to buy or sell a specific quantity of a commodity at a predetermined price on a specified future date. The buyer agrees to take delivery; the seller agrees to deliver. In practice, most contracts are closed before delivery through offsetting trades. But the link to physical commodities distinguishes futures from purely financial instruments.

Anatomy of a Futures Contract

Every futures contract specifies exact terms. There is no ambiguity. The exchange sets the commodity, quantity, quality grade, delivery location, and delivery date. Standardization is what makes these contracts tradeable on exchanges rather than negotiated privately between individual parties.

A single WTI crude oil contract represents 1,000 barrels. At $75 per barrel, that is $75,000 worth of oil per contract. Traders do not need $75,000 to enter the position. They post margin — a performance bond — typically ranging from 5% to 15% of the contract's value. This leverage amplifies both gains and losses.

Hedgers and Speculators

Two types of participants drive commodity futures markets. Hedgers use futures to manage risk. A wheat farmer worried about falling prices before harvest can sell futures contracts to lock in a price today. An airline concerned about rising jet fuel costs can buy crude oil futures. Hedging does not eliminate risk; it transfers it to someone willing to accept it.

Speculators accept that risk in exchange for potential profit. They have no interest in taking delivery of 5,000 bushels of wheat. They trade based on price expectations, providing liquidity that allows hedgers to enter and exit positions efficiently. Without speculators, futures markets would be illiquid and far less useful for risk management.

• Commercial hedgers account for roughly 30-40% of open interest in most commodity markets
• Managed money (hedge funds, commodity trading advisors) represents another 20-30%
• Swap dealers, who intermediate between commercial and financial participants, hold significant positions
• Small speculators (individual traders) make up a relatively small but growing share

The Price Discovery Mechanism

Futures markets serve a critical economic function: price discovery. The price of a futures contract reflects the collective judgment of thousands of participants about future supply and demand conditions. When drought threatens the Midwest, wheat futures rise immediately — long before the reduced harvest reaches market. When OPEC announces production cuts, oil futures adjust within seconds.

This forward-looking pricing ripples through the economy. Airlines set ticket prices partly based on jet fuel futures. Bread manufacturers budget using wheat futures. Mining companies plan expansions around metal futures curves. The prices formed on exchanges in Chicago, New York, and London influence real-world decisions made by businesses that may never trade a single contract.

Contango and Backwardation

The relationship between current (spot) prices and future prices reveals market expectations. When futures prices exceed spot prices, the market is in "contango." This is common when storage costs and financing charges are factored in. When spot prices exceed futures prices, the market is in "backwardation," often signaling tight current supply.

• The negative oil price event of April 2020 resulted from extreme contango combined with near-zero available storage
• Gold typically trades in contango because storage and insurance costs accrue over time
• Agricultural commodities often shift between contango and backwardation seasonally
• Backwardation can indicate that producers are reluctant to sell at current futures prices, expecting supply tightness to persist

How a Futures Trade Executes

Modern futures trading is almost entirely electronic. The CME Group's Globex platform handles over 90% of futures volume. A trader places an order through a broker connected to the exchange. The exchange's matching engine pairs buy and sell orders in microseconds. A clearinghouse — typically the exchange itself — becomes the counterparty to every trade, guaranteeing performance and eliminating counterparty risk between individual traders.

Regulation and Market Oversight

In the United States, the Commodity Futures Trading Commission (CFTC) regulates futures markets. Position limits restrict the number of contracts a single entity can hold to prevent market manipulation. The CFTC publishes the Commitments of Traders (COT) report weekly, disclosing the positions of commercial hedgers, managed money, and other categories. This transparency allows market participants and researchers to assess who is driving price movements.

Market manipulation remains a concern. In 2010, a single trader's massive sell orders in E-mini S&P 500 futures contributed to the Flash Crash, which briefly erased nearly $1 trillion in market value. The incident led to stricter circuit breakers and surveillance protocols.

Physical Delivery and the Real World

Fewer than 3% of futures contracts result in physical delivery. But that small percentage connects the financial market to the physical world. Delivery points for WTI crude oil are in Cushing, Oklahoma. CBOT wheat delivery occurs at approved elevators in Chicago, Toledo, and other Great Lakes locations. Gold delivery involves approved vaults in New York. The logistics are precise, regulated, and surprisingly tangible for markets often perceived as purely digital.

Commodity futures markets have operated for over 170 years since the founding of the Chicago Board of Trade in 1848. They remain essential infrastructure for global commerce, allowing producers, consumers, and intermediaries to manage the uncertainty inherent in physical commodities whose prices depend on weather, geopolitics, and human demand.
