What Is a Futures Contract? How Commodity Futures Work

Written by Jim Norris · NorrisAI AlphaLens · Updated August 2026

Quick answer: A futures contract is a legally binding agreement to buy or sell a specific asset — a commodity, currency, index, or interest rate — at a predetermined price on a specific future date. Futures are used by producers to lock in prices (hedging) and by investors to speculate on price direction or gain exposure to assets without owning them directly. For equity investors, futures prices on commodities and rates provide real-time signals about supply, demand, and market expectations.

How futures contracts work

Two parties enter a futures contract:

The long side agrees to buy the underlying asset at the contract price on the delivery date. They profit if prices rise above the contract price.

The short side agrees to sell the underlying asset at the contract price on the delivery date. They profit if prices fall below the contract price.

Futures trade on exchanges (CME, ICE, NYMEX) with standardized contract sizes and delivery terms. Most futures positions are closed before delivery — the parties settle the price difference in cash rather than exchanging physical barrels of oil or bushels of wheat.

Margin requirements: futures traders post a fraction of the contract value as collateral (initial margin). This leverage amplifies both gains and losses dramatically — a key risk distinction from owning the underlying commodity directly.

Who uses futures and why

Producers: an oil company expecting to produce 1 million barrels in 6 months sells futures at today's price, locking in revenue regardless of where prices move. This is hedging — reducing price uncertainty.

Consumers: an airline needing jet fuel buys futures to lock in costs, protecting against oil price spikes. The same hedging logic from the buyer's side.

Speculators: traders who have no underlying commodity exposure use futures to bet on price direction. They provide market liquidity but accept the price risk that hedgers want to shed.

Index investors: commodity ETFs often use futures rather than holding physical commodities — creating "roll yield" costs as contracts expire and must be replaced by new ones.

What futures prices signal for stock investors

Oil futures affect energy stocks, airline cost structures, consumer spending power, and inflation expectations. Contango (future prices above spot) suggests oversupply; backwardation (future prices below spot) suggests tight supply.

Agricultural futures affect food companies' input costs and consumer staples margins. Rising corn and wheat futures pressure food manufacturers who can't immediately pass costs to consumers.

Metal futures (copper especially) are economic leading indicators — copper demand tracks industrial production closely. A rising copper price often signals global economic strength; falling copper is called "Dr. Copper's recession warning."

Interest rate futures embed market expectations for Fed policy — they're often more accurate than Fed surveys for predicting near-term rate moves.

Howard Marks has noted that futures markets are among the most efficient in the world — they aggregate the collective knowledge and expectations of sophisticated producers, consumers, and financial participants. When futures prices diverge significantly from spot prices, the market is embedding specific expectations about future supply and demand worth understanding.

How AlphaLens uses commodity futures context

The Macro Sensitivity Analysis (framework #13) evaluates how specific stocks are affected by commodity price movements — identifying which holdings have significant exposure to oil, metals, agricultural inputs, or other futures-priced commodities. The Full Company Breakdown establishes whether a company is a commodity producer (benefits from rising prices), consumer (hurt by rising prices), or insulated (can pass costs through with pricing power).
