Futures trading means buying or selling a contract that locks in a price today for something you will receive or deliver later

A futures contract is an agreement between two people: one promises to buy something at a set price on a set date in the future, and the other promises to sell it at that same price on that same date. You do not own the thing yet. You are not storing it in a warehouse. You are holding a piece of paper (or more often, a digital record) that says "on December 15, I will pay $5.50 per bushel for 5,000 bushels of corn." The other person holds the matching contract that says "on December 15, I will deliver 5,000 bushels of corn for $5.50 per bushel."

The reason people trade futures is to lock in a price when they are uncertain what that price will be later. A farmer might sell corn futures in July because she wants to know right now what she will earn in December, rather than gamble that prices will be higher or lower by harvest. A cereal company might buy corn futures for the same reason — they want to know their ingredient costs three months ahead. Both sides reduce their risk by agreeing on a price today.

Futures contracts trade on organized exchanges — the Chicago Mercantile Exchange, the New York Mercantile Exchange, and others — not between random individuals. The exchange sets the contract size (how much corn, how much oil, how many dollars), the delivery date, and the quality standards. This standardization is what makes futures liquid: thousands of contracts trade every day, so you can buy or sell quickly without hunting for a matching counterparty.

Key Takeaways

  • A futures contract locks in a price today for delivery of a real commodity or financial instrument at a specific date in the future.
  • Futures are standardized contracts traded on organized exchanges, which means prices are transparent and you can enter or exit a position quickly.
  • Most futures traders never take physical delivery; they close out their contract before the delivery date by selling it to someone else.
  • Futures use leverage, meaning you control a large contract value with a small upfront deposit, which magnifies both gains and losses.
  • Futures prices move based on supply, demand, weather, geopolitics, and other factors that affect the underlying commodity or asset.

How the contract price changes before delivery

The price of a futures contract does not stay fixed at what you agreed to on day one. The contract itself — the obligation to buy or sell at that price — trades like a stock. If corn prices rise between July and December, a corn futures contract you bought in July becomes more valuable, because you locked in a lower price than the market now offers. You can sell that contract to someone else for a profit. If corn prices fall, your contract becomes less valuable, and you take a loss if you sell.

This is where most futures trading happens: people buying and selling the contracts themselves, not the corn. A trader might buy a December corn contract on Monday, sell it on Wednesday, and never touch a kernel of corn in their life. The farmer and the cereal company are using futures to hedge — to reduce risk. The trader is using futures to speculate — to profit from price movements. Both are necessary for the market to function.

Leverage and margin in futures trading

Futures use leverage, which means you control a large contract value with a small upfront payment called margin. A corn futures contract represents 5,000 bushels. At $5 per bushel, that is $25,000 of value. But you do not need $25,000 to buy that contract. Your broker might require only $1,500 upfront — the margin. The rest is borrowed.

Leverage cuts both ways. If corn rises to $5.50 per bushel, your $25,000 contract is now worth $27,500 — a $2,500 gain on your $1,500 investment, or roughly 167 percent. But if corn falls to $4.50 per bushel, your contract is worth $22,500 — a $2,500 loss that wipes out your entire margin and leaves you owing money. This is why futures are riskier than buying the commodity outright: you can lose more than you invested.

Your broker monitors your margin balance daily. If losses shrink your margin below a certain threshold, the broker issues a margin call and demands you deposit more money or close the position. This forces you to act quickly, sometimes at unfavorable prices.

Physical delivery versus closing out the contract

When a futures contract reaches its delivery date, the person holding the contract to sell must deliver the commodity (or cash equivalent, depending on the contract), and the person holding the contract to buy must accept it and pay. But this almost never happens in practice. Instead, traders close out their positions before delivery by selling their contract to someone else.

If you bought a December corn contract in July, you can sell that same contract in November to a different trader. You never owned corn, and you never will. The new owner now holds the contract and must decide whether to take delivery in December or sell it to someone else before then. Most contracts expire without physical delivery ever occurring.

Some futures contracts — particularly financial futures like stock index futures or Treasury futures — are cash-settled. There is no physical delivery at all. The contract straightforward pays out the difference between the locked-in price and the market price on the delivery date, and the contract ends.

What moves futures prices

Futures prices reflect what traders believe the commodity or asset will be worth at delivery. A drought in the Midwest will push corn futures higher because traders expect a smaller harvest and higher prices later. A report that oil inventories are rising will push crude oil futures lower. A central bank interest rate decision will move Treasury futures. Geopolitical events, weather, economic data, and supply disruptions all flow into futures prices in real time.

Futures prices also tend to move toward the spot price — the price you would pay to buy the commodity right now in the physical market. If December corn futures are trading at $5.50 but you can buy corn today for $5.00, traders will buy spot corn and sell December futures, pocketing the difference. This arbitrage keeps futures prices tethered to reality.

Who trades futures and why

Hedgers are producers or consumers of the underlying commodity. A wheat farmer sells wheat futures to lock in revenue. An airline buys jet fuel futures to lock in fuel costs. A pension fund buys Treasury futures to manage interest rate risk. These traders use futures to reduce uncertainty about future prices.

Speculators are traders who do not produce or consume the commodity. They buy and sell futures contracts to profit from price movements. Some speculators are individuals trading through a retail broker. Others are professional traders at hedge funds or proprietary trading firms. Speculators provide liquidity — they are willing to take the other side of a hedger's trade — but they also add volatility because they respond quickly to news and sentiment.

Arbitrageurs exploit price differences between related markets. They might buy corn futures and sell corn options, or buy crude oil futures and sell refined product futures, capturing small but reliable profits from temporary mispricings.

Risks specific to futures trading

Futures are leveraged, which means losses can exceed your initial investment. You can lose your margin and owe money to your broker. Futures markets can gap — jump sharply between trades — leaving you unable to exit at the price you expected. Liquidity can dry up near delivery dates or during market stress, making it hard to close a position. Margin calls can force you to liquidate at the worst time. And futures prices can move violently on news or data releases, wiping out positions in minutes.

Futures are also standardized contracts, which means you cannot customize the size, date, or terms to match your exact needs. If you need to hedge 3,500 bushels of corn but contracts are 5,000 bushels, you either over-hedge or under-hedge. This inflexibility is the trade-off for the liquidity and transparency that standardization provides.

Frequently Asked Questions

Do I have to take physical delivery if I hold a futures contract to the end?

Almost no one does. Traders close out their contracts before delivery by selling them to someone else. If you do hold a contract to expiration, your broker will typically cash-settle it or force you to close it. Physical delivery is rare and usually only happens when a hedger actually needs the commodity.

Can I lose more money than I put in with futures?

Yes. Leverage means you control a large position with a small deposit. If the price moves sharply against you, losses can exceed your margin. Your broker may issue a margin call demanding more money, or liquidate your position to cover losses. In extreme cases, you can owe money after the position is closed.

What is the difference between futures and options?

A futures contract is an obligation to buy or sell at a set price. An options contract is the right, but not the obligation, to buy or sell. With futures, both sides must perform at delivery. With options, the buyer can choose to walk away. Options have a lower upfront cost but expire worthless if the price does not move in your favor.

How much money do I need to start trading futures?

Margin requirements vary by contract and broker, but typically range from $500 to $5,000 per contract. This is not the full contract value — it is the deposit your broker requires to hold the position. You should have additional cash available for margin calls and to cover potential losses.

Why do futures prices sometimes go negative?

Futures prices reflect supply and demand for future delivery. If storage costs are high and demand collapses, the price of a near-delivery contract can fall below zero — meaning sellers will pay buyers to take the contract off their hands. This happened to crude oil futures in April 2020 when storage was full and demand had crashed.
