A futures contract is a standardized, legally binding agreement between two parties to buy or sell an underlying asset at a fixed price on a specific date in the future.
When commodity prices shift, businesses and investors need a reliable way to manage exposure. Futures markets provide that stability by establishing contract terms today for transactions that take place down the road. This explainer covers how futures contracts work, how margins operate, and how they connect to the broader macro economy.
Quick Takeaways4 takeaways
A futures contract obligates both the long (buyer) and short (seller) positions to fulfill terms at expiration, unlike an option which grants the right without the obligation.
Standardization by centralized exchanges ensures contract sizes, tick values, and expiration dates remain uniform for seamless market liquidity.
Daily mark-to-market accounting settles gains and losses in cash each trading day, directly impacting margin balances.
Hedgers use futures to lock in future transaction prices, while speculators provide liquidity to capture price movements.
How a Futures Contract Works: Mechanics and Standardization
What is a futures contract in practice? It comes down to how it standardizes the exchange of physical goods or financial assets. Unlike over-the-counter forward contracts—which are customized private deals—futures trade on organized public exchanges.
To ensure every market participant trades identical instruments, exchanges establish rigid specifications:
Contract Size: Defines the exact quantity of the underlying asset per contract — for example, 1,000 barrels for a NYMEX crude oil futures contract or 5,000 bushels of corn).
Tick Size: Sets the minimum allowable price movement and its corresponding cash value.
Delivery Dates: Establishes standardized monthly or quarterly settlement schedules.
Quality Grade: Defines the physical standards for delivered commodities, such as specific gravity and sulfur content for crude oil.

The exchange clearinghouse acts as the central counterparty to every transaction. Once a trade matches, the clearinghouse becomes the buyer to every seller and the seller to every buyer. This process guarantees contractual performance and minimizes counterparty default risk.
This process guarantees contractual performance and minimizes counterparty default risk for both the long position (the buyer) and the short position (the seller).
Margin and Daily Settlement: Managing Derivative Leverage
Trading futures does not require paying the full cash value of the underlying asset up front. Instead, market participants deposit a cash performance bond known as margin.
Initial Margin: The baseline equity required by the broker to open a futures position.
Maintenance Margin: The minimum balance that must remain in the account at all times to keep the position active.
Because margin represents only a fraction of the total contract value—commonly cited as roughly 3% to 12% of notional value depending on the exchange and product, according to exchange margin guidelines such as CME Group's—futures provide capital leverage. Leverage magnifies both capital gains and trading losses.
Futures accounts use daily mark-to-market accounting. At the end of every trading session, the exchange calculates gains and losses by comparing the current settlement price against the previous day's price. Profit is credited directly to the trader's account in cash, while losses are immediately debited.
If market movements push an account balance below the maintenance margin threshold, the broker issues a margin call. The trader must immediately deposit additional funds to restore the account to the initial margin level or face involuntary position liquidation.
Physical Delivery vs. Cash Settlement
Futures contracts settle at expiration in one of two primary ways: physical delivery or cash settlement.
Settlement Type
How It Works
Common Examples
Physical Settlement
At expiration, eligible long and short positions are obligated to take or make delivery according to the contract’s specifications. Delivery may occur through warehouse receipts, shipping certificates, pipeline arrangements, or other exchange-approved mechanisms.
Physical commodity futures such as crude oil, wheat, and gold, as well as certain government bond futures.
Cash Settlement
No physical asset changes hands. The contract is settled in cash based on the exchange-defined final settlement price or reference benchmark.
Equity index futures, volatility futures, and certain interest-rate futures.
In practice, many futures positions are closed or rolled before expiration, particularly when traders do not intend to make or take physical delivery. Traders can offset an open position by entering an opposite transaction in the same contract—for example, buying to close an existing short position or selling to close an existing long position.
Tip: Futures traders should size positions based on the contract’s notional exposure and potential price volatility, not simply on the initial margin required to open the trade. Because futures are marked to market daily, adverse price moves can generate variation-margin obligations that require additional cash even when the initial margin represents only a fraction of the contract’s value. Maintaining adequate liquidity and monitoring margin requirements can reduce the risk of being forced to close positions during periods of sharp market volatility.
Hedgers vs. Speculators: Who Uses Futures?
Participants in the futures market fall into two main categories: hedgers and speculators.
Comparison of hedgers and speculators showing their roles in futures market risk and liquidity.
Hedgers (Risk Mitigation)
Commercial producers and corporate buyers use futures to transfer price risk. A wheat farmer sells futures to lock in crop prices months before harvest, protecting against market declines. An airline buys jet fuel futures to fix energy costs, guarding against sudden price spikes. Hedgers focus on operational predictability rather than market speculation.
Speculators (Liquidity Providers)
Speculators trade futures solely to profit from price changes. They assume the price risk that hedgers want to avoid. By frequently entering long and short positions, speculators provide essential market depth, narrow bid-ask spreads, and ensure commercial hedgers can execute transactions efficiently.
How Commodity Futures Connect to the Broader Macro Economy

Futures pricing extends beyond exchange floors to influence broader macroeconomic conditions. Because futures trade continuously across future delivery months, they act as an ongoing price discovery mechanism for global markets.
The relationship between immediate spot prices and deferred futures prices creates a term structure:
Contango: Occurs when futures prices trade higher than current spot prices. This upward slope reflects storage costs, insurance, financing costs, and physical holding expenses over time.
Backwardation: Occurs when spot prices trade higher than deferred futures prices. This pattern points to immediate supply shortages, high current demand, or structural market stress.
Changes in futures prices directly impact everyday consumer costs. When global energy futures rise, refiners face higher input expenses, driving up retail gas prices and transportation overhead. Because raw material costs filter through global supply chains with a lag, monitoring futures pricing can offer useful signals that may help indicate emerging inflation trends.
Common Beginner Pitfalls in Futures Trading
Trading standardized derivative products introduces unique risks that differ from spot equity investing:
Confusing Margin with Capital Costs: Treating margin as a simple deposit obscures total contract exposure. A slight adverse price move in a leveraged contract can wipe out the initial deposit entirely.
Ignoring Expiration Dates and Roll Risk: Traders holding physical-delivery contracts past the last trading day risk unexpected delivery obligations. Position rollover requires closing expiring contracts and re-establishing them in later months, which incurs transaction fees and spread costs.
Failing to Reserve Buffer Cash: Relying on precise maintenance margins leaves zero room for daily mark-to-market swings, leading to quick broker liquidations during intraday volatility.
What Is a Futures Contract? Key Takeaways
A futures contract serves as a foundational building block in global finance, binding buyers and sellers to transparent prices for future delivery. By centralizing risk transfer through standardized exchange clearing, futures grant commercial businesses a tool to lock in operational costs while offering investors capital efficiency.
Understanding daily settlement, performance margin, and market term structures allows investors to evaluate market expectations across the broader commodity space. Derivative markets always carry the risk of financial loss due to leverage, so treat these mechanics as educational context for evaluating market risk.
FAQ
How do futures contracts differ from options contracts?
Now that you know what is a futures contract, it's worth comparing it to options: a futures contract obligates both the buyer and seller to fulfill the terms at expiration. An option contract grants the buyer the right, but not the obligation, to execute the transaction, while the option seller retains the obligation if exercised.
What happens when a futures contract expires?
At expiration, a futures contract is settled via physical delivery of the underlying commodity or through cash settlement based on the final benchmark index price. However, most market participants close out or roll their positions before expiration.
What is daily mark-to-market settlement in futures trading?
Daily mark-to-market settlement is an accounting process where the exchange calculates position gains and losses at the end of each trading day. Cash profits are credited directly to the trader's account, while losses are debited immediately from account margins.
Can you lose more money than your initial margin deposit in futures?
Yes. Because futures use capital leverage based on full contract value rather than deposit size, severe market gaps or rapid adverse price movements can result in losses that exceed the initial margin deposit.
Why do commercial businesses use commodity futures?
Commercial producers and corporate buyers use futures as hedging instruments to lock in purchase or sale prices months in advance, protecting their business operations from unexpected commodity price volatility.
