Key Takeaways
Direct answer: A futures contract is a standardized, exchange-traded agreement obligating the buyer to purchase, and the seller to sell, a specific quantity of an underlying asset at a fixed price on a fixed future date, or to exchange the equivalent cash value. Both sides are obligated, not merely permitted, to complete the transaction, and the exchange's clearinghouse becomes the legal counterparty to both once a trade is matched.
- Every futures contract has two sides: a long, who profits if the price rises, and a short, who profits if the price falls.
- Contracts are standardized by the exchange. Traders only negotiate price and the number of contracts, not the underlying, size, or settlement terms.
- A clearinghouse becomes the counterparty to every matched trade, removing direct counterparty risk between the original buyer and seller.
- Most positions are closed, offset, or rolled before expiration rather than carried through to physical delivery.
- Participants fall into two broad categories: hedgers managing existing business exposure, and speculators taking on price risk deliberately.
A Futures Contract, Defined Precisely
A futures contract fixes four things at the moment it is traded: the underlying asset, the quantity, the price, and the future date on which the transaction settles. Everything else, the underlying's exact specification, the contract size, the settlement method, and the calendar of available expiration months, is standardized in advance by the listing exchange. This is what makes a futures contract different from an informal agreement between two parties to trade something later: two traders anywhere in the world can transact on a shared, exchange-defined contract without negotiating its terms from scratch.
Once a buy order and a sell order are matched on the exchange, the exchange's clearinghouse legally interposes itself between the two sides, a process called novation. The original buyer's contract is now with the clearinghouse, and so is the original seller's. Neither party depends on the other's creditworthiness going forward; both depend on the clearinghouse, which manages that risk through the margin system covered on Swoopr's Futures Margin page.
Long and Short: The Two Sides of Every Contract
A trader who is long a futures contract has agreed to buy the underlying at the contract price on the settlement date, and the position gains value as the contract's price rises. A trader who is short has agreed to sell at that price, and the position gains value as the contract's price falls. Because every futures trade is created by matching a buyer and a seller in equal size, going short in futures requires no separate borrowing step the way short-selling a stock does; it is simply the other side of the same contract.
Both the long and the short are obligated to complete the transaction, or to close the position before it comes due. This is the core distinction between a futures contract and an option: an option buyer has a right without an obligation to exercise it, while both sides of a futures contract are committed unless the position is closed, offset, or expires by its settlement terms.
A Position's Lifecycle: Open, Mark, Close
A futures position moves through three stages. First, opening: an order is placed and matched, creating a long position for the buyer and a short position for an equal number of contracts on the seller's side, with initial margin posted to the broker. Second, holding: while the position stays open, it is marked to market at the end of each trading day, with gains and losses settled in cash into or out of the account, a mechanic Swoopr's Futures hub covers under daily settlement. Third, closing: the position ends either by an offsetting trade before the last trading day, most commonly, or by the contract reaching its settlement date and resolving through physical delivery or cash settlement according to its specification.
An offsetting trade is simply the opposite transaction in the same contract: a long position is closed by selling the same contract and month, a short position by buying it back. The trader does not need to find the original counterparty; the exchange and clearinghouse net the positions automatically.
Vocabulary: Contract Month, Tick, Open Interest, Volume
| Term | Meaning |
|---|---|
| Contract month | The specific calendar month in which a listed contract expires or settles; a given underlying typically has several contract months listed at once |
| Tick | The smallest allowed price increment for the contract, set by the exchange |
| Notional value | The contract's multiplier times its current price; the real dollar exposure one contract represents |
| Volume | The number of contracts that changed hands in a given period, such as a trading day |
| Open interest | The total number of contracts in a given contract month that remain open, neither closed nor settled, as of a point in time |
| Front month | The nearest contract month currently trading; often, though not always, the most liquid |
Volume and open interest answer different questions. High volume with flat open interest suggests traders are largely offsetting existing positions rather than establishing new ones; rising open interest alongside rising volume suggests new money is entering the contract. Neither figure predicts price direction on its own.
Who Trades Futures, and Why
The CFTC's regulatory framework for futures markets separates participants into two broad categories. A hedger already has, or expects to have, exposure to the underlying asset through the ordinary course of a business, a wheat farmer locking in a future sale price, an airline hedging jet-fuel costs, a manufacturer hedging a foreign-currency payable, and uses a futures position to reduce the risk of an adverse price move against that existing exposure. A speculator has no offsetting business exposure to the underlying and takes on price risk on purpose, aiming to profit from an anticipated move.
An individual investor trading futures for portfolio, tactical, or income reasons is a speculator under this framework, even if the position is described informally as a hedge against a stock portfolio. That distinction matters because exchanges and the CFTC apply different position-limit and reporting treatment to genuine commercial hedging than to speculative positions, and because a speculator, unlike a hedger, has no offsetting business cash flow to absorb a loss on the futures position itself.
Why Futures Markets Exist
Futures markets exist to serve two economic functions: price discovery, aggregating many participants' expectations about a future price into a single, continuously updated number, and risk transfer, letting a party who does not want price risk (a hedger) shift it to a party willing to accept it in exchange for potential profit (a speculator). Neither function requires most participants to ever exchange the physical underlying; the price and risk-transfer functions work through the contract itself, which is why the CFTC's own materials note that most contracts are liquidated before delivery rather than carried to it.
Common Mistakes
- Assuming a futures position can simply be abandoned like an unexercised option; both sides are obligated unless the position is closed, offset, or the contract's terms otherwise resolve it.
- Confusing volume with open interest, or treating either as a directional price signal on its own.
- Assuming "hedging" a stock portfolio with an index future makes the position risk-free; a speculative futures position still carries its own margin, mark-to-market, and expiration risk.
- Not knowing which contract month a position is actually in, and being surprised when a front-month contract approaches its last trading day.
Frequently Asked Questions
What does it mean to go long or short a futures contract?
Going long means agreeing to buy the underlying asset at the contract's price on the settlement date, and it profits if the price rises. Going short means agreeing to sell at that price, and it profits if the price falls. Unlike buying a stock, opening a short futures position requires no separate borrowing step; it is simply the other side of the same standardized contract.
Do I need to own the underlying asset to trade a futures contract?
No. A futures contract is an agreement about a future transaction, not a transfer of the underlying asset today. Most individual traders never intend to make or take delivery; they close, offset, or roll the position before the contract's last trading day.
What is open interest, and why does it matter?
Open interest is the total number of futures contracts in a given contract month that remain open, neither closed out nor settled. It is a measure of how much capital and how many participants are committed to that contract, distinct from trading volume, which measures how many contracts changed hands in a given period.
Who actually trades futures contracts?
The CFTC's regulatory framework groups participants into hedgers, who already have or expect exposure to the underlying asset in their business and use futures to manage that risk, and speculators, who take on price risk deliberately without an offsetting business exposure, seeking to profit from anticipated price moves. An individual investor trading futures for portfolio or tactical reasons is a speculator in this framework.
What is the difference between volume and open interest on the same contract?
Volume counts contracts traded during the period, and it resets each session. Open interest counts contracts that remain open at the end of the period, and it carries forward. A single contract can be bought and sold repeatedly in one day, lifting volume without changing open interest at all. Open interest rises only when a new long and a new short are created together, and falls when both sides of an existing contract close.
Does the futures price predict the future spot price?
A futures price is what participants will transact at today for a later date, not a forecast that the market is committing to. It embeds financing costs, storage where the underlying is physical, and the balance of hedging demand, so it can sit above or below the current spot price for reasons that have nothing to do with an expected move. Treating the curve as a prediction confuses the price of deferred delivery with an opinion about where spot will settle.
What happens to a futures position if the trader does nothing before the last trading day?
The contract resolves on its own terms rather than expiring worthless. A cash-settled contract is closed against the final settlement price the exchange publishes, and the resulting gain or loss is booked to the account. A physically deliverable contract moves into the exchange delivery process, which is why brokers commonly restrict or liquidate deliverable positions held by non-commercial accounts as the delivery period approaches. Neither outcome is optional the way abandoning an out-of-the-money option is.
Why is there no borrowing step when going short a futures contract?
Selling short a stock requires locating and borrowing shares, because the seller must deliver something that already exists. A futures contract is created at the moment a buyer and a seller agree, so the short side is originated rather than borrowed. There is nothing to locate and no borrow fee or recall risk. That is why short exposure in futures is symmetric with long exposure in a way that stock short selling is not.
What is the difference between a futures contract and a forward contract?
Both fix a price today for a transaction later, but a futures contract is standardized by an exchange, cleared through a clearinghouse and marked to market in cash every day. A forward is negotiated privately between two parties, so its size, date and terms can be tailored, and it usually settles only once at maturity. The tradeoff is credit exposure: each side of a forward relies on the other to perform, while a cleared future substitutes the clearinghouse for that risk.
Is a futures contract a security?
Most futures are regulated as commodity interests under the Commodity Exchange Act and the CFTC rather than as securities under the federal securities laws. The practical consequences are real: the account protections, margin rules and disclosure regime differ from those attached to stocks. Security futures, which reference a single stock or a narrow index, sit in a joint regime overseen by both regulators, which is why their rules do not match either category cleanly.
