What Are Futures?

Introduction

Long before options, ETFs or shares as we know them, there were futures. A farmer in the 19th century, months from harvest, had no idea what price his wheat would fetch. A miller who needed that wheat faced the same uncertainty in reverse. So they struck a deal in advance: a fixed price, for a fixed quantity, delivered on a fixed date. Both sides swapped uncertainty for certainty. That simple bargain is the futures contract, and it still works exactly the same way today — only now the "wheat" might be the S&P 500, a barrel of oil or an ounce of gold.

Futures are the purest expression of a derivative: an instrument whose value derives from something else. They power global markets in commodities, indices, currencies and rates, they trade nearly around the clock, and they offer enormous leverage — which makes them both a precise risk-management tool and one of the fastest ways to blow up an account. This article explains what a futures contract really is, how it works, and why it matters, before the rest of this category dives into the details.

Quick Definition

A futures contract is a standardised, legally binding agreement to buy or sell a specific quantity of an asset at an agreed price on a specified future date. Both parties are obligated to fulfil it — the buyer to take delivery (or its cash equivalent), the seller to deliver.

The word to hold onto is obligation. This is what separates futures from options, and it shapes everything about their risk.

Born To Manage Risk

Futures exist to solve a real problem: price uncertainty about the future. Picture two people:

• A wheat farmer fears prices will fall by harvest, leaving him with less than his costs.
• A bread maker fears prices will rise, squeezing her margins.

By agreeing a price now for delivery at harvest, both remove the uncertainty. If prices later fall, the farmer is protected; if they rise, the baker is protected. Neither is speculating — each is hedging, trading away a risk they don't want. This is the beating heart of the futures market, and it's why the market is dominated by real-world producers and users of everything from oil to interest rates. Everyone else — the speculators — exists largely to take the other side of those hedges.

Anatomy Of A Standardised Contract

A private handshake deal is hard to trade. The genius of modern futures is standardisation: exchanges define every term except the price, so contracts become interchangeable and liquid.

Each contract fixes: the underlying (what's being traded), the contract size (how much — e.g. 1,000 barrels of oil), the expiry (when it settles), the tick size (the smallest price increment), and the settlement method (physical delivery or cash). The full detail of these terms is covered in Contract Specifications.

Long, Short — And Obligation

You can take either side of a future:

• Go long (buy) if you expect the price to rise. You're obligated to buy at the agreed price.
• Go short (sell) if you expect the price to fall. You're obligated to sell at the agreed price.

Futures are perfectly symmetric — going short is as natural as going long, with no borrowing required, which is one reason traders use them to bet on falling markets. But note the word again: obligation. Unlike an option holder, who can simply walk away and lose only the premium, a futures trader is on the hook for the full move against them until they close the position. That symmetry of obligation is the source of both futures' usefulness and their danger.

Leverage: The Double-Edged Sword

Here is what makes futures so potent. You don't pay the full value of the contract — you post a margin, a good-faith deposit that's often just 5–10% of the contract's notional value. That means a small amount of capital controls a large position.

Leverage is neutral in theory and lethal in practice for the unprepared. A 2% move in the underlying — routine in a single day — can mean a 40% swing on your deposit. Win, and the returns are extraordinary; lose, and you can lose your entire margin and be asked for more (a margin call). Because the mechanics of margin are so central, they get their own article: Margin Requirements.

Hedgers And Speculators

Every futures market has two tribes, and it needs both:

• Hedgers use futures to reduce risk they already face: an airline locking in fuel costs, a farmer fixing a crop price, a fund manager protecting a portfolio against a market fall. For them, futures are insurance.
• Speculators take on risk hoping to profit from price moves. They rarely want the physical wheat or oil; they want the price change. In doing so they provide the liquidity and take the other side of the hedgers' trades.

This partnership is the market's engine. Without speculators, hedgers would struggle to find counterparties; without hedgers, there'd be less real-world reason for the market to exist. Neither is villain or hero — both are necessary.

Mark-To-Market: Settling Every Day

One feature makes futures unusual: they are marked to market daily. Rather than waiting until expiry to settle up, the exchange tallies each contract's gain or loss every single day, moving money between the winners' and losers' margin accounts. If the market moves against you, cash leaves your account that night; if your margin runs too low, you get a margin call. This daily settlement — explored in Futures Settlement — is what keeps the system solvent and prevents losses from piling up unseen until it's too late.

Futures vs Options vs Shares

It helps to place futures alongside their cousins:

• Shares give you ownership, no expiry, and losses limited to what you invested. Simple and unleveraged (unless you add margin).
• Options give you a right, not an obligation, for a premium you can lose but never exceed — asymmetric risk.
• Futures give you a symmetric obligation, with heavy leverage and daily settlement — the biggest exposure per pound, and the biggest responsibility.

None is "best"; each suits different jobs. Futures excel at efficient, leveraged, two-way exposure to indices and commodities — and at hedging — but they demand the most discipline.

Common Misconceptions

"Futures are just for commodities." No — the most heavily traded futures track stock indices (like the S&P 500), interest rates and currencies. Commodities are only one corner.

"Futures and options are the same." They're both derivatives, but the difference is fundamental: options are a right; futures are an obligation. Your maximum loss profile is completely different.

"Leverage means bigger returns." It means bigger outcomes — in both directions. Leverage magnifies losses exactly as much as gains, and can cost you more than your deposit.

"You have to take delivery of the oil." Almost never. The vast majority of speculative positions are closed before expiry, and many contracts settle in cash rather than physical delivery.

Real-World Application

Imagine a fund manager holding a £1,000,000 UK share portfolio who fears a short-term market drop but doesn't want to sell (and trigger costs and taxes). Instead, she shorts stock-index futures worth roughly £1,000,000. If the market falls 5%, her portfolio loses about £50,000 — but her short futures position gains about £50,000, cancelling the loss. She has hedged, using futures exactly as the 19th-century farmer did, swapping uncertainty for protection. When her worry passes, she closes the futures and carries on holding her shares.

Now contrast a speculator who, with £5,000 of margin, goes long an index future worth £100,000 hoping for a rally. A 3% rise hands him roughly £3,000 — a 60% return on his margin in days. But a 3% fall costs him £3,000, more than half his deposit, and a sharper drop could wipe him out and leave him owing more. Same instrument, opposite spirit: one is buying insurance, the other is amplifying a bet. Understanding which you are doing — and respecting the leverage — is the whole game.

Key Takeaways

• A futures contract is a standardised, binding agreement to buy or sell an asset at a set price on a set date — an obligation for both sides.
• Futures were born to hedge real-world price risk, and hedging remains their core purpose.
• Standardisation (fixed underlying, size, expiry, tick, settlement) makes them liquid; only price is negotiated.
• Leverage via margin magnifies gains and losses alike — a small move can swing your deposit dramatically and trigger a margin call.
• Markets need both hedgers (reducing risk) and speculators (taking it on for profit and liquidity).
• Futures differ from options (a right, not an obligation) and shares (ownership, no leverage or expiry) — powerful, but demanding the most discipline.
