Futures Contract

A futures contract is a standardized, exchange-traded agreement to buy or sell a specified underlying exposure at a stated price for settlement in a future contract month. The exchange defines the contract unit, eligible delivery or cash-settlement terms, price increment, trading hours, and expiration rules. A clearing organization generally stands between buyers and sellers, while gains and losses are settled through margin accounts.

The standard industry term is futures contract, not “future contract.” A futures transaction is simply a purchase or sale of one of these contracts, not a separate instrument.

Key Takeaways

• A long futures position benefits when the futures price rises; a short position benefits when it falls.
• Futures margin is a performance bond, not a down payment on the underlying asset.
• Open positions are marked to market, so losses can require cash before the contract expires.
• Most positions are closed by an offsetting trade, but the contract’s delivery or cash-settlement rules still matter.
• Standardization and clearing can improve liquidity and reduce bilateral credit exposure, but they do not eliminate market, basis, margin, operational, or default risk.
• Notional, tick value, margin, and cash at risk are different measures and should not be used interchangeably.
• The exchange’s current rulebook and the broker’s account terms control actual obligations and deadlines.

How the Futures Market Is Organized

A futures market is the exchange, clearing, brokerage, and market-data system through which standardized futures contracts are traded and settled. The exchange lists the contract and operates or authorizes the trading venue. After a trade is matched, a clearing organization becomes the central counterparty under its rules, and clearing members manage obligations to the clearing system.

The diagram is a simplified customer workflow. Direct clearing participants, proprietary firms, market makers, and other account structures can follow different operational paths. The contractual and money flows should be verified from the exchange, clearing, broker, and account records.

Futures markets are centralized around standard contracts, but liquidity is not uniform. A heavily traded nearby contract can have a narrow spread while a deferred or specialty contract has little depth. Exchange trading and clearing also do not guarantee an exit at a chosen price.

Contract Terms to Read

Never infer a futures exposure from the product name alone. Check the exchange’s current contract specifications for:

• underlying commodity, instrument, rate, currency, or index;
• contract unit and price multiplier;
• quote format and minimum tick;
• listed contract months and last trading day;
• daily and final settlement procedures;
• physical-delivery grade, location, and notice rules, if applicable;
• position limits or accountability levels; and
• initial, maintenance, and any additional broker margin requirements.

Contract specifications can change. The exchange rulebook and clearing or broker records control the actual position.

Notional Value, Tick Value, and Position Sensitivity

For a contract quoted as money per unit of an underlying asset, a simplified notional calculation is:

For an index-quoted contract, notional is commonly the index level multiplied by a money multiplier. Other products can use rate, bond-price, or contract-specific conventions.

The value of one minimum price movement is:

Assume a hypothetical contract represents 1,000 units, trades at $50.00 per unit, and has a minimum price increment of $0.01.

A margin deposit of $20,000 for the position would not change the $400,000 notional. Margin supports performance; it does not replace the exposure calculation or cap the loss.

All figures are invented for instruction. Current contract specifications and broker margin requirements control an actual position.

Long and Short Futures

The long buys the contract and gains when its settlement price rises. The short sells the contract and gains when its settlement price falls.

For n contracts, each representing Q units, the long’s daily variation gain or loss is:

where F_t is today’s settlement price and F_{t-1} is the previous settlement price. The short has the opposite result. Some financial contracts quote an index or rate and use a monetary multiplier rather than a physical unit; use the specification for that contract.

Practical Example: Daily Mark-to-Market

Assume a trader is long 2 futures contracts, each representing 100 units. The settlement price rises from $50 to $52.

The long account receives a $400 daily variation gain and the short side incurs the corresponding loss, before commissions and other costs. If the price instead fell to $47, the long’s daily loss would be $600.

The contract’s notional exposure at the original $50 price is 2 x 100 x $50 = $10,000. That is not the amount deposited as margin and is not a maximum-loss measure. The daily cash credit or debit occurs even though the trader has not offset the position.

Worked Example: Multi-Day Settlement Ledger

Assume one long contract represents 100 units. The trader enters at $50.00, and the following daily settlement prices apply:

The cumulative result equals the entry-to-exit change:

The path still matters. The trader receives and pays cash during the holding period, and a sufficiently large interim loss can trigger a margin call or liquidation before a later recovery occurs.

Contract Lifecycle

A futures position generally moves through these stages:

1. Select the contract: Identify the exact product, month, unit, quote, and settlement rules.
2. Enter an order: Specify buy or sell, quantity, order type, and contract code.
3. Trade and clear: The order matches on the venue and the resulting obligation enters the clearing system.
4. Post margin: The account maintains collateral under exchange, clearing, and broker requirements.
5. Settle daily: Gains and losses are credited or debited using the applicable settlement process.
6. Manage the position: Monitor exposure, limits, liquidity, basis, collateral, and upcoming deadlines.
7. Exit or settle: Offset, roll, cash settle, or complete physical delivery under the rules.

The original buyer and seller do not need to find each other again to exit. A trader can normally offset in the same contract through the market. Liquidity, price limits, account restrictions, or disruption can still prevent an exit at the intended time or price.

How Futures Margin Works

Futures margin supports contract performance:

1. Initial margin: Funds or eligible collateral required to open or carry the position.
2. Maintenance margin: The minimum account equity required before additional funds may be demanded.
3. Variation settlement: Daily, and sometimes intraday, credits and debits caused by price changes.
4. Margin call: A demand for additional funds after losses or a margin-requirement increase.

Exchange minimums can change with volatility, and a futures commission merchant may require more than the exchange minimum. A hedged position can still produce a margin call even if a related cash-market exposure has gained value but has not generated cash.

Margin Is Not a Risk Budget

Four separate amounts should be tracked:

A broker’s margin model is designed for collateral and default-risk management. It is not a promise that losses will remain within the requirement. A participant’s internal risk budget should consider stress moves, gaps, correlated positions, cash availability, and forced-liquidation costs.

Worked Example: Margin Liquidity

Assume the eight-contract position above has $400,000 of notional exposure. A 4% adverse price move creates an approximate $16,000 loss:

If the account began with $20,000 of collateral allocated to the position, the loss consumes most of that amount before any margin increase, fees, or basis effects. The broker can require additional cash or reduce the position under the account agreement. The example does not imply that 4% is a maximum market move.

Offset, Cash Settlement, and Delivery

Offset

A trader commonly closes a position by taking an equal and opposite position in the same contract month. For example, selling one contract offsets an existing long position in that contract.

Cash settlement

Some contracts settle by comparing a final settlement value with the contract position and paying the resulting cash difference. Stock index futures are a common example because the index itself cannot be delivered.

Physical delivery

Other contracts permit or require delivery under exchange rules. Delivery is not simply a shipment at any time or place; quality, location, notice, timing, and approved-document requirements apply. A trader who does not intend to deliver should know the broker’s liquidation deadline, which can be earlier than the exchange’s last trading or notice date.

Last Trade, Daily Settlement, and Final Settlement

Several prices can appear for the same contract, and they serve different purposes:

The daily settlement price does not have to equal the last trade. Exchanges can use product-specific calculation windows and procedures, particularly when trading is thin or disrupted. Final settlement can use another benchmark, observation time, average, opening procedure, closing value, or delivery invoice rule.

An account statement should be reconciled to the applicable settlement price rather than a quote captured at an unrelated time.

Expiration and Roll Decisions

Contract month, last trading day, first notice day, and final settlement or delivery day are not synonyms. Their sequence varies by product. Broker deadlines and customer restrictions can occur earlier than exchange deadlines.

A position needed beyond the current expiration can be rolled forward by closing the near contract and opening a later one. The later contract can have a different price, liquidity, basis, multiplier, margin, or settlement exposure.

The price difference between contract months is not automatically an immediate gain or loss. The old contract realizes its accumulated P&L, while the new contract opens at its current market price. Subsequent price movement and the strategy’s sizing method determine the result.

Why Businesses and Investors Use Futures

Hedging

A producer expecting to sell a commodity may take a short futures position to reduce exposure to a price decline. A business expecting to buy may take a long position to reduce exposure to a price increase. Portfolio managers also use financial futures to adjust equity beta, duration, currency, or volatility exposure.

The futures gain or loss rarely matches the underlying exposure perfectly. Quantity, quality, location, maturity, benchmark, and timing differences create Basis Risk.

Worked Example: Producer Hedge

Assume a producer expects to sell 10,000 units in three months. A matching hypothetical futures contract represents 1,000 units, so the producer sells 10 contracts at $50 per unit.

At the sale date, assume:

• the local cash price is $44 per unit;
• the futures position is closed at $44; and
• quantity, quality, location, and timing match exactly for this simplified example.

The cash sale produces:

The short futures gain is:

The simplified combined proceeds are $500,000, equivalent to $50 per unit before brokerage, margin funding, tax, and other costs.

The result is not a guaranteed selling price. If the local cash basis changes, output is only 8,000 units, grade differs, or the sale date does not match the futures month, the hedge leaves a residual. Keeping all 10 short contracts after production falls to 8,000 units would create an extra short exposure of 2,000 units.

Taking market exposure

A futures position can create directional or relative-value exposure without paying the full notional amount upfront. That leverage makes the instrument capital-efficient, but it also allows losses to exceed the initial margin.

Price discovery

Trading across contract months produces observable prices for different future settlement periods. Those prices reflect current supply, demand, financing, carrying costs, income, and market expectations; they are not guaranteed forecasts of future spot prices.

A futures price belongs to a specific contract and month. Analysts should distinguish the last trade, bid, ask, daily settlement price, and final settlement value. For a deeper pricing treatment, see Futures Price.

Volume and Open Interest

Volume counts trading activity over a stated period. Open interest counts contracts that remain open under the reporting convention. They answer different questions.

• High volume can indicate active trading today without proving that a large position can be exited at one price.
• High open interest can indicate substantial outstanding positions without showing current bid-ask depth.
• A deferred or expiring month can have different liquidity from the most active month.
• Reported totals do not replace order-book depth, spread, time-of-day, and market-impact analysis.

Closing an existing long against a new seller can reduce open interest, while a new buyer and new seller can increase it. Trade classification and reporting rules matter, so simple inferences from one day’s totals can be unreliable.

Futures vs. Forward Contract

Futures vs. Options on Futures

An option on futures is not a futures position until exercise or assignment creates one, unless the product settles another way. The option’s expiration can also precede the underlying future’s expiration.

Common Mistakes

• Treating initial margin as the amount invested or maximum possible loss.
• Calculating P&L from price change without applying contract size, multiplier, quantity, and direction.
• Buying when the intended hedge requires selling, or vice versa.
• Using the active contract’s price while placing an order in another month.
• Assuming the last trade is the daily or final settlement price.
• Ignoring daily cash settlement because the position is intended to be held longer.
• Matching a hedge by notional while ignoring quantity, quality, location, timing, benchmark, or sensitivity.
• Assuming exchange trading guarantees liquidity at the desired price.
• Missing a broker deadline because only the exchange’s last trading day was reviewed.
• Rolling the same number of contracts without recalculating notional or risk.

Risks and Limitations

• Leverage: A small price change applied to a large notional exposure can create a substantial gain or loss.
• Margin liquidity: Losses and higher requirements can demand cash on short notice.
• Basis risk: The contract may not track the asset, rate, location, or date being hedged.
• Gap and limit risk: Prices may move sharply or trading may be constrained, delaying an exit.
• Delivery risk: Failing to close a deliverable contract can create notice, financing, storage, or delivery obligations.
• Roll risk: Maintaining exposure beyond expiry requires a new contract that may trade at a different price.
• Operational risk: Wrong contract month, multiplier, order direction, or settlement assumption can materially alter exposure.
• Clearing and intermediary risk: Clearing reduces bilateral exposure but does not eliminate risks involving brokers, clearing members, collateral, operations, or market disruption.

Due-Diligence Checklist

1. Calculate notional exposure and value per tick.
2. Stress daily losses and margin calls rather than considering only initial margin.
3. Match the contract unit, grade, benchmark, location, and month to the exposure.
4. Identify the broker’s last date for closing or financing a deliverable position.
5. Check settlement-price and disruption rules.
6. Plan the offset, roll, cash settlement, or delivery process before entering.
7. Review tax, accounting, legal, and regulatory treatment for the specific participant and jurisdiction.
8. Distinguish bid, ask, last trade, daily settlement, and final settlement in records.
9. Reconcile daily account cash flows with contract-level P&L and fees.
10. Reassess the position when the underlying commercial or portfolio exposure changes.
