Futures Contracts

A standardised agreement to transact at a set price on a future date. Unlike an option, both parties are obliged, and the exposure is the full contract value.

MadStockAlerts Research · Updated August 29, 2026

What to take away

  • Both sides are obliged; a future is not an option to do anything.
  • Contract terms are standardised by the exchange, with only the price negotiated.
  • The notional exposure is far larger than the margin posted.
  • Positions are marked to market daily, with cash moving each day.
  • Contracts expire, so maintaining exposure requires rolling.

An Agreement, Not a Purchase

A futures contract commits both sides to a transaction on a future date, which is why the margin is a performance bond rather than a down payment.

How a future differs from an option

OptionFuture
Buyer's positionA right, not an obligationAn obligation
Maximum loss for the buyerThe premiumSubstantial, and not capped by the position's cost
Cost at entryThe premiumNo premium; margin is posted as collateral
Daily cash flowsNone until closedMarked to market daily
ExposureDelta-adjustedThe full contract notional

The second row is the distinction that matters most for risk. A long option cannot lose more than was paid; a long futures position can lose far more than the margin posted, and the obligation is symmetric.

The notional exposure

A futures contract represents a defined quantity of the underlying, and the position's exposure is that quantity multiplied by the price. The margin posted is a performance bond rather than a purchase price, and it is a small fraction of the exposure.

notional value = contract multiplier x index or price level

  • an equity index future with a $50 multiplier at 5,000 has a notional of $250,000
  • the margin required might be a low tens of thousands, which is where the leverage comes from

This is the single most common source of unintended risk in futures. Sizing a position by the margin required rather than by the notional exposure produces a position many times larger than intended, and the arithmetic is unforgiving.

Margin is not the position size
What is postedWhat is actually exposed

  4. = the notional exposureThe number a position should be sized against
Sizing by the margin required rather than by the notional exposure produces a position many times larger than intended. The arithmetic is unforgiving and it is the most common source of unintended risk here.

Expiry and rolling

Every contract has a delivery month, and maintaining exposure beyond it requires closing the expiring contract and opening the next one. That transaction is the roll.

  • The roll is executed at whatever spread exists between the two contracts, which is a cost or a benefit.
  • Some contracts settle physically, which is a genuine obligation to deliver or receive.
  • Most financial futures settle in cash against a reference value.
  • Continuous price series used for charting are constructed by splicing contracts, and the splicing method changes the history.

The last point matters for anyone analysing futures charts. A continuous series is a construction, and back-adjusted and unadjusted versions of the same series produce different levels and different indicator values.

What they are used for

UseCharacter
Hedging a commercial exposureThe original purpose. A producer or consumer fixing a price
Hedging a portfolioAn index future offsets equity exposure without selling holdings
Expressing a directional viewEfficient, and with leverage that requires careful sizing
Accessing markets around the clockMany contracts trade nearly continuously

The first row is why these markets exist, and the terms of every contract reflect it: delivery points, grades and quantities are specified because someone at the end of the chain may actually deliver.

The contract families

Futures exist on a wide range of underlyings, and the families differ in what drives them and in who the natural participants are.

FamilyExamplesNatural hedgers
Equity indexBroad index contractsPortfolio managers adjusting exposure
Interest rateGovernment bond and short-rate contractsBanks and bond portfolios
EnergyCrude, natural gas, refined productsProducers, refiners and large consumers
AgriculturalGrains, softs, livestockFarmers and processors
MetalsPrecious and industrialMiners and manufacturers
CurrencyMajor pairsCompanies with cross-border revenue

The third column is the reason these markets exist and it is also why the contracts have the specifications they do. Delivery points, grades and quantities were set for the people in that column rather than for a speculator.

Micro and mini contracts on many of these were introduced specifically to make smaller position sizes possible. They are the same exposure at a smaller multiplier.
