Futures Contract
Why Futures Matter
Futures are the backbone of global commodity and financial markets. Airlines hedge jet fuel costs with crude oil futures. Farmers lock in crop prices months before harvest. Asset managers adjust equity exposure instantly with index futures. Central banks watch interest rate futures to gauge market expectations for policy moves.
The sheer scale is staggering — the notional value of futures traded globally dwarfs the equity markets. Futures exist because producers, consumers, and speculators all benefit from a standardized, liquid way to transfer price risk across time.
How a Futures Contract Works
Opening a position. You don’t “buy” a futures contract like you buy a stock. You enter into it. Going long means you agree to buy at the contract price at expiration. Going short means you agree to sell. No money changes hands upfront — you only post margin (a performance bond, typically 3–12% of the contract’s notional value).
Daily mark-to-market. Every trading day, the exchange settles gains and losses. If you’re long and the futures price rises $500, that $500 is credited to your margin account. If it drops $500, it’s debited. This daily settlement is what distinguishes futures from forwards and virtually eliminates the risk that the other side can’t pay at expiration.
Closing or delivery. Most futures positions are closed before expiration by entering an offsetting trade (sell if you’re long, buy if you’re short). Only a small fraction — especially in physical commodity contracts — go to actual delivery. Financial futures (index, interest rate, currency) typically settle in cash.

Futures Pricing: Cost of Carry
Where S is the spot price, r is the risk-free interest rate, q is the dividend yield (for equity futures) or storage/convenience yield (for commodities), and T is time to expiration. The futures price reflects the cost of holding the underlying until delivery — financing costs minus any income the asset generates.
When the futures price exceeds the spot price (F > S), the market is in contango — typical when carry costs are positive. When futures trade below spot (F < S), it's called backwardation — common in commodity markets when near-term supply is tight.
Margin and Leverage
Futures are inherently leveraged. An E-mini S&P 500 contract controlling roughly $250,000 in notional value might require only $12,000 in margin — roughly 20:1 leverage. This cuts both ways: a 1% index move generates a 20% gain or loss on your margin deposit.
If your account falls below the maintenance margin, the exchange issues a margin call — you must deposit additional funds immediately or your position is liquidated. There’s no grace period. This forced liquidation mechanism, combined with daily settlement, is how the exchange prevents losses from accumulating to dangerous levels.

Who Uses Futures and Why
Hedgers use futures to lock in prices and reduce risk. An airline buys crude oil futures to cap fuel costs. A wheat farmer sells futures to guarantee a price for the next harvest. A bond portfolio manager sells Treasury futures to reduce duration exposure. In each case, the hedger is transferring price risk to someone willing to take it.
Speculators take on that risk in pursuit of profit. They provide liquidity and ensure hedgers can find counterparties. Without speculators, futures markets would be thin and hedging costs would be much higher.
Arbitrageurs keep futures prices aligned with fair value. If a futures contract trades above its theoretical cost-of-carry price, an arbitrageur can sell the future, buy the underlying, and lock in a risk-free profit — pushing the prices back into line.
Key Takeaways
- A futures contract is a standardized, exchange-traded obligation to buy or sell an asset at a set price on a future date.
- Daily mark-to-market and clearinghouse backing eliminate counterparty risk — the key structural advantage over forwards.
- Futures are inherently leveraged — initial margin is a fraction of notional value, amplifying both gains and losses.
- Pricing follows cost-of-carry logic: futures price = spot + financing costs − income from the underlying.
- Hedgers, speculators, and arbitrageurs each play essential roles in keeping futures markets liquid and fairly priced.
FAQ
Do I have to take delivery of the underlying asset?
Almost never. The vast majority of futures positions are closed before expiration by entering an offsetting trade. Financial futures (indices, rates, currencies) are cash-settled — no physical delivery is possible. For physical commodity futures, delivery procedures exist but are used by a tiny fraction of participants.
What happens if I can’t meet a margin call?
Your broker will liquidate your position — potentially at a very unfavorable price. There’s no negotiation period. This is by design: the exchange’s integrity depends on immediate settlement of losses. Never enter a futures position without sufficient capital to absorb adverse moves beyond the initial margin.
How are futures different from options on futures?
A futures contract is an obligation — you must buy or sell. An option on a future gives you the right but not the obligation to enter a futures position. Options on futures combine the leverage of futures with the asymmetric payoff of options, and they’re widely traded on energy, agricultural, and interest rate contracts.
Can retail investors trade futures?
Yes. Most major brokerages offer futures trading, though they require a separate futures account and typically impose minimum capital requirements. Micro futures contracts (like the Micro E-mini S&P 500 at 1/10th the standard size) were specifically designed to make futures accessible to smaller accounts.
What’s the difference between the futures price and the spot price?
The difference is called the “basis” (Futures Price − Spot Price). Basis reflects the cost of carry — financing, storage, insurance, minus any income from holding the asset. As expiration approaches, the basis converges toward zero because the cost of carry shrinks to nothing. At expiration, the futures price equals the spot price.
