Futures Contract
A futures contract is a standardized, legally binding agreement to buy or sell a specific asset at a predetermined price on a specified future date, traded on regulated exchanges such as the CME Group and cleared through a central counterparty.
Futures contracts originated as a risk management tool for agricultural producers and buyers who needed to lock in prices ahead of harvest. Today, futures markets have expanded to cover equity indexes, interest rates, foreign currencies, energy, metals, and virtually every tradeable asset class. The CME Group — which operates the Chicago Mercantile Exchange (CME), the Chicago Board of Trade (CBOT), and NYMEX — is the world's largest futures exchange operator.
The defining feature of a futures contract is the obligation on both sides. Unlike an option, where the buyer has a right but no obligation, both the buyer and seller of a futures contract are committed. The buyer agrees to accept delivery (or cash settlement) of the asset at the futures price on the delivery date; the seller agrees to provide it. In practice, the vast majority of futures contracts are closed before delivery by entering an offsetting trade, and many contracts (particularly equity index futures) are cash-settled rather than physically delivered.
Futures trade on margin. Rather than paying the full contract value upfront, market participants post an initial margin deposit — a fraction of total notional value — to their futures commission merchant (FCM). Gains and losses are settled daily through a mark-to-market process, and accounts that fall below the maintenance margin threshold receive a margin call requiring additional funds. This daily settlement cycle, managed through the CME Clearing House, ensures that counterparty credit risk is effectively eliminated.
Leverage in futures is substantial. An S&P 500 E-mini futures contract (ES) has a notional value of 50 times the index level. At an index value of 5,000, one ES contract controls $250,000 of exposure, yet the initial margin might be around $15,000 — roughly 6% of notional. This leverage magnifies both gains and losses significantly relative to the margin posted.
Futures serve critical economic functions: producers hedge forward prices, speculators provide liquidity and price discovery, and arbitrageurs link cash and futures markets together through well-understood no-arbitrage pricing relationships.
