A futures contract turns an expectation about a future price into a standardized agreement. Buyers and sellers commit to transact according to terms established by an exchange, including the underlying asset, contract size, price quotation, expiry month, and settlement method.
In futures trading, participants do not need to pay the full value of the contract upfront. They post margin, which acts as financial security against losses. This structure gives producers, asset managers, companies, and speculators efficient exposure, but it also makes relatively small price movements significant at the account level.
The deposit is smaller than the position. The economic exposure is not.
Standardized Contracts Create a Common Market
Every futures contract follows published specifications. A crude oil contract represents a defined quantity and grade of oil. An equity-index contract has a stated point value. Agricultural contracts specify the commodity quality, delivery location, and eligible settlement period.
Standardization allows contracts to trade between participants who may have very different objectives. A wheat producer can sell futures to reduce exposure to falling prices. A food manufacturer can buy them to limit the cost of future supply. A speculator can trade the same contract without producing or consuming wheat.
The exchange’s clearing process stands between buyers and sellers, reducing the need for each participant to evaluate the other party directly. Positions are still exposed to market risk, and traders remain responsible for meeting margin requirements.
Contract size deserves attention before any order is placed. A movement of one point may represent $5, $50, or another amount depending on the product. Similar-looking charts can create dramatically different financial results.
Initial margin is the amount required to open a position. Maintenance margin is the minimum equity generally needed to keep it open. If losses reduce the account below the required level, additional funds may be requested or the position may be liquidated.
Futures accounts are marked to market. Gains and losses are calculated as prices change and are reflected in account equity. This differs from waiting until the contract expires to determine the full result.
Consider an E-mini S&P 500 position held before a US inflation report. Hotter-than-expected data sends index futures sharply lower as Treasury yields rise. A long position immediately loses value, and the account’s available margin contracts. If exposure is too large, the trader may be forced out before the market has time to stabilize.
The economic opinion might remain unchanged. The margin system still acts on the current loss.
Counterintuitively, a low margin requirement can make a contract more dangerous rather than more affordable. It permits greater exposure relative to deposited capital. Whether that exposure is appropriate remains a separate calculation.
Expiry and the Rolling Process
Futures contracts have expiration dates. Trading activity usually migrates from the nearest contract to a later month as expiry approaches. This process is known as rolling.
A trader who wants to maintain exposure can close the expiring contract and open a position in the next active month. The two contracts may trade at different prices because storage costs, financing, seasonal demand, expected supply, and interest rates affect the futures curve.
When later contracts trade above near-term contracts, the market is commonly described as being in contango. When later prices are lower, the structure is called backwardation.
Rolling does not create an automatic gain or loss simply because the new contract has a different quoted price. The position closes one instrument and opens another with its own valuation. Still, repeated rolls can affect long-term performance, particularly when the curve remains steep.
Beginners often focus on the direction of the underlying asset. Experienced traders also watch which contract carries the most volume and how the curve is shaped.
Cash-settled contracts conclude through a financial adjustment based on a reference price. Equity-index futures commonly use this method because delivering a mathematical index would be impossible.
Physically settled contracts can require delivery of the underlying asset if an eligible position remains open through the relevant deadline. The exact process varies by product and exchange. Most speculative traders close or roll before delivery becomes an issue, while commercial participants may use delivery as part of their business operations.
The counterparty obligation does not disappear because a trader never intended to receive the commodity.
Broker deadlines may arrive before the exchange’s final settlement date. Firms can restrict trading, increase margin, or close positions as delivery approaches. These rules should be reviewed before entering, not during expiry week.
Before beginning futures trading, record the contract symbol, point value, total notional exposure, initial and maintenance margin, last trading day, settlement method, and current rollover schedule. Then calculate the loss from an ordinary adverse move, not merely the minimum movement. If the contract’s basic specifications are not clear, the chart is not yet the most important source of information.
