Futures

The seller of the futures contract, called the short position, is obligated to sell the underlying asset at the agreed price on the delivery date. 

Key Characteristics of Futures Contracts

Unlike forward contracts, which are privately negotiated bilateral agreements traded over the counter, futures contracts are standardised instruments traded on regulated exchanges with centralised clearing through a central counterparty that eliminates bilateral credit risk between the buyer and seller.

The futures market serves two fundamental economic functions that together justify its existence and explain its enormous size. First, futures provide a mechanism for hedging, allowing producers, consumers, and financial institutions to transfer unwanted price risk to counterparties who are willing to bear it. 

A wheat farmer who has planted a crop can lock in the price they will receive at harvest by selling wheat futures, protecting themselves against a fall in wheat prices before the crop is ready for sale. 

An airline that needs to purchase jet fuel can lock in the cost by buying crude oil futures, protecting themselves against a rise in energy prices. Second, futures markets attract speculators who are willing to assume the price risk that hedgers wish to transfer, providing the liquidity and price discovery that make the market function efficiently. 

The speculator who buys wheat futures from the farmer bears the risk that wheat prices may fall, but profits if they rise, accepting this risk in exchange for the potential profit that the price movement might provide.

Futures markets have existed in various forms for centuries, with organised grain futures trading in the United States dating to the establishment of the Chicago Board of Trade in 1848. 

Today the global futures market encompasses contracts on commodities including grains, livestock, energy, and metals, financial instruments including equity indices, interest rates, currencies, and government bonds, and various other underlying variables. 

The total notional value of outstanding futures contracts across all markets runs into the tens of trillions of dollars, reflecting the enormous importance of futures in the management of price risk across the global economy.

Key Structural Features of Futures Contracts

The standardisation of futures contracts is what distinguishes them from over-the-counter forward contracts and is what makes them exchange-tradeable, liquid instruments rather than bespoke bilateral agreements. Understanding the key structural features of futures contracts is essential for understanding how they function and how they differ from other derivative instruments.

The underlying asset and contract specifications are defined by the exchange and are identical for all contracts of the same type. For a commodity futures contract, the specifications include the exact grade, quality, and quantity of the commodity, the permissible delivery locations, and the delivery months available for trading. For financial futures contracts, the specifications define the underlying financial instrument, the contract size, and the cash settlement methodology used when physical delivery is not practical. The standardisation of these specifications creates the fungibility that allows any buyer of a contract to offset their position by selling the same contract, and any seller to offset by buying the same contract, without the need to find the original counterparty.

The futures price is the price agreed today for delivery or settlement on the specified future date. The futures price is determined by the continuous auction process of buyers and sellers on the exchange floor or electronic trading platform, where supply and demand forces determine the market clearing price at any given moment. The futures price is related to, but not identical to, the current spot price of the underlying asset, with the difference between the two prices called the basis. For financial futures on assets that can be financed and stored at known cost, the theoretical futures price is determined by the cost of carry relationship: the futures price equals the spot price plus the financing cost of carrying the underlying asset to the delivery date minus any income or dividends received from the asset during the carrying period.

The delivery date, also called the expiration date or settlement date, is the date on which the contract requires the delivery of the underlying commodity or the cash settlement of the contract's final value. Most futures traders do not actually intend to deliver or receive the physical commodity and instead close their positions before the delivery date by executing an offsetting trade, selling if long or buying if short, that cancels their obligation. The small percentage of contracts that proceed to delivery are settled through the exchange's established delivery procedures for the specific contract.

The Clearing and Margin System

The most important structural feature that distinguishes futures from over-the-counter forward contracts is the central clearing and daily mark-to-market margin system that eliminates bilateral counterparty credit risk and ensures the financial integrity of the market.

When a futures trade is executed on an exchange, the original bilateral agreement between buyer and seller is immediately replaced by two separate agreements: the buyer's contract runs with the central counterparty clearinghouse, and the seller's contract also runs with the clearinghouse. The clearinghouse interposes itself as the buyer to every seller and the seller to every buyer, guaranteeing the performance of both sides of every contract. This novation eliminates the credit risk of any specific counterparty from the perspective of each trader, replacing it with the credit risk of the clearinghouse itself, which is backed by multiple layers of financial protection including margin deposits, clearing member guarantees, and the clearinghouse's own capital.

Initial margin is the deposit that each party to a futures contract must post with the clearinghouse at the time the contract is entered into. Initial margin is not a down payment or partial payment for the contract; it is a performance bond designed to provide the clearinghouse with a financial cushion against potential losses if a trader defaults before their position can be closed out. Initial margin is set by the exchange based on the price volatility of the contract and is typically calculated as a percentage of the total contract value, ranging from a few percent for less volatile financial futures to higher percentages for more volatile commodity contracts.

Daily mark-to-market settlement is the mechanism through which gains and losses on open futures positions are settled each day based on the change in the futures price from the previous day's settlement price to the current day's settlement price. At the end of each trading day, positions are marked to their current market value and the gain or loss is credited to or debited from the trader's margin account. A trader whose position has moved in their favour receives a cash credit to their margin account equivalent to the day's gain. A trader whose position has moved against them has a cash debit from their margin account equivalent to the day's loss.

Maintenance margin is the minimum level of margin the trader must maintain in their account. If daily losses reduce the account balance below the maintenance margin level, the trader receives a margin call requiring them to deposit additional funds to restore the account to at least the initial margin level. If the trader fails to meet the margin call, the clearinghouse can close out the position to prevent further losses from accumulating.

The daily settlement and margin system ensures that losses are collected before they accumulate to levels that threaten the trader's ability to pay, maintaining the financial integrity of the market even through periods of extreme price volatility. This is fundamentally different from a forward contract, where any losses accumulate unrealised throughout the life of the contract until final settlement, creating bilateral credit exposure that can be substantial for long-dated contracts.

Leverage in Futures Trading

The margin system of futures trading creates substantial leverage, making futures one of the most leveraged instruments available in financial markets and amplifying both the potential gains and the potential losses from futures positions relative to the capital committed.

Because initial margin is only a small fraction of the total contract value, a relatively small price movement in the underlying asset translates into a large percentage gain or loss on the margin posted. Consider an S&P 500 futures contract with a notional value of five hundred thousand dollars and an initial margin requirement of twenty-five thousand dollars. A one percent move in the S&P 500, representing a change of five thousand dollars in the contract value, represents a twenty percent gain or loss on the twenty-five thousand dollar initial margin. This leverage ratio of twenty to one means that futures traders can control large exposures with relatively small capital commitments, magnifying returns but also magnifying the risk of catastrophic loss.

The leverage inherent in futures trading makes them powerful tools for both hedging and speculation but requires sophisticated risk management to avoid the rapid and potentially unlimited losses that adverse price movements can produce. A hedger who uses futures to offset an existing underlying exposure is mitigating their overall risk despite the leverage in the futures position, because the gain or loss on the futures position is offset by the corresponding gain or loss on the underlying position being hedged. A speculator who uses futures to take a leveraged directional position is amplifying their risk exposure and must carefully size their position relative to their total capital to avoid the margin calls and forced position closures that can occur when markets move against a heavily leveraged position.

Major Categories of Futures Contracts

The futures market encompasses a broad range of underlying assets, with different contract categories serving different economic hedging and speculative functions.

Agricultural futures were the original and historically most important category of futures contracts, providing farmers and agricultural processors with tools to manage the price risk of crops including corn, soybeans, wheat, cotton, and sugar, as well as livestock including cattle and hogs. Agricultural futures markets provide essential price discovery that guides planting decisions, storage decisions, and inventory management throughout the agricultural supply chain. The Chicago Board of Trade and the Chicago Mercantile Exchange, now combined as CME Group, are the primary venues for agricultural futures trading in the United States.

Energy futures cover crude oil, natural gas, gasoline, heating oil, and other petroleum products and have become among the most actively traded and most economically significant futures markets in the world. The West Texas Intermediate crude oil futures contract traded on the New York Mercantile Exchange and the Brent crude oil futures contract traded on the Intercontinental Exchange are the primary global price benchmarks for crude oil and are used by oil producers, refiners, airlines, utilities, and financial institutions to manage energy price risk. Energy price volatility is one of the most significant macroeconomic risk factors affecting inflation, corporate earnings, and economic growth, making energy futures essential tools for a wide range of market participants.

Metals futures cover precious metals including gold, silver, platinum, and palladium, and base metals including copper, aluminium, nickel, and zinc. Gold futures are among the most actively traded precious metals contracts and are used by jewellery manufacturers, mining companies, central banks, and investors seeking exposure to gold as an inflation hedge or safe haven asset. Copper futures are closely watched as an economic indicator because of copper's widespread use in construction and manufacturing, earning it the informal title of Doctor Copper for its supposed ability to predict economic turning points.

Financial futures are the largest category by notional value, encompassing equity index futures, interest rate futures, and currency futures. Equity index futures on the S&P 500, the Nasdaq 100, the Dow Jones Industrial Average, and major international indices allow portfolio managers to adjust their market exposure quickly and efficiently without buying or selling individual stocks, allow hedge funds to take leveraged directional positions on broad market direction, and allow arbitrageurs to exploit pricing discrepancies between the futures price and the fair value implied by the cash index. Interest rate futures on Treasury bonds, Treasury notes, Eurodollars, and SOFR allow fixed income managers to hedge duration risk, allow bond issuers to lock in borrowing costs, and allow traders to express views on the future path of interest rates. Currency futures allow corporations with foreign currency revenue or cost exposure to hedge exchange rate risk and allow traders to take directional positions on relative currency movements.

Hedging with Futures

The hedging application of futures is their most economically important function, allowing businesses and financial institutions to reduce the uncertainty surrounding their future cash flows by locking in prices for the commodities they produce or consume and the financial instruments they hold or need to acquire.

A short hedge is used by a party that already owns or expects to produce the underlying asset and wants to protect against a decline in its value. A corn farmer who plants in spring and expects to harvest in autumn can sell corn futures at the spring planting price, locking in the revenue they will receive for their harvest regardless of what happens to corn prices during the growing season. If corn prices fall by harvest time, the farmer's loss on the physical corn crop is offset by the gain on the short futures position. If corn prices rise, the farmer's gain on the physical crop is offset by the loss on the futures position, but the farmer has accepted this trade-off in exchange for the certainty of the locked-in price.

A long hedge is used by a party that expects to need to purchase the underlying asset in the future and wants to protect against a rise in its price. An airline that needs to purchase jet fuel for the coming year can buy crude oil futures, locking in the cost of its future fuel purchases. If oil prices rise, the airline's higher fuel costs are offset by the gain on the long futures position. If oil prices fall, the airline's lower fuel costs are offset by the loss on the futures position.

The effectiveness of a futures hedge depends on the basis risk, the risk that the futures price and the spot price of the asset being hedged do not move in perfect tandem. As described in the Basis Risk article in Section B, the difference between the futures price and the spot price fluctuates over the life of the hedge and introduces residual risk that the hedge cannot fully eliminate. Careful selection of the most closely correlated futures contract and appropriate sizing of the hedge ratio can minimise but not entirely eliminate basis risk.

Futures Pricing: The Cost of Carry Model

The theoretical relationship between the futures price and the spot price is described by the cost of carry model, which states that the futures price equals the spot price adjusted for the cost of carrying the underlying asset from today until the futures delivery date.

For financial assets that can be financed and that generate income during the carrying period, the cost of carry model states that the futures price equals the spot price multiplied by one plus the risk-free interest rate raised to the power of the time to delivery, minus the future value of any dividends or coupon payments received from the underlying asset during the carrying period. The interest rate component reflects the cost of financing the purchase of the underlying asset, and the income component reflects the benefit of holding the underlying directly rather than through the futures contract.

For physical commodities that incur storage costs during the carrying period, the cost of carry model incorporates storage costs as an additional positive carry component and a convenience yield as a potential negative carry component reflecting the value of having immediate physical access to the commodity, which may be valuable during periods of supply disruption or shortage.

When the actual futures price differs from the theoretical cost of carry price, arbitrage opportunities arise that are rapidly exploited by sophisticated market participants, driving prices back toward the theoretical relationship. This continuous arbitrage activity is what keeps futures prices appropriately related to spot prices and ensures that the futures market provides accurate price discovery rather than distorted price signals.

Regulatory Framework for Futures

Futures markets in the United States are regulated by the Commodity Futures Trading Commission, known as the CFTC, which is the federal agency responsible for regulating the commodity futures and options markets under the Commodity Exchange Act. The CFTC's regulatory mandate covers the exchanges on which futures are traded, the clearing organisations that clear futures transactions, the firms that act as futures commission merchants by accepting and processing customer orders, commodity trading advisers who advise others on futures trading, commodity pool operators who operate pooled investment vehicles that trade futures, and introducing brokers who solicit customers for futures commission merchants.

The regulatory framework for futures is distinct from the securities regulatory framework administered by the SEC, reflecting the different historical origins and economic functions of futures markets relative to securities markets. The distinction between securities, which are regulated by the SEC, and commodities and futures, which are regulated by the CFTC, has been a source of ongoing jurisdictional complexity as financial innovation has created instruments that blend characteristics of both securities and commodity derivatives. The Dodd-Frank Act of 2010 substantially clarified the regulatory jurisdiction of the CFTC and the SEC over various categories of derivatives and strengthened both agencies' oversight of the derivatives markets.

Futures exchanges including CME Group, the Intercontinental Exchange, and others operate as designated contract markets under CFTC oversight, with responsibilities for market surveillance, contract design, and enforcement of trading rules. Futures commission merchants that hold customer funds are subject to specific customer protection requirements including the segregation of customer funds in separate accounts that cannot be commingled with the firm's proprietary capital, providing protection analogous to the customer protection requirements applicable to broker-dealers under SEC rules.

Examination Relevance and Key Takeaways

Futures are tested on the SIE, Series 7, and Series 65 examinations in the context of derivatives, hedging strategies, risk management, and the structure of financial markets. 

Candidates must understand the definition of a futures contract as a standardised exchange-traded agreement to buy or sell an underlying asset at a specified price on a specified future date, the distinction between futures and forward contracts including the role of centralised clearing and daily mark-to-market settlement, the margin system including initial margin, maintenance margin, and margin calls, the leverage created by the margin system and its amplifying effect on gains and losses, the major categories of futures including agricultural, energy, metals, and financial futures, the economic functions of futures including hedging and price discovery, the short hedge and long hedge applications, the cost of carry pricing model, and the regulatory jurisdiction of the CFTC over futures markets.

The core points to retain are these: a futures contract is a standardised exchange-traded obligation to buy or sell a specified asset at a predetermined price on a specified future date; the clearinghouse interposes itself between buyer and seller eliminating bilateral counterparty credit risk; daily mark-to-market settlement credits gains and debits losses from margin accounts each day ensuring losses are collected before they accumulate to dangerous levels; initial margin is a performance bond not a down payment and maintenance margin is the minimum balance below which a margin call is issued; the leverage created by the small margin relative to the total contract value amplifies both gains and losses dramatically; a short hedge protects against falling prices for a position already owned while a long hedge protects against rising prices for an asset to be purchased; the cost of carry model relates the futures price to the spot price through financing costs and any income or storage costs during the carrying period; basis risk is the residual risk that the futures price and hedged asset price do not move in perfect lockstep; and futures markets in the United States are regulated by the CFTC under the Commodity Exchange Act separately from securities markets regulated by the SEC.
