What Is a Futures Contract?

A futures contract is a standardized legal agreement to buy or sell a specific commodity, currency, or other financial instrument at a predetermined price at a specified time in the future. These contracts are a fundamental type of derivatives and are traded on organized exchanges. Unlike a direct purchase or sale of an asset at its current spot price, a futures contract obligates both the buyer (who takes a long position) and the seller (who takes a short position) to fulfill the transaction on the agreed-upon future date. This obligation differentiates futures from options contracts, which give the holder the right, but not the obligation, to buy or sell. Futures contracts are primarily used for hedging against price fluctuations or for speculation on future price movements.

History and Origin

The origins of modern futures trading can be traced to agricultural markets in the mid-19th century United States. Farmers and merchants sought ways to mitigate the price uncertainty inherent in agricultural commodities between planting and harvest. Early forms of these agreements, known as "to-arrive" contracts or forward contracts, allowed parties to agree on a price for future delivery. However, these were often informal and carried significant counterparty risk.

The need for more standardized and reliable agreements led to the formalization of futures trading. The Chicago Board of Trade (CBOT), established in 1848, played a pivotal role in this evolution. Initially a cash market for grain, the CBOT began trading forward contracts almost immediately. By 1865, the CBOT introduced standardized "futures contracts," which formalized trading rules and introduced the concept of performance bonds, or margin, to secure trades. This standardization, along with the establishment of a clearing house in 1883, significantly reduced credit risk and paved the way for the robust futures markets seen today. The Commodity Futures Trading Commission (CFTC) provides a detailed history of the evolution of these markets and their regulation in the United States.⁴

Key Takeaways

• A futures contract is a legally binding agreement to buy or sell an asset at a predetermined price on a future date.
• They are standardized and traded on regulated exchanges, ensuring transparency and reducing counterparty risk.
• Futures are used by producers and consumers for hedging price risk and by investors for speculating on future price movements.
• The contract's value fluctuates with changes in the underlying asset's price, leading to daily gains or losses through the process of marking to market.
• Futures contracts allow for significant leverage, meaning a small initial capital outlay can control a large notional value of the underlying asset.

Formula and Calculation

The profit or loss for a futures contract is relatively straightforward, depending on the difference between the entry price and the settlement price (or the price at which the position is closed).

For a long position (buying a futures contract):
$\text{Profit/Loss} = (\text{Exit Price} - \text{Entry Price}) \times \text{Contract Multiplier}$

For a short position (selling a futures contract):
$\text{Profit/Loss} = (\text{Entry Price} - \text{Exit Price}) \times \text{Contract Multiplier}$

Where:

• Entry Price: The price at which the futures contract was initially bought or sold.
• Exit Price: The price at which the futures contract was later sold (for a long position) or bought back (for a short position), or the final settlement price.
• Contract Multiplier: A standardized value determined by the exchange that dictates the notional value of one contract. For example, a crude oil futures contract might represent 1,000 barrels of oil, so its multiplier would be 1,000. This multiplier allows for the calculation of the total dollar value of the profit or loss from a per-unit price change.

Interpreting the Futures Contract

Interpreting a futures contract involves understanding its standardized terms, which typically include the underlying asset, contract size, expiration date, and delivery specifications (if applicable). The price of a futures contract reflects the market's collective expectation of the underlying asset's price at the specified future date. This expected future price is a key output of the futures market's price discovery mechanism.

Traders and analysts observe futures prices to gauge market sentiment and anticipate future supply and demand dynamics. For instance, a rise in crude oil futures prices for distant months might indicate expectations of future supply shortages or increased demand. Conversely, a decline could suggest an anticipated surplus. The relationship between different futures contract prices for the same underlying asset, but with different expiration dates, is known as the futures curve and provides additional insights into market expectations, including potential contango or backwardation scenarios. Understanding the liquidity of a particular futures contract, reflected in its trading volume and open interest, is also crucial for interpreting its efficiency and ease of trading.

Hypothetical Example

Consider a farmer who expects to harvest 5,000 bushels of corn in three months. The current spot price for corn is $5.00 per bushel, but the farmer is concerned that prices might fall by harvest time. To hedge against this risk, the farmer decides to sell five corn futures contracts, each representing 1,000 bushels, with an expiration date three months from now, at a price of $5.10 per bushel.

1. Farmer's Action: Sells 5 corn futures contracts at $5.10/bushel.
2. Total Notional Value: 5 contracts * 1,000 bushels/contract = 5,000 bushels. 5,000 bushels * $5.10/bushel = $25,500.

Three months later, at harvest time, two scenarios are possible:

Scenario A: Corn prices fall
The spot price of corn falls to $4.80 per bushel. The farmer sells their physical corn in the cash market at $4.80/bushel. To offset the futures position, they buy back their five futures contracts at the current futures price, which has also fallen to $4.80/bushel (assuming convergence).

• Loss on physical corn: ($5.10 - $4.80) * 5,000 bushels = $1,500
• Profit on futures contracts: ($5.10 - $4.80) * 5,000 bushels = $1,500

In this scenario, the loss on the physical crop is offset by the gain in the futures market, effectively locking in a price close to the initial futures contract sale price.

Scenario B: Corn prices rise
The spot price of corn rises to $5.30 per bushel. The farmer sells their physical corn in the cash market at $5.30/bushel. To offset the futures position, they buy back their five futures contracts at the current futures price, which has also risen to $5.30/bushel.

• Gain on physical corn: ($5.30 - $5.10) * 5,000 bushels = $1,000
• Loss on futures contracts: ($5.30 - $5.10) * 5,000 bushels = -$1,000

Here, the farmer gains on the physical crop but loses on the futures position. However, their overall effective price remains near their initial hedged price, demonstrating how futures contracts can provide price stability.

Practical Applications

Futures contracts are integral to various sectors of the financial world and real economy.

1. Risk Management (Hedging): Businesses use futures to manage price risk for their inputs or outputs. Airlines might buy jet fuel futures to lock in fuel costs, while mining companies might sell gold futures to ensure a price for future production. This allows companies to stabilize their budgets and financial planning.
2. Price Discovery: Futures markets serve as a centralized hub for buyers and sellers worldwide to aggregate information and form expectations about future prices. The large volume of data generated by futures trading, accessible through exchanges like CME Group, provides valuable insights into anticipated supply and demand dynamics across various asset classes, including energy, metals, agricultural products, and financial instruments.³
3. Speculation: Traders with a view on future price movements can use futures to profit from those expectations. A speculator might buy crude oil futures if they anticipate geopolitical events will drive prices higher, or sell stock index futures if they expect a market downturn.
4. Arbitrage: Futures contracts can also be used in arbitrage strategies where traders exploit small price discrepancies between the futures market and the underlying cash market or between different futures contracts.
5. Portfolio Diversification: Institutional investors may use futures contracts to gain exposure to different asset classes or geographies efficiently, contributing to overall portfolio diversification strategies.
6. Regulatory Oversight: The trading of futures contracts in the U.S. is subject to strict regulatory oversight by the Commodity Futures Trading Commission (CFTC) under the Commodity Exchange Act (CEA). This regulatory framework is designed to ensure fair and transparent markets, protect market participants, and prevent manipulation.²

Limitations and Criticisms

While futures contracts offer significant benefits, they also come with limitations and criticisms. One primary concern is the inherent volatility of futures markets, which, combined with high leverage, can lead to substantial losses for unprepared participants. Traders can lose more than their initial margin deposit if prices move unfavorably, necessitating additional margin calls.

Another area of discussion revolves around market efficiency. While futures prices are generally considered good indicators of future spot prices, the concept of market efficiency in commodity futures markets is a complex topic with varying empirical findings. Some academic research suggests that, for certain commodities, expected excess returns to futures speculation are not always zero, potentially indicating the presence of a risk premium or short-term inefficiencies.¹ This implies that while futures markets perform well in their forecasting role, there might be instances where they do not perfectly reflect all available information instantly.

Furthermore, the complexity of some futures contracts and the need for continuous monitoring can be challenging for individual investors. The requirement to manage a margin account and be aware of daily marking-to-market can add stress and financial burden. Critics also point to instances where large speculative positions might exacerbate price swings, though regulatory bodies like the CFTC implement position limits to mitigate such risks.

Futures Contract vs. Forward Contract

While often confused, futures contracts and forward contracts have key distinctions, primarily in their standardization, trading venue, and associated risks. Both are agreements to buy or sell an asset at a predetermined price on a future date, but their structures differ significantly:

The standardized nature and exchange-based trading of a futures contract make it highly liquid and reduce the risk of default compared to the more flexible but riskier forward contract.

FAQs

1. What is the main purpose of a futures contract?

The primary purposes of a futures contract are to allow parties to hedge against future price fluctuations of an underlying asset and to enable speculation on those price movements. For example, a company that needs to buy a large quantity of a specific commodity in the future might use futures to lock in a price today.

2. Can I lose more than I invest in a futures contract?

Yes, it is possible to lose more than your initial margin deposit in a futures contract. Futures trading involves leverage, meaning a small amount of capital controls a much larger notional value of the asset. If the market moves significantly against your position, losses can exceed the initial margin, requiring additional funds (margin calls) to be deposited into your margin account.

3. What types of assets can be traded with futures contracts?

A wide range of assets can be traded using futures contracts. These include agricultural commodities (like corn, wheat, soybeans), energy products (crude oil, natural gas), metals (gold, silver), currencies, interest rates, and stock indices (like the S&P 500 or Nasdaq 100). These are all examples of financial instruments that can be standardized for futures trading.
