What Are Futures Contracts?

Futures contracts are standardized legal agreements to buy or sell a particular asset at a predetermined price on a specified future date. As a type of derivatives, these financial instruments allow market participants to commit to a transaction without requiring immediate exchange of the underlying asset. They belong to the broader category of financial markets and are primarily used for hedging against price risk or for speculation on future price movements. Each futures contract specifies the quality and quantity of the underlying asset, the price, and the delivery date and location.

History and Origin

The origins of futures contracts can be traced back to agricultural markets, where farmers and merchants sought to mitigate the risks associated with volatile crop prices. Early forms of forward-like agreements existed for centuries, but the formalization of exchange-traded futures contracts emerged in the mid-19th century in the United States. The Chicago Board of Trade (CBOT), established in 1848, played a pivotal role in this development. Initially, the CBOT served as a cash market for grain, but it quickly began trading "to-arrive" contracts, which were precursors to modern futures contracts. These agreements helped standardize the buying and selling of agricultural commodities for future delivery⁷.

In 1865, the CBOT formalized these agreements into standardized "futures contracts," establishing clear rules for trading, margin requirements, and delivery procedures, marking the creation of the world's first true futures exchange⁶. The standardization and centralization offered by the CBOT addressed critical issues of credit risk and market efficiency that plagued earlier informal agreements. The growth of futures markets was not without challenges, leading to early regulatory attempts. For instance, a 1917 U.S. Supreme Court case, Chicago Board of Trade v. United States, addressed the legality of the CBOT's "call rule," which restricted off-exchange trading, highlighting the early efforts to ensure orderly markets⁵. Today, the CBOT is part of the CME Group, a leading global derivatives marketplace⁴.

Key Takeaways

• Futures contracts are legally binding agreements to buy or sell an asset at a predetermined price on a future date.
• They are primarily used for hedging price risk or for speculative trading.
• Standardization, exchange trading, and the role of a clearinghouse are defining features of futures contracts, distinguishing them from forward agreements.
• Participants are required to post initial and maintenance margin, which helps manage counterparty risk.
• Futures markets offer price discovery and liquidity for various underlying assets, including commodities, currencies, interest rates, and stock indexes.

Formula and Calculation

The pricing of futures contracts is complex and influenced by various factors, but the theoretical fair value often relates to the current spot price of the underlying asset, adjusted for the cost of carry. The cost of carry includes expenses like storage costs, insurance, and financing costs, minus any income generated by holding the asset (e.g., dividends for stocks, yield for bonds).

For a non-dividend paying stock or commodity that can be stored, the theoretical futures price (F_0) can be estimated using the formula:

Where:

• (F_0) = Futures price today
• (S_0) = Spot price today
• (e) = The base of the natural logarithm (approximately 2.71828)
• (r) = Risk-free interest rate (annualized)
• (c) = Storage cost as a percentage of the spot price (annualized)
• (T) = Time to expiration (in years)

This formula represents the cost of buying the asset today and holding it until the futures contract's expiration, including the financing cost and storage. For financial assets like currencies or interest rates, the cost of carry formula adjusts to reflect interest rate differentials.

Interpreting Futures Contracts

Interpreting futures contracts involves understanding their price relative to the current spot market and the implications for future supply and demand. If the futures price is higher than the current spot price, it is known as "contango," suggesting that market participants expect the price of the underlying asset to increase over time, or it reflects the cost of carry. Conversely, if the futures price is lower than the spot price, it is called "backwardation," often indicating expectations of future price decreases or a shortage of the asset in the near term.

The difference between the futures price and the spot price provides insights into market expectations regarding future supply and demand conditions, interest rates, and storage costs. Traders and analysts constantly monitor this relationship to inform their trading strategies and risk management decisions. The maturity date of the futures contract is also crucial, as prices for contracts expiring sooner may behave differently from those with longer expirations.

Hypothetical Example

Consider a hypothetical example involving crude oil futures. A refiner needs to purchase 1,000 barrels of crude oil in six months. The current spot price of crude oil is $80 per barrel. The refiner is concerned that oil prices might rise significantly over the next six months, increasing their production costs.

To hedge this price risk, the refiner decides to buy one crude oil futures contract (which typically represents 1,000 barrels) with a delivery date six months in the future. The current futures price for this contract is $82 per barrel.

• Action: The refiner buys one crude oil futures contract at $82/barrel, locking in the price for 1,000 barrels.
• Scenario 1: Oil prices rise. In six months, the spot price of crude oil rises to $90 per barrel.
  • The refiner fulfills their physical need by buying oil in the spot market at $90/barrel.
  • Simultaneously, the futures contract they hold is now worth $90/barrel (assuming the futures price converges to the spot price at expiration). The refiner can sell their futures contract for a profit of ($90 - $82 = $8) per barrel, or (1,000 \text{ barrels} \times $8/\text{barrel} = $8,000).
  • The profit from the futures contract offsets the higher cost of buying crude oil in the spot market, effectively allowing the refiner to pay an average of $82 per barrel.
• Scenario 2: Oil prices fall. In six months, the spot price of crude oil falls to $75 per barrel.
  • The refiner buys oil in the spot market at $75/barrel.
  • The futures contract they hold is now worth $75/barrel. The refiner sells their futures contract for a loss of ($82 - $75 = $7) per barrel, or (1,000 \text{ barrels} \times $7/\text{barrel} = $7,000).
  • The loss from the futures contract is offset by the lower cost of buying crude oil in the spot market, again effectively resulting in an average price close to $82 per barrel.

This example illustrates how futures contracts can be used for hedging, enabling businesses to manage commodity price volatility.

Practical Applications

Futures contracts are widely used across various sectors of the financial markets and real economy:

• Commodity Markets: Farmers use agricultural futures (e.g., corn, wheat) to lock in prices for their crops, while food processors use them to secure raw material costs. Energy companies use crude oil and natural gas futures to manage exposure to price fluctuations. Metal producers and consumers similarly use futures for gold, silver, and copper.
• Currency Markets: Importers and exporters use currency futures to hedge against adverse movements in exchange rates, protecting the value of their international transactions.
• Interest Rate Markets: Financial institutions and large corporations utilize interest rate futures (e.g., Treasury bond futures, Eurodollar futures) to manage the risk of changing interest rates on their borrowing or lending activities. The introduction of financial futures in the 1970s revolutionized risk management beyond just commodities³. Early financial futures, such as those launched in 1972 on foreign currencies and later in 1975 on interest rates, provided new tools for managing financial risks².
• Equity Markets: Investors and portfolio managers use equity index futures (e.g., S&P 500 futures) to hedge against broad market downturns or to gain exposure to market movements without trading individual stocks.
• Speculation: Professional traders and institutional investors engage in speculation by buying or selling futures contracts based on their predictions of future price movements. This activity contributes to market efficiency and liquidity.
• Arbitrage: Opportunities for arbitrage can arise if the futures price deviates significantly from its theoretical fair value, allowing traders to profit from temporary mispricings between the spot and futures markets.

Limitations and Criticisms

While futures contracts offer significant benefits for risk management and price discovery, they also come with limitations and criticisms:

• Leverage and Risk: Futures contracts are highly leveraged instruments, meaning a small price movement can result in a significant profit or loss relative to the initial margin posted. This leverage amplifies both gains and losses, posing substantial risks, especially for inexperienced traders. Losses can exceed the initial investment.
• Complexity: Understanding the nuances of futures pricing, margin calls, delivery procedures, and the specific rules of different exchanges can be complex.
• Basis Risk: Hedging with futures is not always perfect. Basis risk arises when the correlation between the spot price of the underlying asset and the futures price is not exact. This can occur due to differences in grade, location, or time, leading to imperfect hedges.
• Market Manipulation Concerns: Historically, concerns about market manipulation, such as corners or squeezes, have led to regulatory oversight. While regulators like the Commodity Futures Trading Commission (CFTC) work to prevent such activities, they remain a potential risk in less liquid markets¹.
• Speculative Bubbles: Some critics argue that excessive speculation in futures markets can contribute to price bubbles or increased volatility, detaching prices from fundamental supply and demand, particularly in commodity markets.

Futures Contracts vs. Forward Contracts

Futures contracts and forward contracts are both agreements to buy or sell an asset at a predetermined price on a future date. However, key distinctions separate them:

The standardization and exchange-traded nature of futures contracts enhance transparency, liquidity, and reduce counterparty risk compared to their customized, privately negotiated forward counterparts.

FAQs

What is the primary purpose of futures contracts?

The primary purpose of futures contracts is to allow participants to manage price risk (hedging) or to profit from anticipated price movements (speculation). They enable buyers and sellers to lock in a price for an asset that will be delivered or exchanged at a future date.

How do futures contracts reduce risk for businesses?

Businesses use futures contracts for hedging by locking in the price of raw materials they need to purchase or the price of products they plan to sell in the future. This reduces their exposure to unexpected price fluctuations, making their future costs or revenues more predictable.

What is a "margin call" in futures trading?

A margin call occurs when the equity in a trader's margin account falls below the maintenance margin level required by the exchange. This typically happens when the market moves against the trader's position. The trader then receives a request from their broker to deposit additional funds to bring their account back up to the required margin level.

Can individuals trade futures contracts?

Yes, individuals can trade futures contracts through brokerage firms that offer access to futures markets. However, due to the high leverage and potential for significant losses, futures trading is generally considered suitable only for experienced investors who fully understand the risks involved. It requires careful consideration of one's risk management strategy.

What kinds of assets can be traded with futures contracts?

Futures contracts are available for a wide range of underlying assets, including physical commodities (e.g., crude oil, gold, corn), financial instruments (e.g., stock indexes, interest rates, foreign currencies), and even less traditional assets like weather indexes.
