12.1 Forward and Futures Contracts

Forward and Futures Contracts

Forward and futures contracts let people lock in prices for future transactions. These agreements help businesses manage risk and allow traders to profit from price movements. Forwards are customized deals between two parties, while futures are standardized and traded on exchanges. Both can involve various assets like commodities or currencies, with different settlement methods and trading mechanics.

Defining Forward and Futures Contracts

A forward contract is a customized agreement between two parties to buy or sell an asset at a specified price on a future date. The terms (quantity, price, settlement date) are privately negotiated between buyer and seller. For example, a farmer might agree to sell 1,000 bushels of wheat to a baker at $5 per bushel in 6 months. Both sides know exactly what they're getting and when.

A futures contract does the same thing conceptually, but it's standardized and traded on organized exchanges like the Chicago Mercantile Exchange (CME) or the Intercontinental Exchange (ICE). Contract sizes, expiration dates, and delivery terms are all predetermined by the exchange. A gold futures contract on COMEX, for instance, represents exactly 100 troy ounces of gold with specific delivery dates.

The critical feature of both: they create an obligation to complete the transaction at the agreed-upon price, regardless of where the market price ends up at expiration. If you've locked in a price and the market moves against you, you still have to honor the contract.

Underlying Assets and Settlement

Forward and futures contracts can be written on a wide range of underlying assets:

• Commodities: crude oil, precious metals, agricultural products
• Currencies: foreign exchange pairs (EUR/USD, GBP/JPY, etc.)
• Interest rates: bonds, treasury bills
• Stock indices: S&P 500, Dow Jones Industrial Average

Settlement works differently depending on the contract type. Forward contracts are typically settled by physical delivery, meaning the buyer actually takes possession of the asset and the seller receives payment at the agreed price.

Futures contracts, by contrast, are usually settled in one of two ways:

• Cash settlement: the two parties exchange the difference between the contract price and the market price at expiration. No physical asset changes hands.
• Closing out: the trader enters an offsetting trade before expiration (selling a long position or buying back a short position), effectively canceling the obligation.

Most futures traders close out their positions well before expiration. Very few actually want 5,000 bushels of corn delivered to their door.

Mechanics of Trading

Over-the-Counter vs. Exchange-Traded

Forward contracts trade over-the-counter (OTC), meaning directly between two parties, often with a financial institution acting as intermediary. Because the terms are fully customizable, forwards work well for tailored risk management. A company might enter into a forward contract with a bank to buy €1 million at a fixed exchange rate in 3 months, with terms shaped to match its exact needs.

Futures contracts trade on organized exchanges. Buyers and sellers place orders through brokers, specifying the contract type, quantity, and desired price. The exchange matches orders and clears trades through a clearinghouse.

The clearinghouse is what makes futures fundamentally different from forwards in terms of risk. It inserts itself as the counterparty to both sides of every transaction. So the buyer's contract is technically with the clearinghouse, and so is the seller's. This structure dramatically reduces counterparty risk (the chance that the other side defaults), which is a real concern with OTC forwards where you're relying on the other party's creditworthiness.

Margin Requirements and Mark-to-Market

Futures trading uses a margin system to manage risk. Here's how it works:

1. Initial margin: When you open a futures position, you deposit a percentage of the contract's total value (usually 5-10%). This acts as a good-faith deposit and protects against default. You're not paying for the full contract upfront, which is why futures are inherently leveraged.

2. Maintenance margin: This is the minimum balance you must keep in your margin account. It's set below the initial margin level.

3. Margin calls: If losses push your account balance below the maintenance margin, you receive a margin call requiring you to deposit additional funds to bring the account back up to the initial margin level. Fail to meet the call, and your position gets liquidated.

4. Mark-to-market (daily settlement): At the end of each trading day, gains and losses are calculated and settled. If you bought a crude oil futures contract and the price rose today, the gain gets credited to your margin account. If the price fell, the loss gets deducted. This daily settlement prevents losses from accumulating unchecked.

This mark-to-market process is a key distinction from forwards, where gains and losses typically aren't realized until the contract's expiration date.

Pricing and Valuation

Cost of Carry and Convenience Yield

The price of a forward or futures contract reflects the current spot price of the underlying asset, adjusted for two main factors:

Cost of carry includes all the expenses of holding the underlying asset until the contract expires:

• Storage costs for commodities (warehousing, security)
• Insurance to protect against loss or damage
• Financing costs (the interest you'd pay or forgo while holding the asset)

Convenience yield captures the benefit of physically holding the asset rather than just owning a contract for future delivery. This matters most for commodities. An oil refinery, for example, values having physical crude oil on hand to ensure continuous production and meet sudden demand. That benefit of physical possession is the convenience yield, and it effectively reduces the forward price because holding the asset already provides value.

Pricing Formula and Contract Value

The relationship between the forward/futures price and the spot price is described by:

$F = S \times e^{(r - q)T}$

Where:

• $F$ = forward/futures price
• $S$ = current spot price
• $r$ = risk-free interest rate (representing financing cost)
• $q$ = convenience yield
• $T$ = time to expiration (in years)
• $e$ = the base of the natural logarithm (continuous compounding)

The intuition here: the forward price should equal the spot price grown at the net cost of carry. If it costs you more to finance and store the asset (high $r$) than you benefit from holding it (low $q$), the forward price will be above the spot price. If convenience yield is high relative to financing costs, the forward price can actually be below the spot price.

At initiation, the value of a forward or futures contract is typically zero. The contract price is set so that neither party has an advantage at the start. As market conditions shift, the contract gains value for one party and loses value for the other. In futures markets, these value changes flow through the margin account daily via mark-to-market.

Applications in Hedging vs. Speculation

Hedging with Forward and Futures Contracts

Hedging means using forwards or futures to reduce or eliminate the risk of adverse price movements in a position you already hold (or plan to take).

A short hedge involves selling futures to protect against falling prices on an asset you own or plan to sell. A corn farmer, for example, sells corn futures to lock in a price for the upcoming harvest. If corn prices drop before harvest, the loss on the physical corn is offset by gains on the short futures position.

A long hedge involves buying futures to protect against rising prices on an asset you plan to purchase. An airline might buy jet fuel futures to lock in fuel costs for future flights. If fuel prices spike, the higher cost at the pump is offset by gains on the long futures position.

No hedge is perfect, though. The effectiveness depends on how closely the futures contract's price movements track the actual asset being hedged. The hedge ratio measures how many contracts you need to properly offset the risk of your underlying position. When the asset being hedged doesn't perfectly match the futures contract (say, hedging jet fuel with crude oil futures), you get basis risk, which is the risk that the two prices don't move in perfect lockstep.

Speculation with Forward and Futures Contracts

Speculation means using forwards or futures to profit from expected price movements without necessarily having any underlying exposure to the asset.

• Long position (buying contracts): You profit if prices rise. A trader might buy gold futures expecting the price to climb due to geopolitical tensions.
• Short position (selling contracts): You profit if prices fall. A trader might sell crude oil futures anticipating slowing global growth and reduced demand.

Speculators serve an important market function. They provide liquidity (making it easier for hedgers to find counterparties) and contribute to price discovery (helping markets reflect all available information about future prices). They're willing to absorb the risk that hedgers want to shed.

The danger for speculators is leverage. Because futures require only a small initial margin relative to the contract's full value, both gains and losses are amplified. If you control a position with 10x leverage and the price moves against you by 10%, you lose 100% of your invested capital. Leverage is a double-edged sword: it magnifies profits when you're right and magnifies losses just as aggressively when you're wrong.
