Spot vs futures markets

The spot market is immediate: I buy a barrel of crude oil today, and you deliver it to me today (or within 2–3 business days, depending on location). The spot price is what you pay. The futures market is delayed: I buy a crude oil futures contract today that obligates delivery three months from now at a price set now. The futures price typically differs from the spot price because of storage cost, financing, and time value of money.

Futures contracts are standardized agreements traded on exchanges. A NYMEX crude oil contract represents 1,000 barrels; a gold futures contract represents 100 troy ounces. Each contract specifies: quantity, quality (crude oil API gravity and sulfur content, gold fineness), delivery location (Cushing, Oklahoma for crude; eligible vaults for gold), and delivery month. Standardization creates fungibility—any buyer can trade with any seller; contracts are infinitely divisible. This is why futures are the most liquid markets on Earth.

The key mechanic is margin. To trade futures, you don't pay the full value upfront. Instead, you deposit initial margin—a small percentage (1–3 percent) of the contract value as a good-faith deposit. For crude oil at $85/barrel, the initial margin is roughly $1,500–2,000 per contract (1,000 barrels, so $85,000 notional value). This leverage is the source of both outsized profits and devastating losses. A $5,000 move in crude oil doubles your $2,000 margin deposit—or wipes it out.

Mark-to-market settlement enforces daily accounting. At the end of each trading day, futures are repriced at the settlement price. If you bought crude at $85 and it closes at $86, you pocket $1,000 (1,000 barrels × $1/barrel). This profit is credited to your account. The next day, if crude falls to $84, you lose $2,000. This real-time settlement prevents losses from accumulating invisibly. It's why margin calls can arrive at dawn if prices gap overnight.

If your account falls below the maintenance margin requirement, you receive a margin call—a demand to deposit additional cash. On the NYMEX, this can happen in minutes if crude gaps down 2 percent or more overnight. Failure to meet the call forces liquidation of your position at market prices, potentially locking in losses. During Black Monday (1987) or the 2020 oil crash, margin calls devastated overleveraged traders.

Hedging versus speculation are two sides of the same market. A farmer with 100 acres of wheat is "long" wheat—exposed to price declines. To hedge, the farmer sells futures contracts (short), locking in a harvest price. An oil company with production obligations is long oil; it buys crude futures to hedge output. Conversely, a speculator who owns no oil buys futures purely for profit. Both parties are essential: hedgers provide the demand for insurance; speculators provide the supply, earning risk premiums for bearing commodity price risk.

Delivery is the disciplining force. When a futures contract approaches expiration, it can be settled two ways: financial (cash settlement) or physical (delivery). Most traders close positions before expiration rather than take delivery because physical logistics are expensive and illiquid. However, the threat of delivery keeps futures prices tethered to spot prices. As a contract approaches delivery, the futures-spot spread (basis) compresses toward zero. If futures traded far above spot, any holder could buy spot, sell futures, and pocket an arbitrage gain by tendering at delivery.

Clearing houses (CME Clearing for US exchanges, LME Clearing for metals) guarantee every trade. You don't owe the trader on the other side; you owe the clearing house, and it owes you. This eliminates counterparty risk. If a major trader defaults on a loss, the clearing house absorbs the hit, not innocent traders. This is why the 2008 financial crisis didn't crater commodity markets—futures clearing was rock solid even as Lehman Brothers collapsed.

For beginner investors, the distinction is stark: spot markets are for consumers and commercial hedgers; futures are for informed traders, institutions, and risk managers. Casual retail investors should avoid leverage and understand margin mechanics thoroughly before trading futures. For exposure to commodity prices, ETFs (covered later) are typically safer because they handle margin management internally.
