Physical Commodity Market vs Derivatives Market

The physical commodity market is where actual goods—grain, crude oil, metals, coffee—change hands for immediate delivery. The derivatives market trades contracts whose value depends on those same commodities, without the buyer taking possession. Prices in each market are connected but can diverge, and each serves different needs.

What physical commodity markets are

A physical commodity market deals in the thing itself. A copper mine sells bars of refined copper; a farmer brings wheat to an elevator; an oil well produces crude destined for a refinery. The transaction culminates in possession—the buyer gets the good, the seller gets cash. The price depends on what the good is worth right now: supply in the warehouse, demand from mills and factories, storage costs, spoilage risk, transport distance.

Physical markets are fragmented. Copper trades at different prices in Shanghai, London, and New York, though arbitrage dampens big gaps. A tonne of crude in the North Sea is not identical to WTI crude in Oklahoma; a bushel of hard red winter wheat differs from soft white wheat. Buyers accept delivery terms and the particular grade; sellers price accordingly.

Most physical commodity trading happens “over the counter”—directly between producer and buyer, or through dealers and brokers. A coffee cooperative sells directly to roasters. An aluminum smelter buys from miners or dealers. Prices are often opaque outside major centralized spots like the London Metal Exchange or COMEX.

What derivatives markets are

Derivatives markets trade standardised contracts. A futures contract on crude oil obligates one party to deliver 1,000 barrels at a specified grade and location on a specified date; the buyer contracts to take it. A gold futures contract is for 100 ounces, grade .995 fineness, delivery in New York. An option gives the right, not the obligation, to buy or sell a tonne of copper at a fixed price.

These contracts trade on exchanges—the CME, NYMEX, ICE, LME—where prices are public and transparent. Millions of contracts can turn over in seconds. The buyer of a futures contract never meets the seller; the exchange stands in the middle as counterparty.

Critically, most derivatives contracts never involve physical delivery. A trader buys 10 crude oil futures; weeks later, as the expiration approaches, she sells them back—closing the position and taking a profit or loss on the price move. The crude itself stays in a tank in Texas. The contract is purely financial.

Why prices can diverge

The price of a barrel of crude today (the spot price in the physical market) and the price of a futures contract expiring three months from now are related but distinct.

Spot prices reflect immediate realities: a refinery is shutting down for maintenance, and bidding for crude drops. A pipeline breaks; crude backs up; buyers pay less. A hurricane threatens the Gulf; refiners rush to cover; prices spike.

Futures prices reflect expectations. If traders believe demand will be strong in three months, futures rise even if spot crude is cheap. If a major producer is scheduled to restart a facility, futures may decline. Interest rates matter too—storing crude is costly, and higher rates make it more expensive to finance storage, which can depress futures prices relative to spot.

The difference between spot and futures is called the basis. When futures are higher than spot, the market is in contango. When futures are lower, it’s in backwardation. The basis normally shrinks as the contract nears expiration—the two prices converge.

But large structural shocks can widen the gap. In April 2020, WTI crude futures fell negative (traders paid to take delivery), yet physical crude in some locations stayed positive—a rare, vivid illustration of how disconnected the two markets can temporarily be.

Who uses each market and why

Producers, refiners, and end-users operate primarily in the physical market. A gold mine sells ore. A bakery buys wheat. An airline hedges jet fuel. They need the actual commodity or must deliver what they’ve contracted to produce.

Derivatives markets attract two types of non-commercial users. Hedgers use derivatives to protect against price moves in the physical market they’re exposed to—a refinery buys crude futures to lock in supply costs ahead of a planned increase in production. Speculators (and algorithmic traders) bet on price moves without any intention to take delivery—profiting from directional bets or statistical arbitrage.

Speculators provide liquidity that makes derivatives markets deep and efficient. They also drive prices away from physical fundamentals, sometimes for extended periods. A speculative surge in oil futures can bid up the price despite adequate supply, or a crash can depress it despite strong demand.

How prices feed back

Derivatives prices influence physical prices and vice versa. Commodity producers watch futures prices closely when deciding whether to bring supply forward or hold it in inventory. If three-month copper futures are well above spot, smelters are incentivized to sell; if futures are cheap, they may slow output or store. Buyers do the reverse: cheap futures encourage purchasing ahead of need.

Over time, the two markets converge on a consistent narrative. But in any given moment—when news is still being digested, liquidity is thin in one market, or a major speculator moves—prices can tell different stories. Understanding that distinction is essential for anyone analyzing commodity markets or making physical procurement decisions.
