Location Spread (Commodities)

A location spread is the price difference between futures contracts for the same commodity at different delivery hubs, determined by the cost and logistics of moving that commodity between locations. It is one of the most stable and predictable arbitrage opportunities in commodity markets.

Physical transport costs anchor the spread

Every commodity exists in space. Crude oil pumped from North Dakota has to reach coastal refineries. Corn harvested in Iowa must feed poultry operations in Georgia. That movement costs money—trucking, rail, shipping, pipeline tolls—and that cost shows up directly in the futures curve.

When you compare the futures price for oil at Cushing, Oklahoma (the traditional delivery point for WTI crude) to the price at Houston, the gap reflects the ~300-mile pipeline haul between them. In normal market conditions, you can nearly predict that spread: it will equal the cost of transportation plus a small markup for logistics operators and risk. If the spread widens dramatically—say, Houston oil trades far higher than Cushing—an astute trader can lease a pipeline, pump oil from Cushing to Houston, and pocket the difference. That arbitrage activity pulls the spread back to equilibrium.

The same logic holds across the commodity world. Gold futures at COMEX in New York and gold at the Shanghai Gold Exchange differ by shipping costs, insurance, and the time value of money. Agricultural contracts at the Chicago Board of Trade for Kansas City wheat diverge from Minneapolis spring wheat by truck distance and seasonal storage availability.

Storage and infrastructure create regional variation

Location spreads widen or narrow based on the capacity and congestion of the route between two points. When a pipeline ruptures or a port strikes, the spread can spike dramatically—suddenly the alternate route costs more, or capacity pinches entirely. Similarly, if warehouse space is abundant in one location and scarce in another, traders will pay more to take delivery where inventory sits high, effectively broadening the spread.

The Cushing oil hub became the standard US crude delivery point not by decree but by infrastructure: rail lines converged there, storage tanks filled it, and pipeline networks radiated outward. Its role meant its futures contract was most liquid and most heavily used for hedging. As shale production shifted US oil toward the Gulf Coast, spreads between Cushing and Houston gradually widened—the market recognizing that actual commercial flows favored coastal delivery.

Spreads flatten in distressed market conditions

During a physical shortage—a refinery explosion, a freak storm that closes ports, a geopolitical flare-up that cuts off supply—the location spread can compress to nearly zero. When buyers desperately need oil now at any hub, the premium for location evaporates. They will pay the same price at Cushing as Houston and absorb the transport cost themselves.

Conversely, in periods of genuine oversupply, storage fills and spreads can invert: a location with no available tank space might see futures trade at a discount to a nearby hub with storage. The inversion signals that buyers have no reason to rush. They can store the commodity locally, and the cost of that storage now sets the location spread.

Spreads differ systematically by commodity type

Crude oil and metals, highly transportable, tend to have tight and predictable location spreads. Shipping a ton of gold from New York to London and back costs a few cents per ounce—a small percentage of the commodity’s value. Perishable agricultural goods, by contrast, show wider and more volatile location spreads because some routes (air freight) are extremely expensive, and spoilage risk rises with transport time.

Natural gas location spreads are particularly large and persistent because gas pipelines are expensive to build and inflexible once built. Gas prices at the Henry Hub in Louisiana and at Permian Basin processing plants can diverge substantially and durably because the infrastructure connecting them is fixed and expensive.

Reading the spread tells you about market structure

An experienced commodity trader reads location spreads as a diagnosis of market health. A tight spread suggests efficient logistics, ample transportation capacity, and orderly markets. A widening spread can signal emerging bottlenecks—a full storage tank, a broken railcar route—before any physical shortage becomes obvious. In that sense, location spreads are early indicators of supply friction, and traders who monitor them closely often spot dislocations before they hit the headlines.

The spread also reflects storage and carry costs. In a contango market, where future prices exceed spot prices, the location spread typically widens because the cost of carry (storage, insurance, financing) compounds over the longer route. If you have to store oil for weeks in transit, that cost grows with distance, and the spread reflects it.

Arbitrage keeps spreads rational

If location spreads ever drift far from physical transport costs—if Houston crude was $5 cheaper than Cushing crude, for example—a trader would lease a truck or pipeline, move the barrel, and lock in a riskless profit. That trade, repeated by many investors, would push spreads back into line. The existence of willing arbitrageurs means location spreads are among the most stable and least prone to panic widening in all of commodities.

The flip side is that location spreads offer little free return. By the time you account for transport costs, storage, insurance, and financing, the profit margin from a location arbitrage is razor-thin. But that thinness is precisely what makes them attractive to automated traders and large commodity merchants operating at scale. Every dollar saved in logistics flows straight to the bottom line.
