Brent vs. WTI

01Two Benchmarks, One Commodity

Walk into any trading room that handles crude oil and two numbers dominate the screens: Brent and WTI. Both track the price of a barrel of crude oil. Both move, broadly, in the same direction for the same broad reasons — supply, demand, geopolitics, the dollar. Yet they are not the same price, they never trade at exactly the same level, and the gap between them — the spread — shifts constantly, carrying its own signal about where oil is moving, where it is bottlenecked, and what markets think about supply in different parts of the world.²³

Understanding the two benchmarks starts with understanding what they actually measure.

Brent crude takes its name from a field in the North Sea. The Brent benchmark has long since outgrown that single field and now reflects a basket of North Sea grades — Brent, Forties, Oseberg, Ekofisk and Troll, collectively known as BFOET. Because North Sea crude is loaded onto tankers offshore, Brent is priced on a dated basis: a physical cargo, deliverable on a specific date. That physical anchor makes it a natural reference for seaborne trade. The majority of the world's crude oil — the volumes moving out of West Africa, the Middle East, the Mediterranean, Russia and the North Sea itself — is priced against Brent. By most estimates Brent underpins somewhere around three quarters of global crude contracts.¹

West Texas Intermediate, or WTI, is a light, sweet crude produced primarily in Texas and the broader Permian Basin region of the United States. Its pricing hub is Cushing, Oklahoma — a landlocked tank-farm and pipeline junction sometimes called "the pipeline crossroads of the world." Because WTI settles at Cushing, its price reflects not just the quality of the crude but the logistics at that specific inland point: how full the tanks are, how much pipeline capacity is available to move oil in and out, what is happening in the US Gulf Coast refinery complex downstream.

02Same Direction, Different Levels

Because both benchmarks ultimately track the global crude market, they tend to move together in response to the same macro forces — OPEC+ production decisions, economic growth expectations, dollar strength, inventory data. When demand surges or supply tightens, both benchmarks rise. When a recession looms or barrels flood the market, both fall. The correlation is high.

But the spread between them fluctuates, and those fluctuations carry real information.

Historically, Brent has often traded at a premium to WTI — meaning a barrel of Brent costs more than a barrel of WTI. Several forces drive this. Brent's seaborne nature makes it genuinely global: it reflects world supply and demand without the distortions of any single inland logistics system. WTI, by contrast, can become disconnected from global markets when Cushing fills up or pipeline capacity from the Permian to the Gulf Coast is insufficient. When US shale production surged faster than export and pipeline infrastructure could handle it, WTI sometimes traded at a pronounced discount to Brent — a structural signal of local oversupply rather than global glut. Over time, as the US built out export terminals and pipeline capacity, that discount narrowed.

The spread also responds to quality differences. Both Brent and WTI are light, sweet crudes — relatively low in density and sulfur, making them cheaper to refine into gasoline, diesel and jet fuel than heavier, sourer grades. WTI is slightly lighter and sweeter than Brent. In theory, its refining advantage should command a premium. That it often doesn't reflects the persistent weight of logistics and geography on pricing.

Geopolitical events tend to move the spread in predictable directions. A supply disruption in the Middle East or North Africa tightens Brent more than WTI, since those barrels price against Brent. US-specific events — a hurricane hitting Gulf Coast refineries, a pipeline outage near Cushing, a surge in shale output — affect WTI more acutely. Traders watch the spread as a live, real-time measure of these regional pressures.

Over time, as the US built out export terminals and pipeline capacity, that discount narrowed.

03What the Spread Signals

Think of the Brent-WTI spread as a diagnostic reading rather than just an arithmetic difference. A wide Brent premium often points to tightness in internationally traded crude while US supply remains ample. A narrow spread — or the relatively rare occasions when WTI moves to a premium — suggests strong US refinery demand, constrained domestic supply, or that export flows are efficiently arbitraging the gap between markets. When the spread blows out sharply, it typically flags a physical bottleneck, a geopolitical shock, or a sudden shift in regional inventory that the two markets are absorbing at different speeds.

For producers, refiners and traders, neither benchmark is "better." A West African producer selling into Asia quotes against Brent because that is the convention and the contract. A US shale producer selling domestic crude works from WTI. Refiners on the Gulf Coast watch both, because their feedstock costs and their product sales may reference different benchmarks.

Two prices, one market — but the distance between them is never noise. Every basis point of the spread is a molecule of information about where oil is, where it needs to go, and what it costs to get it there.
