Brent vs WTI: Key Differences for Commodity Traders

Brent and WTI defined Brent Crude and West Texas Intermediate (WTI) are the two most widely quoted crude oil price benchmarks in the world. Brent is extracted from North Sea oil fields and serves as the global pricing reference for approximately 70–75% of internationally traded crude. WTI is a US-produced crude that serves as the primary benchmark for American oil markets. Both are classified as “light sweet” crudes, but they differ in exact API gravity, sulphur content, delivery infrastructure, and trading venue.

Origin and Geology

WTI: West Texas Intermediate

West Texas Intermediate is produced from oil fields in Texas, North Dakota, and other parts of the continental United States. It’s extracted onshore, primarily from the Permian Basin in West Texas — one of the world’s most productive oil-producing regions.

The “Intermediate” in its name is a legacy classification referring to its density grade relative to other crudes of its era, not to any current ranking system. WTI is now classified as a light, sweet crude — terms defined by its API gravity and sulphur content, which we cover in the next section.

Brent Crude

Brent Crude originally referred to oil extracted from the Brent oil field in the North Sea, operated by Shell from the 1970s onward. As that specific field’s production declined, the “Brent” price benchmark evolved to represent a basket of North Sea crudes: Brent, Forties, Oseberg, Ekofisk, and Troll — collectively known as BFOET or informally as “Dated Brent.”

North Sea production is offshore. Platforms extract crude from beneath the seabed, and it’s transported to shore via pipelines or shuttle tankers. The offshore production and export-oriented geography of Brent crude is central to understanding why it became a global benchmark rather than a regional one.

API Gravity and Sulphur Content

These two measurements determine how valuable a crude is to refiners — and why both WTI and Brent command premium prices over heavier, sourer alternatives.

API Gravity

API gravity is the American Petroleum Institute’s measure of crude oil density relative to water. Higher API gravity = lighter oil = more valuable to refiners because lighter oil yields more of the high-demand products (gasoline, jet fuel, diesel) when processed.

• WTI: API gravity of 39.6° — very light
• Brent: API gravity of 38.3° — light, but marginally denser than WTI

By comparison:

• Heavy crude (e.g., Venezuelan Merey): API gravity of ~16°
• Extra-heavy crude (Canadian oil sands): API gravity below 10°

Both WTI and Brent qualify as “light” crude by the industry standard threshold of 31.1° API. The roughly 1.3° difference between them is meaningful to refiners calibrating their crude slates but doesn’t dramatically change the refining economics.

Sulphur Content

Sulphur content (also called “sweetness”) determines refining complexity. Low-sulphur crude is “sweet”; high-sulphur crude is “sour.” Refiners prefer sweet crude because they don’t need to run expensive desulphurisation units to meet fuel sulphur standards.

• WTI: sulphur content of approximately 0.24% by weight — very sweet
• Brent: sulphur content of approximately 0.37–0.40% by weight — sweet, but marginally more sulphurous than WTI

The industry threshold: less than 0.5% sulphur = sweet; above 0.5% = sour. Both benchmarks are firmly in sweet territory. The difference between them is small but consistent — WTI is slightly sweeter, meaning slightly lower refining cost per barrel.

Characteristic	WTI	Brent
API Gravity	39.6°	38.3°
Sulphur Content	~0.24%	~0.37–0.40%
Classification	Light, sweet	Light, sweet
Production location	Onshore, US	Offshore, North Sea

Delivery Points and Physical Infrastructure

The physical delivery point of each crude is one of the most commercially important differences between the two benchmarks — and the source of significant price distortions at various points in history.

WTI: Cushing, Oklahoma

WTI’s futures contract specifies delivery at Cushing, Oklahoma — a landlocked pipeline hub in the US midcontinent nicknamed the “Pipeline Crossroads of the World.” Cushing has approximately 90 million barrels of storage capacity and sits at the junction of dozens of pipeline systems.

The landlocked nature of Cushing creates a significant limitation: crude can only move in or out via pipeline. When Cushing storage fills up — as it did during the COVID-19 demand collapse in April 2020 — WTI prices can detach dramatically from global markets. On April 20, 2020, the May 2020 WTI futures contract briefly traded at -$37.63 per barrel — negative pricing — because traders holding contracts had no physical storage available and no way to take delivery.

This Cushing dynamic means WTI prices can sometimes diverge substantially from global supply-demand fundamentals. The Brent-WTI spread widened to over $25/barrel in 2011–2013 partly because US shale production was surging into Cushing faster than pipeline capacity could move it out.

Brent: North Sea / Waterborne

Brent crude, being produced offshore and loaded onto tankers, is waterborne — it can be shipped anywhere in the world from the point of extraction. This gives Brent pricing a global character that WTI’s landlocked delivery point cannot fully match.

A cargo of North Sea Brent can head to Rotterdam, the US Gulf Coast, China, or India. The price reflects global supply and demand rather than localised infrastructure constraints. This is a key reason Brent became the dominant global benchmark.

Exchange Specifications: NYMEX vs ICE

WTI: NYMEX

WTI crude trades on the New York Mercantile Exchange (NYMEX), which is part of the CME Group. The standard futures contract covers 1,000 barrels of WTI crude, priced in US dollars per barrel.

• Contract ticker: CL
• Delivery: physical delivery at Cushing, Oklahoma
• Contract months: monthly out several years
• Trading: electronic via CME Globex; open-outcry trading reduced in recent years
• Settlement: physical (but most contracts are rolled or closed before delivery)

Brent: ICE

Brent crude trades on the Intercontinental Exchange (ICE), primarily on ICE Futures Europe in London. The standard contract also covers 1,000 barrels, priced in US dollars per barrel.

• Contract ticker: BZ (Brent; also commonly quoted as CO on Bloomberg systems)
• Settlement: cash settlement against Dated Brent — not physical delivery of specific barrels
• Contract months: monthly out several years
• Trading: primarily electronic via ICE platform

The cash settlement structure of the Brent contract is an important difference. WTI settles to physical delivery of crude at Cushing. Brent settles to a cash payment based on the Dated Brent assessment published by Platts (now S&P Global Commodity Insights). This makes the Brent futures market somewhat more liquid and less exposed to physical infrastructure constraints than WTI.

Global Benchmark Roles

Brent: The Global Oil Price

Brent crude prices approximately 70–75% of globally traded crude oil. When an oil ministry in Saudi Arabia, Iraq, or Nigeria sets the price of its crude for customers, it typically quotes a differential to Brent. When news reports say “oil prices rose today,” they almost always mean the Brent price.

The reasons for Brent’s dominance are geographic and historical:

• North Sea crude is waterborne and genuinely internationally traded
• Brent established itself as a benchmark before WTI shale disruption
• Middle Eastern, African, and North Sea producers all set official selling prices (OSPs) as differentials to Brent

WTI: The Americas Benchmark

WTI remains the primary price reference for US domestic crude markets and for Latin American crude trade. Mexican Maya crude, Canadian WCS, and various US regional grades are all priced as differentials to WTI.

After the US crude export ban was lifted in December 2015, US WTI crude began flowing into international markets, and WTI’s global relevance increased. But Brent remains the dominant global benchmark.

The Brent-WTI Price Spread

The Brent-WTI spread — the difference in price between the two benchmarks — is widely tracked as a signal of market conditions.

Historically, WTI traded at a slight premium to Brent because it’s marginally lighter and sweeter. From 2011 to roughly 2019, this relationship inverted dramatically: the US shale revolution flooded Cushing with crude, creating a persistent infrastructure bottleneck and pushing WTI to a $5–25/barrel discount to Brent.

As US pipeline capacity expanded and crude export infrastructure built out along the Gulf Coast, the spread narrowed. In recent years (2022–2024), Brent has typically traded at a $3–7/barrel premium to WTI under normal market conditions — though geopolitical events and infrastructure constraints can push the spread in either direction rapidly.

Traders, refiners, and logistics professionals watch this spread closely. A widening Brent premium signals either US infrastructure constraints or global supply tightness relative to the US domestic market. A narrowing spread often reflects increased US crude exports reducing the Cushing glut.

Other Crude Benchmarks

Brent and WTI are not the only crude benchmarks, though they are by far the most quoted. Other significant reference crudes include:

• Dubai/Oman: The primary benchmark for Middle Eastern crude sold into Asia. Priced in USD/barrel on the Dubai Mercantile Exchange (DME).
• ESPO (East Siberia–Pacific Ocean): Russian crude exported to Asia via pipeline; priced at a discount or premium to Dubai.
• Bonny Light: A Nigerian light sweet crude; priced as a differential to Brent.
• Mexican Maya: A heavy sour Mexican crude; priced as a differential to WTI.

Understanding which benchmark applies to a given crude trade requires knowing the origin and destination of the cargo.

Frequently Asked Questions

Why does Brent price more of the world’s oil than WTI if WTI is slightly higher quality?

Brent’s dominance is historical and geographic. North Sea crude was internationally traded from the 1970s and became the reference price for oil flowing between Europe, the Middle East, and Africa before US shale production transformed the WTI market. Once benchmark relationships are established in long-term supply contracts and pricing formulas, they’re slow to change.

Can a US refiner choose to buy crude priced against Brent instead of WTI?

Yes. Refiners buy from multiple sources. A US Gulf Coast refinery might import Saudi crude priced against Brent while also buying Texas crude priced against WTI in the same week. Refiners are continuously optimising their “crude slate” — the mix of crude grades — based on refinery configuration and relative pricing.

What does the WTI-Brent spread tell a shipping professional?

A wide Brent premium to WTI makes US crude exports more competitive internationally — buyers in Asia and Europe compare landed WTI (WTI price + freight) against Brent-based alternatives. When WTI is cheap relative to Brent, US export volumes tend to rise, increasing VLCC bookings from US Gulf Coast ports.

Why did WTI go negative in April 2020?

Physical delivery constraints at Cushing, Oklahoma combined with a complete collapse in crude demand during COVID lockdowns. Traders holding May 2020 futures contracts could not accept physical delivery of crude — there was no empty storage — and could not easily exit contracts in an illiquid market. They sold at any price to avoid taking delivery, driving the May contract briefly to -$37.63/barrel.

How often does the Brent price change?

Brent futures trade nearly 24 hours a day on ICE. The “spot” price you see on a given day is the front-month futures price. Physical “Dated Brent” — the price for cargoes loading in a specific 10–25 day window — is assessed by S&P Global Commodity Insights (formerly Platts) from actual physical market transactions.

Are Brent and WTI the same chemical product?

No, but they’re both light sweet crudes and produce broadly similar product yields when refined. WTI is slightly lighter (higher API) and sweeter (lower sulphur), which gives it a marginal quality advantage. In practice, most modern refineries can process both without major reconfiguration.

Key Takeaways

• Brent and WTI are both light, sweet crudes but differ in API gravity (WTI 39.6° vs Brent 38.3°) and sulphur content (WTI 0.24% vs Brent ~0.37–0.40%).
• WTI delivers physically at Cushing, Oklahoma — a landlocked pipeline hub; Brent is waterborne, which makes it a more genuinely global price signal.
• Brent trades on ICE Futures Europe (cash-settled); WTI trades on NYMEX/CME Group (physically settled).
• Brent prices approximately 70–75% of the world’s internationally traded crude oil; WTI is the dominant benchmark for US domestic markets and the Americas.
• The Brent-WTI spread — normally $3–7/barrel in Brent’s favour — reflects infrastructure constraints, US export capacity, and relative supply-demand conditions between markets.
• When crude export routes from the US Gulf Coast are constrained, WTI prices discount more heavily relative to Brent — which can widen shipping arbitrage opportunities for tanker operators.
