Brent Crude vs WTI: What Is the Difference and Why Does It Matter?

Two Benchmarks, One Global Market

When you hear that "oil prices rose today," the question immediately arises: which oil? Crude oil is not a single uniform commodity. It varies in density (measured as API gravity) and sulphur content, and these physical characteristics determine how easily it can be refined into valuable products like gasoline, diesel, and jet fuel. Different grades of crude oil trade at different prices, and the global oil market uses two primary benchmark prices to anchor these trades: Brent Crude and West Texas Intermediate (WTI).

Together, Brent and WTI serve as the reference prices for the vast majority of global oil contracts. Understanding what they are, where they come from, and why they sometimes diverge is essential for interpreting oil market news — and for understanding the price data displayed on OilCrisisTracker.com.

What Is Brent Crude?

Brent Crude is a blend of crude oil produced from several oil fields in the North Sea, primarily the Brent, Forties, Oseberg, Ekofisk, and Troll fields (collectively known as the BFOET blend). The name "Brent" comes from the original Brent oil field, which was discovered by Shell in 1971 and named after the Brent goose.

Brent is classified as a "light sweet" crude, meaning it has a relatively low density (API gravity of approximately 38 degrees) and low sulphur content (around 0.37 percent). These characteristics make it relatively easy to refine into high-value products, which is one reason it commands a premium over heavier, more sulphurous grades.

Brent is the world's dominant oil price benchmark. Approximately 70 to 80 percent of globally traded crude oil is priced relative to Brent. This includes most Middle Eastern, African, and European crude oil exports. When news reports refer to "the oil price," they are most commonly referring to Brent.

Brent futures are traded on the Intercontinental Exchange (ICE) in London, under the ticker symbol BZ=F. The futures contract specifies delivery of crude oil at Sullom Voe terminal in the Shetland Islands, Scotland.

What Is WTI?

West Texas Intermediate (WTI) is a grade of crude oil produced primarily in the Permian Basin and other oil-producing regions of Texas and the surrounding US states. It is also classified as light sweet crude, with an API gravity of approximately 39.6 degrees and sulphur content of around 0.24 percent — making it slightly lighter and sweeter than Brent.

WTI is the primary benchmark for US domestic oil markets. It is traded on the New York Mercantile Exchange (NYMEX) under the ticker symbol CL=F. The futures contract specifies delivery at Cushing, Oklahoma — a major oil storage and pipeline hub in the central United States known as the "Pipeline Crossroads of the World."

WTI is the benchmark for approximately 20 to 30 percent of globally traded crude oil, primarily US domestic production and some Canadian and Latin American grades. US shale oil production — which has grown dramatically since 2010 and made the United States the world's largest oil producer — is priced primarily against WTI.

The Brent-WTI Spread

Brent and WTI prices are closely correlated but rarely identical. The difference between them — known as the Brent-WTI spread — fluctuates based on supply and demand conditions in each market, transportation costs, and geopolitical factors.

Historically, WTI traded at a slight premium to Brent, reflecting its marginally higher quality (lower sulphur content). However, the US shale revolution of the 2010s dramatically changed this relationship. The rapid growth of US domestic production created a glut of oil at Cushing, Oklahoma — the WTI delivery point — which pushed WTI prices below Brent for most of the period from 2011 to 2020. At times, the spread reached $20 to $25 per barrel, with Brent trading significantly above WTI.

The 2026 Iran conflict has created an unusual spread dynamic. Because Brent is more directly affected by Middle Eastern supply disruptions (as it is the benchmark for Persian Gulf crude), Brent has risen more sharply than WTI in response to the Hormuz crisis. WTI, which reflects US domestic production that is largely insulated from Hormuz disruptions, has risen less dramatically. This has widened the Brent-WTI spread to levels not seen since the early 2010s.

Why Brent Is More Globally Relevant

For understanding the global impact of the 2026 energy crisis, Brent is the more relevant benchmark. This is because most of the world's oil trade — including all Persian Gulf exports, African exports, and North Sea exports — is priced against Brent. When Middle Eastern supply is disrupted, Brent prices respond most directly.

WTI is more relevant for understanding the US domestic market. Because the United States is now a net oil exporter (thanks to shale production), it is less directly affected by Hormuz disruptions than it was in previous decades. US refiners can substitute domestic WTI crude for imported Brent crude to some degree, which is one reason US gasoline prices have risen less sharply than European and Asian fuel prices during the 2026 crisis.

However, the global oil market is interconnected enough that a major Brent price increase will eventually pull WTI prices higher as well. US oil producers benefit from higher global prices and increase production, while US refiners face higher costs for any imported crude they continue to use. The net effect is that US consumers are not insulated from global oil price shocks — they are merely somewhat buffered compared to countries that are entirely import-dependent.

Other Important Oil Benchmarks

Beyond Brent and WTI, several other oil benchmarks are important in specific regional markets. Dubai Crude (also known as Dubai/Oman) is the primary benchmark for Middle Eastern crude sold to Asian buyers. OPEC's basket price is a weighted average of the prices of crude oils produced by OPEC member states. Russia's Urals blend is the primary benchmark for Russian crude exports.

The 2026 crisis has created significant divergences between these benchmarks. Middle Eastern grades that would normally transit the Strait of Hormuz are trading at discounts to Brent because buyers are uncertain about delivery reliability. Russian Urals, already trading at a discount due to Western sanctions, has seen its discount widen further as some buyers seek to reduce their exposure to politically sensitive supply chains.

How OilCrisisTracker Uses These Benchmarks

OilCrisisTracker.com displays both Brent (BZ=F) and WTI (CL=F) prices on the homepage and throughout the site. Brent is displayed first and used as the primary reference for the Global Crisis Severity Index, as it is the more globally representative benchmark. WTI is displayed alongside Brent to allow users to monitor the spread and understand the differential impact on US versus global markets.

Both prices are sourced from Yahoo Finance's real-time futures data and are updated hourly during market trading hours. The percentage change displayed is calculated against the previous trading day's closing price, allowing users to track daily movements in both benchmarks.
