How Crude Oil Prices Are Set: WTI vs Brent Benchmarks
When energy traders and investors talk about the crude oil price, they are almost always referring to one of two global benchmark grades: West Texas Intermediate (WTI) or Brent crude. These two benchmarks dominate global oil pricing, but they measure different things, trade in different places, and diverge in price for reasons that are worth understanding. Knowing how each benchmark is set — and why they sometimes diverge significantly — is foundational for anyone who follows energy markets.
What is West Texas Intermediate (WTI)?
West Texas Intermediate is a grade of crude oil produced primarily in the Permian Basin and other inland U.S. oil-producing regions. It is classified as light and sweet, meaning it has a low density and low sulfur content, which makes it relatively easy and inexpensive to refine into gasoline and other light petroleum products. WTI futures are traded on the New York Mercantile Exchange (NYMEX), and the benchmark price refers specifically to delivery at Cushing, Oklahoma — a major oil storage and pipeline junction point. Because Cushing is landlocked, WTI prices can diverge from global markets when storage at Cushing fills up or when pipeline capacity constrains flows. This happened dramatically in April 2020, when WTI futures briefly went negative as storage overflowed during pandemic demand collapse.
What is Brent Crude and Why Does It Dominate?
Brent crude originates from the North Sea and is named for the Brent oil field discovered off the Scottish coast in the 1970s. It is technically a blend of crude oils from multiple North Sea fields, and is also light and sweet, though slightly heavier and more sulfurous than WTI. Brent is traded on the Intercontinental Exchange (ICE) and serves as the pricing reference for approximately two-thirds of the world's internationally traded crude oil contracts. Its offshore production point makes it less susceptible to the pipeline and storage constraints that affect WTI pricing. The Brent price is considered a better reflection of global supply and demand conditions, which is why it commands a premium over WTI in most market environments and is the benchmark most frequently cited in international energy news.
Key Factors That Move Crude Oil Prices
Both benchmarks respond to the same underlying supply and demand forces, though with different sensitivities. OPEC+ production decisions — coordinated output cuts or increases among the world's major producing nations — are the single most powerful near-term driver of global oil prices. When OPEC+ announces unexpected production cuts, Brent prices typically jump within hours. Demand signals from major consuming economies — particularly China, the United States, and Europe — also drive prices. A stronger-than-expected Chinese industrial output report tends to push crude prices upward, as China is the world's largest oil importer. Geopolitical disruptions — conflicts in oil-producing regions, sanctions on major exporters, or tensions in shipping chokepoints like the Strait of Hormuz — introduce supply risk premiums that can persist for months.
How the Spread Between WTI and Brent Changes
The price spread between WTI and Brent — typically called the Brent-WTI spread — varies over time and reflects specific structural differences between the two markets. When U.S. shale production surges and Cushing storage fills, WTI can trade at a significant discount to Brent. When U.S. export infrastructure is strong and global demand is pulling American crude onto tankers, the spread narrows. During periods of heightened geopolitical risk in regions that supply Brent-priced crude — Middle East, North Sea, West Africa — Brent commands a larger premium. Tracking the spread is itself a useful indicator for energy traders, because a widening spread often signals specific structural conditions in U.S. oil markets.
