Oil WTI vs Brent Spread

Understanding the WTI vs Brent Spread

The WTI–Brent spread is the price gap between the two main global crude oil benchmarks, and the math is about as simple as it gets: Spread = Brent − WTI (in USD per barrel). WTI (West Texas Intermediate) is delivered at the Cushing, Oklahoma storage hub. It is a light, sweet crude with API gravity around 39.6° and sulfur content near 0.24%. Brent is a blend of crudes from North Sea fields (Brent, Forties, Oseberg, Ekofisk, Troll), with API gravity around 38° and sulfur near 0.37%. Both are light and sweet, which makes them well suited to gasoline and diesel refining.

Historically the spread swings between 0 and 5 USD/barrel in Brent's favor. WTI sat at a structural discount from 2011 to 2015, the result of the US crude export ban (lifted in December 2015) on top of the shale boom that flooded Cushing with landlocked production. These days the spread mostly comes down to transport logistics, refinery demand on each coast, the geopolitical risk premium (the Middle East, Russia, Houthi attacks on the Red Sea), and OPEC+ output decisions. Futures trade on CME NYMEX (CL ticker for WTI) and on ICE Europe (B ticker for Brent), where the monthly contract rolls drive the contango and backwardation dynamics.

Applications

Refiners lean on the spread to optimize where they source crude. US Gulf Coast refineries can run more WTI when it trades cheap to Brent and pocket the margin. Hedge funds put on spread trades, long Brent and short WTI, to bet on geopolitical risk without taking a directional view on oil. Producers in the Permian Basin, North Dakota Bakken and the Canadian oil sands watch the spread to time exports by pipeline (Keystone, Trans Mountain) or rail. Airlines, shipping companies and chemical producers also pull from both benchmarks when modeling jet fuel and naphtha costs.

FAQ

Why is Brent usually more expensive than WTI? Brent reaches seaborne global markets more easily and carries the geopolitical premium attached to Europe, Africa and the Middle East. WTI is landlocked at Cushing and depends on pipeline capacity to get down to the Gulf Coast for export.

Which benchmark does OPEC follow? Most OPEC+ members set their official selling prices (OSPs) against Brent or against a Dubai/Oman basket. WTI stays mostly a North American reference.

What is a sour vs sweet crude? Sweet crude carries less than 0.5% sulfur (WTI, Brent); sour crude carries more (Dubai, Maya, Urals). Because sweet crude is cheaper to refine, it trades at a premium over the sour grades.
