Through Petroleum, Russia and Sulfur

Benchmarks are used because there are many different varieties and grades of crude oil. Using benchmarks makes referencing types of oil easier for sellers and buyers.

There is always a spread between WTI, Brent and other blends due to the relative volatility (high API gravity is more valuable), sweetness/sourness (low sulfur is more valuable) and transportation cost. This is the price that controls world oil market price.

West Texas Intermediate (WTI)

West Texas Intermediate is used primarily in the U.S. It is light (API gravity) and sweet (low-sulfur) thus making it ideal for producing products like low-sulfur gasoline and low-sulfur diesel. Brent is not as light or as sweet as WTI but it is still a high-grade crude. The OPEC basket is slightly heavier and more sour than Brent. As a result of these gravity and sulfur differences, (at least before 2011) WTI is typically traded at a dollar or two premium to Brent and another dollar or two premium to the OPEC basket. Since 2011, WTI has traded at lower prices than Brent.
