Although there are many types of crude oil, two names dominate the global market: Brent and WTI. These two crudes are used as global benchmarks to set the price of a barrel, regardless of whether buyers are purchasing that exact oil. In other words, they act as reference indexes for the energy market.
Brent: The International Benchmark
Brent Crude comes from oil fields located in the North Sea, between the UK and Norway. It is considered a light and sweet crude (low density and low sulfur content), making it ideal for producing gasoline, diesel, and other high-demand products. Because of this, Brent is the main benchmark in Europe, Asia, and Africa, representing nearly two-thirds of the world’s oil trade.
WTI: The U.S. Reference
West Texas Intermediate (WTI) is another light and sweet crude, primarily extracted and traded in the United States. Although in recent years it has lost some ground to Brent, WTI remains crucial for setting prices in the Americas and as a global economic indicator.
Why Two Benchmarks?
Oil is not a uniform product—its quality varies depending on where it is extracted, as do the transportation costs, refining capacity, and regulation. Having two major benchmarks allows regional markets to adjust to local realities while still remaining connected through international trade.
How Brent and WTI Influence Gasoline Prices
Although crude oil undergoes many processes before becoming gasoline or diesel (as we explained in the previous article on refining), the barrel price is the starting point. An increase in Brent or WTI automatically raises the cost of crude purchased by refineries, which directly impacts:
- Fuel prices at gas stations.
- Transportation costs for goods.
- Prices of petroleum-derived products such as plastics and fertilizers.
These benchmarks create a domino effect that can be felt throughout the economy.
Brent and WTI are not just technical names—they are the thermometers of the global energy market. When their prices change, they affect not only the cost of fuel at gas stations but also the prices of countless goods and services that depend on oil—from the plastics we use every day to the food we eat (through transportation and production costs). Understanding what they are and how they work helps us grasp why oil prices rise or fall and how that influences our economy and the daily lives of millions of people worldwide.
