The spot contract of West Texas Intermediate crude oil (WTI) in the United States is regarded as the benchmark price in the international energy market by many investors, and many media articles also take WTI as the representative price when describing the price trend of crude oil. However, from the recent trend, WTI crude oil price is more easily affected by the local supply and demand relationship, and has nothing to do with the fundamental changes in the global crude oil market. From this perspective, WTI is more like a regional oil price. Brent crude oil supply is generally stable and is less affected by local factors. From this point of view, compared with London Brent crude oil, the spot contract price of WTI crude oil futures looks more like a regional oil price, and has almost no international representation.
