There is no uniform crude oil price in the world. 1983, NYMEX (the New York Mercantile Exchange) launched a light and low-sulfur crude oil futures contract, commonly known as WTI crude oil. Because the United States is the largest energy consumer in the world, and NYMEX's WTI crude oil futures are the most active crude oil trading varieties, it is gradually used to call it "international oil price" or "crude oil price", which generally refers to WTI crude oil price. Historically, on July 1 1 day, 2008, WTI crude oil once reached an all-time high of 147.27 USD/barrel due to the continuous tension in the Middle East and the market's concern about the global crude oil supply shortage.
