West Texas Intermediate (WTI) is a benchmark for oil prices in the United States based on light, low sulfur WTI crude.

WTI remains the benchmark for oil prices in the U.S. despite the fact that its production has been falling for years.

Historically, it has traded closely to Brent and the OPEC Basket but currently it has been discounted against Brent crude oil. Historical price data for WTI can be found at a website by the Energy Information Administration of the Department of Energy. It is listed as WTI, Cushing, Oklahoma.
