Brent is a blended crude stream produced in the North Sea region which serves as a reference or “marker” for pricing a number of other crude streams.
West Texas Intermediate (WTI), also known as Texas light sweet, is a grade of crude oil produced in Texas and southern Oklahoma which serves as a reference or “marker” for pricing a number of other crude streams and which is traded in the domestic spot market at Cushing, Oklahoma. This grade is described as light because of its relatively low density, and sweet because of its low sulfur content. It is the underlying commodity of New York Mercantile Exchange’s oil futures contracts.
The price of WTI is often referenced in news reports on oil prices, alongside the price of Brent crude from the North Sea. Other important oil markers include the Dubai Crude, Oman Crude, Urals oil and the OPEC Reference Basket. WTI is lighter and sweeter than Brent, and considerably lighter and sweeter than Dubai or Oman.
