There are two primary sources of oil traded in the markets, and those are the Brent crude that originates from the North Atlantic, and West Texas Intermediate (WTI) crude that originates in the Permian Basin in the U.S. Both are considered high grades of oil, and both enjoy large global trading volumes. Until 2010 the price of both remained basically the same, but since then WTI crude has traded at a discount due to the growing U.S. production of oil. Another difference is in the demand for each, with Brent demand coming primarily from Europe, and to a lesser extent Asia, and WTI crude demand coming from the U.S. Traders can profit from either.
