Un explication sur l’écart du prix du pétrole entre Brent et WTI, et pourquoi l’un et l’autre reflètent de moins en moins la réalité :
theglobeandmail : Brent v. WTI: A crude oil smackdown
– there are many grades of oil and more than one oil price barometer.
– The two biggies are the prices of West Texas Intermediate (WTI) crude oil and Brent crud
– Soaring production from the Alberta oil sands and oil-rush U.S. states, notably North Dakota, have flooded the Cushing oil supply hub, which lacks pipeline capacity to move it efficiently to oil refineries on the Gulf coast
– the price spread between WTI and Brent has expanded to ridiculous levels
– In 2009, the Saudis dropped the WTI contract as their benchmark, [Brent is now] 65% of the world’s crude trade
– refineries are buying WTI crudes at depressed Cushing prices and selling at prices apparently linked to Brent
