Discounts on heavy crude oil from Western Canada are narrowed

Western Canada Select (WCS), a heavy crude from Canada, was trading at a discount to West Texas Intermediate (WTI), the benchmark North American futures contract. The discount narrowed Friday, despite the fact that the Keystone pipeline between Canada and the U.S.A. was still shut for the fourth day in a row.

WCS for delivery in May at Hardisty, Alberta settled at $9.60 per barrel below WTI according to brokerage CalRock. It had settled at $9.85 below the U.S. benchmark Thursday.

Keystone, the oil pipeline that connects Canada and the U.S., was closed on Tuesday following an oil spillage in North Dakota. South Bow, the owner and operator for the 4,327 km (2,689 miles) pipeline, said on Friday that they were still investigating the cause and did not have a timetable for restart. * Although the WCS discount increased in the immediate wake of the Keystone shut down, it remains historically low due to U.S. sanctioned countries producing heavy crude, such as Venezuela and lower heavy crude exports by Mexico.

Canadian heavy crude differentials tend to shrink when oil prices in the world are low, partly because lower prices lead to less competition among Canadian producers for pipeline space. This week, global oil prices fluctuated dramatically as traders reassessed the geopolitical risk of the crude market due to President Donald Trump's new tax regime.
