Canadian Heavy Crude Discount Tops $31 a Barrel, Widening to Levels Last Seen in 2018

Key Facts

4Cenovus was scheduled to report third-quarter results before the market opened on November 4.

The discount on Western Canadian Select (WCS) crude widened to more than $31 a barrel in late October, from less than $22 at the end of September, Investing.com reported, citing Reuters. The spread reached levels not seen since the 2018 pipeline crisis, according to the report. The widening puts realized prices and Canadian producers’ margins to the test as Cenovus prepares to report third-quarter results. Investors were watching in particular for the discount’s effect on the company’s profitability despite record production volumes. The widening gap between Canadian heavy crude and the U.S. benchmark makes realized-price developments a key focus in assessing producers’ performance.

Pressure on Canadian heavy crude in the United States was linked to increased imports from Venezuela and higher shipping costs, according to a Bloomberg report published by EnergyNow. The report said Venezuelan crude is similar in quality to Canadian crude, making it a competitor for buyers’ demand. Higher shipping costs also reduced demand, according to the report. Tanker movements disrupted by the war on Iran impeded exports from the U.S. Gulf Coast. Together, these factors brought competitive pressure, transportation costs and disruption to export routes into the heavy-crude market.

Stephen Ledbetter, chief operating officer at HF Sinclair’s refinery, said tanker disruptions left large volumes of crude aboard ships. He added, "All of that ends up pressuring WCS." The description directly links the disruption to shipping movements with pressure on Canadian crude prices, as Bloomberg’s report also cited higher transportation costs and affected exports from the U.S. Gulf Coast. Reuters’ price comparison showed the discount widened by more than $9 a barrel between the end of September and late October, while remaining measured as a price spread against the benchmark crude rather than by the direction of oil prices alone. Similar levels were recorded during the 2018 pipeline crisis, according to the report.

Expectations for the discount’s effect on Cenovus were reflected in its share price ahead of the results. The stock fell 6.3% on November 2, while remaining up 84% year to date through November 3, according to Investing.com. The decline coincided with investors’ focus on how the Canadian heavy crude discount could affect the company’s profitability despite record production volumes. The report does not attribute the share move to a single factor, but places it in the context of expectations for the results and the widening discount. Cenovus is scheduled to report third-quarter results before the market opens on November 4, providing indicators of the pricing impact on the company’s performance.
