CANADA-CRUDE-Discount on Western Canada Select heavy crude narrows

March 5 (Reuters) - The discount of Western Canada Select (WCS) heavy crude to the North American benchmark West Texas Intermediate futures (WTI) CLc1 narrowed on Wednesday, a day after U.S. President Donald Trump's tariffs on goods from Mexico and Canada took effect.

WCS for April delivery in Hardisty, Alberta, settled at $13.60 a barrel under WTI, according to brokerage CalRock, after having settled at $13.70 under the U.S. benchmark on Tuesday.

Trump on Tuesday applied 25% tariffs to most Canadian goods and 10% to energy products.

Canada exports approximately 4 million barrels of oil per day, about 90% of its total crude exports, to the United States.

The Canadian heavy crude market had a "knee-jerk reaction" to the tariffs immediately following their implementation, said RBN Energy analyst Martin King.

The discount on WCS could widen further if tariffs stay in effect, King said, but it will take a month or more for the market to assess the impact of tariffs on Canadian crude demand south of the border.

Canada's large oil producers will still be profitable even if the WCS discount widens by up to $4 to $5, King said. "That would be perfectly manageable for the Canadian oil and gas producer."

Globally, oil prices settled down for the fourth consecutive session on Wednesday after U.S. crude oil stockpiles posted a larger-than-expected build, adding a further headwind as investors worried about OPEC+ plans to increase output in April and U.S. tariffs on Canada, China and Mexico.
