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

March 17 (Reuters) - The discount of Western Canada Select (WCS) heavy crude to the North American benchmark West Texas Intermediate futures (WTI) CLc1 widened on Monday.

WCS for April delivery in Hardisty, Alberta, settled at $10.65 a barrel under WTI, according to brokerage CalRock, after having settled at $10.40 under the U.S. benchmark on Friday.

The differential between Canadian heavy crude and WTI remains approximately $3 tighter than it was at the start of the month.

The differential tends to widen when oil prices are higher overall and narrow in lower price environments.

U.S. President Trump's trade war with other countries, including Canada, has roiled financial markets, raised recession fears and caused global oil prices to plummet on fears that demand could exceed supply.

Oil prices rose slightly on Monday after the U.S. vowed to keep attacking Yemen's Houthis until the Iran-aligned group ends its assaults on shipping, while Chinese economic data buoyed hopes for higher demand.
