Oct 15 (Reuters) - The discount on Western Canada Select to North American benchmark West Texas Intermediate futures CLc1 settled at $10.25 a barrel under the U.S. benchmark WTI on Wednesday, its narrowest differential since July.
WCS for November delivery in Hardisty, Alberta, narrowed from $10.30 a barrel on Tuesday, according to brokerage CalRock.
The WCS discount typically widens after the summer driving season ends, but has seen a contrary pattern this year.
October's tight discount is being driven by supply impacts from seasonal maintenance in the Canadian oil sands, strong Asian buying, and strong demand from U.S. refineries, analysts say.
Oil prices eased on Wednesday to a five-month low on escalating U.S.-China trade tensions and the International Energy Agency's prediction of a supply surplus in 2026.
