Oil prices fell as expectations of more supply grew after the Strait of Hormuz reopened and Iran was set to lift sales under a 60-day interim deal with the U.S. August Brent futures traded around US$72 a barrel on Friday, the lowest since late February, while Western Canada Select slipped below US$60. Canadian retail gasoline prices, however, stayed elevated at about $1.57 to $1.58 per litre, with inventories depleted during the war and taxes limiting how quickly pump prices can fall, according to Dan McTeague of Canadians for Affordable Energy.
