The Globe and Mail reports in its Tuesday, March 17, edition that oil prices fell on Monday as hopes arose that President Donald Trump could convince allies to provide naval support for reopening the Strait of Hormuz, a crucial oil shipping route. The Globe's Jeffrey Jones writes that global leaders have been hesitant to patrol the area, while Iran has vowed to block the strait with missiles, drones and mines in response to ongoing United States and Israeli attacks. Oil prices have hit four-year highs due to the attacks and Iran's retaliations, raising concerns about energy shortages and a potential global recession, with jet and diesel fuel costs skyrocketing. On Monday, British Prime Minister Keir Starmer said Britain is collaborating with allies to open the strait, though he provided few specifics or a timetable. He noted that, despite Mr. Trump's call for NATO support in opening the strait, any actions would not be a NATO mission. International benchmark Brent crude fell about 3 per cent to close the session at $100.21 (U.S.) a barrel on Monday. West Texas Intermediate crude sank 5 per cent to $93.50 (U.S.) a barrel. Despite the easing, prices remain nearly 40 per cent higher than before the war began.
