The Globe and Mail reports in its Friday edition that Canada's aluminum industry is poised to benefit from elevated prices as global supply of the base metal continues to be disrupted by the war in the Middle East, where production sites have shut down or suffered critical damage. The Globe's Sophia Bertuzzi writes that while aluminum prices slid this week after the United States and Iran announced an interim peace deal, benchmark prices remain almost 10 per cent higher than when the conflict started in late February. Gulf countries produce around 9 per cent of the global aluminum supply. Their production normally flows through the Strait of Hormuz, which is reopening after months of an effective shutdown. "Aluminum was one of those secondary casualties of the conflict," said Marc Ercolao, an economist at TD Bank. While oil prices soared immediately after the conflict broke out, aluminum prices gradually rose and hit a four-year high in May as investors priced in war-risk premiums, increasing energy-related production costs and tightening supply. That offers something of a salve to the Canadian industry, which has been slammed by tariffs of 50 per cent on raw aluminum shipments to the U.S., in addition to other duties.
