Canada’s main stock index, the S&P/TSX composite, rises by more than 300 points in late-morning trading. The gain is reported alongside a decline in oil prices. Both developments are attributed to news that the United States and Iran reached an initial agreement. According to the reports, the agreement is intended to extend their ceasefire and set conditions that would lead to the reopening of the Strait of Hormuz. The Strait of Hormuz is a key shipping route for global oil supplies, and the prospect of improved access is linked in the reporting to downward pressure on oil prices. The sources describe a market reaction in which equities in Canada move higher while oil declines as investors adjust expectations for supply and geopolitical risk. The reports do not provide additional details on sector performance, trade volume, or specific company movers, focusing instead on the broad index change and oil’s direction following the U.S.-Iran announcement.
