Canadian stock futures edged higher Tuesday as oil prices extended their losses on hopes for possible U.S.-Iran diplomatic progress at this week’s United Nations meeting and the reported resumption of Saudi pipeline operations. Iran reportedly offered to reopen the Strait of Hormuz within seven days if Washington eases military pressure, while Bank of Canada Governor Tiff Macklem warned that U.S. tariffs could push fourth-quarter growth below 1%. Falling oil prices supported credit-sensitive stocks after an earlier energy rally intensified inflationary pressure and contributed to major central banks raising interest rates. Macklem said future rate decisions would need to balance weaker growth against higher energy costs linked to the Iran conflict. Gold also edged lower, weighing on mining stocks.
