Key Takeaways
  • • Canada's S&P/TSX Composite Index rallied to a record high, gaining 294.06 points to close at 34,346.29, driven primarily by a surge in energy stocks as oil prices jumped amid Middle East geopolitical tensions.
  • • U.S. benchmark indices reached all-time highs, with the S&P 500 climbing 1.2% to a record close and the Nasdaq advancing 365.78 points, completing a third consecutive week of substantial gains—the longest winning streak since early November.
  • • Oil prices initially spiked more than 10% following escalating U.S.-Iran tensions and a U.S. naval blockade of Iranian ports announced by President Trump, though prices later pared gains to settle under $100 per barrel as ceasefire announcements provided relief.
  • • Iran's Foreign Minister Abbas Araghchi declared the Strait of Hormuz "completely open" for commercial vessel passage as a ceasefire in Lebanon holds, immediately triggering a sharp decline in oil prices and easing earlier inflation and growth concerns among investors.
  • • The volatile trading reflected competing geopolitical narratives: Trump's blockade announcement initially drove crude higher, but subsequent ceasefire signals and the Strait of Hormuz reopening announcement shifted market sentiment toward risk-on positioning across North American equities.
Summary
Canada's main stock index posted gains to approach record territory on Monday as energy stocks rallied following volatile geopolitical developments in the Middle East. The S&P/TSX Composite Index advanced 294.06 points to 34,346.29, with energy sector strength offsetting earlier weakness in other segments. U.S. markets similarly climbed to all-time highs, with the S&P 500 leaping 1.2% and the Nasdaq composite gaining 365.78 points, extending the benchmark's winning streak to three consecutive weeks—its longest advance since late October.

The primary driver was oil's volatile trajectory following competing announcements regarding U.S.-Iran tensions and Middle East ceasefire developments. President Trump announced a U.S. Navy blockade of Iranian ports designed to pressure Tehran into opening the Strait of Hormuz, initially sending crude prices sharply higher amid concerns about further supply constraints. However, Iran's Foreign Minister Abbas Araghchi subsequently announced via social media that passage through the Strait of Hormuz "is declared completely open" for all commercial vessels, contingent on the Lebanon ceasefire holding. This declaration immediately triggered a substantial reversal, with crude prices plunging more than 10% in the minutes following the announcement. The June crude contract fell by approximately $8, while prices ultimately settled just under $100 per barrel.

Market participants viewed the Strait of Hormuz reopening as significantly de-risking near-term economic concerns. Anish Chopra, managing director at Portfolio Management Corp., noted that the opening dispelled "concerns about inflation, there were concerns about growth, there were concerns about the price of oil," creating at least temporary market relief. Brent Joyce, chief investment strategist at BMO Private Wealth, characterized the rally as "a relief rally that we have enough of a ceasefire holding in the Middle East to be viewed as constructive." International benchmark Brent crude had climbed 4.4% earlier in the session to $99.36 per barrel, substantially above the roughly $70 level before the conflict escalated.

The trading session illustrated the tension between competing risk narratives: Trump's blockade announcement and prior weekend ceasefire talks breakdown had initially driven safe-haven flows into oil, yet the subsequent Strait of Hormuz reopening shifted sentiment toward risk-on equities. The Dow Jones industrial average advanced 868.71 points to 49,447.43, while the broader market's continued ascent reflected investor appetite for equity exposure on the assumption that energy supply chain risks were moderating. However, Trump's subsequent statement that the U.S. blockade would remain "in full force" pending a comprehensive deal suggested ongoing geopolitical uncertainty, even as immediate market response favored the relief narrative.
