US stock markets closed lower on Friday, with the Dow Jones Industrial Average falling 1.72%, the S&P 500 dropping 1.67%, and the tech-heavy NASDAQ shedding 2.15%. The declines were driven by ongoing tensions in the Middle East and fears that a prolonged conflict could disrupt global oil supplies, leading to a surge in energy prices and reigniting inflationary pressures. In contrast, the Toronto Stock Exchange closed higher, gaining 0.23%, boosted by strength in the base metals sector.

Why it matters

The volatility in the US stock markets reflects the significant impact that geopolitical events can have on the global economy. A disruption in oil supplies could lead to higher inflation, which could in turn prompt the Federal Reserve to maintain its aggressive interest rate hike policy, potentially slowing economic growth. The divergence between the US and Canadian markets highlights the importance of geographic diversification in investment portfolios.

The details

The primary driver of market anxiety remains the escalating tensions in the Middle East. Concerns are mounting that a prolonged conflict could disrupt global oil supplies, leading to a surge in energy prices. This, in turn, could reignite inflationary pressures that central banks have been working to contain. The price of West Texas Intermediate (WTI) crude oil finished up 5.46% at $99.64 a barrel, and Brent crude advanced 4.22% to $112.57, though remaining relatively stable for the week overall. Rising oil prices directly impact transportation costs, manufacturing expenses, and consumer spending, potentially slowing economic growth.
