Geopolitical tensions between the United States and Iran have contributed to significant market volatility and energy price fluctuations.

In late July, the Ned Davis Research Trump Trade Index fell approximately 16% since May. Analysts linked this decline to the US-Iran conflict, which pushed energy prices higher, increased inflation expectations, raised interest rates, and strengthened the US dollar.

By mid-August, these tensions continued to impact global markets. Concerns regarding shipping stability in the Persian Gulf drove crude oil prices higher, with the October contract reaching US$86.83 per barrel. This instability contributed to volatility in the S&P/TSX Composite Index, as investors monitored energy pressures and inflation concerns.
