Canada's main stock index, the TSX, fell 0.95% on Tuesday as a jump in oil prices and losses in bank and mining stocks offset gains in the energy sector. The decline came as geopolitical tensions between the US and Iran pushed crude oil to its highest level in over a month, while gold prices slid to their lowest since June 30.
Oil Surge on US-Iran Tensions
US crude oil futures rose 4.4% to $73.52 per barrel, their highest since June 18, while Brent crude climbed 5.1% to $77.96. The rally was triggered by a flare-up in hostilities between the United States and Iran, raising concerns about potential supply disruptions in the Middle East, a key oil-producing region.
Higher oil prices typically benefit energy companies, and that was evident on the TSX, where energy stocks led the gainers. However, the broader market felt the weight of other sectors. Rising crude can also reignite inflation worries, which often strengthens the US dollar and makes interest-bearing assets like bonds more attractive. That dynamic tends to pressure gold, which doesn't pay interest, and it fell 2% to $4,076.50 an ounce, its lowest since June 30. The decline in gold weighed on mining stocks, including those in battery metals and base metals, which are sensitive to economic growth expectations.
Bank Stocks Under Pressure
The bigger drag on the TSX came from the financial sector, particularly the banks. The International Monetary Fund (IMF) recently cut its growth forecast for Canada to 1.1% this year and 1.7% in 2027, citing slower population growth, weak investment, and trade uncertainty. A weaker economy can reduce demand for loans and lower fee income from areas like payments and wealth management, which directly impacts bank profits.
Adding to the concern, investment bank Jefferies noted that, except for Scotiabank and EQB, Canadian banks are trading on next-twelve-month price-to-earnings multiples above their post-2005 highs. This is happening even though their average return on equity (ROE) is 14.6%, slightly below the historical average of 15.4%. ROE measures how effectively a company generates profit from shareholders' equity, and a lower ROE can make high valuations harder to justify.
Banks are heavyweights on the TSX, so when they stumble, the entire index feels it. If investors are already paying peak-like valuations for most lenders, any slip in earnings expectations could lead to a sharper drop in stock prices. The IMF's downgrade adds to that risk, as slower growth often translates into weaker bank performance.
What It Means for Investors
For everyday investors, the TSX's decline highlights how different sectors can move in opposite directions on the same day. Energy stocks rose on the oil rally, but that wasn't enough to offset losses in financials and mining. The key takeaway is that geopolitical events, like the US-Iran tensions, can create short-term volatility, but broader economic trends—such as Canada's growth outlook—have a more lasting impact on the market.
The IMF's growth forecast cut is a reminder that Canada's economy faces headwinds from slower population growth, weak investment, and trade uncertainty. For bank investors, this means keeping an eye on loan growth and fee income, which are sensitive to economic activity. Jefferies' analysis suggests that current valuations leave little room for error, so any negative surprises in earnings could hit bank stocks hard.
On the positive side, the oil rally could support energy stocks in the near term, especially if tensions in the Middle East persist. However, investors should be aware that higher oil prices can also fuel inflation, which might prompt central banks to keep interest rates higher for longer. That could further pressure rate-sensitive sectors like real estate and utilities.
For those looking at the broader market, the TSX's performance reflects a tug-of-war between energy gains and financial losses. Diversification remains important, as no single sector can guarantee stability in a volatile environment. As always, staying informed about both geopolitical events and economic data can help investors make more thoughtful decisions.
