North American stock markets began Thursday on a downward trajectory, influenced by rising oil prices and climbing treasury yields amidst the persistent deadlock between Iran and the United States. Higher yields tend to dampen economic growth and exert pressure on various investment classes, including equities and cryptocurrencies. In particular, these elevated rates could hinder corporate borrowing, which has been instrumental in funding the AI data centres propelling recent economic expansion in the U.S.
Treasury Yields Climb as Concerns Mount
The yield on the 30-year Treasury bond, often viewed as a key indicator of geopolitical and fiscal risk, rose by 1.7 basis points to reach 5.139 per cent. Earlier in the week, it briefly peaked at 5.197 per cent—the highest level since July 2007, prior to the global financial crisis. This upward trend in yields is a reflection of investor apprehension regarding the ongoing geopolitical situation and its potential implications for the economy.
The major U.S. indices, including the S&P 500, Dow Jones Industrial Average, and Nasdaq, each experienced a decline of approximately half a per cent shortly after the market opened. Toronto’s Stock Exchange mirrored this trend, dipping by about 0.25 per cent.
Retail Sector Reacts to Economic Pressures
In the retail sector, Walmart’s shares fell over six per cent following the announcement of another strong quarter in sales, yet the company’s outlook fell short of analysts’ expectations. The retail giant has resonated with increasingly cautious American consumers, as inflation continues to erode purchasing power—particularly in light of the economic uncertainties stemming from the Iran conflict.

Meanwhile, Nvidia exhibited volatility in its stock performance, fluctuating between minor gains and losses overnight. The AI chipmaker reported quarterly results that exceeded Wall Street’s expectations, driven by an astonishing 85 per cent surge in revenue, largely due to soaring demand for its premium AI chips.
Oil Prices on the Rise
Early Thursday saw a notable increase in oil prices, rebounding from a five per cent drop the previous day. Brent crude, the international benchmark, climbed nearly $4 to approach $109 per barrel, while the U.S. benchmark, WTI crude, added $4 to reach $102 per barrel. These prices remain significantly elevated compared to the approximately $70 per barrel seen prior to the outbreak of conflict with Iran. The fluctuations are largely attributed to the ongoing uncertainty surrounding potential agreements between the U.S. and Iran, which would allow for the resumption of oil deliveries from the Persian Gulf to global markets.
Treasury Yields Reflect Market Sentiment
The resurgence in treasury yields followed a brief easing that had provided a lift to the markets. The yield on the 10-year Treasury bond increased to 4.60 per cent after dipping to 4.57 per cent the day prior, having reached as high as 4.67 per cent earlier in the week. Prior to the outbreak of hostilities with Iran, the 10-year yield had been below four per cent, reflecting rising global concerns that prolonged conflict would sustain high oil prices, among other economic ramifications.

The previous day’s drop in yields had been prompted by comments from U.S. President Donald Trump, who indicated that peace negotiations with Iran were nearing completion, resulting in a selloff in both U.S. and global bond markets.
Why it Matters
The current market dynamics underscore a critical intersection of geopolitical tensions and economic indicators, revealing how deeply interconnected these spheres are. As oil prices surge and treasury yields climb, the implications for consumer spending, corporate investment, and overall economic health are significant. With inflation already impacting household budgets, the ongoing volatility in energy markets may further constrain economic recovery efforts, highlighting the need for close monitoring of geopolitical developments and their financial repercussions.
