Canada's main stock index slipped 0.6% on Thursday, as a fresh bond selloff pushed long-term interest rates toward multi-decade highs and weighed heavily on the financial sector. But the decline was cushioned by gains in technology and energy stocks, which stayed in positive territory thanks to AI optimism and firmer oil prices.
What happened
The Toronto Stock Exchange's composite index fell, with financial stocks leading the decline. Banks and other financial firms are particularly sensitive to rising bond yields, because higher yields can squeeze borrowing margins and slow down lending activity. In this session, financials sank 1.7%, with notable drops in EQB, Bank of Montreal, and Royal Bank of Canada, each down more than 2%.
The trigger was a move in government bond markets. The 10-year US Treasury yield touched 5.34%, its highest level since 2002, while Canada's 10-year yield reached 4.01%. When government bond yields rise, investors can earn more from holding safer assets, which makes stocks look relatively less attractive. That dynamic tends to hit rate-sensitive sectors first, and banks are often the most exposed.
At the same time, technology stocks held up, driven by continued enthusiasm around artificial intelligence. AI-related companies have been a bright spot in markets this year, as investors bet on strong demand for computing power and data infrastructure. Energy stocks also gained, supported by rising oil prices, which typically benefit Canadian producers.
Why bond yields matter
Government bond yields are essentially the interest rate that investors earn for lending to the government. When yields rise, it often signals that investors expect higher inflation or stronger economic growth, or that central banks will keep interest rates higher for longer. For stock investors, higher yields mean that the future profits of companies are discounted more heavily, reducing the present value of those earnings.
This is why the recent climb in yields has rattled markets globally. The 10-year US Treasury yield hitting its highest level in over two decades is a significant milestone, and it has been a key driver of volatility across stock markets. In Canada, the 10-year yield crossing the 4% mark is also notable, as it reflects similar pressures in the domestic bond market.
For everyday investors, the takeaway is that rising bond yields can create headwinds for stocks, especially those in interest-rate-sensitive sectors like financials. However, not all stocks react the same way. Companies with strong growth prospects, such as those in the tech sector, may still perform well if investors believe their earnings can outpace the drag from higher discount rates.
What it means for investors
The divergence between financials and tech/energy highlights how different sectors can respond to the same macro backdrop. For Canadian investors, the TSX is heavily weighted toward financials, so a move like Thursday's can feel broad even when other parts of the market are doing fine.
Investors should also keep an eye on oil prices, which have been climbing and are a key driver for Canada's energy-heavy index. Higher oil prices can boost the earnings of energy companies and support the Canadian dollar, but they can also add to inflationary pressures, which may keep central banks cautious.
Looking ahead, market watchers will be focused on whether bond yields continue to climb and how that affects the broader economy. The recent moves in yields have been driven by a combination of strong economic data and concerns about government debt levels. If yields keep rising, it could put more pressure on stocks, particularly those with high valuations and long-duration earnings.
For now, the TSX's resilience outside of financials suggests that investors are still willing to pay up for growth stories like AI, while energy provides a hedge against inflation. But the bond market remains the key variable to watch, as it has the power to shift sentiment quickly.
As always, it's important to remember that markets are volatile and past performance is not a guarantee of future results. Diversification across sectors and asset classes can help manage risk, especially in times of rising rates.
