The stock market is entering a critical period as investors increasingly question whether the powerful rally of 2026 is beginning to lose momentum. U.S. and Canadian markets are both facing a combination of rising oil prices, higher bond yields, renewed inflation concerns and geopolitical uncertainty. The S&P 500 has now suffered four consecutive daily declines, while the S&P/TSX Composite has also fallen for four straight sessions and recently reached a five-week low.
The central question for investors is whether this is simply a normal pullback within a longer-term bull market or the beginning of a broader market-topping process. The evidence does not yet confirm a major market top, but several warning signs are becoming increasingly difficult to ignore.
One of the biggest concerns is the sharp increase in oil prices. Brent crude has moved above $100 per barrel and briefly traded above $108, while U.S. crude has also moved above $100. The surge has been driven largely by escalating geopolitical tensions and concerns about disruptions to global oil supplies. Higher energy prices are particularly important because they can quickly feed into transportation, manufacturing and consumer prices, creating renewed inflationary pressure.
At the same time, bond yields have moved sharply higher. The U.S. 10-year Treasury yield has approached 5%, while the 30-year Treasury yield has climbed above 5.3%. Higher yields increase borrowing costs and raise the discount rate applied to future corporate earnings, which can put significant pressure on highly valued growth and technology stocks.
This creates what could be described as a negative market combination of higher oil, higher yields and higher inflation expectations. If oil remains elevated, inflation could become more persistent and reduce the Federal Reserve’s ability to ease monetary policy. Investors are already becoming more cautious about the path of interest rates, with upcoming inflation data taking on greater importance for the September market outlook.
U.S. Market Outlook
The U.S. market remains fundamentally supported by strong corporate earnings, artificial intelligence investment and economic growth, but valuations leave less room for disappointment. The S&P 500 remains positive for the year despite its recent decline, but the index is now showing signs of weakening momentum. The Nasdaq is also particularly vulnerable because technology and AI stocks have benefited significantly from the long-running decline in interest-rate expectations.
The most important technical question is whether the S&P 500 can stabilize and regain its recent highs or whether the current weakness develops into a more pronounced topping pattern. A failure to recover, followed by a sustained break below key technical support, would increase the probability that the market has entered a larger correction.
Canadian Market Outlook
The Canadian market faces many of the same risks, but its sector composition creates a different dynamic. The TSX has traditionally benefited from exposure to energy, financials and materials, meaning higher commodity prices can provide an important cushion. However, the recent market action demonstrates that higher oil prices are no longer automatically bullish for Canadian stocks because investors are increasingly concerned about the inflation and interest-rate consequences.
The TSX recently fell to its lowest level since early August, with higher oil prices and rising bond yields weighing on sentiment. Precious metals and copper also weakened, adding additional pressure to the materials sector.
Canadian financials remain fundamentally important to the market, but higher bond yields can create a more complicated environment. Banks can benefit from stronger economic activity and higher lending rates, but rising borrowing costs can eventually pressure consumers, housing activity and credit quality. Elevated valuations after a strong run also leave financial stocks more vulnerable to a broader market correction.
Energy remains one of the strongest areas of the Canadian market because producers and infrastructure companies can benefit directly from higher crude prices. However, if oil prices remain elevated because of geopolitical instability rather than improving global demand, investors could begin to view the energy rally as a temporary risk premium rather than the beginning of a sustainable commodity cycle.
Materials and gold could also remain attractive if geopolitical uncertainty persists. Precious metals can provide defensive characteristics during periods of inflation and market volatility, while Canadian investors continue to benefit from the country’s significant exposure to mining and natural resources.
September Market Forecast
The current September outlook is cautiously bearish, but this does not mean that a bear market has begun. The more likely near-term scenario is increased volatility and a potential 5% to 10% move lower as investors reassess valuations, interest rates, inflation and economic growth.
The bullish scenario would develop if oil prices stabilize or retreat, Treasury yields move lower and inflation remains contained. In that environment, the current pullback could prove to be a healthy consolidation, allowing both the S&P 500 and TSX to eventually resume their upward trends.
The bearish scenario becomes more concerning if oil remains above $100, the U.S. 10-year Treasury yield moves decisively above 5% and inflation expectations continue rising. Such a combination could place significant pressure on equity valuations and potentially turn the current weakness into a deeper market decline.
For Canada, the relative strength of energy, financials and materials could provide some protection compared with the technology-heavy U.S. market. However, the TSX would not be immune to a broader global risk-off move, particularly if higher interest rates begin weighing on economic activity.
Outlook
The September market outlook is becoming increasingly defensive. The market has not confirmed a major top, but the ingredients for a meaningful correction are now in place. Rising oil prices are threatening to reignite inflation, bond yields are approaching levels that could pressure stock valuations, and both U.S. and Canadian indexes are showing weakening short-term momentum.
Investors should closely monitor four indicators through the remainder of September: oil prices, the U.S. 10-year Treasury yield, inflation data and the technical support levels on the S&P 500 and TSX.
If oil and yields continue higher while the major indexes fail to recover, the probability of a larger correction will increase. If oil prices stabilize, yields retreat and corporate earnings remain strong, the recent weakness could instead represent a temporary pause in the broader bull market.
