US stock futures fell on Tuesday as rising oil prices and a global bond selloff revived concerns about inflation and pushed investors to increase bets that the Federal Reserve could raise interest rates. The weakness comes at the start of September, historically one of the more difficult months for US equities.
Futures tied to the Dow Jones Industrial Average and S&P 500 were down about 0.5% before the opening bell, while Nasdaq-100 futures fell roughly 1%, reflecting heavier pressure on technology stocks.
Oil Prices Fuel Inflation Concerns
The immediate trigger for the market’s latest move was another increase in crude prices.
Brent crude climbed above $92 a barrel after renewed fighting in the Middle East increased concerns about disruptions to energy supplies and shipping through the Strait of Hormuz. West Texas Intermediate crude also rose, adding to worries that higher energy costs could feed into consumer prices.
For investors, the problem is not simply that gasoline becomes more expensive.
Higher oil prices can increase transportation, manufacturing and logistics costs across the economy. If those costs remain elevated, businesses may pass them on to consumers, making it harder for inflation to decline.
Treasury Yields Surge
The oil-price increase has been accompanied by a sharp selloff in government bonds.
The US 10-year Treasury yield climbed above 4.75%, reaching its highest level since January 2025. The two-year yield also rose, reflecting growing expectations that the Federal Reserve may keep monetary policy restrictive or potentially raise rates.
Higher Treasury yields make stocks less attractive because investors can obtain better returns from relatively low-risk government securities.
They also increase borrowing costs for companies and households.
Fed Rate-Hike Bets Increase
Markets are increasingly focused on the possibility of a September Fed rate increase.
Recent hawkish comments from Federal Reserve officials have already shifted expectations, while rising energy prices are adding another reason for policymakers to remain cautious.
According to market pricing cited by the Wall Street Journal, traders were assigning a roughly 65% probability to a quarter-point rate increase at the September meeting.
That represents a significant change from earlier expectations that the next major policy move would be a rate cut.
Technology Stocks Take the Biggest Hit
Technology shares were among the weakest performers in premarket trading.
Nasdaq-100 futures declined more sharply than Dow and S&P 500 futures, while major semiconductor companies including Nvidia, Intel and AMD were under pressure.
Technology stocks can be particularly sensitive to higher interest rates because many of their valuations depend heavily on expectations for earnings and cash flows far into the future.
When bond yields rise, those future profits become less valuable in present-value terms.
September Adds Seasonal Pressure
The market is also entering a historically difficult period.
Since 1926, the S&P 500 has averaged a loss of about 0.7% in September, making it the weakest month of the year based on historical returns.
Seasonality alone is unlikely to determine market direction.
But when investors are already dealing with geopolitical uncertainty, higher oil prices and rising yields, the historically weak September backdrop can contribute to more cautious positioning.
Energy Stocks Move in the Opposite Direction
Not every sector is suffering from higher oil prices.
Energy companies stand to benefit when crude prices rise because stronger commodity prices can increase revenue and profit expectations.
Shares of Exxon Mobil and Devon Energy were higher in premarket trading as Brent crude gained.
That creates a sharp contrast within the equity market.
Energy producers can benefit from inflationary oil shocks, while airlines, transportation companies and other fuel-intensive businesses face higher operating costs.
Jobs Data Now in Focus
Investors are also looking beyond oil prices toward upcoming US economic data.
The Labor Department’s JOLTS report is due Tuesday, followed by the more important monthly employment report on Friday.
Those figures could influence the Fed’s decision by showing whether the labor market is weakening enough to justify keeping rates unchanged despite persistent inflation.
If employment remains resilient while inflation rises, the case for tighter monetary policy could strengthen.
If hiring deteriorates significantly, policymakers would face a more difficult trade-off.
The Market’s Main Risk
The biggest concern for investors is a combination of slower growth and higher inflation.
A sustained oil shock could push inflation upward while simultaneously reducing household purchasing power.
That would create conditions similar to a mild stagflationary environment.
The Federal Reserve would then face an uncomfortable choice between fighting inflation with higher rates and supporting an economy weakened by rising energy costs.
Investors Turn Defensive
The latest decline suggests that investors are becoming more sensitive to macroeconomic risks after a strong August.
The Dow, S&P 500 and Nasdaq had entered September after posting gains over the previous month, but the new rise in oil and Treasury yields has quickly shifted sentiment.
For now, the market is not signaling an economic collapse.
Instead, investors are repricing the cost of persistent inflation and the possibility that interest rates may remain higher for longer.
Conclusion
US stock futures are starting September under pressure as rising oil prices, higher Treasury yields and growing expectations for Federal Reserve tightening weigh on investor sentiment.
The renewed Middle East conflict has pushed Brent crude above $92 a barrel, increasing fears that energy costs could keep inflation elevated. At the same time, the US 10-year Treasury yield has climbed above 4.75%, its highest level since early 2025.
Technology stocks are bearing much of the immediate pressure, with Nasdaq futures falling more sharply than the broader market.
The next major test will come from US economic data, particularly the jobs report due Friday. A strong labor market combined with persistent inflation could reinforce expectations for higher interest rates.
For investors, the central question is no longer simply whether the economy is growing.
It is whether growth can continue while oil prices rise, inflation remains stubborn and borrowing costs move higher.
That combination could make September considerably more volatile than August.
