Equities on Wall Street retreated Tuesday as oil prices continued their upward trajectory, fueling concerns over persistently elevated inflation.

The S&P 500 index declined by 0.4%, while the Dow Jones Industrial Average shed 190 points, or 0.4%, as of 12:05 p.m. Eastern time.

Concurrently, the Nasdaq composite slipped 0.5%.

The sluggish start to September follows a turbulent yet largely favorable month for Wall Street.

All major indices posted gains in August.

However, the same persistent concerns continue to loom over the market, including apprehension about escalating inflation, sovereign debt, and the repercussions of global conflicts on both the U.S. and the worldwide economy.

Technology stocks were among the biggest drags on the market, with Microsoft down 1.3% and Advanced Micro Devices down 2.4%.

Their large market values tend to give them more sway over the broader market's direction, and their growth during the AI boom has relied heavily on borrowing, which becomes more expensive as interest rates rise.

Wall Street is off to a sluggish start in September, following a turbulent yet predominantly favorable month.

A significant portion of the ongoing strain on Wall Street stems from a persistent sell-off in U.S. government bonds.

The yield on the 10-year Treasury, which typically influences mortgage rates, climbed to 4.77% from 4.75% late Monday, having dipped as low as 4.20% at the start of 2026.

The yield on the two-year Treasury note, a benchmark that closely mirrors market expectations for Federal Reserve interest-rate moves, rose to 4.37% from 4.34% late Monday.

This is a significant increase from roughly 3.50% at the start of 2026.

The inverse relationship between bond yields and prices means that yields rise as prices fall, and rising yields indicate that investors are demanding higher returns on Treasurys because they perceive them as riskier.

The growing government debt is underscoring this risk.

The U.S. national debt crossed the $40 trillion mark two weeks ago—a sobering milestone, as defense costs and interest on the expanding deficit now account for a significant share of federal spending.

The bond sell-off is a global trend, with other countries facing similar economic pressures.

Elevated yields on bonds signal increased borrowing costs for mortgages and an array of other credit products.

These higher borrowing costs tend to dampen investment activity, including equities, while simultaneously impeding business expansion efforts.

Oil prices have exerted considerable pressure on inflation, bond yields, and the broader equities market.

Brent crude, the international benchmark, climbed 2.3% to $92.61.

Energy costs remain elevated and volatile amid the ongoing U.S. conflict with Iran, which has effectively closed the Strait of Hormuz—a chokepoint through which roughly 20% of global oil supply typically transits.

Higher oil prices have raised costs for everything from gasoline to shipped goods, fueling inflation that has been squeezing households and businesses.

Higher inflation has also been a problem for the Fed, which is aiming to bring inflation down to a 2% rate.

The rate of inflation currently exceeds 3% by a considerable margin, and Wall Street anticipates that the Federal Reserve will implement a rate hike before year-end to temper the pace of price increases.

According to CME FedWatch, investors are pricing in a 66% probability that the central bank will raise its benchmark rate at its forthcoming September meeting.

The Fed will receive further inflation data ahead of the meeting.

In the meantime, it is receiving updates on the labor market this week.

On Tuesday, the government reported that U.S. job openings edged up slightly in July.

A more comprehensive monthly report for August is scheduled for release on Friday.

European markets experienced a downturn, whereas their Asian counterparts delivered a divergent performance.
