POLICY WIRE — New York, USA — Stocks ended the day significantly lower as escalating U.S. military actions against Iran led to a spike in oil prices, intensifying fears of persistent high inflation. A pronounced sell-off in the bond market further exacerbated the pressure on equities.
The S&P 500 index recorded a 0.7% decrease. The Dow Jones Industrial Average saw a 0.8% drop, and the Nasdaq composite index fell by 1%. This marks the third consecutive day of losses for the major indices.
This lackluster beginning to September follows a somewhat unstable yet predominantly positive August for Wall Street. Despite the monthly gains across all major indices in August, concerns regarding escalating prices, government debt, and the repercussions of global conflicts on both the U.S. and the global economy persist.
Technology stocks notably dragged the market down. Nvidia shares declined by 1.5%, Amazon shares fell 1.9%, and Advanced Micro Devices shares dropped 2.4%. The substantial market capitalizations of these companies exert a greater influence on the market direction, and their growth, particularly in the artificial intelligence sector, has been heavily dependent on borrowing, which becomes costlier as interest rates rise.
The surge in oil prices contributed to the downward trend in stocks.
A significant portion of the ongoing pressure on Wall Street stems from the continuous sell-off in U.S. government bonds. The yield on the 10-year Treasury, which often affects mortgage rates, increased to 4.79% from 4.75% the previous day. This yield was as low as 4.20% at the start of 2026.
The yield on the 2-year Treasury, which closely mirrors expectations for Federal Reserve actions on interest rates, rose to 4.39% from 4.34% the previous day. This represents a notable increase from approximately 3.50% at the beginning of 2026.
Bond yields, which move inversely to bond prices, increase as bond prices decrease. Rising yields indicate that investors are seeking higher returns from Treasurys due to the increased risk. The growing U.S. debt underscores this risk.
The U.S. national debt exceeded $40 trillion two weeks ago, a striking milestone as defense expenditures and interest on the expanding deficit constitute a substantial portion of federal spending. The bond sell-off is a global phenomenon, with other nations also grappling with similar economic pressures.
Higher yields on bonds suggest increased borrowing costs for mortgages and a wide array of other loans. Elevated borrowing costs typically dampen investments, including stocks, while making it more challenging for businesses to expand.

Oil prices have been a major factor in the pressure on inflation, bond yields, and the broader stock market. The price of Brent crude, the international benchmark, increased by 4.6% to settle at $94.65. U.S. oil prices rose by 5.2% to settle at $90.22 per barrel—the first time it closed above $90 in over a month.
Energy costs remain elevated and volatile due to the ongoing U.S. conflict with Iran, which has effectively closed the Strait of Hormuz, a critical route through which 20% of the world’s oil is typically transported.
The increase in oil prices has driven up costs for various goods, from gasoline to shipped products, fueling inflation that has been burdening households and businesses.
Higher inflation has also posed a challenge for the Federal Reserve. The inflation rate is well above 3%, and Wall Street anticipates that the Fed will raise interest rates before the end of the year in an attempt to bring inflation down to its 2% target. Investors are estimating a 66% likelihood that the central bank will increase its benchmark interest rate at its upcoming September meeting, according to CME FedWatch.
The Fed will receive additional updates on inflation before the meeting. In the meantime, it is monitoring the job market this week. On Tuesday, the government reported a slight increase in U.S. job openings in July. A more comprehensive monthly report for August will be released on Friday.
In total, the S&P 500 declined by 54.67 points to 7,631.47. The Dow dropped by 419.02 points to 52,766.88, and the Nasdaq fell by 271.11 points to close at 26,099.77.
Markets in Europe experienced declines, while markets in Asia showed mixed results.
