U.S. financial markets opened lower Monday following renewed military action by American forces against Iran, triggering concerns over energy supply disruptions amid a protracted conflict in the Middle East. The S&P 500 index declined 0.4 percent, while the Dow Jones Industrial Average dropped 348 points, or 0.7 percent, and the Nasdaq Composite fell 0.3 percent by mid-morning Eastern Time. Losses were broad-based across most sectors, with energy stocks providing a rare bright spot. Exxon Mobil and Chevron shares rose 2.9 percent and 3 percent respectively.
The moves came after U.S. forces targeted Iranian rocket launchers near the Strait of Hormuz on Sunday. The waterway is strategically vital, accounting for roughly 20 percent of global oil shipments. The regional tensions escalated further when the United Arab Emirates reported intercepting an Iranian drone over its territorial waters on Monday. These developments mark a sharp increase in hostilities after a relative lull during the six-month-long U.S.-Iran conflict.
Oil prices responded swiftly to the escalating violence, with the price of Brent crude rising 3.2 percent to $90.91 per barrel. Over the past month, prices have fluctuated between $72 and $102 per barrel amid shifting market sentiment and ongoing concerns about supply disruptions. The impact on fuel costs is evident in U.S. retail gasoline prices, which have remained above $4 per gallon every day this August, setting a record for the highest average monthly pricing. This surpasses previous peaks recorded even during the significant supply chain constraints of the COVID-19 pandemic in 2022.
The sustained elevation in energy prices has compounded inflationary pressures that have weighed on consumer spending and economic confidence. Inflation continues to run significantly above the Federal Reserve’s 2 percent target, hovering above 3 percent. In response, the Fed is widely anticipated to implement at least one more interest rate hike before year-end, aiming to rein in price growth without severely damaging the labor market.
Bond markets reflected these dynamics as well. The yield on the two-year U.S. Treasury note, a key indicator of investor expectations for Fed policy, held steady at 4.34 percent near Monday’s open, up sharply from around 3.5 percent at the start of the year. The yield on the 10-year Treasury note edged up to 4.76 percent from 4.73 percent on Friday, approaching levels last seen two weeks ago when the previous administration intervened in the bond market.
Labor market data remains mixed, with signs of weakening despite resilience over recent months. July payrolls unexpectedly contracted by 23,000 jobs, and revisions to May and June figures reduced previously reported employment gains by 103,000 positions. The U.S. government is set to release August jobs data later this week, which will be closely watched for indications of whether rising interest rates and inflation pressures are beginning to weigh more heavily on employment.
