Wall Street closed lower on Wednesday, March 4, 2026, as concerns persisted regarding the escalating conflict in Iran and its potential impact on oil prices. Despite optimistic comments from Donald Trump regarding progress in the region and promises of security in the Strait of Hormuz, the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all experienced declines.
The Dow Jones Industrial Average finished the day down 1.61% at 47,954 points, while the S&P 500 fell 0.56% to close at 6,830 points. The Nasdaq Composite saw a more modest decline, dropping 0.26% to 22,748 points.
President Trump stated on Wednesday that the United States is “in a highly strong position on the war front,” and the White House announced that U.S. Forces had struck more than 2,000 targets and were advancing toward “total and complete control of Iranian airspace,” according to Yahoo Finance.
Concerns about supply disruptions eased somewhat after Trump announced the U.S. Would offer “political risk insurance” and naval escorts for ships transiting the Strait of Hormuz, though damage to infrastructure and tankers in the region has renewed anxieties.
The conflict has similarly impacted energy markets, with the national average for diesel reaching its highest level of the year at $3.25 per gallon on Thursday, March 5, 2026, a $0.27 increase from the previous week, according to data from AAA shared by Yahoo Finance.
Diesel prices rose $0.41 during the same period, reaching $4.16 per gallon, the highest level since 2023.
Looking at monetary policy, economists at Bank of America, Aditya Bhave and Stephen Juneau, have indicated that tariffs have contributed approximately 50 basis points to underlying PCE inflation, “but that represents only half of the Fed’s inflation problem,” they wrote in a note to clients, as reported by Yahoo Finance. More concerning, they added, is the stickiness of inflation in the services sector, which “warrants caution from the Fed.”
Should the Fed continue easing with deeper rate cuts, the central bank would risk consolidating a 30-50 basis point overshoot in inflation, Bhave and Juneau wrote.
Traders currently estimate a 97.3% probability that the Fed will leave the target rate unchanged at 3.5% to 3.75% at its next meeting in March, and continue to expect between 25 and 50 basis point cuts by year-conclude.
