What actions taken by Iran led to the Dow dropping by 750 points

U.S. Stock Market Declines Amid Rising Oil Prices

By midday, U.S. equities experienced increased selling pressure as oil prices surged. This followed news that Iran had launched a missile at an oil tanker near Iraq’s coastline.

The missile attack has heightened concerns about the safety of shipping routes in the Persian Gulf, extending beyond the Strait of Hormuz. Iran previously announced the closure of the Strait of Hormuz, a crucial passageway for roughly 20% of the world’s oil and liquefied natural gas. Although President Donald Trump offered U.S. naval escorts for vessels, congestion in the area has delayed both oil and container shipments. These disruptions have driven oil prices to their highest point since June 2025.

While most financial experts do not yet believe the recent spike in oil prices will significantly accelerate inflation, they caution that prolonged disturbances could increase the risk of rising prices.

Stephen Brown, deputy chief North America economist at Capital Economics, commented, “Although the outlook is very uncertain, if West Texas Intermediate crude remains near $80 for several months before declining later in the year, the direct effect on inflation may be limited to around 0.3%.”

Market Performance and Oil Price Movements

As of 11:59 A.M. ET, the Dow Jones Industrial Average had fallen 1.57% (764.64 points) to 47,974.77. The S&P 500 dropped 0.66% (45.32 points) to 6,824.18, while the Nasdaq Composite slipped 0.3% (69.44 points) to 22,738.044. Meanwhile, West Texas crude oil soared 6.34% to $79.39 per barrel.

Multiple Factors Impacting the Markets

In addition to oil price volatility, some economists are concerned that the robust economy could keep inflation elevated.

Brown noted, “A key issue for the Federal Reserve is that the rise in oil prices coincides with other signs of increasing inflationary pressures.”

He also pointed out that tariffs and the expansion of artificial intelligence are contributing to higher production costs for IT hardware, especially memory chips. This trend is expected to push up consumer prices for technology products and smartphones this year.

According to Brown, these combined factors may prevent the Federal Reserve from reducing interest rates in 2026.

Market expectations for a rate cut remain low. The CME Fed Watch tool indicates only a 2.7% probability of a rate cut this month, less than 11% in April, and about 30% in June—each lower than the odds a month ago.

Amid these inflation concerns, the yield on the 10-year Treasury note has climbed, most recently reaching 4.138%.
