Iran Blocks Strait of Hormuz and Dow Loses 200 Points
Stocks dipped on Monday as Iran continues to block the Strait of Hormuz and oil prices rise sharply.
Quick overview
- Iran's reported blockage of the Strait of Hormuz led to a nearly 2% increase in Brent crude oil prices and a 0.4% decline in the Dow Jones Industrial Average.
- Mixed reports from the Middle East regarding Iran's actions have created volatility in oil prices and stock indices.
- U.S. President Trump announced 'Project Freedom' to use military force to ensure safe passage for cargo ships in the region.
- While McDonald's and 3M saw significant declines, major tech companies like Apple and Salesforce experienced gains amid investor uncertainty.
Iran media reported that they were blocking the Strait of Hormuz and turning ships back, and the news pushed oil prices higher and caused the Dow Jones Industrial Average to lose 208 points Monday.

Brent crude oil prices jumped by nearly 2% Monday and West Texas Intermediate gained 1.49% on news that Iran was blocking off the Strait of Hormuz. Stock indices fell as a result, with the Dow decreasing by 0.4%. The Nasdaq Composite remained mostly flat, but the S&P 500 ticked down 0.1%.
Reports are mixed coming out of the Middle East for now, with some saying that Iran fired on a U.S. warship, and others saying that a ship was simply turned away. The increasing tensions caused prices to fluctuate wildly, and there may be a stronger knock down effect on stocks as the day progresses.
Iran Instability to Shake Stock Market
As long as the Strait of Hormuz remains contested, U.S. stock futures are going to fluctuate. A state of potential war creates uneasiness among investors, and the Fear and Greed Index tends to move toward fear when this happens. For now, that index is weighted toward Greed, but if the conflict worsens, then there is likely to be a quick shift toward Fear. That would create intense selling pressure on the market and leave riskier stocks with less support.
Brent crude oil is now up to $110 per barrel, remaining close to its highest point since the conflict began. The cost of oil is one of the biggest factors for stock price fluctuations recently, hurting market stability and creating hesitation among investors.
U.S. President Donald Trump announced Sunday that he would be using the military to free cargo ships in the region around the Strait of Hormuz. This operation, called “Project Freedom,” is designed to free up commerce for the area, specifically for countries not directly involved with the fighting.
McDonald’s (MCD) and 3M (MMM) led the Dow’s biggest declines, losing 2.37% and 2.74% respectively. McDonald’s stock is dropping ahead of the quarterly report as investors worry about their rising costs. 3M is down due to a poor quarterly showing in their most recent report.
The biggest winners on the Dow for the day so far are mostly major tech companies. Apple (AAPL) has 3.24% in gains and Salesforce (CRM) is up 4.13% thanks to continued support for tech stocks. These stocks have performed well despite the CBOE Volatility Index showing increasing fear among investors. AI stocks and the tech market look like safe bets amid a round of strong earnings reports this season.
