Oil prices jumped and stock futures fell as new tensions between the United States and Iran raised concerns about supply through the Strait of Hormuz.
Oil prices went up and stock futures fell on Sunday evening as new tensions between the United States and Iran worried global markets, especially around the key Strait of Hormuz.
On Monday, oil prices rose more than 5% as fears grew that the temporary ceasefire between the two countries could fall apart. The concern increased after the U.S. seized an Iranian cargo ship, while ship movement through the strait remained mostly limited.
June Goh, a senior analyst at Sparta Commodities, said the situation in the strait remains tense. She noted that within 24 hours of it being declared open, some tankers were fired upon by Iran’s Islamic Revolutionary Guard Corps, making shipping companies more cautious. She also pointed out that around 10 to 11 million barrels of oil per day are still not reaching the market.
U.S. crude oil jumped over 7% to around $90 per barrel, and Brent crude rose about 5% to nearly $95. Other fuel prices also went up. Wholesale gasoline increased by more than 4%, heating oil futures climbed 7%, and natural gas prices saw a smaller rise of about 2%.
These sharp movements come after weeks of uncertainty, with markets reacting almost daily to changes between conflict and calm. While U.S. stock markets had recently recovered earlier losses, oil prices have stayed high, making fuel more expensive and adding pressure on inflation. The United States confirmed on Sunday that it had taken control of an Iranian ship accused of breaking its blockade. In response, Iran said it would take action and also stepped back from planned talks with the U.S. before the current two-week ceasefire ends.
Both sides continue to place restrictions in the region. The U.S. has kept its blockade on Iranian ports, while Iran has repeatedly changed its stance on the strait. Before the conflict began nearly two months ago, the route carried about one-fifth of the world’s oil supply.
Even with the tension, more than 20 ships passed through the strait on Saturday, carrying oil, gas, metals, and fertilizers. This was the highest number of vessels seen in the area since early March.
As tensions continue to rise and markets remain on edge, Business Fortune will keep a close watch on how these tensions could shape global energy prices and economic stability.
