Oil prices rise on Friday after Iran says it has stopped two vessels trying to exit the Strait of Hormuz, adding to concerns about global energy supplies. The reports come amid heightened regional tensions after a drone attack on ships in a Mediterranean Egyptian port earlier this week. According to Iran, its forces intervened to halt the two vessels and also caused four other tankers to turn back, Reuters notes. The developments are described as a signal that shipping traffic through a key chokepoint remains vulnerable to disruption. While details about the stopped vessels and the basis for the Iranian actions are not specified in the available summaries, the news is presented as part of a broader security situation affecting maritime transport and trade routes. Oil traders respond to perceived risks to supply and transit, which contributes to price movements. The reports attribute the initial market reaction to Iran’s statement about intervening in traffic at Hormuz.
