According to reports published by Bloomberg, the escalation of the regional conflict, launched with the direct involvement of the United States and the Israeli regime, has delivered an unprecedented shock to international energy markets. In their initial response, oil and refined product markets experienced a rapid and significant surge. Diesel (gasoil) futures on the Intercontinental Exchange rose by up to 17%, reaching their highest level in two years at the start of trading. The increase reflects deep concern among traders over sustained disruptions to the supply of key fuels.

The geo-energy significance of the Strait of Hormuz has been decisive in these developments. Based on data from ship-tracking and analytics firm Kpler, cited by Bloomberg, roughly 10% of global diesel trade and 20% of jet fuel (kerosene) pass through the Strait of Hormuz. This narrow corridor is a vital artery for transporting energy from major Middle Eastern producers to markets in Asia, Europe, and even the United States. Any disruption along this route is immediately reflected in refined product prices and global shipping costs.

In recent days, the actions and capabilities of the armed forces of the Islamic Republic of Iran to restrict maritime traffic in the Strait of Hormuz have emerged as a key variable in the war equation. Relying on its geographic position, asymmetric naval capabilities, and coastal deterrence tools, Tehran has signaled that if hostilities continue, it can seriously disrupt energy flows. Even a credible threat of a full blockade—without actual implementation—has been sufficient to heighten geopolitical risk and drive prices sharply higher.

Bloomberg also warns that if the Strait of Hormuz were to be fully closed, Middle Eastern oil producers would likely be able to continue production for “a maximum of 25 days,” as storage constraints would eventually force them to halt output. Such a scenario would not only reduce global crude oil supply but also create severe shortages in refined products such as diesel and jet fuel.

In this context, the Strait of Hormuz has effectively become a “geo-economic weapon” in Iran’s hands—an instrument capable of altering the cost balance of the war. Rising energy prices would place inflationary pressure on consuming economies and increase the political and economic costs of prolonging the conflict for those who initiated it. From this perspective, Iran’s ability to threaten or restrict this passage will be an influential factor in the strategic outcome of the war and in the calculations of international actors.
