Tanker risks in the Strait of Hormuz are increasing due to Iran's threats to block unauthorized routes, leading to more attacks and intimidation against vessels trying to pass through. Last week saw the highest number of attacks since the conflict began, reducing tanker traffic to its lowest point in two months. Iran’s Revolutionary Guards plan to use missile and drone attacks or small boats to scare off ships attempting to navigate alternative routes, according to a senior regional official close to Tehran.

Story summary
Iran has warned it will block shipping routes through the Strait of Hormuz that it hasn’t authorized, increasing risks for tankers transporting critical shipments. Last week saw the highest number of attacks on tankers in the region since the start of the conflict with Iran, resulting in a significant decline—more than two months’ lowest—in vessels attempting to navigate through the strait. According to sources close to Tehran, both political leaders and the Revolutionary Guards have agreed on this plan as part of their strategy to maintain control over the strategic waterway. A senior diplomat briefed by Tehran emphasized that Iran plans to use missile, drone attacks, or small boats to intimidate ships away from unauthorized routes, implementing what is described as a "policy of fear and threats."
