Brent crude nears $100 a barrel as U.S.-Iran tit-for-tat strikes stoke supply worries

On September 9, the U.S. military conducted airstrikes on five Iranian crude oil tankers, as reported by CENTCOM. The attacks came in response to two ballistic missile strikes launched by the Islamic Revolutionary Guard Corps (IRGC) against a U.S. Navy warship over the past two days. Despite the attacks, the U.S. warship managed to evade the threats and continued its patrol in the region without any casualties among American personnel.

U.S. Secretary of State Marco Rubio stated that Iran persistently attempts to hit U.S. naval ships, and each attempt results in the destruction of crude oil tankers. On September 5, U.S. forces had already targeted and destroyed three Iranian oil tankers, dropping numerous munitions that caused catastrophic damage and fires.

The series of attacks has escalated the conflict, with Iran warning that it could make the enforcement of the U.S. blockade more dangerous and expensive by targeting not only commercial tankers but also U.S. warships and vessels supporting the blockade. Iran's strategy could be to make the economic cost of enforcing the blockade politically and financially unfeasible.

For years, Iran has relied on sanctions evasion, ship-to-ship transfers, and opaque shipping networks to maintain oil exports despite U.S. restrictions. The U.S. has now demonstrated its readiness to attack vessels it considers part of this network. Iran, in turn, has shown its willingness to challenge the U.S. military presence protecting the blockade, leading to a dangerous cycle of escalating tensions.

The Strait of Hormuz, the key maritime gateway for Gulf oil exports, has become central to the confrontation as shipping traffic has slowed due to increased concerns about the waterway potentially becoming inaccessible to commercial shipping.
