Oil prices saw a significant jump and the threat level for shipping through the Strait of Hormuz was elevated to its highest designation, 'severe,' following US airstrikes against Iran. These actions, coupled with renewed US sanctions on Iranian crude sales, have intensified fears that the fragile truce between Washington and Tehran is collapsing, potentially disrupting Middle East energy supplies.
US Strikes Respond to Vessel Attacks
The US military confirmed that its strikes were a direct response to recent Iranian attacks on three commercial vessels navigating the Strait of Hormuz, a critical artery for global oil shipments. These incidents included damage to a Saudi crude tanker and an attack on a Qatari liquefied natural gas (LNG) tanker, which reportedly faced an explosion risk after a fire erupted in its engine room. The crew of the LNG vessel was safely evacuated.
Market Reaction and Sanctions
The escalating tensions pushed Brent crude futures close to $76 a barrel, with prices up 1.9% to $75.54 a barrel. US West Texas Intermediate (WTI) crude also gained 1.9%, reaching $71.81 a barrel. Both benchmarks had already climbed approximately 3% on the preceding day, with post-market activity showing an almost 6% increase in oil prices.
These latest developments have effectively undone the uneasy détente established in late June, which had seen Washington and Tehran agree to reopen the Strait of Hormuz after a three-month conflict that severely constrained global energy supplies. On Tuesday, the White House revoked the general license that had allowed Iran to sell oil under that agreement, labeling Iran's actions in the waterway as "wholly unacceptable" and warning of further consequences.
Strait of Hormuz Threat Level Raised
The Joint Maritime Information Center (JMIC), led by the US Navy, elevated the transit threat level for the Strait of Hormuz from "substantial" to "severe" after the attacks. This marks the first such designation since June 15. The JMIC issued a warning that deliberate hostile action is now probable and advised mariners to exercise extreme vigilance, citing ongoing naval deployments, congestion along transit routes, and increased hailing incidents by Iran's Islamic Revolutionary Guard Corps.
Despite some recovery in shipping traffic over the past week, volumes through the strait remain significantly below pre-war levels, operating at only one-third to one-fifth of previous capacity. Before the conflict began in February, the waterway was responsible for transporting roughly one-fifth of the world's total oil and gas supplies.
