US Strikes Iran After Ship Attacks in Strait of Hormuz

The United States has launched a series of airstrikes against Iran in retaliation for attacks on commercial vessels in the Strait of Hormuz. According to a statement from U.S. Central Command (CENTCOM), the strikes were conducted to "impose heavy costs" on Iran after its targeting of commercial shipping crewed by innocent civilians in international waterways. This development has been characterized as a clear violation of the fragile memorandum of understanding (MOU) on maritime security reached between Washington and Tehran last month.

Tensions escalated following attacks by Iran's Islamic Revolutionary Guard Corps on three commercial tankers transiting the Strait of Hormuz. These attacks are reportedly a continuation of increasing harassment of maritime traffic in the region in recent weeks. Hours before the airstrikes, the U.S. Treasury Department revoked a waiver that had allowed Iran to sell oil and petrochemicals. This waiver was a key benefit for Iran under last month's ceasefire agreement, effectively cutting off a significant revenue source for Tehran. Iran's Foreign Ministry condemned the U.S. decision as a violation of the MOU, stating it would take all necessary steps to safeguard its national interests.

U.S. officials indicated that the airstrikes targeted Iranian air defense systems, coastal surveillance systems, surface-to-air missiles, anti-ship cruise missile launch sites, drone launch sites, and port facilities. Iranian state media reported explosions in the southern parts of the country. This military retaliation risks undermining diplomatic efforts aimed at restoring security in the Strait of Hormuz, one of the world's most critical maritime chokepoints.

These latest developments underscore the fragility of the ceasefire reached last month, which followed months of military confrontation that began in February 2026 with an air war launched by the U.S. and Israel against Iran. The ongoing tensions in the region pose serious risks to global energy supply chains and international maritime trade. The Strait of Hormuz holds strategic importance as approximately one-fifth of the world's seaborne oil trade and 20% of its liquefied natural gas (LNG) trade passes through this vital waterway.

The attacks triggered an immediate and significant reaction in global commodity markets. Brent crude, the international benchmark for oil prices, surged by over 5.5% to nearly $76 per barrel, while the U.S. benchmark, West Texas Intermediate (WTI), also climbed more than 5% to above $72 per barrel. Markets are maintaining a cautious stance amidst concerns of further escalation in the region and potential disruptions to maritime traffic in the Strait of Hormuz. Analysts warn that this situation could exacerbate global inflationary pressures and influence central bank monetary policy decisions.
