Tensions between the U.S. and Iran have dangerously escalated following the latest round of American strikes against Iranian military targets and Tehran’s swift retaliation, which included missile attacks on two Emirati oil tankers in the Strait of Hormuz and alerts in Bahrain. This renewed conflict has shattered a recent ceasefire agreement, leading to a sharp increase in war risk premiums for shipping through the critical waterway and impacting global oil prices.
In a dramatic escalation of tensions, the United States has concluded its latest series of strikes targeting Iranian military assets for the third consecutive night. This action comes amidst retaliatory attacks by Tehran, which saw two Emirati oil tankers hit in the critical Strait of Hormuz and missile alerts triggered in Bahrain.
U.S. Central Command (CENTCOM) confirmed the completion of its recent five-hour mission, which aimed at degrading Iran's capacity to threaten commercial shipping. The strikes targeted various Iranian military facilities, including coastal defense systems, missile and drone sites, and naval capabilities. These operations followed a directive from former President Trump to reinstate a blockade on Iran in the strait and proposed a 20% toll for vessels traversing the vital energy waterway.
Iran swiftly responded to the American offensive with its own strikes against Gulf nations. The United Arab Emirates Defense Ministry reported that two of its national tankers, the Mombasa and AI Bahiyah, were struck by Iranian cruise missiles in Omani territorial waters within the southern lane of the Strait of Hormuz. The attack tragically resulted in the death of one Indian crew member on the Mombasa, injured eight others, and caused significant damage from fires aboard both vessels. The UAE ministry affirmed its highest level of readiness to counter any threats to its security.
Bahrain, host to the U.S. Navy's Fifth Fleet, also experienced renewed attacks, with missile-alert sirens sounding early Tuesday morning as Iran continued its retaliation, according to the Associated Press.
The intensifying conflict is significantly impacting maritime traffic. Data from Kpler indicates that confirmed crossings through the Strait of Hormuz declined by approximately 52% week-on-week between July 10 and 12. Shipping patterns are reverting to "more defensive routing," characterized by increased use of Iranian and "dark" routes, while avoiding Omani and International Maritime Organization-authorized corridors.

Market reactions are notable: war risk premiums for transiting the Strait of Hormuz are projected to surge, prompting shipowners and charterers to delay or halt movements through the waterway. This latest escalation effectively dismantles the recent U.S.-Iran interim agreement, which had sought a 60-day pause in hostilities and the reopening of the strait for negotiations.
The renewed uncertainty over shipping in the Strait of Hormuz, a conduit for a fifth of global oil and gas, drove Brent crude prices up 2% to $85 a barrel, while U.S. West Texas Intermediate climbed 2.3% to $80 on Tuesday.
