U.S.-Iran tanker war escalates as Hormuz disruption deepens

The U.S.-Iran conflict escalated over the weekend, with Iran alleging attacks on a U.S.-operated drone boat and multiple commercial vessels in the Strait of Hormuz, according to Al Jazeera. Iran's Islamic Revolutionary Guard Corps claimed to have targeted a U.S. drone boat, which was allegedly attempting to enter a protected area, followed by a similar incident against a U.S. aircraft carrier and Navy destroyer.

The U.S. responded by striking three Iranian oil tankers in the Gulf of Oman, permanently disabling the M/T Downy and M/T Stark 1 and destroying the unladen M/T Kylo. CENTCOM later confirmed the Kylo had sunk. Defense Secretary Pete Hegseth threatened further retaliation against Iran's oil tankers, potentially impacting Tehran's energy exports.

Iran's IRGC reported attacks on three additional oil tankers and three U.S.-affiliated vessels in the strait. Iran's Foreign Ministry condemned the U.S. strikes and warned that its partners would bear responsibility for any escalation. The ongoing confrontation is intensifying pressure on already disrupted regional energy flows, with Middle East crude exports falling by 39% in August compared to January and February levels.

Diplomatic efforts continued overnight, with Iranian Foreign Minister Abbas Araghchi holding calls with Turkish and Saudi counterparts. Meanwhile, the conflict spread to other regions, including Israel launching strikes in southern Lebanon and intensifying fighting in Yemen. The ongoing tensions keep the Strait of Hormuz at the forefront of market risk, with shipping security and Gulf oil exports remaining critical drivers for crude prices and energy stocks.
