Strait of Hormuz tanker attacks escalate as IRGC orders ship to turn back

· Shipping · Iran · United Kingdom

The security situation in the Strait of Hormuz deteriorated sharply over the weekend, with UK Maritime Trade Operations reporting five separate incidents on Monday alone, including four tanker attacks and an incident in which Iran's Islamic Revolutionary Guard Corps ordered a commercial ship to turn back. The attacks mark a significant escalation since the US-Iran Memorandum of Understanding lapsed in mid-August without renewal, leading to intensified strikes and counterstrikes around the strait. Despite the attacks, Middle East oil exports have climbed to their highest levels since the start of the Iran war, as more Gulf producers resume transit through the waterway. However, logistical constraints and persistent security risks continue to cloud the outlook for sustained higher flows, with elevated oil prices suggesting logistical problems are proving as disruptive as supply constraints.

Why it matters：The escalation directly threatens a waterway carrying roughly a fifth of global oil and LNG trade, forcing shipowners to weigh higher war-risk insurance and rerouting costs against continued transit, with knock-on effects for global energy prices and freight rates.
