The partial restriction of the Strait of Hormuz following the Middle East escalation has severely reduced maritime transit through a vital energy corridor. The waterway normally handles approximately 20 percent of global crude oil and liquefied natural gas, but commercial traffic has plummeted since regional hostilities intensified on February 28.
Tracking data shows commodity vessels recorded only 201 transits between March 1 and March 31, a 95 percent drop from standard operations. Monday saw just four crossings compared to a typical peacetime average of 120. Consequently, a significant vessel backlog has accumulated, with nearly 2,500 ships currently signaled in the Gulf west of the strait, including over 360 dedicated energy carriers.
Recent navigation patterns indicate operators are utilizing an Iranian-endorsed corridor near Larak Island to bypass restricted zones. Shipping intelligence notes at least 34 commercial ships have used this route, though Iranian security officials maintain it remains inaccessible to vessels originating from opposing states. Despite the blockade, Chinaβs foreign ministry confirmed the successful transit of three domestic merchant vessels, including two ultra-large container ships that completed passage after a prior delay.
Security incidents continue to complicate regional logistics. Iranian operations recently ignited a fire aboard the Kuwaiti tanker Al Salmi at Dubai Port, which was extinguished without environmental damage. Concurrently, Iranian media confirmed strikes disabled a critical desalination facility on nearby Qeshm Island. Passage analytics reveal that 44 percent of all crossings since late February involved vessels under US, EU, or UK sanctions, a proportion that reaches 61 percent among oil and gas carriers.
The maritime blockade has also exacted a human cost. The International Maritime Organization confirms eight seafarer and port worker fatalities, ten injuries, and roughly 20,000 maritime personnel facing route diversions or contract extensions. Supply chain analysts monitor the corridor closely as markets adjust to tighter energy logistics. Sustained commercial recovery will require verified security measures and coordinated efforts to stabilize recognized shipping lanes.
