Strait of Hormuz Traffic Plummets Amid Ongoing Iran Conflict
Ship traffic through the crucial Strait of Hormuz has significantly declined four weeks into the ongoing conflict involving Iran. On March 26, only six vessels, including four bulk freighters and two liquefied petroleum gas carriers, successfully navigated the waterway. This marks a stark contrast to the average of nearly 60 commercial vessels that transited daily in 2025. Over the past week, only 39 vessels crossed the strait, raising concerns about the implications for global oil supply and economic stability.
The Iranian government has attempted to establish a tolling system for ships passing through the strait, proposing fees as high as $2 million per voyage. However, this initiative has not resulted in an increase in maritime traffic. Additionally, Iran has announced that vessels from “hostile” nations would be barred from transiting the waterway, further complicating the situation. The effective closure of the Strait of Hormuz has emerged as a critical issue for the global economy, as it is the world’s busiest oil chokepoint. The disruption is leading to a significant shortfall in global petroleum supply, driving fuel prices higher and forcing oil-producing countries in the region to reduce their output by millions of barrels per day.

Challenges in Monitoring Vessel Movements
Despite the apparent decline in traffic, it remains challenging to ascertain the exact number of vessels navigating the strait. Many ships deactivate their Automatic Identification System (AIS) signals while traversing the waterway, only reactivating them once they are safely beyond Hormuz. This practice complicates tracking efforts and raises questions about the actual volume of maritime activity in the region. Satellite imagery, which could provide additional insights, is often delayed, further hindering accurate vessel observation.
Recent reports indicate that a Greek shipping company, Dynacom Tankers Management Ltd., has managed to send at least three tankers through the strait during this tumultuous period. This development suggests that some vessels may still be managing to navigate the waterway despite the heightened risks and restrictions. Bloomberg has initiated monitoring efforts to track vessels that disappear from the Persian Gulf and those that reappear in waters beyond Hormuz, aiming to capture data on ships that may be turning off their transponders.
As tensions escalate, with Iran and Israel exchanging missile fire and incidents of drone strikes reported in Gulf states, the situation in the Strait of Hormuz remains precarious. Saudi Arabia has intercepted drones and missiles aimed at Riyadh, while alerts have been triggered in Doha, and Kuwaiti ports have sustained damage from drone attacks. Israel has responded by intensifying its military operations against Iranian infrastructure, further complicating the maritime landscape in this vital region.
