The partial reopening of the Strait of Hormuz has led to a cautious resurgence in oil shipments from the Persian Gulf, but uncertainty remains high among shipowners and producers in the region. The narrow waterway, a critical global energy passage supplying roughly 20% of the world’s oil, saw limited tanker traffic following a preliminary agreement between the United States and Iran aimed at reducing hostilities and restoring navigation.
In the days following the deal, maritime data indicated a gradual increase in vessel movements through the strait, with 25 ships, including 14 oil tankers, reported on one day. However, regional tensions and occasional bursts of violence led to fluctuations in transit numbers, with a decline observed shortly thereafter before volumes rebounded again. Estimates suggest that about 5.1 million barrels of oil per day have been flowing through the strait recently, a notable rise from approximately 2.9 million barrels per day in May but still only about a quarter of pre-conflict levels. Much of the oil exports, now approaching nine million barrels daily for the Persian Gulf as a whole, are moving through alternative ports that bypass the strait altogether.
Despite the tentative increase in activity, many in the shipping and energy sectors remain cautious. Shipowners seek reassurances regarding crew safety and the acquisition of war risk insurance before fully committing to transit through the waters, which have been heavily mined during the conflict. Clearing the strait of mines and ensuring secure navigation are expected to take several weeks, delaying a full recovery of shipping flows.
Oil producers in the Gulf, including Saudi Arabia’s Saudi Aramco and Kuwait Petroleum, expressed their readiness to scale up output but emphasized the need to see sustained vessel movement through the strait. The recent weeks of disruption have accelerated efforts to reduce reliance on this vulnerable route. Saudi Aramco’s chairman, Yasir O. Al-Rumayyan, indicated plans to expand global storage capacity, while Kuwait’s CEO, Sheikh Nawaf Al Sabah, confirmed talks with Saudi Arabia and the United Arab Emirates to develop alternative pipeline infrastructure to transport oil beyond Iran’s maritime reach.
Infrastructure initiatives are underway, though completion is not imminent. The UAE is progressing on a pipeline project targeting a 2027 opening that would double its crude export capacity outside the strait. Meanwhile, Kuwait and its Gulf neighbors explore new routes to stabilize export capabilities amid ongoing geopolitical risk.
Analysts point to the broader geopolitical environment as the main determinant of market stability. Negotiations over Iran’s nuclear program remain unresolved and are unlikely to conclude quickly, extending the elevated risk for maritime navigation and regional oil exports. Experts warn that any resurgence of conflict would severely disrupt recovery efforts and undermine progress made toward resuming energy flows.
The fragile détente has initiated movement but has yet to restore normalcy. The coming months are expected to involve a cautious, uneven recovery marked by continuing uncertainty for global energy markets and regional stakeholders alike.
