Maritime traffic through the Strait of Hormuz reached its highest level since the recent conflict between Iran, the United States, and Israel on June 22, with 36 commodity-carrying vessels transiting the waterway. Data from the maritime tracking firm Kpler indicates this surge represents nearly one-third of pre-war daily traffic levels, which typically hovered around 120 ships per day.
Why is Strait of Hormuz traffic volatile?
The Strait of Hormuz remains a central point of global energy security, historically accounting for roughly one-fifth of the world’s oil and gas exports. According to Kpler, daily traffic dropped to fewer than 10 vessels following Iran’s decision to close the waterway on March 1, 2026, as a retaliatory measure against joint U.S.-Israeli military actions. While a June 14 memorandum of understanding (MoU) between Washington and Teheran briefly stabilized the route, traffic remains sensitive to regional escalations. Iran announced a new closure of the strait on June 20, citing ongoing Israeli military operations in Lebanon as the primary cause.
Before the 2026 conflict, the Strait of Hormuz facilitated approximately 120 commercial transits every day. Current levels, while recovering, remain significantly below that pre-war baseline.
How will the strait be managed in the future?
The future governance of the waterway is a primary subject of current diplomatic negotiations in Switzerland. According to Iranian chief negotiator Mohammad Bagher Ghalibaf, as reported by Teheran state media on June 23, Iran intends to manage the strait under its own interpretation of international law, asserting that the route will not return to pre-war operational conditions. This position stands in contrast to the status quo maintained by international shipping coalitions prior to the February conflict. Observers note that the next two months of diplomatic talks will determine whether this claim is codified into a lasting maritime agreement.
What are the current shipping trends?
Shipping data shows a clear upward trend in the post-MoU period. Since June 15, the average number of daily commodity vessels—including oil tankers, liquefied natural gas (LNG) carriers, and dry bulk ships—has risen to 21. Over the five-day period ending June 22, that average increased further to 27 ships per day. Kpler analysts suggest that these figures likely undercount the actual number of vessels, as maritime trackers often detect ships with a delay.

Frequently Asked Questions
Why is the Strait of Hormuz considered a vital chokepoint?
The strait is the world’s most important oil transit chokepoint. Historically, it carries about 20% of the world’s total oil and gas production.
How does the recent MoU affect shipping?
The June 14 agreement between Washington and Teheran provided a framework to resume shipping, leading to an increase from fewer than 10 ships per day to an average of 21–27 ships per day as of late June.
Is the strait currently open to international trade?
The status remains fluid. While traffic resumed following the June 14 MoU, Iran announced a closure on June 20, 2026, in response to regional military developments.
