On April 3, 2026, the CMA CGM Kribi — a container ship owned by France's CMA CGM, the world's third-largest shipping company — became the first vessel tied to Western Europe to transit the Strait of Hormuz since Iran's de facto blockade began at the outbreak of war on February 28.
How the Transit Worked
CMA CGM coordinated the passage directly with Iranian maritime authorities. As the vessel approached Iranian territorial waters, it changed its AIS (Automatic Identification System) destination field to "Owner France" — broadcasting its French nationality to IRGC naval forces monitoring the strait. The ship navigated the approved corridor between the islands of Qeshm and Larak, passing through Iranian territorial waters without incident.
Strategic Significance
The transit was a calculated diplomatic signal. Since the IRGC declared its "Not one litre of oil" blockade in mid-March, tanker traffic through the strait had dropped roughly 70%, with 150+ vessels anchored in international waters waiting for safe passage. Oil prices had spiked above $100/barrel, threatening a global recession.
Iran's decision to allow a French ship through — while continuing to threaten American, British, and Israeli-linked vessels — exploited a fault line in the Western coalition. France had spent the previous week working to soften a United Nations Security Council resolution that could have authorized forceful action to reopen the strait. By rewarding French diplomatic restraint with commercial access, Iran created a direct material incentive for France to break from the U.S.-led military approach.
The tactic echoed classic divide-and-conquer diplomacy: make cooperation with the dominant military power costly, and cooperation with the adversary profitable. If France could ship goods through Hormuz while American-allied vessels could not, the economic pressure would fall disproportionately on the nations most committed to the war — undermining the coalition from within.
Iran's Selective Passage System
The French transit was part of a broader Iranian system for controlling Hormuz access. The IRGC assigns each nation a "friendliness ranking" of 1-5, requiring vessel operators to submit documentation (ownership, flag, cargo, crew, destination) for geopolitical vetting. Approved ships receive a VHF-broadcast passcode and IRGC Navy escort. Nations previously granted passage included China (from March 4), Pakistan, India, Turkey, and Russia. The IRGC charges tolls starting at $1 per barrel for oil tankers, payable in Chinese yuan or stablecoins (Bloomberg).
Foreign Minister Araghchi stated Tehran had been "approached by a number of countries" seeking safe passage, and that "this is up to our military to decide."
Macron's Same-Day Criticism
The transit coincided with Macron's sharpest criticism of Trump's war approach: "There are those who advocate for the liberation of the Strait of Hormuz by force through a military operation, a position sometimes expressed by the United States. This was never the option we have supported because it is unrealistic." He urged Trump to "be serious" and added: "This is not a show. We are talking about war and peace and the lives of men and women." France had joined Russia and China in blocking a Bahrain-drafted UN Security Council resolution authorizing "all necessary means" to reopen the strait.
European Coalition Refusal
Multiple NATO allies rejected Trump's call for a naval coalition to force Hormuz open. Germany's defense minister said there would be "no military participation." The UK's Starmer ruled out a NATO mission. Spain said "absolutely not." France confirmed it "would not send ships." Instead, Starmer was organizing a 40-nation coalition — without the U.S. — focused on diplomatic measures and post-conflict demining.
