Trump's toll-payer order targets allied ships

3 min read

Trump ordered the Navy to stop any vessel that paid Iran's Hormuz toll, a list that includes French and Japanese ships whose governments refused to join the blockade.

Key takeaway

The blockade threatens to interdict vessels from allies who refused to join it.

France's CMA CGM Kribi and Japan's Mitsui OSK both paid Iran's Hormuz toll in yuan in early April. Under Trump's toll-interdiction order, both vessels, and potentially others from the Philippines and UAE, are targets for US Navy interception in international waters.

CENTCOM's operational order does not include this provision. Whether that reflects a deliberate decision to avoid the most explosive implications of the tweet, or a narrower military reading of the order, is unknown. The gap creates daily legal exposure: any officer who intercepts a French or Japanese vessel under the presidential order, or any officer who does not, acts without clear authority.

The blockade was designed to pressure Tehran. It has instead handed Paris and Tokyo a grievance against Washington. The EU had already rejected Trump's suggestion of a US-Iran "joint venture" on toll collection, citing UNCLOS transit passage rights. France and Japan are now members of the UK's reopening coalition while also appearing on the US interception list for having paid Iran's fees.

Deep Analysis

In plain English

Iran has been charging ships a fee , called a toll , to pass through the strait of Hormuz. Some European and Asian companies paid this toll to keep their goods moving, including a French shipping company (CMA CGM) and a Japanese energy firm (Mitsui OSK). Trump's social media post said the US Navy should stop any ship that had paid Iran this toll , which would include those French and Japanese vessels. France and Japan are US allies who refused to join the blockade. CENTCOM's actual military order did not include this instruction. So right now, there is a gap between what Trump said should happen to allied ships and what the US military is actually doing. That gap has not been publicly resolved.

What could happen next?
  • Risk

    France could invoke UNCLOS Article 300 (good faith obligations) and file immediate ITLOS proceedings if a CMA CGM vessel is stopped, creating an international court process that would take months but generate immediate diplomatic crisis.

  • Consequence

    CENTCOM's omission of the toll-interdiction provision from its operational order leaves a daily decision gap: every officer on patrol near a toll-paying allied vessel must choose which authority to obey without clear guidance.

    Immediate · 0.88
  • Risk

    If France and Japan are both targeted as toll-payers and members of the UK's 40-nation reopening coalition, the US blockade and the UK coalition are in direct operational conflict over the same vessels in the same waterway.
