Trump Offers Gulf Investment Instead of 20% Strait of Hormuz Transit Fee, Sparking Industry Alarm
President Trump says Gulf states can replace proposed 20% Strait of Hormuz transit fee with investments in the United States, a move that leaves shipping firms and international regulators seeking clarity.
President Trump announced he would drop a proposed 20 percent “United States Reimbursement Fee” for ships using the Strait of Hormuz if Gulf states agree to make large investments in the United States, saying such deals would secure “safe passage” for vessels. The president’s statement did not specify which countries would be involved, how investments would be structured, or whether non-Gulf users of the strait would be expected to participate. Shipping companies, industry groups and the International Maritime Organization responded with concern, arguing the plan could upend decades of accepted practice for international waterways.
Trump withdraws proposed 20% transit fee
President Trump publicly shifted course a day after suggesting the United States would charge a 20 percent levy on vessels transiting the Strait of Hormuz in return for military protection. His later message replaced the fee with an offer that Gulf states provide “trade and investment deals” into the U.S. in exchange for American guarantees of maritime security. The administration has not provided legal or operational details explaining how such investments would translate into an enforceable commitment to escort or protect commercial shipping.
Gulf investment proposal leaves key details unresolved
The announcement left unanswered questions about scope and reciprocity, including whether countries outside the Persian Gulf that regularly use the strait would be asked to invest, and how investments would be measured or timed. Industry observers said there is no clear mechanism for converting private or sovereign investment into binding security guarantees for transiting ships. That lack of specificity has prompted caution among shippers already weighing operational decisions in a volatile environment.
Shipping sector warns of higher costs and precedent risks
Executives representing global shipping firms warned that monetizing transit security would raise freight costs worldwide and could invite copycat demands from other littoral states. Shipowners and trade bodies said the change would undermine long-standing norms that keep international straits open and free for navigation, and that any attempt to attach a price to passage would be “really, really problematic” for the industry. Several carriers signalled they would pause movements through the Persian Gulf until the security picture stabilizes and commercial conditions are clarified.
International Maritime Organization reiterates opposition to tolls
The International Maritime Organization, the United Nations agency that regulates global shipping, said it opposes mandatory fees for passage through straits used for international navigation and was awaiting further details about the U.S. proposal. The IMO highlighted that there is no legal basis under international maritime law to introduce compulsory tolls for transit through such waterways, a stance that industry groups echoed as they cautioned against eroding established conventions that limit unilateral levies on shipping lanes.
Iran’s response and the recent spike in maritime attacks
Iran seized on the unfolding debate by asserting that parties providing security for commercial vessels should be compensated, and by dismissing the specific 20 percent figure as excessive. The exchange came amid renewed hostilities in the region, with Iranian strikes on multiple vessels and a series of incidents that left sailors killed and others wounded. The attacks have forced maritime traffic through the strait to plummet from pre-conflict daily averages, reflecting the acute operational risk for ship operators and the fragile security calculus for Gulf littoral states.
Economic and energy market consequences of transit uncertainty
Analysts warned the dispute over the strait’s status and the prospect of charging for transit could push freight rates and global supply costs higher, feeding inflationary pressure for end consumers. The Strait of Hormuz remains a critical artery for oil and goods, so persistent attacks or a formalized system of paid protection would likely reverberate through energy markets and trade routes. Data firms tracking vessel movements reported a sharp decline in transits as carriers reroute or delay sailings to avoid exposure to hostile activity.
The president’s pivot from a direct transit levy to a proposal tied to Gulf state investment did little to resolve legal, commercial and security questions, and it highlighted how fluid policymaking can intensify uncertainty for maritime operators and regional partners alike.
