Iran To Reveal Hormuz Tolls Plan As Trump Warns of 'Very Bad Time'

Iran’s government said it will soon unveil a plan to charge commercial vessels a transit fee for passage through the Strait of Hormuz, according to Al Jazeera’s live coverage from Tehran. President Trump responded by warning Tehran of a “very bad time” if the proposal is implemented, telling Fox News the waterway “will be open” and that Iran would not be allowed to use the strait “as a weapon.”

The Strait of Hormuz carries roughly one-fifth of all seaborne crude oil and a comparable share of liquefied natural gas, according to the US Energy Information Administration. A formal toll regime — even one framed by Tehran as a navigation or pilotage fee — would amount to a new sovereign claim over an international waterway, and the enforcement mechanism behind it would determine whether the world treats the announcement as policy theater or as a maritime crisis. The closest historical reference point is the 1979–80 oil shock, when a regional rupture priced political risk directly into every barrel.

What Iran has said

The plan, as outlined in Al Jazeera’s reporting, would impose a per-vessel charge on commercial traffic transiting the strait, with the Islamic Revolutionary Guard Corps Navy serving as the collection and enforcement arm. Tehran has framed the proposal as a cost-recovery measure tied to navigation services and what officials describe as security provision in the waterway. Specific tariff levels, exemption categories, and the legal vehicle under which the fees would be assessed have not yet been formally announced.

What has been signaled, rather than published, is the intent. Iranian officials have told local media a schedule will be released “soon,” without committing to a date. The distinction matters: a tariff published in the Iranian Official Gazette and enforced by IRGCN boarding parties is a fundamentally different event from a press-conference threat. For now, the international response is reacting to the threat. Al Jazeera’s exclusive on-the-water report from the strait shows commercial traffic still moving, with IRGCN small-boat activity in the foreground.

Trump’s response

Trump’s “very bad time” line, delivered in a Fox News interview, was paired with two more consequential statements. He said the strait “will be open” and that Iran would not be permitted to use Hormuz “as a weapon.” Read as policy rather than rhetoric, those phrases commit US Navy posture: an “open” strait implies active freedom-of-navigation operations and a willingness to escort or sail through any toll-collection attempt. The Fifth Fleet’s posture in the Gulf — see our earlier coverage of the Ford Carrier Strike Group’s Presidential Unit Citation — gives that commitment operational weight.

Seoul breaks publicly

South Korea, one of the largest LNG importers transiting Hormuz, became the first major Asian buyer to publicly oppose the plan. Seoul’s oceans minister called the proposed fees a violation of international law, according to Anadolu via Middle East Monitor. The objection rests on the long-standing principle that the strait is an international waterway in which the right of transit passage cannot be unilaterally taxed by a coastal state. South Korea’s position aligns it with the US-and-Bahrain draft resolution now circulating at the UN Security Council.

China’s silence

Beijing’s posture is the policy story underneath the headlines. China is the largest buyer of Iranian crude and is the single party with the most leverage over Tehran on this question. At the UN Security Council, Chinese envoy Fu Cong criticized the US-backed Hormuz resolution without endorsing the toll plan itself, declining to back either side on the substance of the fees. See our earlier coverage of the UN resolution fight for the full procedural picture.

What Beijing has not done is more telling than what it has said. As OilPrice argued in its analysis of Beijing’s silence, China has chosen not to use its considerable economic leverage to discourage Tehran from a step that would directly tax Chinese-flagged tankers and Chinese-bound cargoes. That restraint is consistent with a longer Chinese pattern of letting Washington absorb the costs of underwriting global maritime commerce while Beijing preserves optionality on both sides. It is also consistent with Iran’s warnings of a prolonged conflict and escalating economic costs — a posture that benefits from major-power ambiguity rather than alignment.

What to watch

• Publication of a formal toll schedule in the Iranian Official Gazette, including any IRGCN enforcement rules of engagement.
• Office of Foreign Assets Control response, particularly any secondary-sanctions guidance for shippers, P&I clubs, and flag states that comply with Iranian fee demands.
• Japan, India, and Singapore — the three Asian buyers whose tanker fleets are most exposed — and whether they follow Seoul into public opposition or stay quiet like Beijing.
• Any near-miss, boarding, or seizure incident in the strait. The first IRGCN enforcement action against a non-complying vessel would convert a policy threat into a maritime crisis on the same news cycle. Reports of Washington pressure on the UAE over Lavan Island suggest the US is already pre-positioning leverage against Iranian oil infrastructure that would be the natural target if escalation runs that way.
