Iran charges Hormuz fees by October 31?

Prediction markets put the probability at 62%: Iran charges Hormuz fees by October 31. Currently, markets are divided (62% YES, 38% NO). Despite US objections, ambassador insists new fees to be charged to vessels transiting Strait of Hormuz..

What’s Happening

Europe is studying proposals that could permit navigational fees in the Strait of Hormuz, provided the tolls are not compulsory and win the backing of the UN's International Maritime Organization (IMO), according to plans reported on July 11. The framework surfaced as US officials pressed Tehran to issue a public statement affirming the strait is open and that shipping can pass safely. Days earlier, on July 8, Iran told the IMO that "parts of the Strait of Hormuz fall within the territorial waters of the Islamic Republic," a legal claim underpinning its bid to charge transit fees. Whether Iran formally imposes charges — the core of the question of whether iran charges hormuz fees by october 31 — now hinges on these parallel diplomatic tracks. [The Guardian, Jul 11]

Tehran has signaled clear intent to proceed. On July 5, officials said Iran "will definitely charge service fees," framing them as service levies rather than tolls, while offering exemptions to "friendly nations." Ambassador to China Abdolreza Rahmani Fazli told the World Peace Forum in Beijing that China and other partners would receive "special considerations," and cited "new arrangements" being developed with Oman. The stance directly contradicts President Donald Trump, who claimed late in June that Iran had promised not to levy charges. Analysts caution that the "friendly nations" carve-out and the disputed toll-versus-fee labeling leave the practical resolution ambiguous even if fees are announced. [Al Jazeera, Jul 5]

The structural factor determining whether iran charges hormuz fees by october 31 is whether Tehran converts its territorial-waters claim into an enforced, compulsory charge before US and European conditions are met. Washington has demanded a public "open strait" declaration, while the European framework insists any fee remain voluntary and IMO-sanctioned — conditions Iran has not accepted. Observers note the precedent extends beyond Hormuz: after Iran's spring toll attempt, Indonesia floated a comparable system for the Strait of Malacca, which handles 22% of global trade, signaling chokepoints can be monetized. A formal, collected fee by October 31 would resolve YES; continued negotiation or a non-compulsory framework would not. [Insurance Journal, Jul 8]
