Iran charges Hormuz fees by 2026?

Platform comparison

Market context

Iran has moved from talk of a toll to a narrower “service fee” model for ships using the Strait of Hormuz, which is why the market is still pricing this at **0% YES** despite repeated headlines. Reuters reported in early August that Tehran wants 5% to 7% of cargo value under a proposed passage deal, while Oman and Washington are pushing lower or zero fees; earlier Reuters coverage also described Iranian officials discussing voluntary fees, and other outlets have reported Iran saying it is charging for navigational services rather than imposing tolls.[6][1][8][9]

The key historical comparison is that this contract requires an **official, general, mandatory** charge, not ad hoc demands or a temporary wartime surcharge. Bloomberg reported in March that some ships were being asked for irregular transit payments, but the market definition excludes isolated charges; the Reuters piece from April also noted that UNCLOS does not permit fees solely for passage, which helps explain why traders treat a formal nationwide toll as a high bar.[5][4] On that reading, the current zero-implied market is consistent with the distinction between informal collection and a binding policy.

The main catalysts are any formal joint Iran–Oman announcement, a published fee schedule, or enforcement language showing that commercial vessels must pay to pass. Reuters said on 6 August that the proposed Hormuz passage deal was not yet feasible and that the parties remained divided on fee levels, with shipping-industry sources sceptical of implementation.[6] Until there is a clearly announced and generally applicable rule, the odds are likely to stay well below analyst-style “maybe” territory, and the gap between the prediction market’s 0% and the sporadic news-driven chatter remains the central tradeoff on this contract.
