Iran charges Hormuz fees by 2026?

Platform comparison

Market context

Iran and Oman are advancing a joint proposal to impose mandatory administrative fees on commercial vessels navigating the Strait of Hormuz, a move that directly contradicts current US objections and existing international law which forbids tolls on international waterways[1][2]. This real-world development frames the market’s 2% implied probability: while the diplomatic push is tangible, the US has explicitly stated it will oppose any monetisation of the strait, regardless of whether it is labelled a fee, toll, or donation[2]. Historically, similar service-fee models exist in the Straits of Malacca and Singapore, where voluntary contributions ensure safe navigation, yet Iran insists its charges will be obligatory, creating a critical divergence from established precedents[1][7].

Traders should monitor the upcoming discussions between Iran and Oman scheduled to begin next week, as Tehran’s deputy foreign minister has warned that if no agreement is reached, Iran will impose its own unilateral fees[2][3]. The settlement hinges on whether the US and other Persian Gulf states accept the joint administration plan, which includes fee collection through the International Maritime Organization for environmental risk assessment and rescue efforts[1]. Recent reports confirm that US negotiators have reviewed the Omani proposal but hold significant concerns, suggesting the path to implementation remains fraught with diplomatic resistance[2]. The on-chain mechanics on Polymarket, utilising USDC on the Polygon network and conditional tokens, will resolve based on an official Iranian announcement of mandatory collection, a threshold that remains unmet despite the active diplomatic negotiations[1].
