Iran charges Hormuz fees by July 31?
🗂 Part of event: Iran charges Hormuz fees by...? →💡 What the odds say
The market puts this at about a 4% chance — almost no chance.
No money — just record your call and see if you were right. Yes is at 4% right now.
Iran is actively signaling a Hormuz fee policy, but the market heavily discounts a formal, general announcement by July 31 due to enforcement challenges and diplomatic pushback.
📊 Base rate: Governments rarely implement broad transit fees on international straits within weeks of announcement; the Strait of Hormuz has seen no such general fee in decades.
What's driving it
- • Iran's envoy to China explicitly promised 'special' treatment for friendly nations (Al Jazeera, Jul 5), suggesting a tiered system that may delay a uniform fee.
- • Oman's diplomatic balancing act over the fees (CNBC, Jul 3) indicates regional opposition that could stall implementation.
- • Iran announced service fees despite Trump's warning (The Media Line, Jul 6), but the lack of a clear start date or enforcement mechanism keeps odds low.
The case for YES
- • Iran and Oman jointly proposed charging for services through the Strait (Institute for Energy Research, Jul 7), showing state-level coordination that could lead to a formal announcement.
- • Iran has publicly stated it plans to charge ships (Jerusalem Post, Jul 5), and the market's 13% Yes suggests some probability of a last-minute policy rollout.
- • The fee could be framed as a 'service charge' for navigation aids, making it easier to announce as a general policy before July 31.
The case for NO
- • The policy explicitly exempts friendly nations (Times of Israel, Jul 4), which contradicts the resolution's requirement for a fee applying generally to all commercial vessels or a defined subcategory.
- • Oman's reluctance (CNBC, Jul 3) creates a diplomatic 'blind spot' that could prevent a joint or unilateral announcement within the deadline.
- • No concrete implementation date or enforcement mechanism has been announced, and the market sees only 13% chance of a formal, general fee by month's end.
What to watch
- • Any official statement from Iran's Supreme Leader or Foreign Ministry specifying a start date and fee structure before July 31 would push odds toward Yes.
- • A joint Iran-Oman announcement of a service fee (expected after ongoing talks) would likely increase Yes probability.
- • US or allied naval exercises or sanctions threats in response to the fee announcements could deter Iran, lowering Yes odds.

How it resolves
Settled on-chain by UMA's optimistic oracle: once an outcome is clear, anyone can propose the result, which then enters a challenge window where it can be disputed with evidence before it finalizes.

Resolution criteria
This market resolves to “Yes” if the Iranian government officially announces and begins collecting fees, tolls, charges, tariffs, or similar payments from commercial vessels which are mandatory for passage through or access to the Strait of Hormuz between market creation and the specified date, 11:59 PM ET. Otherwise, this market resolves to “No.” A qualifying fee must be an announced policy which applies generally to all commercial vessels, or a defined subcategory of commercial vessels (e.g., vessels flagged to the US and its allies). Isolated demanded charges will not qualify. A fee is mandatory if, in practice, affected commercial vessels cannot transit or access the Strait of Hormuz without paying it, regardless of whether Iran characterizes the payment as voluntary or a fee for services. Fees described as tolls, maritime fees, service charges, environmental fees, security fees, insurance charges, etc. will qualify provided they are recognized as mandatory for passage through or access to the Strait of Hormuz by a consensus of credible reporting (e.g., a mandatory insurance fee charged by the Iranian Persian Gulf Strait Authority would qualify). Both of the following are required to occur prior to the specified date, 11:59 PM ET to satisfy this market’s resolution criteria: 1) An official announcement from the Iranian government that such a fee is being, or will be, implemented. 2) A consensus of credible reporting that collection of the fee has begun. Fees charged by Oman, the United Arab Emirates, shipping insurers, private companies, or other non-Iranian entities do not qualify unless charged jointly with Iran, or if Iran directly receives the fee or controls the charging entity. Normal port fees, customs duties, sanctions-related costs, or shipping surcharges do not alone qualify. The resolution sources will be official announcements from the government of Iran and consensus of credible reporting.
