Iran publishes draft plan to toll Strait of Hormuz, targeting US and Israeli ships
Iran charges Hormuz fees by...?
Polymarket prices this December 31 at 43%. The market is more confident than the current reporting.
Iran has published a draft plan to impose mandatory tolls on commercial vessels transiting the Strait of Hormuz and ban U.S. and Israeli ships outright, sending oil prices sharply higher. The proposal, reported across outlets from CGTN to CNBC over the past two weeks, represents Tehran's most concrete step yet toward monetizing passage through the chokepoint that carries roughly a fifth of global oil supply. Fortune, however, dismisses the prospect of a $20 billion annual revenue haul as a "pipe dream," noting the enormous logistical and enforcement barriers. The specific question at issue is whether Iran officially announces and begins collecting such fees by December 31 — a deadline the market's 43% price at roughly a coin flip, even as reporting emphasizes that no formal collection mechanism yet exists.
Background
The Strait of Hormuz, linking the Persian Gulf to the Gulf of Oman, is the world's most critical oil transit chokepoint. Iran has long threatened to close or restrict the waterway in response to Western pressure but has never implemented a formal toll regime. The New York Times reported this month on an emerging Iran-Oman deal that could formalize joint management of the strait, potentially cementing Tehran's influence. The specific proposition being tracked is whether Iran officially announces and begins collecting mandatory fees from commercial vessels for passage through the strait by the stated December 31 deadline, with enforcement against noncompliant vessels as a qualifying condition.
The precedent
- Iran has periodically threatened to close the Strait of Hormuz during times of tension with the West, including during the Iran-Iraq War in the 1980s and in 2012 and 2019, but has never implemented a formal toll or fee regime on commercial traffic.
- The Strait of Hormuz carries approximately 20% of the world's daily oil supply, making it the most critical maritime oil transit chokepoint globally.

What the coverage agrees on
- Iran has published a draft plan to charge tolls on vessels transiting the Strait of Hormuz
- The plan would ban U.S. and Israeli ships from the strait
- Oil prices rose following the announcement
- No formal fee-collection mechanism has been implemented yet
Where sources diverge
- Whether Iran can realistically collect the tolls: Fortune calls the projected $20B annual revenue a 'pipe dream,' while other outlets report the plan without assessing its feasibility
What to watch
The resolution date is December 31, with roughly 17 days remaining in the tracking window. Watch for whether Iran's draft plan advances from proposal to an officially announced, operational fee-collection policy — or stalls amid logistical hurdles and diplomatic pushback. A parallel question, the Iran-Oman Hormuz management agreement by September 30, could signal whether Tehran is consolidating control through negotiation rather than unilateral imposition.

Resolves on: 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…
