Tanker attacks and toll threats choke Strait of Hormuz shipping
Will 60+ ships transit the Strait of Hormuz on any day by July 31?
Polymarket prices this 60+ at 1%. The reporting broadly agrees.
Iran's military fired missiles at commercial ships transiting the Strait of Hormuz this week, killing two mariners and injuring at least 14, while India summoned Tehran's senior diplomat in New Delhi to protest the deaths of an Indian seafarer. The attacks on UAE-associated tankers coincide with a US presidential proposal to impose fees on ships passing through the strait, which Reuters notes are already creating de facto tolls. The question being tracked is whether IMF Portwatch will finalize a daily transit count of 30 or more ships through the strait on any single day before July 31. Traders put the probability at 1%, a figure that has slipped +0.2 pts over the past week as disruptions persist.
Background
The Strait of Hormuz handles roughly a fifth of global oil consumption, making any disruption there a flashpoint for energy markets. Iran has periodically harassed commercial shipping in the chokepoint, but the recent missile strikes mark an escalation. The US fee proposal adds a second layer of pressure on shippers. IMF Portwatch tracks daily arrivals of container, dry bulk, ro-ro, general cargo, and tanker ships; a count of 30-plus transits on any finalized day before the July 31 cutoff would resolve the question affirmatively. Related propositions on whether traffic returns to normal by mid-July, end-of-July, or end-of-August all lean toward no.
The precedent
- The Strait of Hormuz has experienced periodic shipping disruptions linked to Iranian actions, including a 2019 tanker attack campaign and the 2024 seizure of the Stena Impero.
- IMF Portwatch is a platform that tracks global shipping arrivals using AIS data and is maintained by the International Monetary Fund.

How outlets frame it
- Reuters: Frames the toll issue as already effectively happening through de facto charges rather than formal policy, suggesting the shipping-fee proposal is less a new threat than a recognition of existing friction.
What to watch
The next IMF Portwatch data releases will show whether daily arrivals rebound above 30 or stay suppressed amid the security crisis. Any further Iranian attacks or US enforcement actions on shipping fees would deepen the disruption. The resolution window closes July 31.
