Iran increased its commodity exports through the Strait of Hormuz in March while US-Iran tensions continued. The market for Strait of Hormuz Ship Transit April, which tracks whether 10 ships will transit the strait on any day between April 8 and April 12, is expected to see odds rise by 15%.
Market reaction
The transit market is drawing more interest. Iran has maintained selective control over the Strait, allowing compliant ships through, which raises the probability of meeting the 10-ship daily threshold. With Iranian exports up while regional rivals face constraints, traders are pricing in higher ship movement volumes.
The related Trump’s Hormuz Blockade Announcement market is unchanged at 82% YES for a blockade lift by May 31. No new US policy shifts have materialized, so traders read the increased Iranian exports as a regional maneuver rather than a direct challenge to US plans.
Why it matters
Iran’s operational control over Strait traffic persists even with US naval forces in the area. This gives Tehran asymmetric leverage over one of the world’s most important shipping chokepoints. Traders betting YES on the transit threshold are wagering that Iran can continue dictating which ships pass through. A YES share at 22¢ pays $1 if 10 ships transit the Strait during the specified period, a potential 4.5x return.
What to watch
Monitor announcements from IMF Portwatch and any shifts in IRGC policies on transit restrictions. These are the most direct signals for whether ship movements will increase over the coming days.
