The US is preparing to board Iran-linked ships globally following an attack by Iranian gunboats on a tanker in the Strait of Hormuz. The Strait of Hormuz traffic market tracking whether traffic returns to normal by end of May now faces downward pressure, with odds expected to decrease by 15%.
Market reaction
The ships transit through the Strait of Hormuz market, which resolves on April 19, moved to 0.4% YES from 0%, as traders price in a lower likelihood of high transit numbers this week. The market has minimal actual USDC traded and remains sensitive to small orders, shown by a 2-point spike early this morning.
Why it matters
The largest single move in Hormuz transit odds was a 2-point spike at 4:25 AM, with just $12 needed to move the market 5 points. This is a thin order book where even minor trades cause noticeable shifts. With 43 days left until the May normalization date, the US actively preparing to board Iran-linked ships raises the probability of further maritime disruptions. At current odds, betting on fewer than 10 ships transiting by April 19 could pay out significantly if the situation worsens.
What to watch
CENTCOM’s next operational update and Iran’s naval movements are the two triggers. Any confirmation of US boardings or further Iranian military actions would move these markets.
