The United States has not yet implemented a renewed naval blockade in the Strait of Hormuz, as shipowners require a 24-hour notice period before such actions can take place, Axios reported, quoting a U.S. official. This development follows previous reports of a blockade in April 2026, which was lifted in June under a provisional ceasefire agreement. Despite these reports, no official announcement of a new blockade has been made, and the current ceasefire status remains in place. The situation has led to uncertainty in prediction markets regarding the volume of ship transits in the Strait of Hormuz.

Key Takeaways

• The report suggests that the US naval blockade has not been initiated due to the lack of a 24-hour notice to shipowners.
• Market pricing implies uncertainty about ship transits in the Strait of Hormuz, with some scenarios indicating a potential decrease in the probability of high ship transit numbers.
• The current ceasefire agreement between the US and Iran appears inconsistent with the implementation of a new blockade, adding to market uncertainty.

What to Watch

Watch for any official announcements from the US government or military that could confirm or deny the implementation of a new blockade. Developments from the Iranian Revolutionary Guard Corps (IRGC) or shipping companies such as Maersk and CMA CGM could provide additional context. Any change in the ceasefire status or discovery of sea mines could further impact market expectations regarding ship transits through the Strait of Hormuz.
