President Donald Trump has declared a full blockade on Iranian shipping, excluding vessels not linked to Iran. This move represents a significant escalation in the ongoing conflict between the United States and Iran over control of the Strait of Hormuz. The blockade, initially put in place in April 2026 but temporarily lifted in June, has been reinstated following the collapse of a ceasefire agreement earlier in July. The blockade aims to target Iran’s economic capabilities without fully closing the vital Strait, though shipping traffic remains severely limited, impacting global trade.
Key Takeaways
The blockade announcement appears to reduce the likelihood of the Strait of Hormuz traffic returning to normal by August 31, with market pricing suggesting a 12.5% probability of normalization.
Markets indicate a significant decrease in confidence for normal traffic by July 31, with probabilities dropping to 2.1% following the announcement.
The U.S. strategy of targeted economic pressure seems consistent with market expectations of long-term disruptions in the Strait of Hormuz.
