US maintains legal blockade of Strait of Hormuz, reducing war declaration likelihood

## Market Snapshot

The market for Trump announcing the lifting of the US blockade of the Strait of Hormuz by May 31, 2026, currently indicates a 29.5% YES probability, down from 40% one day ago. The market for a US declaration of war on Iran by December 31, 2026, shows a 7.5% YES probability, slightly up from 6% a day earlier.

## Key Takeaways

– The statement by Acting AG Todd Blanche that the blockade is legal suggests a continuation of the current US stance. – Markets appear to interpret the blockade as a de-escalatory measure, decreasing the likelihood of a US war declaration. – The confirmation of legality may indicate a reduced probability of the blockade being lifted imminently.

## Article Body

In response to inquiries about the United States’ stance towards Iran, Acting Attorney General Todd Blanche clarified that the active naval blockade is not an act of war but a legal enforcement measure. The blockade, initiated on April 13, 2026, following failed peace negotiations, aims to restrict Iranian oil exports while maintaining free passage for other nations. Although the blockade imposes significant economic pressure on Iran, US officials, including Blanche, assert its legality despite criticisms from international law experts. The ongoing enforcement reflects high tensions without an official war declaration, aligning with US strategies to pressure Iran economically.

## Market Interpretation

The clarification by Acting AG Blanche that the blockade is not a declaration of war and is legally upheld appears to be supportive of a NO outcome in the market predicting a war declaration by the US. The impact on the market is moderate, as the confirmation reduces the likelihood of an imminent escalation to declared warfare. The odds for a blockade lift announcement before May 31, 2026, have decreased, consistent with the US’s firm stance on maintaining the blockade.

## What to Watch

Observers should monitor any statements from key US and Iranian officials that might indicate shifts in diplomatic or military strategies. Developments in potential diplomatic talks or further economic sanctions could impact market expectations. Additionally, any unexpected military actions or changes in international support for the blockade could influence the likelihood of the US altering its current course.
