US military to board Iran-linked ships globally, expanding naval blockade

US military plans to board Iran-linked ships globally, expanding its naval blockade. Strait of Hormuz traffic normalizing by end of May is at 25% YES, down from 50% last week.

Market reaction

The Strait of Hormuz traffic market dropped from 50% to 25% on normalization by end of May, a halving in one week driven by increased military and economic pressure on Iran. The UK warship deployment market is at 6% YES, down from 12% a week ago, showing skepticism about imminent allied naval involvement.

Why it matters

The boarding plans signal a broader enforcement strategy against Iranian-linked vessels worldwide, not just in the Strait itself. This makes normalization of Strait traffic harder because commercial shipping faces direct interdiction risk. The UK warship market’s decline from 12% to 6% suggests traders don’t expect allied forces to join the US operation soon, which could mean Washington is acting largely unilaterally.

What to watch

The Strait of Hormuz traffic market had zero 24-hour trading volume, so the 25% odds reflect stale sentiment rather than active conviction. The warship deployment market has $8,344 in USDC traded, with a $478 cost to move the price 5 percentage points, meaning a single large order could shift odds meaningfully.

At 25¢, a YES share pays $1 if traffic normalizes by end of May, a 4x return. That bet requires believing in real diplomatic progress or military de-escalation within roughly 45 days. Watch for CENTCOM operational updates and any direct diplomatic signals between Ali Khamenei and Donald Trump.
