Assessment

High confidence: 3/4 signals corroborated across 4 independent sources

The International Maritime Organization (IMO) has confirmed 80 attacks on international shipping in the Strait of Hormuz since the Middle East conflict began, resulting in at least 22 seafarer deaths since February 28. This represents a formal escalation of concern by the IMO, which has urged member states to halt attacks on merchant vessels. The underlying conflict dynamics remain unchanged, but the direct human cost and frequency of attacks have increased.

Why it matters: The persistent threat to this critical energy chokepoint has direct implications for global shipping, energy transit, and supply chain stability.
