Shipping Stress Index — June 2026: 47.3

The Shipping Stress Index averaged 47.3 in June 2026, reaching its highest level of 55 on June 2. Tension was driven up early in the month by a Hormuz strike that killed three seafarers and a drone attack on a cargo ship that prompted U.S. strikes against Iran. Things calmed down as an LNG tanker headed toward Hormuz under a deal that raised hopes of reopening, leading to a rebound in shipping traffic one week after a U.S.-Iran agreement. However, confidence remained fragile, and the index hit its lowest point of 40 on June 24 after Iran struck another vessel, pausing UN ship evacuation efforts.

Scores in this month were computed by the first-generation engine (v1).
