Shipping Stress Index — August 2026: 56.9
31 days · ModerateThe Shipping Stress Index averaged 56.9 in August 2026, driven by several regional conflicts. Tension pushed higher due to new tanker strikes in the Strait of Hormuz, U.S. strikes to prevent mine threats, and a drone attack on Egypt. Pressures were also heightened as Trump threatened more strikes on Iran, warned he would bomb Oman if it got in the way, and refused to extend an Iran ceasefire. The index hit a peak of 72 on August 7, but it calmed significantly on August 22 when it dropped by 41 points to reach its lowest level of 27. The month ended on a quieter note as the index fell by another 5 points on August 30 while Trump weighed limited strikes against Iran.
