Supply Chain Risk Index — July 2026: 47.6

The Supply Chain Risk Index started July at its lowest point of 40 before rising over the course of the month. Tension was pushed up by ocean shippers abandoning traditional practices due to tariffs and the Iran war, sending the index to a peak of 55 on July 19. Other major headlines involved a fertilizer shortage from the Iran war, diesel export bans from Russia, and cyber attacks linked to North Korea. Meanwhile, US logistics costs dropping to 7.8% of GDP helped calm things down toward the end. Overall, the month ended with an average risk score of 47.6.

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