Energy Security Index — September 2026: 46.5

The Energy Security Index started September at its lowest point of 31 before rising throughout the month. Tensions were pushed up by news of Russia launching its largest attack on Ukraine's energy infrastructure since spring and oil prices surging after Trump rejected Iran's plan to reopen the Strait of Hormuz. Concerns over an oil shock potentially driving fuel prices higher further raised market anxiety, alongside driver strikes in the Philippines. Tensions calmed slightly when US tariffs against Russian oil buyers passed, though India warned these tariffs could impact ties. Overall, the index reached a peak of 61 on September 24 and finished the month with an average score of 46.5.
