Energy Security Index — April 2026: 31.6

The Energy Security Index averaged 31.6 in April 2026, touching a low of 23 on April 14 before climbing to a peak of 46 on April 25. Tensions spiked early as crude oil prices hit records due to supply disruptions and jumpy markets, while fears grew over a U.S. blockade of Iran and potential escalations in the Strait of Hormuz. Later in the month, pressure eased temporarily when Iran declared the Strait of Hormuz open, causing U.S. oil prices to plunge below $84. However, uncertainty returned toward the end of April as reports emerged that President Trump was dissatisfied with Iran's proposal to open the strait, leaving oil hovering near $100.

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