Jet fuel has become a clear test case: the Strait of Hormuz closure disrupted refined-product flows as well as crude and gas, exposing sectors that cannot easily electrify.
More than 40% of Europe’s jet fuel imports came from the Persian Gulf last year, and sustainable aviation fuel now costs about 1.5 to 2 times conventional fuel, down from 3 to 5 times.
Airlines and refiners still are not rushing in, because higher fuel costs are squeezing profits and price volatility is deterring the long-term purchase contracts and new projects needed to expand SAF supply.
Governments are better placed to act, treating the premium for synthetic or sustainable fuels as an energy-security cost; the EU has hardened its SAF mandate, while the U.S. debate remains stalled.
Fuels still account for nearly 80% of final energy consumption, making the Hormuz crisis a broader warning that the energy transition needs faster innovation in low-carbon molecules, not just electrification.

The 2026 Strait of Hormuz Crisis: Global Energy Shock, Maritime Paralysis, and the Collapse of Middle East Diplomacy
Overview
The July 2026 crisis began when Israeli airstrikes in Lebanon led the IRGC to re-close the Strait of Hormuz, collapsing the peace agreement and causing maritime traffic to plummet by 90%. This triggered a global oil supply shock, with prices soaring and the IEA releasing emergency reserves. The disruption also halted fertilizer exports, threatening agriculture in Asia, Africa, and Latin America, while inflation and currency crises hit developing nations hard. As insurers withdrew coverage, shipping lines rerouted vessels around Africa, adding weeks and millions in costs. Meanwhile, military escalation—including U.S. airstrikes and Houthi attacks—deepened the crisis, leaving tankers stranded and creating severe environmental risks.
