Iran conflict and Hormuz closure trigger global energy shocks, EV sales surge
Airstrikes on Iran beginning in February led to a closure of the Strait of Hormuz, a chokepoint for roughly a quarter of global oil trade and a fifth of exported liquefied natural gas. The disruption, described by the International Energy Agency as the largest supply shock in oil-market history, triggered fuel price spikes, unrest including fuel protests in Syria and a blockade by French fishers, and a roughly doubling of electric-vehicle sales year-on-year in countries such as Australia, Brazil and India.

The episode adds to a string of shocks—including the Russia-Ukraine war, COVID-19 and the 2008 financial crisis—that researchers say have cumulatively undermined global energy security, according to analyst Dan Marks. The surge in EV adoption suggests consumers and governments may be accelerating shifts toward electrification and renewables as a hedge against future fossil-fuel disruptions, though this trend could also simply reflect short-term price pressure rather than a permanent shift.
- Strait of Hormuz closure disrupted roughly 25% of global oil trade and 20% of LNG exports.
- IEA called it the largest oil-market supply disruption on record, fueling price spikes and unrest.
- EV sales roughly doubled year-on-year in Australia, Brazil and India amid the turmoil.
