Why are global oil investments expected to decline for the third consecutive year, according to the IEA?

Global oil investments are expected to fall for the third year in a row due to the supply shock from the Middle East conflict—specifically the US-Israeli war on Iran—which effectively closed the Strait of Hormuz, a critical waterway through which a fifth of the world’s seaborne crude was shipped; this disruption has caused price spikes and supply shortages, prompting companies and countries to shift investment priorities toward new trade routes and alternative energy sources instead of oil projects.

What does the IEA identify as the largest energy security crisis in history, and what strategic shifts is it driving?

The IEA identifies the current turmoil in oil markets—triggered by the closure of the Strait of Hormuz—as 'the largest energy security crisis the world has ever faced', and states that it is reshaping global investment strategies by intensifying efforts among both producer and consumer countries to diversify trade routes and energy sources, with overall energy investments in 2026 rising to $3.4 trillion but flowing predominantly into power grids, storage, low-emissions fuels, nuclear, renewables, and electrification rather than oil.
