Middle East war reshaping global energy strategies, IEA warns

The Middle East war is pushing countries to open new supply routes and turn to domestic resources to manage the world's biggest energy crisis, the International Energy Agency said Thursday.

The warning came in the IEA's World Energy Investment report, published by the energy agency of the OECD.

How is the Middle East war reshaping energy security strategies?

Countries are responding to the Middle East war by diversifying trade routes, advancing new pipeline infrastructure and shifting toward domestically available energy sources.

The IEA describes this as the largest energy security crisis the world has ever faced, drawing comparisons to the oil shocks of the 1970s that fundamentally changed how nations plan and invest in energy.

Where is global energy investment heading in 2026?

The IEA estimates global energy investment will reach $3.4 trillion in 2026, slightly above the previous year. Around $2.2 trillion of that total is earmarked for power grids, storage, low-emission fuels, nuclear, renewables, energy efficiency and electrification. The remaining $1.2 trillion is expected to go toward oil, natural gas and coal.

Despite rising crude prices, oil investment is projected to fall below $500 billion in 2026, marking the third consecutive annual decline. Uncertainty over price durability, long project lead times, supply constraints and a tightening offshore rigs market are all limiting short-term investment outside the Middle East.

Why is natural gas investment rising to a decade high?

Investment in natural gas is projected to reach $330 billion in 2026, the highest level in 10 years. A wave of new LNG export projects, particularly in the United States and Qatar, is driving that growth.

The IEA identified gas infrastructure as a key hedge for countries seeking supply security amid ongoing conflict-driven market disruption.

How are oil-importing countries responding to the energy crisis?

Oil-importing nations are turning to domestically available energy sources, including renewables, nuclear and coal.

Renewables investment is forecast to reach around $665 billion in 2026, with solar alone accounting for $365 billion of that figure. Nuclear investment is set to exceed $80 billion annually.

Coal investment is expected to reach $180 billion in 2026, the highest level in a decade. China will account for nearly 70% of global coal supply spending, and some Asian countries are considering extending the operational life of existing coal-fired plants to bolster energy security.

What is the IEA projecting for electricity infrastructure spending?

Investment in electricity supply and infrastructure is expected to reach nearly $1.6 trillion in 2026. That includes around $550 billion for power grids and more than $100 billion for battery storage.

IEA executive director Fatih Birol said the crisis will reshape investment strategies globally, in the same way the 1970s oil shocks transformed the energy landscape for decades.
