IEA Calls Hormuz Closure the Biggest Energy Security Threat in History as 60 Nations Scramble

IEA Calls Hormuz Closure the Biggest Energy Security Threat in History as 60 Nations Scramble With 13 million barrels per day of oil lost and 60 countries enacting emergency measures, the crisis is accelerating both coal reversion and renewable investment simultaneously. The world has lost 13 million barrels per day of oil supply, IEA executive director Fatih Birol told CNBC, describing the Hormuz disruption as the biggest energy security threat in history. The 32-member IEA agreed in March to release 400 million barrels from emergency stockpiles to mitigate the impact. Europe's jet fuel supply has been particularly hard hit — roughly 75 percent of the continent's jet fuel came from Middle Eastern refineries, a flow that Birol said has now dropped to essentially zero.² At least 60 countries have taken emergency measures in response, according to Carbon Brief analysis. Nearly 200 policies have been announced to save fuel, support consumers and boost domestic energy production. A fifth of the world's oil and LNG normally transits the region, with 90 percent of those supplies destined for Asia. The policy response spans the full spectrum from coal reversion to accelerated renewable deployment.⁴ Coal is getting the most immediate boost. Countries across Asia and Europe are returning to coal-fired generation after the conflict severely disrupted global LNG supplies. Birol himself acknowledged the trend, saying he expected coal use to push back up in some big Asian countries. The fashionable proclamation is that coal is the war's big winner.^7,2 China's data confirm the pattern. Total power generation rose an estimated 6.6 percent year-over-year in April, but weak wind conditions, subdued solar performance and extended nuclear refuelling outages pushed coal power up for a fourth consecutive month. Thermal power commissioning in the first quarter surged more than 160 percent year-over-year, reaching a record high. China boosted coal and gas generation by 3.1 percent in April as wind and nuclear output fell.^1,6 The Hormuz disruption hit China's imports directly. Crude oil and natural gas imports fell roughly 20 percent and 13 percent year-over-year respectively in April as shipping through the strait seized up. Solar cell production dropped 25.6 percent on weaker domestic installations. But battery output rose 55.6 percent, supported by energy storage demand and exports. The numbers capture an economy pivoting simultaneously toward more coal and more storage — contradictory moves driven by the same supply crisis.¹ The Economist argued that the real winner is renewables, not coal. Two new reports make the case that domestic energy sources — wind, solar, nuclear — gain strategic appeal precisely because they eliminate chokepoint risk. The IEA itself says nations are increasingly investing in renewables, nuclear and electricity infrastructure to strengthen resilience. The logic is straightforward: every megawatt-hour generated domestically is a megawatt-hour that does not transit Hormuz.⁵ The Oxford Institute for Energy Studies framed the question differently. The issue is not whether energy transition risks exist but whether European leaders engage with them seriously enough, and soon enough, to shape the terms on which the transition lands. The dependencies that Hormuz has exposed — on Middle Eastern refining, on Qatari LNG, on a single maritime chokepoint — were known risks that were priced as tail events until they were not.⁸ Asia's response will determine whether the crisis accelerates or delays the clean energy transition. Analysts say the pivot to coal carries serious environmental and public health costs in the near term. But the same analysts argue the crisis could ultimately accelerate the shift toward renewables by demonstrating the security premium of domestic generation. Both views can be correct simultaneously — coal fills the gap now while renewables get funded faster for the medium term.³ China's solar capacity additions fell 31 percent year-over-year in the first quarter, partly reflecting a high base from the prior year. Wind additions rose 8 percent. The mixed signals suggest that clean energy deployment is not collapsing under the crisis but is growing unevenly, with wind outperforming solar on installation pace while coal handles the acute supply shortfall.¹ The unresolved question is whether the 400 million barrels of IEA strategic releases buy enough time. If Hormuz reopens within the ceasefire window, the emergency stocks can be replenished and the crisis becomes a temporary disruption that accelerated investment in domestic energy. If the strait stays contested, the stockpile drawdown becomes a countdown. The next IEA coordinated release decision — and whether non-IEA members like China and India participate — is the signal that will tell traders whether governments believe this crisis is weeks or months from resolution.
