Who wins and loses in the global energy shock

The economic fallout from the Iran war is exposing a widening divide between countries able to absorb energy disruption and those still deeply vulnerable to it. While oil shocks have historically rewarded exporters and punished importers, the current crisis is producing a more uneven hierarchy defined by infrastructure, diversification, and exposure to fossil fuel volatility.

Economies with larger renewable sectors, electrified transport systems, strategic reserves, and more flexible supply chains are proving better positioned to manage the disruption, while heavily import-dependent states face rising inflation, mounting subsidy costs, and growing pressure on trade balances. In its April 2026 Commodity Markets Outlook, the World Bank warned that energy markets were experiencing their largest geopolitical upheaval since Russia’s invasion of Ukraine. The International Energy Agency meanwhile described the Iran war as “the largest supply disruption in the history of the global oil market,” reporting that combined crude output from Kuwait, Iraq, Saudi Arabia, and the United Arab Emirates fell by at least 10 million barrels per day during the first two weeks of March alone, temporarily removing roughly 20% of global crude supply and a similar share of liquefied natural gas (LNG) from the market.

As the shock spreads through global markets, the countries emerging strongest are often not the largest oil producers, but the economies that spent years reducing their dependence on imported fossil fuels.

The cost of import dependence

The countries hit hardest by the Iran war were not necessarily those geographically closest to the fighting. In many cases, the greatest exposure fell on economies whose industrial systems still rely heavily on imported fossil fuels and maritime energy flows.

According to the Middle East Council on Global Affairs, roughly 84% of crude oil and 83% of LNG passing through the Strait of Hormuz is destined for Asian buyers, with nearly 70% of that oil bound for China, India, Japan, and South Korea alone. The concentration leaves many of Asia’s largest economies acutely exposed to disruptions in Gulf shipping routes.

The dependence is particularly severe in Northeast Asia. A 2026 briefing from Zero Carbon Analytics found that Japan imported 94.2% of its crude oil from the Middle East in February 2026, the highest dependency rate among advanced economies. The report also identified Japan as the Asian economy most exposed to supply disruptions in the Strait of Hormuz, followed by South Korea and India. South Korea routes more than 95% of its Middle Eastern crude through Hormuz, leaving both economies especially vulnerable to shipping disruptions and price spikes.

The pressure quickly spread into inflation and manufacturing costs. A recent analysis published by the Centre for Economic Policy Research estimated that sustained oil price increases linked to the conflict could raise U.S. inflation by as much as 0.6 percentage points over the following year, even without a full closure of Hormuz. The impact on import-dependent Asian economies would likely be considerably larger because energy costs feed directly into electricity generation, shipping, fertilizer production, and industrial manufacturing.

The exposure is especially acute in countries where electricity systems remain tied to imported LNG and oil. In South Asia and parts of Southeast Asia, governments are already confronting higher subsidy costs as fuel import bills rise. The World Bank noted in its April 2026 outlook that energy-importing developing economies are facing growing financial strain from rising fuel costs, especially in countries where currencies have already weakened against the dollar.

China’s complicated advantage

At first glance, China appears highly exposed to the conflict. Roughly half of its crude oil imports originate from the Middle East, according to analysis from the Center for Strategic and International Studies. Beijing also remains heavily dependent on maritime trade routes vulnerable to disruption in the Gulf and Indian Ocean.

Yet China entered the crisis with several advantages that many other major economies lack.

Research from the Center on Global Energy Policy at Columbia University notes that China has spent years diversifying both suppliers and transport routes. Russian pipeline imports, long-term LNG contracts, expanded strategic petroleum reserves, and major investments in domestic renewables have reduced the country’s vulnerability to single-point disruptions. China also dominates global clean energy manufacturing, producing the majority of the world’s solar panels, battery cells, and electric vehicle supply chain components.

China also entered the crisis with unusually large emergency reserves. According to Columbia’s analysis, Beijing held between 1.3 and 1.4 billion barrels in strategic petroleum reserves heading into 2026, equivalent to roughly four months of import demand and more than three times the size of the U.S. Strategic Petroleum Reserve.

Its supplier diversification has also reduced reliance on vulnerable maritime chokepoints. The Columbia report noted that overland pipelines from Russia and Central Asia accounted for roughly 38% of Chinese oil imports in 2025, providing Beijing with partial insulation from disruptions in Gulf shipping lanes.

That matters because electrification increasingly functions as a form of geopolitical insulation. Economies with larger electric vehicle fleets, high-speed rail networks, renewable-heavy power grids, and domestic battery industries are less exposed to oil price volatility than systems dependent on gasoline transport and imported fuel generation.

The CSIS analysis argues that while the conflict creates near-term economic pressure for Beijing, it may simultaneously reinforce China’s long-term industrial strategy. Rising fossil fuel insecurity strengthens the strategic rationale behind investments Beijing was already making in electrification, renewable deployment, and supply chain control.

At the same time, China still faces substantial risks. Roughly one-third of global seaborne oil trade passes through the Indian Ocean and adjacent chokepoints vulnerable to escalation. Insurance costs for tankers operating near the Gulf have already risen sharply, increasing transport costs across Asian supply chains.

Europe’s energy buffer

Europe entered the Iran conflict in a far stronger position than it occupied during the 2022 energy crisis triggered by Russia’s invasion of Ukraine. Gas storage levels are higher, LNG infrastructure has expanded, and renewable deployment has accelerated across much of the continent.

Still, analysts at Bruegel, a Brussels-based economic policy think tank, warn that Europe remains exposed to volatility in global LNG markets. Unlike the Russian gas shock, which centered primarily on pipeline infrastructure, the Iran conflict threatens maritime shipping routes that affect both oil and LNG simultaneously.

The European Union imported record levels of LNG following the collapse of Russian pipeline flows, increasing dependence on maritime energy transport from the United States, Qatar, and other exporters. Any sustained disruption in Gulf shipping therefore places upward pressure on both gas and electricity prices across Europe.

Yet the crisis also highlighted where Europe has reduced vulnerability. Renewable electricity generation now accounts for a much larger share of the European power mix than during previous energy shocks. According to the International Energy Agency, additions in solar and wind capacity across Europe over the last several years have helped reduce gas demand in electricity generation, limiting some of the inflationary pressure associated with fossil fuel spikes.

Countries with larger renewable capacity and more interconnected electricity systems have generally absorbed the shock more effectively than those still reliant on imported fuels for baseload generation.

Infrastructure as energy security

The Iran war reinforced a broader shift already underway in the global economy. Energy security is no longer defined solely by access to oil reserves. Increasingly, it depends on the resilience and flexibility of infrastructure itself.

The countries best positioned to absorb the disruption are not necessarily the largest hydrocarbon exporters, but economies with diversified grids, strategic reserves, renewable capacity, electrified transport systems, and multiple trade corridors. The geopolitical consequences extend well beyond the Middle East. States less dependent on volatile maritime fossil fuel flows are gaining greater insulation from external shocks, while countries still reliant on imported oil and LNG remain exposed not only to price spikes, but to the political leverage tied to concentrated energy infrastructure.

The result is an increasingly uneven global divide in which resilience is becoming as strategically important as access to fuel itself.
