The conflict involving Iran has become one of the most significant economic risks facing Europe in 2026, reigniting concerns that the eurozone could experience another period of elevated inflation just as policymakers believed price pressures were finally coming under control.
While the war’s direct effects are concentrated in the Middle East, its economic consequences are being felt across Europe through higher energy costs, disrupted supply chains, and growing uncertainty among businesses and consumers. At the center of these concerns is energy.
Europe remains heavily dependent on imported oil and liquefied natural gas, much of which travels through the strategically important Strait of Hormuz. Any threat to this shipping route immediately raises fears of supply shortages and sends commodity prices higher. Recent reports show oil prices approaching $100 per barrel as geopolitical tensions intensified, while natural gas prices have also surged amid concerns about future deliveries.
The impact on inflation is already becoming visible. Inflation across the eurozone has remained above the target level set by the European Central Bank, with rising fuel and transportation costs beginning to filter through the broader economy.

Economists warn that energy-driven price increases rarely remain confined to gasoline and electricity bills. Instead, they gradually affect manufacturing, logistics, food production, and consumer goods, creating widespread inflationary pressure. The challenge for Europe is that inflation is returning at a time when economic growth remains fragile. Several indicators suggest that business activity across the eurozone has slowed as firms face rising input costs and weaker demand.
Manufacturing surveys show companies struggling with higher commodity prices and longer delivery times, while business confidence has deteriorated amid uncertainty surrounding the conflict. This combination of slowing growth and rising prices has revived fears of stagflation—a particularly difficult economic environment for policymakers. Officials at the ECB have openly acknowledged these risks.
ECB President Christine Lagarde has warned that the Iran conflict could have a material impact on inflation, particularly if disruptions to oil and gas supplies persist. Under more severe scenarios, ECB projections suggest inflation could climb substantially above current forecasts, forcing the central bank to consider tighter monetary policy even as growth weakens. European consumers are also beginning to feel the effects.
Higher fuel prices reduce household purchasing power, leaving families with less disposable income for other goods and services. Businesses face a similar challenge as rising energy bills squeeze profit margins and force difficult decisions regarding investment, hiring, and production. Surveys across the region indicate declining consumer confidence as households prepare for the possibility of sustained price increases.
Looking ahead, the duration of the conflict will likely determine the severity of the inflation threat. If energy markets stabilize and supply routes remain open, Europe may avoid the worst-case scenario.
However, a prolonged disruption could push inflation higher, weaken economic growth, and force the ECB into difficult policy choices. For a region still recovering from previous energy shocks and inflationary episodes, the Iran war has become a stark reminder of how geopolitical conflicts can rapidly reshape economic realities far beyond the battlefield.
