France's economy ground to a halt in the first three months of 2026, official data released Thursday show, as the energy shock triggered by the Iran war began to squeeze households and businesses across Europe's second-largest economy.
Gross domestic product was flat quarter-on-quarter, according to a preliminary estimate from the national statistics institute INSEE. That marks a clear deceleration from the 0.2% expansion recorded in the final quarter of 2025 and fell short of analyst expectations. The figures underscore how quickly the conflict that erupted on 28 February is feeding through to the real economy.
The data reveal broad-based weakness. Consumer spending edged down 0.1% over the quarter, while overall investment dropped 0.4%, dragged by declines in construction and manufactured goods. Exports slumped 3.8%, subtracting 0.7 percentage points from growth via net trade. Only a build-up in inventories, which added 0.8 points, prevented an outright contraction.
Inflation Accelerates as Growth Stalls
Inflation quickened to 2.2% in April, the highest reading since mid-2024 and above market forecasts, pointing to price pressures running in the opposite direction to growth. The rise is directly linked to the surge in global energy costs following the US-Israeli strikes on Iranian military infrastructure and the effective blockade of the Strait of Hormuz, through which roughly 20% of the world's seaborne crude oil passes.
Those price increases are now feeding into household energy bills, industrial costs and transport, compressing purchasing power at a time when French consumers were already cautious. The impact is also visible in neighbouring economies: France and Italy have both trimmed their growth outlooks, while Germany halved its 2026 forecast to 0.5%.
The European Commission and the European Central Bank are watching the situation closely. As energy costs drive inflation higher in Germany and Spain, the ECB faces a difficult balancing act between containing price pressures and supporting a slowing economy.
Chatham House analysts warn that the eurozone economy could contract in the second quarter and then flatline over the second half of the year if the conflict persists for several months. The EU has already relaxed state aid rules to shield businesses from the crisis, but the effectiveness of those measures remains uncertain.
For France, the outlook is particularly concerning given the country's heavy reliance on nuclear power for electricity generation. While that insulates it somewhat from oil price spikes, the broader economic linkages—especially through trade and industrial supply chains—are proving vulnerable. The slump in exports, which fell by nearly 4% in a single quarter, reflects weaker demand from trading partners also grappling with higher energy costs.
The data capture only the opening weeks of the conflict, meaning the full impact is likely yet to be felt. With no end to hostilities in sight, French policymakers are bracing for a prolonged period of sluggish growth and elevated inflation—a combination that risks reviving the stagflation fears that haunted Europe during the 2022 energy crisis.
