The European Commission warned on Thursday that the eurozone economy will experience a noticeable slowdown in 2026 following the outbreak of war in the Middle East, which has triggered the region’s second significant energy crisis in less than five years.
The extent of the damage will depend heavily on the duration of the conflict and its impact on global energy supplies.
“Before the end of February 2026, the EU economy was set to keep expanding at a moderate pace alongside a further decline in inflation, but the outlook has changed substantially since the outbreak of the conflict,” the Commission said in its Spring 2026 Economic Forecast.
The Commission now expects euro zone GDP growth to slow to 0.9% in 2026, down from a previous projection of 1.2% and well below the 1.3% recorded in 2025. Growth is then forecast to edge up only modestly to 1.2% in 2027.
Inflation forecasts were revised significantly higher, rising to 3.0% in 2026 (from 1.9%) and 2.3% in 2027 (from 2.0%). These upward revisions reflect surging oil prices above $100 per barrel and severe disruptions to shipping through the Strait of Hormuz, which have created a substantial supply-side shock.
The Commission noted that domestic consumption is still expected to remain the primary driver of growth, but both consumer and business sentiment have deteriorated rapidly. Investment is likely to be constrained by tighter financing conditions, lower profits, and heightened uncertainty, while weaker global demand is weighing on exports.
ECB Likely to Hike Rates in June for Credibility
The worsened inflation outlook strengthens the case for the European Central Bank to raise interest rates at its June 11 policy meeting. Markets are pricing in one or two additional hikes over the next 12 months, which would lift the deposit rate from the current 2% toward 2.50–2.75%.
ECB policymaker Olli Rehn, Governor of the Bank of Finland, acknowledged the difficult balancing act.
“The euro area was sliding towards the ECB’s ‘adverse scenario’ of slower growth and higher inflation, which may force it to raise rates for the sake of credibility,” he said.
However, Rehn struck a relatively measured tone, noting that longer-term inflation expectations remain well anchored around the ECB’s 2% target. He pointed out that gas prices have not risen as sharply as oil, wage growth continues to moderate, and there are limited signs of second-round effects so far.
“From the standpoint of medium-term orientation, the critical thing is whether we see evident signs of second-round effects, and/or de-anchoring of inflation expectations… we see some vibration in the short-term inflation expectations, but no significant deviation in medium- to long-term inflation expectations,” he said.
Rehn also made clear that the ECB will not be dictated by market pricing, saying: “Market forces have priced in some rate hikes, but our policies are not dictated by the market forces. We take our decisions independently.”
The Commission outlined a more pessimistic alternative scenario in which the conflict drags on, causing energy prices to peak later in 2026 (with Brent crude potentially reaching $180 per barrel) before gradually normalizing by the end of 2027. In this case, inflation would remain elevated, and the economy would fail to rebound in 2027. European Economy Commissioner Valdis Dombrovskis said that under this adverse scenario, growth forecasts for this year and next would be roughly halved.
Worsening Public Finances and Regional Divergences
Weaker growth, higher interest rates, energy subsidy measures, and increased defense spending are expected to strain public finances. The euro zone budget deficit is projected to widen from 2.9% of GDP in 2025 to 3.3% in 2026 and 3.5% in 2027.
France, Germany, and Italy are all set to see larger deficits than previously forecast. Italy is expected to overtake Greece as the bloc’s most indebted country in 2027, with public debt reaching 139.2% of GDP.
Rehn highlighted important differences in exposure across the region, noting: “You have obviously quite different impacts of the energy price shock… Northern European countries, France and the Iberian Peninsula would be partly shielded… with Germany, Italy and Central Europe hit harder.”
Despite the challenges, the Commission emphasized that the euro zone is better prepared for this shock than the 2022 energy crisis caused by Russia’s invasion of Ukraine. Years of investment in energy diversification, renewables, and efficiency improvements have enhanced resilience. Policymakers have also been advised to avoid overly generous fuel subsidies that could further strain limited fiscal space.
The latest forecasts underscore the euro zone’s persistent vulnerability to external energy shocks and the delicate trade-off facing the ECB between controlling inflation and supporting growth. While a rate hike in June looks almost certain to safeguard credibility, further tightening must be carefully calibrated to avoid pushing an already fragile economy into recession.
Economists believe the duration of the Middle East conflict remains the single biggest risk factor. A swift resolution and reopening of the Strait of Hormuz would materially ease pressures. A prolonged war, however, risks creating stagflationary conditions, higher inflation combined with weaker growth, that would test both monetary and fiscal policy frameworks across Europe.
