The S&P Global Flash Eurozone Composite PMI fell to 50.5 in March, down from 51.9 in February, hitting a 10-month low and leaving the eurozone's private sector barely above the 50.0 threshold that separates expansion from contraction. The number is bad. The trend is worse. And the details underneath the headline are alarming.
France has now been contracting for three consecutive months, with its composite PMI sinking to 48.3. Both manufacturing output and services activity fell, with the services sector posting its fastest decline since October 2025. Germany, the eurozone's largest economy, managed to stay just above the waterline at 50.9, but its manufacturing sector remains firmly in contraction at 48.3. The only major economy showing genuine resilience is Spain, and even there, momentum is fading.
The Energy Stranglehold
The primary driver is energy costs. Input prices across the eurozone are rising at the fastest rate in more than three years, driven almost entirely by the Iran conflict and its impact on global energy supply chains. Brent crude, which briefly dipped below $100 last week on hopes of a diplomatic pause, has already bounced back above $104. European natural gas futures are at levels not seen since the worst of the 2022 energy crisis.
For European businesses, this is not a temporary shock. It is a cost structure that has fundamentally changed. Manufacturers are passing costs to consumers where they can and absorbing losses where they cannot. Either way, margins are being destroyed, investment is being deferred, and hiring has stalled.
The Stagflation Trap
The word that keeps appearing in analyst notes is stagflation — the toxic combination of stagnant growth and persistent inflation that central banks cannot fix with a single policy lever. Cut rates to support growth, and you risk fuelling inflation. Raise rates to fight inflation, and you risk tipping the economy into outright recession.
The ECB is trapped. Its staff projections published earlier this month already raised the inflation forecast to 2.6% and slashed the growth outlook. The March PMI data suggests even those revised projections may be too optimistic. ECB President Christine Lagarde has maintained that the bank will act "as the data requires," but the data is now requiring two contradictory things at once.
What Comes Next
If the Iran conflict continues — and there is no credible sign it will end soon — Europe faces a summer of deteriorating economic conditions. Consumer confidence is already falling. Business investment is on hold. The labour market, which had been the eurozone's one bright spot, is starting to show cracks, with hiring intentions in France and Italy turning negative for the first time since 2024.
The eurozone is not collapsing. It is slowly suffocating, and the oxygen supply — cheap energy — is controlled by events in the Persian Gulf that no European leader can influence. That is the most dangerous kind of economic crisis: one where the patient is getting sicker and the doctors have no medicine that works.
