Economic activity in the euro zone slowed sharply in March, as the S&P Global flash purchasing managers' index (PMI) dropped to 50.5, marking a 10-month low for private sector output and falling below economists' expectations of 51.0 according to a Reuters poll [1]. The PMI decline signals a significant downturn, with the 50.0 threshold separating expansion from contraction territory [1]. This slowdown has triggered fresh warnings of stagflation—a combination of high inflation, unemployment, and stalling growth—especially as the ongoing war in the Middle East drives energy prices higher and disrupts supply chains [1]. Chris Williamson, chief business economist at S&P Global Market Intelligence, stated, "The flash Eurozone PMI is ringing stagflation alarm bells as the war in the Middle East drives prices sharply higher while stifling growth. Firms' costs are rising at the fastest rate for over three years amid the surge in energy prices and choking of supply chains resulting from the war. Supplier delays have jumped to their highest since mid-2022, largely linked to shipping issues" [1].
Euro zone companies surveyed by S&P Global scaled back hiring marginally during March, as bosses lowered output expectations for the year compared to February forecasts [1]. The stagflation risk poses a dilemma for central banks, as traditional tools to combat inflation—such as raising interest rates—can further stifle growth and employment, while lowering rates may boost growth but risk increasing inflation [1]. The turmoil in the Middle East has rendered previous growth and inflation forecasts largely obsolete, with businesses and policymakers struggling to predict input costs and inflation amid uncertainty over the conflict's duration [1].
In revised forecasts released last week, the European Central Bank now expects economic growth of 0.9% in 2026 and headline inflation to average 2.6% this year [1]. However, S&P Global's Williamson cautioned that the PMI survey's price gauge indicates inflation accelerating close to 3%, with cost pressures likely to further increase selling price inflation in the coming months [1]. J.P. Morgan's Raphael Brun-Aguerre added, "Overall, the survey points to a large near-term inflation impact from higher energy that could feed into core prices" [1].
The outlook for the euro zone depends heavily on the duration of the war and its lasting impact on energy and supply chains. Williamson emphasized that the flash PMI data underscore how the European Central Bank is no longer in a 'good place' with respect to growth and inflation [1].
CONCLUSION
The euro zone is facing heightened stagflation risks as PMI data signals a sharp slowdown in economic activity and surging energy costs amid the Iran war. Revised ECB forecasts may be optimistic, with analysts warning of further inflation acceleration if supply chain disruptions persist. The market takeaway is a high level of uncertainty and concern for growth and inflation, with central banks facing tough policy choices.
