The euro zone's commercial activity picked up pace in September, as the broader European economy demonstrated stronger-than-anticipated performance in the face of elevated energy prices and ongoing disruptions stemming from conflicts in Ukraine and the Middle East.

The latest S&P Global business survey found that commercial activity across the euro zone expanded at its fastest pace in more than three years. Growth was widespread, with output expanding across both the manufacturing and services sectors.

The S&P Global Flash Euro Zone Composite PMI Output Index climbed to 53.1 in September, up from 52.0 the previous month. When the figure exceeds 50, the sector is considered to be in growth territory. The reading surpassed analyst expectations of a decline to 51.7, with eurozone businesses broadly holding their ground against persistent pressures from high energy prices and fractured supply chains.

The better-than-forecast data have nonetheless prompted analysts to examine whether the European economy can sustain its current pace, given that elevated energy prices are weighing on both businesses and households.

Economic activity picked up across several of Europe's larger economies. The country's leading economy recorded growth in September, with businesses navigating rising operational costs tied to inflationary pressures. Activity in France also picked up, with the pace of expansion hitting a two-year high on the back of a rebound in services demand.

Progress in the two biggest euro zone economies carries particular relevance given the prolonged economic headwinds both have navigated over recent years. Sustained expansion in commercial activity has the potential to bolster broader economic growth across the euro zone, provided the momentum holds.

Conditions in Britain, which operates outside the European Union, told a different story. Economic output eased in September as price pressures mounted, adding to the challenges facing the administration ahead of its forthcoming budget.

Fresh orders across the eurozone rose at their quickest rate in over four years, buoyed by a pickup in exports and heightened commerce within the single currency area. The services sector posted a gain as well, with activity climbing to a near-year peak and surpassing analyst forecasts. Production levels held largely steady.

Firms expanded their workforces in response to growing consumer demand, a pattern that points to broader economic activity feeding through into the labour market.

Elevated energy prices continue to draw attention as an ongoing issue. Businesses noted higher production expenses as energy costs climbed in the wake of hostilities between the United States and Iran. Certain businesses transferred those elevated expenses to consumers, adding upward pressure on prices.

Rising growth alongside elevated inflation leaves the European Central Bank navigating a notably complex set of monetary policy trade-offs. Recent figures are set to add complexity to the ECB's interest rate deliberations. Two interest rate increases have been implemented by the monetary authority so far this year, aimed at addressing inflationary pressures driven by elevated energy prices. The body also warned that price pressures may prove more stubborn than earlier forecasts anticipated.

Recent business surveys point to the euro zone economy having greater resilience to elevated borrowing costs than earlier forecasts had allowed for. Simultaneously, elevated costs for both inputs and outputs may constrain the ability of monetary authorities to loosen financial conditions should inflationary pressures extend further across the broader economy.

Traders have priced in three further ECB rate hikes through to the end of June 2027. Recent purchasing managers' index data have reinforced market expectations that policymakers may leave additional interest rate increases as an option, particularly where output growth persists alongside above-target price pressures.

September's economic data for Europe came in ahead of what analysts had forecast. Expansion across the services sector, stable industrial production, a rise in new orders, and broader workforce hiring collectively indicate that companies are holding their ground amid persistently high energy prices.

That durability remains exposed to shifts in international energy markets. Prolonged high energy costs may leave businesses weighing harder trade-offs across spending, staffing, and pricing decisions. Consumer spending power may face added strain in the period ahead.

At present, the European economy shows signs of weathering the disruption more robustly than analysts had anticipated. Policymakers face the question of whether the upturn recorded in September marks a lasting shift in trajectory or simply a brief pause before rising energy prices begin to constrain economic output.
