Business activity across the eurozone strengthened considerably in September 2026, signaling renewed momentum in the region’s private sector. Expanding demand, stronger service-sector performance and improving manufacturing conditions helped lift a key economic indicator to its highest level in more than three years.

However, the stronger outlook comes with an important complication: inflationary pressures have intensified, particularly as energy costs increase.

Business Activity Records a Strong Expansion

The S&P Global Eurozone Composite Purchasing Managers’ Index (PMI), which measures activity across manufacturing and services, climbed to 53.1 in September from 52.0 in August. The reading was the highest since April 2023.

A PMI reading above 50 indicates that business activity is expanding, while a reading below that threshold signals contraction. The September result therefore points to strengthening private-sector conditions rather than a broad-based economic decline. The services sector provided an important contribution to the improvement. Its PMI increased to 53.0 from 51.6 in August, reaching its strongest level in ten months.

Services and Technology Support Demand

Service-sector activity benefited from stronger demand across several business activities. Technology-related services received support from continued investment in artificial intelligence infrastructure and related digital capabilities. Spending on computing systems, software and specialized services can generate demand across interconnected industries. Companies investing in digital infrastructure may also increase purchases of consulting, maintenance and other professional services.

These developments illustrate how investment in one area can support activity elsewhere in the economy. However, the benefits are unlikely to be distributed evenly, as businesses differ in their exposure to technology spending and their ability to attract new customers.

Stronger demand also does not automatically guarantee sustained expansion. Companies must continue securing new orders, controlling costs and maintaining productivity to convert improved activity into lasting revenue growth.

Manufacturing Shows Signs of Improvement

Manufacturing also contributed to the broader improvement in business conditions. Better demand for industrial products and investment-related goods supported output, although performance remained uneven across industries.

Manufacturers face several competing pressures. Stronger orders can encourage production and investment, but higher energy prices, transportation expenses and financing costs may reduce profit margins. Companies can respond by improving production efficiency, negotiating supplier contracts or adjusting prices. However, businesses with limited pricing power may find it difficult to pass higher costs on to customers without weakening demand.

Inflation Complicates the Economic Outlook

Despite stronger activity, inflation remains a major concern. Eurozone consumer inflation increased to 3.8% in September 2026 from 3.2% in August, according to the reported figures. Higher energy costs can affect inflation directly through household utility expenses and indirectly through transportation, manufacturing and distribution costs. Businesses facing persistent increases in operating expenses may eventually raise selling prices.

Expert Insight

Chris Williamson, chief business economist at S&P Global, commented on the September business survey in the organization’s published analysis: “Growth hit the highest since April 2023 amid a broad-based expansion of output.”

Implications for the European Central Bank

The combination of stronger activity and higher inflation creates a challenge for the European Central Bank (ECB). Strong demand can make it harder for price pressures to ease, while higher interest rates can increase borrowing costs and gradually restrain economic activity.

Policymakers must therefore assess whether inflation is temporary or becoming more persistent. Developments in wages, services prices, energy costs and inflation expectations will be particularly important when determining the appropriate monetary policy response.

Eurozone business activity strengthened in September 2026, with the composite PMI reaching 53.1, its highest reading since April 2023. Services performed strongly, while manufacturing also contributed to the broader improvement.

However, rising inflation and operating expenses create risks for the durability of the recovery. Businesses must balance expanding demand against higher production costs, while policymakers face the challenge of controlling inflation without unnecessarily weakening growth. The September figures provide encouraging evidence of economic resilience, but continued progress will depend on sustained demand, effective cost management and a gradual easing of inflationary pressures.
