Euro-area construction output was flat in July after a steep decline in June, while activity remained materially below its level a year earlier, highlighting continued weakness in building investment despite greater resilience in civil engineering.

Seasonally adjusted production in construction was unchanged in July from June across the euro area, according to first estimates released by Eurostat on September 18. Output had fallen 1.5% in June under the statistical agency’s revised figures. Across the broader European Union, construction production declined 0.3% in July after a 1.3% fall in June.

The annual comparison showed a clearer deterioration. Euro-area construction output was 2.0% lower than in July 2025, while EU output fell 1.8%. The euro-area decline was the steepest annual contraction since February and followed a revised 1.4% year-over-year decrease in June.

The figures show that the stabilization in monthly activity did not amount to a broad recovery. Instead, the aggregate was held back by pronounced weakness in the construction of buildings, while infrastructure-related civil engineering continued to perform more strongly.

Within the euro area, construction of buildings was unchanged from June in July. Civil engineering increased 0.6%, while specialised construction activities declined 0.1%. The combination left overall production flat for the month.

The annual sector breakdown was more divergent. Production in construction of buildings fell 6.4% from July 2025, continuing a prolonged period of weakness. Specialised construction activities, which include installation and finishing work as well as other specialised trades, declined 1.6%. Civil engineering increased 0.6%, providing the only positive contribution among the three broad construction categories.

The building segment has been the most persistent source of weakness throughout 2026. Eurostat’s revised data show annual building output falling 12.5% in February, 8.0% in March, 5.9% in April, 8.1% in May, 7.4% in June and 6.4% in July. Although the rate of contraction has eased from the most severe readings earlier in the year, activity remains substantially below year-earlier levels.

Civil engineering has followed a different path. Annual output moved from a 3.3% decline in February to increases of 4.8% in March, 3.8% in April and 3.4% in May, before remaining flat in June and rising 0.6% in July. The divergence suggests that infrastructure-related work has been more resilient than building construction, including residential and commercial projects that tend to be more directly exposed to financing conditions and private-sector demand.

The monthly data also showed large differences among individual European economies. Belgium recorded the strongest July increase among member states for which figures were available, with output rising 2.8%. Czechia followed with a 2.1% gain and Slovakia with a 1.9% increase. Romania rose 1.5%, while Germany, the euro area’s largest economy, posted a 0.9% monthly increase.

At the other end of the distribution, construction output fell 4.7% in Hungary. Poland and Sweden each recorded declines of 3.8%, and Austria fell 2.2%. Italy’s production decreased 1.4%, while Spain was down 0.4%. France edged 0.1% higher after a sharp 3.1% contraction in June.

The annual comparisons showed an even wider dispersion. Hungary recorded the largest decline at 12.2%, followed by Spain at 9.7% and France at 5.0%. Poland was down 2.5% and Italy declined 1.2% from July 2025.

Germany moved in the opposite direction, with construction output 1.0% above its year-earlier level. The Netherlands increased 2.6%, Portugal 1.9% and Romania 1.8%. The strongest annual gains were recorded in Finland, where production increased 12.8%, Slovenia at 11.6% and Bulgaria at 4.8%.

The divergence means the euro-area aggregate masks significantly different national construction cycles. Spain’s output remained well below year-earlier levels even after the pace of decline moderated from double-digit contractions earlier in 2026. France also remained under pressure, while Germany’s modest annual expansion marked a contrast with the declines recorded in several other large economies.

Revisions to June data added to the weak tone of the release. Eurostat revised the euro-area monthly change for June to a 1.5% contraction from the 1.3% decline initially reported in August. The annual change was revised substantially, to a 1.4% decline from the previously estimated 0.7% decrease.

For the EU, June’s monthly contraction was revised to 1.3% from 1.0%, while the annual figure was revised to a 0.5% decrease from an earlier estimate showing 0.2% growth. Those revisions emphasize the degree to which short-term construction estimates can change as additional national information becomes available.

Eurostat’s construction production index is designed to approximate changes in the volume of sector output rather than changes in nominal spending. The monthly euro-area and EU figures are calendar and seasonally adjusted, while the annual comparisons are calendar adjusted. The data are broken into construction of buildings, civil engineering and specialised construction activities under the European NACE business classification.

Private-sector survey evidence had already indicated that July remained difficult for the industry. S&P Global’s Eurozone Construction PMI, published in August, rose to 44.3 in July from 42.8 in June. Although that represented the slowest contraction in four months, the index remained below the 50 threshold separating expansion from contraction.

The survey also pointed to weak new business, with S&P Global reporting a marked deterioration in new orders and declines across residential, commercial and civil engineering activity in the countries covered by its survey. The official Eurostat data differ in methodology and coverage, particularly because they aggregate national production measures, but both sets of indicators point to a construction sector that remained under strain during the early part of the third quarter.

Financing conditions remain an important part of the outlook. The European Central Bank raised its three key interest rates by 25 basis points on September 10 as policymakers responded to renewed inflation pressures. Higher borrowing costs can weigh disproportionately on construction because residential development, commercial property and large capital projects commonly depend on long-duration financing.

Eurostat reported separately on September 17 that euro-area annual inflation rose to 3.2% in August from 2.9% in July. Energy made a significant positive contribution to the increase, adding to the cost environment confronting construction companies and other energy-intensive sectors.

ECB staff nevertheless expect housing investment to recover gradually over the medium term. In their September projections, officials said housing investment had grown notably less than previously projected during the first half of 2026, partly because of adverse weather and tighter financing conditions. Persistent housing demand and rising real wages were expected to support a gradual recovery, while renovation activity, including energy-efficiency improvements, was also expected to provide support.

The ECB’s projections also envisage investment benefiting from increased infrastructure, defence and artificial-intelligence-related spending. Government-backed infrastructure activity could therefore remain an important counterweight to weakness in residential and other private building categories. That pattern is broadly consistent with July’s Eurostat breakdown, in which civil engineering was the only major construction category to post both monthly and annual growth in the euro area.

The wider macroeconomic backdrop is stronger than the construction figures alone would suggest. ECB staff project euro-area real GDP growth of 0.9% in 2026, accelerating to 1.4% in 2027 and 1.5% in 2028. Investment overall is projected to expand 1.8% this year and 2.0% in each of the following two years. That outlook depends partly on infrastructure spending and an eventual improvement in housing investment.

Construction therefore represents a potential source of both weakness and upside risk for the broader economy. If building activity remains depressed, it could limit the contribution of fixed investment to growth and weigh on construction employment, materials demand and related professional services. A sustained improvement in infrastructure and housing activity, by contrast, could reinforce domestic demand as financing conditions and real household incomes evolve.

For now, the July figures provide limited evidence of such a turnaround. The flat monthly reading stopped the sharp decline recorded in June but did not reverse it. The euro-area seasonally adjusted construction index stood at 102.7 in July, unchanged from June and below its March level of 104.2.

The sector’s trajectory has also been volatile during 2026. Total euro-area construction production fell 0.6% month over month in February, surged 1.9% in March, was unchanged in April, increased 0.1% in May, contracted 1.5% in June and then stalled in July. That sequence makes it difficult to identify a sustained short-term direction from monthly changes alone.

The annual measure gives a more consistently weak picture. Euro-area output was down 4.1% from a year earlier in February, 0.5% in March and 0.1% in April. It briefly returned to 0.5% growth in May before falling 1.4% in June and 2.0% in July.

Investors and policymakers will therefore be watching whether upcoming data show civil engineering continuing to offset depressed building construction, and whether the stabilization in July develops into a broader improvement during the third quarter. Eurostat is scheduled to publish August construction production figures on October 20.

Until then, July’s release points to a sector that has stopped deteriorating on a month-to-month basis but remains materially weaker than a year ago. Infrastructure activity is providing some resilience, but the 6.4% annual fall in building construction and substantial declines across several major member states show that the euro-area construction recovery remains incomplete.
