Eurozone construction output fell 0.7% year-on-year in June 2026, while seasonally adjusted activity dropped 1.3% from May. The monthly decline, reported by Eurostat, was the sector’s sharpest of the year and reversed the previous month’s increase. Building construction remained the main drag, contracting 6.5%, while growth slowed in civil engineering and specialized construction. France, Belgium and Spain recorded significant declines. Construction, which accounts for roughly 5%-6% of eurozone GDP, remains sensitive to European Central Bank interest rates, financing costs and demand for new projects. Economists will watch upcoming data to determine whether June’s setback is temporary or signals a prolonged slowdown.
