More specifically, the General Price Index of Construction Materials for New Residential Buildings, with base year 2021=100.0, recorded an increase of 4.3% in May 2026 compared with the same month of 2025. This increase is higher than that recorded one year earlier, as in May 2025 the index had risen by 3.1% compared with May 2024.
On a monthly basis, the index increased by 0.5% in May compared with April 2026, compared with a rise of 0.3% recorded in the corresponding monthly comparison in 2025.
At the same time, the average index for the twelve-month period June 2025 – May 2026 increased by 2.7% compared with the corresponding twelve-month period June 2024 – May 2025. However, the rate of increase shows signs of deceleration, as during the previous corresponding period an increase of 4.7% had been recorded.
The data indicate that, despite a degree of annual moderation, the cost of construction materials continues to rise, affecting both the cost of new residential construction and investment activity in the real estate and construction sectors.
