Industrial production - January 2026

The industrial production indices are calculated using the chaining method introduced starting from the publication of the data relating to the month of January 2022.

From January 2026, the calculation base is set to the year 2025, while the reference base, in line with the other short term indicators, remains the year 2021. Indices are produced according to Ateco 2007 classification (Italian edition of Nace Rev. 2).

The purpose of this review and any resulting updates is to guarantee that the indices remain robust and to adapt them to economic or technical developments, in particular by including the monitoring of new products and by eliminating those whose production has become irrelevant. Furthermore for the branches monitored in working hours, productivity coefficients have been revised.

Finally, the seasonal and working day adjustment (SA-WDA) models have also been revised over the recent past to improve the quality of the indices. The methodological aspects connected to the update of the 2025 calculation base are illustrated in the Information Note released together with this flash statistic.

In January 2026 the seasonally adjusted industrial production index decreased by 0.6% compared with the previous month. The change of the average of the last three months with respect to the previous three months was +0.7%.

The calendar adjusted industrial production index decreased by 0.6% compared with January 2025 (calendar working days being 20 versus 21 days in January 2025).

The unadjusted industrial production index decreased by 3.6% compared with January 2025.
