Türkiye’s industrial production index fell by 2.2% month-over-month in September 2025, marking the sharpest contraction since April, while rising 2.9% compared to the same month a year earlier, according to data released by the Turkish Statistical Institute (TurkStat).
The seasonally and calendar-adjusted figures show that while industrial activity slowed compared to August, annual growth remained positive thanks to continued momentum in key sectors such as mining and manufacturing.
Among industrial subsectors, mining and quarrying output rose 1.2% on a monthly basis and 3.1% year-over-year. The manufacturing sector—which accounts for the majority of Türkiye’s industrial output—declined 2.3% from the previous month but increased 2.7% compared with September 2024.
Meanwhile, the electricity, gas, steam, and air-conditioning production and distribution sector posted a 5.3% annual rise but contracted 2.4% month-over-month.
By main industrial groupings, high-technology manufacturing recorded the strongest performance, surging 29% annually and 15.4% month-on-month. Capital goods output also grew 12.2% year-over-year, though it dropped 3.9% from August.
In contrast, the production of durable consumer goods fell 7.5% compared with a year earlier, reflecting softer domestic demand amid tighter financial conditions.
The latest Istanbul Chamber of Industry (ISO) Türkiye Manufacturing PMI survey also pointed to ongoing weakness in the industrial sector, aligning with the official data showing a September slowdown.
The PMI—a key gauge of manufacturing activity, where readings above 50 indicate growth and below 50 signal contraction—slipped to 46.5 in October from 46.7 a month earlier, hitting a three-month low. The results highlighted continued declines in new orders and production, with firms facing persistent cost pressures and raising prices despite subdued demand.
