Turkish manufacturing shrinks in October: what plants should do now

The Istanbul Chamber of Industry Türkiye Manufacturing PMI, compiled by S&P Global, fell to 47.3 in October 2026 from 47.9 in September, the fastest contraction since June. Any reading below 50 means contraction.

Output fell for a fifth month, at the fastest pace in four months, and new orders declined for a 40th consecutive month, with export orders still softening. Input costs and output prices kept rising sharply, though less than in September; 29% of respondents blamed oil, raw materials and exchange-rate weakness. Supplier delivery times lengthened again, extending a full year of deterioration.

S&P Global's Andrew Harker said manufacturers “continued to find it difficult to generate growth” as the final quarter began.

A hard combination: weak demand, slow supply

Weak demand plus longer supplier lead times pushes many plants into two mistakes: producing big batches “just in case”, so finished stock piles up, or cutting quality and maintenance staff to save cost, so defects and breakdowns rise. Both hurt margins.

What works in a downturn

• Produce to real demand: smaller batches and faster delivery instead of stocking finished goods that may not sell.
• Cut changeover time (SMED): it is what makes small batches economical.
• Smart material safety stock: with longer lead times, protect only critical materials.
• Use spare capacity: quieter machine time is a chance for preventive maintenance and short Kaizen events.
• Don't cut quality: in a weak market, a customer lost to a defect rarely comes back.

Prepare for the recovery now

Manufacturers still expect output to rise over the coming year, even though confidence slipped to a three-month low. The plant that uses this period to cut waste and standardise work will respond fastest when demand returns.

Takeaway: you can't control demand or material prices, but you do control scrap, changeover time and delivery quality. Those are your tools right now.
