The Istanbul Chamber of Industry Türkiye Manufacturing PMI slipped to 47.9 in September 2026 from 48.1 in August, remaining below the 50.0 threshold for the thirtieth consecutive month and signaling a continued contraction in the sector. New orders weakened further and overall demand stayed subdued, weighed down by uncertainty related to the conflict in the Middle East. In turn, manufacturers cut production for the fourth month running. Firms also reduced employment, purchasing activity, and inventories as they scaled back operations in line with softer demand and weaker inflows of new business.
On the price front, input cost inflation quickened to a four-month high, reflecting higher fuel, energy, and transportation costs associated with tensions in the Middle East, as well as rising raw material prices. In response, manufacturers raised their selling prices at a faster pace, passing increased costs on to customers.
