Industrial production in Taiwan rose 19.17% year-on-year in September 2026, slowing from 23.47% in the previous month. This marked the weakest annual growth since May, with manufacturing output easing to 20.21% from 24.61%, despite strong gains in computers and optoelectronics (45.92%) and electronics (23.62%), driven by continued robust demand for AI servers, high-performance computing and semiconductors. Machinery production also increased 26.02% amid semiconductor capacity expansion, while base metal output rose 1.39%. In contrast, chemical materials and fertilizer production fell 4.29% due to weaker demand and annual maintenance, while automotive and auto parts output grew 2.35%.
