Thailand’s S&P Global Manufacturing PMI rose to 54.3 in September 2026 from 53.8 in August, marking its highest reading since December 2025. Output expanded at its fastest pace in nine months amid robust demand, while new orders grew at their strongest rate in six months, supported by promotional campaigns and new client acquisitions. Employment edged lower as firms cited natural attrition. Input-cost inflation and output-price growth remained modest, although higher raw-material expenses, particularly for metals, lifted input costs. Business confidence was little changed from August’s seven-month high, with manufacturers broadly optimistic that marketing initiatives and sustained demand would support production growth over the coming year.
