International Business News – In September 2025, private investment in Thailand fell by 4.5% compared to the previous month, marking the largest decline since December 2023 and exceeding the 0.2% drop recorded in August. The primary reason for the decline was a reduction in machinery and equipment investment, reflecting a decrease in imports of capital goods for domestic use, particularly in communication equipment.
Automotive investment also declined, mainly due to a drop in the import value of aircraft, despite an increase in registrations across all vehicle categories.
Meanwhile, construction investment saw a slight increase, supported by industrial plant projects.
