The Thailand Board of Investment (BOI) reported that investment promotion applications from January to September 2025 totaled 1.37 trillion baht, or about USD 42.2 billion, a 94% increase compared with the same period last year. This marks the highest value on record since the agency’s establishment sixty years ago, driven largely by major foreign direct investment (FDI) projects in digital infrastructure and smart electronics manufacturing.
During the first nine months of 2025, the number of applications rose 23% to 2,622 projects, compared with 2,137 in the previous year. FDI projects accounted for 985.3 billion baht, or 72% of total investment value, representing an 82% year-on-year increase. According to BOI Secretary General Narit Therdsteerasukdi, the results reflect investor confidence in Thailand’s economic potential and the success of its focus on high-technology sectors.
The digital sector led with 119 projects, mostly data centers, totaling 612.8 billion baht. The electrical appliances and electronics sector followed with 382 projects worth 184.1 billion baht. The automotive and parts sector attracted 229 projects valued at 71 billion baht, while agriculture and food processing drew 228 projects totaling 47.2 billion baht. The petrochemicals and chemicals sector received 230 applications valued at 36.8 billion baht.
Singapore was the largest source of FDI with 359.8 billion baht, followed by Hong Kong, Mainland China, the United Kingdom, and Japan. Major data center investments included pledges from Beijing Haoyang Cloud Data Technology, Zenith Data Center and Cloud Services, and Galaxy Peak Data Center.
