The value of applications for investment promotion in Thailand from January to September 2025 increased 94 percent on year in value to 1.37 trillion baht, or about US$ 42.2 billion, according to the Thailand Board of Investment (BOI).

BOI Secretary General Narit Therdsteerasukdi said that the number of applications for investment promotion in the nine-month period rose by 23 percent to 2,622 projects, from 2,137 projects in the previous year.

The sectors that saw the highest value of investment applications were (1) digital, (2) electronics and electrical appliances industry, (3) electricity generation from renewal energy sources, (4) automotive and parts, (5) agriculture and food processing, (6) petrochemicals and chemicals, (7) medical services, and (8) tourism.

The period also saw the number of foreign direct investment applications grow by 82 percent in value to 985.3 billion baht. Singapore was the largest group of foreign investors, with a combined investment value of 359.8 billion baht, followed by Hong Kong, 237.3 billion baht, China, 142.9 billion baht, the United Kingdom, 100.3 billion baht, and Japan, 73.8 billion baht.

The BOI Secretary General said, “The fact that the value of investment applications we received in the first nine months of 2025 is already 22 percent higher than applications for the whole of 2024 shows that investors recognize Thailand’s economic potential. This also reflects the success of our commitment to hi-tech sectors at the heart of our investment strategy.” 

He said that BOI was pushing for the establishment of a mechanism, known as "Thailand FastPass," to accelerate the implementation of significant investment projects, under the Government’s “Quick Big Win” policy to stimulate the Thai economy through investments.
