The Board of Investment (BOI), Thailand's main investment promotion agency, reported on 13 November 2026 that actual investment by promoted projects in the third quarter of 2026 reached 260,680 million baht. That is up 28% from the same period last year. For the first nine months of the year, actual investment totalled 796,540 million baht, up 27%. The figure is money that projects have already spent on machinery, construction, and land and other items. It is not the value of applications for investment promotion.
The data is useful for business people who hope to supply new factories, for anyone following the Thai economy, and for those watching the job market in target industries. It shows how much money projects that receive BOI privileges have really started putting into machinery and construction. The largest share went to digital and electronics, and 89% of the quarter's total went to machinery and construction.
Actual investment means money already spent
Narit Therdsteerasukdi, the BOI's secretary-general, said many projects have moved from the planning stage into real operation. Actual investment therefore refers to money that has gone in, not a plan that was applied for or a ceiling that was approved.
The BOI has upgraded its tracking of actual investment to a quarterly basis, in line with government policy. This lets the public see how the money is progressing every quarter instead of waiting for a full-year total.
Latest progress and the full-year outlook
The BOI expects actual investment for the whole of 2026 could pass 1 trillion baht. In 2025, actual investment totalled 865,000 million baht. The 1 trillion baht figure is only the BOI's expectation. It has not happened yet.
Based on the nine-month total of 796,540 million baht, the final quarter would need another 203,460 million baht of actual investment to reach exactly 1 trillion baht. That is less than the 260,680 million baht recorded in the third quarter. The real fourth-quarter figure will have to wait for the next BOI report.
Digital and electronics take nearly half
By industry, the digital group had the highest actual investment in the third quarter at 64,180 million baht, more than 7 times the level of the same period last year. Electronics and electrical appliances followed with 61,170 million baht, up 20%. Together the two groups account for more than 125,000 million baht, or nearly half of the quarter's actual investment.
Other groups with actual investment in the quarter were:
- Agriculture and food processing: 27,072 million baht
- Energy and basic utilities: 23,988 million baht
- Automotive and parts: 18,181 million baht
- Minerals, metals and materials: 15,227 million baht
- Tourism: 11,193 million baht
The money is therefore not spread evenly. The top two groups are well ahead of the rest, and each of the remaining groups received less than 30,000 million baht. Companies and farmers in the supply chains of these industries can compare their own sector with the overall picture to see whether actual spending in their field is larger or smaller than elsewhere.
Machinery and construction are the big items
By type of spending, growth came mainly from machinery and construction. In the third quarter, machinery investment was worth 136,500 million baht, up 37%. Construction was worth 96,279 million baht, up 39%. Together they make up 89% of total actual investment. Land and other items came to 27,906 million baht, about 11%. Machinery alone is more than half of the quarter's total, and construction grew slightly faster than machinery.
The high share of machinery and construction suggests projects are starting to commit real money. The BOI uses a mechanism called Thailand FastPass to help speed up these projects.
The figures have limits. They cover only projects that receive BOI promotion, not all investment in the country. They show how much money has been spent, but not how many jobs were created. They are also a different data set from the number of applications, so the two cannot be compared directly.
When the BOI reports again, readers can compare three things: the quarterly total, the share of machinery and construction, and which industry groups take the lead.
