Thailand's foreign and domestic investment applications rose 37% year-on-year to $43.6 billion (approximately 1.47 trillion baht) in the first half of 2026, fueled by a wave of capital flowing into digital infrastructure and artificial intelligence (AI) data centers, according to the Thailand Board of Investment (BOI). The surge comes amid global headwinds including geopolitical tensions, energy price volatility, and supply chain restructuring, positioning Thailand as a preferred investment base in Southeast Asia.
The digital sector led the capital influx, accounting for $33 billion (about 1.12 trillion baht) in investment applications. “Thailand's investment growth held steady even as the world economy faced real turbulence,” said Narit Therdsteerasukdi, Secretary General of the BOI. “This reflects strong investor confidence in Thailand's potential as a base for the industries of the future.”
Other high-value industries also attracted significant capital. The electrical appliances and electronics sector drew $3.56 billion (120.2 billion baht) across 179 projects, while agriculture and food processing secured $1.82 billion (61.4 billion baht) across 131 projects. Logistics and high-value services attracted $1.19 billion (40.2 billion baht) across 170 projects, and the automotive sector drew $759.2 million (25.7 billion baht) across 122 projects. Additional sectors included mining, metals and materials ($603.5 million), chemicals and petrochemicals ($489.1 million), and machinery, automation and robotics ($387.4 million).
Foreign direct investment (FDI) applications drove the bulk of the growth, skyrocketing 80% year-on-year to $40.5 billion (1.37 trillion baht) across 877 projects. Singapore was the top FDI source at $33.2 billion (1.12 trillion baht) across 158 projects, followed by the United Kingdom ($1.40 billion), China ($1.35 billion), Taiwan ($1.12 billion), and Japan ($970.1 million). Investments were concentrated in digital technology, including data centers, data hosting, cloud services, electronics, and advanced manufacturing components.
Geographically, Thailand's industrialized Central region claimed the largest share of capital at $26.7 billion (903.8 billion baht) across 513 projects, followed by the Eastern region at $14.7 billion (495.7 billion baht). The Northern region saw investment value rise 93% year-on-year, led by energy, agriculture, and medical projects.
To support the massive power requirements of next-generation data centers, Thailand is seeing a parallel surge in renewable energy infrastructure. The energy and utilities sector recorded 221 projects worth $1.17 billion (39.5 billion baht), including 198 clean energy initiatives valued at $779.7 million (26.4 billion baht). Concurrently, under the BOI's “Smart and Sustainable Industry” initiative, companies submitted 132 applications valued at $507.6 million (17.2 billion baht) to upgrade machinery and integrate automation and robotics, boosting productivity and sustainable manufacturing.
The projects approved in the first half of 2026 are expected to generate over 82,000 jobs for Thai workers and consume approximately $11.4 billion (386 billion baht) in domestic raw materials annually, accounting for 42% of total raw material use. They are also projected to boost the nation's export capacity by more than $36.8 billion (1.24 trillion baht) per year. The BOI approved investment promotion applications for 1,300 projects valued at $38.7 billion (1.31 trillion baht) in the period.
“Investment value is not the only goal,” Narit said. “Real success means quality jobs, higher skills, and better income for Thai workers. It means real opportunities for Thai businesses inside the supply chain, and growth that reaches every region.” He emphasized that the BOI will continue to push for rapid investment implementation through the Thailand FastPass mechanism, driving economic growth and allowing Thai people to share in the shift to future industries.
