Thailand has secured over $4.1 billion in investment pledges for its electric vehicle (EV) supply chain, reinforcing its status as Southeast Asia’s leading automotive manufacturing hub. The Thailand Board of Investment (BOI) announced that the capital injection spans 198 projects, covering battery electric vehicles (BEVs), hybrid systems, battery manufacturing, critical components, and charging infrastructure.

The investment surge is part of a strategic shift by global automakers to diversify supply chains and establish regional hubs in Southeast Asia. Unlike its regional competitors, Thailand’s policy framework supports a transition across all major propulsion technologies, including Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs), and BEVs. “We must choose to be builders, not just consumers,” said Narit Therdsteerasukdi, Secretary General of the BOI, at the International Electric Vehicle Technology Conference in Bangkok.

In 2025, electrified vehicles accounted for over 40% of all new vehicle registrations in Thailand, with HEVs leading at 21.8%, closely followed by BEVs at 19.6%. The $4.1 billion investment pipeline is highly distributed, showing deep integration across the supply chain. Notably, BEVs received $1.18 billion across 18 projects, establishing an annual domestic production capacity of over 370,000 units.

Major global automakers, including Mercedes-Benz, BYD, and Hyundai, have localised production in Thailand, creating over 16,000 local jobs. The BOI has facilitated joint ventures and matchmaking through 18 Sourcing Day events, pairing Thai parts manufacturers with multinational automakers, generating over $1.79 billion in domestic procurement value. “Our goal is to ensure that local industry and workforce are the ones driving this next chapter of growth,” Therdsteerasukdi added
