BOI Extends Privileges to the Lending of Funds to Related Companies

On September 16, 2021, Thailand’s Board of Investment (BOI) published BOI Notification No. Sor. 3/2564, extending the scope of certain promoted activities to include lending money to related companies in Thailand and overseas.

The new notification brings these activities within the scope of “trade and investment support offices” (TISOs) and “international business centers” (IBCs)—two of the most popular categories of promoted activity under the BOI. Foreign-majority owned companies may now apply for either TISO or IBC promotion to cover lending funds to affiliates as an alternative to applying for a foreign business license, which can be less predictable. BOI-promoted companies that already have a BOI certificate in the TISO or IBC categories can amend the BOI certificate to cover this kind of lending activity.

The amended scope of the promoted activities for both TISO and IBC categories now provides more flexibility for BOI-promoted companies to provide financial services to their affiliates. Previously this was restricted—especially when foreign-majority-owned companies wished to lend money offshore.

Conditions

Under the new notification, promoted business activities under the TISO category now include lending to “affiliated and group companies,” while those under the IBC category now include lending to “associated enterprises.” These terms are defined separately in Thai laws and regulations, but in practice the definitions are very similar and generally refer to companies that share structural connections. Companies must check carefully to make sure that their proposed structure falls within the appropriate legal definition before applying to the BOI for investment promotion.

Lending business activities now permitted under the IBC and TISO categories include loans in foreign currencies to associated enterprises and affiliated and group companies located overseas, and loans in Thai baht to associated enterprises and affiliated group companies in Thailand. The new BOI notification also allows loans in Thai baht to associated enterprises and affiliated and group companies in Cambodia, Laos, Malaysia, Myanmar, and Vietnam for trading or business investment purposes in those countries or in Thailand.

A promoted company cannot conduct lending business exclusively, but must conduct at least one other TISO business activity or IBC business activity (excluding treasury center and international trade business activities), depending on the category of the promoted company. The scope of the lending business must not fall under the scope of a treasury center business as defined by the BOI and the Bank of Thailand (BOT). Moreover, offshore lending must still comply with BOT exchange requirements.

The two categories differ in terms of tax incentives—no tax incentives are available for TISO lending activities, while tax incentives for IBC projects depend predominantly on the criteria for the special tax incentives scheme as laid out by the Revenue Department (RD), which has not yet recognized lending as an IBC business activity under its own IBC tax scheme. While the full impact of this is still unclear, it could mean that revenue from a promoted lending business might not be eligible for tax incentives under the RD’s IBC tax scheme.

Foreign-majority owned entities in Thailand may not engage in any financial service business activity, except for exempted money lending to affiliated and group companies in Thailand as prescribed by the relevant ministerial regulation issued under the Foreign Business Act B.E. 2542 (1999), unless they are granted either a foreign business license or a foreign business certificate for this purpose. The chances of obtaining either of these are low.

Interest in data center land acquisition has increased significantly over the past year, with a notable rise in inquiries from investors seeking to establish digital infrastructure in Thailand. Although the sector is still in its early stages, this emerging wave of development represents a significant shift in Thailand’s technology infrastructure landscape, driven primarily by multinational technology companies and operators looking to expand their regional presence. Project Development The data center sector in Thailand is attracting a diverse range of international investors, though with clear geographic patterns. Most investors are from China, Singapore, and Japan, with some additional interest from countries outside Asia, including the United States and Europe. This investor base consists primarily of multinational tech companies and operators seeking to establish new facilities rather than acquire existing assets. Data center business activities are also a sector promoted by Thailand’s Board of Investment (BOI), which offers investors both tax and nontax privileges as well as exemptions to foreign investment and land-ownership restrictions. Projects currently underway are still largely in the land acquisition and construction phase. Unlike more mature markets where many facilities are operational and generating revenue, the predominant focus in Thailand remains on securing suitable land and beginning the building process. This means that while interest is high and land assembly is accelerating, the sector as a whole has not yet reached the operational phase that will ultimately drive licensing applications and full regulatory compliance. The licensing process itself remains at an early stage, as most projects must first complete their facilities before applying for the specific licenses required from the telecommunications authority. Once the facilities are built, the next critical step will be obtaining these telecommunications licenses, which are mandatory for data center operations. Legal and Regulatory Considerations The complexity of data center development in Thailand requires

Thailand and the United States signed a memorandum of understanding (MOU) titled “Cooperation to Diversify Global Critical Minerals Supply Chains and Promote Investments” on October 26, 2025, signaling a new strategic alignment aimed at developing Thailand’s mineral sector, particularly in rare earth elements (REEs). The MOU has implications for investments in technology, manufacturing, and other related sectors. This update outlines the key provisions of the MOU and the potential opportunities and legal navigating points for businesses. Objectives The primary driver of this agreement is the US initiative to diversify global supply chains for critical minerals and reduce reliance on current market leaders, particularly China. For Thailand, it represents a major opportunity to attract high-tech investment and develop its downstream processing industries. The cooperation is set to focus on five main areas: Technical knowledge: Exchange of technical expertise and international best practices to strengthen Thailand’s mining and processing sector. Joint cooperation: Establishing workshops, seminars, and scientific collaboration to boost innovation. Regulatory practice: Promoting good governance and streamlining regulatory and licensing procedures. Information sharing: Sharing data on potential projects and global market prices. Full-value chain: The MOU covers the entire mineral lifecycle, from exploration and extraction to processing, refining, and recycling. “First Opportunity to Invest” Clause The most debated provision within the MOU states that “participants expect to have the first opportunity to invest . . . in critical minerals assets that may be sold in Thailand.” Business implications: This clause is widely interpreted as granting US companies a first look or preferential access to investment opportunities in Thailand’s critical minerals sector. This could be a significant advantage for US-based or affiliated companies in mining, technology, and energy seeking to secure a foothold in a developing REE supply chain. Thai government position: Thai officials, including the prime minister, have publicly clarified

On September 29, 2025, Thailand’s Office of the Personal Data Protection Committee (PDPC Office) published its Regulations on the Review and Certification of Binding Corporate Rules B.E. 2568 (2025) (the Regulations). The Regulations provide clarity on the PDPC Office’s approach to reviewing and certifying binding corporate rules (BCRs) under Section 29 of the Personal Data Protection Act B.E. 2562 (2019) (PDPA), and aim to facilitate international data transfers within a group of undertakings or enterprises (a “corporate group”). In conjunction with this development, the PDPC Office also approved BCRs for two companies operating in Thailand on September 30, 2025. This milestone represents the first concrete progress since the PDPC’s Notification on Criteria for the Protection of Personal Data Sent or Transferred to a Foreign Country pursuant to Section 29 of the PDPA B.E. 2566 (2023) came into effect in March 2024. Some key features of the Regulations are set out below. Categorization of BCRs BCRs are classified into two types: (1) BCRs for Controllers (BCR-C) and (2) BCRs for Processors (BCR-P). The category must be clearly specified when submitting the BCRs to the PDPC Office. Documentation Requirement The applicant must prepare and submit the application (a standard template may be provided by the PDPC Office in the future) along with supporting documents for review and certification in the Thai language. If the supporting documents are in a foreign language, a certified Thai translation should be provided. The translation must be notarized by a notary public or qualified person. Supporting documents may include, among others, a binding instrument such as an intra-group agreement, or a list of entities subject to the BCRs. Expedited Process Requirement Organizations with existing BCR approvals under the EU or UK GDPR, or from countries announced by the PDPC under Section 28, may apply through an
