How Thailand's 2026 Foreign Business Act Reforms Affect Lending and Cross‑border Financing, Practical Guidance for Lenders and Foreign Investors

Last updated: June 20, 2026

Lending to foreign companies in Thailand has entered a new era of regulatory complexity. The 2026 amendments to the Foreign Business Act (FBA), combined with intensified enforcement by the Department of Business Development (DBD) and fresh Cabinet resolutions reclassifying restricted activities, have fundamentally altered the credit‑risk calculus for international banks, private equity sponsors and corporate lenders extending finance to Thai borrowers with foreign ownership. This article provides a lender‑first transaction playbook, covering enhanced due diligence, covenant redesign, security validity, and practical mitigation routes, so that credit officers, in‑house counsel and CFOs can protect their positions immediately. For a broader overview of the statute itself, see the Thailand Foreign Business Act 2026 summary on this site.

• Immediate action required. Review every existing facility agreement where the borrower is a Thai entity with direct or indirect foreign ownership exceeding 49 per cent or where nominee shareholding structures are in place.
• Covenant audit. Standard ownership and compliance warranties drafted before the 2026 reforms are almost certainly insufficient; enhanced anti‑nominee and material‑adverse‑change clauses are now essential.
• Security validation. Share pledges, mortgage registrations and receivables assignments may all be challenged where the pledgor’s lawful shareholding is disputed by the DBD.
• BOI and treaty routes remain viable but carry additional documentation and ongoing compliance burdens that must be verified at drawdown and monitored throughout the facility life.

Quick Primer, What Changed in the Foreign Business Act 2026

The Foreign Business Act B.E. 2542 (1999) has long restricted foreigners from operating certain categories of business in Thailand unless they hold a Foreign Business Licence (FBL) or qualify for specific exemptions. The 2026 round of amendments, published in the Royal Gazette and effective in stages, represents the most significant overhaul of foreign ownership restrictions in Thailand since the original statute.

Three changes matter most for anyone involved in lending to foreign companies in Thailand. First, the Cabinet resolution reclassifying and delisting several activities from Lists Two and Three of the FBA expanded the range of sectors that foreigners may enter without an FBL, but simultaneously tightened scrutiny on activities that remain restricted. Second, the DBD intensified its administrative enforcement against nominee shareholder arrangements, issuing orders that require enhanced disclosure of beneficial ownership and authorising investigations into historical shareholder transfers. Third, amendments to the FBL application process imposed stricter capital adequacy and local presence requirements on foreign applicants, raising the operational cost of legitimate market entry.

Timeline of Key Legislative and Administrative Steps

Which Activities Were Delisted or Reclassified

Several service‑sector activities, including certain categories of wholesale and retail trade, specific IT services, and selected construction‑related activities, were moved off the restricted lists, allowing full foreign ownership without an FBL. Conversely, activities related to agriculture, land‑based resource extraction and certain financial intermediation services saw tightened restrictions or new conditions. For lenders, the critical question is whether the borrower’s principal revenue‑generating activity has been reclassified: a shift from List Three to List Two, for instance, increases the regulatory burden and may invalidate an existing FBL or trigger a mandatory licence upgrade.

Immediate Credit‑Risk Consequences for Lenders

The 2026 Foreign Business Act reforms translate into three categories of credit risk that affect any institution involved in lending to foreign companies in Thailand: borrower legality risk, security and perfection risk, and enforcement complications arising from nominee shareholder disputes.

Scenario A, Nominee Shareholding Discovered Post‑Drawdown

A Thai limited company borrower has 51 per cent Thai and 49 per cent foreign shareholding on paper. Following a DBD investigation, the Thai shareholders are found to be nominees, individuals without genuine economic interest who hold shares on behalf of the foreign investor. The borrower is deemed to be operating a restricted business without an FBL, a criminal offence under the FBA carrying fines and potential imprisonment for directors. For the lender, the consequences are severe: the share pledge over Thai‑held shares may be contested because the pledgor’s legal ownership is in dispute; distributions and dividends may be frozen; and the borrower’s corporate status could be subject to dissolution proceedings.

Scenario B, Borrower’s Activity Reclassified

A borrower previously operating freely under a delisted activity discovers that the 2026 amendments have reclassified its business into a restricted list. It must now obtain an FBL or restructure. During the transitional period, the borrower may be technically in breach of the FBA, creating a material adverse change under standard facility agreements and potentially rendering security interests unenforceable if the underlying business is found to have been conducted unlawfully.

Scenario C, BOI‑Promoted Entity or Treaty Route

BOI‑promoted companies and entities relying on bilateral investment treaty protections continue to enjoy exemptions from FBA restrictions, provided they maintain compliance with BOI conditions. However, any lapse in BOI compliance, failure to meet investment thresholds, employment targets or export obligations, can retroactively remove the exemption, exposing both the borrower and the lender’s security package to the same nominee shareholder risk as described in Scenario A. Industry observers expect the DBD to coordinate more closely with the BOI on compliance monitoring in 2026 and beyond.

Due Diligence Checklist for Lending to Foreign Companies in Thailand

Bank due diligence in Thailand must now go well beyond the conventional company search and director verification. The following checklist is designed for credit officers and in‑house counsel evaluating new facilities or refinancing existing ones in the post‑FBA‑2026 environment.

BOI and Treaty Documentation Checks

Where the borrower relies on a BOI promotion certificate, lenders should require a certified copy of the promotion certificate, the most recent BOI annual compliance report, and a legal opinion confirming that the borrower’s current operations remain within the scope of the promoted activity. For treaty‑route entities, a legal opinion on the applicability of the relevant bilateral investment treaty and its investor protections should be obtained before drawdown.

Beneficial Ownership and Nominee Detection Methods

Nominee shareholder risk in Thailand has historically been difficult to detect. Practical methods include cross‑referencing shareholder names against the DBD’s corporate registry to identify individuals who appear as shareholders in multiple foreign‑linked companies, requesting bank statements or tax returns from Thai shareholders to verify genuine economic interest, and conducting shareholder interviews (discussed below).

Shareholder and Director Interview Protocol

Lenders should consider requiring borrowers to make Thai shareholders and directors available for interview, either in person or by video conference, as a drawdown condition. Interview questions should focus on the shareholder’s understanding of the company’s business, their source of funds for share acquisition, and whether they have any side agreements relating to voting rights, dividend distribution or share transfer obligations. Any refusal or inability to provide coherent answers should be treated as a material red flag.

Borrower Covenants and Documentation, What to Add or Change

Standard loan documentation drafted before the Foreign Business Act 2026 reforms is unlikely to address the specific risks that these changes create. Lenders should consider the following enhanced borrower covenants for Thailand facilities.

Sample Ownership and Nominee Warranty

The following sample clause can be adapted for inclusion in facility agreements:

“The Borrower warrants and represents that (a) no shares in the Borrower are held by any person as nominee, agent or trustee for or on behalf of any Foreign Person (as defined in the Foreign Business Act B. E.

2542, as amended); (b) all shareholders appearing in the Borrower’s shareholder register are the true beneficial owners of the shares registered in their names and have acquired such shares using their own funds and for their own account; (c) no shareholder is party to any agreement, arrangement or understanding (whether written or oral) that would entitle any Foreign Person to exercise voting rights, receive dividends, direct the transfer of shares, or otherwise exercise control over such shares; and (d) the Borrower will immediately notify the Lender if any of the foregoing representations ceases to be true and accurate in any respect.

Enhanced Drawdown Conditions

In addition to the standard conditions precedent, lenders involved in cross‑border financing in Thailand should require the following before each drawdown:

• Legal opinion on FBA compliance. An updated legal opinion from Thai counsel confirming the borrower’s lawful status under the FBA as at the drawdown date.
• Beneficial ownership declaration. A director’s certificate confirming that no nominee arrangements exist and that all shareholders are genuine beneficial owners.
• BOI compliance certificate. Where applicable, confirmation from the borrower that all BOI promotion conditions continue to be met.
• No DBD investigation certificate. A declaration that the borrower is not subject to any pending or threatened DBD investigation, inquiry or enforcement action relating to nominee shareholding or FBA compliance.

Enforcement and Acceleration Triggers

The 2026 reforms justify adding the following specific events of default and acceleration triggers to facility agreements:

• Any finding, order or determination by the DBD that any shareholder of the Borrower holds shares as a nominee for a Foreign Person.
• Any reclassification of the Borrower’s principal activity under the FBA that would require the Borrower to obtain or upgrade an FBL, if such licence is not obtained within a specified cure period (typically 60–90 days).
• Any lapse, revocation or material amendment of the Borrower’s BOI promotion certificate or FBL.
• Any criminal prosecution, penalty or fine imposed on the Borrower or any of its directors under the FBA.
• A material adverse change clause specifically referencing changes in law or administrative practice affecting the Borrower’s ability to lawfully conduct its business in Thailand.

Suggested cure periods should be short, 30 days for notification failures, 60 days for FBL procurement, with automatic acceleration if the cure period expires without resolution. Escrow or blocked‑account provisions for loan proceeds may also be appropriate where nominee risk is elevated but the lender is willing to proceed on enhanced terms.

Security Interests in Thailand, Perfection Issues and Practical Guidance

The enforceability of security interests in Thailand depends on both the type of collateral and the legal status of the entity granting the security. The 2026 FBA changes introduce a new layer of risk that must be addressed in every security package.

Share Pledges and Nominee Holdings

A share pledge over shares held by a nominee presents a fundamental enforceability problem: the pledgor may not be the true owner of the pledged shares, and a court or the DBD may set aside the share register entry on which the pledge depends. Lenders should require a power of attorney to vote and transfer the pledged shares, coupled with an irrevocable instruction to the company’s share registrar, and should insist on express warranties from both the pledgor and the borrower confirming the absence of nominee arrangements.

Real Estate and Mortgage Complications

Foreign ownership restrictions on land in Thailand mean that mortgages over land and buildings are typically granted by a Thai‑majority entity. If the Thai shareholders are found to be nominees, the entity’s right to hold land may itself be challenged, potentially rendering the mortgage unenforceable. Lenders should obtain title searches and land office records as part of standard bank due diligence in Thailand, and should require legal opinions on the borrower’s lawful capacity to hold land.

Enforcement Practicalities and Court or Insolvency Risk

Thai courts have the power to set aside fraudulent transactions and to investigate the true ownership of shares and assets. In insolvency proceedings, a trustee in bankruptcy may challenge the validity of security granted by an entity operating in breach of the FBA. The likely practical effect of the 2026 reforms will be an increase in contested security enforcement proceedings, particularly where nominee allegations are raised as a defence by borrowers or guarantors seeking to delay or defeat enforcement.

Cross‑Border Financing Structures and BOI / Treaty Routes

Despite the tightened restrictions, several legitimate pathways remain available for structuring cross‑border financing in Thailand. Lenders must understand each route’s requirements and limitations to protect their credit position.

BOI Financing Privileges, What Lenders Should Verify

The Board of Investment has extended promotional privileges that allow BOI‑promoted companies to engage in activities that would otherwise be restricted under the FBA, including in certain cases the ability to borrow in foreign currency and to remit funds abroad. Lenders considering BOI financing in Thailand should verify the scope of the promotion certificate, confirm that the borrower’s current activities fall within the promoted category, and require annual compliance certifications. A BOI‑promoted entity that diversifies outside its promoted scope may lose its exemption, and the lender’s security package with it.

Treaty Protection and ISDS Considerations

Thailand is party to numerous bilateral investment treaties that provide protections against expropriation and discriminatory treatment of foreign investors. For lenders relying on treaty routes for foreign ownership of Thai entities, it is essential to obtain a legal opinion confirming that the specific treaty in question covers the investor’s nationality, the type of investment (equity, debt or both), and the protections available (including investor‑state dispute settlement). Treaty protections do not automatically extend to lenders, they typically protect the investor, not its creditors, so lenders should structure their security to benefit from the investor’s treaty rights where possible.

Offshore Versus Onshore Guarantee Trade‑Offs

Where nominee shareholder risk is elevated, lenders should consider requiring offshore guarantees from the foreign parent or affiliate, in addition to or instead of onshore Thai security. Some international banks use a domestic guarantee and foreign loan structure, the Thai entity provides a guarantee to a Thai branch bank, which then extends the loan from its offshore books, to mitigate onshore enforcement risk. This approach has limits: the Thai guarantee may still be challenged if the guarantor’s legal status is disputed, and Bank of Thailand regulations on foreign exchange transactions must be observed. Nonetheless, diversifying the security package across jurisdictions remains a prudent risk‑management strategy for any institution engaged in lending to foreign companies in Thailand.

Enforcement Planning, A Realistic Recovery Playbook for Lenders

When a Thai borrower defaults and FBA‑related complications are present, lenders need a clear enforcement plan that accounts for the new regulatory landscape.

When to Involve Local Counsel and Authorities

Engage experienced Thai litigation counsel at the first sign of default, not after negotiations have stalled. Local counsel should advise on the viability of security enforcement given the borrower’s FBA status, the likelihood of nominee defences being raised, and the estimated timeline and cost of court proceedings. In cases where nominee arrangements are suspected, lenders may also consider filing a complaint with the DBD, which has the authority to investigate and impose administrative penalties. A concurrent DBD investigation can create leverage in enforcement negotiations, though it may also complicate and delay court proceedings.

Interim Protective Orders and Injunctions

Thai courts can issue interim protective orders to preserve assets pending final judgment, including orders freezing share transfers, blocking dividend payments, and restraining directors from dissipating company assets. Lenders should prepare applications for such orders in advance of filing the main enforcement action, and should be ready to demonstrate that there is a genuine risk of asset dissipation. Cross‑border enforcement of Thai judgments remains challenging; lenders with exposure in multiple jurisdictions should coordinate enforcement strategy across all relevant courts simultaneously.

Checklist for Bank Legal Teams, Redlines and Sample Clause Bank

The following redlines and sample clauses are designed for immediate insertion into facility agreements for loans to Thai borrowers with foreign ownership. Bank legal teams should adapt each clause to the specific transaction and take local counsel advice before finalising.

• Nominee warranty clause. See the sample ownership and nominee warranty above, include in representations and warranties section of the facility agreement.
• Anti‑nominee covenant. “The Borrower shall not permit any person to hold shares in the Borrower as nominee, agent or trustee for any Foreign Person, and shall procure that no such arrangement is entered into during the term of this Agreement.”
• FBA compliance covenant. “The Borrower shall at all times comply with all requirements of the Foreign Business Act B.E. 2542 (as amended) and shall promptly notify the Lender of any change in the classification of its business activities under the FBA lists.”
• BOI compliance covenant. “Where the Borrower relies on BOI promotion for exemption from FBA restrictions, the Borrower shall maintain compliance with all BOI promotion conditions and shall provide the Lender with copies of all annual compliance filings and any correspondence with the BOI.”
• Enhanced MAC clause. “Any change in law, regulation, administrative order or government policy that materially and adversely affects the ability of the Borrower to lawfully conduct its principal business activity in Thailand shall constitute a Material Adverse Change.”
• DBD investigation event of default. “It shall be an Event of Default if the DBD commences any investigation, issues any order, or takes any enforcement action against the Borrower or any of its shareholders in connection with nominee shareholding or any breach of the FBA.”
• Drawdown condition, legal opinion. “No Utilisation shall be made unless the Lender has received a legal opinion from Thai counsel (in form and substance satisfactory to the Lender) confirming the Borrower’s compliance with the FBA as at the Utilisation Date.”
• Security substitution right. “If any security interest granted under this Agreement becomes or is likely to become unenforceable as a result of any FBA‑related challenge, the Borrower shall promptly provide substitute security of equivalent value and quality, acceptable to the Lender.”
