The Bank of Thailand (BOT) is seeking public comment on proposed amendments that would significantly expand know-your-customer (KYC) and customer due diligence (CDD) requirements for cash-related transactions at financial institutions (FIs) and specialized financial institutions (SFIs). Released on August 5, 2026, the proposed regulation would supersede BOT Notification No. 16/2569, which focused primarily on cash withdrawal transactions. The public comment period is open through September 3, 2026. The amendments reflect concerns that FIs and SFIs may be used to facilitate the movement, concealment, and conversion of criminal proceeds, potentially damaging institutional operations and public confidence in the financial system. Expanded Scope of Covered Transactions The most significant change is the broadening of the definition of “cash-related transactions.” Previously, the regulation covered only cash withdrawals and uncrossed check withdrawals. The amended regulation extends coverage to include: Cash deposits, check deposits, or receipt of funds from the public not in the form of deposit accounts; Thai baht (THB) banknote exchange (different denominations); Receipt of cash for issuing checks and drafts; and Purchase, sale, or exchange of foreign banknotes. Mandatory Identity Verification and Risk Management For all cash-related transactions, FIs and SFIs must require customers, or authorized or delegated persons, to present identification or verify their identity before every transaction, including one-time (walk-in) transactions. Specific identification requirements vary by transaction type, customer nationality, and channel (branch vs. electronic). FIs and SFIs must also establish comprehensive risk management processes and procedures for cash-related transactions. These requirements include identifying customers or authorized representatives in accordance with transaction-specific verification standards, analyzing customer behavior, implementing risk-management measures proportionate to the customer’s risk profile, and recording abnormal behavior in relevant systems. The BOT also encourages institutions to proactively guide customers toward transaction channels that offer greater traceability than cash. For corporate customers in high-risk business sectors—including foreign

Tilleke & Gibbins has contributed the Thailand and Vietnam chapters to Investigations in Southeast Asia, a comprehensive guide published by Drew Network Asia (DNA). The resource provides a practical overview of anticorruption laws, corporate investigations, and compliance frameworks across six key Southeast Asian jurisdictions. Designed for in-house counsel, compliance officers, and risk management professionals, the guide offers actionable insights for navigating complex cross-border regulatory challenges and establishing effective, regionally coordinated compliance and investigation strategies. The guide begins with a regional perspective on enforcement trends and cross-border cooperation initiatives. Jurisdiction-specific chapters follow a standardized structure—covering primary corruption offenses, enforcement authorities, corporate liability, investigation procedures and dawn raids, whistleblower protections, and recommended compliance measures. In addition to country-by-country analysis, the publication highlights best practices for conducting internal investigations, managing digital evidence, and handling parallel proceedings involving multiple regional or international regulators. The guide serves as a practical reference for organizations operating in Southeast Asia. Because legal and regulatory risks depend on specific industry sectors and operational contexts, readers seeking tailored advice are encouraged to contact the authors listed in each chapter.

Thailand’s Anti-Corruption Cooperation Committee has issued a major update to the anticorruption standards required for private entities engaging in high-value state projects. The update, titled “Announcement re: Procurement Limits and Minimum Anticorruption Standards (No. 2),” replaces and amends key provisions of the original announcement dated September 25, 2024. Published in the Government Gazette on April 10, 2026, the new rules take effect on May 10, 2026, and apply to projects valued at more than THB 300 million (approximately USD 9.3 million). The key amendments to the anticorruption standards are detailed below. Expanded Definition of Conflict of Interest The 2026 regulation significantly broadens the scope of what constitutes a conflict of interest compared to the 2024 version, which focused primarily on basic kinship and business ties. Under the new rules, a conflict of interest includes using one’s position or authority to seek benefits for oneself, a group, close associates, or business, including through business relationships, kinship ties, or relationships with spouses or individuals living together as partners without marriage registration. The 2026 announcement also introduces specific examples that were largely absent from the 2024 text, such as holding shares in similar businesses that submit proposals for the same project, or submitting proposals for projects in which a relative, spouse, or unregistered partner is an “involved party” in that procurement. Continuous Compliance: The “Final Payment” Rule Under the 2024 rules, the coverage period for anticorruption policies was less strictly defined. The new regulation mandates a continuous timeline: policies or certifications must remain effective from the date of bid submission until the contractor receives the final payment installment under the contract. If a certification or policy is set to expire before the final payment, the contractor must submit a new self-audit form and supporting evidence to the state agency before the original

Doing business in Thailand means operating under a strict regulatory framework. From time to time, companies may receive unexpected administrative orders from government authorities that restrict their operations, impose new compliance obligations, or levy fines and penalties. When this happens, a business may challenge the order under Thailand’s administrative law system. The primary concern in pursuing administrative litigation is timing, as strict statutory deadlines apply and missing them can permanently affect a company’s rights. First Step: Administrative Appeal Many companies assume the first step is to immediately bring the matter before the Administrative Court to seek revocation or suspension of the order. Some even attempt to request an interim injunction to stop the order from taking effect. However, Thai law generally requires that the company first challenge the order through an administrative appeal with the same agency that issued it. Only after this process is complete can the matter be taken to court. Seeking an interim injunction at this stage is also not possible. This is because Thai law does not allow a standalone application for an interim injunction; an injunction can only be requested together with the underlying complaint filed with the Administrative Court. Since a court complaint cannot be filed until the administrative appeal process has been exhausted, an injunction is usually not available at the early stage. What Are the Timeframes for Administrative Appeal? Thailand applies a two-stage administrative appeal process. The appeal must first be submitted to the same authority that issued the order, which will review its own decision. If that authority affirms its decision, the appeal is then escalated to the relevant higher authority for further review. In most cases, both stages must be completed before a company is allowed to proceed to court. The timeframe for filing an administrative appeal is very
