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

Cambodia’s Ministry of Justice has launched a new platform on its official website to publish notices of forced sales issued by each municipal and provincial court of first instance. The platform’s stated purpose is to inform the public and facilitate greater participation in forced-sale auctions conducted in connection with court-ordered enforcement proceedings. How the Platform Works The platform publishes forced-sale notices from courts of first instance across Cambodia’s municipalities and provinces and includes a link where the public can view properties currently subject to forced sale. To participate in a forced-sale auction, individuals can download Khmer-language bidding application forms through links provided on the platform. The form typically requires the applicant’s name, sex, year of birth, identity card number and issue date, and address, together with details identifying the immovable property (including its ownership certificate number), the relevant enforcement case number and date, and the reference to the public auction or tender announcement issued by the court. Completed application forms must be submitted directly to the specific municipal or provincial court that issued the forced sale. For further inquiries about a particular forced sale, interested parties should likewise contact the relevant municipal or provincial court. Forced Sale of Immovable Property in Cambodia The publication of these notices relates to the forced sale procedure for immovable property under Cambodia’s Code of Civil Procedure (CPC). Unlike property seizure by a court, a forced sale is a compulsory execution proceeding—a subsequent enforcement step that arises only after an underlying dispute has been adjudicated and a debtor fails to pay the debt or outstanding amount due under a final and binding judgment or other enforceable title of execution. For the purposes of this procedure, the term “immovable property” under the CPC refers to land, registered buildings, jointly held shares of such property, registered

Thailand’s cabinet has approved a draft ministerial regulation introducing significant changes to the calculation of old-age pension and old-age gratuity benefits under the Social Security Fund. The reform would replace the current pension calculation method with a career average revalued earnings (CARE) model designed to better reflect an individual’s lifetime contributions while supporting the long-term financial sustainability of the Social Security Fund. The changes are also intended to improve fairness and align Thailand’s pension framework with international practices. Key proposed changes under the draft ministerial regulation are outlined below. CARE-Based Formula for Old-Age Pension Calculations Currently, old-age pensions are calculated based on the insured person’s average salary over the preceding 60 months. The proposed regulation would replace this approach with the CARE model, under which pension benefits will be calculated based on earnings throughout an individual’s entire working life. Historical earnings will be revalued to reflect their present value before the pension benefit is calculated. According to the Ministry of Labor, this change is intended to better align pension benefits with an individual’s lifetime contribution history and provide a fairer basis for calculating benefits. Pension Accrual Rate for Contributions Exceeding 180 Months Under the current rules, insured persons who contribute for more than 180 months receive an additional pension accrual of 1.5% for each completed 12-month contribution period, with any remaining months disregarded. The proposed regulation would instead calculate the additional accrual on a monthly basis at a rate of 0.125% of actual monthly contributions; this aims to make pension benefits more accurately reflect the actual duration of each individual’s contribution history. Transitional Protections for Insured Persons The draft regulation includes transitional protections for both existing pension recipients and those who will become eligible within five years of the CARE model taking effect. For existing recipients, the following protections

On July 8, 2026, Thailand enacted a new law significantly expanding the framework for government service delivery and licensing facilitation. The Facilitation of Licensing and Public Services Consideration Act B.E. 2569 (2026) (Facilitation Act 2026) replaces and expands the framework of governmental services under the Facilitation of Official Licensing Consideration Act B.E. 2558 (2015) (Facilitation Act 2015) and broadens its scope to cover public services, administrative processes, and public benefits. The Facilitation Act 2026 aims to modernize government services by promoting e-filing, reducing administrative burdens and repeated document requests, and improving predictability. For businesses, this should ease compliance and shorten approval timelines, subject to implementing regulations and agency readiness. Public Services Facilitation Scope The Facilitation Act 2015 applied mainly to permissions, registrations, and notifications required before conducting activities that require licenses, certificates, permits, approvals, or registrations. The Facilitation Act 2026 broadens this framework to include public services and other benefits, such as welfare, subsidies, and grants, provided to Thai citizens, expanding government agencies’ responsibilities beyond licensing facilitation into a wider administrative-service framework. It also introduces a broader definition of “government agency” to include central, regional, and local government bodies, state enterprises, public organizations, and other state entities. Licensing Changes The Facilitation Act 2026 introduces a “super license” (termed a “main license” under the act) that exempts the holder from obtaining multiple related or ancillary licenses issued by different government agencies. Obtaining a super license deems the licensee to have automatically obtained the related “sublicenses” required to conduct the relevant activities. The cabinet will designate eligible activities by royal decree. The act also introduces an expedited licensing option, allowing applicants to pay an additional fee to fast-track their applications in urgent cases. Expedited processing must not interfere with standard application timelines. The criteria, procedures, conditions, and fees for expedited licensing
