Thailand’s Competition Law and Regulations: Background and Outlook for 2023

Thailand has a robust legal framework for competition, with laws and regulations in place to prevent anticompetitive conduct and market concentration and to promote fair competition. However, as the business environment in the country continues to evolve, it is important for companies operating in Thailand to stay informed about the latest developments in competition laws and regulations.

Generally, Thailand’s competition regime is based on the Trade Competition Act B.E. 2560 (2017) (the TCA) and its implementing regulations, except for certain industries which are governed by sector-specific competition regulations. The TCA is designed to promote free and fair competition by suppressing anticompetitive behaviors.

In this article, we will examine what businesses can expect in the coming year, and what they need to be aware of in order to stay compliant.

A Maturing Regulatory Structure

The Trade Competition Commission of Thailand (TCCT) is the agency responsible for enforcing competition laws and regulations in Thailand. The TCCT has the authority to oversee the market structure, act to maintain competitiveness in various industries, investigate misconduct, and take action against companies that engage in anticompetitive practices, such as abuse of market dominance, cartels, and unfair trade practices. It also has discretionary power to consider applications for a merger of two or more businesses that may cause monopoly or market dominance.

While the TCA and the TCCT had limited success in the decades after the original TCA’s enactment in 1999, a new TCA in 2017 made several significant changes to the previous version of the law. The 2017 TCA guarantees the independence of the TCCT from political and business interventions. It also introduces administrative penalties for less-serious offenses, including non-hardcore cartels, unfair trade practices, and neglect of merger filing duties.

Since then, the TCCT has been more active in its issuance of subordinate regulations to optimize the functionality of TCA provisions. A number of business-specific guidelines adopted from time to time address competition concerns in certain business sectors, such as modern trade, franchises, and food delivery services. The TCCT has also issued rules that purchasers must follow when setting credit terms for SMEs (small and medium enterprises).

The level of enforcement has also escalated, evidenced by more than 60 cases determined and concluded during 2019–2021—mostly regarding merger filings and unfair trade practices. In recent years, the TCCT has had oversight of several high-profile mergers, issuing remedies and closely keeping track of the companies’ business conduct to ensure compliance with fair trade and competition requirements. The administrative office of the TCCT has also accomplished the first proactive investigation procedures involving unannounced inspections, commonly known in some jurisdictions as “dawn raids,” conducted at the accused’s premises to obtain useful evidence for cartel misconduct.

TCCT’s academic role has also been well recognized. The TCCT has conducted market studies of many emerging industries, such as e-commerce and marketplace platforms, to understand business practices and identify potential anticompetitive behaviors. The TCCT also acknowledges that the TCA should not stop evolving in today’s complex economy. In collaboration with the Thailand Development Research Institute, the TCCT studied whether and how to improve the TCA and its enforceability, resulting in the proposal of significant amendments to the TCA.

The regulatory structure of Thailand’s competition regime has matured a great deal in the past five years. This increased reliability is likely to continue in 2023 as the TCCT looks to deal with concerns about today’s market conditions.

TCCT and Emerging Issues

One of the key areas of focus for the TCCT in the coming year will be the digital economy. With the rapid growth of e-commerce and online platforms, the TCCT will be closely monitoring the growing market power of these operators to ensure that competition is fair and that consumers’ selection of goods and services is not manipulated. This is particularly important as the COVID-19 pandemic has accelerated the shift to what the Thai government has called the “platform economy.” Recognizing that some plaftform operators’ conduct and trade conditions could damage competitors and trade partners, or restrict consumers’ choices, the TCCT set out to develop a new set of regulations and strategies to address these competition concerns. In this regard, the TCCT may adopt new legislation modeled on the Digital Markets Act of the European Union to more efficiently tackle anticompetitive conduct by digital marketplaces and online gatekeepers.

One of the TCCT’s missions in the year ahead will be to revitalize its existing regulations. The TCCT is prepared to raise the threshold for determining whether a company is in a position of market dominance, in light of the country’s economic growth and heightened inflation. Another area of focus is amendments to enhance the clarity of merger control rules and to extend the scope of control to certain types of mergers such as a full-function joint ventures, which are not yet clearly regulated under the current rules.

In terms of enforcement mechanisms, the TCCT is studying the possibility of implementing a leniency program that would grant immunity to whistleblowers who expose collusive arrangements. This leniency program would be a highly useful instrument for the TCCT in detecting cartels, similar to the success of leniency policies in exposing collusion in the United States, the European Union, Japan, and other jurisdictions.

Conclusion

Overall, businesses operating in Thailand can expect the TCCT to continue its efforts to promote fair competition and to intensify the level of enforcement in the coming year, with a particular focus on the digital economy and merger control. Companies should stay informed about the latest developments in competition laws and regulations and seek legal advice when necessary to ensure compliance. While competition is just one of the many areas of compliance that businesses have to uphold, enlisting outside assistance in maintaining a healthy and resilient presence in the market can greatly ease the burden.

On July 7, 2026, the Trade Competition Commission of Thailand (TCCT) issued a press release announcing the establishment of two new subcommittees designed to intensify oversight of digital platforms and modern trade businesses. The formation of the digital platform subcommittee marks a significant escalation in competition enforcement following the TCCT’s Guidelines on Multi-Sided Platforms and E-Commerce Businesses, which took effect on March 25, 2026. Platform operators, sellers, and related service providers should expect heightened regulatory scrutiny and potential investigations into practices already flagged under the March guidelines. Two Dedicated Enforcement Bodies The first new body is the digital platform subcommittee—formally the Subcommittee on Supervision, Monitoring, and Prevention of Trade Conduct in Digital Platform Business. It is tasked with driving intensive oversight of digital platform businesses. It will coordinate with government agencies, the private sector, business operators, and other relevant stakeholders to supervise and prevent trade conduct that may affect competition, and to promote free and fair competition in the digital platform sector. The subcommittee will be composed of TCCT members and representatives from the Department of Internal Trade. The second body—the Subcommittee on Determining Guidelines and Action Plans Concerning Competition Conditions in Modern Wholesale and Retail Business—will study, analyze, and monitor market structure in modern wholesale and retail businesses, compile databases to analyze retail business concentration, assess impacts on small-scale operators, and propose supervisory measures for the retail sector. TCCT members will serve on the subcommittee alongside experts from government and private organizations, including the Office of Industrial Economics, the Office of Small and Medium Enterprises Promotion, the Thai SME Federation, and the Thai SME Council. Operational Impact for Industry Participants These subcommittees provide the TCCT with a focused mechanism to investigate various trade practices deemed unfair, and the TCCT has authority under the Trade Competition Act to issue cease-and-desist

Thailand’s Board of Investment (BOI) has significantly revised its post-approval compliance framework for projects that receive investment promotion incentives, replacing the previous semiannual reporting system for project progress with a new quarterly reporting regime. The initial report is due by July 30, 2026, covering the second-quarter reporting period of April to June 2026. The new requirements—implemented through BOI Announcement No. 8/2569 and Office of the BOI Notification No. Por. 8/2569, both of which became effective on March 30, 2026—apply both to newly promoted projects and to existing promoted projects that remain in the implementation stage. Background Under the previous reporting framework, BOI-promoted companies that had not yet commenced full operations were generally required to submit reports on project progress to the BOI twice a year (February and July) through the BOI’s e-Monitoring system. By adopting a quarterly reporting regime, the BOI seeks to strengthen monitoring and evaluation of investment progress and project implementation. Reporting Requirements Under the new regulations, BOI-promoted companies must submit project progress reports on a quarterly basis during the implementation phase of a promoted project. The reporting periods and submission deadlines are: Q1 (January–March): April 30 Q2 (April–June): July 30 Q3 (July–September): October 30 Q4 (October–December): January 30 of the following year The quarterly reporting obligation runs from the date the BOI promotion certificate is issued until the BOI grants approval for commencement of full operations. For newly promoted projects, no quarterly report is required for the quarter in which the BOI promotion certificate is issued—the first reporting obligation arises in the immediately following reporting period. All project progress reports must be submitted electronically through the BOI’s e-Monitoring system. The existing annual reporting requirement also remains in effect, requiring promoted companies to submit an annual operating results report through the e-Monitoring system by July 31 of

On April 28, 2026, the Central Bank of Myanmar (CBM) issued Notification No. 18/2026 introducing the new Foreign Remittance Business Regulations. The new regulations apply to companies intending to operate foreign remittance businesses in Myanmar that are not licensed banks, non-bank financial institutions, or other financial institutions. The regulations supersede and replace the previous regulatory framework governing foreign remittance businesses under CBM Notification No. 21/2019. While the overall structure remains familiar, the new regulations introduce more detailed requirements for licensing, operations, reporting, and compliance, with a stronger focus on transparency and regulatory oversight. Broader Licensing Requirements Under the new regulations, applicants must submit detailed business plans describing the use of information technology and mobile platforms, along with clear plans for handling remittances from workers abroad and resolving customer complaints. Financial Thresholds and Reporting Requirements The baseline financial thresholds remain unchanged. Licensees must maintain a security deposit of MMK 100 million in an escrow account, along with a separate revolving fund dedicated solely to remittance operations. The new regulations introduce more structured reporting obligations. Licensees are now required to submit daily remittance transaction data by the next business day before noon, in addition to monthly and periodic reporting requirements. Foreign bank account statements must also be submitted regularly, and licensees must provide updates on business operations every six months. Strengthened AML and CFT Framework The new regulations place a greater emphasis on anti-money laundering (AML) and counter financing of terrorism (CFT), with tighter controls over management changes. Any changes in shareholding, share transfers, or the appointment of key management personnel such as the managing director require prior approval from the CBM. Licensing Fees and Validity The new regulations increase licensing costs, while maintaining the same validity period of three years. The new regulations provide more detailed grounds for suspension and
