Bangkok – The Office of Trade Competition Commission (OTCC) moved to halt the proposed sale of Tesco’s Thai and Malaysian retail outlets on Friday, putting a $10 billion transaction on hold. The decision surprised observers who had not been tracking the 2017 Trade Competition Act, a law that strengthened Thailand’s antitrust framework after years of limited enforcement. Until now, the auction for Tesco’s roughly 2,000 stores in the two countries had progressed smoothly, with three domestic conglomerates remaining as the final bidders: Charoen Pokphand Group (CP Group), Central Group and TCC Group.
All three already operate extensive retail networks, and the sale was expected to fetch up to $10 billion. OTCC Chairman Sakon Varanyuwatana told reporters that the commission would examine any prospective purchase and warned that it has the authority to block a merger that could create a monopoly.
Under the 2017 Act, the regulator can impose fines of up to 0.5 percent of a transaction’s value for violations – a sum that would amount to $50 million on a $10 billion deal. Euromonitor data shows Tesco’s Thai operations account for about 28 percent of the nation’s supermarket, hypermarket and convenience‑store sales. Each of the three shortlisted buyers already controls a sizable share of the retail sector, meaning a combined entity would likely breach the 50 percent market‑share threshold set by the 2017 legislation.
CP Group, for example, runs Thailand’s 7‑Eleven master franchise, overseeing more than 12,000 convenience stores. Adding Tesco’s larger‑format outlets would give the group dominance across both convenience and big‑box formats.
Central Group’s portfolio includes department stores, electronics chains and food retailers, while TCC Group, led by billionaire Charoen Sirivadhanabhakdi, holds interests in breweries, hotels and its own retail assets. The 2017 Trade Competition Act requires parties to file a merger notification when a deal exceeds 1 billion baht (approximately $33 million) or when a buyer would hold at least 25 percent of a market already dominated by a few players. Tesco’s Thai business alone surpasses these thresholds, and the same applies to the three potential acquirers given their existing market positions.
With the OTCC’s intervention, the auction is now paused. The regulator will await the identification of a preferred bidder before conducting a formal review.
Possible outcomes include approval with conditions, outright rejection, or a requirement for divestitures to preserve competition. This is the first major test of the OTCC’s enhanced powers since the 2017 law replaced the weaker 1999 framework, which critics said allowed large corporations to operate with little oversight. The agency’s decisive action signals that Thailand’s antitrust watchdog is no longer a “paper tiger.” The impending decision will be watched closely by conglomerates across Southeast Asia, as it may set a precedent for future retail consolidations in the region.
As of now, the bidders and Tesco have remained silent, while the OTCC has made its stance clear. The countdown has begun, and the potential $50 million fine underscores the seriousness of the regulator’s review.
