The State Railway of Thailand (SRT) is at a crucial juncture regarding the High-Speed Rail Linking Three Airports Project (Don Mueang–Suvarnabhumi–U-Tapao), after a recent tripartite meeting involving Asia Era One Co., Ltd. (the private concessionaire) and the Eastern Economic Corridor Office (EECO). According to SRT Governor Anan Phonimdang, only two options remain: proceed via significant contract amendments or initiate contract termination processes.
Asia Era One has proposed negotiations for possible contract termination, citing the drastically changed investment environment stemming from the impacts of the COVID-19 pandemic and regional conflicts. These events have affected the original economic assumptions underlying the 2019 contract, raising concerns over investment returns and access to funding.
There are three primary ways the contract could conclude: 1) natural expiry after 50 years of operation, 2) failure to fulfill pre-conditions such as land handover or obtaining Board of Investment (BOI) investment privileges, or 3) early termination due to force majeure, contractual breaches, or for public benefit. Force majeure clauses specifically cover uncontrollable events like pandemics and war, but do not automatically include financial viability or funding problems, which require legal assessment.
SRT is currently awaiting an official proposal from Asia Era One outlining the specific grounds for contract termination. Both parties retain the right to seek compensation, and if the contract ends, detailed negotiations will determine accountability for any damages.
Due to declining returns—reported as low as 5%—and rising interest rates, the private partner remains exposed to considerable financial risk. With lenders urging a project review, SRT is seeking pathways to address these challenges. Any recommendation for termination or amendment will go through several committees before final EECO approval.
If the project is re-tendered after contract cancellation, BTS Group Holdings PCL (SET: BTS) is open to participating, provided the revised tender terms reflect current economic realities and support more balanced investment conditions. The previous terms, described as challenging, may need significant revision for new entrants to consider bidding.
Bualuang Securities noted that a BTS-led bid would be a strategic fit, given BTS’s investment in the U-Tapao Aviation City. Control of the rail link would allow BTS to integrate air and rail transport, creating a comprehensive transport and commercial hub. U-Tapao International Aviation Co., Ltd., where BTS holds a 40% stake, recently boosted its capital to THB 20 billion in preparation for expanding operations in the Eastern Airport City.
