Mass Transit Pricing and Fare Caps in Bangkok

This paper analyzes the political and economic implications of the Thai government’s plan to cap mass transit train fares in Bangkok at 20 baht for citizens, expanding on previous populist initiatives by the Pheu Thai party. Driven by stalled major economic policies, the government turned to municipal transit issues, seeking a simple public benefit that appeals to lower-income voters. While Bangkok’s current fares are exceptionally high relative to the minimum wage, hindering worker mobility and contributing to economic inefficiency, the paper argues that a system-wide cap is unlikely to lead to stable revenues or allow for crucial transit expansion. The author suggests that a mixed approach, reducing costs for key interchange lines while potentially raising minimum fares, could better ensure the financial sustainability and comprehensive development of the transit system.
