The Bangkok Metropolitan Administration (BMA) has vowed to resolve its 30-billion-baht debt tied to the Green Line electric railway within the next 30 days.
Officials confirmed the BMA currently owes Bangkok Mass Transit System PCL (BTSC) over 31.5 billion baht in unpaid operations and maintenance fees.
The move follows the release of a special committee report that detailed the full extent of the debt, which covers both principal and interest payments.
According to Kanoknuch Klinsung, a Bangkok Council member serving on the committee, the debt includes 12.2 billion baht from a lawsuit filed between 2021 and 2022, as well as 17.1 billion baht from the period between November 2022 and December 2024.
She added that a further 8.3 billion baht is projected to be added in 2025.
Negotiations between the BMA, represented by its state enterprise, Krungthep Thanakom, and BTSC have stalled in recent months.
The BMA has proposed making partial repayments on the condition that BTSC unconditionally withdraws its legal case. Should talks fail, the dispute would proceed to the Central Administrative Court.
BTSC has rejected the proposal, instead demanding full repayment by October 2025 and warning that overdue payments would accrue interest at a rate of MLR+1%.
The committee has since urged the BMA to accelerate negotiations, warning that delays would result in growing interest charges and possible fiscal harm to the city.
Bangkok Governor Chadchart Sittipunt said he has acknowledged the report and that officials are currently reviewing the city’s financial reserves to determine whether sufficient funds are available.
He confirmed that all options would be assessed and that a settlement plan will be finalised within 30 days.
