Bangkok will clear its BTS Green Line obligations by the end of October 2025, while also planning a BTS Green Line fare restructure that could set a 65 baht maximum.
Bangkok has confirmed that it will repay 32 billion baht in debt to the BTS operator by the end of October 2025. The sum covers unpaid operation and maintenance fees for the BTS Green Line and closes a long-running dispute with Bangkok Mass Transit System PCL (BTSC).
Debt repayment plan
Governor Chadchart Sittipunt said the payment will not damage the city’s finances. He said the money will come from budget reserves that are not tied to other obligations.
After the repayment, Bangkok Metropolitan Administration (BMA) will still hold between 5 and 6 billion baht in reserves. Chadchart said the city manages its budget carefully and follows a value-for-money approach.
Delaying payment would only add costs. Under a court ruling, interest is charged at MLR +1, which is higher than the return from bank deposits. For that reason, the city says immediate repayment is the most sensible option.
Why the dispute matters
The move ends a legal conflict that had stretched on for years. BTSC, the operator of BTS, had repeatedly demanded payment of the overdue amount. The issue gained greater weight after an administrative court ordered the city to settle the debt in full.
For the city, the repayment is not only a legal decision but also a financial one. Bangkok says it wants to avoid letting interest accumulate further while restoring certainty around the Green Line’s costs.
Fare reform on the Green Line
At the same time, Bangkok plans to restructure fares on the BTS Green Line. The current system leaves BMA paying about 8 billion baht a year in operating costs, while ticket revenue is only around 2 billion baht.
The city says that gap forces public subsidy and is unfair to residents who do not use BTS services. The proposed tariff model is meant to better reflect real operating costs and make the system more transparent.
The maximum fare under the proposal would be 65 baht. Short trips in central Bangkok would be cheaper, while longer journeys, such as trips to the suburbs, could cost more.
What to watch next
For passengers, the main question is how the new fare structure will be applied in practice. Bangkok says the model should be realistic and beneficial for the wider public, but the final details will determine who pays more and who pays less.
For observers of urban transport, the case shows how a major city tries to balance debt repayment, subsidy pressure and fare policy at the same time. The outcome will shape how the BTS Green Line is funded in the next phase.
