Indonesia January-September coal export volume down 10.58% annually, government data shows

What happened

Indonesia exported 255.05 million metric tons of coal from January to September, down 10.58% from the same period last year, statistics bureau data showed. Those shipments were worth $18.81 billion, 4.86% higher than the same period a year earlier.

Confirmed

Global impact / market context

Smaller coal volumes from a major global supplier can tighten seaborne coal supply, which means the amount of coal shipped by sea. Higher value per ton means exporters earn more revenue per shipment even as total tons fall, supporting sales value for producers and the government.

Analyst inference

The figures come from customs reports, while the energy ministry uses mining company reports, so the two datasets can differ. That split matters because investors tracking Indonesian coal producers face conflicting official numbers, making the export trend harder to read confidently.

Analyst inference

What to watch

1. Watch upcoming monthly customs export figures for October onward to see whether the 10.58% year-on-year volume decline continues or stabilizes. Confirmed
2. Compare the customs figures with Energy and Mineral Resources Ministry data, which use mining company reports, to check whether the two official series confirm the same volume trend. Proposed
3. Track whether export value keeps rising while volumes fall, since that combination indicates higher prices per ton, which means the amount received for each ton sold. Analyst inference
