The supply contraction stems from a restrictive government stance on production quotas, which has left international buyers wary of committing to long-term deals. While authorities attempted to adjust quotas mid-year, the initial deep cuts created a lingering atmosphere of instability. This hesitation is compounded by the effects of a strong El Niño, which has depleted river levels and crippled the barge transport network essential for moving coal to export terminals.

Energy traders are already adjusting their outlooks to reflect these bottlenecks. Matthew Boyle, head of research at Ashon International DMCC, noted that his firm expects its Indonesian coal sales to halve to 2 million tons this year. The International Energy Agency projects total Indonesian output will fall by 1.5% in 2026, citing a reduced production target of 641 million tons. Ongoing debates regarding export taxes, revenue-sharing models, and a potential move toward centralizing exports under a state-controlled entity continue to cloud the sector's trajectory.
