Policy-driven supply constraints weigh on Indonesia’s coal exports

Indonesia’s coal exports have started Cal’26 on the back foot, with shipments so far at ~70Mt, down -31% YoY from 101Mt in the same Cal’25 period.

Indonesia coal exports Cal 2026 weekly loadings in Mt per week versus 2024 and 2025, highlighting reduced volumes amid policy pressure despite short-term weekly rebound within the five-year range.

Despite mild prices, the shortfall looks primarily policy-led rather than cyclical or conjunctural.

Still, some miners have reportedly paused spot exports after receiving proposals to cut Cal’26 production quotas by 40–70% vs ‘25. With allocations still under negotiation and details unclear, cargoes appear to be withheld, which has tightened near-term seaborne availability even as buyer demand softens, despite objections from the Indonesia Coal Mining Association.
