Market context
Indonesia in the global coal & nickel trade
Indonesia is the world's largest thermal-coal exporter and the dominant force in nickel. Where the country sits in each market, and why it matters.

Two of Indonesia’s biggest export earners come out of the ground: thermal coal and nickel. In both the country is not just a participant but a price-setter, and the policies it chooses ripple through global markets. Understanding where Indonesia sits explains why a rule change in Jakarta can move a benchmark in Rotterdam or a battery contract in Seoul.
Coal: the world’s largest exporter
Indonesia is the biggest exporter of thermal coal, the grade burned for power. Its advantage is geography and geology: shallow, low-cost seams in Kalimantan and Sumatra sit close to the coasts of its largest customers across Asia. The coal tends to be lower in calorific value than Australian product, so it competes on price and proximity rather than energy content.
Where the coal goes
Export demand = China + India + ASEAN power growth
- China
- swing buyer; import policy moves the seaborne price
- India
- structural growth in coal-fired generation
- ASEAN
- Vietnam, the Philippines, and others adding capacity
Because Indonesia supplies the marginal ton for much of Asia, its export volume and domestic-supply rules help set the seaborne thermal-coal price.
That scale is also a vulnerability. When a major buyer tightens import quotas or builds out renewables, Indonesian volumes feel it first. The Domestic Market Obligation (covered in its own guide) adds a second pull, diverting tons to local power stations and away from the export market.
Nickel: from ore export to processed metal
Indonesia holds the largest nickel reserves in the world, and over the last decade it has reshaped the entire market. The pivot was policy: an export ban on raw nickel ore, designed to force processing onshore rather than shipping unrefined rock abroad.
- Before
Raw ore exported
Low-value unprocessed nickel ore shipped abroad for refining elsewhere.
- Ore-export ban
Processing forced onshore
Miners and partners must build smelters in Indonesia to add value at home.
- Now
Smelter and battery hub
Nickel pig iron, ferronickel, and battery-grade chemicals produced domestically.
The result is a wave of smelter investment and a growing share of the world’s processed nickel flowing from Indonesia, into both stainless steel and the electric-vehicle battery supply chain. The same policy that lifted volumes has periodically pressured prices, because the new capacity added supply faster than demand absorbed it.
Why it matters to an investor
For a coal name, the global lens is about demand durability: who is still buying, and for how long. For a nickel name, it is about where in the chain the company sits, raw ore, smelting, or refined battery material, because the margin and the policy exposure differ sharply at each step. Read an Indonesian miner against the export market it serves, not the domestic economy alone.
Indonesia does not just supply these markets. In coal and nickel alike, it helps set the price.
