How Nickel's Supply Chain Moved to Indonesia in a Decade
Indonesia went from a minor nickel supplier to the dominant one after banning raw ore exports and pulling in Chinese processing investment.
Nickel’s supply chain concentration is unusual among the materials on this site because it is recent and traceable to a specific, documented policy decision, not purely a consequence of where the geology happens to sit.
The export ban that reshaped the industry
In 2020, Indonesia banned exports of unprocessed nickel ore, a deliberate policy choice intended to force processing investment onshore rather than let the raw material leave the country unrefined. The strategy worked in the sense the government intended: it triggered a wave of smelter and HPAL plant construction inside Indonesia, much of it financed and built through partnerships with Chinese companies bringing capital and processing technology, covered in more depth on this material’s financing page. Indonesia’s share of global nickel production grew dramatically over the following years as a direct result, a real, deliberate industrial policy outcome, not an emergent market trend.
What this concentrates, specifically
The result is a nickel supply chain where both mining and, increasingly, processing sit in one country, with Chinese firms holding substantial ownership and technology stakes in the processing plants that actually convert Indonesian laterite ore into battery-grade nickel. This is a different concentration structure from cobalt’s split between DRC mining and Chinese refining: here mining and much of the processing have converged in the same place, with the ownership and capital ties running through China regardless.
