Indonesia: How One Country Took Over Global Nickel Supply
No single country has dominated a major commodity market the way Indonesia has come to dominate nickel in the past decade. Understanding how this happened, what sustains it, and what could disrupt it is the single most important analytical question in nickel investing.
The ore export ban: one policy decision that changed everything
Indonesia's government banned raw laterite nickel ore exports in January 2020 (a more permanent version of a ban first attempted in 2014 before being reversed). The policy rationale: force downstream processing investment inside Indonesia rather than exporting raw ore value to China. The result exceeded all expectations. Chinese stainless steel companies — led by Tsingshan — poured tens of billions of dollars into RKEF smelter complexes at Morowali Industrial Park (IMIP) and Weda Bay Industrial Park (IWIP). Within five years, Indonesia went from exporting ore to China to exporting processed NPI and ferronickel at scale.
Between 2017 and 2024, Indonesian nickel output grew by approximately 680% — from roughly 230,000 tonnes Ni content to 1,800,000 tonnes. No other single-country supply shift has had a comparable effect on a major commodity market in the same period. This supply surge is the primary reason LME nickel is at $15,500/t rather than the $25,000–$30,000/t that pre-2020 demand models projected.

RKAB permits: Indonesia's throttle valve on world supply
Every Indonesian nickel mine must have an approved annual RKAB (Rencana Kerja dan Anggaran Biaya) work plan. The government uses these approvals to control total output. In 2025, RKAB quotas were tightened below 2024 levels as part of Indonesia's strategy to protect the economics of its own HPAL plants (which need higher nickel prices than RKEF to be profitable). This is the single most important geopolitical variable in the global nickel market. Any meaningful tightening of RKAB approvals would materially change the surplus timeline. Any loosening would extend it.
For investors, RKAB is both a risk and an opportunity. It is a risk because it represents arbitrary policy interference in supply. It is an opportunity because if Indonesia decides — as it has signalled it may — to restrain supply growth to ensure HPAL investment returns, the nickel price recovery arrives earlier than the base case projects.
⚙RKAB: the variable most analysts underweight
Most nickel supply models treat Indonesian output as a smooth extrapolation of past growth. RKAB quotas can step-change that trajectory in either direction within a single quarter. Watch for Indonesian MEMR announcements, particularly around October–November when quotas for the following year are typically set. A 10% reduction in RKAB quotas would remove approximately 180kt of supply — more than the current annual surplus.
The HPAL revolution: Indonesia going Class 1
The next chapter of Indonesia's nickel dominance is HPAL. HPAL (High-Pressure Acid Leach) converts limonite laterite ore — which can only produce Class 2 NPI via RKEF — into MHP (Mixed Hydroxide Precipitate), a Class 1 battery-grade intermediate product. Indonesia has approximately 40 HPAL plants announced or under construction, of which approximately 8 are operating at time of writing. Key operators include Huafei, Harita, and QMB (a JV involving CATL and Zhejiang Huayou). When these plants ramp to full capacity, Indonesia becomes the dominant global source of both Class 2 and Class 1 nickel — directly supplying the EV battery supply chain from the world's largest laterite resource base.
This transformation has profound implications for Class 1 pricing: if Indonesia's HPAL plants produce at lower AISC than sulphide-based Class 1 producers (the economic test is approximately $10,000–$14,000/t HPAL vs $9,000–$18,000/t sulphide, so HPAL is cheaper for lower-cost operators), the Class 1 premium may permanently compress as Indonesian laterite replaces sulphide as the marginal Class 1 producer.
RKEF — Class 2 NPI
Processes saprolite laterite. Output: NPI 8–12% Ni. Used in stainless steel. Cannot enter EV battery supply chain.
AISC: ~$4,000–$7,000/t · Profitable at $15,500 LME
HPAL — Class 1 MHP
Processes limonite laterite. Output: MHP 35%+ Ni+Co. Battery-grade Class 1. Feeds NMC cathode precursor supply chain.
AISC: ~$10,000–$14,000/t · Marginal at $15,500 LME
New Caledonia's crisis: the cost curve in action
New Caledonia is a French territory with substantial laterite nickel resources but AISC of $14,000–$20,000/t — among the most expensive nickel in the world. By 2024–2025, three major operations had suspended or entered administration: SLN (Société Le Nickel), Koniambo Nickel SAS, and Prony Resources. Political unrest (independence-related violence and mine blockades) compounded the economic pressure from low prices. The closures collectively removed approximately 120–150kt of annual supply — the largest single-country production loss of the current price cycle. New Caledonian production is unlikely to return at scale unless LME prices recover sustainably above $18,000/t.
⚠New Caledonia: 120–150kt of permanent supply reduction
Unlike cyclical curtailments that restart when prices recover, New Caledonia's closures involve shuttered plants, redundant workforces, and deteriorating infrastructure. Koniambo's restart would require hundreds of millions in recommissioning capex — not viable below $18,000–$20,000/t. This supply loss is increasingly being treated by analysts as structural, not temporary — which meaningfully tightens the long-run supply model.
