Indonesia nickel

What it is

Indonesia nickel refers to the country's dominant position in global nickel supply, built on the world's largest reserves of laterite nickel ore concentrated in Sulawesi, Maluku, and Papua provinces. Laterite deposits fall into two types: limonite (low-grade ore processed via High Pressure Acid Leaching, or HPAL, to yield battery-grade mixed hydroxide precipitate) and saprolite (higher-grade ore smelted into nickel pig iron for stainless steel). Indonesia's policy since January 2020 requires all ore to pass through domestic processing before export. The Indonesian government controls output volumes through the RKAB system (Rencana Kerja dan Anggaran Biaya, Work Plan and Budget), annual mining-work-plan certificates setting hard tonnage ceilings per concession. The RKAB ceiling means Jakarta, not the market, governs global nickel supply.

History

Commercial nickel mining in Indonesia began in 1968 when PT International Nickel Indonesia (now Vale Indonesia) started operations at Sorowako, South Sulawesi. President Joko Widodo banned unprocessed mineral exports in 2014, then reinstated the definitive raw-ore export ban on January 1, 2020, two years ahead of the original 2022 deadline. The 2020 ban triggered large-scale Chinese investment in smelting, most visibly at the Indonesia Morowali Industrial Park in Central Sulawesi, funded primarily by Tsingshan Holding Group. Indonesia's mined nickel output rose from approximately 358,000 tonnes in 2017 to 2.2 million tonnes in 2023, making it the world's largest producer. By 2024, Indonesia accounted for roughly 60% of global nickel mine production, according to USGS estimates.

Current state

As of mid-2026, Indonesia's Ministry of Energy and Mineral Resources set the 2026 RKAB ceiling at 270 million wet metric tonnes, down from approximately 375 million tonnes approved in 2025. That ceiling was reached by late June 2026, per Mysteel market reporting on June 24, leaving the mid-year supplementary application window as the only potential relief for smelters short on ore feedstock. The supply squeeze is documented in the quota-ceiling node. Sulphuric acid costs in HPAL processing reached US$1,000 per tonne by early 2026, up from around US$150 per tonne two years prior, compressing plant margins as described in the HPAL crisis node. The International Nickel Study Group projected a 2026 market deficit of 32,000 tonnes, reversing a 2025 surplus of 283,000 tonnes. The London Metal Exchange nickel price rallied 37% from its late-December 2025 low to approximately US$17,635 per tonne by April 2026. HPAL utilisation at operating plants fell to 70 to 75%, forcing smelters to import Philippine ore and reduce run rates.

President Prabowo Subianto, who took office in October 2024, has continued Indonesia's resource nationalism. Energy Minister Bahlil Lahadalia has publicly stated a target LME nickel price of US$19,000 to US$20,000 per tonne as a policy goal. The macroeconomic backdrop complicates corporate planning: the Indonesian rupiah broke through 18,000 per US dollar in June 2026, as tracked in the currency crisis node, squeezing rupiah earnings and raising the cost of imported sulphuric acid.

Relationships

Vale Indonesia, majority-owned by Brazil's Vale SA, operates the legacy Sorowako concession. Tsingshan Holding Group is the dominant force in nickel pig iron at Morowali. Huayou Cobalt, a Chinese EV materials company, is the leading HPAL investor, with plants at Weda Bay. The downstream HPAL product, mixed hydroxide precipitate, feeds battery cathode manufacturers that supply global EV assemblers including CATL, LG Energy Solution, and their automotive customers. The EU filed a WTO dispute in 2022 challenging Indonesia's export ban; a ruling is pending. The US has sought a bilateral critical minerals agreement to qualify Indonesian nickel under the US Inflation Reduction Act's sourcing rules, but terms remained unresolved as of mid-2026.

What to watch

The outcome of the 2026 mid-year supplementary RKAB round will determine whether Indonesian smelters can restore full run rates before the end of the year. Sulphuric acid supply is a structural bottleneck: no major new acid plants are commissioned inside Indonesia. The WTO ruling on the EU nickel dispute, anticipated in late 2026, could compel Jakarta to restructure the export-ban architecture. Any sustained shift in global EV battery chemistry toward lithium iron phosphate, which requires no nickel, would reduce demand for Indonesian MHP and undercut the downstream-processing rationale. A weaker rupiah raises the cost of imported industrial gases and acids, compressing HPAL margins further.
