Indonesia's decision to aggressively manage nickel ore supply has transformed the global nickel market outlook from chronic surplus to emergent deficit. The RKAB (Rencana Kerja dan Anggaran Biaya) ore production quota system, introduced to regulate Indonesia's vast nickel mining sector, was tightened significantly for 2026. The approved quota of 260-270 million wet tonnes compares to 379 million tonnes allocated in 2025—a reduction of roughly one-third. This is not a market-driven supply response; it is a deliberate government policy to curb overproduction, support prices, and conserve ore resources for domestic downstream processing.
The impact on Indonesian nickel production has been immediate. Several mining operations, including a PT Vale Indonesia facility, have experienced operational halts due to delayed RKAB approvals. The quota enforcement has been uneven—some miners received approvals early while others waited months—creating supply uncertainty that ripples through Indonesia's nickel pig iron (NPI) and matte production chains. Analysts describe Indonesia as entering a 'managed-supply regime' where the government targets an LME nickel price corridor of approximately $20,000-22,000/t, viewing this as the level that supports domestic industry profitability without incentivizing substitution.
The INSG's revised forecast reflects both the Indonesian supply constraint and improving demand. Primary nickel production is now forecast at 3.715 million tonnes in 2026, while consumption is projected at 3.747 million tonnes, yielding the 32,000-tonne deficit. This is a remarkable swing from earlier forecasts that had the nickel market drowning in surplus for years to come. The surplus narrative had been so dominant through 2023-2025 that LME nickel prices tested $15,000/t multiple times, and analysts wrote off nickel as a structurally oversupplied market.
LME nickel inventories at 274,434 tonnes remain elevated by historical standards—the five-year average before 2022 was closer to 150,000 tonnes—but the direction of travel has changed. Stocks have been declining modestly through Q2 2026, and more importantly, the composition of LME stocks matters. A significant portion consists of Indonesian-origin NPI and Chinese nickel sulfate that is not deliverable against the LME's Class 1 nickel contract. The effectively available Class 1 nickel (high-purity cathodes, briquettes, and pellets) in LME warehouses is a fraction of the headline number.
Demand for nickel continues to grow from two distinct end-use sectors with different dynamics. Stainless steel, which accounts for approximately 64% of global nickel consumption, has seen improving demand from Chinese mills heading into 2026. Chinese stainless steel production rose approximately 5% year-on-year in H1 2026, supported by infrastructure spending and manufacturing activity. After a period of destocking through 2024-2025, stainless steel buyers have returned to the market.
The battery sector, representing about 15% of nickel demand, presents a more nuanced picture. Electric vehicle production continues to grow at roughly 20% annually, and nickel-rich cathode chemistries (NMC, NCA) remain dominant in premium and long-range EVs. However, the shift toward lithium iron phosphate (LFP) batteries, which contain no nickel, has moderated the growth trajectory for nickel demand from batteries. LFP's market share in China has risen above 60% of new EV battery installations, limiting nickel demand growth from the world's largest EV market.
The interplay between stainless steel and battery demand creates a floor for nickel consumption growth even if EV battery chemistry continues to shift. Stainless steel demand is cyclical and tied to industrial production, while battery demand is structural and tied to the energy transition. Together, they provide a diversified demand base that grew approximately 4-5% in 2025 and is expected to grow at a similar rate in 2026.
On the policy front, Indonesia's nickel strategy extends beyond production quotas. The government has signaled intentions to restrict exports of intermediate nickel products—NPI and matte—to force further downstream processing within Indonesia. Export taxes on NPI have been discussed, and the long-term trajectory points toward Indonesia exporting more refined nickel sulfate and cathode precursor materials rather than intermediate products. For global nickel markets, this means the supply chain is becoming more concentrated in Indonesia, creating single-point-of-failure risk for a commodity critical to both stainless steel and EV battery supply chains.
Nickel buyers should reassess their sourcing strategies in light of Indonesia's shift from market share to price management. The days of buying nickel at $15,000-16,000/t appear to be over for this cycle. For stainless steel producers: the NPI market is where Indonesian policy has the most direct impact. Secure NPI supply agreements with diverse Indonesian producers to mitigate RKAB-related delivery risk. Monitor the Indonesian government's monthly RKAB approval announcements—these have become the single most important data point for nickel supply. For battery manufacturers and cathode producers: the shift to LFP reduces your nickel exposure, but if your product portfolio includes NMC/NCA chemistries, the concentration of nickel sulfate supply in Indonesia is a strategic risk. Consider qualifying nickel sulfate from non-Indonesian sources (Australia, New Caledonia, Canada) even at a premium to maintain supply chain diversity. For procurement teams across all nickel-consuming sectors: budget for LME nickel between $18,000-22,000/t through H2 2026. The probability of a return to $15,000/t is low given the Indonesian quota cuts; the probability of a spike above $25,000/t if additional supply disruptions occur is moderate but non-trivial.
