Nickel prices on the London Metal Exchange (LME) recently touched a three-week high of approximately US$17,000 per tonne, signaling a potential shift in a market long defined by oversupply. This price action comes as Indonesia, the world’s dominant producer responsible for over half of global supply, signals a pivot toward production discipline. For the nickel market outlook 2026, the convergence of tightened ore quotas (RKAB) and a critical shortage of sulfuric acid is creating a new floor for prices and challenging the assumption of a persistent, easy-to-manage surplus.
The primary driver behind this volatility is Jakarta’s revision of the Work Plan and Budget (RKAB) mining quotas. For 2026, the Indonesian energy ministry has indicated plans to restrict nickel ore output to a range of 260–270 million tonnes, a significant reduction from the approximately 320 million tonnes approved for 2025. This policy shift is compounded by logistics-driven input shortages, specifically for sulfuric acid, which is essential for the High-Pressure Acid Leach (HPAL) plants that produce battery-grade nickel.
Indonesia’s RKAB Pivot: From Volume to Value
Indonesia’s strategy for 2026 reflects a transition from aggressive volume growth to a focus on resource conservation and price stabilization. By tightening the RKAB approvals, the government is effectively setting a supply ceiling that prevents the market from being flooded with low-cost ore.
Current reporting indicates that several major operators, including Vale Indonesia, have seen their 2026 approved mining quotas come in at only 30% of requested levels. This restrictive environment is designed to force efficiency and environmental compliance, but its immediate effect is a reduction in ore availability for the country’s massive smelting sector.
For operators in South Sulawesi and Central Sulawesi, the quota squeeze is already being felt. Several smelting lines are reportedly operating at utilization rates below 50% due to the lack of high-grade saprolite ore. This utilization gap represents a structural shift in the Indonesian nickel landscape, moving away from the era of uncapped expansion that characterized the early 2020s.
The Sulfuric Acid Bottleneck and HPAL Constraints
While ore quotas impact the raw material supply, a shortage of sulfuric acid is creating a secondary bottleneck in the processing of battery-grade nickel intermediates, such as Mixed Hydroxide Precipitate (MHP). HPAL technology relies heavily on sulfuric acid to leach nickel and cobalt from limonite ore.
The shortage is largely driven by geopolitical tensions in the Middle East, specifically the Iran–US/Israel conflict, which has disrupted global sulfur trade routes. Granular sulfur prices have spiked from below US$600 per tonne to as high as US$1,000 per tonne.
This input cost shock has multiple implications:
- Production Curtailments: Several Indonesian HPAL projects have slowed production or delayed expansion plans due to the unavailability or prohibitive cost of acid.
- Lifted Cost Floor: The higher cost of chemical inputs has effectively raised the marginal cost of production for battery-grade nickel, providing a floor for LME prices near the current US$17,000 level.
- Supply Chain Friction: Until shipping routes normalize and sulfur prices retreat, the expected wave of "green nickel" supply from Indonesia may be more constrained than previous forecasts suggested.
Nickel Market Balance: 2026 Outlook and Data Points
Despite these constraints, the consensus among major financial institutions remains that the nickel market will stay in a technical surplus through 2026, though the margin of that surplus is narrowing. Sumitomo Metal Mining (SMM) currently forecasts a global nickel surplus of approximately 256,000 tonnes for 2026. However, if Indonesian quota enforcement remains strict, that surplus could be eroded by as much as 100,000 tonnes.
| Metric | 2026 Base Case | 2026 Bull Case | 2026 Bear Case |
|---|---|---|---|
| LME Price (Avg/t) | US$17,000 – 18,000 | US$18,500 – 20,000+ | US$15,500 – 16,000 |
| Indonesian Ore Quota | 260M – 270M tonnes | < 250M tonnes | > 320M tonnes (Revised) |
| Global Market Balance | ~256k tonne Surplus | ~120k tonne Surplus | > 300k tonne Surplus |
| Sulfur Price (Input) | US$750 – 850/t | > US$1,000/t | < US$600/t |

The "Bull Case" scenario is increasingly tied to the persistence of Indonesian policy discipline. If Jakarta maintains the 260 million tonne cap and uses it as a lever for environmental and social governance (ESG) reform, the market could rebalance much faster than analysts anticipated in late 2025.
Implications for the Battery Supply Chain
The tightening of the Indonesian market is particularly significant for the EV battery supply chain. Unlike the stainless steel sector, which can utilize lower-grade Nickel Pig Iron (NPI), battery manufacturers require Class 1 nickel or intermediates like MHP.
As the acid shortage persists, the premium for battery-grade nickel over NPI is expected to widen. Investors and procurement managers should monitor the "Green Nickel" narrative; as Indonesia faces pressure to clean up its energy-intensive smelting operations, the cost of compliance will likely be passed through the value chain.
Furthermore, the operational complexity of managing restricted quotas and volatile input costs is driving a new era of consolidation in the Indonesian nickel belt. Large-scale players with integrated supply chains: from mining to refined product: are better positioned to weather the acid shortage than smaller, independent smelters that rely on spot-market ore and chemicals.
Operational Efficiency and Real-Time Monitoring
In an environment where ore availability is restricted, operational efficiency becomes the primary differentiator. Modern mining facilities in Indonesia are increasingly adopting real-time monitoring and advanced fleet management to maximize every tonne of approved quota.
From integrated control rooms, operators can coordinate logistics to ensure that high-grade ore is blended correctly and that processing plants are not idling during periods of supply disruption. As Skillings has previously noted in its coverage of mining technology and automation, the ability to integrate live data is no longer a luxury but a requirement for surviving the 2026 supply squeeze.
Summary of Risks for 2026
While the current US$17,000 per tonne level reflects a more balanced sentiment, several risks remain:
- Policy Reversals: Indonesia has a history of revising RKAB quotas mid-year. If Jakarta lifts the cap to 300–350 million tonnes in a second-half review, the current price support could evaporate.
- Geopolitical Normalization: A peace deal or improved maritime security in the Middle East would quickly lower sulfuric acid costs, allowing curtailed HPAL production to return to the market.
- Macro Demand: A slowdown in global EV adoption or a shift toward LFP (lithium-iron-phosphate) batteries, which do not require nickel, could reduce the demand pressure regardless of supply-side constraints.
For decision-makers, the 2026 nickel market is no longer a "race to the bottom" in terms of pricing. It has become a complex landscape defined by regulatory hurdles and chemical supply chain logistics. Staying informed on the daily shifts in Indonesian policy remains the most critical task for those navigating the nickel market outlook 2026.

Nickel Market Update: LME prices hit a 3-week high of $17k/t as Indonesia tightens its 2026 mining quotas to 260-270M tonnes. Combined with a global sulfuric acid shortage hitting HPAL plants, the narrative of an endless nickel surplus is facing its first major test of 2026.
Key Takeaways:
- RKAB quotas are down significantly from 2025 levels.
- Sulfur prices near $1,000/t are squeezing battery-grade margins.
- Sulawesi smelter utilization dropping below 50% on some lines.
