Indonesia has approved a 2026 nickel ore production quota of approximately 260 million to 270 million wet tonnes, sharply below the 379 million tonnes approved under the 2025 RKAB system, according to reporting by Mysteel.
The reduction of more than 100 million tonnes places renewed pressure on the country’s smelting industry and has increased uncertainty over the availability of nickel units for stainless steel and battery-material production. It has also made the market more sensitive to quota revisions, mine-level approvals and signs of smelter curtailments.
Indonesia is the world’s largest mined-nickel supplier, giving decisions made under its annual Work Plan and Budget, known as RKAB, an influence that extends well beyond the country’s mining sector.
2026 target is well below 2025 approval
Indonesia’s Ministry of Energy and Mineral Resources approved the 2026 nickel ore quota at between 260 million and 270 million wet tonnes, Mysteel reported, citing Director General of Minerals and Coal Tri Winarno.
The approved range is approximately 29% to 31% below the 379 million tonnes approved for 2025:
| Indicator | 2025 | 2026 | Change |
|---|---|---|---|
| Indonesia nickel ore RKAB quota | 379 Mt | 260–270 Mt | Down 109–119 Mt |
| Approximate percentage change | : | : | Down 29–31% |
| ESDM estimated 2026 production | : | 209 Mt | Below approved quota |
Sources: Mysteel and reported Indonesian industry coverage. Figures refer to wet metric tonnes of nickel ore and are not directly comparable with refined nickel output.
The quota is an approved ceiling rather than a guaranteed production volume. Actual output can be lower because of weather, mine development schedules, permitting, contractor availability, infrastructure constraints and the timing of company-level approvals.
Mysteel subsequently reported that ESDM estimated Indonesia’s actual 2026 nickel ore production at approximately 209 million tonnes, nearly 20% below the 260–270 million-tonne RKAB range. The ministry said the lower production estimate was intended to preserve reserves and support commodity-price stability.
That difference between the formal quota and expected realized production is now central to the market outlook. A national ceiling of 260 million tonnes would already constrain supply relative to last year. Production closer to 209 million tonnes would create a considerably tighter operating environment for smelters.
Indonesian nickel supply is increasingly being managed through mine-level quotas and selective revisions.
RKAB revisions remain the main uncertainty
Indonesia’s quota system is designed to give the government greater control over mineral extraction and resource conservation. It also allows authorities to adjust approvals as market conditions, domestic processing requirements and reserve concerns change.
For miners and smelters, however, the system creates uncertainty when revisions are not published through a predictable, rules-based process.
The Indonesia Nickel Miners Association, or APNI, has called for additional production to be granted selectively to operations facing feedstock shortages. In reporting published by Mining Weekly, the association said any increases should be directed primarily to smelters with immediate raw-material needs rather than applied as a broad national expansion.
APNI also recommended an additional 30 million tonnes of production as a strategic buffer, which would bring the total closer to 300 million tonnes. The association said new smelting capacity expected to come online in 2026 would add to demand for ore.
The government has indicated that additions will be considered in the context of resource sustainability, domestic smelting requirements and primary energy availability. That leaves the market watching for three separate signals:
- Whether supplementary quotas are approved.
- Which miners and smelters receive them.
- Whether revisions alter the national supply ceiling or only redistribute available volumes.
The distinction matters. Selective additions could keep strategically important plants operating without restoring the supply levels seen in 2025. A broad increase, by contrast, would reduce the immediate risk of a domestic ore shortage but could weaken the price-support effect of the original cut.
Smelters face a feedstock mismatch
Indonesia’s downstream nickel industry has expanded faster than permitted mine supply. Mining Weekly reported that Indonesia has around 80 nickel smelters and that these facilities could consume approximately 315 million tonnes of ore per year if operating at full capacity.
Domestic nickel ore consumption reached 142.96 million tonnes between January and July, according to APNI. That represents around 53% to 55% of the annual quota, based on the association’s calculations, but the pace of consumption does not resolve the availability problem for the remainder of the year.
The exposure is particularly significant for facilities that depend on regular deliveries of saprolite or limonite ore with specific grade and moisture characteristics. Ore cannot always be substituted across processing routes. A shortfall in one grade or region may therefore affect a plant even when total national inventories appear adequate.
Smelter operators may respond by:
- Reducing utilization rates.
- Delaying maintenance completion or commissioning schedules.
- Prioritizing higher-margin nickel products.
- Seeking additional ore from approved suppliers.
- Increasing reliance on stockpiled material.
- Competing more aggressively for available domestic feed.
Smelter utilization will depend on both national quota volumes and the grade, location and timing of available ore.
A prolonged feedstock gap could also affect electricity demand, logistics volumes and the economics of integrated industrial parks. Plants operating below capacity may face higher unit costs, while miners with secure approvals could gain greater negotiating leverage over ore pricing.
Market reacts to policy signals
Nickel prices have become increasingly responsive to Indonesian policy announcements because the country accounts for a dominant share of global mined supply and a growing share of refined and intermediate production.
The ore quota itself does not translate one-for-one into refined nickel supply. Processing yields vary, and the market also includes inventories, nickel pig iron, ferronickel, matte, mixed hydroxide precipitate and refined class-one nickel. These materials can move through different supply chains and may not tighten simultaneously.
Even so, the quota reduction has narrowed the market’s margin for error. When supply was expanding rapidly, disruptions could be absorbed through additional Indonesian output or rising inventories. With a lower production ceiling, delays at individual mines or smelters can have a larger impact on prompt availability.
Mining Weekly quoted APNI Secretary General Meidy Katrin Lengkey as saying that a lack of transparency around quota revisions could cause the global market to overreact to individual company decisions. The association linked that uncertainty to volatility in London Metal Exchange nickel prices earlier in August.
The immediate price response may be uneven. Higher ore costs can support nickel prices and improve the position of producers with secure feedstock. But elevated prices may also encourage substitution, reduce stainless steel consumption or prompt battery manufacturers to favor chemistries that use less or no nickel.
Stainless steel remains the key demand variable
Stainless steel is still the largest source of nickel demand. That makes Chinese industrial activity, construction, manufacturing and stainless production important determinants of whether tighter Indonesian ore supply translates into a sustained refined-nickel deficit.
A resilient stainless market would increase competition for Indonesian ore and strengthen the effect of the quota reduction. Weak industrial demand could limit the price response, particularly if existing refined inventories remain high.
Battery demand offers additional growth, but the outlook is more complicated. Nickel-rich cathode chemistries remain important for applications where energy density and driving range are priorities. At the same time, lithium-iron-phosphate batteries, which do not use nickel, have gained market share in several segments.
The result is a market with a firm supply-side constraint but an uncertain demand response. Indonesia can tighten ore availability, but the effect on prices will depend on how quickly stainless steel demand absorbs the reduction and how much battery demand is exposed to chemistry shifts.
What operators and investors should monitor
The 2026 nickel market will be shaped less by the headline quota alone than by the gap between approved capacity and actual material movement.
Key indicators include:
- Monthly Indonesian mine production against the 260–270 million-tonne quota.
- ESDM announcements on supplementary RKAB approvals.
- Mine-level quota allocations and delivery schedules.
- Ore premiums by grade and region.
- Smelter utilization and temporary operating cuts.
- Stockpile levels at industrial parks and ports.
- LME inventories and regional refined-nickel availability.
- Chinese stainless steel output.
- Changes in battery chemistry and nickel-intensive cathode demand.
The critical question is whether Indonesia’s policy is creating a temporary adjustment or a lasting supply discipline regime.
For now, the answer remains uncertain. The formal 2026 quota is materially below 2025’s approval, while ESDM’s lower production estimate suggests that realized supply could be tighter still. Selective quota additions may prevent a disorderly smelter shutdown cycle, but they are unlikely to remove the market’s exposure to delays and policy surprises.
Indonesia’s 260–270 million-tonne target has therefore changed the balance of risk in nickel. The market may not move directly from surplus to shortage, but a smaller supply cushion means that each RKAB revision, mine disruption and smelter feedstock warning is likely to carry greater price significance.
