AI summary card
WBN quota increase scenario is broadly manageable, but may squeeze other miners' quotas and create near-term valuation pressure
As of August 6, 2026, WBN had not yet received approval for additional RKAB; even if it receives an additional 25 million wet tonnes of quota in the second half, UBS believes sector supply and demand can still be broadly balanced, but other miners may receive smaller quotas or face lower nickel prices if there is no overall cap.
- Indonesia's Ministry of Energy and Mineral Resources denied that WBN had received an additional 25 million wet tonnes of nickel ore quota, and UBS channel checks also show that as of August 6, 2026, there was no formal revision result.
- News of the quota increase once drove nickel prices down 2.2% to US$16,735/tonne, reflecting the market's high sensitivity to supply expansion.
- UBS's base-case scenario is for the sector RKAB in 2026 to be below 300 million wet tonnes; if WBN is approved for 25 million wet tonnes in the second half, this would be broadly in line with that view, and the supply-demand impact is expected to be manageable.
- If 300 million wet tonnes represents the sector cap, WBN's quota increase may mean other miners receive fewer approved volumes or quotas below expectations, weighing on related stock performance.
- If there is no sector quota cap, most miners may still receive additional quotas, but increased ore supply would further depress nickel prices.
Report interpretation
Overview
The report assesses the industry impact of PT Weda Bay Nickel potentially obtaining an additional 25 million wet tonnes of 2026 nickel ore RKAB. Indonesian regulators have denied rumors that the relevant quota was approved, and UBS channel checks as of August 6, 2026, also found no formal announcement of a revised RKAB. The research believes WBN is an important supply swing factor for nickel prices, but under the base assumption that the 2026 sector RKAB does not exceed about 300 million wet tonnes, the impact of its quota increase on full-year supply and demand remains manageable. The main uncertainty lies in whether the quota squeezes other miners and whether regulators loosen the sector-wide volume constraint.
Core views
UBS believes that WBN obtaining a 25 million wet tonne quota in the second half would not automatically lead to significant sector oversupply. Based on first-half ore consumption accounting for 40% to 45% of the full year, first-half consumption of 120 million wet tonnes implies full-year consumption of 267 to 300 million wet tonnes. Combined with 23 million wet tonnes of imports, demand of 322 million wet tonnes and an RKAB of 300 million wet tonnes, global supply and demand in 2026 are broadly balanced, with Indonesian nickel ore and refined nickel output expected to decline 3% and 2% year over year, respectively. However, the market path depends on the quota regime: if 300 million wet tonnes is the cap, WBN's quota increase will squeeze other miners; if there is no cap, broad quota increases would depress nickel prices through supply expansion. Regulators may also reduce near-term price volatility through limited or delayed announcements.
Analysis framework
The report conducts scenario analysis by combining regulators' statements, channel checks with Indonesian miners, first-half RKAB approval status, seasonality of ore consumption, import volumes and annual demand assumptions. It uses whether 300 million wet tonnes constitutes the sector quota cap as the dividing line to assess the impact of WBN's quota increase on nickel prices, sector supply and demand, and listed miners. Equity valuation uses the sum-of-the-parts method.
Methodology notes
Quantitatively match domestic RKAB, import volumes and sector demand
Using a 2026 RKAB of 300 million wet tonnes, imports of 23 million wet tonnes and demand of 322 million wet tonnes as core assumptions, the report judges that full-year global supply and demand are broadly balanced and estimates changes in Indonesian ore and refined nickel output.
Compare two paths: the sector having or not having a 300 million wet tonne quota cap
When a cap exists, WBN's quota increase mainly squeezes other miners' quotas; when no cap exists, more miners may receive approvals, but incremental supply will exert stronger pressure on nickel prices.
Extrapolate full-year consumption based on first-half consumption accounting for 40% to 45% of the full year
First-half consumption of 120 million wet tonnes corresponds to about 267 to 300 million wet tonnes for the full year, which is used to test whether sector quotas and supply can meet annual demand.
Estimate company value by summing the value of each business or asset
UBS uses the sum-of-the-parts method to value covered mining companies including ANTM, MBMA, NIC, NCKL and INCO.

Key data
- Rumored additional RKAB for WBN25 million wet tonnesRumors suggested WBN's 2026 RKAB would be raised from 12 million wet tonnes to 37 million wet tonnes, but this had not been officially confirmed as of August 6, 2026.
- WBN submitted quota42 million wet tonnesCompared with the approved 12 million wet tonnes, this indicates significant supply swing potential.
- Nickel price movement after the rumor-2.2% to US$16,735/tonneReflects investors' concern that even limited additional quotas could expand supply.
- UBS 2026 sector RKAB base caseBelow 300 million wet tonnesMiners with stronger downstream project pipelines are more likely to receive relatively better quotas.
- First-half approved RKAB indicated by miner surveyAbout 255 million wet tonnesBelow the approved volume of 260 to 270 million wet tonnes announced at the beginning of the year.
- 2026 ore demand assumption322 million wet tonnes, up 4% year over yearTogether with the 300 million wet tonne RKAB and 23 million wet tonnes of imports, this forms the supply-demand balance calculation.
- 2026 import assumption23 million wet tonnesImports in the first half of 2026 were 8.6 million wet tonnes, up 65% year over year.
- Maximum sector output with no quota capAbout 310 million wet tonnesMiners believe that even if the cap is removed, capacity constraints would still limit full-year output if new approvals arrive in August 2026.
- Indonesian nickel ore production forecastDown 3% year over yearBased on the 300 million wet tonne RKAB scenario.
- Indonesian refined nickel production forecastDown 2% year over yearBased on the report's supply-demand assumptions.
Impact & implications
Quota allocation, rather than WBN's single incremental volume itself, is the key factor affecting investment performance. If sector-wide volume is controlled, nickel price fundamentals are relatively stable, but other miners' production and earnings expectations may be revised down because their quotas are crowded out. If aggregate volume is not controlled, miners' production room expands, but this may be offset by falling nickel prices. Companies with strong downstream project pipelines, stronger ability to secure quotas and more resilient business structures are relatively advantaged, so UBS continues to list INCO as its top pick.
Risks
- Nickel prices lower than expected.
- Indonesian nickel supply stronger than expected or no aggregate cap on sector RKAB.
- Successful conversion of nickel pig iron into nickel matte, increasing the supply of nickel units available for batteries.
- Delays in Indonesian government nickel mining permits and RKAB issuance.
- Indonesian HPAL projects coming online faster than expected.
- Scrap use in nickel unit supply increasing faster than expected.
- Decline in China's metals demand.
- Worsening chip shortages leading to lower EV supply and nickel demand.
- Companies becoming more sensitive to the ESG attributes of nickel produced using non-coal power.
- Indonesia restricting new expansion of non-battery-grade nickel smelters.
- Other miners receiving lower-than-expected additional quotas due to WBN's quota increase.
