Battery Metals and Rare Earths: Lithium, Nickel, Cobalt — 2026-09-11
China's August rare earth exports fell 18.2% year-on-year, reinforcing supply tightness ahead of potential November export control reinstatements. Meanwhile, Indonesia's nickel state revenue doubled to Rp21 trillion despite lower production volumes, while lithium markets face volatility due to methodology changes in inventory data that have confounded traders and pressured prices.

Top developments
China’s August Rare Earth Exports Drop 18.2% YoY
China shipped out 4,735 metric tons of rare earths in August 2026, an 18.2% decrease compared to the same month in 2025. This volume remains below the year-to-date monthly average, signaling continued constraint in global supply chains as Beijing maintains strict oversight on critical mineral flows. The drop underscores the persistent impact of previous regulatory measures and raises concerns for downstream manufacturers relying on Chinese feedstock for magnets and battery components.
Indonesia Nickel PNBP Doubles to Rp21 Trillion
The Indonesian Ministry of Energy and Mineral Resources (ESDM) reported that non-tax state revenue (PNBP) from nickel reached Rp21 trillion by the end of August 2026, a two-fold increase from previous periods. This surge occurred despite a reduction in ore production, with data indicating 17.379 million tons extracted by September 1, 2026, compared to higher volumes in prior years. The revenue boost is attributed to the "hilirisasi" (downstreaming) policy, which mandates domestic processing, thereby capturing more value within Indonesia rather than exporting raw ore.
Lithium Inventory Methodology Shift Confounds Traders
A sudden surge in reported lithium stockpile data in China, resulting from a change in calculation methodology, has disrupted market sentiment and weighed on prices. Traders are calling for regulatory clarity as the new figures contradict previous expectations of tight supply, leading to increased price volatility for lithium carbonate. This development complicates short-term forecasting for battery manufacturers who rely on stable input costs.
Cobalt Rally Fades as DRC Export Quotas Take Effect
Cobalt prices are reversing their recent upward trend as exports from the Democratic Republic of Congo (DRC) increase under a newly implemented quota system. Kinshasa’s strategy to control prices through supply management is being tested by rising actual export volumes, which have alleviated some immediate scarcity fears. The fading rally suggests that while policy constraints remain, market dynamics are adjusting to the new regulatory framework in Africa’s primary cobalt source.
Local view
Indonesia: Local media outlets Media Indonesia and Antara News highlight the success of the government's downstreaming (hilirisasi) policy, noting that nickel state revenue (PNBP) has doubled to Rp21 trillion by August 2026. Stakeholders emphasize that this achievement occurred despite lower raw ore extraction volumes, validating the economic strategy of forcing domestic smelting. However, analysts warn that El Niño-induced droughts at major smelter hubs like IMIP could threaten future export capabilities of processed nickel products.
Latin America: Rio Times reports diverging performance in lithium equities, with Chilean producer SQM and Albemarle shares sliding while South American carbonate prices remained firm. The divergence reflects investor caution amidst inventory uncertainty and geopolitical tensions regarding China's influence over regional lithium supply chains.
Context & numbers
- Rare Earths: China exported 4,735 metric tons in August 2026, down 18.2% YoY.
- Nickel Revenue: Indonesia's nickel PNBP reached Rp21 trillion (~$1.35 billion USD approx.) by August 31, 2026.
- Nickel Production: Indonesia mined 17.379 million tons of nickel ore through September 1, 2026, a significant reduction from the 32.037 million tons produced in all of 2025, reflecting tighter RKAB quotas.
- Copper Benchmark: Copper hit an intraday high of $14,779/t on September 9, closing at $14,708/t, providing a broader metals market context.
On the radar
- November Export Control Deadline: Market participants are bracing for the potential reinstatement or tightening of China's rare earth export controls in November 2026, following the one-year suspension announced in late 2025. Refiners and recyclers outside China are assessing risks to technology and feedstock access.
- El Niño Impact on Indonesian Smelters: Analysts are monitoring the effects of El Niño-driven droughts on hydropower-dependent smelters in Indonesia, particularly the IMIP facility, which could reduce processed nickel output and global exports.
