Why Nickel Is Critical
Nickel is the essential industrial metal of the 21st century. From EV batteries to medical stainless steel, from aerospace superalloys to construction structures — nickel is present throughout the modern economy. As US tariffs escalate and China's trade dominance deepens, nickel demand is accelerating exponentially as the world transitions to renewable energy and electric vehicles.
EV Batteries (Lithium-ion)
Nickel is a critical component in NMC (Nickel-Manganese-Cobalt) and NCA (Nickel-Cobalt-Aluminium) lithium-ion cathodes. Each mid-range EV needs 30–60 kg of nickel — no nickel, no electric vehicles.
Stainless Steel
Over 70% of global nickel goes into stainless steel — from kitchen utensils and surgical tools to structural construction. Stainless pots, refrigerators, and aircraft all need nickel.
Superalloys
Jet turbines, rockets, and nuclear reactors use nickel-based superalloys capable of withstanding extreme heat and pressure — a domain with no viable substitutes.
Without Nickel
EV prices would skyrocket. Steel production would stall. Defense supply chains would fracture. The Net Zero 2050 target would become practically impossible.
Indonesia's Nickel Supremacy
Indonesia is not merely the world's largest nickel producer — it holds approximately one-third of all proven global nickel reserves. With 21.5 million tonnes of proven reserves and output of 1.6 million tonnes per year (2022), Indonesia is the only country capable of meeting the explosive surge in battery-grade nickel demand during the EV decade. Indonesian nickel is concentrated mainly in Sulawesi (Central and Southeast Sulawesi provinces) and the Maluku islands (especially North Halmahera — home to the massive Weda Bay mine).
Indonesia Nickel Deposit Distribution
The Raw Ore Export Ban Strategy
In 2020, Indonesia banned raw nickel ore exports — a bold move forcing foreign investors to build processing facilities inside Indonesia rather than simply extracting raw materials. The EU filed a WTO complaint. The WTO ruled for the EU. Indonesia... ignored the ruling. Result: Indonesia's nickel refining sector grew 500%+ in five years, attracting tens of billions in direct foreign investment.
WTO Paradox: International Law vs. Resource Sovereignty
The WTO ruling against Indonesia reveals the fundamental tension between free trade law and developing countries' sovereignty over natural resources. Indonesia argues: nations have the right to process resources domestically to create added value. The West fears: this precedent will be followed by other resource nations (DRC, Philippines, Zambia).
The US–China Battle for Jakarta
Indonesia is playing a precarious strategic balancing act: accepting tens of billions in Chinese investment in nickel refining while maintaining defense and diplomatic relations with the US. Washington is increasingly alarmed that Beijing is locking up global EV battery supply chains through its dominance of Indonesian smelting.
- CATL, Tsingshan, GEM pour tens of billions into Indonesian nickel smelters
- China controls 70%+ of Indonesia's nickel refining capacity
- Deep investment ties since 2015, BRI (Belt and Road Initiative) projects
- China aims to lock up the global EV battery supply chain from raw inputs
- US Critical Minerals Act seeks to reduce Chinese dominance in EV battery chains
- Freeport-McMoRan + Antam JV is the US-aligned model
- US pressuring Indonesia to join a 'trusted minerals network'
- Advantage: defense ties, technical aid — but cannot match Chinese FDI scale
Indonesia: Balancing Diplomacy
Indonesia pursues its 'free and active' (bebas aktif) foreign policy — non-aligned with any major power. President Prabowo Subianto (2024–) maintains Chinese investment in smelting while deepening defense ties with the US, Australia, and Japan. Indonesia's goal: to be 'supplier to all' — not a vassal of any.
Companies Shaping the Nickel Chain
From mining to battery production — these corporate giants are jockeying for position in Indonesia's nickel value chain.
CATL
ChinaContemporary Amperex Technology — holds ~37% of the global EV battery market. CATL has invested billions in Indonesian nickel processing plants to secure raw material supply for its EV battery production lines.
LG Energy Solution
South KoreaLG Energy Solution — battery supplier for Tesla, GM, Hyundai. Negotiating long-term nickel contracts with Indonesia, competing with CATL in the race to secure battery supply for the EV decade.
Vale
BrazilVale is one of the world's largest nickel miners, operating the Sorowako mine in Sulawesi since the 1960s. Vale is expanding partnerships with Chinese partners to meet surging demand for battery-grade nickel.
Glencore
SwitzerlandGlencore — a multinational commodity trading and mining giant. Present in Indonesia through long-term trading contracts with local producers, positioning itself as a key intermediary in the nickel value chain.
Freeport-McMoRan + Antam
USA + IndonesiaFreeport-McMoRan (USA) partners with Antam (Indonesian state enterprise) in downstream nickel processing JVs — aligned with the US strategy to reduce Chinese dominance over battery mineral supply chains.
The Weda Bay Crisis — When Indonesia Turned the Tap
In February 2026, Indonesia cut the mining quota at Weda Bay mine — Indonesia's largest nickel mine, operated by Tsingshan Holdings (China) and Eramet (France) in North Halmahera. The decision immediately shocked markets: nickel prices on the London Metal Exchange (LME) surged sharply, sending tremors through global EV battery supply chains. Analysts see this not as a random incident — but as a deliberate signal from Jakarta that Indonesia can and will use nickel as a geopolitical weapon.
From Ore to Electric Vehicle
The journey of one tonne of Indonesian nickel on its way to becoming a global EV battery.
Ore Extraction
Mining laterite nickel ore in Sulawesi & Halmahera, Indonesia
RKEF/HPAL Refining
Indonesian smelters convert ore into NPI (Nickel Pig Iron) or MHP (Mixed Hydroxide Precipitate)
Cathode Processing
Chinese/Korean plants convert MHP into nickel sulfate for batteries
Battery Manufacturing
CATL, LG, Panasonic assemble NMC lithium-ion battery packs for EVs
EV Assembly
Tesla, BYD, Hyundai, VinFast assemble electric vehicles using nickel batteries
Consumer
Electric vehicles reach buyers in the US, EU, China, and Southeast Asia
▸ If you buy an electric vehicle (EV) in 2026, battery prices could rise 10-15% as Indonesia tightens raw nickel exports -- directly affecting Tesla, BYD, and VinFast pricing.
The Environmental Cost of 'Green' Nickel
Nickel is marketed as the raw material of the green economy — but the mining and smelting process in Indonesia is leaving deep wounds on rainforests, water sources, and local communities. This is the greatest paradox of the renewable energy century.
Sulawesi & Halmahera Deforestation
Over 1 million hectares of rainforest sit under nickel mining permits. Sulawesi and Halmahera have already lost hundreds of thousands of hectares of primary forest to mine expansion.
Water Pollution
Wastewater from nickel smelting contains heavy metals (chromium, cobalt) flowing into rivers and coastal areas of Sulawesi. Many fishing communities have lost their livelihoods due to localized ocean pollution.
Community Displacement
Tens of thousands of indigenous people have been forcibly relocated as nickel mines expand onto ancestral lands. Land disputes and social conflicts are rising in North Maluku and Central Sulawesi.
Greenhouse Gas Paradox
RKEF smelters burn coal to process nickel — the paradox being that nickel is used to make 'green' EVs, yet the production process emits enormous amounts of CO₂.
Each tonne of nickel refined in Indonesia (using coal-fired RKEF furnaces) emits approximately 40–80 tonnes of CO₂. At 1.6 million tonnes per year, Indonesia's nickel industry emits approximately 64–128 million tonnes of CO₂ annually — equivalent to many medium-sized countries. EVs powered by Indonesian nickel batteries may not be 'greener' than petrol cars when full production lifecycle emissions are counted.
ASEAN's Nickel Lessons
Indonesia's nickel strategy is becoming the template for the entire Southeast Asian region — especially Vietnam, which holds an untapped treasury of critical minerals. The lessons from Jakarta are being studied carefully in Hanoi.
ASEAN Critical Minerals Framework 2026
ASEAN is negotiating a Critical Minerals Framework to coordinate export policies, attract investment, and reduce dependence on any single major power.
Vietnam's Mineral Strategy
Vietnam holds the world's 2nd-largest rare earth reserves (22 million tonnes) and 3rd-largest bauxite (5.8 billion tonnes). Vietnam is studying Indonesia's lesson — banning raw exports to force domestic processing.
FDI Attraction Competition
Indonesia and the Philippines fiercely compete for nickel processing FDI from South Korea, Japan, and the US — as a counterweight to the dominant wave of Chinese FDI.
Mineral Geopolitics
The battle for Indonesia's nickel is the template for a new world order: strategic minerals = geopolitical power. ASEAN is learning to turn resources into diplomatic leverage.
Vietnam holds the world's 2nd-largest rare earth reserves (22 million tonnes, second only to China's 44 million tonnes), plus 3rd-largest bauxite (5.8 billion tonnes), titanium, and wolframite. If Vietnam applies the 'ban raw exports + force domestic processing' strategy like Indonesia, this could be the greatest economic and diplomatic lever in the country's history — especially as the US actively seeks to escape dependence on Chinese mineral supply chains.
