In January 2020, Indonesia banned the export of unprocessed nickel ore. The IMF warned against it. The EU filed a WTO case. Every established interest argued it would collapse investment and damage the economy. Indonesia held firm. Five years later, it supplies more than half the world's nickel, hosts the planet's largest battery material industrial parks, and has attracted $15 billion from Tsingshan alone. Raw nickel ore fetches $30–50 per tonne. Refined nickel sulphate for batteries commands $15,000–20,000 per tonne — a 300–400× value multiplication. Indonesia decided to capture that gap. This is how — and whether it worked.

The logic of Indonesia's export ban begins with a single number: the price difference between raw ore and finished product. Nickel, in its unprocessed form, is a relatively modest commodity — worth $30–50 per tonne when dug from the ground and loaded onto a bulk carrier. Process it into nickel pig iron for stainless steel, and it becomes worth several hundred dollars per tonne. Process it further, through high-pressure acid leaching, into battery-grade nickel sulphate, and it commands $15,000–20,000 per tonne. The same mineral, at different stages of processing, is worth 300–400 times more.
For decades, Indonesia — sitting on the world's largest nickel reserves, estimated at 22% of global total — had been exporting the cheap end of this value chain and watching other countries capture the expensive end. Japan processed Indonesian ore into ferronickel. China converted it into stainless steel and, increasingly, into the battery materials that power electric vehicles. Indonesia received the revenue of a raw material exporter while the value-added industries, the jobs, the technology, and the profits accumulated elsewhere. The export ban was a single-lever policy designed to force the world to come to Indonesia for the processing — or go without the nickel.
Indonesia had actually attempted an earlier version of this policy in 2014 — banning nickel ore exports as part of a broader minerals export restriction framework. It worked partially: Chinese investment in Indonesian nickel processing increased significantly, and Indonesia moved up the stainless steel value chain. But enforcement was inconsistent, and the ban was effectively suspended before being reimposed comprehensively in January 2020.
The 2020 ban was different in its commitment and its consequences. The European Union — which had been importing Indonesian nickel ore for stainless steel production — filed a complaint with the World Trade Organisation in November 2019, arguing that the export restriction violated WTO rules. The WTO ruled against Indonesia in 2022. Indonesia appealed and effectively blocked the ruling from being enforced by filing an appeal to a defunct appeals body — a deliberate legal strategy that neutralised the WTO mechanism while the domestic processing industry was built. The EU case became an inadvertent advertisement for the policy's effectiveness: the fact that Europe was willing to pursue WTO litigation proved that the ban was working.
Global nickel prices surged following the ban — Indonesia's share of world reserves meant the supply shock was real and immediate. But the more important consequence was investment redirection. Companies that had been buying Indonesian ore and processing it in China, Japan, and Europe faced a binary choice: build processing capacity in Indonesia or find an alternative source. For nickel, there was no easy alternative. The Philippines has reserves but lacks Indonesia's combination of scale, infrastructure, and government commitment to downstream processing. Canada and Australia have Class 1 nickel but not at the scale Indonesia provides. The world came to Indonesia — and built factories there.
Central Sulawesi · Flagship Belt and Road Initiative · The world's largest nickel processing complex
The Morowali Industrial Park in Central Sulawesi is the most visible expression of what Indonesia's nickel gambit actually built. Carved from rainforest in the decade following the 2014 export restrictions, it has become a vertically integrated ecosystem combining mining, smelting, stainless steel production, and battery materials processing — all on one site. The scale is extraordinary: tens of thousands of workers, dozens of processing facilities, its own captive coal-fired power plants, its own port infrastructure.
Tsingshan Holding Group, a Chinese private conglomerate, entered through a 2009 joint venture with Indonesia's Bintang Delapan Group. After the 2014 export restrictions, Tsingshan scaled rapidly — evolving production from nickel pig iron for stainless steel to battery-grade nickel chemicals over the following decade. Total Tsingshan investment in Indonesia: over $15 billion.
The IMIP has since become the template that Chinese firms replicated at Weda Bay Industrial Park in North Maluku and Pomalaa Industrial Park in South-East Sulawesi. Each follows the same model: anchor the park with mining and smelting, add stainless steel production, layer in HPAL facilities for battery materials, and begin moving toward cathode precursors and eventually battery cells. The vertical integration is comprehensive and the Chinese capital and technology is the dominant presence at every stage.
CATL — China's largest battery manufacturer and the world's dominant EV battery producer — has committed to a $6 billion consortium investment in an end-to-end nickel processing and battery project in Indonesia. If executed, this would complete the supply chain integration: from ore in the ground to battery cell ready for installation in a BYD or Tesla.
The strategic timing of Indonesia's nickel nationalisation was not accidental. The 2020 export ban coincided almost exactly with the acceleration of global electric vehicle adoption. EV battery demand for nickel was approximately 7% of global nickel consumption when the ban was implemented. The trajectory from 7% to the majority of nickel demand over the next decade was well-established in every credible demand model. Indonesia banned nickel ore exports precisely as the world was about to need more nickel than it had ever needed — and need it in a higher-value, more processed form.
The chemistry connection is specific. The dominant lithium-ion battery cathode chemistry used in long-range EVs is NMC — nickel manganese cobalt. Higher nickel content in NMC cathodes means higher energy density, which means longer range. Tesla, Volkswagen, Hyundai, and Ford have all established supply chain partnerships tied to Indonesian nickel access. LG Energy Solution and SK On — South Korea's dominant battery manufacturers — have substantial operations in Indonesia. The leverage that Indonesia's export ban created manifests in these partnerships as technology sharing requirements, domestic content mandates, and preferential treatment for investors committing to full value chain integration.
The HPAL process — high-pressure acid leaching — is the critical technology that converts Indonesia's Class 2 laterite nickel deposits into the Mixed Hydroxide Precipitate that eventually becomes battery-grade nickel sulphate. As of mid-2025, Indonesia had nine HPAL facilities in various stages of operation, construction, and feasibility study. Each facility costs $1–3 billion to construct. Together, they represent the infrastructure layer that allows Indonesian nickel to enter the EV battery supply chain at the high-value end — not just the cheap end.
The success — partial but real — of the nickel export ban has given Indonesia's policymakers confidence in what they call "downstreaming": using export restrictions on raw materials to force domestic value-added processing. The nickel ban is now the template being applied across Indonesia's mineral endowment.
Bauxite: Indonesia banned raw bauxite exports in June 2023, following the nickel playbook. Bauxite is the raw material for aluminium — another critical input to EV manufacturing, renewable energy infrastructure, and aerospace. The EU has filed another WTO case. Indonesia is following the same playbook, expecting the same outcome.
Copper and cobalt: Export restriction frameworks are being developed for both. Cobalt — a critical battery material where Indonesia has significant reserves — is particularly strategic. If Indonesia captures cobalt processing in the same way it captured nickel processing, the concentration of battery supply chain infrastructure in the archipelago becomes even more pronounced.
The geopolitical stakes are now explicit. The United States, through the Inflation Reduction Act's critical minerals provisions, is trying to build supply chains that exclude China. Indonesia's nickel industry is predominantly Chinese-owned and Chinese-operated. IRA-compliant supply chains cannot easily access Indonesian nickel processed by Chinese companies. This creates a specific tension: Indonesia has the mineral, the US has the market, and China has the processing. The resolution of that triangle will shape the geography of the global EV industry for the next decade.
Indonesia's nickel ban is simultaneously one of the most successful resource nationalist policies in modern history and a cautionary tale about who captures the value when foreign capital does the processing. The ban worked: it forced investment, built industrial parks, created processing capacity, and established Indonesia as a supply chain anchor rather than a commodity exporter. The Lowy Institute is right that Indonesia exceeded the expectations of international observers for downstreaming in nickel.
But the paradox identified by The Diplomat is also real: most of the processed NPI, ferronickel, and MHP are exported to China rather than supplying domestic industrialisation. Indonesian resources, processed by Chinese capital using Chinese technology, serving Chinese battery manufacturers — which then sell batteries to the world. Indonesia is higher in the value chain than it was before the ban. But the value-added margin is still predominantly captured by Chinese firms. Growth in the nickel industry has not translated into significant local job creation, poverty reduction, or government revenues at the scale the policy rhetoric implied.
The LFP threat is the most underappreciated strategic risk. Indonesia's entire downstream nickel strategy is predicated on the world continuing to prefer nickel-rich NMC batteries for EVs. BYD — now the world's largest EV company — has demonstrated that LFP batteries can deliver competitive range at significantly lower cost and without nickel. If the EV market converges on LFP as the dominant chemistry, the 300–400× value multiplication that made Indonesia's gambit compelling becomes significantly less relevant. Indonesia is betting on nickel. The battery industry is becoming less certain that it needs it.
