Indonesia banned nickel ore exports and built an industry on top

In January 2020 Indonesia stopped exporting nickel ore. Not taxed it, not licensed it: stopped it, requiring every tonne dug on Sulawesi and Halmahera to be processed in the country before anything left port¹. Five years later the results read like the brochure for resource nationalism. Smelters in operation went from two in 2014 to 59 by 2025. Exports of ferronickel and nickel alloy, under $1 billion a year before the policy, reached about $15 billion in 2023 and $13-14 billion in 2024. Indonesia's share of world mined nickel went from under a third to more than 60%¹².

Every country with a mineral and a grievance has noticed. The DRC's cobalt quotas, Chile's lithium nationalisation, and half the export restrictions catalogued by the OECD in the past decade cite the Indonesian precedent by name or by shape: Indonesia is one of 53 countries that restricted mineral exports between 2009 and 2023¹. What follows is both columns of the account, because the policy that built the industry also built its problems, and the second half of the story is quoted less than the first.

The ban took two attempts

Nickel is old business here. A Dutch geologist identified the deposits at Pomalaa in Southeast Sulawesi in the early 1900s; PT Vale's predecessors began exploring in the 1920s, and large-scale mining ran from the 1970s, exporting ore and doing little else to it¹. For a century the laterite hills were a quarry for other countries' furnaces, which is precisely the arrangement the export bans were written to end.

The first try failed instructively. A 2014 ban under a 2009 mining law cut Indonesia's share of world production from 32% in 2013 to 8.3% in 2015, because the smelters the ban assumed did not exist yet; the government blinked in 2017 and allowed low-grade ore out again¹. What made the 2020 reinstatement stick was the investment that arrived in between, and the investor was specific: Chinese stainless-steel and battery-materials groups, led by Tsingshan, whose Morowali industrial park became the backbone of the sector, financed by Chinese state banks¹. Central Sulawesi alone now hosts 35 smelters.

The lesson other resource states take is usually 'ban exports'. The operative lesson is narrower: a ban works when someone is ready to build the processing the ban strands demand into, at a scale that matters, quickly. Indonesia had a neighbour with idle capital, steel overcapacity at home, and a strategic interest in owning the battery supply chain. Congo's cobalt and Chile's lithium wait on the same question with less obvious suitors.

What it earned

The macroeconomic column is real. Processed nickel runs at roughly 5% of Indonesia's total exports, which reached $282.9 billion in 2025; the country has run a trade surplus every month since May 2020, 68 consecutive months, totalling $41 billion in 2025 after $32 billion in 2024¹. Value has climbed the chain on schedule: by 2024 nickel sulphate, the battery-grade product, earned $3.04 a kilogramme against ferronickel's $1.45, and the battery consortiums have followed, with China's Huayou investing $8.8 billion by April 2025 and CATL and partners committing to an integrated battery ecosystem. The capture is real but partial: mining, smelting, and intermediates are onshore at scale, precursor and cell plants are arriving, and cathode design, cell IP, and the end customers remain elsewhere¹.

The regional column is real too. In the smelter provinces, Central Sulawesi and North Maluku, formal employment in mining surged, unemployment across the 13 smelter regencies fell from 4.46% in 2014 to 3.19% in 2023, and the local tax office collected a record $1 billion in 2023¹. Smelter-belt wages average around $220 a month against a provincial average near $165. These are the numbers a development ministry likes to display; per worker, though, they are small numbers, which is the first hint of the other column.

What it cost

Start with the price, because Indonesia crashed it. World-scale supply growth this fast, 2.0 million tonnes in 2023 and 2.2 million in 2024 from Indonesia alone, cut the LME nickel price to roughly half its 2022 peak; through 2025 it traded between $11,833 and $13,514 a tonne³. At those levels the higher-cost half of the world's industry is underwater: mines mothballed in Australia and New Caledonia, and Indonesian producers themselves cutting output and laying off workers¹. Winning 60% of a market by halving its price is a strategy with a built-in second act.

The environmental bill is the least contested part. The dominant smelter technology, rotary kiln electric furnace lines, 35 of the 59, runs on captive coal power built alongside the parks, and laterite mining strips forested hillsides; the nickel that goes into vehicles marketed as green is among the most carbon- and land-intensive on earth¹. The EU took the trade half to the WTO in 2021 and won; Indonesia has appealed into the void of the paralysed appellate body and changed nothing¹. The legal defeat cost the policy no tonnage, an outcome other would-be banners have filed away.

The chemistry moved mid-policy

The ban was designed around stainless steel, which is where ferronickel goes and where most Indonesian nickel still ends up. The battery era arrived mid-build and changed the target: electric vehicles need high-purity class 1 nickel and nickel sulphate, which laterite ore reaches through high-pressure acid leaching, a technology with a history of blown budgets that Chinese operators have, to the industry's surprise, made work at scale in Indonesia. That is what the sulphate premium in the export data measures, and it is why the battery majors are building at the parks rather than merely buying from them¹.

It also concentrates a new risk. Batteries are a moving target: the lithium-iron-phosphate chemistries taking share at the affordable end of the vehicle market contain no nickel at all. Indonesia's downstream bet pays best in a world that keeps choosing nickel-rich cells for range, and pays worst if the cheap end of the market, which is the big end, finishes its migration to iron. A state that synchronised its industrial policy to one cathode recipe has tied its second decade to electrochemists it does not employ.

Now the state wants the price back

The 2026 turn is the Indonesian state discovering what OPEC learned in the 1980s: market share and price are bought with the same currency. The mining ministry set 2026 ore quotas, the RKAB system, at 260-270 million wet tonnes against 379 million approved for 2025, a cut of roughly a third⁴. Markets believed it: LME nickel rose from just above $14,000 in mid-December to more than $17,000 by 11 February 2026⁴. Having built the world's dominant supply, Indonesia is now rationing it, which is the same move Congo made with cobalt quotas three months earlier, applied from a far stronger position: Indonesia rations feedstock into smelters it hosts, so the value the cut creates lands onshore either way.

Would-be imitators should read the fine print first. The policy's exportable core was never the ban; it was the sequencing and the leverage. Indonesia already held enough of world supply that stranding its ore stranded the customers, not itself, and it priced entry to its market in exactly the currency it wanted: smelters on Indonesian soil. It has since extended the template to bauxite and squeezed copper concentrate the same way. A country holding 10% of a commodity that copies the headline move gets the 2014 result, an 8.3% share and a retreat, not the 2020 one. Market power is the prerequisite of the policy, not its product.

Watch three numbers through 2026 and 2027. Whether the RKAB cut holds when smelter margins compress, because the parks employ the voters the ministry answers to. Whether nickel sulphate's premium over ferronickel widens, because that spread is the whole case for the battery-chain build-out¹. And what share of new smelting investment arrives from anywhere other than China, because a policy sold as national independence has so far diversified Indonesia's customers less than its creditors. Ferronickel and alloy exports still go overwhelmingly to China¹, which means the ban rerouted the dependency rather than ending it: the ore stays home, the value chain runs through Chinese-owned parks, and the finished intermediates cross the same water the raw ore used to. Sovereignty over the rock was the easy half; whether Indonesia gains the same hold over the industry sitting on it is the next decade's question.
