6% to 60%.
Control not included.

A supply base rebuilt on purpose, in a decade.

Less than 6 percent. That was Indonesia’s share of global mined nickel in 2014, the year it first moved to ban the export of raw ore. A decade later the figure is above 60 percent. No major commodity has had its supply base rebuilt so quickly or concentrated so tightly in one country: Indonesian mine output rose roughly tenfold in the ten years to 2023, and the value of the country’s nickel-related exports tracked the same curve — from about $1.1bn in 2017, when it still shipped mostly unprocessed ore, to more than $30bn by 2022.

This was not an accident of geology. It was policy. The 2009 Mining Law mandated domestic processing; the ban bit for nickel in 2014, was relaxed, then reimposed in full in January 2020. Stop exporting rocks, force the smelters to come to the ore, capture the value that used to accrue offshore. Rio Tinto and other majors balked and left. Chinese capital did the opposite and doubled down. By any conventional metric of industrial policy, Indonesia won. The uncomfortable part is what winning bought.

Controlling supply is not controlling price — and neither is capturing value.

The same policy that gave Indonesia the tonnes flooded the market until it broke the price. Nickel fell from $27,466 a tonne in January 2023 to $16,429 a year later, a drop of 40 percent, and touched a four-year low near $13,900 by April 2025 — close to two-thirds below its March 2022 short-squeeze peak above $48,000. Indonesian refined output had turned a market in deficit into a structural surplus and held it there: eighteen consecutive monthly surpluses into late 2023, LME inventories climbing from below 40,000 tonnes to past 250,000. Indonesia had become nickel’s swing producer, and its first casualty was nickel itself.

Its second casualty was everyone else’s mine. In February 2024 BHP booked a $3.5bn pre-tax impairment on its Western Australian nickel division; by July it had suspended the business and named a glut of low-cost, Chinese-backed Indonesian supply as the reason. Australian output fell from over 150,000 tonnes to around 60,000. A producer large enough to set a commodity’s price is large enough to destroy it — and a cost base among the world’s lowest leaves Indonesian supply almost indifferent to the falls that force higher-cost rivals to close.

Sovereignty over the ore, it emerges, is not sovereignty over the value chain that processes it.

This is where the value question sharpens. Roughly $30bn of Chinese investment built the machine the policy summoned. Chinese firms have constructed more than 90 percent of the country’s nickel smelters; Tsingshan and Jiangsu Delong alone account for over 70 percent of refining capacity, and Chinese-controlled companies produce roughly 80 percent of Indonesia’s battery-grade nickel. Indonesia captured the tonnage, the export line and tens of thousands of jobs. What it captured less of was the margin, the process technology and the offtake, which sit largely with the partners who financed and operate the plants.

The legal coda is its own lesson in the limits of control. The European Union challenged the export ban at the WTO and won: in November 2022 a dispute panel ruled the ban illegal. Indonesia appealed into a void — the WTO’s Appellate Body has been unable to function since 2019, after the United States blocked the appointment of judges, so the ruling sits unenforced. The rules-based trade system delivered a verdict it had no machinery to impose. For any resource nation weighing whether to copy the playbook, that unenforced ruling is the most instructive precedent of all.

Then there is the carbon. Battery-grade nickel from Indonesia’s laterite ore releases two to six times the CO₂ of the sulfide route mined in Canada, Russia or Australia, because the parks run on captive coal. “Green nickel,” produced to feed the EV transition, has become one of the most carbon-intensive forms of heavy industry on the planet — and the premium markets of that transition are now being wired to keep it out.

The cheapest tonne can be the least valuable one.

The decisive point for investors is commercial, though it is converging with the moral one. The US Inflation Reduction Act’s foreign-entity-of-concern rules disqualify any battery mineral more than 25 percent owned or controlled by a Chinese entity from the consumer EV credit — a test almost all Indonesian nickel fails. The EU’s carbon border levy entered its definitive phase in 2026, and its battery passport, demanding mine-level provenance and carbon data, arrives in 2027. Price is starting to depend on how a molecule was made and who made it, not merely on what it is.

Jakarta’s own response is the tell. Having built a Chinese-financed, coal-powered export machine, it is now trying to retrofit it for a Western market that is closing — pressing for a critical-minerals deal with Washington, nudging producers toward part-Western structures such as the Ford–Vale–Huayou joint venture, and floating an “OPEC of nickel” to defend the price it spent a decade destroying. The clearest beneficiaries of the saga may prove to be the Western sulfide projects, lower-carbon and outside the China supply chain, whose strategic value rises precisely because Indonesia made the alternative so cheap and so compromised.

Strip the story to its spine and it is one lesson in the difference between volume and value. A market you dominate can still dictate terms to you. The cheapest supply in the world is still worth only what the buyer of last resort will pay for it.
