For years the nickel bull case was clean: batteries want high-purity class 1 nickel, class 1 is scarce and expensive to make, therefore the price goes up. It was a good story. Indonesia took it out behind the smelter and shot it.

Two metals, one ticker

The first thing to get straight, because almost everyone gets it wrong: nickel is two markets.

  • Class 2 — ferronickel and nickel pig iron (NPI), the stuff that feeds stainless steel.
  • Class 1 — the high-purity metal and sulphate that batteries actually want.

For a long time those were almost separate worlds, and the battery story was a class 1 story. Then Indonesia did two things at once: it banned raw ore exports to force processing onshore, and it let in a tidal wave of mostly-Chinese capital to build NPI, matte and HPAL capacity on top of its giant laterite resource. The result is that Indonesia learned to turn cheap class 2 feed into battery-grade class 1 product — and did it at a cost that the rest of the world simply cannot match.

The cost curve got flattened on purpose

This is the part to sit with. Indonesia didn't out-compete the Western producers by accident or by being marginally cleverer. It did it as deliberate industrial policy: use the ore ban as leverage, import the capital and the technology, build the whole midstream domestically, and own the cost curve. Western producers going into care-and-maintenance is not a bug of that strategy — it's the strategy working. BHP ($BHP) mothballed its Nickel West operations in Western Australia; the class-1 sulphide incumbents like Vale ($VALE) and Glencore ($GLEN), who make exactly the clean nickel batteries say they want, watched their economics undercut by a flood of Indonesian product they can't price against.

The lowest-cost tonne wins, and Indonesia decided to manufacture the lowest-cost tonne by decree.

What we'll be watching

  • The class 1 / class 2 spread. When the market panics, it tends to forget they're different qualities. The spread is where the truth lives.
  • HPAL ramps and their real costs. High-pressure acid leach is brutal, capital-hungry chemistry. The nameplate capacity is not the achieved capacity. We'll believe the tonnes when they ship.
  • The ESG and tariff backlash. Western buyers want non-Indonesian, lower-footprint nickel. Wanting it and paying the premium for it are different things, and so far the premium keeps losing.

But Jakarta is now turning the screw the other way

Here's the 2026 update the permabears missed: the same government that engineered the glut is now throttling it. Indonesia cut its 2026 ore quota (RKAB) hard — to roughly 270 million wet tonnes from about 375 million in 2025 — moved to annual rather than multi-year approvals, and signalled a stop to new NPI and HPAL plants. The global balance has flipped from surplus toward deficit, and LME nickel rallied on the order of 37% from its late-December 2025 low into the spring. Indonesia didn't lose control of the price. It's now managing it up as deliberately as it once managed it down.

The honest read: the low-cost structure Indonesia built is permanent; the flood is not. A "permanent buyer's market" was always the wrong frame. The right one — the lowest-cost tonne still wins, and the government that owns the lowest-cost tonne now sets the price in both directions. For BHP, Vale and the other care-and-maintenance casualties, the question is whether this rally is a restart signal or just Jakarta defending its own margin.
