Nickel's Two-Tier Market Fractures: NPI Glut in Indonesia Collides With LME Class 1 Deficit
2026-11-03, FP360 — The global nickel market has split into two violently diverging tiers: Indonesian nickel pig iron (NPI) is in surplus, pressuring prices, while LME Class 1 refined nickel sits in a 4.2% supply deficit due to battery-grade demand. This bifurcation is reshaping pricing dynamics, squeezing short sellers and creating a volatile arbitrage for traders.
Decoupling of NPI and Class 1 nickel intensifies, with LME nickel backwardation set to persist as supply deficits deepen.
LME Class 1 nickel backwardation widens, boosting cash-settled futures and battery-grade producers' margins.
NPI oversupply threatens to spill into Class 1 via new conversion capacity, capping upside for refined nickel.

- What Happened: Indonesia's NPI output hit a 12.4% year-over-year growth, driving the NPI discount to LME nickel to $1,800/tonne, while LME Class 1 stocks fell 4.2% to a four-year low of 41,000 tonnes, creating a tightness premium.
- Hidden Mechanism: The gap is not just about raw supply—it's a collateral story: LME warrant cancellations in Europe and Asia have surged as battery makers lock in Class 1 metal, while NPI is being hoarded by stainless steel mills anticipating a demand rebound.
- Capital Transmission: Liquidity is rotating from NPI-focused portfolios into Class 1-backed ETFs and mining equities with refined exposure, exacerbating the deficit and setting the stage for a short squeeze in nickel futures.
The Two-Tier Nickel Market: Why NPI Is Cheap and Class 1 Is Expensive
Nickel has become a tale of two markets. On one side, Indonesia's nickel pig iron (NPI) is flooding the stainless steel supply chain, with output climbing to 1.2 million tonnes in Q3 2026—up 12.4% from a year earlier. On the other, LME-registered Class 1 nickel, the high-purity metal needed for EV batteries, is in a 3.5% global supply deficit. This dichotomy has driven the NPI discount to LME nickel to $1,800/tonne, near its widest since 2023. For investors, the message is clear: nickel is no longer a single commodity—it's two, and the premium for battery-grade material is only going to grow as the energy transition accelerates.
Indonesia's NPI Glut: The Stainless Steel Steamroller
The story starts in Indonesia, where a wave of new smelters, many backed by Chinese capital, has turned the country into an NPI powerhouse. Total capacity now exceeds 1.5 million tonnes annually, thanks to supportive government policies and abundant laterite ore. But here's the catch: this supply is overwhelmingly low-grade NPI (8-12% nickel), suitable for stainless steel but not for EV batteries, which require Class 1 nickel (99.8% purity). As a result, the Indonesian surplus is depressing NPI prices and stainless steel costs, but it's not easing the tightness in the battery metal market. In fact, it's creating a headache for LME nickel bulls, who are seeing the global nickel inventory picture clouded by this non-deliverable supply.
Why LME Class 1 Nickel Is in Deficit: The Battery Demand Juggernaut
On the other side of the divide, Class 1 nickel supply is struggling to keep pace with demand from the EV and battery storage sectors. Global refined nickel production is forecast to rise only 3.1% in 2026, while demand is growing at 5.8%, according to the International Nickel Study Group. That's a 2.7% supply shortfall. The deficit is most acute in Europe and North America, where battery gigafactories are ramping up. LME inventories have fallen to 41,000 tonnes, the lowest since 2022, and the cash-3-month spread is in a $125/tonne backwardation—a sign of physical tightness. This is why LME nickel has held above $22,500/tonne despite the NPI glut. For battery and stainless steel buyers, the message is simple: don't expect the NPI surplus to rescue you; the two markets are decoupling.
Positioning & Liquidity Map: Who Is Trapped?
On the LME, speculative net long positioning in nickel has risen to 32% of open interest, the highest since 2023, according to CFTC data. This suggests that funds are betting on the Class 1 deficit, but they are vulnerable to a sudden influx of NPI-derived nickel. Short sellers, primarily in the NPI market, are under pressure as NPI prices have stabilized near $14,000/tonne, but they are not yet squeezed. The marginal buyer is battery-grade consumers, who are paying a premium of $1,800/tonne for Class 1 over NPI. If LME stocks continue to fall, a short squeeze could send the cash-3-month spread to $200/tonne, forcing shorts to cover. Alternatively, if Indonesian smelters start producing more Class 1, the premium could collapse.
