The deficit that Indonesia built
Through 2025, every major nickel forecaster — ING, CRU, Project Blue, SMM — projected a market surplus of 200,000–280,000 tonnes for 2026 (FACT: ING Think, December 8, 2025). ING's outlook was explicit: "Nickel still capped by surplus," with a 261,000-tonne surplus forecast and a $15,250/t average price call. The World Bank's October 2025 Commodity Markets Outlook projected $15,500/t for 2026. Consensus Economics' January 2026 survey of 21 forecasters produced a December 2026 mean of just $16,000/t, with a range of $14,500–$19,000/t (FACT: PricePedia, February 2, 2026).
Then Indonesia changed the math. The INSG's April 2026 meetings in Lisbon produced a radically different picture: world primary nickel output of 3.715Mt against usage of 3.747Mt, yielding a deficit of 32,000 tonnes (FACT: INSG Press Release, April 22, 2026). That is a 315,000-tonne swing from the 283,000-tonne surplus recorded for 2025 — the largest single-year balance reversal in the nickel market since the 2008 financial crisis.
What follows is Rzzro's three-scenario framework for H2 2026 — not a single point forecast, but a probabilistic decision matrix calibrated to what a nickel buyer should actually do in each scenario.
Supply foundation
CONFIRMED: Indonesia's RKAB quota cut is the single most important supply event of 2026. The INSG reported that Indonesia's approved nickel ore mining quota for 2026 was set at a significantly lower level than 2025 (FACT: INSG, April 22, 2026). Each permit holder can submit one amendment request, subject to government supply-demand assessment. This is not a hard cap — it is a managed scarcity mechanism. Separately, a revised benchmark price mechanism (HPM) effective April 15 raised base prices across all ore grades and, for the first time, incorporated cobalt, iron, and chromium into the pricing formula (FACT: INSG, April 22, 2026). The HPM change alone represents a structural cost increase for every tonne of Indonesian nickel, regardless of quota.
PROJECTED: The Philippines will act as a swing supplier, but cannot replace Indonesia. Philippine laterite ore exports to China rose approximately 15% in 2025 as Chinese NPI processors sought alternatives (FACT: SMM, various). However, Philippine ore grades are lower and logistics costs are higher. At Indonesia's new HPM floor, Philippine ore loses its price advantage. The net effect is that the seaborne nickel ore market is structurally tighter even before any quota enforcement.
CONFIRMED: LME inventories remain elevated but the trajectory matters more than the level. LME nickel stocks stood at about 250,000 tonnes as of mid-May 2026 — the highest in more than four years (FACT: ING Think, December 2025; LME data). The Class 1 surplus has been absorbed by exchange warehouses, with Chinese-origin cathode making up 70% of available tonnage by October 2025 (up from 50% in January). Indonesian cathode exports to the LME rose nearly 80% in the first three quarters of 2025 (FACT: ING, citing LME country of origin data). The key metric for H2 2026 is not the absolute stock level but the draw rate: if LME stocks begin falling on the INSG deficit signal, the backwardation that has been absent for two years could return rapidly.
CONFIRMED: NPI curtailments are accelerating outside Indonesia. Global nickel producers outside Indonesia are closing mines, scrapping development projects, and selling assets as low prices make ex-Indonesia supply uneconomic (FACT: ING, December 2025). This includes operations in New Caledonia, Australia, and Brazil. These curtailments are structural — they will not snap back even if prices recover to $20,000/t.
Demand foundation
CONFIRMED: Stainless steel is 60%+ of nickel demand and growth is sluggish. The stainless sector recorded growth in 2025 and is projected to expand further in 2026 (FACT: INSG, April 22, 2026). But manufacturing activity in key economies is declining, and the stainless market is heavily dependent on China's construction and industrial sectors. China's May 19 macro data missed expectations across retail sales, industrial production, and fixed asset investment. Without a Chinese stimulus program, stainless growth in 2026 will struggle to exceed 2-3%.
CONFIRMED: Battery demand is growing — but not for Class 1 nickel. The battery sector is expanding at a slower pace than anticipated, driven by two structural forces: LFP chemistry dominance and PHEV substitution. In China, NMC's market share in EV batteries fell to 18% in the first nine months of 2025 from 25% in 2024 (FACT: ING, December 2025; ICCSino data). LFP cells cost about 25% less than NMC, and that cost advantage is driving global market share gains. In the US, the removal of EV subsidies under the July 2025 "One Big Beautiful Bill Act" eliminated the $7,500 federal tax credit, and October 2025 sales data already showed a sharp decline (FACT: ING, December 2025). The nickel sulfate premium over LME Class 1 metal — a key battery demand indicator — remains compressed, reflecting the market's recognition that the battery boom is nickel-class-specific.
CONFIRMED: The nickel sulfate vs. Class 1 price spread tells a dual-market story. Battery-grade nickel (nickel sulfate, MHP) trades on a fundamentally different supply-demand equation than Class 1 metal delivered to the LME. The HPAL capacity expansion in Indonesia is primarily targeting the battery supply chain, not the LME-deliverable Class 1 market. This means a surplus in Class 1 inventories — reflected in LME stock levels — can coexist with tightening in the battery-grade market. For a buyer, the relevant price is whichever grade your supply chain consumes.
Rzzro forecast position
The consensus is still catching up to the Indonesia-driven reality. Goldman Sachs raised its 2026 average nickel price forecast from $17,200/t to $18,500/t, citing tightening Indonesia supply (FACT: Reuters/TradingView, May 2026). The World Bank's April 2026 forecast of approximately $17,000/t for 2026 still reflects pre-quota assumptions and is likely too low. PricePedia's February 2026 forecast of $16,000/t for 2026 was explicitly based on pre-quota, pre-HPM data. Rzzro believes the market is in the early stages of repricing Indonesia risk, and the direction of that repricing is unambiguously higher.
The INSG deficit of 32kt is small in absolute terms — 0.9% of forecast 2026 usage of 3.747Mt. But it represents a directional change from years of surplus. The nickel market has gone from structurally oversupplied to precariously balanced, with all of the swing factors — Indonesia quota enforcement, HPAL ramp, EV adoption — pointing to further tightening.
Three scenarios for H2 2026
$18,000–22,000/t
Activation: Indonesia's approved ~250Mt RKAB quota holds. LME stocks begin a gradual draw from ~250kt as the INSG deficit filters through. Global stainless demand grows 3-4%, in line with modest GDP growth. Battery-grade demand continues its gradual expansion, HPAL projects ramp on schedule.
Narrative — Q3 2026: LME nickel averages $18,000–20,000/t. The quota effects begin showing in Indonesian ore availability; NPI prices in China edge higher. LME stocks draw slowly — 10,000–15,000 tonnes per month — as Chinese cathode exports to the LME moderate. Physical premiums in Europe and North America widen modestly. The nickel sulfate spread remains stable but does not compress further.
Narrative — Q4 2026: LME nickel averages $19,000–22,000/t. The INSG deficit becomes visible in exchange inventories. A moderate backwardation develops on the LME for nearby months. Indonesian HPAL capacity reaches nameplate but the incremental tonne goes to batteries, not LME Class 1. Physical premiums in Europe widen to $200–300/t over LME cash. Procurement teams that locked H2 coverage early are vindicated; those relying on spot are paying up.
Key triggers to watch:
- LME on-warrant stocks falling below 200,000 tonnes — accelerates deficit pricing
- Any Indonesian RKAB amendment denial — bullish signal
- Nickel sulfate premium rising above $500/t — battery demand tightening
- Chinese stainless output above 35Mt annualized run rate — demand upside
Performance: Q3 avg ~$19,000/t · Q4 avg ~$20,500/t
Procurement playbook: Lock 40% of projected H2 volume at $18,000–19,000/t using LME forwards. Float 30% with a $16,000 floor purchased via put options. Keep 30% for spot purchases to capture any bear-driven dip. On any move below $16,000/t (unlikely in this scenario), increase forward coverage to 60%. Budget assumption: $18,500/t.
$22,000–28,000/t
Activation: Further Indonesia quota constraints — either the initial RKAB cut is deeper than reported, or Jakarta denies most amendment requests. A supply disruption at Morowali or Weda Bay (the world's largest nickel mine) from environmental enforcement or social conflict. EV battery demand accelerates unexpectedly — possibly a technology breakthrough in high-nickel chemistries or a policy reversal in a major market.
Narrative — Q3 2026: LME nickel averages $22,000–24,000/t. The first signal is a sharp drop in LME stocks as traders and consumers scramble for physical metal. Indonesian NPI export volumes fall, and Chinese stainless mills bid up domestic NPI prices. The INSG deficit projection of 32kt proves too conservative as supply disruptions compound. Physical premiums in Europe hit $350–500/t.
Narrative — Q4 2026: LME nickel averages $24,000–28,000/t. A sustained backwardation develops. LME stocks fall below 150,000 tonnes. Battery-grade premiums explode as HPAL capacity proves insufficient to meet demand. The market enters a "buy at any price" phase for consumptive buyers without coverage. Suppliers invoke force majeure on fixed-price contracts.
Key triggers to watch:
- RKAB approved tonnage below 200Mt — severe supply constraint
- Any mine shutdown in Indonesia — immediate price spike
- LME on-warrant stocks below 150,000 tonnes — backwardation trigger
- Nickel sulfate premium above $1,000/t — battery panic
- Global PMI above 52 for two consecutive months — demand acceleration
Performance: Q3 avg ~$23,000/t · Q4 avg ~$26,000/t
Procurement playbook: Shift immediately to supply assurance. Pre-cover critical volumes regardless of price. Use cost-plus contracts with suppliers rather than fixed-price to avoid force majeure risk. If LME stocks fall below 150,000 tonnes, buy any available physical at market. Consider physical inventory buffer of 2–3 months' consumption. Hedging with caps/collars is secondary to securing the physical tonne.
$14,000–18,000/t
Activation: Indonesia relaxes quotas — approving substantial upward amendments in response to price pressure from miners and local governments. A global recession triggered by the Middle East conflict escalation reduces stainless and general manufacturing demand. New HPAL capacity adds supply faster than anticipated, overwhelming battery-grade demand growth. LFP chemistry adoption accelerates beyond expectations.
Narrative — Q3 2026: LME nickel averages $14,000–16,000/t. The first signal is a rebound in LME stocks as Indonesian cathode exports resume their upward trajectory. NPI prices in China decline as ore availability improves. The INSG deficit forecast is revised back to surplus in the October meetings. Physical premiums collapse as buyers step back.
Narrative — Q4 2026: LME nickel averages $15,000–18,000/t. A modest recovery from Q3 lows as some supply adjusts, but the structural surplus narrative returns. LME stocks exceed 300,000 tonnes. The contango widens, making storage economics attractive for financiers. Buyers with fixed-price forward coverage find themselves well above market.
Key triggers to watch:
- Indonesia RKAB amendment approvals exceeding 300Mt total
- Global stainless output drop >5% year-on-year
- LME stocks exceeding 300,000 tonnes
- Global PMI below 48 for two consecutive months
- LFP market share above 75% of new EV batteries
Performance: Q3 avg ~$15,000/t · Q4 avg ~$16,500/t
Procurement playbook: Minimize forward commitments. Buy spot or short-dated index-linked. Avoid building inventory — let suppliers carry it. Pressure suppliers on premium transparency and alloy surcharge breakdowns. If prices dip below $14,500/t, begin layering in modest forward coverage for 2027. Budget assumption: $16,000/t.
