Critical Minerals Market May 2026: Prices & Outlook

The critical minerals market May 2026 opens with nickel at a 23-month high, lithium at a three-month peak, and copper near an all-time record — a broad-based rally driven by simultaneous supply shocks, structural deficit data, and accelerating demand signals from EVs and data centres.

May 2026 Critical Minerals Price Summary

Nickel Hits 23-Month High on Three Concurrent Shocks

Nickel touched $19,450/tonne on 28 April 2026 — its highest level since mid-2024 — before settling back to approximately $19,270/tonne. The move was driven by three simultaneous developments, each independently capable of tightening the market.

Indonesia revised its nickel ore benchmark pricing formula during April, establishing a structurally higher cost floor for the world’s dominant nickel-producing nation. Separately, Middle East conflict disrupted sulphur shipments to China, raising processing costs for high-pressure acid leach (HPAL) operations — the dominant technology for converting Indonesian laterite ore into battery-grade nickel. Indonesian stainless steel producers suspended offers ahead of anticipated price increases.

The third driver is the most consequential for medium-term pricing. The International Nickel Study Group (INSG) projects a global primary nickel deficit of 32,200 tonnes in 2026 — the first deficit since 2021. The gap between current spot and the $20,000–$22,000/tonne threshold at which idled Western production becomes economic has narrowed materially.

Lithium Extends Recovery to Three-Month High

Lithium carbonate reached approximately CNY 175,000/tonne (around $24,100/tonne) in late April — a three-month high and a gain of roughly 50% from the CNY 130,000–135,000/tonne year-open. The move has multiple demand-side catalysts.

BYD revised its 2026 overseas sales target upward to 1.5 million units from 1.3 million, adding a direct volume signal to the market. Beijing committed to 180GW of EV charging capacity by 2027. Data centre operators are emerging as an incremental battery demand source — a structural shift that, if it sustains, expands the addressable market beyond automotive. The Zimbabwe export ban on lithium concentrates remains in force, constraining raw material supply. CME lithium carbonate futures recorded consecutive monthly trading volume records in both March and April, signalling growing institutional participation.

Fastmarkets notes caution: the rally has moved ahead of physical fundamentals, and thin spot liquidity leaves the market vulnerable to sharp corrections. SMM price assessments were suspended during China’s Labour Day holiday (1–5 May); the next readings are due the week of 6 May. See the lithium price tracker for current spot data.

Copper Surges to Record Before Five-Session Pullback

Copper hit a record $6.12/lb on COMEX on 22 April 2026 before retreating to approximately $5.91/lb by month-end — still up 4.8% from the $5.64/lb April open, equivalent to around $13,026/tonne on an LME basis.

Two supply-side shocks drove the record. Middle East conflict disrupted sulphur shipments to China, prompting Chinese authorities to restrict sulphuric acid exports — a critical input for copper refining in Chile, where approximately 50% of processing capacity was affected. Simultaneously, the Grasberg mine in Indonesia, one of the world’s largest copper operations, declared force majeure following a fatal mudslide.

On the demand side, data centre construction activity continues to underpin the medium-term outlook, and China’s manufacturing PMI beat expectations in April — a constructive signal for industrial metals more broadly. See the copper price tracker for ongoing spot data, and the top copper mining companies for the supply-side landscape.

Cobalt Holds Firm — Stockpile Watch

Cobalt remained flat month-on-month for the third consecutive period at $56,290/tonne (LME cash, 29 April 2026), consolidating at elevated levels as the market awaits confirmation of procurement timelines from the US strategic stockpile programme.

The US $12 billion strategic stockpile initiative names cobalt as a priority material — a demand signal that has underpinned market sentiment without yet translating into confirmed purchasing activity. The structural supply deficit remains intact. For historical price context and the supply-demand outlook, see the cobalt price tracker. Production rankings are covered in the top cobalt producers article.

Rare Earths: NdPr at 160% Year-to-Date

NdPr metal (mixed praseodymium-neodymium) reached $136.7–$139.6/kg by 30 April 2026 according to the China Rare Earth Industry Association (CRIA) domestic price index, which stood at 273.7 (2010=100). The gain from the January open of approximately $53/kg represents a year-to-date move of around 160%.

The rally has spread from NdPr into the heavy rare earth complex: dysprosium oxide reached $886.7–$895.4/kg and terbium oxide $728.6–$757.7/kg. The breadth of the move — spanning both light and heavy rare earths — is a structural rather than speculative signal. The MP Materials DoD contract, which established a $110/kg NdPr price floor for US government procurement, is covered in our MP Materials DoD contract profile.

Graphite — Stable, May Data Pending

Graphite showed no material month-on-month movement heading into May. The last available SMM benchmark for China flake graphite (-194 mesh, nationwide average) was approximately $346.64/tonne as of 1 April 2026; May assessments were suspended during the Labour Day holiday and are expected to resume the week of 6 May. Artificial graphite mid-end EV battery material was assessed at approximately $3,419.64/tonne on the same date.

Fastmarkets launched two new Chinese domestic flake graphite price assessments in April 2026, covering 94% carbon content in -100 mesh and +80 mesh grades on an ex-works China basis — a sign of growing price transparency in a market that has historically been opaque. Updated pricing will be reflected in our graphite price tracker when May SMM data is published.

Cross-Commodity Context: Shared Risk Factors

Two macro themes cut across multiple metals in April. The Middle East conflict is simultaneously raising HPAL processing costs for nickel and curtailing Chilean copper refining capacity via the same sulphur disruption pathway — an unusual instance of a single geopolitical event tightening two structurally different markets at once.

Indonesian policy is a second cross-commodity risk: the nickel ore benchmark revision establishes a structurally higher cost floor that could also affect cobalt production given the geographic overlap of nickel-cobalt laterite deposits. Dollar strength remained a headwind for USD-priced metals through much of April.
