Lithium prices nearly doubled in Q1 2026 as the oversupply narrative collapsed

Summary

Battery-grade Lithium carbonate prices nearly doubled in six weeks: from approximately $13,433/t in early December 2025 to $26,278/t by late January 2026, a 95% increase, as buyers absorbed a structural demand shift and the 2024-2025 "oversupply" narrative collapsed. The surge was driven by two concurrent factors: the 51% year-on-year growth in battery energy storage demand in 2025, powered by AI-era grid expansion, and a tightening of Chinese lithium inventory following two years of destocking. Forecast houses remain split. Morgan Stanley and UBS project a 2026 deficit of 80,000t and 22,000t lithium carbonate equivalent (LCE) respectively. S&P Global models a 109,000t LCE surplus, and Wood Mackenzie also forecasts a surplus. Canaccord Genuity projects deficit conditions persisting through 2035. Argentina is the primary source of new supply, with direct lithium extraction (DLE) projects (Rio Tinto Rincon, Eramet Centenario, POSCO Sal de Oro) ramping output; the country is projected to deliver over 60% supply growth in 2026.

The split

The deficit camp (Canaccord, Morgan Stanley) argues the 2024-2025 oversupply was an inventory artefact from Chinese cathode manufacturers destocking, not a fundamental surplus; underlying demand has consistently grown and new project timelines slip. The surplus camp (S&P, Wood Mackenzie) points to real inventory levels and notes DLE projects in Argentina plus Chilean SQM-Codelco volume targets that, if met, create excess supply. The Q1 price surge is interpreted differently: bulls read it as confirmation of structural tightness; bears read it as a speculative overshoot that partially corrected in Q2. DLE technology, initially expected to be a 2026 supply breakthrough, has underdelivered relative to pre-2025 projections: Rio Tinto Rincon, Eramet and POSCO all experienced execution challenges, and DLE's 2026 contribution remains marginal.

By the numbers

• $13,433/t, battery-grade lithium carbonate price in early December 2025.
• $26,278/t, battery-grade lithium carbonate by late January 2026 (a 95% increase in six weeks).
• 51%, year-on-year growth in battery energy storage demand in 2025.
• ~20%, share of global battery demand from energy storage (grid + stationary) by end-2025.
• 80,000t LCE, Morgan Stanley's projected 2026 deficit (most bearish on supply).
• 109,000t LCE, S&P Global's projected 2026 surplus (most bullish on supply).

• 60%, projected Argentina supply growth in 2026 (largest percentage increase of any country).

Why it matters

Lithium is the definitional battery metal, irreplaceable in all mainstream EV and grid-storage chemistries (LFP, NMC, NCA). The 2024-2025 price crash, which pushed lithium below the cost of production for many mines, resulted in project deferrals, mine suspensions and a structural underinvestment that will constrain supply into the late 2020s. The 2026 Q1 price re-rating signals that the supply pipeline is not keeping pace with demand even at current EV penetration rates. The split between forecast houses reflects genuine uncertainty about DLE commercialisation timelines, the Chile JV's execution risk, and Bolivia's stranded reserves. Whoever is right, Western automakers and battery manufacturers that locked in multi-year offtake during the 2024-2025 trough have secured a material cost advantage.

What to watch

• Argentine DLE project ramp rates (Rio Tinto Rincon, Eramet Centenario, POSCO Sal de Oro) in H2 2026.
• Chinese lithium inventory levels as the primary leading indicator of whether the surplus or deficit thesis is correct.
• Battery energy storage demand growth in H2 2026: if AI infrastructure build-out maintains 50%+ annual growth, the deficit case strengthens.
• Lithium price in Q3 2026: whether the Q1 surge was a structural re-rating or a speculative overshoot.
