Overview
After bouts of volatility over the past three years, lithium experienced a pronounced recovery in 2026. Prices more than doubled from last years troughs, and Bernstein characterizes the move as a "mid-cycle recovery," driven by tightening supplies and resilient battery-sector demand that may push prices higher into 2027 rather than prompting an imminent rollover.
Why this matters
Lithium is a foundational input for lithium-ion batteries used in electric vehicles and grid-scale energy storage. As such, swings in lithium prices affect a wide set of market participants - from mining and battery producers to automakers and renewable energy developers - and can influence project economics across those sectors.
Price trajectory and recent moves
Bernstein notes that lithium carbonate prices recovered from roughly $8,000 per tonne in mid-2025 to about $20,000-$25,000 at present. Prices briefly reached $30,000 in May before easing as some of the previously idled supply returned to the market. Those restarts provided temporary relief, but the brokerage contends they are unlikely to keep pace with ongoing demand growth.
Demand dynamics
The most notable surprise has come from energy storage systems (ESS), not electric vehicles. Bernstein reports lithium demand rose roughly 32% year to date, outstripping supply growth of about 24%. Within that demand mix, ESS demand surged nearly 100%, while EV demand expanded by a more modest 9%. This divergence has materially reduced inventories.
Inventory and supply balance
Inventory metrics underline the tightening. Bernstein estimates lithium inventories have fallen to roughly 20 days of supply - a level the brokerage associates with stronger pricing as buyers compete for scarcer material. Supply faces structural constraints as well. Mining firms reduced capital expenditure over the prior two-year period after prices fell from the 2022 peak, and new projects generally take around three years from final investment decision to first production.
Although Bernstein acknowledges that about 200,000 tonnes of previously curtailed capacity could gradually restart, it expects capacity additions to slow after 2026, elevating the risk of a supply deficit in 2027.
Demand resilience versus higher prices
Importantly, Bernstein argues that higher lithium prices are unlikely to significantly damage battery demand. The brokerage points out that battery costs have declined substantially over the past two years, which allows both energy storage developers and EV manufacturers to tolerate lithium prices in the $30,000-$35,000 per tonne range without materially undermining project economics.
Updated forecasts
Reflecting its market assessment, Bernstein raised its average lithium carbonate price forecast to about $25,000 per tonne for 2026, up from $21,000 previously. For 2027, it increased the forecast to $32,500 per tonne from a prior $25,000. Its long-term estimate remains at $16,000 per tonne, on the view that supply will ultimately catch up to demand over a longer horizon.
Conclusion
The brokerage concludes that a combination of tightened inventories, reduced mine investment, and accelerating battery demand suggests the current recovery has additional room to run. Consequently, Bernstein sees a higher probability that lithium prices will peak closer to 2027 rather than in the current year.
Key takeaways
- Lithium carbonate prices have climbed from roughly $8,000 per tonne in mid-2025 to about $20,000-$25,000 today, with a brief spike to $30,000 in May.
- Demand is outpacing supply - year-to-date demand growth of about 32% versus supply growth near 24% - led by a nearly 100% surge in energy storage system demand while EV demand rose roughly 9%.
- Bernstein raised its forecasts to $25,000 per tonne for 2026 and $32,500 per tonne for 2027, keeping a long-term price of $16,000 per tonne.
Risks and uncertainties
- Restarted, previously curtailed capacity - estimated at roughly 200,000 tonnes - may provide temporary supply relief, but may not be sufficient to match demand growth in 2027, increasing supply-deficit risk for mining and battery sectors.
- Mining capital expenditure cuts in the prior two years mean new projects typically require around three years from final investment decision to production, delaying meaningful supply additions and creating timing risk for downstream industries.
- Inventories have fallen to about 20 days of supply, a low level that heightens price sensitivity and could amplify volatility for miners, battery makers, automakers, and energy-storage developers if demand or supply assumptions change.
