Will lithium carbonate spot price average below $10,000/tonne for Q3 and Q4 2026?

Current lithium carbonate battery-grade prices are in the $10-12K/tonne range, already near the $10K threshold. However, sustained averages BELOW $10K for two consecutive quarters requires prices to drop further from current levels and stay there. EV demand continues growing globally, China's battery production is expanding, and supply discipline is improving as marginal producers curtail output. The current price range appears to be near a floor supported by marginal cost of production. While prices could dip below $10K temporarily, a sustained two-quarter average below that threshold would require a significant demand shock or massive supply expansion.

The 80% price crash from $80K to $10-12K reflects massive oversupply from Chinese and Australian production. While marginal costs provide some floor, the market remains oversupplied. New DLE projects and brine expansions in South America continue to add supply. If Chinese EV subsidy phase-outs reduce demand growth, or if sodium-ion batteries gain share for low-end EVs, lithium demand growth could slow while supply grows. The two-quarter sustained average requirement makes this harder than a spot price dip, but the supply overhang is real. Current prices sitting at $10-12K means a relatively small decline pushes below the threshold.

Commodity price forecasting is inherently uncertain. The current $10-12K range is near the threshold, making this question sensitive to relatively small movements. On one hand, multiple lithium miners have curtailed production below $10K levels, creating a natural price floor. On the other hand, Chinese refiners continue to hold inventory and new projects are still ramping. The DOE's own investment in LAC and other domestic projects presupposes long-term price recovery. I weight the structural demand growth from EV adoption as the stronger factor, suggesting prices more likely stabilize above $10K than sustain below it for two full quarters.

Prices at $10-12K are dangerously close to the threshold. The lithium market has been in oversupply for over two years. While some marginal producers have cut output, the major brine and hard rock operations in Australia and South America continue at scale. China's LFP battery dominance reduces lithium intensity per kWh. The resolution requires BOTH Q3 and Q4 averages below $10K — a sustained condition that becomes more likely if the oversupply persists through summer 2026. However, supply cuts should start biting by H2 2026, and EV adoption in Europe and US provides demand support.

The $10K level approximates the marginal cost of production for many operations. Extended time below this level would force additional mine closures, naturally supporting prices. The requirement for two consecutive quarter averages below $10K is demanding. While spot prices may briefly dip below, a sustained six-month average requires structural demand destruction that is unlikely given the ongoing EV transition. The bigger risk is prices remaining in the $10-14K doldrums rather than collapsing below $10K.

Commodity markets are notoriously difficult to forecast. The lithium market specifically is influenced by Chinese inventory management, EV subsidy policies across multiple countries, and battery chemistry evolution. Current prices near the threshold create genuine uncertainty. The analysis context notes that Thacker Pass economics were modeled during the boom — but the question isn't about LAC's project economics, it's about where lithium trades. Supply discipline and demand growth suggest prices more likely hover in the $10-15K range than sustain below $10K, but the proximity to the threshold prevents a confident assessment.

Lithium prices have stabilized in the $10-12K range. Major producer curtailments below $10K create a cost floor. EV demand continues to grow. Two consecutive quarters below $10K would require both supply growth and demand contraction — unlikely given EV adoption trends. More likely prices stay in $10-15K range.

Oversupply persists. Chinese refiners hold large inventories. New supply from Australia and South America continues ramping. Sodium-ion batteries may reduce lithium demand for entry-level EVs. The proximity of current prices to the $10K threshold makes this genuinely uncertain — a 10-15% decline from current levels would trigger it.

The marginal cost floor near $10K is the strongest signal. Producers cannot sustain output at prices below their cash costs for extended periods. While temporary dips below $10K are possible, a sustained six-month average requires structural market change. EV adoption growth provides demand support.
