SQM — The Atacama Brine Lithium Cycle

Sociedad Química y Minera de Chile (SQM) operates the world’s lowest-cost lithium production from the Atacama brine in Chile, with production costs below $4,000/t — making it profitable across virtually all market conditions. This cost advantage creates exceptional leverage in lithium bull markets, and survival capacity in downturns that eliminate higher-cost competitors.

The Atacama Cost Advantage

SQM’s Atacama operations produce lithium carbonate at under $4,000/t versus Albemarle’s $8,000–10,000/t and Australian hard rock producers at $12,000–15,000/t. At lithium’s current price of approximately $12,000/t, SQM generates strong margins where peers struggle. This makes SQM the “Aramco of lithium” — the lowest-cost swing producer that sets the floor for the whole industry.

The 2020–2022 Cycle: +567% in 20 Months

SQM fell to $17 in March 2020 as lithium prices hit $6,500/t. Its low cost base meant it remained profitable even at cycle trough. As EV demand accelerated and lithium prices surged toward $84,000/t, SQM’s earnings leverage was exceptional. By November 2021, SQM reached $113 — a +567% return over 20 months, the highest of any major lithium producer.

The Chilean Political Risk

SQM operates under a Chilean state contract for Atacama brine extraction. Chile’s 2022 constitutional reform attempt and subsequent lithium nationalisation debate created political risk that compressed SQM’s valuation. President Boric’s decision to create a state lithium company (with SQM retaining a private partnership role) resolved the worst-case scenario but introduces ongoing regulatory uncertainty.

Key Risks

Chilean political risk remains the primary discount factor for SQM. Water rights disputes in the Atacama — the world’s driest desert — are intensifying as lithium extraction and indigenous communities compete for scarce water resources. Chinese overcapacity suppressing prices is SQM’s main market risk. SQM also has fertilizer (potassium nitrate, iodine) operations that add diversification but complexity.
