POSCO Holdings' lithium business in Argentina has finally reached a significant milestone, achieving its first monthly profit in March 2026.
This isn't just a simple story of rising tides lifting all boats. While the rebound in lithium prices during the first quarter certainly helped, the true narrative lies in POSCO's strategic groundwork that transformed the very meaning of that price recovery. The company has built a resilient structure designed to withstand the market's inherent volatility.
Let's break down the causal chain. First, the external environment became more favorable. Lithium carbonate prices (CIF CJK) jumped from around $14,500/t in January to $21,000/t by the end of March. At the same time, Argentina's new government began implementing investment-friendly policies like the RIGI (Regime for the Incentive of Large Investments), reducing political risk and improving the project's financial outlook.
Second, POSCO enhanced its operational efficiency. The Sal de Oro plant's operating rate surpassed 70%, a critical threshold for achieving economies of scale. This increase in production volume directly lowered the fixed cost per ton, contributing significantly to breaking even.
Third, and most importantly, the company de-risked its business model through strategic partnerships. The long-term supply agreement with SK On secures a stable sales channel, reducing exposure to volatile spot market prices. Furthermore, the joint venture with Australia's Mineral Resources gives POSCO rights to 30% of the spodumene ore from two mines. This creates a dual supply chain of both brine from Argentina and hard rock ore from Australia, allowing for optimized raw material costs and hedging against supply disruptions from a single source.
In essence, these strategic moves—securing long-term buyers and diversifying raw material sources—have turned lithium price fluctuations from an uncontrollable external threat into a manageable variable. The recent profitability is not a temporary result of a market upswing, but a testament to a well-executed, long-term strategy focused on building a sustainable and robust business.
