Three South American governments are trying to rewrite the economics of the clean-energy boom. Instead of shipping raw lithium abroad and letting someone else pocket the difference, Chile, Argentina and Brazil are each racing to hold on to a bigger share of refining, battery-grade processing and factory jobs — a bet worth billions that could decide whether the "lithium triangle" turns into a lasting source of wealth or just another commodity story.
-
Global lithium demand is projected to climb 353% between 2024 and 2040, and refined battery metals already sell for three to four times the price of raw ore — the core reason all three countries are chasing processing capacity, not just mines.
- The three governments are testing opposite playbooks: Chile keeps the state in majority control through Codelco, Argentina is luring foreign capital with 30-year tax guarantees, and Brazil is leaning on niobium and rare earths to diversify beyond lithium.
-
The payoff is already visible — Chile alone controlled 46% of the world's refined-lithium exports in 2025 — but so is the risk: Latin America absorbed more mining-related arbitration claims than any other region last year.
