Lithium Triangle Splits Three Ways as Milei Opens Argentina, Chile Nationalizes, Bolivia Stalls
Political shifts across South America's battery belt are creating divergent investment regimes just as EV demand reshapes global supply chains.
Argentina is accelerating lithium extraction under President Javier Milei’s deregulation push while Chile tightens state control and Bolivia’s political chaos leaves $3 billion in contracts unratified, fragmenting what was once a unified regional resource strategy.
The policy split comes as Buenos Aires Herald reports Argentina aims to expand capacity from 186,000 tonnes annually to 580,000 tonnes by securing $12.8 billion in new investment – a trajectory enabled by Milei’s RIGI incentive regime, which cuts corporate tax from 35% to 25%, guarantees 30-year regulatory stability, and allows external arbitration, according to MINING.COM. Rio Tinto plans to invest $2.5 billion in Argentina’s Rincon mine with 60,000 tonnes annual capacity, and that Lithium Argentina submitted applications for RIGI financing in December 2025.
Chile is pursuing the opposite approach. The country is moving toward partial state control through a Codelco-SQM partnership giving government majority stake, with President Boric requiring all new lithium contracts to operate as public-private partnerships, according to Catalyst. Only two companies – SQM and Albemarle – currently operate in Chile’s Salar de Atacama, with contracts expiring in 2030 and 2043 respectively, though Codelco and SQM have agreed to extend operations to 2060 with the state owning 50% plus one share, reports Baker Institute.
Chile’s March 1, 2026 government transition could influence regulatory streamlining, though constitutional lithium ownership provisions and the CEOL framework remain established by law rather than executive decree, according to Discovery Alert. Implementation has shown progress for existing Atacama projects, but it remains unclear how Chile will create a globally competitive industry with what seems like excessive state involvement, notes Columbia University’s Center on Global Energy Policy.
Bolivia’s Contracts in Limbo
Bolivia holds the region’s largest reserves but produces almost nothing. The country possesses 23 million tonnes – 20% of global reserves – yet makes up less than 1% of production, despite signing $2 billion in contracts with Chinese and Russian firms in 2024 and a $1.4 billion deal with CATL in 2023, reports Climate Change News.
Bolivia’s lithium contracts are “contracted but contested,” according to Mariano Machado of Verisk Maplecroft, who told MINING.COM they are investable for early-stage work but not yet bankable for large-scale project finance, as “Congress, courts and public pressure can still re-price deals midstream”. Russia’s ambassador to Bolivia stated the new center-right government under President Rodrigo Paz Pereira may revise terms of existing agreements, potentially hampering cooperation as the administration seeks to strengthen ties with the United States, according to Russia’s Pivot to Asia.
Bolivia’s state-run YLB produced 2,000 metric tons in 2024 with $15.6 million in revenues – less than 1% of Chile’s approximately 300,000 ton annual output, according to Discovery Alert. Bolivia’s lithium-rich brines contain high magnesium concentrations, making extraction significantly more expensive and technically complex than deposits in Chile and Argentina, the analysis notes.
Environmental Friction in Argentina
Milei’s extraction acceleration faces pushback. In 2024, Argentina’s Salar del Hombre regional court suspended issuance of new lithium mining permits due to concerns about water sources, allowing for a comprehensive environmental impact study, reports Mongabay. In Catamarca’s Hombre Muerto Salt Flat, more than 10 projects operate without cumulative environmental assessment, while the Fenix project has caused the drying of 5 km of the Trapiche river, an important freshwater source for indigenous communities, according to FARN.
The Lithium Triangle – encompassing salt flats across northwestern Argentina, southwestern Bolivia, and northern Chile – contains approximately 58% of global identified lithium resources. Traditional brine extraction pumps lithium-rich water into evaporation ponds, a process requiring 18-24 months. Direct Lithium Extraction (DLE) technologies can reduce this to weeks while lowering water consumption, but remain unproven at commercial scale in most operations.
In Argentina, attention has focused on water consumption and adverse impacts on human well-being and biodiversity, with critics pointing to insufficient local involvement in decision-making and government promotion of lithium with inadequate environmental information access, notes a Fundar analysis.
Battery Supply Chain Implications
The fragmentation creates supply uncertainty for manufacturers. China dominates nearly every step of the lithium-ion Battery Supply Chain, processing 60-70% of global lithium and producing about 75% of battery cells, with CATL holding roughly 38% market share and BYD 17%, according to Catalyst. China was responsible for 80% of global battery cell production in 2024 and has established near monopoly on battery components, supplying almost 85% of cathode active materials and over 90% of anode production, reports the International Energy Agency.
| Factor | Argentina | Chile | Bolivia |
|---|---|---|---|
| Corporate tax rate | 25% (RIGI projects) | Standard 27% | 25% |
| State ownership | Provincial variation | 51% minimum new projects | 51% constitutional requirement |
| Regulatory stability | 30-year RIGI guarantee | Contract-dependent | Under revision |
| External arbitration | Permitted (RIGI) | Limited | Restricted |
| Environmental approval | Provincial control | National oversight | State company led |
IDTechEx forecasts a 14.2% CAGR for lithium-ion demand over 2026-2036, while industry experts believe a surge in demand will outpace production, potentially creating a deficit as early as 2026, according to deVere Group. Lithium demand rose nearly 30% in 2024 alone, notes Catalyst.
Yet prices remain under pressure. Goldman Sachs initially predicted lithium carbonate averaging $13,250 per tonne in 2026, rising to $17,077 by 2028, but revised forecasts down to $8,900 per tonne average in September, according to deVere Group citing Reuters. Bolivia’s contracts assume prices of $27,280 per tonne, far above the current $10,000 market rate, raising feasibility questions, reports Deheza.
What to Watch
Three variables will determine whether the Triangle’s fragmentation creates opportunity or constraint. First, whether Chile’s new government post-March 1, 2026 streamlines or further complicates the CEOL approval process – contract submissions in March 2026 represent a crucial test of Chile’s ability to maintain constitutional oversight while reducing regulatory complexity. Second, Bolivia’s parliamentary decisions on the Chinese and Russian contracts, which span up to 42 years for CBC and 23.5 years for Uranium One, potentially producing 104,000 tonnes annually combined if ratified. Third, Argentina’s ability to secure skilled labor and infrastructure – railway privatization award decisions are slated for March 2026, with freight capacity expansion critical to export logistics.
Argentina’s National Mining Secretary Luis Lucero positioned the country as “the place to be” in the Lithium Triangle, noting “Bolivia has closed itself to investment” and “Chile has a different approach”, according to MINING.COM. Whether battery manufacturers can diversify supply chains or remain dependent on Chinese processing – which controls 60-70% of global lithium refining – will shape pricing power through 2030. The Triangle’s political divergence is creating three distinct investment regimes just as demand accelerates, turning what should be a unified regional advantage into a test of whether resource nationalism can coexist with supply chain security.
