The Incentive Regime for Large Investments (RIGI), the crown jewel of President Javier Milei’s economic deregulation, is no longer just an Argentine success story—it has become a strategic nightmare for neighboring Chile. As of May 2026, the massive influx of capital into Argentina’s mining and energy sectors has sent shockwaves across the Andes, with Chilean industry leaders warning that their country is losing its historical lead in the regional “investment race.”

The “Lost Decade” vs. 18 Months of Reform

The president of the Chilean Mining Chamber, Manuel Viera Flores, recently issued a blunt warning, stating that Chile is currently “a decade behind” in terms of fiscal stability and competitiveness. The contrast is stark: while Chile has spent years bogged down in regulatory “permisología” and shifting tax debates, Milei’s administration has managed to attract over $26 billion across 12 major projects in just 18 months.

  • Fiscal Stability: The RIGI offers a 30-year guarantee of tax, customs, and exchange rate stability—a horizon that Chile currently cannot match.

    The Lithium Shift: For decades, Chile was the undisputed leader in lithium. However, projections now indicate that Argentina will surpass Chile in lithium production within the next 5 to 8 years, thanks to a “smart investment” policy and clear rules of the game.

The “Kast” Government and the Search for a Chilean RIGI

The concern in Santiago is so profound that even with the recent administration of José Antonio Kast attempting to accelerate project approvals, the industry argues the pace is “not enough.” Chilean mining executives are now openly calling for their own version of the RIGI to prevent a mass exodus of capital toward Argentine soil.

 

“Seamos honestos: Chile perdió una década… Milei hizo en 18 meses lo que en Chile no hemos logrado en 10 años.” — Manuel Viera Flores, President of the Chilean Mining Chamber.

Strategic Sectors Under the Spotlight

The “investment rain” in Argentina isn’t just about lithium. The RIGI’s reach has expanded into:

  • Copper: High-altitude projects in the San Juan province are now competing directly for the same global capital that previously only looked at Chile.

  • Energy & Infrastructure: Offshore developments and new onshore hydrocarbon projects have been integrated into the regime, further diversifying Argentina’s export profile.

    Technology: The recent extension of the RIGI until 2027 also includes incentives for AI, robotics, and aerospace, positioning Argentina as a high-tech hub.

    A New Regional Standard

For President Milei, this regional tension is a validation of his “pro-market” axis. By slashing the state’s intervention and providing ironclad legal certainty, Argentina has transformed from a “pariah” into the new regional standard for large-scale investment. As Chile grapples with how to respond to this newfound competition, the message from the Casa Rosada is clear: freedom is the ultimate competitive advantage.
