Argentina's Senate Passes New Investment Regime and Carbon Market

Argentina's Senate has approved a new investment regime known as the RIIR, along with the creation of a carbon market, according to La Nación. Security Minister Patricia Bullrich celebrated the passage and said the measure would attract "opportunities to invest and grow," the outlet reported.

The approval was recorded in La Nación's live coverage of President Javier Milei's measures on Friday, 30 October 2026. La Nueva Provincia also reported that the Senate backed a regime aimed at further supporting investment.

According to Ambito, the government achieved a double objective in the Senate: it passed investment promotion bills and kept its political allies satisfied. Diario La Capital de Mar del Plata reported that fishing was added to the incentives project for new investments at the request of Abad.

The material reviewed does not specify the vote count, the terms of the regime, or how the carbon market would operate. Those details were not available in the reporting summarized here.

The package is part of the Milei administration's legislative agenda, and its passage gives the government a win in the upper chamber while accommodating allied sectors. La Nación's coverage framed the outcome as a celebration for Bullrich, who linked the regime directly to future investment.

What to watch next: how the government implements the new investment regime and the carbon market, and whether further changes are made as the measures move toward application.
