Editor's note: This is the second installment of a two-part series on the impacts of Argentina's potential dollarization under Javier Milei, should he win the country's presidential election. The first part, which can be found here , examines the way dollarization affects emerging economies, and the second analyzes challenges specific to Argentina. In Argentina, presidential candidate Javier Milei — a libertarian who has promised to overhaul the country's economic system, including by replacing the Argentine peso with the U.S. dollar — is currently leading the polls ahead of the Oct. 22 presidential election , fueling fears that the country could soon be ''dollarized.'' In light of Milei's expected victory, it's important to look at the unique challenges dollarization would pose in Argentina, given the country's history of hyperinflation, economic crises and political instability.
