BUENOS AIRES—The self-styled anarcho-capitalist who won Argentina’s presidency on Sunday plans to ditch his nation’s peso and adopt the U.S. dollar as the national currency.   

President-elect Javier Milei’s top campaign proposal was aimed at eradicating rampant inflation that has for decades ravaged Latin America’s third-biggest economy by removing the battered national currency from circulation and stripping the central bank of its power to print money. Uncontrolled money-printing to cover public expenditures, economists say, has fueled 143% inflation, one of the world’s highest.
