Inflation in Argentina has hit 161%. Its economy is shrinking, in part because of a ruinous drought. In the past five years, its currency has lost about 90% of its value against the U.S. dollar. Its debts, including $45 billion that it owes the International Monetary Fund, are suffocating. One in four Argentinians lives in poverty.
Whether Milei succeeds will depend partly on details that have yet to be worked out and compromises that need to be made to win political support for his program. He commands a fragile base in the Argentine Congress, with his party ranking a distant third in the number of seats it holds.
But the critical question, economists say, is this: Will the Argentinian people - who gave Milei, a libertarian economist, nearly 56% of the vote in a runoff election last month - continue to back his plan once real economic pain inevitably sets in?
"They appear to have the sense that the population has given them a mandate to do all these painful measures,'' said Monica de Bolle, senior fellow at the Peterson Institute for International Economics. "The moment (Argentinians) start seeing their empty pockets and nothing is really improving because it's going to take time ... people will get impatient, and that support can evaporate.''
What makes his challenge so difficult is that Milei's plan seems certain to make people's lives worse long before they get better. Reduced government subsidies mean that Argentinians will pay more for electricity and transportation. A devalued peso will make imports more expensive. The annual inflation rate, de Bolle said, could roughly double to 300%.
