Argentina's libertarian president since December 2023, an economist known for his chainsaw-wielding campaign to slash the state.
See it on the Geopolitics map →The picture
Born in 1970, Milei was a TV economist and self-described anarcho-capitalist before winning the 2023 runoff with about 56%. He cut public spending by more than a quarter in real terms, cut tens of thousands of state jobs, ended many price controls and produced Argentina's first budget surpluses in over a decade. Monthly inflation fell from about 25% to around 2%. Poverty rose at first, then fell below its pre-Milei level. His party won the October 2025 midterms with about 41%.
Why it matters
He is a global icon of the populist right and Trump's closest Latin American ally, testing whether shock therapy can survive democratic politics.
Record
INDEC inflation and poverty data, IMF reviews and election results; critics cite falling real pensions and public wages, and scandals such as the 2025 $LIBRA crypto affair.
What to watch
Whether gains last once the peso floats freely, and whether scandals and social strain erode support before the 2027 presidential election.

▸Javier Milei leads ArgentinaFact
The relationship
Milei governs through decrees, vetoes and a congressional bloc enlarged after his party's October 2025 midterm win. His 'chainsaw' austerity, deregulation under minister Federico Sturzenegger and IMF-backed currency reforms have reshaped Argentina's economy and politics.
Since when and why
Buenos Aires; won the November 19, 2023 runoff against Sergio Massa, about 56% to 44%; inaugurated December 10, 2023.
How we know
Official election results, his December 2023 mega-decree (DNU 70/2023), INDEC economic data and IMF program documents.
What to watch
Whether Argentina's institutions lock in his reforms, or a future government reverses them as earlier reform waves were reversed.
▸Javier Milei won a $20B lifeline from Donald TrumpFact
The relationship
When Argentina's peso slid before the October 2025 midterms, Trump's Treasury signed a $20 billion currency swap with Argentina's central bank and bought pesos directly. Trump tied the help to Milei's success at the polls; Milei's win calmed markets.
Since when and why
Washington and Buenos Aires, September–October 2025; Treasury Secretary Scott Bessent announced the support, and the swap was signed October 20, 2025.
How we know
Treasury and Argentine central bank statements; Treasury later said the roughly $2.5 billion Argentina drew had been repaid in early 2026.
What to watch
Critics in both countries called it a political bailout risking US taxpayer money; supporters say it cheaply stabilized an ally. Whether it sets a precedent is debated.
