Argentinian President, Javier Milei’s libertarian experiment is faltering. His hold on power is increasingly reliant on unpredictable US support. Milei, who recently claimed a significant midterm victory, has been backed extensively by Donald Trump. Trump has threatened that if Milei loses, US generosity towards Argentina will decline. To stabilize financial volatility that could threaten Milei’s position, Washington has provided a $20bn currency swap line to the government. The US treasury has also directly intervened, purchasing over a billion dollars of pesos to halt the currency’s rapid depreciation.
