At least from the data, the Milley reforms are effective.

In the first half of the 20th century, Argentina's inflation was generally moderate, making it the South American Paris with stable economy.
It was only after Peronism came to power in the 1940s, implementing state intervention and welfare expansion, that a core vicious inflation cycle gradually formed, concentrated over the past 50 years. In 2023, inflation soared to 211.4%.
Milley implemented full dollarization, completely locking the Argentine government’s ability to print money with the US dollar, effectively curing decades of hyperinflation, while also tying the country’s credit to the US and attracting foreign investment, completely overturning the old economic model.
This is a double-edged sword; the cost is the complete abandonment of monetary sovereignty, making it impossible to use exchange rates. Monetary policy to respond to economic crises is now fully tied to the US economy. Once the US raises interest rates, Argentina will face direct pressure.
