Argentina’s annual inflation rate sped past 211% in December, official data showed on Thursday, hitting the highest level since the early 1990s as new libertarian President Javier Milei seeks to head off hyperinflation with tough austerity measures. Argentina’s monthly inflation rate also hit 25.5% in the month, slightly below forecasts, after a sharp devaluation of the peso currency last month after Milei’s government took office on Dec. 10, pledging to get inflation under control.
