President Javier Milei’s administration has prioritized fiscal austerity, peso devaluation, and a floating exchange rate backed by IMF programs and a $20 billion U.S. currency swap rather than official dollarization. No legislation has advanced to eliminate the peso or designate the dollar as sole legal tender, and reserves plus central-bank balance-sheet constraints remain unresolved. With the June 30, 2026, resolution date only days away, traders assign a 99 percent probability to “No” because the procedural and technical steps required for formal adoption cannot realistically be completed. The sole plausible shifts would involve an unforeseen last-minute executive decree or congressional vote that immediately pegs or replaces the currency—developments absent from current policy signals.
