BUENOS AIRES —
Argentina's President Javier Milei saw his popularity ratings rebound sharply in October, a poll on Monday showed, bolstering the libertarian whose pro-market reforms have driven markets to record highs since winning a shock election last year.
A closely watched poll from the local Torcuato Di Tella University showed Milei's approval rating jump 12% after it slid in September because of tensions around pension reforms.
The South American grains producer is battling triple-digit inflation and a recession, but former pundit Milei has managed to boost confidence in markets with tough spending cuts while largely keeping voters onside with his straight-talking style.
Inflation, still in triple digits on an annual basis, has come down sharply each month, foreign currency reserve levels are being rebuilt and his government has turned around a deep fiscal deficit. Poverty levels, however, have risen sharply.
A separate survey from consultancy Aresco showed the approval rating of Milei's government bouncing to 52.5% in October from 49.6% a month before, which it attributed to improving economic indicators.
