FX.co ★ Argentina’s Inflation Eases Slightly as September CPI Slips to 33.5% YoY

Argentina’s consumer price inflation showed a marginal slowdown in September 2026, with the year-over-year CPI easing to 33.5%, down from 33.7% in August 2026. The latest data, updated on 13 October 2026, indicate that price pressures remain extremely elevated, but the pace of annual increases has inched lower.

Both the current and previous readings are based on year-over-year comparisons, measuring how prices in each month evolved relative to the same month a year earlier. The modest decline in September suggests that, while inflationary momentum may be losing a fraction of its intensity, Argentina continues to grapple with entrenched high inflation that remains a central challenge for households, businesses, and policymakers alike.
