Argentina’s consumer price index (CPI) edged up in September 2026, with month‑over‑month inflation rising to 1.9%, up from 1.7% recorded in August. The latest data, updated on 13 October 2026, indicate a modest acceleration in price growth after a month of relative moderation.
On a month‑over‑month basis, September’s reading shows that inflationary pressures have strengthened slightly compared with the prior period. In August 2026, the CPI increase of 1.7% represented the change versus July, while the September 1.9% reflects the change from August, underscoring a renewed, if measured, pickup in consumer prices.
The shift may raise questions among market participants and policymakers about the durability of any disinflationary trend, as even a small acceleration can be significant in an economy closely watched for inflation dynamics. Investors will now be looking to upcoming data to gauge whether September marks the start of a new upward drift in prices or a temporary bump in Argentina’s inflation path.
