What INDEC Will Publish
INDEC measures prices for a basket of goods and services in Argentina. It reports the monthly change and the change over 12 months. For August, it reported 1.7% for the month and 33.5% over 12 months, according to the series that ArgentinaDatos republishes.
The September figure is due on Tuesday 13 October 2026. the RT economic calendar lists the release at 19:00 UTC, which is 4 p.m. in Buenos Aires.
The month before, July, was 2.1%. Argentina’s monthly rate has moved between 1.7% and 2.1% in the last four months, so September will show whether the slowdown continues.
What Forecasters Expect
The central bank’s market survey, known as the REM, is an average of what economists expect. Its September edition, collected from 28 to 30 September, pointed to 1.9% for September prices.
the RT economic calendar shows a consensus of 2.0%. These are forecasts, and each forecaster builds its own basket.
Prediction markets give a similar picture. Polymarket traders put the most weight on a range of 1.9% to 2.1%. They also give about 29% to a lower range of 1.6% to 1.8%, and about 7% to 2.2% to 2.4%. The spread is a reminder that the result could land on either side of 2%.
What It Means for Your Budget
Prices in pesos rise every month, so the peso cost of living grows even when inflation slows. Take a monthly budget of ARS 1,000,000 (about US$651 at the official sell rate of 1,535). A 2% monthly rise adds ARS 20,000 (about US$13). A year at 33.5% adds ARS 335,000 (about US$218).
The effect in dollars depends on the exchange rate. If the dollar rate rises more slowly than prices, Argentina becomes more expensive for people who spend dollars. If the dollar rate rises faster, the opposite happens. Neither is fixed, and the central bank does not announce its path in advance.
If you pay rent or a contract in pesos, check how and when your contract adjusts. Many contracts name an index or a fixed monthly percentage, and the INDEC figure is one possible reference.
The Dollar Rates This Weekend
DolarApi shows the official Banco Nación rate at 1,485 pesos to buy and 1,535 to sell on Friday afternoon. The informal blue rate is 1,520 and 1,540. The CCL, the securities-based rate, is 1,605.5 and 1,606.6 as of Saturday evening. The wholesale rate was 1,508 and 1,517.
The official sell rate and the blue rate are within about 0.3% of each other. The CCL is about 4.7% higher. Country risk, the extra yield investors demand on Argentine dollar bonds, was 589 points on Friday 9 October, ArgentinaDatos reported.
What Is Not Known
We do not know the September figure. We also do not know how much of the move will come from food, from regulated prices such as transport and utilities, or from services. INDEC publishes that breakdown with the headline number, and we will use it when it is out.
The picture has two sides. Inflation is far below the levels of earlier years, but at 33.5% a year it still erodes savings held in pesos. A calm approach is to read the full release on Tuesday before changing a budget, a contract or a plan to move money.
