Argentina publishes its September inflation figure on Tuesday 13 October 2026, and the calendar forecast points to a monthly reading near 2%. That would be a step up from 1.7% in August, the lowest in 14 months.
What We Know
INDEC, Argentina’s national statistics institute, is scheduled to publish September consumer prices on Tuesday 13 October 2026 at 16:00 Buenos Aires time (19:00 GMT). The date comes from INDEC’s release calendar, and the time from the RT economic calendar.
Monday 12 October 2026 is a public holiday in Argentina, the Day of Respect for Cultural Diversity. The data therefore arrives right after a long weekend.
The RT calendar forecasts monthly inflation of 2.0%, against 1.7% in August. It also forecasts annual inflation of 34%.
What the Numbers Look Like
In August, INDEC reported monthly inflation of 1.7%, the lowest monthly reading since June 2025, a span of 14 months. July had come in at 2.1%.
Core inflation, which strips out the most volatile prices, was 1.8% in August. Regulated prices rose 2.2%, while seasonal prices fell 0.9%.
The biggest rise among spending groups was housing, water, electricity, gas and other fuels at 2.8%. Education followed at 2.5%.
Cumulative inflation reached 21.3% in the first eight months of 2026. Any reading near 2.0% for September would add to that total.

What Is Not Known
It is not known whether the September figure will match the 2.0% forecast, because forecasts are estimates and the release can differ. The calendar projection is also not an official INDEC view.
It is also unclear which spending groups will drive the September result. Housing and education led the August rise, so they are natural groups to watch.
What It Means for US Readers and Investors
Argentine assets listed in New York, including American depositary receipts (ADRs) such as YPF, can react to inflation news. A reading above forecast could raise fresh questions about the peso.
Our earlier reports show how Argentina inflation fell to 1.7% in August after Argentina inflation ticked up to 2.1% in July. The September figure will show whether that cooling continues.
A reading near 1.7% would suggest that price growth is still slowing. A reading of 2.1% or higher would suggest that the August low was not the start of a lasting trend.
