Argentina’s October Inflation Rises to 2.2% Amid Temporary Price Pressures, While Core Inflation Drops to Multi-Year Low: Eugenio Rodolfo Sanabria Reporter / Updated : 2026-11-15 12:27:19

Argentina’s headline inflation ticked up to 2.2% in October, marking the second consecutive monthly increase after September’s 1.9% reading, according to data published Thursday by the national statistics agency, INDEC.

While the headline figure represents the highest monthly rate since April—when inflation hit 2.6%—President Javier Milei’s administration received a positive signal as core inflation declined to 1.5%, down from 1.7% the previous month. This marks one of the lowest core inflation readings of Milei’s presidency and the lowest level overall since November 2017, when it stood at 1.3%.

Year-on-year inflation reached 33.1%, while cumulative inflation for the first ten months of 2026 stood at 26.3%.

Driving Factors: Headline vs. Core Inflation

The divergence between headline and core inflation was largely driven by categories excluded from the core index, such as seasonal and government-regulated prices.

Seasonal Prices: Rose 5.5%, heavily influenced by spikes in the costs of vegetables, tubers, and legumes.
Regulated Prices: Increased by 2.9%, propelled by upward adjustments in gas and motor fuel tariffs.

Analysts and government officials pointed to structural and regulatory shifts as key drivers. Economy Minister Luis Caputo noted on social media that the monthly outcome was impacted by modifications to the "Cold Zone Regime"—a system providing subsidized natural gas tariffs to specific colder regions across the country.

This policy shift heavily influenced the housing, water, electricity, gas, and other fuels category, which registered the highest monthly increase at 4.2%, with regional variations ranging from -2.2% to +11.1%. The recreation and culture category saw the second-largest increase at 3.3%. Conversely, the smallest national price increases were recorded in alcoholic beverages and tobacco (0.8%) and education (1.3%).

Market Reactions and Outlook

Despite the encouraging drop in core inflation, headline figures missed market expectations, which had centered around 1.8%.

Experts remain cautious about the trajectory of price stabilization. Analysts at the brokerage firm Puente suggested that temporary factors, including the continued fallout from the Cold Zone Regime adjustments, might linger into November before headline inflation fully converges with the lower core rate.

Guido Zack, Director of Economics at the Fundar think tank, highlighted that while the drop in core inflation is a welcome development, heightened macroeconomic volatility means the 1.5% figure may not yet establish a permanent new baseline. He concluded that Argentina continues to face persistent hurdles in consistently pushing monthly inflation below the 2% threshold.
