Overview
- INDEC begins using a revised Consumer Price Index in January 2026 that reweights the basket based on the 2017/18 household spending survey and broadens price coverage.
- Applying the new index lifts the recalculated cumulative inflation since President Javier Milei took office to roughly 270%, up from about 259% under the prior methodology.
- Private surveys forecast December 2025 inflation between 2.3% and 2.7%, placing the annual rate near 31%, which would be the lowest since 2017.
- The overhaul increases the weight of housing, transport and communications, reduces health, and expands the sample from about 320,000 to 500,000 prices with more price informants.
- Analysts highlight meat as a key driver of recent monthly food moves and debate whether fiscal and monetary choices in 2026 will sustain disinflation or keep price pressures elevated.
