Alphacast High Frequency CPI - September 29th to October 7th 2025
Alphacast High Frequency CPI: Inflation was 1% WoW
Inflation showed acceleration on a weekly basis. Consumer prices rose by 1% WoW, a much higher pace compared to the revised 0.4% WoW gain from the previous week. On a monthly scale, inflation stood at 2.1%, mantaining its pace relative to previous week. Consequently, the annual rate rose to 30.5% YoY, slightly superior to the earlier adjusted 29.8% YoY.
During the reference week, core, seasonal and regulated prices sped up. Core prices increased 0.76% WoW, higher than the revised 0.31% WoW registered in the prior week. On a monthly scale, core prices advanced 1.9% MoM, lower than the earlier 2.2%. Seasonal products rose 0.74% WoW, above the previous 0.35%, and their MoM pace lowered to 1.9% from 2.1%. Regulated prices rose 1.6% WoW, and their monthly gain reached also 2.4%, superior to the 2.1% posted in the prior week.
Note: This week, we are sharing a shortened version of the report as we are currently in the midst of migrating and upgrading our pricing system. Very soon, the new system will go live and enable us to publish core inflation indices with daily updates, which will be made directly available in Alphacast’s datasets. This enhancement marks a significant step toward greater accuracy and frequency in inflation tracking, further facilitating real-time analysis. Thank you for joining us in this transformation process. Any feedback or suggestions are more than welcome.
