Inflation showed acceleration on a weekly basis. Consumer prices rose by 0.4% WoW, a much higher pace compared to the revised 0.1% WoW gain from the previous week. On a monthly scale, inflation stood at 2.3% as last week. Consequently, the annual rate was kept at 30.4% YoY, slightly inferior to the earlier adjusted 30.5% YoY.
During the reference week, core, seasonal and regulated prices accelerated. Core prices increased 0.47% WoW, higher than the revised 0.13% WoW registered in the prior week. On a monthly scale, core prices advanced 2.6% MoM, equal than the earlier week. Seasonal products rose 0.53% WoW, above the previous 0.16%, and their MoM pace moved up to 2.1% from 2.0%. Regulated prices rose 0.32% WoW, and their monthly gain reached also 1.7%, superior to the 1.6% 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.
