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.
