Alphacast High Frequency CPI - June 29th to July 5th 2026
Alphacast High Frequency CPI: Inflation was 0.59% WoW
Weekly inflation accelerated in the first July reading. Consumer prices rose 0.59% WoW, up from 0.09% in the previous week. On a running basis, monthly inflation eased to 1.6% MoM, from 1.9%, while the annual rate remained broadly stable at 33.2% YoY.
The weekly acceleration was mainly driven by regulated prices, which tend to show a seasonal pattern at the beginning of each month due to scheduled adjustments in services and other regulated items. Regulated prices rose 1.34% WoW, well above the previous week’s 0.08%, pushing their annual rate slightly higher to 36.2% YoY. Core inflation also accelerated, increasing 0.25% WoW, from 0.09% previously, although its monthly run rate continued to ease to 1.4% MoM. Seasonal prices rose 0.32% WoW, up from 0.12%, while their monthly pace declined to 1.2% MoM.
Overall, the first July reading showed a clear weekly rebound, mostly explained by the typical beginning-of-month adjustment in regulated prices. However, the monthly run rate continued to moderate, suggesting that the increase did not fully reverse the broader disinflation trend observed through June.
