US August headline CPI rose 0.4% MoM, matching expectations and marking the largest monthly increase since May; YoY inflation was 3.5%, also in line and unchanged from July. Core services inflation accelerated, but a rebound in crude oil and refined-product prices drove a pronounced rise in the CPI energy subindex. The move mirrors yesterday's PPI print, where higher fuel costs pushed wholesale inflation higher.
