Weekly inflation was virtually unchanged in the third week of May. Consumer prices rose 0.75% WoW, broadly in line with the previous week’s revised 0.77%. The headline print remained stable, suggesting no further acceleration in the weekly pace despite firmer readings in core and seasonal prices. On a running basis, inflation is tracking at 2.8% MoM, while the annual rate stands at 34% YoY.
Component dynamics were mixed in the third week of May, with core and seasonal prices accelerating, while regulated prices slowed further. Core inflation came in at 1.02% WoW, up from the previous week’s revised 0.93%, while seasonal items rose 1% WoW, above the prior week’s 0.89%. Regulated prices increased just 0.14% WoW, down from 0.41% in the previous week. As a result, the softer regulated print helped offset stronger core and seasonal dynamics, keeping headline inflation broadly unchanged.
