A little bit of old news, but it seems useful to see what various indicators show, month-on-month annualized. Chained, trimmed and sticky price inflation are all lower than headline:

Trimmed inflation is up, but much lower than overall, suggesting that while broad based, it’s some high components pushing up overall. Lower sticky price inflation means a lot of the variation is coming in from flexible price movements, so that downward movement in headline could be reflected in overall noticeably.

Sticky price core inflation is lower than headline — although not much lower. That’s because energy costs are one of the big flexible price categories.

Looking forward, one notes that gasoline prices have fallen in tandem with oil prices.

Source: FRED.

By the week ending July 11, the price of gasoline had fallen to 4.646, down 7.2% from week-ending-June 13th. Taken literally, with a 3.75% weight on gasoline, then that implies a quarter percentage point reduction in July m/m inflation, or over 3 ppts on an annualized basis, not taking into account other ways in which gasoline prices feed into overall prices.
