Why traders watch CPI
CPI lands before PCE, the Fed's preferred inflation gauge, every month, so it is the first hard read on whether inflation is cooling or heating up, and the Fed's next move turns on that. A hotter print pushes rate cuts further out and is bearish for Treasuries, with the 2-year moving most. Traders read the month-over-month change to the second decimal, because 0.2% a month compounds to about 2.4% a year and 0.3% to about 3.7%.
Headline CPI and core CPI
Headline CPI counts everything in the basket. Core CPI takes out food and energy, which swing with the weather and oil, so it shows the underlying trend better, and markets usually trade the core figure. Both come out in the same release. The year-over-year rate is the figure quoted in the news; the month-over-month change is the one that moves markets on the day.
