Headline vs core, and CPI vs PCE

Headline CPI includes food and energy; core strips them out because they are volatile. The Fed pays closer attention to core and to the month-over-month pace than to the year-over-year headline.

Crucially, the Fed's official 2% target is set on core PCE, not CPI. PCE weights spending differently and usually runs a few tenths below CPI, so the two can tell slightly different stories about the same month.

Prediction markets on inflation usually resolve on the headline CPI year-over-year figure. Confirm the exact resolution source on the market page.
