Core CPI
Consumer Price Index for All Urban Consumers: All Items Less Food and Energy in U.S. City
The number, plainly.
The consumer price index with food and energy stripped out, the measure of inflation that is not about this month's gas price.
Higher, lower, and what each means.
Core running hot means inflation is embedded in rents, services and wages; core cooling is what the Fed waits for before it cuts.
A reading is not a verdict. The Scan phase of Woodring’s Loop collects the signal; the Story phase asks what futures it is consistent with, and only the Stake phase turns that into a decision. This page does the first part.
The line in your 2027 plan.
Tests: whether the rate-cut timing the plan leans on is actually earned by the inflation data.
Write the assumption down, name the reading that would break it, and put a date on when it has to be argued again. That is the 18-Month Sunset applied to one line of a budget. The Last Annual Planshows what this season’s moves have already done to the common ones.
