Core PCE
The Fed's preferred inflation gauge: the PCE price index excluding food and energy — the gauge the Fed watches to track its 2% inflation goal.
Formula
Core PCE YoY = (Core PCE Index now / Core PCE Index 12 months ago - 1) x 100
Core PCE is the Personal Consumption Expenditures price index stripped of its volatile food and energy components. Published monthly by the Bureau of Economic Analysis, it is the Fed's preferred inflation gauge — the Fed's formal 2% longer-run goal is defined on headline PCE (not CPI), and core PCE is its preferred guide to where that headline trend is heading.
PCE differs from CPI in two important ways: it covers a broader basket and reweights spending as consumers substitute toward cheaper goods, so it typically runs a few tenths below core CPI. The Fed favors it precisely because that substitution and broader scope make it a more complete read on underlying price pressure. Stripping out food and energy removes the noisiest categories, revealing the persistent trend that actually drives policy.
For traders this is the single most important inflation print for anticipating rate decisions. A core PCE reading that surprises hot or cold reprices the entire rates curve and every risk asset alongside it — and because it lands weeks after CPI, markets often try to back into it from the earlier CPI and PPI data.
Example
If headline PCE rises 2.6% year-over-year but core PCE sits at 2.8%, the Fed reads the higher core figure as the truer signal of embedded inflation and is likely to hold rates higher for longer — even though falling energy prices made the headline look tamer.
