Core CPI vs Core PCE
Live side-by-side comparison with current values, changes, and key statistics.
Why This Comparison Matters
Core CPI and Core PCE differ in weights (PCE has lower shelter weight) and scope (PCE covers more healthcare). PCE typically runs 30-40bp below CPI over time. Large persistent divergence between them usually reflects shelter or healthcare dynamics and matters for policy because the Fed targets PCE.
Cross-Asset Analysis
Core CPI (ex Food/Energy) measures CPI excluding food and energy, less volatile measure of underlying inflation, while Core PCE (ex Food/Energy) measures core PCE excluding food and energy, the single most important inflation metric for the Fed; tracking the two side by side turns that distinction into a tradable signal for the peer pair relationship. Flows matter for the Core CPI (ex Food/Energy)-Core PCE (ex Food/Energy) relationship: when one peer attracts more capital, it outperforms on demand pressure that often mean-reverts. Mid-cycle stretches see the Core CPI (ex Food/Energy)-Core PCE (ex Food/Energy) spread compress as macro volatility stays low and factor returns normalize.
Late-cycle environments force Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) to express their respective defensive and cyclical tilts more sharply, making the spread a useful regime tell. Overlay strategies trade the Core CPI (ex Food/Energy)-Core PCE (ex Food/Energy) spread through options or swaps when the underlying pair is directly tradable, sizing against realized spread volatility. Pairs like Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) trade tighter than either leg does individually, because the common component is high and the remaining idiosyncratic share is what the pair expresses.
Liquidity differences between Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) produce asymmetric spread moves during risk-off episodes. Performance attribution leans on Core CPI (ex Food/Energy)-Core PCE (ex Food/Energy) spreads to separate security selection from style allocation inside multi-manager mandates.

Frequently Asked Questions
What is the relationship between Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy)?+
Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) are connected through shared asset class exposure with different factor tilts. When the underlying asset class shifts, both respond, though with different sensitivities and at different speeds. The spread between Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) captures the specific macro signal that flows through this relationship.
When does Core CPI (ex Food/Energy) typically lead Core PCE (ex Food/Energy)?+
Core CPI (ex Food/Energy) tends to lead Core PCE (ex Food/Energy) during rotation episodes between the two factor exposures. In those periods, moves in Core CPI (ex Food/Energy) precede corresponding moves in Core PCE (ex Food/Energy) by days to weeks, depending on the transmission channel and the depth of each market.
How are Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) historically correlated?+
Long-run correlation between Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) varies by regime. Peers in the same asset class are highly correlated in direction, with the spread reflecting factor tilts and rotation dynamics. The correlation is not stable: it shifts with macro conditions, and the periods when it breaks down are often the most informative moments in the Core CPI (ex Food/Energy)-Core PCE (ex Food/Energy) relationship.
What macro conditions drive divergence between Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy)?+
Divergence between Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) typically arises from index reconstitution, mega-cap earnings surprises, or liquidity differences between the peers. When one asset's idiosyncratic drivers dominate, the spread moves in ways that the common macro story does not predict, which is usually a signal to look more carefully at the specific drivers at work in Core CPI (ex Food/Energy) or Core PCE (ex Food/Energy).
Is Core CPI (ex Food/Energy) a hedge for Core PCE (ex Food/Energy)?+
Peers like Core CPI (ex Food/Energy) and Core PCE (ex Food/Energy) do not hedge each other; both rise or fall with the shared asset class, and using the pair as a spread trade is different from using it as a hedge. Effective hedging requires matching the hedge to the specific risk being protected, and the Core CPI (ex Food/Energy)-Core PCE (ex Food/Energy) pair is best stress-tested under scenarios the investor most worries about before being sized into a real portfolio.
