Core CPI vs Core PCE
Core CPI (BLS, FRED series CPILFESL) and Core PCE (BEA, FRED series PCEPILFE) differ chiefly because CPI weights shelter at roughly 33% versus 15% for PCE, and PCE captures employer-paid healthcare while CPI only counts out-of-pocket spending. Core CPI has historically run about 47bp above Core PCE since 1960 and printed higher in roughly 80% of monthly observations, but in November 2025 Core PCE overtook Core CPI for the first time since 2021 as services-driven shelter disinflation pulled CPI lower.

Why This Comparison Matters
Core CPI (BLS, FRED series CPILFESL) and Core PCE (BEA, FRED series PCEPILFE) differ chiefly because CPI weights shelter at roughly 33% versus 15% for PCE, and PCE captures employer-paid healthcare while CPI only counts out-of-pocket spending. Core CPI has historically run about 47bp above Core PCE since 1960 and printed higher in roughly 80% of monthly observations, but in November 2025 Core PCE overtook Core CPI for the first time since 2021 as services-driven shelter disinflation pulled CPI lower. The Fed targets 2% on Core PCE because it covers a wider expenditure basket and adjusts more quickly to substitution.
What Core CPI and Core PCE actually measure
Core CPI (CPILFESL on FRED) is published by the Bureau of Labor Statistics from the Consumer Price Index for Urban Consumers, dropping food and energy and using a Laspeyres-style fixed-basket framework that updates weights every two years. Core PCE (PCEPILFE) is constructed by the BEA from Personal Consumption Expenditures and uses a Fisher-ideal chain index that updates weights monthly. The two indices are built off different source surveys: CPI relies on the Consumer Expenditure Survey of household spending, while PCE relies on retail-sales receipts and business surveys, which is why PCE captures Medicare and employer-paid health insurance that never appears on a household receipt.
The Fed has formally targeted Core PCE since 2000 and explicitly committed to 2% in January 2012 at the FOMC. Core CPI is what households recognize because BLS releases it on the second Tuesday of the month, weeks before BEA releases the corresponding PCE. As of the BLS release covering March 2026, Core CPI ran 2.6% year-over-year while Core PCE printed 3.2% in the same window, the rare configuration where Core PCE exceeded Core CPI.

Frequently Asked Questions
Why does the Fed target Core PCE instead of Core CPI?+
The Fed switched its preferred measure to PCE in 2000 and formally to Core PCE around the 2012 FOMC. PCE uses a Fisher-ideal chain index that updates weights monthly, captures third-party-paid healthcare like Medicare and employer insurance, and covers the broader basket of consumer spending recorded in the national accounts. The Fed's reasoning is that PCE better reflects what consumers actually face after substitution, while CPI's fixed-basket Laspeyres methodology overstates inflation when consumers switch to cheaper alternatives.
How much does Core CPI typically run above Core PCE?+
The long-run average gap since 1960 is roughly 47 basis points, with Core CPI higher in about 80% of monthly observations. The gap is structural, not random, and is driven primarily by the shelter weight (33% in CPI versus 15% in PCE). When OER prints high, the gap widens; when shelter cools and services inflation persists in healthcare, the gap can compress or invert, as it did in November 2025.
Which series leads the other at turning points?+
Neither one consistently leads the other. Core CPI prints first each month and is the public anchor that markets react to, but Dallas Fed Trimmed-Mean PCE has the best track record of leading Core PCE turning points by one to two months because it strips outliers. The cleanest workflow is to use Trimmed-Mean PCE for the inflection signal, Core CPI for the high-frequency check, and Core PCE for the policy read.
Why did Core PCE go above Core CPI in late 2025?
