Services CPI Ex-Housing (Super-Core)

What Is Super-Core?

Services CPI excluding shelter, often called "super-core" inflation, isolates the slice of consumer prices most sensitive to wages and labour-market conditions. It became the Fed's reference measure during the 2022-2024 cycle after Chair Powell argued in a November 2022 speech that this category would determine whether the Fed succeeded against the inflation surge.

Super-core is not an official BLS or BEA series; it is constructed by analysts from the published sub-components. The most common definition removes the entire shelter line from services CPI, leaving roughly 25% of the headline basket: medical services, transportation services, recreation, financial services, education, communication, and personal care.

Why It Matters for Markets

Super-core matters because it reflects the labour-market-to-inflation transmission most directly. Wages drive services pricing in a way they do not drive goods pricing (where global supply chains anchor costs) or shelter pricing (where lease structures and housing supply dynamics dominate). If wage growth runs above the level consistent with 2% inflation, super-core stays sticky and the Fed cannot declare victory.

On every CPI release day, traders and Fed-watchers compute the super-core change immediately. A 0.4% monthly super-core print versus 0.2% can swing 2-year yields by 10-20 basis points because it signals the labour-market channel has not yet broken.

How to Read the Print

Three sub-categories drive super-core dynamics:

Medical services — about 30% of super-core. The CMS administered prices and insurance-driven dynamics make this category lag wage growth more than other services. Watch for inflection 12-18 months after wage acceleration.

Transportation services — airfares, motor vehicle insurance, vehicle maintenance. Highly volatile month to month; smooth on 6-month windows. Vehicle insurance ran above 20% YoY through 2024 as policies repriced against accumulated claims inflation; the deceleration of this single category drove much of the 2024-2025 super-core slowdown.

Recreation, personal care, financial services — the most wage-sensitive sub-categories. These tend to be the late-cycle stickies. A persistent acceleration here when other categories are decelerating is the canonical "wage-price spiral risk" signal.

Historical Context

Super-core averaged approximately 2.5-3.0% during the 1990s and 2010s expansions, well-anchored. The 2022 peak reached approximately 6.5%, the highest since the early 1980s. Through 2023-2024 it decelerated to roughly 4.5%, and by 2025 had moved into the 4.0-4.3% range — still above the comfort zone but trending toward consistency with the 2% headline PCE target.

The 3-month annualised rate is the cleanest leading signal. A sustained run below 3% on that basis would be the strongest evidence that the labour-market transmission has broken in a way that makes 2% headline achievable.
