    Missing CPI data makes victory lap premature

    Instant Insights:Missing cpi data makes victory lap premature

    December 18, 2025 Fixed income

    Headline and core consumer prices rose 0.2% over October and November. This took headline CPI from 3% to 2.7% (the slowest since June and core CPI from 3% to 2.6% (the slowest since March 2021).

    Due to the recent government shutdown, the Bureau of Labor Statistics was unable to collect most data for October leaving most month-on-month data points missing for October and November.

    Energy prices rebound, but other major sectors ease

    Energy prices rose 1.1% over the 2-month period to November, with notable gains year-over-year in fuel oil and electricity. Elsewhere, food inflation was modest, at 0.1% over the two months.

    Meanwhile, the “sticky” core services sectors continued to show improvement.

    Shelter (the largest component of the CPI) reached 3% year-over-year in November, the lowest since August 2021 (Figure 2). However, given disruptions to the housing surveys in October, we are cautious about over-interpreting the figure. Excluding shelter, CPI was 2.6%.

    “Supercore” services (which exclude the rental component of shelter), eased from 3.2% year-over-year in September to 2.7% in October, with transportation services and medical care services both easing year-over-year (Figure 2).

    Tariff inflation proves mild, but may still be factor over the coming months

    Core goods inflation was 1.4% year-over-year, the slowest since July 2025. Most categories, including those that are tariff-sensitive, were largely contained on a year-over-year basis in November. We expect the tariff inflation will nonetheless peak over the coming months, reflecting the rising effective US tariff rate (Figure 3).

    Conclusion: Data quality concerns make it too early to take a victory lap

    While the Fed will likely be encouraged by the latest print, disruptions to the October CPI survey data mean it is too early to take a victory lap. It will likely take a least a couple of months before we can become more confident that disinflationary trends remain in place.

    However, we expect core services will ultimately continue to show disinflation. Although the Fed will keep an eye on tariff inflation, we expect this will keep the central bank open to rate cuts in 2026 if the labor market shows signs of tipping into a contraction.
