Core CPI YoY - November 2026
Leaning No: the latest core CPI trend is too hot for 2.3% or lower. October core CPI rose 0.3% for the third straight month, and the last published annual reading was already 2.6% in September 2026.
Analysis
On November 10, 2026, BLS said October core CPI rose 0.3% month over month, matching the prior two months. That pace points to a November year-over-year reading well above 2.3% unless there is an unusually sharp slowdown in the next print.
The last published annual core rate was 2.6% for September 2026, and the November release on December 10 will be the first clean comparable annual reading after the missing October 2025 data issue. To get to 2.3% or lower, the unadjusted index would need a clear drop in momentum, which the recent monthly data do not support.
Arguments
For
- October core CPI was 0.3% month over month, which is faster than the 0.2% consensus and not consistent with a quick drop to 2.3%.
- September 2026 core CPI was already 2.6% year over year, so the market needs a meaningful deceleration in just one month to hit the threshold.
- Shelter remained firm in October, suggesting core inflation is still being supported by sticky categories.
Against
- The market is only asking for 2.3% or lower, not a much lower figure, so a modest easing in November could still get close.
- The annual comparison is complicated by missing prior-year data, which could make the final reported number slightly less predictable.
Key drivers
- Three consecutive 0.3% core CPI monthly gains signal persistent inflation pressure heading into the November reading.
- The last available annual core CPI reading was 2.6% in September 2026, leaving limited room for a fall to 2.3% or lower.
Risk factors
- If November prices come in much softer than October, the annual rate could surprise down toward the threshold.
- The missing October 2025 comparison data makes the year-over-year calculation less intuitive, so the final one-decimal figure could shift more than expected.
Scenarios
Best case
If the December 10 BLS report shows a sharp November core CPI slowdown and the annual reading lands near 2.2% or 2.3%, Yes rises to about 20%.
Most likely
Most likely the November 2026 core CPI print stays above 2.3%, with Yes around 3% to 5%.
Worst case
If November core CPI repeats another 0.3% monthly gain or stronger on December 10, Yes falls to about 1%.

Next CEO of NVIDIA?
AI2%MKT27%Edge-25HypedSlight lean to No: the market is only 4%, and the key fact is that NVIDIA has not announced Colette Kress as Jensen Huang’s successor as of November 11, 2026. The current reporting treats her as a possible interim or continuity choice, which would not satisfy the rule.
