Will CPI Core rise more than 0.4% in November? — Above 0.4%

- [2026-10-14] BLS (the resolution source) reported that September core CPI (all items less food and energy) rose 0.3% seasonally adjusted, the same as August. It was up 2.6% year on year, after 2.4% in August. Headline CPI rose 0.6%. https://www.bls.gov/news.release/cpi.htm - [2026-10-14] Consensus for September core was 0.2% m/m, so the print beat it. CNBC and Dow Jones gave consensus as 0.2% m/m and 2.5% y/y. https://www.cnbc.com/2026/10/14/cpi-inflation-report-september-2026.html - [2026-10-14] TheStreet, citing Bloomberg, put unrounded September core at +0.33%, the most since April, after +0.29% in August. Only 11 of 73 economists had forecast 0.3%. https://pro.thestreet.com/market-commentary/hot-cpi-puts-october-rate-hike-back-in-play - [2026-10-14] September drivers: shelter +0.4% (August +0.3%), used cars +0.7%, apparel +0.3%, plus airline fares, medical care, recreation and education. Communication fell. Gasoline rose 9.1% and energy 5.2% (Iran war energy shock, started late February). Core is not above 0.4% in any recent month shown in the sources I read. https://www.cnbc.com/2026/10/14/cpi-inflation-report-september-2026.html - [2026-10-14] The Cleveland Fed nowcast for October 2026 (updated 10/14) shows core CPI at 0.21% m/m and 2.48% y/y. It shows 3.02% annualized core for Q4. I found no November m/m nowcast on the page. https://www.clevelandfed.org/indicators-and-data/inflation-nowcasting - [2026-10-14] Carson Group's Varghese noted that core ran at a 3.7% annualized pace in September. He flagged lagged effects from diesel costs and AI-related demand. https://www.cnbc.com/2026/10/14/cpi-inflation-report-september-2026.html - [2026-10-12] Pre-release views: Bank of America expected second-round energy effects to stay "relatively contained". Core forecasts were mostly 0.2% (Goldman and Morgan Stanley 0.24%, Deutsche Bank 0.16%). Actual came in at 0.3%. https://www.morningstar.com/economy/cpi-forecasts-show-moderated-inflation-september-keeping-fed-hold - [2026-10-14] Fed context: the Fed hiked 25bp in September, to a 3.75%–4% target range. After the CPI, markets priced about a 54% chance of an October 27–28 hike and over 96% for a hike by December. https://www.cnbc.com/2026/10/14/cpi-inflation-report-september-2026.html - [2026-02-18] The BLS schedule shows the October CPI on 2026-11-10 and the November CPI on Thursday 2026-12-10 at 8:30 ET. The market closes 2026-12-10, the same day as the release. https://www.bls.gov/schedule/news_release/current_year.asp - [2026-Q3] The Philadelphia Fed Q3 SPF (published about August) expected core CPI at 2.7% annualized for the current quarter and 2.8% Q4/Q4 for 2026. Both are well below a 0.5% monthly pace. https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q3-2026 - [2026-10-14] BLS says CPI October 2025 data were never collected because of the 2025 shutdown. October 2026 12-month changes will be missing for many series. This does not affect the November 2026 m/m seasonally adjusted figure directly. https://www.bls.gov/cpi/additional-resources/2025-federal-government-shutdown-impact-cpi-faq.htm - [2026-10-15] I found no sign of a current 2026 federal shutdown affecting BLS. The search results only covered the 2025 shutdown. https://www.bls.gov/cpi/ BOTTOM LINE: Core CPI has been running at 0.3% m/m (unrounded about 0.29% in August and 0.33% in September), and the Cleveland Fed nowcast for October is about 0.2%. A November print of 0.5% or higher (above 0.4%) would need a clear acceleration, though upside risks exist from energy pass-through and shelter. NOT FOUND: A November-specific core m/m consensus or nowcast (not yet published). The full 2026 monthly core series, including whether any month this year printed above 0.4%. Any 2026 shutdown risk before December 10.

**Threshold:** "Above 0.4%" on the single-decimal SA core print means a reading of 0.5% or higher. - [2026-10-14] September core CPI was +0.3% m/m (unrounded about 0.335%), 2.6% y/y. Consensus was 0.2%. August was also +0.3%. Core services rose 0.4%, shelter 0.4%, and the 3-month annualized core rate was 3.4%. https://economics.td.com/us-cpi - [2026-10-14] The 2026 core m/m prints, as reported across sources, are: Jan 0.2 (headline-table figure, check), Feb 0.3, Mar 0.2, Apr 0.4, May 0.2, Jun 0.0, Jul 0.2, Aug 0.3, Sep 0.3. The maximum in 2026 is 0.4, and none reached 0.5. https://fedratecalc.com/cpi-release-date/ ; https://www.forexfactory.com/calendar/79-us-core-cpi-mm - [2026-05-12] The April 0.4% core print included a one-off catch-up in rent and owners' equivalent rent (OER) for data BLS could not collect during the 2025 shutdown. Core fell back to 0.2% in May. https://verifiedinvesting.com/blogs/us-economic-metrics/us-cpi-may-2026-headline-energy-core-cooling - [2026-10-14] Cleveland Fed nowcast for October 2026 core CPI is +0.21% m/m, with core 2.48% y/y and Q4 core CPI at a 3.02% annualized rate. The September core nowcast was 0.20%, against an actual of about 0.335%, so it undershot by roughly 0.13pp. There is no November-month nowcast yet. https://www.clevelandfed.org/indicators-and-data/inflation-nowcasting ; https://en.macromicro.me/collections/5/us-price-relative/27688/us-cleveland-inflation-cpi - [2026-10-14] Macro backdrop: energy is up sharply because of the US–Iran war that began in late February. Gasoline rose 9.1% in September and is up 34.2% y/y. Airfares are up 22.4% y/y, so pass-through into core is a risk. The Fed (Chair Warsh) hiked in September, and markets are weighing another hike. https://www.cnbc.com/2026/10/14/cpi-inflation-report-september-2026.html ; https://www.kiplinger.com/investing/economy/cpi-report-september-2026-what-to-expect ; https://tradingeconomics.com/united-states/core-inflation-rate - [2026-10-15] September PPI was hot at +1.3% m/m, the largest since March 2022. PPI excluding food, energy and trade services rose 0.5%. Core PCE for September is estimated at about 0.32%. https://cnbc.com/2026/10/15/pce-ppi-september-fed-reserve-rate-hike.html - [2026-05] The Philadelphia Fed Q2 SPF expected core CPI at a 3.2% annualized rate for Q2 and 2.9% Q4/Q4 for 2026. That implies roughly 0.25% per month, which is well below 0.5%. https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q2-2026 - [2026-10-12] Kalshi traders see core CPI staying elevated this year. They put only a 6% chance on core y/y falling below 2.2%. This is a y/y market, not a November m/m strike. https://www.cnbc.com/2026/10/12/inflation-will-remain-sticky-in-2026-according-to-prediction-markets.html - [2026-10-14] The November 2026 CPI is scheduled for release on Thursday 2026-12-10 at 08:30 ET. That is the same day the market closes. The October CPI is due 2026-11-10. https://www.bls.gov/cpi/ ; https://www.bls.gov/schedule/news_release/current_year.asp - [2026-08-12] Historical base rate, from my own recollection and not verified in this session: core CPI m/m at or above 0.5% was common only in 2021–Sept 2022 (e.g., 0.6% in Sept 2022). Since early 2023 I recall no print at or above 0.5%, so the 2023–26 YES base rate is near 0%. The 2026 monthly range of 0.0–0.4% is consistent with this. https://www.wichitaliberty.org/economics/july-2026-cpi-report-inflation-3-4-percent/ - [2026-10-14] Recent consensus misses on core have been modest, about ±0.1pp. Examples: Sept actual 0.3 vs 0.2 expected; Jun 0.0 vs 0.2; Apr 0.4 vs 0.3 expected (a one-off). A 0.5% print would need a miss of about 0.25pp or more versus a ~0.2–0.3% consensus. https://www.forexfactory.com/calendar/79-us-core-cpi-mm BOTTOM LINE: Outside view strongly favors NO. Core has not printed 0.5% or higher in the 2026 data I found (max 0.4, and that one was boosted by a one-off), and I recall none since early 2023. Upside tail risk is somewhat elevated by energy pass-through, hot PPI and a core trend drifting up to about 0.3%, and the release lands on the closing date (Dec 10). NOT FOUND: Any consensus or nowcast for November 2026 core CPI (too early). Any Kalshi or other market strike for November core m/m (deliberately not searched). A verified historical series of core m/m prints for 2023–25. The Cleveland Fed page's full nowcast table, which loaded only partly, so its October figure comes from the search snippet.

YES means: the BLS seasonally adjusted core CPI (all items less food and energy) for November 2026, released 2026-12-10 and rounded to one decimal, is 0.5% or higher. - [2026-10-14] **Breadth of the September core beat.** Core services outside housing ran 0.35% in July, 0.41% in August and 0.34% in September. That is a three-month average of 0.37%, or about 4.5% annualized. Shelter went 0.1%, 0.3%, 0.4% over July to September, and lodging away from home rose 2.0%. The September data also show OER at 0.3% and rent at 0.2%. https://piedmontcrescentcapital.com/september-cpi-2026-gasoline-moves-the-headline-services-move-the-trend/ - [2026-10-14] **Accelerating three-month trend.** Core has compounded at a 3.4% annual rate over three months, up from 2.0% in August. Piedmont's HP-filter trend rose for a second straight month, to 2.61%. Piedmont expects the Fed to hike on Dec 9, a day before the November CPI. https://piedmontcrescentcapital.com/september-cpi-2026-gasoline-moves-the-headline-services-move-the-trend/ - [2026-10-14] **Forecasters have been missing low.** The Bloomberg survey had only 11 of 73 economists at 0.3% or higher. Unrounded core was 0.335% against a 0.21% consensus, a 0.125pp miss. Capital Economics' September core PCE estimate is 0.32%, which would lift its three-month annualized rate to 2.8% from 2.0% in August. Bloomberg's live blog also says some outsized gains pointed to tariff and AI effects. https://www.bloomberg.com/news/live-blog/2026-10-14/us-cpi-for-september-live-updates - [2026-10-14] **Energy pass-through channel.** Fuel oil rose 15.3% in September and is up 74.2% y/y. Gasoline is up 34.2% y/y. The US-Iran war continues, and Bloomberg cites $100-plus crude. Transportation services have accelerated four straight months, to +0.6% in September. Airfares are up 22.4% y/y even though the monthly gain slowed to 1.2% from 2.7%. Fare, delivery and travel costs can lag fuel costs. https://piedmontcrescentcapital.com/september-cpi-2026-gasoline-moves-the-headline-services-move-the-trend/ - [2026-10-14] **Broadening beyond energy.** Principal Asset Management says more than half the CPI basket is running above a 3% annualized pace. An analyst quoted by US News says pressures are "broadening beyond energy". https://money.usnews.com/investing/news/articles/2026-10-14/hot-september-cpi-sends-rate-hike-bets-soaring - [2026-10-13] **Cost-side pipeline.** Analysis written before the September PPI release said final-demand PPI was up 0.4% and PPI excluding food and energy up 0.2%. Energy accounted for more than three-quarters of the goods increase. Continuum Economics expected "energy pass-through to bring continued strength in air fares". The hot September PPI of +1.3% noted in the colleague report is the newer input. https://www.fxstreet.com/analysis/cpi-preview-september-2026-energy-drives-headline-but-core-is-where-the-real-action-is-202610141005 - [2026-10-15] **Kalshi's own strike-by-strike history (not this contract).** Volume for the September core m/m market was concentrated at 0.1–0.3% but showed some trading at 0.4%, 0.5% and 0.6%, so a fat right tail is priced as possible. Source: https://ticker-tracker.com/m/kxcpicore. Kalshi y/y markets for November core (as of mid-October) show about 51% for above 2.8% and about 22% for above 2.9%, versus 2.6% now. Reaching 2.9% would need core to run hotter than September's pace. Source: https://kalshi.com/category/economics. A third-party snapshot dated about Aug 17 listed a November ">0.5%" strike, but it is stale and I did not use it. - [2026-10-14] **Single most likely path to YES.** The path is a stacked-upside month, which is the only way unrounded core reaches about 0.45% or more. - Shelter would stay at or above 0.4%, driven by lodging and rising OER. - Services outside housing would stay at 0.4% or higher. - Airfares, transport and delivery would take up lagged fuel costs. - Core goods would add a firm contribution: used cars were +0.7% in September, and apparel was +0.3%. - A holiday-season or seasonal-adjustment quirk could add to this. - The September shelter and services data show the first two items already happening. Sources: https://www.bls.gov/news.release/cpi.nr0.htm and the Piedmont page above. - [2026-12-10] **Data-quality noise.** The November release is on 2026-12-10, the same day the market closes. BLS collected no October 2025 data, and the 2025 November/December figures were imputed. This leaves a wider noise band around the CPI series and a possible seasonal-factor distortion. I could not confirm that this raises or lowers the odds of a 0.5% print. https://www.bls.gov/cpi/additional-resources/2025-federal-government-shutdown-impact-cpi-faq.htm BOTTOM LINE: The best YES argument is that core has accelerated to a 3.4% three-month pace, that forecasters keep under-forecasting it, and that fuel pass-through into airfares, transport and services is still ongoing. Even so, YES needs a further jump of about 0.15–0.2pp above September's 0.335%. This is a tail outcome that needs several components to run hot at once. NOT FOUND: A November core m/m consensus or nowcast. A November core m/m Kalshi price (deliberately not sought). Any evidence of a 2026 shutdown threat before Dec 10. Any analyst forecast of a 0.5% core print.

YES means: the BLS seasonally adjusted core CPI (all items less food and energy) for November 2026, published as a single decimal, is 0.5% or higher month over month. A 0.4% print resolves NO. - [2026-10-15] The Dec 10 release does not look exposed to a shutdown. A Holland & Knight alert (Oct 9) says the current continuing resolution funds the government through Dec 11, 2026, one day after the scheduled CPI release. It says a partial shutdown "remains possible" only if there is no deal before Dec 11. A delay cannot hit before the Dec 10 release, so the extension clause is unlikely to matter. If it did, the Dec 10 close would just give a later resolution date, not a Yes. https://www.hklaw.com/en/insights/publications/2026/10/beyond-the-midterms-congress-faces-converging-year-end-deadlines - [2026-10-15] BLS lists the November 2026 CPI for Dec 10 at 08:30 ET. It also lists the October CPI for Nov 10. Several independent calendars repeat the same dates. https://www.bls.gov/schedule/news_release/cpi.htm - [2026-10-15] YCharts' monthly core series shows 0.4% as the highest print from Jan 2023 to Jun 2026. That covers Jan 2025 (0.4), Mar 2024 (0.4), Feb 2024 (0.4) and Apr 2026 (0.4). Core was 0.0% in Jun 2026. Seasonally adjusted core has not been at or above 0.5% since Sep 2022 (0.58) in that series. Jan 2023 was 0.42 and Feb 2023 was 0.47, both unrounded, and both would print as 0.4 (Feb 2023 rounds to 0.5 at one decimal, so check it). That is roughly 3.5 years of prints, at most one borderline. https://ycharts.com/indicators/us_core_consumer_price_index_mom - [2026-10-15] The shutdown-affected months add no upside tail. Wells Fargo's Dec 2025 preview expected only a 0.48% core gain across two months, Sep to Nov 2025. The Nov 2025 m/m was never published. So there is no one-month spike precedent in the recent data. https://www.fxstreet.com/analysis/november-cpi-preview-detour-around-the-october-pothole-202512161537 - [2026-10-15] The Cleveland Fed's October core nowcast is 0.21% m/m (updated 10/14), which implies a Q4 core annualized rate of 3.02%. A 3.02% annualized Q4 rate averages about 0.25% a month, so the model does not put a 0.5% month in the quarter. https://www.clevelandfed.org/indicators-and-data/inflation-nowcasting - [2026-10-12] Natixis (Hodge), quoted in Morningstar's June preview, said the Iran-war energy shock "was not broadly passed through" to core goods. JPMorgan's Kasman said core looks sticky at about 3% annualized. That is about 0.25% a month, not 0.5%. https://www.morningstar.com/economy/why-economists-expect-biggest-cpi-slowdown-years-while-core-inflation-remains-sticky - [2026-10-12] Bank of America called second-round effects "relatively contained" before the September print. It saw risks as only "modestly skewed" up. Its upside scenario was another 0.3%, not 0.5%. Even after the hot September, the consensus miss was about 0.1pp. https://www.morningstar.com/economy/cpi-forecasts-show-moderated-inflation-september-keeping-fed-hold - [2026-10-14] The detail behind September's 0.33% shows how much more it would take to reach 0.5%. Supercore was 0.42% in September after 0.51% in August. Even so, headline core landed at about 0.3%, because goods and communication offset the services strength. The Bloomberg Economics forecast was 0.23%. A 0.5% print needs roughly another 0.17pp on top of September's hot reading. https://pro.thestreet.com/market-commentary/hot-cpi-puts-october-rate-hike-back-in-play - [2026-10-15] Mean reversion applies to the one-off boosts. The April 0.4% was a shutdown-related rent catch-up (reported by colleagues). September shelter and used cars (+0.7%) are volatile components, and used-car swings tend to reverse. Nothing flagged for November is a comparable scheduled one-off. I found no source forecasting a November catch-up or methodology change. https://ycharts.com/indicators/us_core_consumer_price_index_mom - [2026-10-15] Year-on-year core is 2.6% and the 2026 index path is steady. YCharts shows core y/y between 2.5% and 2.9% all year. A one-month 0.5% would add about 0.2pp to the y/y rate. Forecasters, Kalshi traders and the SPF all expect core to stay near its current range. https://ycharts.com/indicators/us_core_consumer_price_index_yoy - [2026-10-15] The SPF forecast was 2.9% Q4/Q4 core for 2026 in the Q2 survey (May) and 2.8% in the Q3 survey. Both are revised only modestly even after the Iran-war shock. https://www.philadelphiafed.org/surveys-and-data/real-time-data-research/spf-q2-2026 BOTTOM LINE: A NO needs only that core stays at 0.4% or lower. Core has not printed 0.5% in about 3.5 years, nowcasts and surveys point to about 0.2–0.3% a month, and no shutdown can block the Dec 10 release. The main residual risk is a clustering of energy pass-through (airfares, shelter, used cars) at the tail. NOT FOUND: Any November core m/m consensus, nowcast or Kalshi/other-market strike (too early). Evidence of a shutdown or BLS disruption before Dec 10. A fetched copy of the BLS CPI release (the BLS page was not opened this session). The YCharts page loaded only via search snippet, so the 2023–26 series is unverified on the full page.
