U.S. Macroeconomic Analysis and October 2026 Consumer Price Index Forecast: A Comprehensive Research Report

Editor's Note

This is a living CPI research article updated throughout the month as new inflation-relevant developments emerge. It includes macro and market monitoring and, later in the cycle, incorporates XTech's internal CPI forecast ahead of the official BLS release (typically ~10 days and ~2 days before).

This version was last updated on November 3, 2026. It covers October 1–31, 2026 in one full-month review and includes XTech's Second and Final Forecast for October CPI (BLS release: November 10).

What changed in this version: first October edition, with full-month surveillance analysis evidence across eight categories and the final forecast.

XTech CPI Forecast Methodology

XTech's CPI forecasts are produced by a machine learning model trained on historical data, consumer survey data, and bespoke alternative datasets. The model uses a one-step-ahead ("teacher forcing") technique: at each forecast cycle it learns from the most recent actual release rather than from its own prior predictions, keeping it continuously calibrated to current conditions.

What we forecast

Two CPI forecasts are published each month:

• First Forecast — released approximately 20 calendar days before the official BLS CPI release, before sell-side consensus is established. Headline MoM metrics: correlation 87%, directional accuracy 81%, MAE 0.001 (Nov 2017 – Sep 2025).

• Second Forecast — released approximately 5 calendar days before the official release, incorporating additional data inputs available later in the cycle. Headline MoM metrics: correlation 88%, sign accuracy 95%, MAE 0.0009.

Both forecasts cover headline CPI and core CPI (MoM and YoY). Category-level forecasts are also available for: Gasoline, Transportation Services, Used Cars & Trucks, Food, Shelter, Medical, Education, Recreation, Electricity, Apparel, and Utility.

Why XTech CPI forecasts outperform consensus

Last month’s scorecard

September ran hotter than XTech forecast on all four measures. Our Second and Final Forecast called headline CPI at +0.5% and core at +0.2%; BLS reported +0.6% and +0.3%. Gasoline was not the source of the miss: it rose 9.1% seasonally adjusted, against our +10%. Core was. Used cars (+0.7%) and motor vehicle insurance rose against our base case, and lodging (+2.0%) and airfares (+1.2%), the upside risks we named, both came through.

XTech CPI Forecast — September 2026

XTech published its Second and Final Forecast for October CPI on November 3, seven days before the BLS release. The card below sets it against September's actual figures and the consensus at publication, with unrounded values.

Key drivers (from the month's surveillance evidence):

• Gasoline flattens after September's 9.1% jump (≈ −0.9% before seasonal adjustment in October)

• Shelter steady near 0.3% a month

• Wage growth cooling (ECI wages +0.7% q/q)

Upside risks:

• Used cars and airfares; core sits 1.4 bp below the +0.3% rounding line

Downside risks:

• Hotel prices giving back part of September's 2.0% jump

• Gasoline seasonal adjustment

*BLS will not publish October 2026 12-month changes for most series because October 2025 data were never collected; if the annual rates are not published, those rows cannot be scored

October 2026 CPI Surveillance

Eight categories, each scored for direction and magnitude from the evidence published between October 1 and November 2.

1. Energy and Global Commodities

Energy stops driving the headline. U.S. regular gasoline slipped from $4.35 a gallon in the first week of October to $4.27 by October 26, according to the EIA's weekly retail survey. The four-week average of about $4.31 is roughly 0.9% below September's $4.35 before seasonal adjustment. October seasonal factors typically expect pump prices to fall, so the seasonally adjusted gasoline change could land close to flat. Either way, September's surge does not repeat, consistent with XTech's headline forecast slowing to +0.2%.

Crude moved the other way. Brent futures reached six-month highs in late October on attacks on Saudi facilities and fears of escalation with Iran, and EIA data put spot Brent at $128 a barrel on October 23. Retail gasoline typically follows crude with a lag of a few weeks, so that rally is a November risk. Diesel is already in the October data: it rose from $6.18 to $6.35 over the second half of the month, feeding fuel oil directly and freight costs indirectly. Natural gas stays soft, with storage above its five-year average.

2. Trade Policy and Tariffs

Import prices are still rising, but October's tariff actions were too small and too late to move this print. Nonfuel import prices rose 0.7% in September and 6.0% over the year, up from 5.5% in August, according to BLS, with prices of goods from Canada up 1.3% in the month. The main policy change was a narrow revision to the Section 338 tariffs on Canadian goods, removing plywood, some paper products and certain machinery and adding items such as valves and carpets. It took effect on October 30, too late to register in October prices.

New York Fed research published on October 6 helps with timing. It finds nearly 90% of a tariff passing into import prices within about a month, half of the direct retail effect appearing after three months, and the full effect taking about a year. On that timetable, the 2025 tariff increases are dropping out of year-over-year goods inflation, while the next identifiable goods risk is the January 2027 increase on Canadian cars, trucks and auto parts. For October, trade is a mild upward force concentrated in core goods.

3. Labor Market and Wages

Labor costs are cooling, the main disinflationary force in the October picture. The Employment Cost Index showed wages and salaries up 0.7% in the third quarter, down from 0.9% in the second, with total compensation up 0.8% and 3.4% over the year. Wage growth of 3.1% a year now trails headline inflation of 3.7%.

Hiring confirms the picture. Payrolls rose just 29,000 in September, and July and August were revised down a combined 60,000. Unemployment held at 4.2%, and average hourly earnings rose 0.1% on the month and 3.0% over the year. BEA data show real disposable income fell 0.3% in September as prices outpaced income.

The mechanism is slow. Cooler wage growth eases cost pressure on labor-intensive services such as restaurants, medical care and personal services, but that relief reaches CPI over quarters rather than weeks. It supports the medium-term disinflation case more than it moves the October print. The October jobs report on November 6 will show whether hiring has stabilized.

4. Manufacturing, Logistics, and Supply Chain

The cost pipeline has reached producers, though October brought the first signs of easing. Producer prices for final demand jumped 1.3% in September, the largest rise since March 2022, and 6.3% over the year, according to BLS. Energy accounted for most of the goods increase, but services also rose 0.8%, with transportation and warehousing up 3.4% and trade margins up 1.4%, a sign that retailers are passing higher costs on. Core producer prices, excluding food, energy and trade, rose 0.5%.

The ISM manufacturing survey for October showed the prices index easing to 75.2 from 77.9, and the share of firms reporting higher prices falling to 53% from 59%. That is still an elevated reading. ISM attributed it to steel and aluminum, tariffs, and petroleum-based products affected by the Middle East conflict, while supplier deliveries remained slow at 59.1. Respondents cited fuel costs, material shortages and long lead times.

Producer costs usually reach consumer goods prices over one to three months. That timing puts most of September's pipeline pressure into the November and December CPI reports: contained for October core, an upside risk beyond it.

5. Shelter and Housing

Shelter disinflation has stalled near 0.3% a month. Owners' equivalent rent rose 0.3% in September after 0.2% in August, while rent of primary residence held at 0.2%. Overall shelter rose 0.4%, lifted by a 2.0% jump in hotel prices. Zillow's October CPI shelter forecast calls for OER of +0.27% and rent of +0.23% in October, and says new-lease rents are growing at their fastest pace of 2025–26.

The mechanism explains the plateau. CPI rents track what all tenants pay, not just new leases, and each unit is priced every six months, so they move slowly toward market rents. Zillow expects new-lease and CPI rent growth to converge by year-end, which it says sets a floor under shelter inflation.

Shelter is about a third of the CPI basket, so at 0.3% a month it adds roughly 0.1 percentage point to the headline on its own. That steady contribution is the base under XTech's +0.2% core forecast. Hotels are the swing factor: after September's 2.0% rise, a partial reversal would pull core down, while another gain would push it toward +0.3%.

6. Food and Agriculture

Food prices were flat in September, and the October evidence points to more of the same. The food index was unchanged after seasonal adjustment, with groceries down 0.1% and restaurant prices up 0.2%. Before seasonal adjustment, beef fell 1.3% on the month and dairy 0.9%, and producer prices for eggs dropped 39.7%.

The USDA's October Food Price Outlook projects food prices up 2.8% in 2026, with groceries up 2.3% and restaurant meals up 3.5%. Within that, beef is forecast up 8.7% for the year and eggs down 29.3%, so the protein mix pulls in both directions.

Transport is the cost to watch. Diesel averaged about $6.25 a gallon in October and finished the month at $6.35, more than $2.60 above a year earlier. A food producer in ISM's October survey said diesel and trucker costs had reached "levels I have never seen." Freight costs reach grocery shelves with a lag, so for October the balance looks roughly neutral, with the risk tilting higher into November and December.

7. Services Inflation and Fed Signaling

The Fed is holding with a bias to tighten further, and households are raising their inflation expectations. After raising rates by a quarter point in September to 3.75–4.00%, the FOMC held on October 28 in a 10–2 vote, with Governor Lisa Cook and Cleveland Fed President Beth Hammack preferring another increase. The statement described inflation as elevated, and Chair Warsh noted that energy prices had moved higher again in recent weeks. The September minutes showed most officials expecting another increase to be appropriate by year-end, and Governor Waller said on October 8 that he anticipates additional hikes.

The Fed's stated concern is spread: many participants said the longer energy prices stay high, the greater the risk they feed broader price pressures. September gave some evidence of that, with core up 0.3% and transportation services up 0.6%.

Expectations point the same way. The University of Michigan's final October survey put year-ahead expectations at 4.7% and the 5–10-year measure at 3.5%, both up a tenth. The New York Fed's September survey showed one-year expectations at 3.9%, the highest since May 2023. Policy works with long lags, so none of this changes October's print; it shapes the services outlook for 2027.

8. High-Volatility CPI Components

Used cars and airfares are the two upside risks to XTech's core forecast. Wholesale used-vehicle prices rose 0.7% after seasonal adjustment in the first half of October, according to the Manheim index, and were 2.2% higher than a year earlier. That follows a 0.7% rise in CPI used cars in September, against our expectation of softer prices. Used-car CPI tends to follow wholesale prices with a lag of about two months, so the pressure leans into year-end. Used cars are also the least predictable core category in XTech's model, with a historical correlation of 73%.

Airfares rose 1.2% in September and are up 22.4% over the year. Jet fuel is a distillate, the tightest part of the fuel market, and producer prices for airline passenger services rose in September.

Two items lean the other way. Hotel prices jumped 2.0% in September and would typically give some of that back. Motor vehicle insurance rose only 0.1%, continuing its slowdown, though the series carries extra seasonal-adjustment noise because BLS interpolated its October and November 2025 values.

October's balance is cooler than September's but not benign. Energy, which carried September's headline, turns from the main upward force into a modest one, which is why XTech's headline forecast slows to +0.2% from +0.6%. Core pressure is steady rather than easing: shelter sits near 0.3%, used cars and airfares lean higher, and only labor costs pull clearly the other way. BLS has said it will not publish October 12-month changes for most series because October 2025 data were never collected, so the month-over-month figures are the comparable measures this month.
