The Consumer Price Index for All Urban Consumers rose 0.4% on a seasonally adjusted basis in October after rising 0.6% in September, the US Bureau of Labor Statistics reported on 10 November. The index for electricity rose 0.9% over the month, 2.25x the all-items rise, by our arithmetic.
Compounding the seasonally adjusted monthly changes from April through October, electricity is up 2.7% over those seven months against 2.2% for all items, by our arithmetic from the BLS table. The index for all items less food and energy rose 0.3% in October, as it did in September and August, the agency said.
Business Pill · Grid Cost Allocation
An evergreen Business Engineer explainer on who pays for grid costs. It teaches the general idea only and does not discuss the October CPI release.
The key insight: US consumer prices rose 0.4% in October on a seasonally adjusted basis, and the electricity index rose 0.9%, 2.25x as fast, by our arithmetic from the BLS release of 10 November. Compounded from April through October, electricity is up 2.7% against 2.2% for all items. BLS could not publish most 12-month rates because it did not collect October 2025 data.
BLS said the shelter index rose 0.3% in October, “accounting for over thirty percent of the monthly all items increase”. The food index rose 0.5%, with food at home up 0.4% and food away from home up 0.5%. The energy index rose 0.7% after a 5.2% increase in September; gasoline rose 1.0% after 9.1%, and the natural gas index fell 0.8%.
The index for used cars and trucks declined 1.2% and the communication index fell 0.1%, BLS said. Recreation rose 0.8%, motor vehicle insurance 0.7% and medical care 0.3%.
As we reported on 9 November, the release carries no 12-month rate for most series. BLS said it “did not collect survey data for October 2025 because of a lapse in appropriations” and so “cannot publish 12-month percent changes for October 2026 for indexes where October 2025 data are unavailable”.

OCTOBER’S ๐บ๐ธ CPI:
What got cheaper: โข Coffee: -3.6%, largest monthly drop on record โข Distilled spirits (ex whiskey): -1.5%, record decline โข Used cars: -1.2%, biggest drop since January
What got pricier: โข Lettuce: +7.9% โข City bus & train fares: +6.6% โข Newspapers & magazines: +4.5% โข Women’s dresses: +3.7% โข TVs: +3.3% โข Food overall: +0.5%, biggest rise since April โข Groceries: +0.4%, biggest rise since April โข Dining out: +0.5%, biggest rise since December
Wall St Engine listed October’s month-over-month CPI movers on 10 November: coffee down 3.6%, which it called the largest monthly drop on record, TVs up 3.3%, used cars down 1.2% and food up 0.5%. The coffee, TV, used car and food figures match the BLS release and Table 2 this piece is built on; the record claim is the poster’s.
The Technology Lines
In the detailed BLS Table 2, the seasonally adjusted index for televisions rose 3.3% in October and computers, peripherals and smart home assistants rose 0.5%. Computer software and accessories fell 1.5%, and internet services and electronic information providers fell 0.5%. Information technology commodities as a group rose 0.4%, the same as all items.
Coffee fell 3.6% in the same table. Wall St Engine called it the “largest monthly drop on record”; we have not checked the full series history.
Electricity and the Data Center Question
Electricity has a relative importance of 2.513 in the September 2026 basket, BLS Table 2 shows, about one fortieth of the CPI, by our arithmetic. On the same day, we reported that in the Energy Information Administration’s 10 November outlook, the commercial sector, which EIA says includes data centers, accounts for 64% of the rise in US retail power sales from 2025 to 2027. BLS does not attribute household electricity prices to data center demand, and neither release links the two.
The CPI data arrived the same day Dallas Fed President Lorie Logan said the Federal Reserve needs at least two more quarter-point rate increases, as we reported. A day earlier, the Reserve Bank of Australia’s Sarah Hunter said AI is lifting demand before it lifts supply, as we reported.
The Structural Read
As we read it, the October release puts household electricity among the faster-rising major CPI lines, at 0.9% against 0.4% for all items. BLS does not attribute the increase to data center demand, so that link is not established by these figures.
US Bureau of Labor Statistics, Consumer Price Index – October 2026, 10 Nov 2026
“The index for electricity rose 0.9 percent over the month.”
Three Implications
FOR HOUSEHOLDS Electricity has a relative importance of 2.513 in the September 2026 basket, about one fortieth of the CPI, by our arithmetic from BLS Table 2.
FOR THE RATE DEBATE Dallas Fed President Lorie Logan said on 10 November that the Federal Reserve needs at least two more quarter-point rate increases, as we reported; core CPI rose 0.3% in October, BLS said.
FOR AI POWER DEMAND In EIA’s 10 November outlook, the commercial sector, which EIA says includes data centers, accounts for 64% of the rise in US retail power sales from 2025 to 2027, by our earlier arithmetic.
The framework says: “Companies that solve the power equation will dominate the AI era; those that don’t will watch their chips sit idle.”
As we read it, the CPI electricity line is the household side of that power equation. The framework predates the October release and does not discuss consumer prices.
What Is Not Established
The release gives no 12-month inflation rate for most series, so October’s annual pace is not established from BLS data. Whether data center demand is behind the electricity increase is not established: BLS does not say, and EIA does not break out data centers. BLS notes that indexes for the past 10 to 12 months are subject to revision. The record claim for coffee is Wall St Engine’s, not BLS’s.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
US consumer prices rose 0.4% in October and the core index 0.3%, BLS said. Electricity rose 0.9%, 2.25x the headline, and is up 2.7% since March against 2.2% for all items, by our arithmetic. The agency could not publish 12-month rates for most series because of the October 2025 data gap.
A note on sourcing. Index changes and quotations come from the US Bureau of Labor Statistics’ October 2026 CPI release and its Table 2, published 10 November 2026; the coffee record claim is Wall St Engine’s. Ratios and compounded changes are our arithmetic.
