🇺🇸October consumer prices rose 0.4% month over month; core prices increased 0.3%, both exceeding expectations.

The reported October Consumer Price Index (CPI) increase was 0.4% month over month, compared with a 0.3% forecast and 0.6% in the previous month. Core CPI increased 0.3%, against a 0.2% forecast, matching the previous month’s increase.

The distinction is between slower headline inflation than in September and an upside surprise relative to expectations. Neither monthly reading should be treated as a year-over-year inflation rate.

Before the release, Federal Reserve Governor Christopher Waller said a 50-basis-point December increase might be needed if October core CPI came in around 0.3% or higher. Later coverage quoted Chicago Fed President Austan Goolsbee expressing concern about persistent services inflation and saying AI construction was adding demand; these were policymakers’ assessments, not a new Federal Reserve rate decision.
