US consumer prices climbed 0.4% in October on a seasonally adjusted basis, exceeding economist expectations of 0.3%, according to the Bureau of Labor Statistics. Core inflation, which strips out volatile food and energy costs, also surprised to the upside at 0.3% against a forecast for 0.2%. The figures mark a significant shift from September, when headline inflation had risen 0.6% and core had advanced 0.3%.
The stronger-than-expected report has shifted thinking about the Federal Reserve's interest-rate path. Fed Governor Christopher Waller said Tuesday that a hot inflation reading could push him to support a half-percentage-point rate increase in December, specifically if core CPI was around 0.3%. Following the release, financial markets fully priced in a quarter-percentage-point increase when the Fed meets December 8-9, with odds of a half-point hike jumping to 13.6% from near zero before the report, according to the CME Group's FedWatch tool. Dallas Fed President Lorie Logan said she sees a need for two additional quarter-point increases and warned that the personal consumption expenditures price index, the Fed's primary inflation gauge, could also move higher when reported later in November.
Broad-based price pressures drove the increase. Energy costs rose 0.7%, with gasoline up 1%, while food accelerated 0.5%, driven by snacks up 1%, beef up 0.9%, and meats, poultry, fish and eggs up 0.5%. Shelter costs, which accounted for more than 30% of the headline increase, rose 0.3%. Transportation services jumped 0.8%, though used cars and trucks fell 1.2%. Electricity prices rose 0.9%, reflecting pressures from hyperscaler spending in the artificial intelligence buildout.
Fed officials have flagged concerns that geopolitical and trade factors are becoming embedded in the economy. Despite moderating gasoline prices in recent weeks, Fed policymakers worry that impacts from the Iran war and tariffs are taking hold. Inflation has been running above the Fed's 2% target for approximately five and a half years. The report comes as the Fed at its October meeting voted 10-2 to hold its benchmark rate in a range between 3.75% and 4%.
The inflation data coincides with signs of sustained pricing power in the economy. Retail sales rose 0.8% in September, according to the Commerce Department, and a net 37% of businesses surveyed in the October National Federation of Independent Business survey said they plan to raise prices in the next three months, the highest level since July 2022.
For Americans managing debt and savings, higher inflation and the prospect of more rate increases means borrowing costs will likely rise further while the purchasing power of cash held in savings accounts may face continued pressure despite improved yields.
