In brief
In October, the U.S. consumer‑price index increased more than analysts predicted, with core inflation persisting at a 3.6% annualized rate, well above the Federal Reserve's 2% goal. The spike pushed short‑term Treasury yields higher and created a market narrative that the Fed will raise rates in December, possibly by 50 basis points. Fed Governor Christopher Waller and economists from Natixis and Edward Jones discussed the implications of the new data.
October's U.S. consumer‑price index surged 0.4 percent, exceeding the 0.3 percent forecast, and core inflation—the subset of the CPI that excludes food and energy—rose 0.3 percent, translating to a 3.6 percent annualized rate. This persistent climb marked the third consecutive month of solid core inflation, prompting financial markets to assess the likelihood of tighter monetary policy in a December meeting of the Federal Open Market Committee.
The Bureau of Labor Statistics released the data on Tuesday, noting that shelter costs—such as rent and homeowner foreclosure costs—accounted for more than 30 percent of the monthly increase. The jump in core prices was seen as evidence that underlying price pressures remain stubborn, even as headline inflation recommendations note a broader range of goods.
Bond markets reacted swiftly, with the two‑year Treasury yield leaping approximately 15 basis points to above 4.7 percent, the largest single‑day rise since early April 2025. The 10‑year Treasury yield climbed to about 4.93 percent, reflecting an increased demand for higher rates to compensate for expected future tightening.
Fed Governor Signals Possible Rate Adjustment
During an overnight interview in London, Federal Reserve Governor Christopher Waller discussed the impact of October's readings on policy. He suggested that if core prices remain at 0.3 percent or higher, stronger action may be necessary and that a 50‑basis‑point hike could be considered in the December meeting.
"If core prices rose 0.3 percent or more, a stronger policy move may be needed," Waller said, adding that a 50‑basis‑point rate hike "should be considered at the Fed's Dec. 8‑9 meeting."
Waller’s comments aligned with the market’s reaction, which has now priced in a nearly certain rate hike in December, with the probability of a half‑percentage‑point increase rising to nearly 15 percent.
Economists Weigh in on Fed’s Next Move
Christopher Hodge, chief U.S. economist at Natixis North America, expressed concern about the third consecutive core inflation reading at 0.3 percent. He described the pace as "unacceptable" for the Fed and argued that a 50‑basis‑point increase in December is a strong possibility. Hodge also noted that if November’s print remains high, a larger, unexpected rate hike could occur.
"Even if markets are pricing 25 for December, if the November print is high, that could be a good time for a surprise jumbo hike," Hodge predicted.
In contrast, James McCann, senior economist at Edward Jones, suggested that while the data may seal a rate rise, the most likely tilt is a quarter‑point increase, noting that softer oil prices could temper the Fed’s urgency to fully tighten.
"The report most likely seals the deal on a hike to close the year, but a quarter‑point increase remains the most likely outcome as oil prices ease," McCann said.
These divergent views underscore the difficulty in translating CPI readings into precise policy actions, as the Fed must balance headline inflation trends against the risk of stifling economic growth.
For now, core inflation’s sluggish contraction suggests that the Fed will monitor market signals closely before committing to a definitive policy adjustment. The October data, coupled with Waller’s candid admission that a 50‑basis‑point move is on the table, sets the stage for a potentially decisive policy session in December.
