Hot October CPI Jolts Markets as Fed’s Waller Flags Possible Half-Point Hike in December
October inflation data came in hotter than expected Tuesday morning, just hours after Fed Governor Christopher Waller said he’d consider backing a 50-basis-point rate hike in December if core prices kept running at the pace they just did — a sharp reversal from the rate-cut talk of a year ago.
The Bureau of Labor Statistics’ October Consumer Price Index report, released at 8:30 a.m. ET Tuesday, showed headline prices rose 0.4% from September, versus the 0.3% economists surveyed by Dow Jones had expected, while core CPI (excluding food and energy) rose 0.3% for a third straight month, above the 0.2% consensus call. Shelter costs rose 0.3% and accounted for more than 30% of the month’s total increase, with owners’ equivalent rent also up 0.3% and rent of primary residence up 0.2%. Food prices rose 0.5% and energy climbed 0.7%, with gasoline up 1.0% on a seasonally adjusted basis after a 9.1% jump in September. Used cars and trucks fell 1.2%, one of the few categories to cool, while hospital services (+0.8%) and motor vehicle insurance (+0.7%) both ran hot.
A Missing Number Makes This Reading Harder to Judge
Notably absent from Tuesday’s release: a year-over-year inflation rate. The BLS said it will not publish 12-month percent changes for October 2026 in categories where comparable October 2025 data isn’t available, a gap tied to last year’s government shutdown, which disrupted data collection during that period. The annual figures are expected to return with the November report on December 10 — one day after the Fed’s next policy decision. The last official year-over-year readings, from September, put headline inflation at 3.7% and core at 2.6%, both still well above the Fed’s 2% target.
Waller’s Hawkish Pivot
Hours before the CPI release, Fed Governor Christopher Waller, speaking in London, said he was “leaning toward supporting an increase in our policy rate of 25 basis points” in December, but added a conditional warning: if the October data matched the past two months, with core inflation “around 0.3% or even higher,” then “a stronger policy move may be needed,” and “a 50 basis point hike in the policy rate should be considered at the December meeting.” He argued that holding to a quarter-point move under those conditions would “put our credibility at risk” — a risk he said he’s “not eager to take.” Waller also noted that core PCE inflation, the Fed’s preferred gauge, rose 3.1% over the year to September, calling that month’s data “bad” with “no silver lining.” Core CPI’s October print of 0.3% met the exact threshold he’d flagged. Waller is one of twelve voting members on the Federal Open Market Committee, and his comments followed an October 28 meeting at which the Fed held its benchmark rate steady at 3.75%–4.00% after raising it a quarter point on September 16 — with two officials, Lisa Cook and Beth Hammack, dissenting in favor of a hike at that meeting instead of a hold.
Markets React, Reversing Monday’s Rally
The hotter-than-expected print knocked stock futures lower Tuesday morning, with Nasdaq-100 tracker QQQ trading around $672, roughly 1% below Monday’s close, as traders repriced the odds of a larger December move, according to CNBC and StockTitan. The dollar strengthened and short-term Treasury yields moved higher following Waller’s remarks. The pullback came after major indexes closed sharply higher Monday, with stocks shrugging off governance headlines at Nvidia to post one of the market’s stronger sessions of the fall — a reminder of how quickly sentiment can swing on a single data point heading into the Fed’s final meeting of the year.
Why It Matters
A pivot from rate cuts toward a possible half-point hike would mark one of the sharpest policy reversals of the cycle, with direct implications for rate-sensitive sectors from AI infrastructure spending to crypto-mining economics. Investors tracking Nvidia and other AI-capex-linked names already have plenty to watch after this week’s governance turmoil at the chipmaker, and the same hawkish shift is weighing on crypto, where Bitcoin had already slipped below a key technical level over the weekend.
