Oil Is Sinking, Core Inflation Isn't, and the Fed Is Out of Good News
Saudi output is back near pre-war levels and Brent sits at two-month lows, but October core CPI still beat forecasts. Waller's warning about a half-point December hike shows where the debate now lives.
October inflation delivered a split verdict. Headline CPI rose a seasonally adjusted 0.4%, above the 0.3% Dow Jones consensus, and core CPI came in at 0.3% against a 0.2% forecast, according to the Bureau of Labor Statistics. The core figure marked the third consecutive month at that pace.
The odd part is that the usual excuse is vanishing. Oil supply is back near where it stood before the Iran war began, and Brent crude has slid to its lowest levels in two months. Yet the price of everything that is not energy refused to soften, and that is reshaping the Federal Reserve's December calculus in real time.
Fed Governor Christopher Waller put the stakes on the table hours before the data dropped, speaking in London. He said he will support a quarter-point hike in December even if October's numbers improve, but if core inflation runs around 0.3% or higher, "a 50 basis point hike in the policy rate should be considered," warning that "Hiking only 25 basis points would put our credibility at risk." CME FedWatch now shows the quarter-point hike fully priced for the December 8-9 meeting, with the odds of a half-point move at 13.6% after sitting near zero before the report.
The energy half of the problem is solving itself
OPEC's November monthly report shows Saudi Arabia told the group it is pumping 10.563 million barrels per day of crude in October, up more than 2 million bpd from September and the highest since the Iran war began in late February. OPEC+ as a whole produced 41.23 million bpd, up roughly 2.04 million bpd and about 97% of the group's pre-war level of 42.72 million bpd. With peace talks under way on both the Iran and Ukraine fronts, Brent futures fell $1.14, or 1.2%, to $91.62 a barrel early Thursday, after touching two-month lows earlier in the week.
That should be doing the Fed's work for it. Instead, the October CPI basket showed the energy index up 0.7% on the month, with gasoline rising 1% and electricity climbing 0.9%, while food added 0.5%. Wholesale crude has been easing for weeks, yet the price tags inside the report have not followed. Natural gas did fall 0.8%, and used car prices dropped 1.2%, the rare outright declines in the data.
The domestic half refuses to cooperate
Strip energy out and the picture hardens. Shelter rose 0.3% and accounted for more than 30% of the headline increase. Transportation services jumped 0.8%, and airline fares added 0.4%. The pressure is still building upstream too: a net 37% of small businesses in the October NFIB survey plan to raise prices in the next three months, the highest reading since July 2022.
Waller's London speech carried a caveat against reading falling crude as a cure-all. New Fed research, he said, suggests core inflation may be more responsive to energy shocks since the pandemic, meaning the recent relief at the pump could feed into the core basket with more force than history would suggest. The same research flags energy pressures persisting well into 2027, notes diesel is constrained by limited refining capacity, and cites insurance and ship-to-ship transfer costs for Gulf shipping that are reportedly adding $20 to $30 a barrel to oil prices. Falling crude, in that reading, is a less reliable guide to the core basket than it used to be.
The credibility math for December 8-9
The recent inflation record gives Waller's warning its bite. September PCE inflation rose 0.5% on the month and 3.7% over 12 months, with core PCE at 0.3% and 3.1%, and more than 70% of the components of core PCE services prices posted 12-month increases above 3%. Inflation has now run above the Fed's 2% target for roughly five and a half years. Against that backdrop, the October meeting ended 10-2 to hold the benchmark rate at 3.75%-4%.
Dallas Fed President Lorie Logan said she sees a need for two additional quarter-point increases before a pause, and added that "It may be possible to move more rapidly this winter than the [FOMC] has moved so far this fall." Philadelphia Fed President Anna Paulson pointed to tariffs, energy prices and the AI buildout as forces keeping inflation elevated, saying "further gradual tightening seems appropriate."
One quirk of this cycle: the BLS could not publish a year-over-year figure for October because last year's government shutdown prevented collecting October 2025 data, so the market is judging the print entirely on monthly momentum. That momentum sits on an economy that is not exactly begging for relief. Real GDP grew 3.4% in the third quarter on the initial estimate, unemployment ticked down to 4.1% in October, payrolls added 165,000 workers, and September retail sales rose 0.8%.
So the December meeting now turns on the domestically generated half of the inflation problem: whether the shelter and services core that has run at 0.3% for three straight months justifies moving faster than a committee that spent October holding rather than hiking. Waller has answered that question in public. The other 11 voters have until December 8 to decide whether he is right.
