Inflation Ran Hot. A December Fed Hike Just Got Likelier.
October CPI beat forecasts: prices up 0.4%, core up 0.3%. With markets already pricing a December Fed hike, here's what the hot reading means and which stocks feel a hike first.
Nov 10, 2026: October CPI came in hot. Prices rose 0.4% for the month against a 0.3% forecast, and core prices rose 0.3% against 0.2%. That is the "hot" scenario below, which keeps a December rate hike firmly on the table. No yearly rates were published this month.
Quick Read
Markets see about an 80% chance of a Fed rate hike in December 2026, at the Dec 8-9 meeting, per CME FedWatch as of Nov 8. The Fed already raised rates in September to a 3.75% to 4% range, its first hike in about three years, and held in October.
The October CPI report, released Nov 10, was the biggest test of that view. Prices rose 0.4% for the month (forecast 0.3%, after 0.6% in September) and core prices 0.3% (forecast 0.2%).
A hike matters for holders beyond bonds. Higher rates tend to weigh most on high-growth stocks, small companies with floating-rate debt, homebuilders, and heavy borrowers.
A Fed rate hike in December 2026 is now the base case
Most investors spent 2025 waiting for rate cuts. In 2026 the question flipped. The Federal Reserve raised its benchmark rate by a quarter point on Sept. 16, in a unanimous vote, and held it at 3.75% to 4% on Oct. 28. Two officials dissented in October because they wanted another hike right away.
Then Friday's jobs report came in hot: 165,000 jobs against about 59,000 expected, and unemployment fell to 4.1%. The 10-year Treasury yield rose to 4.86%. By Sunday, futures priced about an 80% chance the Fed raises again in December; other gauges put it nearer 70%. Stocks rebounded on Monday, with the Nasdaq up 2.7% as oil slid, but the rate question did not go away.
The Fed in 2026 | What happened |
|---|---|
Sept. 16 | Raised rates 0.25 point to 3.75%-4%, a unanimous vote |
Oct. 28 | Held at 3.75%-4%; two officials voted to hike |
Nov. 6 | Jobs: 165,000 vs 59,000 expected; unemployment 4.1% |
Nov. 8 | Futures: about 80% odds of a December hike |
Dec. 8-9 | Next Fed decision |

What the October CPI report needs to show
The Consumer Price Index (CPI) measures how fast prices rise for everyday goods and services. "Core" CPI strips out food and energy, which swing a lot, so the Fed watches it closely.
September was hot on the surface. Prices rose 0.6% for the month and 3.7% from a year earlier. Gasoline alone, up 9.1% in the month, drove more than half of that jump. Core inflation was calmer at 2.6% a year, though still above forecasts.
CPI | August | September | October actual (forecast) |
|---|---|---|---|
Headline, month | 0.4% | 0.6% | 0.4% (0.3%) |
Headline, year | 3.4% | 3.7% | Not published* |
Core, month | 0.3% | 0.3% | 0.3% (0.2%) |
Core, year | 2.4% | 2.6% | Not published* |

Oil fell about 13% last week, but most of that came in November. October's report still reflects the high fuel prices of the autumn. That is why core mattered most: it tells the Fed whether price pressure is spreading beyond the gas pump. It came in at 0.3%, so the answer leaned yes. The Cleveland Fed's nowcast had pointed to about 0.24% for prices and 0.21% for core. One quirk: this report showed monthly changes only, so the month-on-month core number carried all the weight.
Three ways Tuesday could go, and where it landed
If October CPI comes in... | What it likely means for the Fed | Where investors tend to feel it |
|---|---|---|
Hot: core 0.3% or more | December hike close to locked in | Yields up; pressure on growth and small-cap stocks |
In line: core about 0.2% | Hike still likely; the jobs report keeps it alive | Little change; Friday's producer prices matter more |
Cool: core 0.1% or less | Odds of a hike fall sharply | Yields down; relief for rate-sensitive stocks |

October landed in the first row: core rose 0.3%. These are tendencies, not rules. Markets often move on the details, like shelter costs or services prices, more than on the headline number.

How a rate hike hits different stocks
A rate hike does not hit every stock the same way. It helps to know which parts of a portfolio carry the most rate risk.
High-growth and AI stocks. Their value rests on profits years away. Higher rates make those future profits worth less today. Last week's AI selloff already showed how much growth is priced in.
Heavy borrowers. Companies that fund growth with debt pay more as rates rise. CoreWeave (CRWV), which reports Tuesday after the close, guided third-quarter interest expense to $860 million to $940 million. In the second quarter it paid $640 million, up from $267 million a year earlier.
Small companies. Many carry floating-rate loans, so a hike shows up in their costs quickly.
Homebuilders. Mortgage rates follow the 10-year yield, now near 4.86%, which weighs on buyers.
Banks. Mixed: higher rates can lift lending margins, but they also slow loan demand and raise credit risk.
None of this is new on its own. What's new is the direction. After years of hoping for cuts, many portfolios were built for falling rates.
The bull case and the bear case for stocks
The bull case. A hike to fight inflation in a strong economy is a different story from a hike into a weak one. Hiring just beat forecasts by more than 100,000 jobs. If core inflation cools in the coming months, December's hike may be the last, and markets often rally once the end of a hiking cycle comes into view.
The bear case. Stocks are still near high valuations, and the AI trade just showed how fast sentiment can turn. October's hot CPI raises the risk of the 10-year yield pushing toward 5%, which would raise borrowing costs across the economy and pressure the most expensive stocks at the same time.
What to watch this week
The rest of Tuesday: how Treasury yields and December hike odds settle after the hot print.
Tuesday after the close: CoreWeave earnings, the first big AI test since the selloff.
Thursday, Nov. 12: Cisco (CSCO) and Applied Materials (AMAT) earnings; weekly jobless claims.
Friday, Nov. 13, 8:30 AM ET: October producer prices (PPI), forecast 0.4% after 1.3%.
All week: a long list of Fed speakers, including Waller, Logan, Williams and Daly.
