U.S. inflation runs hotter than expected in October; December rate hike looks likely

Prices in the United States rose faster than expected in October. The Consumer Price Index, the government's main measure of inflation, climbed 0.4 percent from September, according to the Bureau of Labor Statistics report released on Tuesday, November 10. Economists had expected 0.3 percent. The result strengthens the case for another interest rate increase by the Federal Reserve in December.

The main numbers

• Headline CPI (all items): up 0.4 percent in October, after 0.6 percent in September. Forecast: 0.3 percent.
• Core CPI (excluding food and energy, which economists watch most closely): up 0.3 percent, the same as in August and September. Forecast: 0.2 percent.

Both numbers came in one-tenth of a point above expectations. That may sound small, but a 0.3 percent monthly rise in core prices works out to roughly 3.6 percent a year if it continues, well above the Federal Reserve's 2 percent target.

No official yearly number this time

Normally the report also shows how much prices rose over the past 12 months. This month, the Bureau of Labor Statistics did not publish that figure for most categories, because it could not collect October 2025 prices during last year's government shutdown. Without last October's prices, there is nothing official to compare against.

Some economists have produced estimates. Bank of America, for example, estimates yearly inflation at about 3.8 percent for all items and 2.7 percent for core. These are private estimates, not official figures. For comparison, the last official yearly numbers, for September, were 3.7 percent overall and 2.6 percent for core.

What went up, and what went down

According to the government report (seasonally adjusted, month over month):

• Energy rose 0.7 percent, after a 5.2 percent jump in September. Electricity rose 0.9 percent.
• Gasoline rose 1.0 percent on the government's seasonally adjusted basis. Before that adjustment, pump prices actually fell 0.7 percent; the adjustment accounts for prices that usually drop more in October.
• Food rose 0.5 percent. Groceries were up 0.4 percent, and restaurant meals up 0.5 percent.
• Shelter (housing costs), the biggest single part of the index, rose 0.3 percent, after 0.4 percent in September. Rent rose 0.2 percent.
• Car insurance rose 0.7 percent, and recreation 0.8 percent.
• Airline fares rose 0.4 percent, after 1.2 percent in September.
• Used cars and trucks fell 1.2 percent, one of the few categories that got cheaper.

Why it matters for interest rates

The Federal Reserve is already in rate-raising mode. It raised its key rate by a quarter point on September 16, then held it steady at a range of 3.75 to 4.00 percent on October 28. That October decision was not unanimous: two officials, Governor Lisa Cook and Cleveland Fed President Beth Hammack, voted for another increase right away. The Fed's statement said "inflation remains elevated."

Fed officials have said they are worried that inflation, first pushed up by tariffs and the war with Iran, is proving more stubborn than expected. October's report gives them little reason to relax. Last Friday's strong jobs report had already pushed market bets on a December hike higher.

After the CPI release, traders' bets on a quarter-point rate increase at the Fed's next meeting, on December 8 and 9, stood above 80 percent, according to the CME FedWatch tool, which tracks prices in futures markets. A rate increase would make mortgages, car loans and credit card debt more expensive.

How markets reacted

Updated Tuesday morning with the confirmed market reaction.

• Bonds: the 10-year Treasury yield, which sets the tone for mortgage rates, jumped by more than 7 basis points (0.07 percentage point) to about 4.94 percent. Shorter-term yields also rose.
• Dollar: the U.S. dollar strengthened, with the dollar index up about 0.3 percent, near 102.
• Stocks: futures pointed lower. S&P 500 futures fell about 0.5 percent and Nasdaq-100 futures about 1.2 percent, while Dow futures were roughly flat. Higher borrowing costs tend to hit technology stocks hardest.

Adding to the pressure, Federal Reserve Governor Christopher Waller said hours before the report that a larger, half-point (0.50 percentage point) increase should be considered at the December meeting, instead of the usual quarter point. Waller's comments and the hotter inflation numbers together pushed bond yields higher.

Markets can change quickly through the day, so early moves do not always last.

What it means for your wallet

For households, the picture is mixed. Gas prices at the pump have been easing in November as oil prices fall, and used cars are getting a little cheaper. But food, housing, electricity and car insurance keep climbing month after month, and those are costs most families cannot avoid. If the Fed raises rates again in December, borrowing will also get more expensive, especially for anyone with a variable-rate loan or credit card balance.

What to watch next

• The Producer Price Index, which tracks the prices businesses pay and often hints at where consumer prices are heading.
• Comments from Fed officials before their quiet period starts ahead of the December meeting.
• The November CPI report, scheduled for December 10, the day after the Fed's decision.
• The Fed's decision on December 9.
