The consumer price index, which is a basket of products ranging from gasoline and health care to groceries and rents, rose 6.2% from a year ago, the most since December 1990. That compared with the 5.9% Dow Jones estimate.

On a monthly basis, the CPI increased 0.9% against the 0.6% estimate.

Stripping out volatile food and energy prices, so-called core CPI was up 0.6% against the estimate of 0.4%. Annual core inflation ran at a 4.6% pace, compared with the 4% expectation and the highest since August 1991.

Fuel oil prices soared 12.3% for the month, part of a 59.1% increase over the past year. Energy prices overall rose 4.8% in October and are up 30% for the 12-month period.

Used vehicle prices again were a big contributor, rising 2.5% on the month and 26.4% for the year. New vehicle prices were up 1.4% and 9.8%, respectively.

Food prices also showed a sizeable bounce, up 0.9% and 5.3% respectively. Within the food category, meat, poultry, fish and eggs collectively rose 1.7% for the month and 11.9% year over year.

The price increases meant that workers fell further behind.

In a separate report, the Labor Department said real wages after inflation fell 0.5% from September to October, the product of a 0.4% increase in average hourly earnings that was more than offset by the CPI surge.

Shelter costs, which make up one-third of the CPI computation, increased 0.5% for the month and are now up 3.5% on a year-over-year basis, pointing to more reasons for concern that inflation could be more persistent than policymakers anticipate. The annual pace is the highest since September 2019.
