US producer prices rose 0.3% in October, marking the largest annual gain since November 2022. The Labor Department said the 6.5% yearly increase followed a 1.4% surge in September. Higher costs for food and chemicals pushed these figures up, fueling expectations that the Federal Reserve could continue raising interest rates.

WASHINGTON, Nov 13 (Reuters) - US producer prices increased further in October, leading to the largest annual gain in four years ​and supporting expectations that the Federal Reserve ‌could continue raising interest rates after next month's widely expected hike.

The Producer Price Index for final demand rose 0.3% last month ​after an upwardly revised 1.4% surge in September, the ​Labor Department's Bureau of Labor Statistics said ⁠on Friday. Economists polled by Reuters had forecast the ​PPI climbing 0.4% after vaulting 1.3% in September.

Producer prices ​last month were lifted by a 0.5% rise in goods, mostly food and basic organic chemicals. Services increased 0.2%, advancing for ​the fifth straight month.

The PPI shot up 6.5% ​year-over-year in October, the largest annual gain since November 2022, after advancing 6.3% ‌in ⁠September.

The report followed news this week of a stronger-than-expected increase in consumer prices in October. Nonfarm payrolls surged in October and the unemployment rate dropped to 4.1% from ​4.2% in September, ​the government ⁠reported last week.

That, together with comments from US central bank Governor Christopher Waller, have ​left financial markets wavering between pricing in ​a ⁠25-basis-point rate hike in December and leaving room for half-a-percentage-point increase. Financial markets anticipated another increase in borrowing ⁠costs ​in January, CME's FedWatch tool ​showed. The Fed left its benchmark overnight interest rate in the 3.75%-4.00% range ​last month.
