Inflation at the wholesale level rose 8.6% last month from a year earlier, matching September’s record annual gain and offering more evidence that inflationary pressures are not yet easing.

The Labor Department reported Tuesday that its producer price index — which measures inflation before it hits consumers — rose 0.6% last month from September. Excluding volatile food and energy prices, wholesale inflation was up 0.4% in October from September and 6.8% from a year ago.

More than 60% of the September-October increase in overall producer prices was caused by a 1.2% increase in the price of wholesale goods as opposed to services.
