Euro zone producer prices fell by more than expected in January, pulled down by plunging costs of energy, data from the European Union’s statistics office Eurostat showed on Tuesday. Eurostat said prices at factory gates in the 19 countries using the euro fell 0.9 percent month-on-month in January for a 3.4 percent year-on-year fall. Producer prices are an indication of inflationary pressures in the economy early in pipeline as the rise or fall of prices at factory gates usually translates into higher or lower prices for consumers, unless the change is absorbed by intermediaries.
