Euro zone producer prices fell more than expected in October, data showed on Tuesday, with the annual inflation rate at a nearly 4-year low in a fresh sign of a sharp fall in inflationary pressures.
Prices at factory gates in the 17 countries using the euro declined 0.5 percent in October against September, the EU's statistics office said on Monday, the first monthly decline in five months.
Economists polled by Reuters had forecast a decrease of 0.2 percent.
Changes in producer prices, unless absorbed by retailers, eventually translate into changes in the consumer price index, which the European Central Bank wants to keep below, but close to 2 percent. Consumer inflation was 0.9 percent year-on-year in November.
The year-on-year figure for producer prices showed a 1.4 percent drop in October, its lowest since December 2009, after a 0.9 percent fall in September.
The monthly drop was strongly driven by a 1.4 percent fall in costs or energy, followed by a 0.2 percent decrease in prices of non-durable consumer goods.
Prices in only three countries of the bloc - Estonia, Cyprus and Malta - were flat or rising on the month in October and the annual reading was in the positive territory only in Estonia, Ireland, Malta and Finland.
France, the euro zone's second largest economy saw a 0.3 percent drop on the month, putting the annual rate at -1.4 percent, its lowest since December 2009, according to the Eurostat data.
