BRUSSELS (Reuters) - Industries across the euro zone cranked up output in November and Germany ended the year with its strongest growth in five year, data showed on Thursday, pointing to an economic spurt that may be arriving earlier than some ECB policymakers expect.
Euro zone industrial output in the 19-country currency bloc surged 1.5 percent on the month and 3.2 percent year-on-year as firms stepped up production before Christmas. Both figures were far better than expected.
That gelled with a surprisingly large increase in Italian industrial production, also reported on Thursday, and similarly robust numbers earlier this month from France.
The German statistics office, meanwhile, estimated growth in the euro zone largest economy was around 0.5 percent for the fourth quarter and expanded by 1.9 percent in 2016, the strongest rate in five years.
Economists said these figures added to the evidence that euro zone gross domestic product will have picked up in the last quarter of last year.
The numbers are also relatively unexpected. Indeed, investment bank Citi ranked the euro zone at the top of its Economic Surprise Index at year-end, higher even than the rating for Britain's unforseen post-Brexit performance.
The strong rise of industrial output "reinforces our belief that euro zone GDP growth could well have reached 0.5 percent quarter-on-quarter in the fourth quarter of 2016," said Howard Archer, economist at IHS Global Insight.
Euro zone GDP grew a modest 0.3 percent in second and third quarter of last year, after a 0.5 percent rise in the first quarter.
Thursday's figures add to a jump in the bloc's economic sentiment which in December reached its strongest level since March 2011.
Euro zone consumer confidence also hit a 20-month high in December and has been rising for four consecutive months, European Commission's estimates showed.
Monthly retail sales in the bloc did fall by 0.4 percent in November but only after a rise by 1.4 percent in October, by far the largest in years.
The surprising burst in economic activity may fire up criticism from economists and politicians in countries such as Germany that the European Central Bank is hanging on too long to its ultra-easy monetary policy, including asset purchasing.
The ECB, however, remains cautious about the outlook and will need sustained evidence before it moves.
Indeed, the improved outlook for the last quarter of the year may however not carry over to 2017 in part because it brings with it an increase in prices.
"We expect rising inflation to weigh on consumer spending growth, causing overall GDP growth to slow in 2017," Jack Allen of Capital Economics said.
Euro zone consumer inflation in December was 1.1 percent, the highest level since September 2013, as oil prices are going up. It remains under the roughly 2 percent target sought by the ECB, however.
In addition, the November euro zone industrial output data confirmed caution is still prevailing among firms, as political uncertainty over the coming months restrains investment.
The monthly output rose strongly for non-durable consumer goods, such as clothing or foodstuff, a sign that companies were betting on more consumption ahead of the Christmas shopping.
Production grew markedly on the month also for intermediate goods and energy, but it rose only slightly for capital goods, like machineries, a sign of only limited appetite for long-term investment.
Output of durable goods, such as cars or refrigerators, was the only component of the indicator to record a drop, by 0.1 percent on the month, confirming firms' cautious approach as consumers were less keen to purchase more expensive items.
