The ZEW economic sentiment index for the 17-nation euro zone, which gauges the six-month economic outlook, rose sharply to 58.6 in September, significantly up from the 44 points recorded in August and beating analysts' expectations of a reading of 46 for the month.
The ZEW index for Germany increased by 7.6 points to hit 49.6 points in September, up from the 42 points registered in the previous month. Analysts had expected a reading of 46 points.
"The financial market experts hold the view that the German economy is still gaining momentum. In particular, the experts’ economic optimism has increased due to the improved economic outlook for the euro zone -- although recently released economic data for Germany have fallen short of expectations," ZEW President Clemens Fuest said, in a statement.
