Among them, the index points of economic expectations dropped from 13.8 balance points last quarter to -0.1 balance points in the third quarter of this year.

"This signals an economic slowdown in the euro area," Ifo President Clemens Fuest stated in the report, based on the responses of 367 economic experts.

The economic climate deteriorated to varying degrees in euro area's five biggest economies including Germany, France, Italy, Spain and the Netherlands.

In addition, the surveyed experts expect investment to stagnate for the first time since the end of 2012. Meanwhile, they also forecast an annual inflation rate of 1.7 percent for 2018, 0.1 percent point higher than last year.
