MANNHEIM, Germany Aug 12 (Reuters) - German analyst and investor morale fell to its lowest level in more than 1-1/2 years in August, a survey showed on Tuesday, suggesting Europe's largest economy is in for a rough ride in the third quarter.
Mannheim-based think tank ZEW's monthly survey of economic sentiment fell for an eighth consecutive month to 8.6 in August, its lowest since December 2012 and missing the consensus forecast in a Reuters poll for a reading of 18.2.
A separate gauge of current conditions tumbled to 44.3 from 61.8 in July, undershooting the consensus forecast for a reading of 55.5.
The index was based on a survey of 222 analysts and investors, and conducted between July 28 and August 11, ZEW said. (Reporting by Kirsti Knolle and Eva Taylor; Writing by Michelle Martin; Editing by Alexandra Hudson)
