BERLIN- The mood among German investors slid far more than expected in August, a survey showed on Tuesday, and the ZEW institute blamed trade disputes and higher chances of a no-deal Brexit for a worsening outlook in Europe's biggest economy.

ZEW said its monthly survey showed economic sentiment among investors fell to -44.1 from -24.5 in July. Economists polled by Reuters had expected a drop to -28.5.

A separate gauge measuring investors' assessment of the economy's current conditions fell to -13.5 from -1.1 in the previous month. Analysts had predicted a reading of -7.0.
