"The financial market experts are optimistic about the future. They are confident that the German economy will be back on the growth track within the next six months," ZEW President Achim Wambach said in a statement.

"Consumption and retail trade in particular are expected to recover significantly, accompanied by higher inflation expectations," he added.
