German economic sentiment surged in July, with the ZEW index of investor expectations rising by 15.8 points to 26.3.
The jump marks a significant improvement in the outlook for the German economy over the next six months, reflecting a notable shift in market psychology.
Financial experts have grown more optimistic, driven by a combination of fiscal support and easing geopolitical tensions.
The rebound comes as markets digest a complex backdrop of de-escalating conflicts in the Middle East.
While the Ifo Institute recently upgraded its economic forecast for Germany, citing increased state expenditure and a cooling of tensions, the ZEW data suggests that private sector confidence is also recovering.
The improvement indicates that investors are beginning to price in a more stable environment, reducing the risk premium that has weighed on European equities and bonds.
