Market research group Sentix released its investor confidence index for the Eurozone on Monday. The index fell to 5.5 in March from 6.0 in February. It was the lowest level since April 2015.

A reading above 0.0 indicates optimism, below indicates pessimism.

"The Eurozone suffers from the loss of economic momentum of the global economy," managing director at Sentix, Patrick Hussy, said.

"A look abroad gives more reasons to cheer this time: values for Asia ex. Japan could recover the second month in a row. Moreover, the US economy exhibits resilience in March," he added.

The current conditions index fell to 8.3 in March from 10.5 in February.

The expectations index climbed to 2.8 in March from 1.5 in February.

German investor confidence index rose to 16.9 in March from 14.5 in February.
