Markit Economics released construction purchasing managers' index (PMI) for Germany on Monday. Germany's construction PMI decreased to 52.7 in May from 53.4 in April.

A reading above 50 indicates expansion in the sector.

The index was mainly driven by a softer growth in output and new orders.

"The upturn in Germany's building sector lost further momentum in May, with companies reporting the weakest expansion of construction activity for half a year," an economist at Markit, Oliver Kolodseike, said.
