Markit Economics released its retail purchasing managers' index (PMI) for Eurozone on Monday. Eurozone's construction purchasing managers' index (PMI) rose to 50.6 in May from 47.9 in April.

A reading above 50 indicates expansion in the sector, a reading below 50 indicates contraction.

Sales in Italy declined in May, while sales in Germany and France rose.

"The Eurozone Retail PMI moved into growth territory amid increases in sales across both Germany and France, although it was only the former where conditions improved more generally," an economist at Markit, Phil Smith, said.
