USD fell against its major rivals in the European session on Friday as risk appetite improved, as investors focused on re-opening prospects, while fears of tighter policy in response to accelerating inflation were eased by Federal Reserve policymakers. 

The U.S. Dollar Index (DXY), measuring the U.S. currency's value relative to a basket of foreign currencies, dropped 0.34% to 90.45.

Investors also awaited U.S. data on retail sales and industrial production for April, due at 12:30 GMT and 13:15 GMT respectively, which are expected to provide more clues about the pace of the economic recovery.
