On the U.S. economic front, preliminary data released by the University of Michigan showed a continued slump by U.S. consumer sentiment in the month of April. The University of Michigan said its consumer sentiment index tumbled to 50.8 in April after plunging to 57.0 in March.

The report also said year-ahead inflation expectations surged to 6.7 percent in April from 5.0 percent in March, reaching the highest reading since 1981. A separate report released by the Labor Department showed an unexpected decrease by producer prices in the month of March.
