The pair, however, witnessed a remarkable turnaround after the US Empire State Manufacturing Index and Producer Price Index printed better-than-expected readings for the month of May. Meanwhile, Canadian monthly Manufacturing Sales also witnessed a sharp rebound and printed a better-than-expected growth of 1%, but did little to boost the Canadian Dollar.
