The U.S. dollar index .DXY fell on Friday morning to its lowest since March 26 after the Labor Department's employment report showed that job growth slowed sharply in May and wages rose less than expected. The weak data suggest that the loss of momentum in economic activity has spread to the labor market, which could increase expectations that the Federal Reserve will cut interest rates this year. Rising expectations of a cut have pulled the dollar 1.2% lower this week.
