USD review: Western Union

The dollar added to its weekly advance and was set for its best quarter on record versus the euro and its best overall quarter since 2008. The dollar strengthened to 12-year highs in mid-March thanks to an outlook calling for higher U.S. interest rates and low to lower ones abroad. 

Meanwhile, uncertainty related to Greece is also translating into support for the greenback. Relatively low U.S. Treasury yields suggest a good chunk of the dollar's early week gains stem from Greece's unstable fiscal footing. 

The dollar will be put to the test on Friday when U.S. nonfarm payrolls come due. Forecasts call for monthly job growth of around 245,000. Considered one of the biggest market movers, the jobs data should shed clues on when the Fed might boost interest rates, which is sure to impact the dollar and broader currency markets.
