EUR review

Western Union notes:

The euro lost some of its resilience as mounting unease over Greece helped steer nervous investors toward alternative currencies like the pound. 

Sterling's outperformance against the euro translated into gains against the dollar. Healthier U.K. inflation also buoyed the pound. 

Adding to the euro's weaker tone, Germany's ZEW index of investor optimism darkened more than expected to 31.5 in June from 41.9 in May which was the weakest level since November. 

Pullbacks in the euro have proven short-lived of late as markets have loosened ties to the dollar given America's growth setback to start the year which has muddied the outlook for higher U.S. interest rates.
