GBP review

Western Union:

The main cog that drives the U.K. economy grew at the fastest rate in months, news that offered some underpinning to sterling. Britain's services PMI rose more than expected to 58.9 in March for the best rate of growth since August 2014. 

A reminder of Britain's otherwise sturdy economic fundamentals can help slow the pound's daunting downside risk related to uncertainty in the run up to the country's national vote on May 7. 

Sterling strength should be held in check by receding expectations for a U.K. interest rate hike with inflation at record lows and showing no imminent sign of bottoming.
