GBP review: Western Union

Quotes from Western Union:

- Sterling bled some of its recent appreciation on caution ahead of this week's key testimony by the Fed chair. The pound is hot off its strongest levels in six weeks against the greenback and six years overall. 

- Better data from the U.K. of late has hinted at strengthening momentum in the economy. Sterling made its 2015 debut against the dollar near $1.56 so purchases below that level amount to sensible buys for U.S. importers.
