JPY review

Western Union notes:

Once again, fresh bouts of weakness for the yen have proven short-lived, repeating a pattern that has been in place for several months. 

Japan's central bank governor singlehandedly helped the yen up from 13-year lows hit last week after he told Japanese lawmakers that the yen's "very weak" state suggests weakness for now has run its course. 

A better week for the Japanese economy has also added to the yen's renewed buoyancy.
