So how to do it (talk the currency down) effectively?
I've got some ideas on what they might try ... but lets hear from ForexLive.
Over to you - in the comments please ladies and gentlemen!
(ps. Meanwhile, USD/JPY slips back below the sandy line of 115 .... or blurred line I should say. Currently 114.96 as I update)
