With all the excess "liquidity" force down everyone's throat, the world over, this carry trade is no exception. This pair can move 10k pips in a heartbeat when 'it' hits the fan (which ought to be sooner than later). On the long run (full cycle) the NZD is not worth 50 yen! (It is actually much closer to 30, after all is said and done.) With a "live" BoJ meeting expected at the end of this month, all these trades could kick into high gear (trap door), in an instant.
