The Yen was over 98 to 1 AUD about a week and a half ago, not seen since late 2014, but dropped dramatically on Thursday after the Japanese government intervened by buying yen, something it hasn't done since 1998. Consequently, the rate has fallen to about 93. 93 is still pretty good but it looked like it was going to break 100. Analysts believe the effect will be temporary and the yen will weaken further.
