USD/JPY is up 200+ points from its lows seen during Asia back on Friday.
You might recall we had comments from Japanese Ministry of Finance officials about FX 'stability', which I decoded for you as meaning they were concerned about the p[ace at which the yen was gaining. They'll be much happier now, right? ;-)
Nikkei is higher too, the index tends to benefit from a lower yen.
EUR, AUD, GBP, NZD all lower against the USD, also following their their Friday moves.
