Says FX stability is extremely important

I've said this before, but ICYMI, when a Japanese official (and they don't come any bigger than the PM) comments on wanting stable exchange rates he (or, rarely, she) means he wants the yen to stop rising.

USD/JPY fell hard overnight. It was mainly a USD move but still - they are such yen snowflakes in the Japanese administration and it doesn't take much to trigger them.
