Back to 122.44

USD/JPY is all over the place as the market digests the shock BOJ easing announcement.

It shot up to 123.50 but has plunged to a session low of 122.34 now. It doesn't make any sense for USD/JPY to be selling off here with the BOJ announcing fresh easing.

The details of the maturity extension and ETF buying are still leaking out.
