FX_IDC:JPYUSD   Japanese Yen / U.S. Dollar
The Yen v Dollar having already started the plunge out of a very long term head an shoulders move with resistance confirmed is now at the bottom of a descending triangle pattern. A failure to reverse this pattern and go lower could mean a dramatic slide in the Yen.
It is not surprising that the Japanese Central Bank announced a rate hike.
Generally everything they have ever done has been completely ineffective so I wouldn't bet on them achieving what they want.
This also could cause an Asian crisis in world markets.
