Given your post count, I am surprised you don't understand the basic concept that prices usually go up before they go down.
Anyway, there are idiots still shorting jpy. They think they are getting on the trend. The bankers are giving them more rope to play. The big jpy rise relative to eur and aud is still in the pipelines. Can't really say if the bankers are going to use the BS fed speech later today as a vehicle to carry jpy higher. It remains a possibility because the bankers rarely let a weekend past without giving some people the needed soul searching thinking time.
