DislikedMore food for thought......the yen is weighted at 13.60% against the USD. During his consolidation period from August 10, 2011 till today the yen has moved in a tight range of 100 pips ish........while the USDX (dollar index) has moved from its lows of 73.91 all the way up to 78.30. So you do the math....if the yen is weighted 13.60% against the moves of the US dollar and the yen has not moved at all during this very big move up on the US dollar......you have to ask yourself........is the spring just coiling tighter and tighter......why...Ignored
Considered safe havens now USD and Yen and more and more people thinking, he is USD so safe, driving them more to the last one the YEN causing the development you describe.
As a mater of fact the Yen is not as safe as most think, so a turn will come and see your 80.50 level as a level achievable very fast if safe-haven search becomes less relevant
