BBH - "There is no compelling technical evidence suggesting that the yen is about to recover. The dollar finished last week above JPY90 and the euro finished just below the JPY120 level. That said, the yen bears seem nervous."
The much anticipated BOJ meeting is here (Jan 21-Jan 22). "The market appears to have discounted additional accommodation, with another JPY10 trillion asset purchases, a doubling of the inflation goal to 2%, and possibly the elimination of the interest paid to banks on excessive reserves. The yen was sold in anticipation of these easing moves; it may be bought back on the fact."
