The Yen has been moving in a somewhat flat band defined between (just above 78.6%) 109.50 and (just below 23.6%) 110.40.
The pair has been avoiding closing below 109.10
If there are no major movers in this week, and there aren't except a significant drop in Japan Balance of Trade (IF that makes any impact at all), the USDJPY pair may continue to travel this band - although not for long. It would help to keep an eye on Bollinger breakouts.
A hawkish USD outlook would cause the USDJPY to break 110.40 and make a move towards 111.60.
