USD/JPY fell sharply to as low as 146.47 last week and there is no sign of bottoming yet. Initial bias remains on the downside this week. Sustained break of 38.2% retracement of 140.25 to 150.87 at 146.81 will argue that fall from 150.87 is reversing the whole rally from 140.25. In this case, deeper decline would be seen to 61.8% retracement at 144.30 and below. Nevertheless, strong support from 146.81, followed by break of 148.29 minor resistance resistance, will argue that fall from 150.87 is merely a correction, which has completed already.
In the bigger picture, no change in the view that price action from 151.89 (2023 high) are correction to up trend from 127.20 (2023 low). The question is whether this correction has completed at 140.25, or extending with fall from 150.87 as the third leg. Sustained break of above mentioned 146.81 fibonacci level will favor the latter case. But even so, downside should be contained by 50% retracement of 127.20 to 151.89 at 139.54
In the long term picture, as long as 125.85 resistance turned support holds (2015 high), up trend from 75.56 (2011 low) is still in favor to continue through 151.93 (2022 high) at a later stage.
