Credit Suisse discusses USD/JPY technical outlook and sees a scope for a tactical top formation on a daily close below 108.47/24. 

"Below key 55-day average and price support at 108.47/24 would mark a top USDJPY remains capped by its falling 13- and 200-day averages as well as key price and retracement resistance at 109.21/23, and the immediate spotlight remains on key flagged support, starting at the 55-day average at 108.47 and stretching down to the 108.28/24 recent lows. A close below 108.24 would suggest a more significant top has been established to mark a more meaningful turn lower with support seen next at the 107.88 November low, with the 38.2% retracement of the entire rally from August at 107.72. Whilst we would look for this to hold at first, a break can see support next at 107.10/03. Above 109.00 can ease the immediate pressure off 108.47/24, with a break above 109.21/23 still needed to suggest the worst of the sell-off is over, clearing the way for a move back to 109.39, then a retest of the recent high and downtrend from late 2019 at 109.70/80," CS adds.
