On Friday, the yen fell sharply against the dollar, trading at 148.31, following the Bank of Japan's decision to keep interest rates in negative territory. This move indicates that the bank is not in a hurry to wind down its large-scale stimulus program.
The USDJPY market is bullish still. A close over 148.88 will spark additional buying for a run beyond the last 149.71 (October 2022 high). A close under 147.58 signals a topping turnover.
