USD/JPY went up another figure on Monday, another Japanese holiday. But given the current dynamics, we unless we see another robust rally in USD/JPY, the only way we would see another intervention is the BoJ really want to beat down USD/JPY. Right now, short term speculators will not be very comfortable holding long positions and should keep a lid on the pair.
USD/JPY is trading 0.7% higher at 153.99.
