The Yen experienced upheaval in late 2017. Foreign industrial orders for cars and durable goods affect the volatility
heavily during times of trade. Now is no different, When you have a stronger currency then it implies that stocks will be at more of a bargain. As stock prices gauge the power of a currency. The increasing separation between Topix prices correlation to the value of Yen. I see these upcoming meetings smoothing out the exchange rate long term. As there won't be any negative correlation between Japanese stocks and the value of the Yen. And instead will proceed to the usual industrial orders months later.
