The chart i have put up here is Ratio chart between US & Japan 10 year Bond price. this ratio chart has inverse correlation to $/Yen. Ratio chart which is a blue line broke down from the channel is likely to continue lower given the momentum on weekly & daily chart, which is likely to send the pair higher from here. I am also doubtful whether issue between N.K. & U.S. would actually escalate further as china is urging restraint over North Korea. Moreover the world knows about the destruction which nukes can have, but you never know as both Trump & Kim-Jong-Un are extreme minded people they can worsen the situation though.
