USD/JPY Long. Buy Stop. The US dollar strengthens against the yen. The Japanese have only begun to feel serious pressure from most currencies, and of course the US dollar will not differ. The combination of factors helped the USD / JPY currency pair regain positive traction on Thursday. The decline in the USD after the FOMC will stop the recovery in US bond yields. The risky mood in the markets undermined the safe harbor of JPY and provided additional support for the US dollar.
