The Japanese yen posted broad gains across the board in yesterday's trading despite initially opening weaker. Investors continued to adjust their positions to the Fed's cautious plans for hiking interest rates. However, Boston Federal Reserve president Eric Rosengren warned yesterday that the markets were getting too complacent and noted that rate hikes might not be "gradual." Following Federal Reserve chairwoman Janet Yellen’s comments last Tuesday, the markets are currently pricing in a probability of a 26% probability for a rate hike in June and a 66% probability for December according to CME's Fed funds futures. USDJPY settled yesterday at 111.31. USDJPY remains vulnerable to a lot of event risks this week with Wednesday seeing the release of the March FOMC’s meeting minutes which will be followed by a speech by Janet Yellen on Thursday alongside Japan’s trade balance data.
