Today the USDJPY touched a high of 152.75 around GMT 23:30 (on February 5), then turned downward, reaching a low of 151.81 around GMT 01:30. Finance Minister Katsunobu Kato's comments and Bank of Japan board member Naoki Tamura's hawkish stance are strengthening expectations for a Bank of Japan rate hike.
Looking at the 1-hour chart of the USDJPY (as of GMT 03:30 on February 6), the downward bandwalk continues, and it appears poised to test the critical level of 150. The downward trend appears likely to continue.
