The USDJPY has been pushed up (with other JPY pairs) as the market awaits the Bank of Japan decision later today. Although the central bank is not expected to ease, there has been some rumblings in the market that the potential exists for easing soon. If that is indeed communicated tonight, the USDJPY should have some room to run on the upside. The next key resistance would come at the 82.81 level.
Looking at the daily chart above, the USJPY has support at the 81.05-18 where trendline support is found.
