The dollar rose as high as 102.28 yen on the EBS trading platform, its highest since May 29. The euro rose as high as 138.83 yen, its highest since June 2009. Immediate resistance for the euro is the 139 yen level, last broken in June 2009, and then 139.26 yen, its peak set that month.
The greenback last fetched 102.02 yen, down about 0.1 percent on the day, while the euro bought 138.53 yen, also down about 0.1 percent. But so far this month, both the euro and dollar are up nearly 4 percent against the yen.
