Greenback slumps against the euro as Iraq advance slows

The yen fell in earlier trading against the dollar after Finance Minister Masajuro Shiokawa signaled Japan may sell its currency, boosting earnings for exporters, who close their books for the financial year on Monday. Japan's currency is up more than 10 percent in the past year.

It weakened to ¥129.16 per euro from ¥128.19, the most in a month, and has fallen 10 percent against the euro in 12 months.
