TOKYO (AFX-ASIA) - Bank of Japan governor Masaru Hayami said that if the dollar/yen moves in an excessive way, it will be reversed by market forces. "If the dollar/yen moves further excessively, it will be reversed by market forces," Hayami said when asked about the longer-term outlook for the currently weaker yen. He said that the yen has fallen some 20 pct from levels seen in the latter part of last year and that he does not properly understand why the US unit has proved so strong. Japan has a huge current account surplus and funds overseas, he noted. Hayami, speaking after a government meeting on the cabinet office monthly economic report, said that there had been no discussion of monetary policy at the meeting.
