Japan Warns Against 'Excessive' Yen Moves, Hints at Possible Intervention

Japan's Finance Minister said excessive currency market moves are undesirable and require responses. He told this to G20 finance ministers.

The yen has been weak, near 150 per dollar, due to rising US yields. Many see 150 as Japan's intervention trigger point.

The yen is down over 12% against the dollar this year due to interest rate differentials with the US.

A senior ministry official said the remarks aimed to confirm no change in currency policy stance.

Japan will act if there are excessive yen moves, the official also said.
