TOKYO, Oct 15 (Reuters) - Japanese Finance Minister Yoshihiko Noda said on Friday Japan will continue to take decisive steps on currencies if necessary to curb excessive moves in the foreign exchange market regardless of meetings of Group of Seven or G20 nations.
"I'll make a decision when necessary regardless of the G7 or G20," Noda told reporters after a cabinet meeting, signalling Japan's readiness to step into the currency market at any time.
Economic imbalances, the falling dollar and pressure for a rise in emerging market currencies are set to dominate discussions at a meeting in South Korea of G20 financial leaders from Oct. 22.
Noda stressed the need for countries to work together to strengthen the global currency order, adding that it would be difficult for nations to cope with the current situation individually.
"Before saying this or that about other countries' currency policies, we must do what we should do. It is important to understand each country's policy efforts first," Noda said.
Noda said Thursday's decline in the dollar, which hit a 15-year low against the yen, was a move not only against the yen but against a broad range of currencies, reflecting the U.S. economy and prospects for further monetary easing. (Reporting by Tetsushi Kajimoto; Editing by Edmund Klamann)
