TOKYO (REUTERS) - Japanese Finance Minister Taro Aso said on Monday (May 9) that Tokyo is ready to intervene in the currency market if yen moves are volatile enough to hurt the country's trade and economy.

Mr Aso also said he did not think the United States considered Japan's currency policy to be inappropriate.

"For Japan, excessive volatility in yen moves that affect Japan's trade, economic and fiscal policies - be it yen rises or yen falls - is undesirable. If such moves occur, Japan is ready to intervene in the market," Mr Aso told parliament.
