Japanese Finance Minister Sadakazu Tanigaki said on Thursday that Japan will continue to intervene in foreign exchange markets if it saw volatility and speculative moves. "We believe that intervention will still be necessary to hold down any irregular moves in foreign exchange markets," he said in response to questions in parliament, adding that he did not think Japan's intervention so far had been ineffective. Japan has spent about 35 trillion yen ($320 billion) over the past 15 months to hold the yen down.|||
