Japan may have to take action against any disorderly, speculative-driven foreign exchange moves, the government's top currency diplomat Masato Kanda said on Tuesday, reinforcing Tokyo's readiness to intervene again to support a fragile yen.
"It is preferable for exchange rates to remain in a stable manner following fundamentals, and if the market is functioning soundly in this way, there is of course no need for the government to intervene," Kanda, Japan's vice minister of finance for international affairs, told reporters.
"However, when there are excessive fluctuations or disorderly movements due to speculation, the market is not functioning and the government may have to take appropriate action. We will continue to take the same firm approach as we have in the past."
