"We are concerned by the yen's recent sharp falls in the foreign exchange market recently," Japan's top government spokesperson Matsuno said, reiterating comments from a number of top policymakers in recent months. He did not comment on currency interventions.
At a regular news conference, Matsuno also said Japan would keep monitoring the impact of inflation trends and monetary policy changes in the United States on the Japanese and global economy.
Matsuno was answering a reporter's question about the yen's decline on Thursday morning to 138 yen per U.S. dollar levels for the first time since September 1998, after U.S. annual consumer prices posted the largest increase in more than four decades, raising fears the Federal Reserve may hike interest rates even more aggressively than previously expected.
