Japan's top foreign exchange official Jun Mimura said on Monday that the yen depreciated sharply against the US dollar after the Bank of Japan's monetary policy meeting last week, and he was “concerned” about this exchange rate trend. He told reporters: “The recent exchange rate fluctuations are characterized by being one-sided and drastic, and I am deeply concerned about this. We will respond appropriately to excessive fluctuations.” On Friday, the dollar rose to 157.67 against the yen, a four-week high. Previously, the Bank of Japan raised interest rates to the highest level in 30 years, but did not clearly state whether it will continue to raise interest rates in the future.
