Japanese Finance Minister Taro Aso extended his verbal campaign of expressing concern about his nation’s exchange rate after the yen jumped to an 18-month high.

For at least the second time since the U.S. Treasury Department cited Japan on a currency watch list last week, Aso said his government is monitoring speculative tradesBloomberg Terminal in the yen and will respond if needed. Japan hasn’t intervened in the foreign-exchange market since 2011, instead sticking to verbal jawboning in a climate where monetary policy has played a bigger role in determining the yen’s value.
