As the yen strengthened on U.S.-Japan coordination, the won-dollar exchange rate also tumbled nearly 20 won in one go, falling into the 1,440 range.

On the 26th in the Seoul foreign exchange market, the won-dollar rate opened at 1,446.1 won per dollar, down 19.7 won from the previous session. Since President Lee Jae Myung stated at his New Year press conference on the 21st that “the exchange rate will fall to around 1,400 won in a month or two,” it has declined for four consecutive trading days.

Amid expectations that U.S. and Japanese authorities will intervene in the foreign exchange market, the yen has shown strong gains, and the won, which tends to move in tandem, has also strengthened. The dollar-yen exchange rate, which had been nearing 160 yen, has fallen to around 155 yen.
