According to Xinhua News Agency, the Japanese government and the Central Bank jointly intervened in the yen. In the New York foreign exchange market, the value of the yen against the dollar reached a new high of 1 dollar to 75 yen on the 19th, prompting the Japanese government and central bank to seek joint currency intervention. On the morning of the 19th, Eastern Time in the USA, the yen-to-dollar exchange rate hit 1 dollar to 75.95 yen, refreshing the record of 1 dollar to 76.25 yen set five months ago, reaching a new high not seen since 66 years after the end of World War II. That night in Tokyo, Wu Yan, an official from Japan's Ministry of Finance's Department of International Affairs, told Dow Jones News in an interview that the Japanese government would take appropriate intervention measures when necessary. This statement made investors cautious, once curbing the upward trend of the yen, but by the end of the day, the city was still at around 1 dollar to 76.5 yen. According to a report in the "Japanese Economic News" on the 20th, the Japanese government and the Bank of Japan began discussing intervention measures, including selling yen to buy dollars in the foreign exchange market. An unnamed official from the Ministry of Finance told a reporter from the "Yomiuri Shimbun" late on the 19th that if speculative moves further push up the yen, Japan is also prepared to intervene even in overseas markets. On the 4th of this month, the Japanese government implemented its largest unilateral intervention so far, and the Bank of Japan announced the expansion of existing loose monetary policies, causing the yen to drop to the range of 1 U.S. dollar to 79-80 yen, but the effect did not last long.
