Gate 163 is breached! The Japanese yen plummets to its lowest level in forty years, intervention warnings have become "The wolf is coming"?

According to the Zhitong Finance and Economics app, the Japanese yen against the US dollar exchange rate has fallen below the 163 level for the first time since 1986, and the downward trend is continuing to expand. The market's test of Japan's willingness to intervene is escalating. Due to the tension in the US-Iran conflict pushing up oil prices again, the US dollar strengthened along with US bond yields. The yen fell 0.5% to 163.24 against the US dollar overnight, hitting a 40-year low.
