According to CoinMeta, the Japanese yen has fallen below the 160 level against the US dollar, highlighting the vulnerability of the yen's further weakening and also increasing the risk that Japanese authorities may intervene again to slow down the decline of the yen. Although there is still uncertainty regarding the specific trigger level, strategists warned on Monday that there are many factors that could prompt Japanese authorities to intervene again to prevent a significant weakening of the yen, with the recent trigger possibly being around 161, followed by the 162 to 163 range. Rinto Maruyama, a senior interest rates and foreign exchange strategist at Nomura Securities, stated that in terms of key levels, 161 is the first level that needs attention, followed by the 162.9 to 163.3 range, where authorities last intervened.
