"Koichi Saanae's trading" triggers the yen to fall to 155, Wall Street warns: Japan's intervention "nuclear button" has not been activated yet.

According to the financial news app Smart Finance, recent research reports from Wall Street financial giants Goldman Sachs and Bank of America show that the immediate risk of intervention in the Japanese yen exchange rate is not great. They emphasize that even if the yen exchange rate accelerates depreciation to the closely watched level of 155 yen to the dollar under the "Takashimaya trade" craze, the usual conditions for triggering foreign exchange interventions have not yet been met.
