Traders are preparing to welcome the Japanese authorities' intervention in the market and boost the yen, as demand for options with large fluctuations in the yen reached the highest level since the last time Japanese officials intervened in the foreign exchange market in 2022. The yen has fallen 10% since January, and if it continues to rapidly accelerate its decline, the Japanese authorities may intervene. Japan's chief foreign exchange officer, Masato Kanda, said in February that an increase in the yen exchange rate against the US dollar by 10 per month was considered a sharp fluctuation. The US will release the US inflation index favored by the Federal Reserve tonight. Next week's US Federal Reserve meeting and employment report may trigger a sharp drop in yen.
