At the monetary policy meeting held until the 17th, the Bank of Japan decided to maintain a large-scale monetary easing policy that would keep short-term interest rates negative and long-term interest rates at around 0%.
In addition, in the statement released earlier at the meeting that decides on monetary policy, it was stipulated that "it is necessary to pay close attention to trends in the financial and foreign exchange markets and the impact on Japan's economy and prices" as a risk factor.
This seems to be based on the rapid depreciation of the yen in the foreign exchange market against the backdrop of widening interest rate differentials between Japan and the United States.
