The Bank of Japan announced on the 28th that it will implement a measure called "limit operation" to buy unlimited government bonds at a specified yield in order to curb the rise in long-term interest rates.
As part of its monetary easing policy, the Bank of Japan plans to adjust the yield of 10-year government bonds to a fluctuation range of "plus or minus 0.25%".
In the bond market, there has been a movement to sell Japanese government bonds from the view that the pace of interest rate hikes in the United States will accelerate recently, and long-term interest rates are approaching this upper limit.
The Bank of Japan implemented this measure on the 14th of last month for the first time in about 3 years and 7 months, and this is the second time it has entered this year.
