The Bank made clear that the range of fluctuations in long-term interest rates, or 10-year JGB yields, would be between around plus and minus 0.25 percent from the target level, which is set at "around zero percent."
The aim is to flexibly conduct yield curve control at normal times while striking an appropriate balance between maintaining the functioning of the JGB market and controlling interest rates. On this basis, in order to secure the effects of monetary easing, the Bank introduced "fixed-rate purchase operations for consecutive days" as a measure to firmly stop a significant rise in interest rates.
