QQE with Yield Curve Control, which was adopted in September 2016 after the comprehensive assessment, is in line with my argument, so I agree with this framework in principle.
Even so, the current guideline for market operations -- to set the short-term policy interest rate of minus 0.1 percent and the target level of yields on 10-year Japanese government bonds (JGBs) at around 0 percent -- could lead to holding JGB yields in negative territory up to a maturity of ten years.
