A permanent policy of yield curve control by central banks at a time when inflation is picking up would make sense

We believe the following configuration could be seen in OECD countries in the aftermath of the COVID crisis: A gradual rise in inflation, due to population ageing, a return to regional value chains and a correction of the skewing of income distribution against employees; Central banks permanently using yield curve control, i.e. keeping nominal long-term interest rates low; This would lead to persistently negative real long-term interest rates, which makes sense to : Restore investment and therefore potential growth, which has been weakened by the recession; Gradually reduce debt ratios.
