>>821947564% is pretty good and near term means it doesn't matter if inflation continues up because you constantly roll into higher rate bonds. I don't know what country you're from so I can't say much about your government's bonds, that's why I'm focusing on USTs here.
It's dumb because it grants special status to one form of investment over another for no apparent reason. Why not give special status to share ownership, sovereign debt, etc? It's a handout to the banking industry which is distortionary. If you want to give special status to something, do it to dividends to encourage participation in the stock market. That doesn't distort any one industry and still encourages investment flow.
