If they raise rates to 8% to match “official” inflation then after taxes rates are still negative 4%. They would have to raise rates to 30% to have an honest 0% real rate after taxes. Or they could remove income tax on interest below inflation rate.
如果他们将利率提高到 8% 以匹配“官方”通胀，那么税后利率仍为负 4%。他们必须将利率提高到 30%，才能获得诚实的 0% 税后实际利率。或者他们可以取消对低于通货膨胀率的利息征收的所得税。
