Still, over the longer run, there is no guarantee that any central bank will be able to hold the line in the face of adverse shocks such as continuing slow productivity growth, high debt levels, and pressure to reduce inequality through government transfers. The risk would be particularly high in the event of other major shocks – say, a general rise in global real interest rates.
然而从长远来看，没有人能保证任何中央银行将能够在面对不利冲击时保持通胀水平，例如持续的生产力增长放缓，高负债水平，以及通过政府转移支付减少不平等的压力。风险会在遭受其他重大冲击时变得特别高——例如说，全球实际利率的上升。
