That forecast, moreover, is based on quite optimistic assumptions of strong economic growth and low interest rates. With slower growth and more normal interest rates, the debt ratio could easily rise to more than 100% in 2021, and exceed 150% by 2030.
此外，这一估计是建立在十分乐观的经济增长和低利率假设上的。如果增长率没有那么高，名义利率没有那么低，则债务比率将在2021年突破100%，在2030年超过150%。
