Historically, it has taken countries many years of difficult fiscal-policy efforts to regain a triple-A status. And, while no one can be certain about where the limits lie, there are both theoretical and operational bounds to how many government bonds can (and should) be placed on the balance sheet of a modern, well-functioning central bank.
历史表明，重新获得AAA地位需要为此付出多年的艰辛财政政策努力。不管从理论上还是操作上，运转正常的现代央行资产负债表上可以（以及应该）出现多少国债是存在界限的。尽管没人可以这一界限在哪里。
