Even then rates may be not far off the lower bound.

即使到那时，利率可能也离下限不远了。

When it comes to hard numbers, official statistics provide a lower bound to what is happening.

当谈到硬性数字时，官方统计数据给出了当前情况的一个下限值。

The usual explanation for the “zero lower bound” is that depositors can avoid negative rates by switching to cash.

通常对于零利率下限的解释是存款方可以通过改用现金避免利率变负。
