QE是为了治理deflation 那难道不应该是让利率上升吗 所以是contract

问题如下：

Quantitative easing, the purchase of government or private securities by the central banks from individuals and/or institutions, is an example of which monetary policy stance?

选项：

Neutral.

Expansionary.

Contractionary.

解释：

B is correct.

Quantitative easing is an example of an expansionary monetary policy stance. It attempts to spur aggregate demand by drastically increasing the money supply.
