在这种情况下，央行通过增加超额准备金，实际上等于将商业银行的负债货币化，从而增加货币流通量。

In this case the central bank - by increasing excess reserves - would DE facto monetize commercial bank liabilities and thus increase the outstanding stock of money.

而联邦储备银行则自行决定自身的负债，方法则非常简单：通过购买和出售资产，反过来这亦会等量的增加和减少商业银行的准备金。

The Federal reserve itself determines its own liabilities very simply: by buying or selling assets, which in turn increases or decreases bank reserves by the same amount.
