在美联储资产负债表的负债表一栏里有两个主要组成部分：商业银行持有的活期存款，也即它们的准备金；和联邦储备券，即由美联储发行的现金。
On the liability side, there are also two major figures: Demand deposits held by the commercial Banks, which constitute the reserves of those Banks; and Federal reserve Notes, cash emitted by the Fed.
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.
此外，为进一步提升市场对其币值的信心，SDR的发行也可从人为计算币值向有以实际资产支持的方式转变，可以考虑吸收各国现有的储备货币以作为其发行准备。
The allocation of the SDR can be shifted from a purely calculation-based system to one backed by real assets , such as a reserve pool, to further boost market confidence in its value.
