Today’s particular economic circumstances provide a second reason for establishing a National Investment Bank. In slump or even semi-slump conditions, a higher-than-normal proportion of private savings are held in cash or its nearest equivalent (short-term treasury bills).
今天特殊的经济环境为成立国家投资银行提供了第二个理由。在萧条或近乎萧条的环境下，比平常时期更高比例的私人存款亿现金或现金等价物（短期国债）持有。国家投资银行可以通过发行基础设施开发债券利用这些“闲置存款”。
