摘要
通过理论分析得出,当商业银行遭受流动性冲击时,其资本充足率下降,且当预期的存款流出比率小于预期的偿还借款比率时,准备金制度能够覆盖未来的存款流出;当商业银行面临流动性冲击时,无论是向中央银行借款,还是在银行间市场借款,商业银行都是在借款压力大时对流动性的需求至少不低于压力较小时的情景。此外,在假设商业银行资产收益率大于基准利率的基础上,相对于存款市场的流动性,分别讨论了银行间市场和货币政策整体流动性偏紧、银行间市场和货币政策整体流动性偏松、银行间市场流动性偏松和货币政策流动性偏紧以及银行间市场流动性偏紧和货币政策流动性偏松四种情景下,流动性覆盖率对商业银行借贷行为的影响。
This paper proves that under liquidity shock after theoretical analysis, the capital ratio of commercial banks thins and if the expected outflow of deposit is lower than expected payback, the reserves can cover the future outflow; the moment when commercial banks demand liquidity most is the time when financial markets are experiencing the most liquidity shortage. Besides, assuming the asset return rate is higher than the benchmark rate, this paper respectively discussed four scenarios all relatively to deposit market, under which how liquidity coverage ratio affects commercial banks' borrowing behavior, including tightening monetary policy and inter-bank market liquidity condition, loosening monetary policy and inter-bank market liquidity condition, tightening monetary policy and inter-bank market liquidity condition and loosening monetary policy and tightening inter-bank market liquidity condition.
