The working paper recently released by the central bank focuses on the issue of excessively high deposit reserve ratio. ANBOUND research team believes that the attention on the excessively high deposit reserve ratio of relative researches and studies shows that the central bank has already paid attention to the economic influence caused by this issue, and the adjustment on it will be an unavoidable trend. Under increasing pressure of a downward economy, the "micro stimulation" in monetary policies of the fourth quarter might be enhanced, and it might be the major instrument of the central bank to adjust economy through lowering down the required deposit-reserve ratio.
