According to China Securities Network, Wang Xin, director of the Research Bureau of the People's Bank of China, said on the 8th at the launching ceremony of the Digital Finance Open Research Program and the first academic seminar that the direct issuance of digital currency by the central bank will help improve the effectiveness of monetary policy. Promote the central bank's digital currency research and development. Wang Xin said that the digitization of the central bank's currency will help optimize the central bank's monetary payment function and increase the central bank's monetary status and monetary policy effectiveness. The central bank's digital currency (CBDC) can become an interest-bearing asset that satisfies the holder's reserve demand for safe assets and can also become the lower limit of bank deposit interest rates. The CBDC can also be a new monetary policy tool. First, the central bank can adjust the central bank's digital currency interest rate to affect the bank deposit and loan interest rate; the second is to help break the zero interest rate lower limit. In addition, Wang Xin believes that the next step is to explore digital finance to better support the development of the real economy. At present, digital finance business and product homogenization are serious. We should develop diversified and comprehensive financial services to meet the multi-level and diversified financial needs of the real economy. It is necessary to study how digital inclusive finance can be done in detail; how to promote cooperation between small and medium-sized financial institutions and big banks and technology giants in the field of financial technology.
