According to the Wall Street Journal reported on the 22nd, the four central banks have cooperated with the bank for International Settlements to create a model platform to support the use of a variety of central bank digital currencies for international settlement, indicating that countries have accelerated the layout of central bank digital currency R & D and application. The innovation center of the bank for International Settlements and the central banks of Australia, Malaysia, Singapore and South Africa announced on the 22nd that the above platform had been completed. These institutions said that the platform shows that financial institutions can trade directly with the digital currency issued by the central bank participating in the platform. These institutions said in a statement that the platform called project Dunbar has the potential to reduce dependence on intermediaries and reduce the cost and time of processing cross-border transactions. In the process of developing the platform, the central banks said that they solved the problem of which entities should be allowed to use the digital currency issued by the central bank for trading, and how to solve the differences in payment supervision in different countries. In fact, many countries have accelerated the layout of central bank digital currencies recently. Earlier this month, US President Joe Biden signed an executive order requiring US government agencies to assess the benefits and risks of establishing a central bank digital currency, as well as other cryptocurrency issues. According to the executive order signed by Biden, in the context of the rise of private cryptocurrency, the United States will "place the highest urgency of R & D on the potential design and deployment options of digital currency". It is reported that the US central bank's digital currency may have the potential to support efficient and low-cost transactions, especially in cross-border capital transfer and payment. This will promote the entry of digital currency into the financial system, and the transaction risk of central bank's digital currency may be lower than that of private digital assets. The head of the Financial Technology Department of the Central Bank of Qatar said that the Central Bank of Qatar is about to issue a future plan and focus on the vertical field of financial technology. He said that the Central Bank of Qatar has fully recognized the importance of Digital Banking and may issue digital banking licenses in the future. In addition, the development of digital money market has also attracted the attention of the Central Bank of Qatar, which plans to participate in the research of digital money of global central banks in the future.
