Central banks, including the BIS, delve into shared perspectives on the design of central bank digital currency systems, focusing on privacy concerns.

The world of finance is abuzz with discussions surrounding Central Bank Digital Currencies (CBDCs), and a recent wave of papers published by the Bank for International Settlements (BIS) and seven central banks has added fuel to the fire.

The papers delve into various aspects of retail CBDCs, including privacy, security, interoperability, and legal issues. They also explore potential risks associated with retail CBDCs, such as financial stability and cybersecurity concerns.

At the heart of the debate is the question of whether to adopt a centralized or decentralized model for CBDC systems. One option, known as a two-tier CBDC system, could employ a hub-and-spoke model, where updates are under the control of the central bank but ownership of the data is distributed. Alternatively, a peer-to-peer CBDC design could be implemented, which involves sharing the authority for updates.

Countries exploring these models include China and Russia, which are actively developing digital currency infrastructure, often favoring peer-to-peer designs to enable direct transactions without intermediaries. Some European and Asian central banks are also investigating these models, but no comprehensive public list is available.

The papers highlight the need for further research and experimentation to fully understand the implications of retail CBDCs and to develop effective regulatory frameworks. They also stress the importance of maintaining public trust in the CBDC system and ensuring its compatibility with existing financial infrastructure.

Moreover, the papers emphasize the need for international coordination and collaboration in the development and implementation of retail CBDCs. The BIS and the seven central banks involved in the research—the Bank of Canada, Bank of England, Bank of Japan, European Central Bank, Board of Governors of the Federal Reserve System, Sveriges Riksbank, and Swiss National Bank—recognize the global nature of the issue and the necessity of working together to navigate the complexities of this new financial landscape.

One potential benefit of retail CBDCs is the potential improvement of cross-border payments and financial inclusion. The papers suggest that by streamlining these processes, CBDCs could help to bridge the gap for unbanked populations and facilitate international transactions more efficiently.

As the debate continues, one thing is clear: the future of money may well be digital, and central banks are at the forefront of this transformation. The papers published by the BIS and the seven central banks serve as a crucial stepping stone in the ongoing journey towards understanding and implementing retail CBDCs.
