Defining CBDC and the Role of Blockchain in CBDCs

One of the first factors about central bank digital currency blockchain solutions is the definition of CBDCs. Central bank digital currency or CBDC provides digital forms of central bank money to provide unique advantages for central banks in retail and wholesale perspectives. Some of the notable functionalities of CBDCs include improved infrastructure for interbank settlements or better financial inclusion for individual customers.

CBDC basically works as a legal tender and also enjoys the backing of a central bank. Interestingly, CBDC represents a claim against the concerned central bank rather than a Payment Service Provider or a commercial bank. Generally, you have to maintain a CBDC on a digital ledger that could be either blockchain-based or not.

The digital ledger should support the speed of payments between banks, individuals, and institutions with the assurance of better security. A recent study by the Bank for International Settlements (BIS) presented favorable prospects for considering CBDC blockchain solutions. The findings of the study clearly indicate that over 70% of institutions are presently engaged in active research and development of proofs of concept for central bank digital currencies.

Another notable highlight that you can find in CBDCs refers to the control of central banks over them. The concerned central bank issuing CBDCs takes full control over the supply of CBDCs and determining the requirement for supply. 

Central Bank Digital Currency Use Cases

Now, it is important to reflect on the use cases of CBDCs to find out the feasibility of central bank digital currency blockchain solutions. The use cases of CBDCs are largely focused on retail or wholesale payments. You can assume retail CBDC as the digital variant of cash. On the other hand, wholesale CBDC points out towards a completely new infrastructure to facilitate interbank settlements.

The primary objectives of central banks in different use cases of CBDCs also play an important role in understanding CBDC blockchain solutions. Regardless of the use case, central banks want to achieve faster payments with lower costs and overheads through CBDCs. The retail CBDC is a suitable alternative for transactions between individuals and businesses as well as other individuals. It would be just like making transactions in digital banknotes.

The overall volume for retail CBDC transactions is generally more than 100,000,000 every day. On the other hand, wholesale CBDC is suitable for ensuring efficient interbank settlements. Interbank settlements generally refer to the transactions between selected banks and other entities having accounts in the concerned central bank. The overall volume of wholesale CBDC transactions is generally less than 100,000 on a daily basis.

Estimates suggest that the overall cost of clearing and settling securities across central banks in G7 countries crosses $50 billion annually. The most prominent reason for such high costs for clearing and settlement of securities for central banks refers to the requirement of resources for transferring assets and reconciliation of accounts.

In addition, the modern cross-border payment systems allow the transfer of assets alongside crucial transaction data across various correspondent banks. As a result, individuals, as well as institutions, are liable to experience higher vulnerability to settlement and operational risks. This is where CBDC blockchain solutions serve a promising answer because blockchain-based CBDCs can address the inefficiencies and vulnerabilities in existing central banking infrastructure.

Blockchain can ensure the simpler development of a secure payments system. At the same time, it can also serve the functionalities of a large-scale asset register and decentralized clearinghouse. Now, let us reflect on the advantages that you can explore with the two common types of CBDCs.
