Design considerations for CBDCs
Central banks around the globe are exploring variations in CBDC design while weighing factors such as access, privacy, and distribution method. There are two common design formats for CBDCs: token-based and account-based. Each approach has a different technical infrastructure, as well as varying levels of access and privacy.
Token-based CBDCs use a digital token, and access and claims require users to have knowledge of the token (public-private key pair). This approach typically offers a high degree of anonymity; however, central banks can choose to implement identity requirements to use the network. Token transfers rely on the sender’s ability to verify the validity of the payment object and therefore require a form of distributed ledger technology for verifying the chain of ownership in each token and validating payment transactions. This also means higher end-user risk of losing a key or token held in a noncustodial wallet.
In a token-based approach, commercial banks would need to be the first line of defense for compliance with know your customer (KYC) and anti-money laundering/combating the financing of terrorism (AML/CFT) regulations. This method can provide universal access to CBDCs but also makes law enforcement more challenging compared with other designs.
Account-based CBDC access and claims are linked to a bank account tied to the identity of the account holder. This method is challenging for universal access because it still requires a banking relationship. To transfer funds, banks would process each payment by debiting the sender’s CBDC account and crediting the beneficiary’s CBDC account. Transactions need to be verified using user identities, and therefore, robust identity management systems are required to maintain a unique identifier per individual across payment systems.
In an account-based approach, compliance with KYC and AML/CFT regulation is the responsibility of the central bank. Verification of transfers in an account-based system depends on establishing appropriate safeguards against identity theft, fraud, and unauthorized transfers from valid accounts.
There are many design considerations, including distribution, access, and privacy, that need to be carefully considered to determine the right CBDC implementation. Reviewing lessons learned from existing CBDC and crypto approaches, intended benefits, and trade-offs can help a central bank determine the best approach.
Current global landscape of CBDCs
CBDCs aren’t just a theoretical concept; there are live CBDCs and many proofs of concept globally, as depicted in figure 1. Key highlights include:
- More than 60 central banks are exploring CBDCs at varying levels of maturity.
- Fourteen percent of central banks are moving forward to development and pilot arrangements.
- Three retail CBDC projects are live (Bahamas Sand Dollar, Bakong Cambodia, and Eastern Caribbean DCash).
Though countries like China, Sweden, Canada, and the United Kingdom have led research and pilot projects in the past few years, the actual execution of CBDC pilots is being led by smaller nations. In late 2020, the Central Bank of the Bahamas launched the Sand Dollar, a digital currency backed by that nation’s central bank. The Sand Dollar has facilitated easier monetary transactions across an otherwise vast archipelago. It’s also meant to improve ease of transaction, service delivery costs, and financial inclusion. The Bank started experimenting with CBDC in 2019.

Impact of CBDCs on commercial banks
Commercial banks are focused heavily on customer-facing operations, secure transactions, and regulatory reporting and are given CBDC design decisions, essential partners in successfully rolling out a CBDC. CBDCs introduce an electronic form of central bank money, adding significant complexity for commercial banks, and may imply a drastic change across the organization to keep up with the need to innovate compatible products.
As central banks embark on the digital currency journey with CBDCs, it could lead to a paradigm shift in the way domestic and global economies operate. While there’s a lot yet to be determined, the design of a CBDC will have implications for the entire financial ecosystem.
Depending on CBDC design, commercial banks will need to plan for changes in the following areas:
Next steps
The introduction of CBDCs is a disruptor for the financial ecosystem, promoting payment efficiency and representing an additional alternative to the current money model from an operational and technological point of view. Central banks are moving rapidly toward implementation, and therefore, commercial banks should use this time to explore the digital currency landscape and reimagine it for emerging services, opportunity, and value creation.

An introduction to CBDCs
A CBDC is an electronic form of central bank money with potential wide use by households and businesses to store value and make payments. It’s central bank digital money in the national unit (e.g., the US dollar) representing legal tender with the liability of the central bank, similar to physical currency in circulation. This makes CBDCs more secure and less volatile than other digital currencies. The following table presents an overview of the purpose of and common misconceptions about CBDCs.
Central bank digital currency is . . .
- Traditional money, but in digital form;
- Issued and governed by a country’s central bank;
- Influenced in terms of supply and value by a country’s monetary policies, trade surpluses, and central bank; and
- Based on a digital ledger, and may or may not leverage blockchain or distributed ledger technology.
Central bank digital currency is not . . .
- Cryptocurrency (like Bitcoin) governed by distributed autonomous communities instead of a centralized body;
- Value-dependent and determined entirely by the market; or
- Equivalent to electronic cash (e.g., balance in a digital wallet or a prepaid card) with claim against an intermediary such as a commercial bank.
CBDCs are rapidly evolving, and different central banks can take different approaches in implementation. There are a number of design decisions that lack broad consensus, including the following:
- Ability of CBDCs to completely replace notes and coins
- Degree of anonymity or privacy
- Access and availability
- Interest-bearing ability
Overall, CBDCs would offer both a new form of central bank money and a paradigm change in payments infrastructure. That’s why it becomes important to understand the benefits of CBDCs and their impacts on the wider payments landscape.
