The two main types of CBCDs are wholesale CBDCs and retail CBDCs. The former primarily focuses on the country’s financial institutions, and the latter concentrates on individuals and businesses for day-to-day transactions.

#1 – Wholesale CBDCs

A wholesale CBDC is a type of CBDC for financial institutions. Wholesale CBDCs are used to settle interbank transfers and associated wholesale transactions. One of the instances when they are utilized in the interbank system, is making a cross-border payment using central bank digital currencies. Furthermore, central bank reserves and wholesale CBDCs both function similarly.

#2 – Retail CBDCs

A retail CBDC is a form of digital money that is distributed to the people directly by a central bank. In today’s digital economy, when the use of cash is gradually reducing, a retail CBDC, if available to everyone, may undoubtedly be an advancement in the digital economy. The supply of CBDC would entirely depend on the monetary policy of the central bank in a country.


Let us look at the central bank digital currency example to understand the concept better:

Project Bakong, the National Bank of Cambodia’s blockchain-based nationwide payment system, launched in October 2020, is one of the world’s first CBDCs. Bakong’s smartphone app is useful for making store payments and money transfers. Bakong registration does not require a bank account unless the user has a Cambodian mobile phone number.

Users can send money to others by scanning QR codes or entering the recipient’s phone number. In addition, Bakong app transactions can be done in Cambodian riel or US dollars. In the financial system, interoperability of CBDCs among various stakeholders not only improves end-user experience but also assists in bridging the gap between banked and unbanked populations.

Benefits And Drawbacks

CBDCs are becoming increasingly popular among international financial institutions due to the development of blockchain technology and cryptocurrencies. However, various CBDC pros and cons depend on how they are implemented in different countries.

Let’s look into some of the drawbacks and benefits of the central bank digital currency:


  • CBDC promotes financial inclusion by developing and contributing to an inexpensive, accessible, and secure payment system.
  • Its usage can enhance cross-border transactions by reducing the time of transactions by eliminating the intermediaries who add credit and settlement risks.
  • Individuals and financial services will benefit from the shift from hard cash to digital currencies as it will trade off the overhead cost associated with managing the money.
  • Promote real-time payments.
  • Reduces the dependence on intermediaries like banks.
  • Reduces complexity by simplifying the transaction process.


  • CBDC infrastructure management will add costs to the existing financial ecosystem because it must be resilient and always available.
  • It will bring transaction traceability, making it difficult for customers and businesses to do transactions anonymously.
  • Cyberattacks are a concern following the adoption of CBDCs, threatening the viability of the CBDC projects and raising security concerns.

CBDC vs Cryptocurrency

CBDCs and cryptocurrencies are examples of digital currencies, but they share significant differences. Some of the differences are the following:

  • CBDC may not use distributed and decentralized public ledgers like blockchain for its implementation, unlike cryptocurrencies making use of blockchain as its underlying technology.
  • CBDCs are centralized and controlled by central banks of corresponding nations, while cryptocurrencies are unregulated and decentralized. Therefore, even the issuing authority can track and control the flow of CBDC.
  • The design of CBDC points to its stability, resilience, and low volatile features hence a safer option compared to highly volatile cryptocurrencies.
