CBDCs have become a hot topic of conversation, with growing interest from governments worldwide, particularly as societies increasingly embrace cashless transactions and cryptocurrencies. In this comprehensive guide, we'll delve into the world of Central Bank Digital Currencies (CBDCs), examining their nature, functionality, availability, future prospects, and how they stack up against stablecoins.



Understanding CBDCs

CBDCs are digital tokens representing fiat currency and are currently under development and utilization in select countries. The acronym CBDC stands for Central Bank Digital Currency.


In the realm of finance, "fiat" denotes a currency backed by a government's authority, as opposed to assets like gold. Historically, fiat currency has taken the form of physical coins and banknotes. However, the advent of technology and digital financial transactions has prompted some governments to explore digital credit models as a complementary extension of fiat currency. Transactions within this model are recorded digitally.


While conventional currencies remain in circulation and are widely accepted, the use of physical cash is diminishing in many regions. Increasingly, people are turning to credit cards, debit cards, and e-wallets for their financial transactions. The emergence of CBDCs garnered heightened attention during the global COVID-19 pandemic, which commenced in 2020 and brought about widespread closures and restrictions.


As global populations increasingly embrace cashless payment systems and cryptocurrency adoption grows, governments are exploring opportunities to introduce digital currencies, recognizing the potential benefits they offer. Presently, only a select few countries have launched their own digital currencies.


How CBDCs Operate

CBDCs are often described as digital fiat currencies, uniquely identified to prevent counterfeiting, given that most countries use fiat as their national currencies.


In contrast to traditional digital payments, where multiple intermediaries are involved in handling money, verifying transfers, and facilitating transactions, CBDCs operate more akin to cryptocurrencies. They enable direct transactions between account holders, bypassing intermediaries.


Another similarity between CBDCs and cryptocurrencies is their reliance on a network for validation and tracking. While cryptocurrencies employ blockchains, ensuring anonymity and maintaining a digital ledger of transactions, CBDCs may be connected to a central database controlled by the issuing central bank. Each unit of CBDC is issued with a unique identification number for tracking and may be linked to the country's national currency.


CBDCs backed by fiat remain valid across various digital payment systems and can be transmitted through a range of digital platforms. To enhance accessibility, some CBDC proposals mandate that all citizens hold an account with the issuing central bank.


Motivations for CBDCs

Several driving forces underpin the development of central bank digital currencies. Sovereignty is a key factor, as it reinforces a nation's control over its currency and fosters trust in the central bank as the currency's issuer. Additionally, CBDCs aim to enhance the efficiency of financial systems.


Financial inclusion is another compelling driver, as CBDCs can expand access to financial systems for the unbanked population. Many impoverished individuals in various countries rely heavily on cash, presenting a barrier to financial inclusion. Central banks can establish open, two-tiered systems that cater to the needs of these individuals.


Furthermore, CBDCs play a role in improving fiscal and monetary policies. These digital tokens can mitigate liquidity constraints and offer citizens an easily accessible alternative to other payment methods, bolstering the nation's financial stability and economic growth.



CBDC Objectives

Central bank digital currencies (CBDCs) have a range of potential benefits, addressing the factors discussed earlier. However, governments also have broader objectives in mind. Here are the main goals governments aim to achieve with CBDCs:


  1. Enhance fiscal and monetary policies.
  2. Reduce dependence on expensive financial services like payday loans and money orders.
  3. Tackle financial inclusion challenges by providing better access to underserved populations.
  4. Improve financial system efficiency through real-time data benefits.
  5. Offer payment solutions that prioritize convenience, privacy, ease of transfer, and financial security.
  6. Lower the costs associated with cross-border transactions.
  7. Minimize the maintenance demands of more complex financial systems.
  8. Ensure stability through financial sovereignty and establish a backup for other digital payment systems in case of disruptions.


In addition to these objectives, governments need to consider strategies for CBDCs to gain popularity and maintain their usage, especially in competition with cryptocurrencies. They must address potential challenges, including lower transmission rates, and emphasize the unique advantages of CBDCs to the public.


Governments must also recognize the appeal of cryptocurrencies, which are backed by blockchains and offer user anonymity. To compete effectively, governments need to convey the value and benefits of CBDCs to the population while addressing any concerns or risks.


Despite the challenges, CBDCs offer various benefits, and governments should seek opportunities to mitigate threats and enhance domestic private payment systems for greater efficiency and suitability. This effort can also lead to improvements in international payment systems.


However, building trust may be a significant challenge for governments, particularly in regions where there is widespread distrust in the national government. Establishing trust in CBDCs will be crucial to their success.



Types of CBDCs

CBDCs come in two primary forms, each serving different purposes, and a hybrid approach is also possible. Here's an overview of these CBDC types:


  1. Retail CBDCs:

Retail CBDCs are government-backed digital currencies designed for use by businesses and consumers. Their primary goal is to eliminate the risks associated with private currency issuers going bankrupt, which could result in customers losing their funds. Retail CBDCs can take two main forms:


  • Account-based: Users need digital identification for access.
  • Token-based: This structure employs private or public keys and offers user anonymity since it relies on tokens instead of user identification.


  1. Wholesale CBDCs:

Wholesale CBDCs function similarly to how central banks hold reserves. They enable central banks to provide accounts for users to transfer funds, manage interbank transfers, set interest rates, and influence lending activity. The key distinction here is that wholesale CBDCs involve financial institutions as intermediaries between customers and central banks. In contrast, the relationship between central banks and citizens is more direct in a retail CBDC structure.



The Emergence of CBDCs and Stablecoins

CBDCs have gained momentum, with some countries already adopting them and others exploring their potential. This section provides insights into countries that have launched digital currencies or have ambitious plans for them.



In 2021, Nigeria introduced its digital currency, eNaira, becoming the first African nation to do so. The eNaira, accessible through digital wallets, facilitates contactless payments and money transfers. It employs a hybrid structure combining wholesale and retail CBDC features. This digital currency operates on the Hyperledger Fabric blockchain, designed by IBM.


The Bahamas:

The Bahamas introduced the Sand Dollar in 2020, marking the world's first nationwide CBDC implementation. It combines wholesale and retail aspects and aims to provide a secure, efficient, and near-instantaneous payment solution for its citizens. While promising, the Sand Dollar constituted a small fraction of the nation's circulated currency in 2022.



China initiated digital yuan (eCNY) trials in 2020, with plans for widespread adoption by 2022. eCNY's scalability is set to increase significantly. Unlike some other countries, China's digital currency primarily functions as a retail CBDC, issued by the central bank for retail transactions, and is not blockchain-based.



France's central bank conducted a successful CBDC test program in 2020, focusing on interbank transactions and utilizing blockchain technology. Collaborating with HSBC and IBM, France is considering expanding its CBDC to offer greater payment flexibility to citizens in the future.



Canada's central bank partnered with MIT to develop a digital version of the Canadian dollar, primarily as a contingency measure. The project's aim is to ensure a digital currency is available if required, adapting to changing trends.


South Korea:

South Korea, despite past opposition, is exploring CBDC development, intending to incorporate both wholesale and retail applications. Unlike China, South Korea envisions its digital won to be controlled by a distributed ledger, rather than a central authority. Implementation is targeted for 2023, with regulatory enforcement by 2024.



Sweden is testing the eKrona, a digital version of its krona, in response to declining cash usage. The eKrona incorporates a hybrid system, blending wholesale and retail elements. However, privacy concerns related to its token verification system need resolution before issuance.


The global landscape for CBDCs is evolving rapidly as countries adapt to changing payment trends and explore digital alternatives to traditional currencies.



CBDCs vs. Stablecoins: Key Distinctions

While CBDCs and stablecoins may seem similar at first glance, they possess notable differences:


  1. Issuer and Nature:
  • CBDCs are government-issued legal tender, regulated by central authorities, intended for use as standard currency.
  • Stablecoins are private, digital assets typically pegged to a currency, and they are not issued or controlled by governments.


  1. Technology:
  • Both are digital assets, but stablecoins commonly utilize blockchains for transactions, while CBDCs may or may not incorporate blockchain technology.


  1. Regulation:
  • CBDCs are subject to national regulations and monitored through centralized systems by government authorities.
  • Stablecoins operate within decentralized networks and lack centralized regulation, being governed by blockchain consensus mechanisms.


  1. Objectives:
  • CBDCs maintain the traditional banking system's structure, reinforcing the central authority's role.
  • Stablecoins aim to democratize global financial systems, offering alternatives to traditional currencies.


The Future of CBDCs: Rising Interest and Regulation

Following the Terra crash, discussions on regulating stablecoins have gained traction globally. Governments view it as their responsibility to protect citizens from financial crises, and they seek to safeguard their currency control.


Regulators express concerns about the absence of clear guidelines for stablecoins, signaling a growing interest in imposing restrictions on cryptocurrencies. CBDCs, too, are garnering attention as governments adapt to evolving payment and currency trends.


Countries conducting CBDC tests and the increasing number expressing intentions to develop their own central bank digital currencies underscore the seriousness with which nations are approaching this emerging financial landscape.



Conclusion: Balancing Opportunities and Challenges

If CBDCs become more prevalent, they have the potential to address accessibility issues and enhance the stability of national financial systems, provided they are well-designed and effectively implemented. However, the regulatory scrutiny aimed at stablecoins, coupled with their development, introduces complexities for investors to navigate in the evolving digital currency landscape.
