What are CBDCs: Exploring the Future of Money

From the barter system to banknotes, the evolution of money has always been about improving convenience and trust. Digital currencies represent the latest leap in this journey, transforming money into a purely digital form.

Unlike traditional currencies, CBDCs are designed to leverage technology for enhanced security and speed in transactions. With more than 130 countries in development on their own digital currency, they have emerged as a pivotal development in response to the digital transformation of finance.

What are CBDCs?

Central Bank Digital Currencies (CBDCs) are digital forms of a country's official currency, issued and regulated by the nation's central bank. They stand apart from other digital money, like cryptocurrencies and e-money, by being state-backed, offering higher security, and legal tender status.

CBDCs are designed with a set of core goals in mind, reflecting the interests of the central banks issuing them as well as the broader interests of the economies they serve.

Their main goals of CBDCs include:

1. Programmability: CBDCs can be designed with programmable capabilities, enabling the embedding of smart contracts and automated execution of transactions under specific conditions. This opens up possibilities for innovative financial products and services, such as automatic tax collection, real-time financial compliance, and targeted disbursement of funds for social programs.
2. Enhanced Financial Inclusion: CBDCs could provide people with access to a digital form of legal tender, especially in regions where access to traditional banking is limited or non-existent. This could help integrate a larger portion of the population into the formal economy.
3. Improved Payment Efficiency: They offer the possibility for faster and cheaper transactions, both domestically and internationally, by reducing the need for intermediaries and streamlining cross-border payments.
4. Increased Monetary Policy Effectiveness: With CBDCs, central banks could implement monetary policy more directly. For instance, they could adjust interest rates on CBDCs to influence spending and saving behaviors more effectively than with traditional monetary tools.
5. Enhanced Security and Reduced Fraud: Digital currencies controlled by central banks could have advanced security features, reducing the risk of counterfeiting and fraud. Moreover, CBDCs could improve the traceability of funds, aiding in the fight against money laundering and the financing of terrorism.
6. Stability and Control: By issuing digital currencies, central banks can maintain more control over the monetary system, especially as digital payments become more prevalent and private cryptocurrencies gain popularity. This can help ensure the stability of the national currency and financial system.

These goals vary in priority and specificity across different countries, reflecting their unique economic conditions, financial systems, and policy objectives.

The design and implementation of CBDCs are carefully tailored to address these goals while balancing the potential risks and challenges associated with digital currencies.

Why are CBDCs Gaining Attention?

CBDCs are sparking interest because they promise to overcome the inefficiencies of traditional digital payment systems. These systems, while convenient, often face issues like high transaction fees, slow processing times across borders, and limited access in underbanked regions.

CBDCs, backed by central banks, aim to provide a more inclusive, efficient, and secure financial infrastructure. This has led to a global wave of interest from central banks, exploring how CBDCs can modernize payments, enhance financial inclusion, and secure national financial sovereignty in a digital age.

It’s important to point out that CBDCs are very different from cryptocurrencies. CBDCs are centralized digital currencies issued and regulated by central banks and operate within the existing financial system and are subject to governmental policies and regulations, where cryptocurrencies operate on decentralized networks and are not controlled by any central authority, relying instead on a distributed network of nodes to validate transactions. But much like cryptocurrencies, CBDCs are touted as a revolution in finance that could bring a new level of interoperability and accessibility to global markets.

Types of CBDCs

CBDCs come in two main types: retail and wholesale. What is different about these two implementations is who will use them and the scale at which they’ll be used. Each is built and owned by the government but has a different role in the economy.

Retail CBDCs are designed for use by the general public, aiming to enhance financial inclusion, improve payment efficiency, increase the resilience of payment systems, and provide new tools for monetary and fiscal policies.

They offer several benefits, including broad accessibility through digital technologies, reduced transaction costs by minimizing intermediaries, increased security as they are central bank-backed, and potential for financial service innovation.

However, the implementation of retail CBDCs comes with challenges such as addressing privacy concerns while ensuring transaction transparency, safeguarding against cybersecurity threats, mitigating financial stability risks like potential bank runs during crises, and overcoming hurdles related to system design and adoption.

Achieving international coordination for cross-border payments adds an additional layer of complexity to the development of a CBDC for use by people.

Wholesale CBDCs, on the other hand, are digital currencies issued by central banks for exclusive use by financial institutions that hold reserve deposits with them. These are aimed at improving the efficiency and security of high-value transactions and settlements between banks and other financial entities.

Wholesale CBDCs seek to streamline payment systems, reduce settlement times, and lower transaction costs, enhancing the overall functioning of the financial system.

The primary benefits include increased transaction speed and reduced costs, thanks to the elimination of intermediaries and the use of blockchain or similar technologies. This leads to more efficient interbank settlements, improved liquidity management, and enhanced security measures against fraud and cyber threats.

Challenges such as ensuring interoperability between different systems, maintaining privacy while ensuring compliance with financial regulations, and the risk of centralizing financial power and data with the central bank need to be addressed.

CBDC Use Cases

CBDCs cater to a diverse range of applications across both retail and wholesale financial landscapes:

Retail Use Cases:

• Everyday transactions and payments, providing a digital alternative to cash that's both secure and easy to use.
• Financial inclusion initiatives, offering access to banking services for unbanked or underbanked populations, potentially revolutionizing how people engage with the financial system.

Wholesale Use Cases:

• Interbank settlements, improving the efficiency and speed of large-value transfers between financial institutions.
• Cross-border payments, simplifying and accelerating transactions across countries, which currently can be slow and costly due to intermediary processes.

Each of these applications highlight CBDCs' potential to enhance payment systems, foster financial inclusivity, streamline interbank operations, and facilitate more efficient international trade and commerce.

CBDCs also offer a range of applications across both retail and wholesale sectors, addressing various challenges in the current financial landscape:

• Peer-to-Peer Transactions: They enable direct transfers between individuals, cutting down on fees and enhancing transaction speed.
• Business-to-Business Payments: CBDCs facilitate faster and more secure transactions between companies, potentially integrating smart contracts for automated dealings.

Challenges with CBDC Development

While CBDCs offer innovative opportunities, they also raise significant challenges and concerns. Privacy is a major issue, as CBDCs could potentially allow governments to track financial transactions closely, raising questions about how to balance innovation with personal privacy.

The introduction of CBDCs might also disrupt the traditional banking system, potentially diminishing the role of commercial banks in the economy by providing an alternative, more direct form of banking with the central bank.

There are also considerable technical hurdles in developing a CBDC infrastructure, including ensuring system security, scalability, and resilience against cyber-attacks, as well as addressing issues related to interoperability with existing financial systems and technologies.

Many of these challenges were studied in a recent global collaboration led by Swift. It was the largest CBDC industry collaboration to date and involved 38 central banks, commercial banks, and market infrastructures around the globe. The working group demonstrated advancements in trade flows, tokenized securities, FX settlements, and CBDC payments—all on a network hosted by Kaleido. The study made clear that while CBDCs showed clear promise to improve financial systems, interoperability, the need to connect various emerging and traditional systems, was the key challenge to solve going forward.
