Central Bank Digital Currencies (CBDCs) are becoming one of the most talked about topics in finance. Countries around the world are actively exploring the possibility of creating and implementing their own government-backed digital currencies based on blockchain technology or other digital solutions. CBDCs represent a new development in the financial system that could change the way money, financial services and the global economy as a whole work. In this article, we look at what CBDCs are, their potential, challenges and possible implications for the global economy.
1. What is a CBDC?
CBDC is a digital form of national currency issued by a country’s central bank. Unlike cryptocurrencies such as bitcoin or etherium, CBDCs are backed by the state and have an official legal status, making them an analogue to traditional fiat money, only in a digital format.
CBDCs can exist in two main forms:
(a) Retail CBDCs
These digital currencies are designed to be used by ordinary citizens and businesses for everyday transactions such as purchases of goods and services, fund transfers and other financial transactions. They can replace physical cash and simplify access to financial services.
(b) Wholesale CBDCs
Wholesale CBDCs are designed to be used by financial institutions such as banks and payment processors to conduct large transactions among themselves. They can improve the interbank settlement process, making it faster, cheaper and safer.
2. How do CBDCs work?
CBDCs can operate based on a variety of technologies, including blockchain, distributed ledgers or other forms of digital infrastructure. Central banks would manage the issuance, distribution and control of digital currencies, which would maintain government control over the money supply and monetary policy.
(a) Centralised model
In this model, the central bank directly manages CBDCs by issuing them into circulation and controlling transactions. This model provides a high level of control over the currency but can be less flexible and prone to technical failures.
(b) Decentralised model
In a decentralised model, CBDCs can use blockchain technology where transactions are recorded in a distributed ledger, but the central bank still retains control over the money supply and can regulate transactions. This model can provide greater flexibility and resilience to technical risks.
(c) Hybrid model
Some countries are considering a hybrid system where CBDCs can be managed by the central bank but integrated with commercial banks and other financial institutions, allowing for greater access to services and preserving existing banking infrastructure.
3. Benefits of CBDCs
The introduction of central bank digital currencies can bring many benefits to both national economies and the global financial system:
(a) Simplification of monetary transactions
CBDCs can greatly simplify the process of remittances and payments. They will provide instant transactions with minimal fees, which is especially important for international transfers, which can be slow and expensive in the traditional system.
(b) Expanding financial inclusion
The introduction of CBDC can help millions of people who do not have access to traditional banking services to access financial instruments through mobile devices. This is particularly relevant for developing countries where the proportion of people without a bank account remains high.
(c) Controlling the money supply
CBDCs allow central banks to better control the money supply and implement more effective monetary policy. This can help fight inflation, manage interest rates and ensure the stability of the national economy.
(d) Combating financial crime
Digital currencies that can be tracked and monitored by central banks will help reduce financial crimes such as money laundering and tax evasion. Transparency and digitalisation of financial transactions will make them more accountable.
(e) Reducing the costs of cash production
The production and circulation of cash involves high costs of printing, transporting and protecting it. Switching to digital currencies can significantly reduce these costs.
4. Challenges and risks of CBDC implementation
Despite the many benefits, CBDC implementation also comes with a number of challenges and risks:
(a) Technological risks
CBDCs require a robust and secure digital infrastructure. Any technical failures or cyber-attacks could lead to loss of funds or paralysis of the financial system. Central banks will have to invest in cybersecurity and data protection.
(b) Privacy threats
CBDCs may allow central banks to track every transaction, which raises concerns about user privacy. Finding a balance between transparency and data protection will be a key challenge in CBDC design and implementation.
c) Threat to commercial banks
CBDCs may reduce the demand for commercial bank services, especially if citizens start directly storing their funds in central banks’ digital accounts. This could cause an outflow of deposits from the banking system and disrupt commercial financial institutions.
(d) Regulation and international co-operation
Successful implementation of CBDC will require harmonisation of international standards and regulations. Each country will develop its own digital currency and it is important that they can co-operate effectively in the international arena, especially for cross-border payments.
5. CBDCs and the future of the global economy
CBDCs can significantly change the global economy by offering new mechanisms for international payments and influencing the monetary systems of different countries. Especially interesting is the scenario in which CBDCs will be able to compete with traditional reserve currencies such as the US dollar or the euro. Countries that have implemented CBDCs may improve their economic resilience and gain additional tools to manage their economies.
Conclusion
CBDC is a promising and innovative form of money that has the potential to radically change the global financial system. Despite technical and regulatory challenges, CBDCs promise to improve financial inclusion, simplify transactions, and make monetary policy more efficient. The introduction of central bank digital currencies will open up new opportunities for national economies and make the financial system more flexible and technologically advanced.
