Over the years, there has been a visible evolution of money, evolving from seashells to metal coins, paper money, to digital bank transfers. 

 

In recent years, Central banks around the world, including those of China, the European Union, Nigeria, and the Bahamas, have been actively developing or piloting CBDCs.

 

Think of a form of money, something that isn’t cryptocurrency, that combines reliability, state-backed security of physical cash, alongside the digital ease of your bank app! One would agree that it does represent the most significant evolution of money in centuries.

What is a Central Bank Digital Currency?

A central bank digital currency is a digital representation of a nation's fiat currency, such as the US dollar or the pound sterling, created and issued by the central bank of that country.

 

They are not backed by a precious metal, such as gold or silver, nor by any other tangible asset or commodity, but rather fixed in value by the government.

 

Similar to the physical currency, it is a direct claim on the central bank, but it operates online, and in contrast to cryptocurrencies, which are decentralized and erratic, it aims to provide stability. 

 

These differences make CBDCs stand at the middle of the traditional finance and the innovative financial technology, thereby creating a significant renovation of the monetary system.


How Do CBDCs Work?


Even though CBDCs are often associated with blockchain, the technology that powers the CBDCs can vary. The major concept behind CBDCs is having a digital ledger maintained by the central bank or authorized intermediaries.

 

The CBDCs come in two forms, which are the retail and wholesale. The retail CBDC is used by the general public and can be held in a wallet on any individual’s mobile phone to pay for goods and services, just like cash.

 

The wholesale CBDC, on the other hand, settles high-value securities transactions, such as those between banks and other financial institutions, thereby improving the financial system's efficiency.

Differences Between Physical Cash, CBDC, and Cryptocurrency

The core difference between physical cash, CBDC, and cryptocurrency lies in who is in charge, i.e, who controls it, and its underlying philosophy.

 

The table below shows a detailed breakdown of the key differences between Central Bank Digital Currencies (CBDCs), cryptocurrency, and physical cash.

Why Governments are interested in CBDC

Central Bank Digital Currencies (CBDCs) are being investigated by governments and central banks not just for technological reasons but also because they believe they can be a useful instrument in addressing a number of important issues facing the contemporary financial system.

 

Here’s a breakdown of the potential strong advantages of why there’s a global push for CBDC:

 

  • To Maintain Sovereignty and Control Over Money: This is arguably the most powerful motivator, especially as the rise of cryptocurrencies and, more importantly, stablecoins (private digital currencies pegged to government currency) threatens to erode this control. A state-backed digital currency is the government’s answer to ensuring that the official unit of account of the nation is being secured.
  • To Improve Payment Systems and Efficiency: At the moment, many existing payment systems are slow and very expensive, especially the ones for transactions across borders. CBDC could make it possible for both domestic and international transactions to happen quickly and affordably.
  • To Enhance Financial Inclusion: A huge portion of the population in many countries lacks access to basic financial services. This is something that could be tackled by CBDC, as it offers a secure means of storing and using digital currency for people without access to traditional banking.
  • To Strengthen Monetary Policy: The Central banks believe that CBDCs could give them more powerful and direct tools to manage the economy. They think it would give them new, simple ways to implement monetary policy, as they are exploring interest-bearing CBDCs as a tool, though this remains theoretical and controversial.

Major Concerns and Risks of CBDCs

Even though the benefits of the CBDCs are high, it doesn’t override the significant questions that are highly debated. While the governments and central banks highlight the potential benefits, economists, privacy advocates, and financial experts have raised serious concerns.

 

Here are the major concerns and risks associated with CBDCs:

 

  • Privacy Erosion and Mass Surveillance: Since CBDC transactions are digitally recorded on a central ledger, they create a permanent, auditable record of financial transactions.
    • Civil Liberty organizations and citizens argue that this data may be compromised or exploited by governments, allowing unprecedented surveillance.
    • Additionally, they assert that the awareness that every transaction is being watched over may have a "chilling effect" that discourages consumers from buying particular goods or services or endorsing controversial causes.
  • Financial System Disruption and Bank Runs: Economists and commercial banks believe that in times of economic stress or fear about a bank’s health, people can, in an instant, and with a few clicks, move their savings from their commercial bank into a "safe" CBDC, which is the central bank's direct liability.
    • The economists and commercial banks argue that this could trigger a digital bank run of unprecedented speed, crippling commercial banks before they could respond.
  • Cybersecurity Threats and Technical Failure: This is another major concern as a centralized, national digital currency (CBDC) could be a prime target for attacks, with a single point of failure potentially paralyzing the entire economy.
    • Software flaws, power outages, and technical issues can all cause system outages. Digital wallets containing CBDC may still be susceptible to hacking, device theft, and phishing schemes, which could result in an irrevocable loss of money.
