Understanding Central Bank Digital Currencies in the Cryptocurrency Landscape

As cryptocurrencies have brought to light the drawbacks of conventional payment systems, central banks worldwide have begun to explore the notion of issuing their own digital currencies. This article delves into how central bank digital currencies (CBDCs) contrast with cryptocurrencies, their potential advantages and setbacks, as well as the controversy surrounding them.

Definition of a Central Bank Digital Currency

A Central Bank Digital Currency (CBDC) is a digital form of fiat currency, managed and issued by a central bank, and underpinned by blockchain technology. As a digital version of a nation's currency powered by blockchain, CBDCs are automatically recognized as legal tender and can be utilized for transactions. The fundamental premise behind CBDCs is to present a digital payment system endorsed by the government that addresses payment inefficiencies within a nation.

Comparison of CBDC with Cryptocurrency

Although inspired by cryptocurrencies, CBDCs differ significantly from them. The main characteristic of cryptocurrencies is their decentralized nature. Cryptocurrencies like Bitcoin$42,260 -0.64% are permissionless, borderless, and resistant to censorship. Transactions occur on public blockchains and are peer-to-peer, and there are no restrictions on how users spend their digital money.

For CBDCs, the central bank maintains control over the digital currency and supervises transactions, potentially allowing it to freeze funds, blacklist digital wallet addresses, or directly encourage individuals to spend their money, if programmable. As most CBDCs are in the hypothetical stages, their actual operationality and the level of control by central banks remain to be seen.

Types of CBDCs

CBDCs can be divided into two main types: wholesale and retail, with the classification based on the intended users. Wholesale CBDCs are aimed at financial institutions for inter-bank transactions. On the other hand, retail CBDCs are designed for the public for regular transactions. Retail CBDCs are expected to supplement traditional bank accounts and cash, but their impact on traditional financial systems is yet to be determined, as they are still in their concept and implementation phase.

Potential Benefits and Risks of CBDCs

CBDCs could potentially transform the financial landscape. However, it's too early to definitively state whether the overall change will be beneficial or detrimental for society. Below are some potential pros and cons of CBDCs.

Pros

• Elimination of Third-Party Risk: The system's stability relies on the central bank, unlike in traditional finance, where commercial banks act as counterparties.
• Cost Reduction: Dealing directly with the public, central banks bypass the current expensive banking infrastructure, potentially reducing transaction costs.
• Financial Inclusivity: CBDCs might offer a financial structure that facilitates access to financial services.

Cons

• Total Absence of Privacy: CBDC transactions would require a significant amount of personal data. The issuing central banks would be responsible for fraud monitoring and ensuring the legality of transactions, giving the government direct access to financial data.
• Government Control of Consumer Behavior: CBDCs could become a tool for the government to encourage practices in line with its policies, such as programming the CBDC to be used for buying certain goods and services.
• Centralization Risk: With CBDCs, central banks could potentially hold complete control over the digital currency, creating a single point of failure that hackers could exploit, which could have devastating effects on the economy.

Why CBDCs Are Deemed Controversial?

One significant concern with conventional finance is the control third parties exert over transactions. CBDCs would further consolidate this control, giving the government direct access to every individual's financial information. Furthermore, if a CBDC is programmable, it could allow the government to directly influence citizens' behaviors. For instance, it could prevent citizens from buying items like alcohol or cigarettes if the government wished to discourage such consumption. The potential for misuse of such access and control is clear. In a world where there is growing concern about privacy and government surveillance, CBDCs could further exacerbate these issues.
