A central bank digital currency (CBDC) is a digital form of government-issued money created and regulated by a nation's central bank. Unlike stablecoins issued by private companies, CBDCs represent a direct liability of the central bank, making them functionally equivalent to physical cash in digital form.
How CBDCs Work
CBDCs are issued and controlled by central banks as digital versions of national fiat currencies. They operate on technology infrastructure determined by the issuing authority, which may include distributed ledger technology or centralized databases.
Key characteristics include:
- Issued and backed by the sovereign guarantee of the central government
- Regulated directly by monetary authorities
- Designed to function alongside or replace physical cash
- May operate on permissioned networks controlled by the central bank
CBDCs can be designed for retail use by consumers or wholesale use for interbank settlements.
Types of CBDCs
- Retail CBDCs: Designed for everyday transactions by individuals and businesses, retail CBDCs function as digital cash accessible to the general public.
- Wholesale CBDCs: Used for large-value transactions between financial institutions, wholesale CBDCs aim to improve interbank settlement efficiency.
CBDCs Compared to Stablecoins
While both are digital currencies designed for stability, CBDCs and stablecoins differ fundamentally:
- CBDCs are issued by central banks; stablecoins are issued by private entities
- CBDCs carry sovereign backing; stablecoins rely on reserve assets
- CBDCs are regulated as national currency; stablecoins face varying regulatory treatment
- CBDCs provide governments monetary policy tools; stablecoins operate independently
Current Status
Over 130 countries are exploring CBDC development. China's digital yuan is among the most advanced retail CBDC pilots. The United States has taken a different approach, with recent policy favoring private stablecoins over a domestic CBDC.
Risks and Considerations
CBDCs raise important questions:
- Privacy concerns regarding government visibility into transactions
- Potential disintermediation of commercial banks
- Cybersecurity risks to centralized infrastructure
- Cross-border interoperability challenges
- Impact on existing monetary policy transmission
The design choices made by central banks will determine how these considerations are addressed.
Summary
A central bank digital currency is a digital form of sovereign money issued by a national monetary authority. While sharing some use cases with stablecoins, CBDCs differ fundamentally in their governance, backing, and regulatory status.
As central banks worldwide continue exploring digital currency issuance, CBDCs represent a government-led approach to modernizing payments infrastructure.
