What is a Central Bank Digital Currency (CBDC)?
A Central Bank Digital Currency (CBDC) is a digital form of a country's fiat currency, issued and regulated by the central bank. Unlike physical cash or traditional bank deposits, a CBDC exists purely in digital form and represents a direct liability of the central bank — just like the banknotes in your wallet, but digital.
Think of it as digital cash. Instead of carrying physical pound notes, you'd hold digital pounds in a digital wallet, directly backed by the Bank of England. No commercial bank sits in the middle.
Why Do Central Banks Want CBDCs?
Several factors are driving the global push toward CBDCs:
- Declining cash use — Contactless payments and digital banking have reduced physical cash usage, especially in the UK where card and mobile payments dominate.
- Financial inclusion — CBDCs could provide banking access to the estimated 1.4 billion people worldwide who remain unbanked.
- Payment efficiency — Faster, cheaper cross-border payments without multi-day settlement delays.
- Monetary policy tools — Central banks could implement policy more directly, including programmable money features.
- Private crypto competition — CBDCs offer a state-backed digital alternative to stablecoins and private cryptocurrencies.
The UK Digital Pound
The UK Digital Pound is the Bank of England's proposed CBDC. Currently in the research and consultation phase, the Digital Pound would be a retail CBDC — available to individuals and businesses for everyday transactions.
Key features of the UK Digital Pound include:
- 1:1 value with physical GBP — Always worth exactly £1
- Privacy protections — The Bank of England states it would not have access to personal data, though a "privacy threshold" for large transactions is being discussed
- Offline capability — Payments could be made without internet access, similar to cash
- No interest — Initially proposed as non-interest-bearing to avoid disrupting the banking system
- Holding limits — Likely capped at £10,000–£20,000 per person to prevent bank runs
CBDC vs Cryptocurrency: Key Differences
Despite both being "digital money," CBDCs and cryptocurrencies are fundamentally different:
| Feature | CBDC | Cryptocurrency (e.g. Bitcoin) |
|---|---|---|
| Issuer | Central bank (government) | Decentralised network |
| Supply | Controlled by central bank | Fixed / algorithmic |
| Privacy | Government-monitored | Pseudonymous |
| Volatility | Stable (pegged to fiat) | Highly volatile |
| Programmability | Potentially programmable | Smart contract based |
| Borderless | Tied to jurisdiction | Global by design |
Which Countries Have CBDCs?
As of 2025, over 130 countries are exploring CBDCs. Fully launched CBDCs include:
- Nigeria (eNaira) — Launched 2021, Africa's first CBDC
- Bahamas (Sand Dollar) — Pioneering retail CBDC launched 2020
- China (Digital Yuan / e-CNY) — The world's largest CBDC pilot, reaching 260+ million users
- Jamaica (Jam-Dex) — Launched 2022
- Eastern Caribbean (DCash) — Multi-country CBDC
The European Central Bank is developing the Digital Euro, and the Bank of England continues its Digital Pound consultation, with a potential launch in the late 2020s or early 2030s.
Will CBDCs Replace Cash?
Most central banks, including the Bank of England, state that CBDCs are designed to complement cash, not replace it. However, as cash usage declines naturally, a CBDC ensures the public continues to have access to state-backed money in a digital age.
The UK government has committed to protecting access to cash for as long as people need it, while simultaneously preparing the infrastructure for a Digital Pound.
