Introduction
The COVID-19 pandemic accelerated digital transformation worldwide, including the explosive growth of cryptocurrencies. In response, central banks globally are evaluating whether to issue their own Central Bank Digital Currencies (CBDCs)—virtual equivalents of traditional fiat money.
Countries like The Bahamas (with its Sand Dollar), Sweden, China, and the U.S. are at various stages of exploration. CBDCs could redefine central banking and payment systems, offering benefits like lower cross-border transaction costs, faster settlements, and broader financial inclusion. However, their design requires careful consideration of technical, economic, and social implications.
Below, we outline five pivotal decisions central banks must address when developing CBDCs.
1. Single-Tier vs. Two-Tier Systems
Single-Tier Approach
- Direct Competition: Central banks could offer CBDC accounts to consumers, bypassing commercial banks.
- Challenges: Central banks may lack infrastructure for customer support or innovative financial services.
Two-Tier Approach
- Collaboration: Central banks issue CBDCs, while private entities (e.g., banks, fintechs) distribute and innovate atop the digital currency.
- Advantages: Leverages private-sector expertise and fosters competition, improving user experience.

2. Direct Issuance vs. Synthetic CBDCs
Direct Issuance
- Centralized Control: Central banks manage the entire CBDC lifecycle.
- Best For: Institutions with robust payment infrastructures.
Synthetic CBDCs
- Public-Private Partnerships: Private companies issue stablecoins backed by central bank reserves.
- Pros: Reduces development burdens for central banks with limited resources.
- Cons: Less oversight over design and operations.
3. Account-Based vs. Token-Based Models
| Feature | Account-Based CBDC | Token-Based CBDC |
|---|---|---|
| Similarity | Digital wallets (like banking) | Physical cash-like anonymity |
| Innovation Potential | Limited | Offline payments, privacy |
| Risks | Centralized security | Higher fraud/theft risk |
4. Privacy vs. Regulatory Compliance
- Challenge: Balancing user anonymity with anti-money laundering (AML) requirements.
- Solution: Most CBDCs will mirror electronic payments’ privacy standards.
Example: Mastercard advocates for CBDCs adhering to strict consumer data protection laws.

5. Domestic vs. Cross-Border Focus
- Domestic Priority: Initial CBDCs will likely optimize for local use cases.
- Cross-Border Potential: Linking CBDCs internationally could streamline payments but requires unprecedented cooperation (e.g., shared technical standards, trust).
FAQs
Q1: What’s the difference between CBDCs and cryptocurrencies like Bitcoin?
A: CBDCs are state-backed and centralized, whereas cryptocurrencies are decentralized and often volatile.
Q2: Will CBDCs replace cash?
A: Unlikely soon—cash remains vital for privacy and accessibility in many regions.
Q3: How do CBDCs improve financial inclusion?
A: By providing unbanked populations with low-cost digital payment tools.
Q4: What risks do CBDCs pose to traditional banks?
A: If poorly designed, they could disintermediate banks, reducing deposits and lending capacity.
Q5: Which countries lead in CBDC development?
A: The Bahamas (Sand Dollar), China (e-CNY), and the EU (digital euro pilot).
Conclusion
Designing CBDCs involves trade-offs tailored to each economy’s needs. Key considerations include:
- Public-private collaboration (two-tier systems).
- Infrastructure flexibility (synthetic options for resource-constrained banks).
- User experience (account vs. token-based).
- Privacy-compliance balance.
- Scalability for future cross-border use.
The right framework will foster innovation while safeguarding stability—a milestone in the evolution of money.
