Introduction
In July 2023, the Bank for International Settlements (BIS) reported that 93% of central banks worldwide are actively engaged in Central Bank Digital Currency (CBDC) research, with over half advancing to pilot stages. This surge reflects CBDC’s growing role as a secure, neutral, and final settlement medium for digital economies.

1. CBDC vs. Fast Payment Systems: Key Comparisons
What Is CBDC?
- Definition: A digital currency issued by central banks, denominated in national accounting units.
Types:
- Retail CBDC: For everyday transactions (households/businesses).
- Wholesale CBDC: For interbank settlements (akin to reserves).
How Does It Differ from Traditional Systems?
| Feature | Retail CBDC | Fast Payment Systems (FPS) |
|------------------|--------------------------------------|-------------------------------------|
| Issuer | Central Bank | Commercial Banks |
| Settlement | Real-time, direct on central bank’s ledger | Batch-processed, netted periodically |
| Risk | No credit risk (direct central bank liability) | Credit risk during settlement delay |
Key Advantage: CBDC eliminates intermediary risks, offering instant finality in transactions.
2. CBDC vs. Other Forms of Money
CBDC vs. Cash
- Cash: Physical, decentralized, anonymous.
- CBDC: Digital, traceable, programmable.
CBDC vs. Cryptocurrencies/Stablecoins
- Stablecoins: Privately issued, asset-pegged (e.g., USDT).
- CBDC: Sovereign-backed, legal tender status.

3. Why Are Central Banks Issuing CBDC?
Key Drivers:
- Cryptocurrency Instability: Post-2022 crypto crashes (e.g., TerraUSD, FTX) highlighted risks of unregulated digital assets.
- Financial Inclusion: Expands access for unbanked populations.
- Cross-Border Efficiency: Wholesale CBDC enhances international payments (e.g., 24/7 settlements).
Example: BIS’s Project mBridge explores multi-CBDC platforms for seamless跨境 transactions.
4. User Experience: How Retail CBDC Works
For Consumers:
- Wallet Setup: Similar to mobile payment apps (e.g., Alipay).
- Transactions: Instant, low-cost, with offline capabilities.
- Interoperability: Exchangeable with cash/bank deposits.
Note: In markets like China, CBDC may integrate seamlessly with existing digital wallets.
5. Impact on Financial Systems
Challenges & Opportunities:
- Bank Disintermediation: CBDC could reduce deposits but incentivizes banks to innovate.
- Competition: Opens payment markets to non-bank providers (lower fees, more innovation).
- Stability: Safeguards against "digital bank runs" via controlled CBDC inflows.
6. CBDC and the International Monetary System
Three Critical Effects:
- Cross-Border Payments: Wholesale CBDCs reduce代理 banking friction.
- Currency Substitution: Account-based designs mitigate foreign CBDC adoption risks.
- Reserve Status: CBDC alone won’t elevate a currency to reserve status—market depth and trust remain pivotal.
Global Collaboration: G20 and BIS initiatives ensure interoperable CBDC frameworks.
FAQs
Q1: Is CBDC the same as Bitcoin?
A: No. CBDC is centralized, sovereign-backed, and designed for stability—unlike volatile, decentralized cryptocurrencies.
Q2: Will CBDC replace cash?
A: Unlikely. CBDC complements cash, offering a digital alternative for modern economies.
Q3: How does CBDC protect privacy?
A: Designs vary; some prioritize traceability (anti-money laundering), others offer pseudonymity (token-based).
Q4: Can CBDC pay interest?
A: Possible but uncommon. Most designs focus on payment utility, not储蓄.
Conclusion
CBDCs represent a technological leap for central banks, combining security and efficiency. While resembling fast payment systems, their unique央行货币特性 (neutrality, finality) position them as critical infrastructure. Global cooperation ensures CBDCs enhance—not disrupt—financial systems.
