Introduction
The rapid development of electronic payments has given rise to "cashless societies," fostering new cross-border payment scenarios characterized by small amounts and high frequency. Within this landscape, digital currencies have emerged with a two-tiered structure:
- Non-sovereign digital currencies: Including Bitcoin, Ethereum, decentralized stablecoins, and private institutional digital currencies.
- Central Bank Digital Currencies (CBDCs): Sovereign-backed digital currencies.
As global central banks increasingly focus on CBDC development, the digital currency system is evolving toward sovereign dominance. CBDCs offer direct account systems that enable "transaction-settlement synchronization," reducing traditional electronic payment costs and enhancing efficiency—particularly in cross-border payments.
The Digital Currency Landscape: Transforming Global Payment Systems
1. The Rise of Cashless Payments
Mobile internet advancements have propelled electronic and contactless payment methods, significantly reducing cash usage. Key observations:
- In China, mobile payments accounted for 66% of transactions by volume (2019 data).
Despite this, cash demand persists due to:
- Anonymity: Protects privacy in an era of data vulnerability.
- Resilience: Functions in infrastructure-deficient or extreme scenarios.
2. Evolution of Cross-Border Payments
Cross-border payments face unique challenges:
- New Scenarios: E-commerce, tourism, and education drive demand for small, frequent transactions.
Electronic Payment Hurdles:
- Requires interoperability across jurisdictions.
- Must navigate regulatory disparities (e.g., anti-money laundering rules).
Digital Currency Developments: From Bitcoin to CBDCs
1. Bitcoin and Non-Sovereign Cryptocurrencies
Bitcoin introduced decentralized peer-to-peer transactions via blockchain but faces criticism:
- Energy-intensive mining: Environmental concerns.
- Price volatility: Undermines its role as stable currency.
- Illicit Use: Anonymity facilitates illegal activities.
Alternatives like stablecoins (e.g., Tether) and private digital currencies (e.g., Diem) have emerged but remain tightly regulated.
2. CBDCs and Digital Yuan
Global CBDC Progress:
- Over 80% of central banks are researching CBDCs (BIS 2020).
China leads with its Digital Currency Electronic Payment (DCEP) system:
- Piloted in Shenzhen, Beijing Olympics, etc.
- Features "transaction-settlement synchronization" and broad application scenarios.
Digital Yuan’s Definition:
- A legal tender equivalent to physical RMB.
- Combats financial exclusion via "bank account loose coupling."
Impacts and Governance: Financial Ecosystems and Global Coordination
1. CBDCs and Payment Efficiency
- Domestic Payments: Unified central accounts reduce intermediary costs.
- Cross-Border Payments: Blockchain enhances security and lowers costs for high-frequency transactions.

2. CBDCs and Credit Markets
- Credit Fundamentals Unchanged: Lending still relies on micro-level credit assessments.
- Enhanced Data Processing: Lowers征信 costs but cannot eliminate asymmetric information.
3. International CBDC Coordination
Challenges:
- Technical interoperability (e.g., multi-CBDC platforms like m-CBDC Bridge).
- Regulatory harmonization (e.g., anonymity vs. anti-fraud measures).
Opportunities:
- Collaborative standard-setting among central banks.
- Strengthening the Digital Yuan’s global influence.
FAQs
Q1: How does CBDC differ from Bitcoin?
A: CBDCs are sovereign-backed and centralized, whereas Bitcoin is decentralized and lacks government信用.
Q2: Will CBDCs replace cash?
A: No. CBDCs coexist with cash to ensure financial inclusion and resilience.
Q3: How does Digital Yuan protect privacy?
A: It uses "controllable anonymity"—transaction details are visible only to central banks for regulation.
Q4: What’s the global timeline for CBDC adoption?
A: BIS predicts 20% of central banks may launch CBDCs within 3 years, but widespread use will take longer.
Conclusion
The shift toward sovereign digital currencies marks a pivotal transformation in global finance. CBDCs promise efficiency gains but require robust governance frameworks. International collaboration will be key to harnessing their full potential while mitigating risks.
