The global financial landscape is undergoing a profound transformation driven by rapid technological innovation and shifting geopolitical dynamics. At the heart of this evolution lies central bank digital currency (CBDC)—a digital form of sovereign money issued by national monetary authorities. As a cornerstone of next-generation financial infrastructure, CBDC is poised to redefine payment systems, enhance monetary policy effectiveness, and strengthen national financial sovereignty. This article explores the legal status, strategic functions, and regulatory challenges of CBDC, particularly within the context of China’s "New Infrastructure" development strategy.
Understanding Central Bank Digital Currency (CBDC)
Central Bank Digital Currency (CBDC) refers to a digital representation of a country's fiat currency, issued and regulated by its central bank. Unlike decentralized cryptocurrencies such as Bitcoin, CBDC is backed by national sovereign credit, ensuring stability, legal tender status, and full regulatory oversight.
In China, the People’s Bank of China (PBoC) has been at the forefront of CBDC research since 2014 through its Digital Currency Research Institute. The resulting digital yuan (e-CNY) exemplifies how a state-backed digital currency can integrate with modern technologies like blockchain, 5G networks, and big data analytics to create a secure, efficient, and traceable monetary system.

Legal Status of CBDC
1. Classification as Base Money (M0)
CBDC is legally categorized as part of the monetary base (M0)—the most liquid form of money supply, including physical cash and reserves held by commercial banks at the central bank. Unlike broader measures such as M1 or M2, which include deposits, CBDC issued by the PBoC remains under direct state control.
This classification ensures:
- Full backing by central bank assets
- Direct liability on the central bank’s balance sheet
- No credit risk for users
By replacing physical cash in circulation, CBDC streamlines the monetary structure while maintaining parity: 1 digital yuan = 1 paper yuan.
2. Sovereign Credit Backing
One of the defining features of CBDC is its state-guaranteed value. Unlike private cryptocurrencies that rely on algorithmic scarcity or market speculation, CBDC derives its legitimacy from national sovereignty.
This sovereign backing enables:
- Stable purchasing power
- Universal acceptance as legal tender
- Protection against hyperinflation and volatility
In contrast, decentralized digital assets like Bitcoin lack centralized issuance control, making them unsuitable as mainstream mediums of exchange or stores of value in regulated economies.
3. Advantages Over Traditional and Private Digital Currencies
| Feature | CBDC | Physical Cash | Private Cryptocurrencies |
|---|---|---|---|
| Issuance Authority | Central Bank | Central Bank | Decentralized Network |
| Legal Tender Status | Yes | Yes | No |
| Traceability | High | Low | Variable (often anonymous) |
| Transaction Cost | Low | Medium-High | Medium |
| Monetary Policy Integration | Full | Limited | None |
CBDC outperforms both physical cash and private digital currencies in efficiency, security, and macroeconomic integration. It supports real-time transaction monitoring, reduces counterfeiting risks, and enhances financial inclusion.
Strategic Role in New Infrastructure Development
"New Infrastructure" refers to next-generation technological frameworks—including 5G, AI, IoT, and blockchain—that support long-term economic growth. Within this ecosystem, CBDC serves as a critical enabling channel for financial modernization.
1. Enhancing Monetary Policy Precision
With CBDC, central banks gain unprecedented visibility into economic activity. Every transaction leaves a digital footprint, enabling:
- Real-time analysis of spending patterns
- Accurate measurement of inflationary pressures
- Targeted stimulus distribution via programmable "smart money"
For example, during economic downturns, the PBoC could use conditional triggering mechanisms—smart contracts that release funds only when specific criteria are met (e.g., small business payroll expenses). This prevents misallocation of relief funds and improves policy efficacy.

2. Ensuring Long-Term Currency Stability
Global reliance on dominant reserve currencies like the US dollar has exposed systemic vulnerabilities. Dollar-centric systems enable extraterritorial sanctions and financial exclusion through platforms like SWIFT and CHIPS.
CBDC offers an alternative:
- Enables direct peer-to-peer cross-border payments
- Reduces dependency on Western-dominated financial rails
- Strengthens RMB internationalization without destabilizing capital flows
By anchoring digital yuan transactions in sovereign trust rather than speculative demand, China aims to build a more resilient and equitable global monetary architecture.
3. Strengthening Financial System Security
Physical cash incurs high production and logistics costs. In contrast, CBDC:
- Eliminates printing and transportation expenses
- Reduces losses from theft or damage
- Extends financial access to remote populations via mobile wallets
Moreover, because each unit of CBDC is digitally identifiable, illicit activities such as money laundering or terrorist financing become significantly harder to conceal.
4. Modernizing Financial Governance
CBDC facilitates transformative applications across sectors:
A. Smart Credit Systems
Leveraging blockchain and big data, banks can automate loan approvals based on real-time income verification and spending behavior—reducing default risks and improving credit accessibility.
B. Automated Insurance Claims
Smart contracts can trigger instant payouts when predefined conditions occur (e.g., flight delays or auto accidents), cutting administrative costs and enhancing customer experience.
C. Dynamic Price Monitoring
Real-time transaction data allows authorities to detect price distortions early, supporting timely interventions in supply chains or essential goods markets.
Risks and Challenges of CBDC Implementation
Despite its benefits, CBDC introduces new complexities requiring careful management.
1. Increased Central Bank Risk Exposure
As CBDC adoption grows, commercial banks may see deposit outflows as individuals shift holdings directly to central bank accounts. This "disintermediation" effect could:
- Reduce banks’ lending capacity
- Increase pressure on interest rates
- Amplify systemic risk during crises
To mitigate this, a two-tier distribution model—where the PBoC issues CBDC to commercial banks, which then distribute it to the public—is being adopted to preserve existing financial structures.
2. Ambiguity in Rights and Obligations
A fully traceable digital currency raises critical questions about:
- Data privacy protections
- Government surveillance limits
- Individual financial autonomy
Without clear legal frameworks, there’s a risk of overreach—turning citizens into permanently monitored economic actors.
3. Lagging Legal Adaptation to Technological Change
Current laws struggle to address emerging issues like:
- Enforceability of smart contracts
- Liability for algorithmic errors
- Jurisdictional conflicts in cross-border transactions
There is an urgent need for legal engineering—the deliberate design of laws compatible with digital infrastructure—to ensure accountability and fairness in automated systems.
Regulatory Frameworks for Sustainable CBDC Development
To harness CBDC’s potential while minimizing risks, a comprehensive regulatory strategy is essential.
1. Establishing Unified Technical Standards
China should prioritize:
- Interoperability between digital wallets and payment platforms
- Cybersecurity protocols for transaction integrity
- Common data formats for cross-institutional reporting
Standardization ensures seamless integration across financial services and prevents vendor lock-in.
2. Building a Multi-Layered Supervision System
A robust regulatory framework must include:
- Real-time monitoring tools for detecting anomalous transactions
- Regulatory sandboxes for testing innovations under controlled conditions
- Cross-border cooperation mechanisms to combat illicit finance
These layers enable agile responses to evolving threats without stifling innovation.
3. Strengthening Oversight of Non-CBDC Cryptocurrencies
While CBDC promotes stability, unregulated private cryptocurrencies pose significant risks:
- Market manipulation
- Fraudulent initial coin offerings (ICOs)
- Use in illegal transactions
Regulators must:
- Prohibit financial institutions from offering crypto-related services
- Enforce strict KYC/AML requirements on exchanges
- Coordinate internationally to close jurisdictional loopholes
Japan’s Fund Settlement Act provides a model for legally recognizing virtual assets while imposing clear compliance obligations.
4. Integrating Law and Engineering
The future of finance lies at the intersection of code and law. To bridge this gap:
- Train hybrid professionals skilled in both law and computer science
- Embed legal rules directly into software protocols ("law as code")
- Develop audit trails for algorithmic decision-making
Only through interdisciplinary collaboration can we build systems that are both technically sound and ethically accountable.
