Digital currency represents a significant evolution in the financial landscape. Understanding its core functions, structural design, and practical implications is essential for both industry professionals and the general public. Former People's Bank of China Governor Zhou Xiaochuan recently addressed several critical questions regarding digital currency, offering valuable insights into its development and implementation.
What Defines the Core Functions of Digital Currency?
Digital currency retains the fundamental roles of traditional money. These include serving as a medium of exchange, a unit of account, and a store of value. The payment function is particularly foundational—without reliable payment capabilities, adoption for pricing or storing value becomes challenging. This emphasis on seamless transactions guides the primary development direction for digital currencies worldwide.
Enhancing payment efficiency remains a central goal. By focusing on this core utility, developers can create systems that are not only functional but also widely adoptable.
Why Emphasize Retail Payments in Development?
Retail payments directly impact everyday economic activities. Serving the real economy is a cornerstone of financial policy, and digital currency should prioritize reducing costs while improving accessibility and reliability for consumers and businesses.
Technological advancements offer substantial room for improvement in retail payment systems. Innovations can streamline processes, enhance security, and expand access. While wholesale payments also benefit from upgrades, their existing infrastructure is generally more robust, leaving greater potential for gains in the retail sector.
The Strategic Importance of a Two-Tier System
A two-tier system integrates commercial banks and payment service providers with central bank oversight. This model leverages existing financial infrastructure while introducing new digital currency capabilities.
Why Adopt This Model?
Maintaining system stability is a primary concern. The current two-tier banking system has demonstrated reliability over time. Introducing digital currency within this framework minimizes disruption and ensures compatibility with established market economies.
Promoting healthy competition is another advantage. Multiple institutions striving to enhance services drive innovation, improve efficiency, and accelerate technological adoption. This dynamic benefits consumers through better products and stronger security protocols.
Central banks can focus on broader responsibilities like macroeconomic regulation and financial stability. This includes safeguarding against illicit activities such as money laundering and terrorist financing, while also strengthening defenses against cyber threats.
Implementing the Two-Tier Approach
Successful implementation requires collaboration with secondary institutions. Encouraging competition and ensuring interoperability between systems fosters continuous improvement. Allowing space for smaller-scale innovations enables practical testing and natural selection of the most effective solutions.
Evaluating Digital Currency Stability
Stability is a critical concern for any currency. The concept of "stablecoins" emerged to address volatility, but stability assurances vary widely.
Factors Influencing Stability
Full reserve backing is a traditional method for ensuring stability. However, the details matter—where reserves are held, how they are managed, and the transparency of reporting all impact credibility.
Central bank digital currencies (CBDCs) typically offer high stability, but this isn't universal. Management quality varies globally, and historical instances of hyperinflation underscore that purchasing power preservation is the true measure of stability.
Stability exists on a spectrum rather than as a binary state. While CBDCs often rank near the top, privately issued digital currencies may exhibit lower reliability, especially if oversight is inadequate.
The Role of Regulation
Strong regulatory frameworks enhance stability. Institutions like Hong Kong's note-issuing banks operate under strict supervision, with high capital requirements and segregated business activities. This isolation prevents operational risks in unrelated sectors from affecting currency reliability.
In contrast, technology companies engaging in diverse ventures may expose their digital currencies to unrelated business risks. Comprehensive regulatory oversight helps mitigate these vulnerabilities.

Can Cross-Border Payments Bypass Exchange Rates?
Exchange rates remain unavoidable in international trade. Most nations prioritize monetary sovereignty, avoiding full "dollarization" to retain policy flexibility and crisis response capabilities.
Digital currencies don't eliminate this reality. Nations developing sovereign digital currencies will still need mechanisms to manage exchange rates between them. Differences in policy regimes and capital controls necessitate coordinated approaches to foreign exchange management.
The Future of Cross-Border Digital Currency Payments
Multiple models exist for cross-border CBDC interactions. These range from a dominant currency used across borders to a shared intermediary platform or coordinated national systems.
The most complex but likely approach involves individual national digital currencies with integrated settlement mechanisms. Exchange rates would be determined in foreign exchange markets, with real-time rates available at the point of payment.
Cross-border transactions require strict compliance controls. Anti-money laundering measures, counter-terrorism financing rules, and restrictions on prohibited activities like gambling are essential. Smart contracts can automate these checks, enabling efficient and secure transactions.
Quantity controls, such as per-transaction or annual limits, can also be programmatically enforced. Modern cloud computing and mobile technology make such features feasible to implement.

Frequently Asked Questions
What are the primary advantages of digital currency?
Digital currencies can reduce transaction costs, increase payment speed, and improve financial inclusion. They also offer programmability through smart contracts, enabling automated compliance and innovative financial products.
How does a two-tier system benefit consumers?
This system encourages competition among service providers, leading to better rates, improved user experiences, and more innovative features. It also maintains stability by leveraging existing banking infrastructure.
Are digital currencies completely risk-free?
No currency is entirely without risk. Digital currencies face challenges related to cybersecurity, regulatory changes, and technological failures. However, central bank digital currencies generally offer higher security than privately issued alternatives.
Can digital currency be used without internet access?
Some systems support offline transactions using near-field communication or other technologies. However, full functionality typically requires internet connectivity for real-time verification and settlement.
How might digital currencies affect traditional banks?
Banks may face increased competition but also gain new opportunities to offer digital services. The two-tier system ensures they remain integral to the financial ecosystem by facilitating distribution and user support.
What determines the value of a digital currency?
Value depends on factors like trust in the issuing institution, underlying reserve assets, and market demand. For sovereign digital currencies, monetary policy and economic conditions also play significant roles.
