The prospect of China’s central bank digital currency (CBDC) supporting cross-border payments has sparked widespread interest, especially after former People’s Bank of China Governor Zhou Xiaochuan shared his vision at the 2020 Shanghai Finance Forum. His insights offer a compelling look into how digital currencies could revolutionize global financial transactions—particularly in retail and international commerce.
Zhou envisioned a future where digital currency transactions occur seamlessly across borders, with real-time foreign exchange conversion and immediate compliance verification—all completed within the split second of a retail payment. This transformation, he emphasized, is made possible by dramatic advances in communication infrastructure, data processing speed, and information accessibility.
The Current State of China’s Digital Currency Pilot
Currently, China's digital currency pilot program operates under the "4+1" framework: Shenzhen, Suzhou, Xiong’an New Area, Chengdu, and the Beijing Winter Olympics venues. These trials are internal and closed-loop, focusing primarily on domestic use cases such as public transportation, retail shopping, and government services. Cross-border functionality has not yet been integrated into these early stages.
However, Shanghai’s recently released 14th Five-Year Plan proposal signals a strategic shift. The city aims to actively pursue pilot applications for digital currency, accelerate the development of its fintech hub, and build a globally connected digital financial infrastructure—all while enhancing capabilities for financial risk prevention.

This raises an important question: Could Shanghai become the testing ground for China’s first large-scale cross-border CBDC application? Zhou Xiaochuan’s remarks suggest that the technological foundation is forming—and the implications could be transformative.
Rethinking the Moment of Payment
To understand the significance of real-time cross-border digital payments, we must examine what actually happens during a transaction.
In traditional retail payments, multiple steps occur behind the scenes:
- Consumers check prices and, in cross-border cases, convert them using prevailing exchange rates.
- For cash transactions, users must prepare foreign currency in advance—exposing them to exchange rate volatility.
- Account-based payments require authentication, authorization (especially for credit cards), and encryption to prevent fraud.
- Merchants must record sales tax or VAT upon receipt and verify the legitimacy of funds.
- Financial institutions later reconcile transactions, often dealing with delays and settlement risks.
Many of these processes are pushed either before or after the actual payment due to limitations in real-time data access and processing power. For example, travelers exchange currency ahead of time without knowing future rate fluctuations. Businesses batch-process card payments hours or even days later.
Zhou argues that today’s advanced computing and communication systems allow us to redistribute this workload—performing more tasks during the transaction itself. With sufficient capacity, the “payment moment” can evolve from a simple transfer into an intelligent, self-contained financial event.
How Digital Currency Transforms Cross-Border Transactions
Imagine a traveler in Tokyo using a digital yuan wallet to buy lunch. At the point of sale:
- The system instantly retrieves the current CNY/JPY exchange rate.
- It converts the exact amount needed—no over-exchange, no leftover foreign cash.
- A smart contract verifies KYC rules, anti-money laundering (AML) conditions, and tax reporting requirements—all in real time.
- Funds settle immediately between central banks or commercial banks via distributed ledger technology (DLT).
This model offers several advantages:
- Reduced FX risk: Only the required amount is converted per transaction.
- Greater efficiency: No need for pre-loading wallets or manual reconciliation.
- Enhanced security: Encrypted data transmission and automated compliance checks reduce fraud.
- Scalability: Especially beneficial for high-frequency, low-value retail payments in Asia and emerging markets.
Zhou highlighted that blockchain and distributed ledger systems are one viable technical path forward—not necessarily as replacements for existing banking structures, but as enhancements within a two-tiered system where central banks issue digital currency and commercial banks distribute it.
Toward a Modernized Global Payment System
One of the most profound aspects of Zhou’s vision is its balance between innovation and compatibility. Rather than disrupting current financial frameworks, this approach seeks to augment them.
By anchoring digital currency in existing account-based systems and leveraging the dual-layer banking model (central bank + commercial banks), the transition becomes smoother. It preserves institutional trust while enabling new levels of automation and interoperability.
Moreover, real-time settlement across borders could significantly reduce reliance on correspondent banking networks—a decades-old system plagued by delays, high fees, and opacity. Instead, countries could establish direct digital links, paving the way for a more inclusive and efficient global financial ecosystem.

Frequently Asked Questions
Q: Is China’s digital currency already usable abroad?
A: Not yet. While pilot programs are expanding domestically, cross-border use remains experimental and limited to select bilateral cooperation projects.
Q: Will digital yuan replace physical cash completely?
A: No. The goal is coexistence. Digital currency complements physical cash, offering convenience without eliminating choice—especially important for older populations or rural areas.
Q: Can individuals hold digital yuan directly with the central bank?
A: No. China uses a two-tier system: the PBOC issues digital currency to commercial banks, which then distribute it to users through wallets and apps.
Q: Does this mean SWIFT could become obsolete?
A: Not immediately. While future CBDC networks may reduce dependence on SWIFT for certain transactions, full displacement would require broad international adoption and regulatory alignment.
Q: How does privacy work with digital yuan?
A: Transactions are traceable by authorities to prevent illegal activity, but small payments offer a degree of anonymity similar to cash—balancing oversight with user privacy.
Q: What role does blockchain play in China’s CBDC?
A: Unlike cryptocurrencies like Bitcoin, the digital yuan does not rely fully on public blockchain. Instead, it uses centralized DLT for select functions like audit trails and interbank settlement.

Final Thoughts
While many questions remain about the long-term trajectory of global money, Zhou Xiaochuan’s vision underscores a critical truth: the future of finance lies not in replacing old systems overnight, but in intelligently upgrading them.
With robust infrastructure, smart contracts, and real-time data processing, digital currencies have the potential to make cross-border payments faster, cheaper, and more secure—especially for everyday consumers and small businesses.
As Shanghai and other financial hubs push forward with fintech innovation, the world watches closely. The next chapter in monetary evolution may very well begin not with a revolution—but with a seamless tap of a smartphone.
