Central Bank Digital Currencies (CBDCs) are rapidly emerging as a transformative force in global finance, particularly in the realm of cross-border payments. As traditional systems face mounting criticism for inefficiency, high costs, and geopolitical vulnerabilities, central banks worldwide are turning to blockchain-powered digital currencies to build faster, cheaper, and more resilient financial infrastructure. This report explores the evolution of CBDCs in international payment systems, highlights key global initiatives, and examines China’s strategic push into digital yuan-based cross-border transactions.
The Case for CBDCs in Cross-Border Payments
Growing Demand and Inefficiencies in Traditional Systems
Global cross-border payment volumes continue to rise, driven by expanding e-commerce, remittances, and international trade. According to McKinsey, cross-border flows are projected to grow steadily, especially in consumer-to-business (C2B) and business-to-consumer (B2C) segments. In 2020 alone, China's Cross-border Interbank Payment System (CIPS) processed 22.05 billion transactions worth 45.27 trillion yuan—a year-on-year increase of 17.02% in volume and 33.44% in value.
Despite this growth, legacy systems suffer from critical shortcomings:
- High fees: Average transaction costs remain above 5%, far exceeding the Financial Stability Board’s (FSB) target of under 1% for retail payments by 2027.
- Slow settlement times: Traditional wire transfers can take 3–5 business days due to multiple intermediaries.
- Limited transparency: Lack of real-time tracking increases counterparty risk.
- Geopolitical exposure: Reliance on Western-controlled networks like SWIFT exposes nations to potential financial sanctions.

Technological Advantages of CBDCs
CBDCs leverage distributed ledger technology (DLT) to address these inefficiencies. Unlike conventional systems that rely on sequential verification across numerous banks, CBDCs enable parallel processing through smart contracts and decentralized validation—reducing settlement time from days to seconds.
The People's Bank of China (PBoC) has emphasized that digital RMB supports instant clearing, reduced intermediary layers, and enhanced security. By operating on permissioned blockchain networks, CBDCs maintain regulatory oversight while improving efficiency and auditability.
In October 2021, the FSB released a progress report calling for exploration of global stablecoins and CBDCs in cross-border payments before December 2022. It also set ambitious cost-reduction targets: lowering average retail payment costs globally to less than 1% and total corridor costs to below 3% by 2027.
Global CBDC Initiatives in Cross-Border Finance
Hong Kong-Thailand: Inthanon-LionRock Project
Launched in 2019, the Inthanon-LionRock project is a joint initiative between the Hong Kong Monetary Authority (HKMA) and the Bank of Thailand. Its primary goal was to develop a blockchain-based "corridor network" enabling real-time wholesale cross-border payments between Hong Kong (LionRock) and Thailand (Inthanon).
The proof-of-concept phase successfully demonstrated that:
- Cross-border fund transfers could be executed instantly.
- Intermediaries were significantly reduced.
- Settlement risks and operational costs dropped by up to 50%.
- Compliance and transparency improved via immutable transaction records.
Using R3’s Corda platform, the project connected ten participating banks and validated the technical feasibility of multi-CBDC integration. Future phases will focus on governance models, legal frameworks, scalability, and interoperability with other financial platforms.
Singapore: Project Ubin
Project Ubin, led by the Monetary Authority of Singapore (MAS), is one of the most comprehensive DLT experiments conducted by a central bank. Spanning five phases from 2016 to 2020, it explored various applications including:
- Tokenized SGD for interbank settlements
- Delivery-versus-payment (DvP) mechanisms for securities
- Cross-border payment models with Canada and the UK
- Multi-currency settlement using smart contracts
Phase 5 notably examined commercial use cases across industries such as trade finance and conditional payments. MAS made the technical specifications open-source to encourage innovation and collaboration. This inclusive approach positions Singapore as a leader in building next-generation financial infrastructure.
Canada: Project Jasper
Project Jasper, initiated by the Bank of Canada, was the first central bank-led DLT experiment involving private sector partners. Conducted in four phases between 2017 and 2019, it tested:
- High-value interbank settlements using DLT
- Securities clearing on blockchain
- Cross-border integration with Singapore’s Ubin project
While Jasper focused initially on domestic settlement, its collaboration with Ubin laid the groundwork for future multi-jurisdictional CBDC frameworks. The project confirmed that DLT could enhance speed and resilience but also highlighted challenges related to privacy, scalability, and regulatory alignment.
China’s Digital Yuan in Cross-Border Payments
Strategic Significance: Bypassing SWIFT
One of the most compelling motivations behind China’s digital currency strategy is reducing dependency on SWIFT—the dominant messaging system controlled largely by Western institutions. With only six non-Western countries holding board representation, SWIFT poses systemic risks for countries subject to geopolitical tensions.
Digital RMB offers an alternative pathway:
- Transactions settle in seconds instead of days
- Eliminates reliance on correspondent banking networks
- Reduces exposure to financial sanctions
- Enhances monetary sovereignty
By enabling direct peer-to-peer settlements across borders, digital RMB could streamline international trade and protect Chinese financial interests during periods of global instability.
Key Collaborative Projects
PBoC-HKMA Joint Testing
Since 2021, the People's Bank of China has collaborated with HKMA to test digital RMB for cross-border transactions. These trials aim to provide seamless payment services for mainland and Hong Kong residents while exploring technical requirements for broader regional adoption.

m-CBDC Bridge: A Multilateral Framework
China is a founding member of the m-CBDC Bridge, an initiative led by the BIS Innovation Hub Hong Kong Centre. Partnering with HKMA, Bank of Thailand, UAE Central Bank, and others, this project aims to create a shared platform where multiple CBDCs can transact directly.
Key features include:
- Real-time gross settlement across jurisdictions
- Smart contract-enabled synchronous delivery versus payment (DvP)
- Interoperability across different CBDC designs
- Mitigation of spillover effects on domestic monetary policy
In November 2021, the project released a use case handbook showcasing 15 potential applications—from trade finance to supply chain settlements. Over 22 financial institutions participated in early testing, processing over 2 billion yuan across four jurisdictions.
Conflux Pilot in Shanghai Free Trade Zone
In September 2021, Conflux Network announced a pilot program in Shanghai’s Free Trade Zone to test offshore RMB stablecoin transfers using its DAG-based blockchain. Leveraging high-throughput consensus (up to 6,000 TPS), Conflux aims to build an efficient channel for cross-border RMB settlements.
Backed by academic research at Shanghai Maritime University’s Tree-Graph Blockchain Research Institute, the project focuses on:
- Developing offshore RMB payment corridors
- Establishing blockchain standards for free-trade finance
- Creating shipping logistics tracking solutions
- Expanding technical ecosystems
This initiative complements national efforts by exploring private-sector-led innovations within regulated environments.
