Saudi Arabia Concludes Participation in China-Backed mBridge Digital Currency Project, Signaling Strategic Realignment in Global Digital Finance

Saudi Arabia has officially withdrawn from mBridge, the ambitious China-backed multi-central bank digital currency (CBDC) project designed to facilitate direct cross-border transactions, according to a recent report by the Financial Times. The Saudi Central Bank (SAMA), which had joined mBridge as a full participant in June 2024, concluded its involvement after successfully completing a proof-of-concept (PoC) phase on May 13, 2025. SAMA confirmed that its departure was pre-planned, indicating a strategic evaluation of the project’s utility and alignment with its broader financial technology objectives. This development comes amidst a complex global landscape where nations are increasingly exploring digital currencies, balancing innovation with geopolitical considerations.

The Genesis and Evolution of Project mBridge

Project mBridge was established in 2021 as a collaborative initiative between the Bank for International Settlements (BIS) Innovation Hub and the central banks of China, Hong Kong, Thailand, and the United Arab Emirates. Its core mission was to address the persistent inefficiencies, high costs, and slow settlement times inherent in traditional cross-border payment systems. The existing correspondent banking network, reliant on multiple intermediaries and varying regulatory frameworks, often results in delays, opaque fees, and increased counterparty risk. mBridge sought to revolutionize this by creating a platform that allows participating central banks to issue and transact in their own digital currencies on a shared, distributed ledger.

Unlike systems that might rely on a single stablecoin, mBridge’s design allows for interoperability between different CBDCs, enabling direct peer-to-peer payments and foreign exchange transactions between central banks and commercial banks operating within the network. This approach aims to drastically reduce the number of intermediaries, thereby lowering transaction costs, accelerating settlement times, and enhancing transparency. The project’s development was meticulously guided by the BIS until October 2024, when it achieved its minimum viable product (MVP) stage. At this juncture, the BIS formally handed over the project’s reins to the participating central banks, signifying a transition from an exploratory research phase to a more operational and collaborative development stage. Agustín Carstens, then-General Manager of the BIS, explicitly stated that the BIS’s departure was purely technical and not politically motivated, a clarification that underscored the project’s growing geopolitical resonance.

Saudi Arabia’s Engagement and Planned Exit

Saudi Arabia’s entry into mBridge in June 2024 was seen by many as a significant endorsement of the project’s potential and a reflection of the Kingdom’s growing interest in advanced financial technologies. As one of the world’s largest oil exporters and a key player in global finance, Saudi Arabia’s participation added substantial weight and credibility to the initiative. Its central bank, SAMA, engaged fully in the proof-of-concept phase, which involved testing the technical feasibility, operational efficiency, and potential benefits of using the mBridge platform for various cross-border transactions. This phase, which culminated on May 13, 2025, would have allowed SAMA to assess the platform’s performance in real-world or simulated scenarios, evaluating aspects such as transaction speed, cost savings, security protocols, and regulatory compliance.

SAMA’s statement, as cited by the Financial Times, clarified that its decision to conclude participation was pre-planned, indicating that its involvement was always contingent on the successful completion and evaluation of the PoC phase. This suggests a strategic approach rather than an abrupt withdrawal driven by unforeseen issues. Central banks often engage in such pilot projects to gather data, understand new technologies, and inform their domestic digital currency strategies without necessarily committing to long-term operational integration. For Saudi Arabia, this exploration aligns with its broader Vision 2030 goals of economic diversification and digital transformation, where embracing cutting-edge financial technology is a key pillar. The successful completion of the PoC means SAMA has likely gained valuable insights into the practicalities and challenges of multi-CBDC platforms, which can now inform its independent development of a potential Saudi riyal CBDC or its engagement with other cross-border payment initiatives.

The Technological Underpinnings of mBridge

At its core, mBridge leverages distributed ledger technology (DLT), specifically a permissioned blockchain, to create a common platform for multiple central bank digital currencies. This "shared ledger" concept is crucial. Instead of each central bank maintaining separate ledgers and relying on a chain of intermediaries for cross-border transactions, mBridge allows them to interact directly on a single, shared infrastructure.

Key features include:

• Interoperability: The platform is designed to handle different CBDCs, meaning a transaction initiated in, say, China’s digital yuan can be settled directly in Thailand’s digital baht without needing an intermediate conversion to a traditional fiat currency like the US dollar.
• Atomic Settlement: Transactions are designed to settle almost instantly and simultaneously (atomically), reducing settlement risk and enhancing efficiency. This is a significant improvement over traditional systems where funds might be held by intermediaries for days.
• Reduced Costs: By cutting out multiple correspondent banks, mBridge aims to lower transaction fees and improve foreign exchange rates by reducing spreads.
• Enhanced Transparency: The DLT provides a transparent and immutable record of transactions, which can aid in compliance and reconciliation, though specific details of transaction visibility would be governed by participant agreements.
• Programmability: CBDCs on the platform could potentially support programmable payments, allowing for automated transactions based on pre-defined conditions, opening up new possibilities for trade finance and supply chain payments.

This technological architecture presents a compelling alternative to the existing SWIFT-based system, offering a glimpse into a potentially more efficient and resilient future for global payments.

Geopolitical Dimensions and US Scrutiny

While the BIS maintained that its role in mBridge was non-political, the project has undeniably garnered significant geopolitical attention, particularly from the United States. A 2024 report by the US-China Economic and Security Review Commission explicitly highlighted concerns that mBridge could eventually provide an alternative cross-border settlement system for countries seeking to circumvent US sanctions.

This apprehension stems from several factors:

• De-dollarization Narratives: The US dollar’s dominance in international trade and finance grants the US significant leverage, particularly through its ability to impose sanctions. Projects like mBridge are perceived by some as potential tools to reduce reliance on the dollar-centric financial system, thus eroding US financial hegemony.
• Strategic Competition: The development of digital currencies has become a new front in the broader strategic competition between major global powers. China, in particular, has been a frontrunner in CBDC development with its digital yuan (e-CNY), and mBridge is seen as an extension of its efforts to establish influence in the digital financial sphere.
• Sanctions Evasion: The ability for countries to conduct direct transactions in their local digital currencies, outside the traditional SWIFT network, could theoretically make it more challenging for the US to monitor and enforce sanctions against targeted entities or nations.
• Financial Surveillance: While mBridge aims for transparency among participants, concerns exist regarding the potential for data privacy and surveillance implications, especially given the involvement of countries with different regulatory and governance standards.

These concerns underscore the dual nature of digital currency innovation: while offering technical efficiencies, it also carries profound implications for global power dynamics and economic security. Saudi Arabia’s engagement, even if temporary, would have been viewed through this geopolitical lens by international observers.

Saudi Arabia’s Digital Ambitions and Broader Context

Saudi Arabia’s Vision 2030 framework places a strong emphasis on technological advancement and economic diversification away from its traditional reliance on oil. The Kingdom has been actively investing in various fintech initiatives, artificial intelligence, and smart city projects like NEOM. Its exploration of digital currencies, therefore, is a natural extension of these broader strategic objectives.

SAMA’s involvement in mBridge can be interpreted as part of a multi-pronged strategy:

• Research and Development: Gaining hands-on experience with cutting-edge multi-CBDC technology.
• Risk Assessment: Understanding the potential risks and benefits associated with such platforms.
• Policy Formulation: Informing the development of its own domestic CBDC strategy. SAMA has previously announced its own CBDC exploration, and insights from mBridge would be invaluable.
• International Collaboration: Positioning Saudi Arabia as a proactive player in shaping the future of global digital finance.
• Diversifying Payment Channels: While not necessarily abandoning traditional systems, exploring alternatives can enhance resilience and offer more options for international trade and investment.

The decision to conclude participation after a PoC suggests that SAMA has achieved its immediate objectives for learning and evaluation. It could indicate that the insights gained are sufficient for now, or that the Kingdom might prioritize other digital payment initiatives, either domestically or through alternative international collaborations that better align with its specific strategic priorities and risk appetite. It is not uncommon for central banks to participate in multiple pilot projects concurrently or sequentially to gather a comprehensive understanding of the evolving landscape.

China’s Continued Focus on Digital Currencies

Meanwhile, China’s central bank, the People’s Bank of China (PBOC), remains deeply committed to advancing the role of digital currencies in cross-border payments. The PBOC has been at the forefront of CBDC development globally with its e-CNY, which has seen extensive domestic trials. The mBridge project is a crucial component of China’s strategy to extend the reach and utility of digital currencies internationally.

Wang Xin, Director General of the PBOC’s Research Bureau, has consistently called for closer monitoring of stablecoins and CBDCs in cross-border payments, alongside greater international coordination. This reflects China’s desire to shape the global regulatory and operational frameworks for digital currencies, ensuring they align with its strategic interests. The PBOC’s proactive stance also includes measures to restrict the unauthorized issuance of renminbi-pegged stablecoins and tokenized real-world assets, particularly by foreign entities, demonstrating a cautious but firm approach to maintaining control over its monetary sovereignty in the digital age. This dual approach – fostering innovation while tightly regulating the digital asset space – is characteristic of China’s broader economic and technological strategy.

Implications for mBridge and Global Finance

Saudi Arabia’s planned withdrawal, while not an indictment of the project’s technical viability, carries several implications:

• Credibility and Adoption: While SAMA’s exit was planned, the optics of a major economy concluding its participation might lead some to question the project’s long-term appeal or the commitment of its participants. However, if the PoC was genuinely successful for Saudi Arabia’s objectives, it could also be seen as a validation of the project’s ability to deliver valuable insights, even if not leading to immediate full integration.
• Future Participation: The success or challenges faced by current participants, and the reasons for others like Saudi Arabia concluding their involvement, will influence future decisions by other central banks considering joining mBridge.
• Competition and Alternatives: The digital payments landscape is rapidly evolving. Saudi Arabia’s decision might reflect an assessment that other initiatives or bilateral arrangements could better serve its interests, or that its domestic CBDC development requires undivided focus. There are numerous other cross-border payment initiatives, including the BIS’s Project Dunbar and ongoing bilateral CBDC explorations.
• De-dollarization Debate: While mBridge aims to offer an alternative, Saudi Arabia’s measured approach suggests that major economies are not necessarily rushing to abandon the dollar but rather exploring resilient and efficient payment channels as part of a diversified strategy. The dollar’s entrenched position as the global reserve currency and primary invoicing currency for commodities like oil means any shift will be gradual and complex.
• Regional Dynamics: The UAE remains a full participant in mBridge, highlighting varying strategic priorities within the Gulf Cooperation Council (GCC) countries regarding digital currency adoption and international financial partnerships.

Ultimately, Saudi Arabia’s planned exit from the mBridge proof-of-concept phase underscores the complex and multi-faceted nature of digital currency development. Central banks are navigating a landscape where technological innovation, economic efficiency, and geopolitical considerations are inextricably linked. The insights gained by SAMA from its mBridge participation will undoubtedly contribute to the Kingdom’s evolving digital finance strategy, potentially shaping its approach to a domestic CBDC and its future engagement in the global digital payments arena. The mBridge project, meanwhile, continues its development, aiming to redefine the architecture of cross-border transactions in a world increasingly moving towards digital economies.
