Saudi Arabia has officially withdrawn from mBridge, the ambitious cross-border digital currency project spearheaded by China and the Bank for International Settlements (BIS), a move that underscores the complex and evolving landscape of international digital finance and geopolitical influences. The departure of the Kingdom, a significant economic player and a key member of the G20, comes after it completed its participation in a proof of concept, raising questions about the project’s future trajectory and the broader strategies of nations in the nascent central bank digital currency (CBDC) space.

According to reports from the Financial Times, citing a statement from the Saudi Central Bank (SAMA), Saudi Arabia’s involvement as a full participant in mBridge commenced in June 2024. However, its active engagement concluded on May 13, 2025, upon the successful completion of a planned proof of concept phase. SAMA confirmed that its withdrawal was pre-planned, indicating a strategic evaluation rather than an abrupt halt. This controlled exit suggests that while the Kingdom explored the technical viability and potential benefits of the platform, it maintains a flexible approach to its long-term digital currency strategy.

Understanding the mBridge Initiative: A Vision for Faster, Cheaper Cross-Border Payments

The mBridge project, formally known as the "Multi-CBDC Bridge," was established in 2021 as a collaborative effort under the auspices of the BIS Innovation Hub, in partnership with the central banks of China (People’s Bank of China), Hong Kong (Hong Kong Monetary Authority), Thailand (Bank of Thailand), and the United Arab Emirates (Central Bank of the UAE). Its primary objective was to leverage distributed ledger technology (DLT) to make cross-border payments significantly faster, cheaper, and more efficient, addressing long-standing pain points in the global financial system such as high transaction costs, lengthy settlement times, and operational complexities.

Unlike some digital currency initiatives that propose a single global stablecoin, mBridge adopts a unique model. It allows participating central banks to issue and transact in their own respective digital currencies (wholesale CBDCs) on a shared DLT platform. This interoperable framework facilitates direct transactions between central banks, enabling more streamlined cross-border payments and foreign exchange transactions without the need for multiple intermediaries or correspondent banking relationships, which often add layers of cost and delay. The project’s technical architecture is designed to support real-time, atomic settlement of payments and foreign exchange transactions, thereby reducing settlement risk and improving liquidity management.

A Detailed Chronology of mBridge’s Development

The mBridge project has seen significant milestones since its inception, reflecting a steady progression from conceptualization to a tangible product.

• 2021: The project officially launched as "Project Inthanon-LionRock" (a collaboration between Thailand and Hong Kong), which later evolved into mBridge with the inclusion of China and the UAE, under the BIS Innovation Hub’s guidance. The initial focus was on exploring the feasibility of a multi-CBDC platform for wholesale cross-border payments.
• 2022: A pilot program was successfully conducted, involving real-value transactions between participating central banks and commercial banks across four jurisdictions. This pilot demonstrated the platform’s ability to facilitate instant cross-border payments and foreign exchange operations, handling over 160 cross-border payments and foreign exchange transactions totaling over $22 million.
• June 2024: Saudi Arabia, through SAMA, joined mBridge as a full participant, signaling its strong interest in exploring the forefront of digital finance innovation and potentially positioning itself as a leader in the MENA region’s digital economy. This expansion brought a significant oil-exporting nation into the fold, adding considerable weight to the project’s global aspirations.
• October 2024: The BIS announced that mBridge had reached its Minimum Viable Product (MVP) stage. At this juncture, the BIS Innovation Hub transitioned the project’s development and governance to the participating central banks themselves, marking a crucial step towards operationalization. Agustí n Carstens, then General Manager of the BIS, clarified that the BIS’s reduced direct involvement was a natural progression as the project matured, not a politically motivated withdrawal.
• May 13, 2025: SAMA concluded its participation in the mBridge proof of concept, as planned, leading to its official withdrawal.

Geopolitical Undercurrents and US Scrutiny

While the BIS has maintained that its role in mBridge is purely technical and non-political, the project has undeniably garnered significant attention and scrutiny from US policymakers, particularly within the context of intensifying geopolitical competition with China. The development of alternative cross-border payment systems, especially those not reliant on the existing dollar-dominated SWIFT system, is often viewed through a strategic lens in Washington.

A comprehensive 2024 report from the US-China Economic and Security Review Commission (USCC) explicitly highlighted mBridge as a potential concern. The report suggested that the platform could eventually provide an alternative cross-border settlement system for countries seeking to circumvent or evade US sanctions. This perspective underscores a broader worry in the US that China’s advancements in digital currencies and financial infrastructure could chip away at the dollar’s global dominance and provide tools for adversaries to bypass American financial leverage. Such concerns are rooted in the understanding that control over the global financial plumbing grants significant geopolitical power, allowing the US to enforce sanctions and influence international economic behavior.

The USCC report’s analysis points to a future where countries, particularly those with strained relations with the US or those seeking greater financial autonomy, might increasingly turn to platforms like mBridge. This could lead to a fragmentation of the global financial system, creating parallel payment rails that are less susceptible to Western oversight and influence. The potential for such a system to facilitate transactions for sanctioned entities or states is a key point of apprehension for US national security strategists.

Saudi Arabia’s Strategic Calculus: A Multifaceted Approach to Digital Finance

Saudi Arabia’s decision to withdraw, despite its initial full participation, can be interpreted through several strategic lenses, reflecting the Kingdom’s broader economic diversification efforts under Vision 2030 and its evolving position in global finance.

Firstly, SAMA’s statement that its withdrawal was "planned" and occurred after completing a "proof of concept" suggests a methodical approach. It indicates that Saudi Arabia likely used its participation to thoroughly evaluate the technology, its benefits, risks, and alignment with its own national digital transformation agenda. For a nation embarking on ambitious reforms, experimenting with cutting-edge financial technologies is crucial. The completion of a PoC might imply that SAMA gathered sufficient data to inform its future digital currency strategy, which may not necessarily involve full integration into mBridge at this stage.

Secondly, Saudi Arabia is actively pursuing its own national digital transformation initiatives, including exploring its own wholesale and retail CBDC options. It is plausible that the insights gained from mBridge will feed into its domestic CBDC development, allowing SAMA to cherry-pick the most suitable architectural elements and governance models for its specific needs. The Kingdom might prioritize developing a sovereign digital currency infrastructure that offers greater control and alignment with its national economic policies, rather than committing to a multilateral platform that might carry geopolitical baggage or design constraints not perfectly suited to its long-term vision.

Thirdly, Saudi Arabia maintains strong economic and strategic ties with both China and the West. Navigating this complex geopolitical landscape requires a delicate balancing act. While mBridge offers a pathway to potentially de-dollarize certain transactions and reduce reliance on Western-dominated financial systems, full commitment might also be seen as aligning too closely with one bloc over another. Saudi Arabia’s approach might be to explore various digital finance avenues without making exclusive commitments, thereby preserving its strategic autonomy and flexibility in a multipolar world. The Kingdom has also been actively engaged in discussions regarding cross-border payments innovation within broader international forums, including the G20 and the IMF, where a variety of solutions are being explored.

Finally, the costs and benefits of integrating into a complex multilateral platform like mBridge need careful consideration. These include technical integration challenges, regulatory harmonization, cybersecurity risks, and the potential for reputational implications. SAMA’s assessment may have concluded that the immediate benefits of full integration did not outweigh these considerations, or that alternative bilateral or regional digital currency initiatives might offer a more tailored and less complex path forward for certain types of transactions.

Broader Implications for Cross-Border Payments and CBDCs

Saudi Arabia’s withdrawal, while framed as a planned conclusion to a proof of concept, carries several implications for the global digital currency landscape:

• For mBridge’s Credibility: The exit of a major economy like Saudi Arabia, particularly one that had just joined as a full participant, could be perceived as a minor setback for mBridge’s ambition to become a widely adopted cross-border settlement system. While the project still boasts significant participants, a diverse and growing roster of full members is crucial for its long-term legitimacy and network effects.
• De-dollarization Narrative: mBridge is often seen as a key component in broader efforts by some nations to reduce reliance on the US dollar for international trade and finance. Saudi Arabia’s nuanced approach—exploring the project but not committing to full integration—suggests that while de-dollarization is a discussion point, nations are proceeding cautiously and pragmatically, evaluating each tool on its own merits rather than making wholesale shifts.
• CBDC Development Trends: The event highlights that central banks are still in an experimental phase regarding CBDCs. Many are exploring various models (wholesale vs. retail, bilateral vs. multilateral, DLT vs. traditional infrastructure) and are not rushing into irreversible commitments. This "learn and adapt" approach suggests a fragmented but innovative landscape where different solutions may coexist.
• Geopolitical Competition: The withdrawal will likely fuel further discussions about the geopolitical dimensions of digital finance. It underscores the difficulty of separating technological innovation from national interests and strategic alignments, especially when major powers like China and the US are involved.

China’s Broader Digital Currency Ambitions

Meanwhile, China, a driving force behind mBridge, continues to aggressively pursue its own digital currency agenda, both domestically with the digital yuan (e-CNY) and internationally. The People’s Bank of China (PBOC) has increasingly focused on the role of digital currencies, including stablecoins and CBDCs, in enhancing cross-border payments.

In June, Wang Xin, Director-General of the People’s Bank of China Research Bureau, called for closer international coordination and enhanced monitoring of stablecoins and CBDCs in cross-border payments. His remarks reflect China’s recognition of the expanding global use of these digital assets and the need for robust regulatory frameworks to manage potential risks, including financial stability and illicit finance. This call for coordination also subtly positions China as a leader in shaping the future of global digital financial governance.

These comments followed earlier moves by Chinese authorities to restrict the unauthorized issuance of renminbi-pegged stablecoins and tokenized real-world assets, including those by foreign entities. This demonstrates a clear strategy by Beijing to maintain tight control over its digital financial ecosystem and to ensure that any digital currency innovations align with its national interests and regulatory purview. China’s emphasis on controlled innovation and international cooperation, while advancing its own digital currency capabilities, indicates a long-term vision for its role in shaping the future of global finance.

The Saudi Central Bank has not provided further comment on its withdrawal beyond the initial statement cited by the Financial Times. Cointelegraph’s attempts to reach SAMA for additional clarification did not yield a response by the time of publication. The silence suggests a deliberate and carefully managed communication strategy surrounding a decision with potentially significant implications.

In conclusion, Saudi Arabia’s exit from the mBridge project, following a successful proof of concept, is not merely a technical decision but a reflection of the intricate interplay between technological exploration, national strategic interests, and the complex geopolitical currents shaping the future of global finance. As nations continue to navigate the promises and perils of digital currencies, the landscape remains dynamic, with central banks carefully charting their courses in an increasingly digital and interconnected world.
