Saudi Arabia withdraws from China-led mBridge digital currency project amid growing geopolitical friction over dollar dominance
Saudi Arabia has officially withdrawn from the mBridge project, a sophisticated cross-border payment platform spearheaded by China, signaling a significant shift in the landscape of international finance. The decision, which confirms the kingdom’s departure as of 2025, arrives at a moment of heightened scrutiny regarding the future of the U.S. dollar as the world’s primary reserve currency. As nations explore blockchain-based alternatives to the traditional, Western-dominated SWIFT system, the mBridge project has emerged as a focal point of contention, pitting the efficiency of decentralized financial technology against the established geopolitical order of the American-led global monetary framework.
The mBridge initiative, originally conceptualized as a multi-central bank digital currency (mCBDC) arrangement, was designed to leverage distributed ledger technology to enable near-instantaneous, low-cost international settlements. By bypassing the traditional correspondent banking system, the platform effectively reduces the necessity for dollar-denominated intermediaries in cross-border trade. For many participating nations, this represents a technical breakthrough in liquidity management and transaction speed. For Washington, however, the project is increasingly viewed as a mechanism that could facilitate the evasion of U.S. financial sanctions and erode the long-term utility of the dollar.
A Chronology of Engagement and Strategic Realignment
The evolution of the mBridge project reflects a rapid acceleration in digital finance experimentation. The project originated as a collaboration between the Bank for International Settlements (BIS) Innovation Hub, the People’s Bank of China (PBOC), the Hong Kong Monetary Authority (HKMA), the Bank of Thailand, and the Central Bank of the United Arab Emirates. Saudi Arabia joined this collaborative effort in 2024, signaling a desire to modernize its financial infrastructure and diversify its international payment capabilities as part of its broader Vision 2030 economic strategy.
The timeline of the project’s scaling is marked by exponential growth in transaction volume. By October 2022, the platform had processed only 160 transactions, totaling roughly $22 million in value. However, the maturation of the underlying blockchain technology and the onboarding of new participants led to a massive surge in usage. By November 2025, the Atlantic Council reported that mBridge had facilitated 4,047 transactions, with a cumulative volume reaching $55.49 billion. This growth trajectory caught the attention of policymakers in Washington, particularly as the platform moved toward a commercial launch phase.
The Saudi government’s withdrawal in 2025, which remained undisclosed until late September 2026, occurred against a backdrop of increasing U.S. pressure on emerging markets to refrain from participating in financial architectures that challenge the dollar. While Saudi officials have maintained that the departure was a planned transition rather than a reactive measure, the timing coincides with a period of intense volatility in global trade relations.
The Geopolitical Stakes of Financial Architecture
The core of the controversy lies in the "dollar-dominated" global financial system. The SWIFT system, which processes the vast majority of international financial messages, has long served as a primary instrument of U.S. foreign policy, enabling the enforcement of sanctions against states deemed to be in violation of international norms. Proponents of mBridge argue that the system is purely about technical efficiency, aiming to reduce the friction of foreign exchange by allowing central banks to hold and trade one another’s digital currencies directly.
However, the geopolitical implications are impossible to ignore. President Donald Trump has recently taken a hardline stance against members of the BRICS economic bloc, threatening universal tariffs of up to 100% on nations that actively pursue the de-dollarization of their international trade. This threat has introduced a high-stakes calculus for U.S. allies, such as Saudi Arabia, which must balance their strategic security partnership with the United States against their economic imperative to deepen trade ties with China—the world’s largest importer of oil.
Eswar Prasad, a senior fellow at the Brookings Institution and a professor at Cornell University, notes that the dilemma facing nations like Saudi Arabia is profound. "Many U.S. allies view initiatives such as mBridge as an economic benefit and a way to lessen reliance on the dollar-dominated global financial system," Prasad observed. "But they are also acutely sensitive to U.S. pushback against initiatives seen as potentially reducing the dollar’s importance and, even worse, boosting the Chinese renminbi’s role in international finance."
Analyzing the Impact of the Saudi Exit
The Saudi Central Bank (SAMA) has remained tight-lipped regarding the specific motivations for the exit, with sources close to the matter suggesting that it would be inaccurate to infer a direct submission to U.S. pressure. Nevertheless, the withdrawal is widely interpreted by market analysts as a tactical retreat intended to preserve stability in the kingdom’s relationship with the United States.
From an economic perspective, the departure of a major global energy exporter like Saudi Arabia creates a temporary hurdle for the mBridge project. The project relies on a critical mass of diverse currencies to ensure that the liquidity pools remain functional and attractive to commercial banks. By losing a key participant, the network’s potential to provide a truly global alternative to current systems is diminished, even if only in the short term.
Furthermore, the withdrawal highlights the limitations of blockchain-based diplomacy. While the technology offers undeniable improvements in speed and cost—potentially shaving days off the settlement process for cross-border trades—the adoption of such technology is rarely a purely technical decision. It is, and remains, an extension of foreign policy. The "caution over valour" approach cited by analysts suggests that for many central banks, the risks of isolating themselves from the U.S. financial system currently outweigh the marginal gains provided by decentralized payment rails.
Future Implications for Global Trade
As the global financial system stands at this crossroads, the failure of mBridge to retain all its high-profile participants may slow the pace of de-dollarization, but it is unlikely to stop it entirely. Central banks across Asia, the Middle East, and Latin America remain committed to the development of CBDCs. The motivation to reduce dependency on a single currency system—especially one that is increasingly used as a tool of geopolitical coercion—remains a powerful driver of innovation.
Looking forward, the mBridge project will likely continue to evolve, albeit with a focus on regional integration rather than a broad, global assault on the dollar. The project has already demonstrated that the technology works at scale, with tens of billions of dollars in volume successfully settled across borders. The challenge for the BIS and the remaining project participants will be to navigate the regulatory and political minefields that have emerged in the wake of this shift.
Ultimately, the Saudi withdrawal serves as a bellwether for the broader global economy. It illustrates that in an era of "geoeconomic fragmentation," the technical infrastructure of the future will be shaped as much by the mandates of national security as by the efficiencies of the digital ledger. For businesses operating in the international space, the message is clear: the era of seamless, unified global payment systems is being challenged by a more fractured, multi-polar reality, where the currency used to settle a transaction is as important as the transaction itself.
The exit of Saudi Arabia from the mBridge program is a reminder that while innovation in financial technology is accelerating, the fundamental structures of global power remain deeply entrenched in the traditional monetary order. Whether this move is a permanent pivot or a temporary pause in a larger, inevitable shift toward digital, blockchain-based finance remains a central question for the remainder of the decade. For now, the global financial community remains in a state of watchful waiting, as the competition between legacy systems and digital alternatives continues to unfold.
