Saudi Arabia Ends Participation in mBridge After Proof-of-Concept Completion

Saudi Arabia’s central bank formally withdrew from the China-backed mBridge cross-border CBDC platform on May 13, 2025, concluding a proof-of-concept that began when SAMA joined as a full participant in June 2024. The move, reported by the Financial Times and confirmed by a statement from SAMA, marks the latest shift in the geopolitical landscape of digital-currency collaboration and comes as the project faces heightened scrutiny from U.S. policymakers.

Context: mBridge’s Genesis and Architecture

mBridge was launched in 2021 through a joint effort by the Bank for International Settlements (BIS) Innovation Hub and the central banks of China, Hong Kong, Thailand, and the United Arab Emirates. Its core design departs from a single stablecoin model; instead, each participating central bank can issue its own digital currency on a shared distributed ledger. This architecture is intended to streamline cross-border payments, reduce settlement latency, and lower transaction costs for both wholesale and retail flows.

The BIS oversaw development until October 2024, when it transferred operational control to the participating central banks after the platform reached a minimum viable product (MVP) stage. BIS General Manager Agustín Carstens emphasized that the handover was not politically motivated, underscoring the technical rather than strategic nature of the transition.

Impact on Regional Digital-Currency Cooperation

Saudi Arabia’s exit reduces the number of Gulf participants in mBridge to a single member—the United Arab Emirates. For the Gulf Cooperation Council (GCC), the withdrawal may slow momentum toward a unified digital-payments corridor that could have linked Riyadh, Abu Dhabi, and Doha with Asian markets. The UAE’s continued involvement suggests a partial commitment, but the loss of Saudi participation weakens the consortium’s bargaining power in negotiations with China and other major economies.

From a market perspective, the departure signals to investors that Saudi authorities are exercising caution in aligning with projects perceived as facilitating sanctions evasion. The U.S.-China Economic and Security Review Commission’s 2024 report warned that mBridge could become an alternative settlement system for entities seeking to bypass U.S. sanctions. Saudi Arabia’s decision, therefore, may be read as an effort to avoid entanglement in that regulatory risk.

Regulatory and Geopolitical Risks

The United States has increasingly flagged cross-border CBDC initiatives that could undermine its sanctions regime. While the Financial Times article notes that the BIS departure was not politically driven, the broader environment remains fraught. U.S. policymakers have called for greater transparency and coordination on digital-currency projects that involve Chinese state-linked institutions.

Saudi Arabia’s stated intention to end participation was pre-planned, according to the central bank’s statement, but the timing aligns with intensified U.S. scrutiny. Should the U.S. introduce formal sanctions or export-control measures targeting mBridge participants, remaining members could face compliance challenges, especially if they rely on U.S.-based financial infrastructure.

Operational Consequences for mBridge

With Saudi Arabia out, the platform loses a major source of liquidity and a potential gateway to the Middle East’s $2 trillion remittance market. The proof-of-concept phase demonstrated the ability to settle cross-border payments using each central bank’s digital token, but scaling the solution now requires either new participants or deeper integration with existing members.

The BIS’s earlier handover to the central banks means that future development will be funded and governed by the remaining consortium. This could lead to slower innovation cycles unless the UAE and China increase their resource commitments. The project’s roadmap, which anticipated broader adoption across Asia, the Middle East, and Europe, may need revision to reflect a narrower participant base.

Market Reaction and Price Signals

Crypto-market data on September 21, 2026 shows Bitcoin trading near $86,960, with major altcoins posting double-digit gains. While the mBridge news did not trigger a sharp move in the broader crypto market, analysts note that any indication of reduced Chinese influence in cross-border digital-currency infrastructure can temper speculative inflows into China-linked stablecoins and CBDC-related tokens.

Institutional investors with exposure to sovereign digital-currency projects should monitor the evolving regulatory stance in the U.S. and Europe. The recent launch of the European Central Bank’s Pontes platform, which settles tokenized assets in central-bank money, illustrates a parallel effort to build sovereign-backed settlement layers without relying on private stablecoins. See the ECB Pontes platform launch for a contrasting approach.

What to Watch Next

  • Further withdrawals or new entrants: If other Gulf or Asian central banks reassess their involvement, mBridge could either contract further or seek new partners to maintain network effects.
  • U.S. policy developments: Any legislative or regulatory action targeting cross-border CBDC collaborations with Chinese entities will directly affect the remaining participants.
  • Technical milestones: The next phase of mBridge development—moving from MVP to production-grade deployment—will reveal whether the platform can sustain itself without Saudi backing.
  • Alternative sovereign solutions: The ECB’s Pontes platform and other BIS-initiated projects may attract participants seeking a multilateral settlement system less exposed to geopolitical risk.

Risk Assessment for Market Participants

For banks and fintech firms eyeing integration with mBridge, the immediate risk is reduced network liquidity and heightened compliance scrutiny. Companies should conduct enhanced due-diligence on counterparties, especially those based in jurisdictions with active U.S. sanctions enforcement. Crypto investors should treat any token linked to mBridge’s digital currencies as speculative, given the uncertain adoption trajectory.

Conclusion

Saudi Arabia’s exit from the mBridge CBDC project underscores the delicate balance central banks must strike between technological innovation and geopolitical risk. While the proof-of-concept phase demonstrated technical feasibility, the loss of a major Gulf participant may delay the platform’s ambition to become a global alternative to existing SWIFT-based settlement systems. Stakeholders should monitor regulatory signals from the United States and Europe, watch for potential new entrants, and evaluate the broader shift toward sovereign-backed tokenized settlement infrastructures.
