Saudi Arabia’s central bank, SAMA, formally concluded its proof-of-concept participation in Project mBridge on May 13, 2025, according to the South China Morning Post (South China Morning Post). The move matters because Saudi participation had given the cross-border central bank digital currency project a potential link to large hydrocarbon trade flows.
The exit also arrives as mBridge is moving into a new governance phase and as U.S. sanctions pressure is drawing closer scrutiny from global banks. The combined signal is clear: faster settlement technology can improve cross-border payment rails, but it does not by itself solve the harder problems of commodity trade finance, including foreign exchange liquidity, compliance risk, bank balance-sheet capacity, and legal enforceability.
Governance and Credibility
Project mBridge was initially developed with the Bank for International Settlements through the BIS Innovation Hub Hong Kong Centre. The BIS says the project has reached the minimum viable product stage and that its role has shifted as governance moves to the participating central banks (Bank for International Settlements).
That transition changes how market participants may assess the platform. A BIS-linked experiment carries one kind of institutional profile; a rail governed by regional monetary authorities carries another. The remaining active participants named in the South China Morning Post report are the People’s Bank of China, the Hong Kong Monetary Authority, the Bank of Thailand, the Central Bank of the UAE, and the Monetary Authority of Macao (South China Morning Post).
For commercial banks, the issue is not only whether the technology works. It is whether participation can be squared with sanctions screening, correspondent banking relationships, internal risk limits, and regulatory expectations in major financial centers.
Sanctions Risk
The sanctions backdrop has become more important for any non-dollar settlement system. A Clyde & Co analysis of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 says the measure was signed into law on September 18, 2026, includes mandatory 30-day executive implementation timeframes, and expands secondary sanctions exposure for foreign entities (Clyde & Co).
The same legal analysis describes tariff mechanisms tied to energy purchasers and broader risks for foreign financial institutions involved in non-dollar trade intermediation. That does not mean every alternative settlement transaction is automatically sanctionable. It does mean banks evaluating mCBDC rails must treat legal exposure as a central design constraint, not as an afterthought.
This is why the question is no longer simply whether alternative rails can move value efficiently. Market participants are asking Can Alternative Payment Rails Bypass Secondary Sanctions?. The more relevant answer is that payment technology may change the settlement path, while sanctions compliance still follows the institutions, counterparties, goods, jurisdictions, and enforcement priorities attached to the transaction.
The Commodity Trade Finance Constraint
The strongest case for mBridge is operational: faster cross-border settlement, more direct central bank money movement, and potentially lower reliance on traditional correspondent banking routes. That case is meaningful, especially for bilateral or regional corridors.
Commodity trade finance is harder. Dollar dominance is not only a payment habit; it is supported by deep foreign exchange markets, established bank relationships, documentary trade finance practices, compliance infrastructure, and the willingness of exporters to hold the settlement currency they receive.
Saudi Arabia’s exit sharpens that distinction. Without SAMA in the project, mBridge loses a potential hydrocarbon anchor that could have helped demonstrate large-scale non-dollar commodity settlement. That does not make the platform irrelevant. It does limit the evidence available for claims that mCBDC networks can quickly displace dollar-denominated energy trade finance.
The more cautious conclusion is that mBridge remains important as a test of regional settlement architecture, while its near-term role in global commodities is likely to be narrower than the broadest de-dollarization narratives suggest. This is the core issue behind Saudi mBridge Exit: Trade Finance Fragmentation Risks: fragmentation may grow, but fragmentation is not the same as full replacement.
Watchpoints
Key uncertainties remain. Public reporting does not establish the current scale of live commercial transaction volumes flowing through the mBridge minimum viable product. It also does not yet show how foreign financial institutions using alternative settlement rails would be treated in public enforcement actions under the expanded U.S. secondary sanctions framework described by Clyde & Co.
The next important signal is the executive implementation process tied to the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026. Treasury guidance and enforcement practice will matter more than technical architecture in determining whether banks view mCBDC-based energy settlement as commercially usable or legally too exposed.
For now, Saudi Arabia’s mBridge exit is best read as a stress test for the larger thesis behind central bank digital currency settlement. The technology can reduce some payment frictions, but commodity finance still depends on liquidity, law, compliance, and institutional trust.
