Saudi Arabia exits mBridge CBDC project

TLDR

Saudi Arabias central bank has ended its participation in the China-backed mBridge cross-border CBDC platform after completing a planned proof of concept.

1. Saudi Arabia joined mBridge in 2024, ran tests, and then exited in May 2025, saying its involvement was meant to be temporary.
2. mBridge continues with China, Hong Kong, Thailand, UAE and others, but Saudis exit weakens the narrative of a broad anti dollar settlement bloc.
3. For crypto users, the move highlights how CBDC payment networks and stablecoins compete or coexist as alternative cross-border rails to SWIFT and the dollar system.

Deep Dive

1. What Saudi Arabia Did And Why

The Saudi Central Bank (SAMA) joined mBridge as a full participant in June 2024, then completed a proof of concept on May 13, 2025 and announced it would end participation as planned, according to a statement cited by the Financial Times and summarized by Cointelegraph.

Reports from CryptoBriefing describe mBridge as the mBridge Ledger, a blockchain based, EVM compatible platform for real value cross border payments and foreign exchange between central banks using their own CBDCs.

Saudis exit does not shut down mBridge. The original core group China, Hong Kong, Thailand and UAE, plus later entrants such as Macau, remain active on the platform.

Confidence: high because multiple independent outlets report matching timelines, participants and quotes.

2. Geopolitics, De Dollarisation And Sanctions

The project has drawn scrutiny in Washington. A US China Economic and Security Review Commission report warned that mBridge could become an alternative cross border settlement system for countries looking to avoid US sanctions, as noted in Cointelegraphs coverage.

Analysts quoted by the South China Morning Post see Saudis withdrawal more as a political signal than a technical failure. It slightly dents the story of a broad anti dollar coalition while leaving the core Asia and Gulf participants intact.

Saudi can still watch mBridge from the sidelines and pursue other payment modernization routes, so this is more about optics and alignment than about abandoning CBDC experimentation.

3. Implications For Crypto And Payment Rails

CBDCs like those used on mBridge are not cryptocurrencies, but they do use blockchain type infrastructure and compete directly with stablecoins and tokenized bank deposits for cross border settlement.

Saudis planned exit reinforces that major countries are testing multiple models in parallel wholesale CBDC, deposit tokens, and private stablecoins rather than converging quickly on one global alternative. That keeps room for USD stablecoins and public chain settlement to remain dominant in crypto trading and DeFi.

For crypto users, the practical angle is to watch where real cross border volume migrates. If mBridge and similar CBDC networks stay narrow and regional, stablecoins and public chains should continue to carry most global crypto liquidity.

Conclusion

Saudi Arabias departure narrows the political scope of mBridge but leaves its technical roadmap largely intact, shifting it toward a more regional CBDC corridor.

For crypto markets, this lowers the odds of a rapid pivot away from dollar based and stablecoin based settlement, while confirming that central banks are still actively experimenting with blockchain infrastructure in parallel to public crypto rails.
