What Is Project mBridge and Why Does It Matter?
Project mBridge, a blockchain-based wholesale central bank digital currency (CBDC) settlement platform, reached live operational scale in April 2026 under India's BRICS chairship, processing over $55 billion in cross-border transactions. This milestone marks the most concrete structural shift in cross-border payments infrastructure in decades, bypassing the SWIFT network and reducing reliance on the US dollar. The platform, originally developed by the Bank for International Settlements (BIS) Innovation Hub alongside central banks from China, Hong Kong, Thailand, the UAE, and Saudi Arabia, has evolved from a 2022 pilot with $22 million in transactions to a fully operational system handling $55.49 billion across 4,047 transactions by late 2025. The BRICS de-dollarization strategy has found its most powerful tool in mBridge, which enables real-time, peer-to-peer settlement in central bank digital money, eliminating the need for costly correspondent banking networks.
How mBridge Challenges the Correspondent Banking Architecture
Traditional cross-border payments rely on a chain of correspondent banks, each holding pre-funded nostro/vostro accounts—an estimated $10 trillion in idle liquidity globally. mBridge replaces this with a shared distributed ledger where commercial banks transact directly using wholesale CBDCs issued by their respective central banks. Settlement is atomic and final, cutting transaction times from days to seconds and reducing costs by up to 50%. The platform's mBridge Ledger is compatible with the Ethereum Virtual Machine, allowing smart contract functionality for automated foreign exchange and trade finance. China's digital yuan (e-CNY) now accounts for over 95% of settlement volume on the platform, demonstrating the digital yuan dominance in this new payment corridor. The UAE Ministry of Finance has already executed government transactions using wholesale digital dirham on mBridge, proving its viability for public sector payments.
Strategic Implications for the Dollar's Reserve Status
The operationalization of mBridge coincides with a historic decline in the US dollar's global reserve share, which fell below 57% for the first time in three decades—dropping to 56.3% in Q1 2026 according to IMF data. This eight-quarter consecutive decline is driven by three factors: the weaponization of financial sanctions (notably the freezing of $300 billion in Russian reserves in 2022), US fiscal deterioration with debt exceeding $39 trillion, and the BRICS+ expansion now representing over 40% of global GDP. While the dollar still settles 88% of forex transactions, the declining dollar reserve share signals a gradual diversification rather than collapse. BRICS+ has launched complementary initiatives including BRICS Pay, a cross-border settlement platform bypassing SWIFT, and 'The Unit,' a gold-backed digital settlement token processing $2.5 billion monthly on a Cardano blockchain. China's CIPS network processed ¥180 trillion in 2025 (up 43%), and Saudi Arabia now prices 22% of its China crude exports in yuan.
Risks and Opportunities for Global Trade and Financial Stability
For global trade, mBridge offers unprecedented efficiency gains. Energy and commodities transactions are increasingly settled on the platform, reducing costs for emerging economies that previously paid premium fees for dollar-denominated clearing. However, the fragmentation of payment systems poses risks. The BIS, which handed governance of mBridge to participating central banks in October 2024, has launched a separate project with Western central banks including the Federal Reserve and ECB, signaling a potential bifurcation of global payments infrastructure. This global payments fragmentation could increase transaction costs for countries operating across both systems and complicate sanctions enforcement. For financial stability, the shift away from dollar-based settlement reduces the transmission of US monetary policy shocks but introduces new risks around the governance of multiple CBDC platforms and the potential for liquidity fragmentation.
Expert Perspectives
"mBridge is not directly challenging dollar dominance—it is building parallel settlement rails that incrementally erode reliance on dollar-based systems across specific corridors and sectors," notes a senior analyst at the Atlantic Council. "The $55 billion in transactions is still small relative to the $2 trillion daily SWIFT volume, but the growth trajectory is exponential." Former RBI Governor Shaktikanta Das, who oversaw India's CBDC pilot, stated: "Under India's BRICS chairship, we are committed to creating a more inclusive and efficient global financial architecture. mBridge demonstrates that technology can reduce the friction that has long plagued cross-border payments."
Frequently Asked Questions
What is Project mBridge?
Project mBridge is a multi-CBDC platform built on distributed ledger technology that enables real-time, peer-to-peer cross-border payments and foreign exchange transactions directly between commercial banks using wholesale central bank digital currencies.
How much volume has mBridge processed?
As of late 2025, mBridge had processed $55.49 billion across 4,047 transactions, a massive increase from $22 million across 160 transactions in October 2022.
Which countries participate in mBridge?
Founding participants include central banks from China, Hong Kong, Thailand, the UAE, and Saudi Arabia. Over 30 observing members include central banks from around the world.
Does mBridge replace SWIFT?
Not yet. mBridge operates parallel to SWIFT for specific corridors and transaction types, primarily trade settlement in energy and commodities. It reduces reliance on SWIFT but does not fully replace it.
What is the dollar's reserve share in 2026?
The US dollar's share of global foreign exchange reserves fell to 56.3% in Q1 2026, the lowest level in 30 years, according to IMF data.
Conclusion and Future Outlook
The live operationalization of mBridge under India's BRICS chairship represents a pivotal moment in the evolution of global payments. While the dollar remains dominant, the infrastructure for a multipolar financial system is now operational. Central banks worldwide are watching closely, and the BIS's parallel project with Western central banks suggests that CBDC-based cross-border payments will become the norm rather than the exception. The next 12 months will be critical in determining whether mBridge remains a niche corridor or expands to become a genuine alternative to the dollar-based system.
