mBridge Revolution: How BRICS CBDCs Are Reshaping Global Finance

In April 2026, under India's BRICS chairship, Project mBridge—the world's first multi-central bank digital currency (CBDC) settlement platform—transitioned from pilot to full operational status. Processing over $55 billion in cross-border transactions and enabling near-zero-cost settlement in roughly 15 seconds, mBridge represents the most concrete institutional challenge to dollar hegemony in decades. For the first time since the Bretton Woods system was established, a viable, blockchain-based alternative to the SWIFT messaging network is processing real trade flows at scale.

What Is mBridge and How Does It Work?

mBridge is a blockchain-based wholesale CBDC platform that enables real-time, peer-to-peer cross-border payments and foreign exchange transactions between participating central banks and commercial banks. Originally developed in 2021 by the Bank for International Settlements (BIS) Innovation Hub, the Hong Kong Monetary Authority, the Bank of Thailand, the Digital Currency Research Institute of the People's Bank of China, and the Central Bank of the UAE—with Saudi Arabia joining in June 2024—the platform operates on a distributed ledger called the mBridge Ledger. Unlike the correspondent banking system, which routes payments through multiple intermediary banks over 3–5 days at fees of 6–8%, mBridge settles transactions in seconds at a fraction of the cost, bypassing the dollar and SWIFT entirely.

The platform's operational leap has been staggering. From a modest $22 million in transactions during its 2022 pilot, mBridge processed over 4,000 transactions worth $55.5 billion by early 2026. China's digital yuan (e-CNY) dominates settlement volume at approximately 95%, reflecting Beijing's first-mover advantage in the central bank digital currencies race. However, the broader implications extend far beyond Chinese dominance: mBridge has created a functioning alternative rail for cross-border value transfer that does not touch the US financial system.

The Scale of the Shift: By the Numbers

The operationalization of mBridge coincides with a cascade of milestones signaling the most rapid de-dollarization trend since the collapse of Bretton Woods:

• Dollar reserve share: IMF COFER data shows the US dollar's share of global foreign exchange reserves fell to 56.3% in Q1 2026, its lowest level since 1995 and down from over 71% in 2000.
• Intra-BRICS local currency trade: 67% of trade among the bloc's 11 members now settles in local currencies, up from negligible levels a decade ago.
• Central bank gold purchases: Central banks bought a record 1,237 tonnes of gold in 2025—the third consecutive year above 1,000 tonnes—pushing global sovereign gold reserves above 38,000 tonnes.
• US Treasury holdings: Foreign holdings of US Treasuries have declined from $7.2 trillion to approximately $6.5 trillion, with China alone reducing its position to $688.7 billion by late 2025.
• Petroyuan milestone: Saudi Arabia now settles approximately 22% of its crude exports to China in digital yuan, challenging the 1974 petrodollar arrangement.

These figures are not isolated data points. They form a coherent picture of a world gradually diversifying away from dollar-centric infrastructure—and mBridge provides the plumbing to accelerate that transition.

Geopolitical Ramifications: A Bifurcating Financial System

Why the BIS Withdrew

In October 2024, the BIS announced its withdrawal from the mBridge project. BIS General Manager Agustín Carstens framed the exit as a natural transition—arguing the project had "reached sufficient maturity" for participating central banks to operate independently. However, the timing was widely interpreted as a response to the 16th BRICS summit in Kazan, where members discussed adapting mBridge's architecture into a "BRICS Bridge" capable of sanctions evasion. Carstens later acknowledged that mBridge "was not created to serve BRICS and cannot be a means to violate sanctions," but the damage was done. The platform's participants proceeded without BIS oversight, and the governance framework—equal voting rights among members—remained intact.

The West's Answer: Project Agorá

The BIS did not retreat from the CBDC space. In 2025, it launched Project Agorá, a parallel initiative with seven G7 central banks and over 40 financial institutions—including JPMorgan, Citi, HSBC, Mastercard, Visa, and SWIFT. Agorá aims to tokenize wholesale payments with atomic settlement, and it entered testing in early 2026. However, Agorá remains a prototype, while mBridge is live and scaling. As Forbes noted in May 2026: "After mBridge and Agora, multilateral CBDC interoperability is dead." The world is witnessing the emergence of two non-interoperable payment blocs—one anchored by the dollar and Western institutions, the other by the digital yuan and BRICS+ infrastructure.

The Complementary Ecosystem: BRICS Pay and The Unit

mBridge does not operate in isolation. Under India's 2026 chairship, BRICS has advanced a suite of complementary systems. BRICS Pay—a decentralized cross-border payment network integrating national rails like Brazil's Pix, Russia's SPFS, China's CIPS, and India's UPI—is scheduled for launch at the 2026 BRICS summit. Built on a hubless, sanctions-resistant architecture capable of processing 20,000 transactions per second, BRICS Pay represents the retail-facing complement to mBridge's wholesale infrastructure.

Meanwhile, "The Unit"—a gold-backed digital settlement token backed 40% by physical gold and 60% by a basket of BRICS currencies—launched on a permissioned Cardano-based blockchain in early 2026. Processing approximately $2.5 billion monthly in energy and commodity trades, The Unit settles transactions in under 10 seconds and provides a non-dollar store of value for intra-bloc settlement. Together, mBridge, BRICS Pay, and The Unit form a layered architecture: wholesale CBDC settlement, retail payment integration, and commodity-anchored value storage.

Expert Perspectives

Economists remain divided on the durability of the shift. "This is not the death of the dollar," cautions one senior IMF official, noting that the greenback still accounts for 88% of global FX turnover and roughly half of SWIFT payments. "But it is the birth of something genuinely new—a parallel system that didn't exist five years ago."

Former Bank of England Governor Mark Carney has described the move toward a multipolar reserve system—dollar, euro, gold, and digital currencies—as "irreversible." Analysts at CommandEleven Intelligence project 2026–2030 as the "Bifurcation of Global Capital" period, during which BRICS+ members, growing at 3.7% versus the G7's 1.1%, will increasingly route trade through independent financial rails.

Yet risks abound: China's 95% share of mBridge volume raises governance concerns among smaller members; the BIS withdrawal removed a neutral arbiter; and the lack of interoperability between mBridge and Agorá means businesses operating across blocs face mounting compliance complexity. The global payment system fragmentation threatens to increase transaction costs for firms caught between competing standards.

Frequently Asked Questions

What is mBridge and who operates it?

mBridge is a blockchain-based platform for cross-border settlement using wholesale central bank digital currencies (CBDCs). It is jointly operated by the central banks of China (via its Digital Currency Research Institute), Hong Kong, Thailand, the UAE, and Saudi Arabia. The BIS helped develop it but withdrew in October 2024.

How does mBridge bypass SWIFT?

mBridge uses its own distributed ledger—the mBridge Ledger—to record and settle transactions directly between participating banks, eliminating the need for SWIFT messaging and correspondent banking intermediaries. Settlement occurs peer-to-peer in CBDCs rather than through dollar-denominated nostro/vostro accounts.

Is mBridge a threat to the US dollar?

mBridge facilitates settlement in non-dollar currencies, primarily the digital yuan. While its $55 billion volume is modest compared to SWIFT's $2.5 trillion daily traffic, it provides an institutional-grade alternative that didn't exist before. Combined with declining dollar reserve share and record gold buying, it contributes to a gradual erosion of dollar dominance rather than an imminent collapse.

What is the difference between mBridge and BRICS Pay?

mBridge is a wholesale CBDC platform for large-value interbank settlement. BRICS Pay is a retail-focused payment network integrating national systems (Pix, UPI, CIPS, SPFS) for everyday cross-border transactions. Both bypass SWIFT and the dollar, but they operate at different layers of the financial stack.

Why did the BIS leave mBridge?

The BIS withdrew in October 2024 after the BRICS Kazan summit proposed a "BRICS Bridge" using mBridge's architecture for sanctions-evading payments. While BIS characterized the exit as a natural transition milestone, the geopolitical optics—and subsequent independent operation by BRICS-aligned central banks—underscored the project's shift away from Western institutional oversight.

Conclusion: The Road Ahead

The operationalization of mBridge under India's 2026 BRICS chairship marks a watershed moment in the history of global finance. For the first time, a non-Western, blockchain-based institutional payment system is processing real trade flows at scale—bypassing the dollar, SWIFT, and the correspondent banking network that has underpinned international commerce for half a century. The dollar is not collapsing; its network effects, deep capital markets, and institutional trust remain formidable. But the monopoly is cracking. As BRICS expands, gold reserves accumulate, and alternative payment rails harden into permanent infrastructure, the question is no longer whether the global financial architecture will bifurcate—but how quickly, and at what cost to the institutions that built the old order.
