BRICS Bridge: How CBDC Settlement Reshapes Finance in 2026

In early 2026, under India's BRICS chairship, the mBridge blockchain platform reached full operational status — a milestone that financial historians may one day regard as the moment the dollar-centric payments system faced its first structural competitor since Bretton Woods. The platform, which enables real-time cross-border settlement in central bank digital currencies (CBDCs), has processed over $55.5 billion in transactions, cutting settlement times from days to seconds and bypassing the SWIFT messaging system entirely. "This is no longer a pilot or a proof-of-concept," said a senior official at the Hong Kong Monetary Authority. "mBridge is settling real trade, every day, at scale."

The Architecture of a Parallel System

mBridge — short for Multiple CBDC Bridge — was developed by the central banks of China, Hong Kong, Thailand, the United Arab Emirates, and Saudi Arabia, with initial support from the BIS Innovation Hub. Unlike SWIFT's messaging model, which routes payment instructions through layers of correspondent banks, mBridge operates on a shared distributed ledger where settlement is atomic, peer-to-peer, and final within seconds. Commercial banks connect directly to the platform, using wholesale CBDCs issued by participating central banks, eliminating the need for pre-funded nostro accounts that tie up an estimated $10 trillion globally.

The cost differential is stark. Traditional correspondent banking imposes fees of $5 to $25 per intermediary hop, with hidden foreign-exchange margins and settlement delays of three to five days. On mBridge, transactions settle at near-zero marginal cost. The platform supports the digital yuan (e-CNY), Hong Kong dollar, Thai baht, UAE dirham, and Saudi riyal. India's e-Rupee is expected to join later in 2026, and over 30 central banks are observing the project. However, one figure underscores the platform's asymmetry: approximately 95% of mBridge volume is denominated in digital yuan, raising questions about whether the system is a genuine multipolar alternative or a vehicle for renminbi internationalisation.

De-dollarisation by the Numbers

The operational launch of mBridge coincides with a steady erosion of the dollar's reserve dominance. According to IMF COFER data, the dollar's share of global foreign exchange reserves fell to 56.3% in the first quarter of 2026, down from 71% in 2000 and the lowest level since 1995. Central banks purchased over 1,000 tonnes of gold in 2025 alone, and gold holdings now exceed U.S. Treasury holdings in aggregate for the first time. BRICS+ nations, which now represent more than a quarter of the global economy after Indonesia's accession in 2025, settle approximately 67% of intra-bloc trade in local currencies.

Saudi Arabia has emerged as a pivotal case study. In 2024, Riyadh allowed its 50-year-old petrodollar understanding with Washington to lapse. By early 2026, the Kingdom was settling an estimated 22% of its China-bound crude oil exports in yuan, with some analysts placing the figure closer to 45%. The Saudi Central Bank joined mBridge in 2024 and has conducted live eSAR settlements via the platform. "The petrodollar wasn't killed overnight," noted an energy-market strategist at a Gulf-based investment bank. "But it is being unwound, cargo by cargo, contract by contract."

Geopolitical Ramifications: Sanctions, Sovereignty, and Fragmentation

The strategic calculus behind mBridge is inseparable from the weaponisation of dollar-denominated payment infrastructure. The 2022 freeze of roughly $300 billion in Russian central bank reserves — and subsequent efforts to use those assets to fund Ukraine — served as a catalyst for non-Western central banks to seek alternatives. "Every reserve manager saw what happened to Russia and asked: could this happen to us?" said a former IMF official now advising Southeast Asian monetary authorities. The answer, for a growing number of countries, has been to build redundancy into their payment rails.

The Atlantic Council GeoEconomics Center warned in a 2026 report that global payment systems are fragmenting along geopolitical lines, driven by the interplay of market forces, technological divergence, regulatory gaps, and — critically — the use of payment infrastructure as a coercive tool. The IMF has similarly cautioned that fragmentation could raise the cost of cross-border payments, reduce transparency, and complicate financial stability oversight. The G20, under the U.S. presidency in 2026, faces pressure to address the issue before the 2027 deadline of its Cross-Border Payments Roadmap.

For Western policymakers, the implications are sobering. A reduced role for the dollar in trade settlement diminishes the reach of U.S. sanctions. It also threatens to raise U.S. borrowing costs if foreign demand for Treasuries wanes — a risk already flagged by the Treasury Borrowing Advisory Committee. "The dollar is not about to be dethroned," said a senior fellow at the Peterson Institute for International Economics. "But the erosion of its network effects is real, and the slope of that erosion has steepened in 2026."

The Limits of the Shift

For all its symbolic and operational significance, the BRICS Bridge faces structural constraints. The dollar remains involved in 88% of global foreign-exchange transactions; the yuan accounts for just 2.8% of allocated reserves. U.S. Treasury markets remain the deepest and most liquid in the world, with no credible substitute. And mBridge, for all its technological sophistication, is still a fraction of SWIFT's daily volume of over $2 trillion.

Internal BRICS dynamics also complicate the narrative. India and China — the bloc's two largest economies — have divergent strategic interests, and governance of the mBridge platform has already exposed tensions over yuan dominance. Several member states, including Brazil and South Africa, are at early stages of CBDC development, limiting their near-term participation. Meanwhile, the BIS has launched a parallel wholesale CBDC initiative, Project Agorá, with Western central banks, raising the prospect of a fragmented, two-track global payments architecture.

Moreover, the BRICS Contingent Reserve Arrangement remains untested in a crisis, and the bloc's ability to provide a genuine lender-of-last-resort function is unproven. "You can build the pipes," said a London-based emerging-markets economist, "but without the liquidity backstop and the legal frameworks, you haven't built a system — you've built a channel."

Frequently Asked Questions

What is the BRICS Bridge (mBridge)?

mBridge is a blockchain-based wholesale CBDC settlement platform that allows commercial banks to execute cross-border payments and foreign-exchange transactions directly, in real time, without passing through the correspondent banking network or SWIFT. It was developed by the central banks of China, Hong Kong, Thailand, the UAE, and Saudi Arabia, and reached full operational scale in early 2026.

How much has mBridge processed so far?

As of early 2026, mBridge has processed over $55.5 billion in cumulative transaction volume across more than 4,000 individual transactions — a roughly 2,500-fold increase from its initial 2022 pilot, which handled $22 million.

Is mBridge replacing SWIFT?

Not in the near term. mBridge handles a tiny fraction of SWIFT's daily volume. However, it represents the first operational, at-scale alternative to the dollar-centric correspondent banking model for participating jurisdictions, and its growth trajectory has accelerated since the BIS handed governance to member central banks in late 2024.

What does this mean for the U.S. dollar?

The dollar's dominance is eroding at the margins: its share of global reserves has fallen below 57%, and a growing share of BRICS trade is settled in local currencies. However, the dollar retains unmatched depth in foreign-exchange and bond markets, and no single currency — not the yuan, euro, or any other — is positioned to replace it as the primary global reserve asset.

Which countries are involved in mBridge?

The founding participants are China, Hong Kong (as a special administrative region), Thailand, the United Arab Emirates, and Saudi Arabia. India is expected to join with its e-Rupee in 2026. More than 30 central banks are observing the project, and BRICS members are working to link all member CBDCs to the platform.

Outlook: Erosion, Not Collapse

The launch of the BRICS Bridge in 2026 does not herald the end of dollar hegemony, but it marks the beginning of a genuinely multipolar payments landscape. For the first time since the establishment of the Bretton Woods framework, a coalition of systemically important economies has built and deployed a functional alternative to the dollar-centric clearing infrastructure — not as a theoretical construct, but as a live production system settling billions of dollars in real trade. The question for the remainder of this decade is not whether de-dollarisation will accelerate, but at what pace, and whether the Western-led financial architecture can adapt before the ground beneath it shifts irreversibly.
