BRICS Bridge: mCBDC Settlements Reshape Global Finance 2026

The BRICS Bridge mCBDC settlement system went live in early 2026, marking a potential inflection point in global finance. Built on the mBridge platform, it enables cross-border central bank digital currency payments that bypass SWIFT, and its UNIT instrument—backed 40% by gold and 60% by a basket of BRICS+ currencies—is designed to reduce dollar dependence. With the U.S. dollar's global reserve share falling to 56.9% and central banks buying over 1,100 tonnes of gold in 2025, the question is no longer whether de-dollarization is real, but how fast it is moving.

Under India's BRICS chairship, the BRICS Bridge achieved full operational status in the first quarter of 2026. It has already processed over $55.5 billion in cross-border CBDC transactions, according to platform data. Crucially, about 95% of that volume is denominated in the digital yuan, prompting debate over whether the system is a genuine multipolar alternative or a vehicle for renminbi internationalization. Saudi Arabia and the United Arab Emirates are now settling oil exports to China in yuan and exploring rupee-denominated trade with India, cracking the petrodollar model.

What is the BRICS Bridge mCBDC System?

The BRICS Bridge is a blockchain-based settlement network that allows central banks to exchange digital currencies peer-to-peer in seconds, without correspondent banks. Developed initially as mBridge by the central banks of China, Hong Kong, Thailand, the UAE, and Saudi Arabia with the BIS Innovation Hub, it now includes most BRICS+ members. Unlike SWIFT, which only sends payment messages, mBridge settles value directly. This is a critical distinction for trade finance, where delays and fees often exceed 2-3% of transaction value.

Its settlement currency, the UNIT, is a composite digital instrument backed 40% by physical gold and 60% by a basket of the yuan, rupee, ruble, real, and rand. The gold backing is intended to provide a neutral anchor and reduce volatility compared to a pure fiat basket. This design echoes the gold standard debate that has resurfaced among emerging-market central banks.

Who is Using the BRICS Bridge?

Early adopters include China, Russia, India, Saudi Arabia, the UAE, and Thailand. Russia reports that 90% of its BRICS-aligned trade now settles in local currencies, up from 40% in 2022. Saudi Arabia has signed 10-20 year yuan-denominated supply agreements with Chinese refiners, while India made its first rupee payment for UAE oil in 2025. These shifts are not yet large enough to displace the dollar, but they signal a structural change in invoicing habits.

De-dollarization in Numbers: 2025-2026

The IMF's COFER data shows the dollar's share of global foreign exchange reserves dropped to 56.9% in the third quarter of 2025, the lowest since 1994. Central banks bought over 1,100 tonnes of gold in 2025, the fourth consecutive year above 1,000 tonnes, led by Poland, India, China, and Turkey. Gold hit an all-time high of $5,595 per ounce in January 2026. These figures reinforce the multipolar currency shift that analysts have tracked since the 2022 freezing of Russian reserves.

Why Central Banks Are Diversifying

Three factors drive the move away from the dollar: sanctions risk, U.S. fiscal deterioration (debt above $38.5 trillion), and the availability of digital alternatives. The 2022 decision to freeze Russian central bank assets demonstrated that dollar reserves could be weaponized. As one G7 official told the Financial Times: The reserve system is no longer neutral. Consequently, the central bank digital currency race has accelerated across Asia and the Gulf.

Impact on Forex, Sovereign Debt, and Trade Finance

If the BRICS Bridge scales, the dollar could lose some of its 88% share of global FX turnover. A 10 percentage point decline would raise U.S. Treasury yields by 50-100 basis points, according to IMF staff estimates. That would increase U.S. government borrowing costs by roughly $150 billion annually and pressure emerging-market dollar debt. For trade finance, mBridge cuts settlement times from days to seconds and reduces fees, potentially shifting $2 trillion of annual trade flows to non-dollar rails within a decade.

The petrodollar system is the most visible casualty. Since 1974, oil has been priced in dollars, forcing importers to hold dollar reserves and recycle them into U.S. Treasuries. The UAE's April 2026 warning that it might shift yuan oil sales if dollar liquidity tightens is a direct challenge to that arrangement. However, the dollar's network effects remain powerful: it still dominates 59% of international debt issuance and 88% of FX transactions.

Expert Perspectives

Mark Carney, former Bank of England governor, describes the shift as a multipolar system where the dollar, euro, gold, and digital currencies coexist. But he cautions that the dollar's fall will be gradual. Eswar Prasad of Cornell University adds: mBridge is a real breakthrough, but its governance and transparency need to improve before it becomes a true global public good. Western regulators are responding with Project Agora, a BIS-led tokenization initiative that could fragment payments into two blocs.

Frequently Asked Questions

What is mBridge in simple terms?

mBridge is a blockchain platform that lets central banks exchange digital currencies directly, without going through SWIFT or correspondent banks. It settles in seconds and lowers costs.

Is the BRICS Bridge replacing the dollar?

Not immediately. The dollar still dominates 88% of FX transactions and 56.9% of reserves. The BRICS Bridge is a complementary rail that could erode dollar share over a decade or more.

How much gold backs the UNIT?

The UNIT is backed 40% by physical gold and 60% by a basket of BRICS+ currencies (yuan, rupee, ruble, real, rand).

Which countries are settling oil in yuan?

Saudi Arabia and the UAE are settling oil exports to China in yuan and exploring rupee trade with India. Russia already sells most of its oil in non-dollar currencies.

What does the 56.9% dollar reserve share mean?

It is the lowest since 1994 and signals a gradual diversification away from the dollar into gold, renminbi, and other currencies.

Conclusion: A Slow Unravelling, Not a Collapse

The BRICS Bridge and UNIT instrument represent a tangible step toward a multipolar monetary system. Dollar hegemony is not ending in 2026, but the structural foundations are weakening: lower reserve share, record gold purchases, and alternative payment rails now process real trade. The next 12-24 months will test whether mBridge can scale beyond yuan-dominated transactions and whether the US Treasury market absorbs the shift without a funding crisis.
