BRICS CBDC Interlink: India's Concrete De-Dollarization Move

In January 2026, the Reserve Bank of India (RBI) formally proposed linking the central bank digital currencies (CBDCs) of BRICS nations — including the digital rupee, digital yuan, and digital ruble — into an interoperable cross-border payment system designed to bypass SWIFT and reduce dependence on the US dollar. This initiative, set to be a centerpiece of the 2026 BRICS summit chaired by India, represents the most concrete infrastructure move toward a multipolar monetary system in decades.

What Is the BRICS CBDC Interlink Proposal?

The RBI's proposal calls for connecting the existing CBDCs of BRICS member states — India's e-Rupee, China's e-CNY, Russia's digital ruble, Brazil's Drex, and others — through a shared technical platform that enables direct peer-to-peer settlements without intermediaries. Unlike earlier discussions of a single BRICS currency, this approach preserves each nation's monetary sovereignty while creating practical payment infrastructure. According to sources cited by Reuters, the proposal leverages settlement cycles and forex swap lines to facilitate real-time cross-border transactions.

India is drawing on its experience with the Unified Payments Interface (UPI), which processed 21.63 billion transactions in December 2025 alone, as a blueprint for the system. The BRICS payment infrastructure would operate independently of SWIFT, which has been weaponized through sanctions on Russia and Iran.

Why Now? The Dollar's Declining Dominance

The dollar's share of global foreign exchange reserves has fallen to 56.32% as of Q2 2025 — its lowest level in 30 years, according to IMF COFER data. This represents a structural decline from 72% in 2001, driven by multiple factors:

• Weaponization of dollar assets: The freezing of $300 billion in Russian reserves in 2022 prompted central banks worldwide to diversify.
• Record central bank gold purchases: Central banks bought 1,237 tonnes of gold in 2025, with gold's share of reserves doubling to over 23%.
• Rise of digital alternatives: Project mBridge, a China-backed CBDC platform, has processed over $55.49 billion in transactions — a 2,500-fold increase from its 2022 pilot.
• Intra-BRICS local currency settlement: Local currency trade among BRICS nations has reached 60-67% in some corridors.

The declining dollar reserve share has accelerated since 2022, though the dollar still settles approximately 88% of global forex transactions and remains deeply entrenched in global finance.

Project mBridge: The Proof of Concept

Project mBridge, initially developed within the Bank for International Settlements (BIS) Innovation Hub, has demonstrated the viability of CBDC-based cross-border payments. By November 2025, the platform had processed 4,047 transactions worth $55.49 billion, with China's digital yuan accounting for over 95% of settlement volume. The BIS transferred governance to participating central banks in October 2024, and the platform has since entered live government use, including a transaction by the UAE's Ministry of Finance using wholesale digital dirhams.

mBridge's success provides a template for the broader BRICS CBDC interlink. However, the Project mBridge expansion has been dominated by China, raising concerns about Beijing's influence over the system.

How the BRICS CBDC Interlink Would Work

The proposed system would operate on three layers:

1. CBDC issuance layer: Each member state issues its own digital currency through its central bank.
2. Interoperability layer: A shared protocol enables direct conversion between CBDCs using smart contracts and forex swap lines.
3. Settlement layer: Transactions are settled in real-time using a distributed ledger, bypassing correspondent banks and SWIFT.

This architecture reduces transaction costs, settlement times, and geopolitical risk. The CBDC interoperability standards being developed by BRICS could set a precedent for other emerging economies.

Political Dynamics Within BRICS

The proposal has exposed differing priorities among BRICS members. Russia and Iran, both under heavy Western sanctions, strongly advocate for full de-dollarization. India and Brazil, however, favor a multi-currency approach that reduces dollar dependence without eliminating it entirely. China, while supporting the initiative, benefits from the current system and is wary of disrupting financial stability.

The United States has warned of 100% tariffs on BRICS nations actively working to replace the dollar, but such threats have further motivated the bloc to develop alternative systems. The BRICS de-dollarization strategy reflects a broader shift toward financial multipolarity.

Impact on Global Financial Architecture

If implemented, the BRICS CBDC interlink could reshape global finance in several ways:

• Reduced dollar demand: As BRICS trade settles in local currencies, demand for dollar-denominated assets could decline.
• Fragmentation of payment systems: The world could split into competing digital currency blocs — dollar, euro, yuan, and BRICS.
• Sanctions evasion: Nations under Western sanctions could bypass SWIFT entirely.
• New Development Bank role: The NDB aims to lend one-third of its portfolio in member domestic currencies by 2026.

The multipolar monetary system is no longer a theoretical concept but a practical infrastructure project.

Expert Perspectives

"This is the most concrete de-dollarization move we have seen," said Eswar Prasad, a former IMF official and professor at Cornell University. "The BRICS CBDC interlink addresses the infrastructure gap that has long hindered alternative payment systems. If successful, it could fundamentally alter the geography of global finance."

However, Josh Lipsky, director of the Atlantic Council's GeoEconomics Center, cautioned: "Project mBridge shows the technical feasibility, but scaling to the entire BRICS bloc faces enormous political and regulatory hurdles. The dollar's network effects remain powerful."

Frequently Asked Questions

What is the BRICS CBDC interlink?

The BRICS CBDC interlink is a proposed system to connect the central bank digital currencies of BRICS nations — including India's digital rupee, China's digital yuan, and Russia's digital ruble — into an interoperable cross-border payment network that bypasses SWIFT and reduces reliance on the US dollar.

When was the proposal made?

The Reserve Bank of India formally proposed the interlink in January 2026, ahead of India's chairmanship of the BRICS summit later that year.

How is this different from a single BRICS currency?

Rather than creating a single shared currency, the proposal focuses on interoperability between existing national digital currencies, preserving each country's monetary sovereignty while enabling direct transactions.

What is Project mBridge?

Project mBridge is a China-backed cross-border payments platform that has processed over $55 billion in transactions using CBDCs. It serves as a proof of concept for the broader BRICS interlink.

Will the dollar lose its reserve status?

While the dollar's reserve share has fallen to a 30-year low of 56.32%, most analysts expect a gradual transition to a multipolar system rather than a sudden collapse. The dollar remains deeply entrenched in global finance.

Conclusion: A Pivotal Moment for Global Finance

The 2026 BRICS summit in India will be a defining moment for the future of the global monetary system. With the dollar's dominance eroding, central bank gold purchases at record levels, and digital currency infrastructure maturing, the BRICS CBDC interlink represents the most ambitious attempt yet to build an alternative financial architecture. Whether it gains lasting traction among emerging economies will depend on technical execution, political will, and the response from Western financial powers.
