India formally assumed the BRICS chair in January 2026 and placed Central Bank Digital Currency (CBDC) interoperability at the top of the summit agenda. The Reserve Bank of India (RBI) has proposed linking the digital currencies of BRICS member states to enable direct cross-border settlements without relying on the US dollar or the SWIFT network. This initiative, if realized, could significantly accelerate de-dollarization, reduce transaction costs for over 40% of global GDP represented by BRICS+, and create an alternative financial architecture resilient to Western sanctions.
What Is BRICS CBDC Interoperability?
BRICS CBDC interoperability refers to the technical framework that allows different national central bank digital currencies — such as India's e-Rupee, Brazil's Drex, China's digital yuan (e-CNY), and Russia's digital ruble — to communicate and settle transactions directly with one another. Unlike a single shared BRICS currency, this approach preserves each nation's monetary sovereignty while enabling real-time, low-cost cross-border payments. The RBI's proposal builds on the BRICS 2025 summit call for an interconnected payment system and follows a successful India-UAE CBDC pilot in 2025.
Context: India's BRICS Chairmanship and the Push for Financial Independence
India's 2026 BRICS chairmanship, themed "Building for Resilience, Innovation, Cooperation and Sustainability," comes at a pivotal moment. The BRICS bloc now comprises 11 full members — Brazil, Russia, India, China, South Africa, Egypt, Ethiopia, Iran, UAE, Saudi Arabia, and Indonesia — plus 10 partner countries. Together, they represent 48.5% of the world's population and over 40% of global GDP in purchasing power parity terms, surpassing the G7. The dollar's share of global reserves has fallen to 56%, a 30-year low, while BRICS central banks have accumulated over 2,100 tonnes of gold since 2022.
The RBI's proposal is the most concrete step yet toward a multipolar digital payments system. According to sources familiar with the discussions, the framework focuses on creating technical links between national CBDCs rather than forming a single BRICS currency. This approach allows each member to retain full control over its monetary policy while benefiting from faster, cheaper cross-border transactions.
Technical Framework: How the CBDC Bridge Would Work
Interoperability Over a Single Currency
The proposed system would connect existing national CBDCs through a shared protocol, enabling direct peer-to-peer settlements without correspondent banks. India's e-Rupee already has over seven million retail users and 17 participating banks, with circulation surging to ₹1,016 crore by March 2025. Brazil's Drex, which integrates tokenized assets and smart contracts, is in advanced pilot stages with 16 financial consortia. China's digital yuan dominates the existing mBridge platform, accounting for 95% of its $55 billion transaction volume as of early 2026.
Building on mBridge and the India-UAE Pilot
The RBI's proposal draws on lessons from mBridge, a multi-CBDC platform developed by the central banks of China, Hong Kong, Thailand, the UAE, and Saudi Arabia, with the BIS Innovation Hub. By early 2026, mBridge had processed approximately $55 billion in transactions, settling in roughly 15 seconds at 0.3% cost — 78% less than traditional SWIFT corridors. However, the Bank for International Settlements withdrew from direct management in October 2024, citing neutrality concerns and sanctions compliance, leaving China as the dominant influence.
India's bilateral CBDC pilot with the UAE, launched in 2025, demonstrated the feasibility of direct e-Rupee-to-digital-dirham transfers. This corridor is significant given that over four million Indians live in the UAE, accounting for roughly 19% of India's total inward remittances. The success of this pilot provided the technical blueprint for the broader BRICS interoperability framework.
Impact: Accelerating De-Dollarization and Reducing Transaction Costs
If implemented, interoperable CBDCs could cut cross-border payment times from 3-5 days to seconds at near-zero cost for BRICS nations. This would be transformative for trade finance, remittances, and government-to-government transfers. The BRICS+ bloc now accounts for over a quarter of global trade, and a digital payments alternative could reduce dependence on the dollar-dominated SWIFT system.
However, internal divergences exist within the bloc. Russia and Iran strongly push for de-dollarization amid Western sanctions, while India and Brazil favor a multi-currency approach without eliminating the dollar entirely. India has clarified it does not support a common BRICS currency nor active de-dollarization, preferring instead to expand the range of settlement options available to member states.
The United States has responded with tariff threats. President Donald Trump has warned of 100% tariffs on nations working to replace the dollar's dominance, creating geopolitical friction. The US response to BRICS de-dollarization remains a key variable in the initiative's trajectory.
Expert Perspectives
"The RBI's proposal is pragmatic," said a senior official familiar with the discussions. "Rather than trying to create a single currency — which would require ceding monetary sovereignty — we are building bridges between existing systems. This is faster, cheaper, and politically feasible."
Professor Rodrigo Cezar of the Getulio Vargas Foundation noted that BRICS nations are becoming more economically significant than the G7, which accounted for only 28% of the global economy in 2024 versus BRICS's 40%. "The infrastructure for a parallel financial system is being built piece by piece," he said. "CBDC interoperability is the next logical step."
However, critics warn of fragmentation risks. A former US Treasury official, speaking on condition of anonymity, cautioned: "A fragmented global payments system could increase costs for multinational corporations and create opportunities for sanctions evasion. The US must engage constructively while protecting its interests."
Frequently Asked Questions
What is BRICS CBDC interoperability?
BRICS CBDC interoperability is a technical framework that links the central bank digital currencies of BRICS member nations — such as India's e-Rupee, Brazil's Drex, and China's digital yuan — enabling direct cross-border settlements without using the US dollar or SWIFT network.
How is this different from a single BRICS currency?
Unlike a single shared currency, interoperability preserves each nation's monetary sovereignty by connecting existing national CBDCs through a shared protocol. Members retain full control over their monetary policy while benefiting from faster, cheaper cross-border transactions.
What was the India-UAE CBDC pilot?
In 2025, India and the UAE successfully piloted a bilateral CBDC link enabling direct e-Rupee-to-digital-dirham transfers. This corridor demonstrated the technical feasibility of cross-border CBDC settlements and provided the blueprint for the broader BRICS framework.
What is mBridge and how does it relate to BRICS?
mBridge is a multi-CBDC platform developed by China, Hong Kong, Thailand, the UAE, and Saudi Arabia, with the BIS Innovation Hub. By early 2026, it had processed $55 billion in transactions. The BRICS Bridge initiative aims to build on mBridge's infrastructure to create a parallel payment architecture independent of the dollar system.
What are the main challenges to implementation?
Key challenges include internal divergences within BRICS on the pace of de-dollarization, US opposition including tariff threats, technical standardization across different CBDC platforms, regulatory compliance including anti-money laundering requirements, and the need to balance privacy with traceability.
Conclusion: A Quiet Revolution in Global Finance
The RBI's CBDC interoperability proposal represents the most concrete step yet toward a multipolar digital payments system. While a single BRICS currency remains unlikely, the technical infrastructure for a parallel financial architecture is being built piece by piece. Under India's 2026 chairmanship, the BRICS bloc is moving from discussion to implementation, with the potential to reshape global payments for over 40% of the world's economy. The coming months will reveal whether member states can overcome technical and political hurdles to turn this vision into reality.
