BRICS Summit 2026: India's Proposal for Digital Currency Link

Conceptual clarity:
The Reserve Bank of India (RBI) has proposed linking the official central bank digital currencies (CBDCs) of BRICS countries to facilitate cross-border trade and tourism payments. This proposal focuses on interoperability between national digital currencies—such as India’s e-rupee, China’s e-CNY, or Brazil’s digital real—rather than creating a single supranational BRICS currency. Each country would retain full monetary sovereignty, with settlements occurring through connected payment rails rather than a unified currency unit.

How it differs from a common currency:
A common BRICS currency, earlier floated and later abandoned, would have required shared monetary policy frameworks, governance mechanisms, and agreement on issuance—politically and economically difficult given divergent macroeconomic conditions. In contrast, CBDC linkage is a technical and institutional coordination exercise, not a monetary union. It enables faster, cheaper settlements while allowing each central bank to control issuance, regulation, and monetary policy independently.

Relevance in practice:
The proposal builds on the 2025 BRICS declaration in Rio de Janeiro that emphasised payment system interoperability. Similar models exist globally, such as the mBridge project involving China, UAE, and BIS Innovation Hub, which demonstrates that cross-border CBDC linkages can reduce settlement time and costs without undermining sovereignty. Thus, the RBI’s proposal represents a pragmatic, incremental approach to financial cooperation rather than a radical currency overhaul.

Geopolitical context:
The global financial system remains heavily dependent on the U.S. dollar and dollar-dominated infrastructure such as SWIFT. Recent geopolitical tensions, sanctions regimes, and trade wars—particularly involving Russia and China—have heightened concerns among several countries about financial vulnerability. Linking BRICS CBDCs offers an alternative settlement channel that could reduce exposure to dollar-centric systems without explicitly pursuing de-dollarisation.

Strategic implications for BRICS:
For BRICS members, interoperable CBDCs could enhance trade resilience by enabling direct settlements in local currencies. This is especially relevant for energy trade, tourism, and supply-chain financing. While the RBI has clarified that India does not seek de-dollarisation, increased use of the e-rupee in cross-border payments would naturally enhance its international profile. For countries like Russia, which face sanctions-related payment constraints, such systems could be economically significant.

Balancing diplomacy and economics:
The proposal is sensitive geopolitically, as the U.S. has warned against efforts to bypass the dollar, with leaders like Donald Trump calling BRICS “anti-American.” India’s cautious framing—emphasising efficiency, cost reduction, and financial innovation rather than ideological opposition—reflects its broader foreign policy approach of strategic autonomy. Thus, the importance lies not only in payments efficiency but also in shaping a more multipolar financial architecture without provoking direct confrontation.

Operational design:
A linked BRICS CBDC system would require interoperable technological platforms that allow seamless exchange between national digital currencies. Transactions—such as trade invoices or tourism payments—could be settled instantly or periodically through agreed protocols. Weekly or monthly net settlements could reduce liquidity pressures, as suggested by the exploration of bilateral foreign exchange swap arrangements between central banks.

Institutional and regulatory requirements:
Key requirements include common technical standards, cybersecurity protocols, and governance rules on data sharing, dispute resolution, and compliance with anti-money laundering (AML) norms. Trust deficits may arise if countries are hesitant to adopt platforms developed by others, making neutral or jointly governed infrastructure essential. The role of central banks, rather than private entities, ensures regulatory oversight and monetary stability.

Learning from past experiences:
Earlier attempts at rupee–ruble trade settlement illustrate the challenges. Russia accumulated large rupee balances with limited avenues for use, forcing India to allow investment in domestic bonds. A CBDC-linked system, combined with swap lines, could address such imbalances more systematically. Therefore, functionality depends not only on technology but also on macroeconomic coordination and trust among BRICS members.

Potential benefits:
For India, linked CBDCs could lower transaction costs, reduce settlement times, and improve transparency in cross-border payments. It could also promote the international use of the e-rupee in a controlled, regulated manner. Compared to private stablecoins, CBDCs offer stronger safeguards for monetary sovereignty, consumer protection, and systemic stability, as highlighted by RBI Deputy Governor T. Rabi Sankar.

Risks and concerns:
However, risks remain. Increased cross-border use of CBDCs could complicate capital flow management and exchange rate stability if not carefully designed. Technological vulnerabilities, cyber risks, and uneven adoption among BRICS members could undermine effectiveness. Additionally, geopolitical backlash—such as trade or financial retaliation—cannot be ruled out, especially if the initiative is perceived as bypassing the dollar system.

Balanced assessment:
Overall, the proposal’s incremental and interoperability-focused design mitigates many risks associated with radical monetary integration. India’s emphasis on regulation, pilot-based learning, and limited scope reduces systemic threats. The challenge lies in ensuring that innovation does not outpace regulatory capacity, making gradualism and consensus essential for long-term success.

India’s e-rupee experience:
India’s CBDC pilots have focused on practical use cases such as offline payments, programmability for government subsidies, and fintech-enabled wallets. These experiments show that adoption depends on ease of use, trust, and clear value addition over existing systems like UPI. This lesson is crucial for BRICS, where CBDC linkage must demonstrably outperform traditional correspondent banking.

Lessons from local-currency trade:
The rupee–ruble trade arrangement revealed structural challenges, particularly trade imbalances leading to unusable currency surpluses. Allowing investment of surplus rupees in Indian bonds was a stopgap solution. For BRICS CBDCs, mechanisms such as swap lines and periodic settlements must be built in from the outset to manage asymmetries in trade flows.

Broader takeaway:
The key lesson is that technology alone cannot resolve macroeconomic mismatches. Successful CBDC linkage requires alignment of trade structures, financial markets, and regulatory trust. India’s cautious, pilot-driven approach provides a template: scale gradually, address imbalances institutionally, and ensure that digital innovation reinforces—not destabilises—economic fundamentals.
