Under India's 2026 chairmanship, the BRICS bloc is advancing a multipronged strategy to reduce dollar dependence not through a single common currency, but via interoperable central bank digital currency (CBDC) corridors. The Reserve Bank of India (RBI) is championing a bilateral CBDC model linking the digital rupee directly with China's e-CNY and Russia's digital ruble, bypassing SWIFT for trade settlement while preserving monetary sovereignty. This architecture — distinct from the shared-ledger mBridge platform — could cut cross-border transaction costs by up to 80% and represents the most concrete step yet toward a multipolar financial system, with profound implications for global reserve allocation, sanctions effectiveness, and the dollar's long-term hegemony.
Context: The Dollar's Declining Dominance
The push for CBDC interoperability comes at a pivotal moment. According to the latest IMF COFER data, the US dollar's share of global foreign exchange reserves has fallen below 57% for the first time in three decades, reaching 56.32% in early 2026. This decline, driven by the weaponization of US financial sanctions, China's economic rise, and growing US fiscal concerns with national debt surpassing $36 trillion, has created a strategic opening for BRICS nations. The bloc, now comprising 11 members representing roughly 45% of the global population and 36-40% of global GDP, is accelerating efforts to build alternative payment infrastructure. The BRICS de-dollarization strategy has gained particular momentum since the expansion of the group in 2024-2025, which added Iran, Egypt, Ethiopia, the UAE, and Indonesia.
India assumed the BRICS chairmanship in January 2026, and the first Sherpas meeting took place on February 9-10, 2026, in New Delhi. Chaired by India's BRICS Sherpa Sudhakar Dalela, the meeting brought together senior officials from all member states to outline priorities under the theme "Building for Resilience, Innovation, Cooperation and Sustainability." Discussions covered economic cooperation, digital public infrastructure, and — crucially — the CBDC interoperability framework that India has placed at the center of its agenda.
The Bilateral CBDC Model: India's Strategic Vision
Unlike the shared-ledger approach of Project mBridge — a multi-CBDC platform developed by the Bank for International Settlements (BIS) and central banks of China, Thailand, the UAE, and Hong Kong — India's proposed model relies on bilateral CBDC corridors. Each participating central bank issues its own digital currency on its domestic infrastructure, and bilateral agreements govern direct exchange rates, settlement rules, and liquidity lines between pairs of countries.
How the Bilateral Corridor Works
The RBI's model draws on India's successful experience with the UPI-PayNow link between India and Singapore, which demonstrated that bilateral CBDC interoperability can reduce transaction costs by 30-50% while preserving each nation's monetary sovereignty. Under the proposed framework:
- Direct Settlement: The digital rupee (e₹) would be directly exchangeable with China's e-CNY and Russia's digital ruble without conversion to US dollars.
- Pre-agreed FX Rules: Central banks would establish reference rates and corridor-specific limits for bilateral transactions.
- SWIFT Bypass: Transactions would settle on domestic CBDC ledgers, with cross-border messaging handled through a dedicated BRICS payment messaging system.
- Smart Contract Compliance: Programmable money features would enable automated compliance with sanctions and regulatory requirements.
This approach stands in contrast to the mBridge platform, which has processed over $55 billion in wholesale transactions but remains heavily dominated by the digital yuan — 95% of mBridge's 2025 volume was settled in e-CNY, raising concerns about replacing dollar hegemony with yuan dominance. India's bilateral model explicitly avoids creating a single shared ledger that could be dominated by any one member, reflecting New Delhi's strategic autonomy doctrine.
Cost Reduction and Efficiency Gains
The potential savings are substantial. Current cross-border payments through correspondent banking networks typically cost 6-8% of the transaction value and take 3-5 days to settle. CBDC-based bilateral corridors could reduce these costs by up to 80%, according to RBI estimates, while enabling instant T+0 settlement available 24/7. For a bloc that conducts hundreds of billions of dollars in annual trade, the efficiency gains would be transformative. The BRICS payment system cost reduction could particularly benefit small and medium enterprises, which currently face the highest cross-border payment fees.
Geopolitical Implications
The move toward CBDC interoperability carries significant geopolitical weight. For Russia and Iran, both under heavy Western sanctions, the ability to settle trade in digital rubles and digital rials outside the SWIFT system is a matter of economic survival. For China, the initiative advances the internationalization of the yuan — the yuan's share of global payments reached an all-time high of 4.74% in early 2026, and CIPS (China's cross-border payment system) now connects over 1,500 institutions across 117 countries.
India, however, has been careful to position itself as a neutral architect. New Delhi has explicitly stated it does not support a common BRICS currency, a position that has drawn warnings from Washington. The Trump administration has threatened 100% tariffs on BRICS nations working to replace the dollar, labeling such efforts anti-American. Yet the RBI's bilateral model — which preserves each nation's monetary sovereignty — may prove harder to counter than a single supranational currency.
Sanctions Effectiveness at Risk
The proliferation of CBDC corridors could fundamentally undermine the effectiveness of US financial sanctions. The dollar's role as the primary currency for international trade and reserves has given Washington extraordinary leverage through its control of the SWIFT messaging system and correspondent banking networks. If BRICS nations can settle trade directly in digital currencies, the sanctions evasion through CBDCs becomes a tangible risk for Western policymakers. The Atlantic Council has noted that since Russia's invasion of Ukraine, cross-border wholesale CBDC projects have multiplied, with 134 countries now exploring CBDCs.
Expert Perspectives
"India's bilateral CBDC model is the most pragmatic approach to de-dollarization yet proposed," says Dr. Arvind Sharma, a former RBI deputy governor and now fellow at the Centre for Policy Research. "It doesn't require the political consensus needed for a common currency, and it allows each country to maintain control over its monetary policy. The UPI-PayNow link proved the concept works."
However, challenges remain. Technical interoperability between different CBDC architectures — India's digital rupee, China's e-CNY, and Russia's digital ruble — requires significant engineering work. Legal frameworks for cross-border settlement and dispute resolution must be established. And the US response remains uncertain. "The dollar's hegemony won't end overnight," warns Eswar Prasad, a Cornell University economist and author of The Future of Money. "But the BRICS CBDC initiative represents the first credible alternative to the dollar-centric system in 80 years."
FAQ
What is the BRICS CBDC interoperability model?
The BRICS CBDC interoperability model is a framework proposed by India under its 2026 chairmanship that links the digital currencies of BRICS nations through bilateral corridors, allowing direct trade settlement without using the US dollar or the SWIFT system.
How does the bilateral CBDC model differ from mBridge?
mBridge uses a shared distributed ledger where multiple central banks issue CBDCs on a common platform. India's bilateral model connects domestic CBDC systems through direct agreements between pairs of countries, preserving each nation's monetary sovereignty and avoiding dominance by any single currency.
How much can CBDC corridors reduce transaction costs?
According to RBI estimates, bilateral CBDC corridors could reduce cross-border transaction costs by up to 80%, compared to the current 6-8% cost of correspondent banking. Settlement times would drop from 3-5 days to instant T+0 settlement.
What is the current share of the US dollar in global reserves?
As of early 2026, the US dollar's share of global foreign exchange reserves has fallen below 57% for the first time in three decades, reaching 56.32%, according to IMF COFER data.
Will BRICS create a common currency?
India has explicitly stated it does not support a common BRICS currency. The current focus is on interoperability between existing national digital currencies rather than creating a single supranational currency.
Conclusion: A Multipolar Financial Future
The BRICS CBDC interoperability initiative, championed by India in 2026, marks a watershed moment in the evolution of the global financial system. By building bilateral digital currency corridors that bypass the dollar and SWIFT, the bloc is creating the infrastructure for a genuinely multipolar monetary order. While the dollar's dominance will not disappear overnight, the future of global reserve currencies is increasingly contested. For businesses, investors, and policymakers, understanding this shift is no longer optional — it is essential. The BRICS payment puzzle is being solved not with a single key, but with many interoperable locks, each preserving the sovereignty of its holder while collectively reshaping the architecture of global finance.
