India’s CBDC Counter-Move: Why the RBI Wants BRICS Nations to Link Digital Currencies

India’s BRICS Chairmanship and the CBDC Agenda

India assumed the rotating BRICS+ chairmanship in January 2026, inheriting a financial cooperation agenda that had gained significant momentum under the previous Brazilian and Russian presidencies. Among the initiatives carried forward was the mBridge wholesale settlement platform, a distributed-ledger system for central bank digital currency (CBDC) transactions—government-issued digital versions of national fiat currencies designed for interbank and cross-border settlement.

However, India’s approach to the CBDC agenda diverges sharply from the trajectory established by mBridge’s early participants. Rather than deepening integration into a single multilateral platform, the Reserve Bank of India (RBI) has proposed a fundamentally different architecture: a network of bilateral CBDC linkages that connect individual sovereign digital currencies without requiring any nation to cede control to a shared ledger or governance framework.

This proposal reflects India’s broader strategic autonomy doctrine—the principle that India should maintain independent decision-making capacity across all dimensions of national policy, including monetary and financial infrastructure. For the RBI, the India CBDC interoperability BRICS 2026 agenda is not merely a technical initiative; it is a statement of sovereign intent in an era when digital currencies are becoming instruments of geopolitical influence.

The mBridge Problem: Platform Dominance and the Yuan Concentration

To understand India’s counter-proposal, it is essential to grasp why mBridge has become a source of concern rather than confidence for most BRICS members. The mBridge platform, originally developed under the auspices of the Bank for International Settlements (BIS) Innovation Hub in collaboration with the People’s Bank of China, the Hong Kong Monetary Authority, the Bank of Thailand, and the Central Bank of the UAE, has processed over $55 billion in wholesale CBDC transactions since reaching Minimum Viable Product status in 2024.

The critical issue is concentration. Approximately 95% of all transactions processed through mBridge have been denominated in the digital yuan (e-CNY). This lopsided usage is a direct consequence of China’s substantial head start in CBDC deployment. The People’s Bank of China began piloting its digital currency in 2020, and by 2026, the e-CNY operates across dozens of Chinese cities with integration into major commercial banks and payment platforms. No other mBridge participant has achieved comparable CBDC readiness.

For India and other BRICS members, this creates an uncomfortable dynamic. The stated purpose of BRICS financial infrastructure is to reduce dependence on any single dominant currency—specifically the US dollar. Yet mBridge, in its current operational reality, risks substituting dollar hegemony with yuan hegemony. A platform where one currency accounts for 95% of transactions is not a multilateral settlement system; it is a Chinese payment rail with peripheral participation from other central banks.

The RBI’s Counter-Proposal: Bilateral Interoperability

The RBI’s alternative vision for India CBDC interoperability BRICS 2026 rejects the monolithic platform model in favor of a network architecture. Under this proposal, each BRICS member would develop and operate its own sovereign CBDC according to domestic requirements and technical preferences. Interoperability (the ability of different digital currency systems to communicate and transact with each other) would be achieved through bilateral linkages—standardized technical bridges connecting pairs of national CBDCs.

This architecture resembles the successful UPI-PayNow linkage between India and Singapore, which connects two distinct domestic payment systems through a bilateral interoperability layer without requiring either country to adopt the other’s platform. Each system retains full sovereignty over its domestic operations, monetary policy, and data governance, while the interoperability layer handles currency conversion, message translation, and settlement confirmation.

The RBI envisions extending this model across the BRICS membership. An India-Brazil CBDC corridor would enable direct rupee-real settlement. An India-UAE corridor would handle rupee-dirham transactions. Each corridor would operate independently, governed by bilateral agreements between the two participating central banks, with shared technical standards ensuring that the corridors can eventually be networked into a mesh.

Critically, no single node in this network would have disproportionate control. Unlike mBridge, where the underlying distributed ledger infrastructure reflects Chinese technological design choices, the bilateral model allows each country to implement interoperability using its preferred technology stack—whether blockchain-based, API-driven, or built on conventional real-time gross settlement (RTGS) architecture.

Strategic Autonomy: India’s Non-Negotiable Doctrine

India’s insistence on bilateral CBDC linkages rather than a shared platform is rooted in its broader strategic autonomy doctrine—a foreign policy framework that predates the current CBDC debate by decades. Since independence, India has consistently sought to avoid dependency on any single external power for critical national capabilities, whether in defense, energy, or technology.

In the financial domain, this doctrine translates into a clear requirement: India must retain sovereign control over its monetary infrastructure. A shared CBDC platform governed by multilateral consensus—or worse, dominated by a single member’s technological choices—violates this requirement. The RBI’s position is that participation in any cross-border digital currency system must be conditional on India’s ability to modify, suspend, or withdraw from the arrangement unilaterally, without disrupting domestic monetary operations.

This stance has gained urgency in the context of escalating US-China technology competition and the use of financial infrastructure as a geopolitical weapon. The 2022 freezing of Russian central bank reserves demonstrated that integration into another power’s financial infrastructure creates latent vulnerability. India’s CBDC strategy is designed to ensure that no equivalent leverage can be exercised over the rupee’s digital incarnation—whether by Washington, Beijing, or any future adversary.

Economic Incentives: Transaction Costs and Settlement Speed

Beyond strategic considerations, the India CBDC interoperability BRICS 2026 proposal carries significant economic benefits. The current correspondent banking system (a network of intermediary banks that facilitate cross-border payments by maintaining accounts with each other across jurisdictions) imposes substantial costs on international transactions. A typical cross-border payment between two BRICS nations may pass through three or four intermediary banks, each adding fees, and may take two to five business days to settle.

The RBI’s target is a 30–50% reduction in cross-border transaction costs through direct CBDC-to-CBDC settlement in local currencies. By eliminating intermediary banks from the settlement chain, bilateral CBDC corridors can compress both cost and time. Real-time settlement—completing both legs of a cross-currency transaction within seconds rather than days—eliminates settlement risk (the possibility that one party delivers currency while the other defaults before completing its side of the trade).

For India, these savings are material. India receives over $125 billion annually in inward remittances, primarily from the Gulf states, the United States, and Southeast Asia. Remittance fees currently average 4–6% of the transaction value through traditional banking channels. Even a modest reduction in these fees through CBDC-based corridors would return billions of dollars annually to Indian workers and their families.

Trade settlement also stands to benefit substantially. India’s bilateral trade with Russia, for example, has been complicated by the absence of direct rupee-ruble settlement infrastructure following the disruption of dollar-based channels. CBDC interoperability corridors could provide the missing plumbing for direct local currency trade settlement, insulating bilateral commerce from USD tariff escalations and currency volatility driven by US monetary policy decisions.

Technical and Institutional Challenges

The bilateral interoperability model is not without significant hurdles. Building individual CBDC corridors between every pair of BRICS+ nations is an enormous technical and diplomatic undertaking. With 10 or more participating countries, the number of bilateral corridors required grows combinatorially—potentially dozens of individual linkages, each requiring negotiated governance rules, shared technical standards, and mechanisms for handling imbalanced trade volumes.

Imbalanced trade is a particularly thorny problem. When two countries trade unevenly—as India and China do, with India running a persistent trade deficit—the surplus country accumulates the deficit country’s digital currency. Without agreed mechanisms for converting or repatriating these balances, surplus accumulation can create pressure on the deficit country’s exchange rate and monetary policy autonomy. The RBI’s proposal must include clearing mechanisms that address these imbalances without requiring either party to hold unwanted foreign digital currency indefinitely.

Institutional hesitation presents perhaps the most significant barrier. Many BRICS central banks remain cautious about adopting foreign technology platforms or exposing their domestic monetary infrastructure to external connections. The digital rupee itself remains in a relatively early pilot phase, with retail and wholesale deployments still limited in scope. Persuading counterpart central banks to invest in bilateral corridors requires demonstrating not just technical feasibility but also sustained political commitment and operational reliability.

Additionally, anti-money laundering (AML) and counter-terrorism financing (CTF) compliance must be embedded into every bilateral corridor. Cross-border CBDC transactions that bypass traditional correspondent banking channels also bypass the compliance infrastructure that those banks provide. Each corridor must include transaction monitoring, sanctions screening, and suspicious activity reporting capabilities—ideally to standards that maintain BRICS members’ relationships with the Financial Action Task Force (FATF) and other international regulatory bodies.

Bilateral Model vs. mBridge: A Structural Comparison

The fundamental tension between India’s bilateral approach and the mBridge monolithic model reflects a deeper philosophical disagreement about the nature of multilateral financial infrastructure. The mBridge model prioritizes efficiency: a single shared ledger reduces integration complexity, enables multilateral netting (offsetting transactions across multiple currency pairs simultaneously), and concentrates technical expertise in one development effort. Its weakness is governance—specifically, the risk that the platform’s design and operation reflect the interests of its most technologically advanced participant.

India’s bilateral model prioritizes sovereignty and resilience. By distributing interoperability across multiple independent corridors, the model ensures that no single point of failure or control can disrupt the entire network. If one bilateral corridor encounters technical problems or political friction, all other corridors continue operating normally. This resilience comes at the cost of complexity: managing dozens of bilateral relationships is inherently more resource-intensive than participating in a single multilateral platform.

In practice, the eventual BRICS CBDC architecture may incorporate elements of both approaches. A hub-and-spoke hybrid—where bilateral corridors handle the majority of settlement but a lightweight multilateral coordination layer provides common messaging standards and dispute resolution—could capture the sovereignty benefits of the bilateral model while achieving some of the efficiency gains of centralized infrastructure. India’s 2026 chairmanship provides the diplomatic window to negotiate this compromise.

Implications for the Global Monetary Order

The outcome of India’s CBDC interoperability push carries implications far beyond the BRICS membership. If India succeeds in establishing a viable network of bilateral CBDC corridors, it will demonstrate that cross-border digital currency settlement does not require submission to any single platform or dominant currency. This proof of concept would be attractive to dozens of non-BRICS emerging economies that share India’s concerns about monetary sovereignty but lack the scale to build independent financial infrastructure.

For the United States and the dollar-based financial system, the India CBDC interoperability BRICS 2026 initiative represents a more subtle challenge than mBridge. A Chinese-dominated platform is easy to characterize as a geopolitical threat and counter with sanctions or diplomatic pressure. A distributed network of bilateral CBDC corridors, each governed by sovereign agreements between independent nations, is far harder to oppose without appearing to challenge the principle of monetary sovereignty itself.

The coming months of India’s BRICS chairmanship will determine whether the bilateral interoperability vision can advance from concept to implementation. Technical working groups, governance framework negotiations, and pilot corridor deployments are all on the 2026 agenda. The RBI’s ability to build consensus among BRICS central banks—many of which have competing interests and varying levels of CBDC readiness—will test India’s diplomatic capacity as much as its technical expertise.
