TL;DR
- BRICS bloc countries are exploring ways to link their instant payment systems and CBDCs to reduce costs in cross-border transactions.
- The Governor of the Reserve Bank of India noted that talks are still preliminary and no agreed architecture or timeline exists.
- Trade imbalances and technical differences among members represent concrete obstacles that no payment system can resolve on its own.
The BRICS bloc countries are advancing talks to link their instant payment systems and their CBDCs with the goal of reducing costs in international transactions.
The Governor of the Reserve Bank of India, Sanjay Malhotra, confirmed that bloc members are discussing connections between their national payment networks and their digital currencies. The talks do not address a defined architecture or implementation timeline, but India, host of the 2026 BRICS summit, had already indicated this week that CBDC interoperability would feature on the official agenda.
The central argument is the reduction of intermediaries. If national systems can communicate directly, more commercial operations could be settled without going through traditional channels, which would theoretically reduce time and costs. What is not stated with sufficient clarity is the price citizens pay in terms of state control over every transaction they carry out with a CBDC.
CBDCs as a Control Mechanism, not Efficiency
The technical discussion conceals a deeper problem: a CBDC is not simply a faster payment method, but an instrument that grants governments the ability to track, block, or condition every movement of their citizens’ money. The proposal to interconnect these tools among five states with varying authoritarian track records does not expand financial freedom — it restricts it in a coordinated and cross-border manner.
The differing levels of CBDC development among members illustrate how far that logic can reach. China leads with the digital yuan, which has already processed 3.48 billion cumulative transactions worth $2.47 trillion through the end of November 2025. Russia requires its major banks to offer digital ruble services starting September 1, 2026. India is running a pilot of the e-rupee alongside UPI, which recorded 23.66 billion transactions in July 2026. Brazil is exploring international connections for Pix. South Africa maintains a cautious stance in the retail market.
Faster Settlement, Deeper Problems
Settlement speed does not resolve trade imbalances. India and Russia already faced that reality: trade in local currencies left Russia accumulating rupee balances that were difficult to recycle.
A recent experiment by the Bank of Italy also found that the highest costs in cross-border transfers appear when entering or exiting the digital system, not during the transfer itself. Any common architecture would require shared rules on settlement finality, regulatory compliance, privacy, and liquidity management. Solving the technical side does not guarantee that economic and legal agreements will work, especially among countries with markedly different technologies, regulations, and trade relationships.
