BRICS Explores Linking CBDCs and Fast-Payment Systems to Cut Cross-Border Costs
Key Takeaways
- •BRICS is exploring connections between national instant-payment systems and CBDCs, but the talks remain preliminary.
- •India has backed adding CBDC interoperability to the agenda for the 2026 BRICS summit it will host.
- •UPI, Pix, and existing bilateral links such as UPI with PayNow and Aani show that some payment interoperability is already technically possible.
- •China is the most advanced on CBDCs, Russia is preparing a wider digital-ruble rollout, and South Africa is taking a more cautious approach.
- •A major obstacle is not just technology but the need for rules on settlement, compliance, liquidity, and handling persistent trade imbalances.

Reserve Bank of India Governor Sanjay Malhotra announced on August 11 that BRICS members are in early-stage discussions about connecting their fast-payment systems and central bank digital currencies (CBDCs). No architecture or launch timeline has been agreed upon. India, which is hosting the 2026 BRICS summit, had previously recommended through the RBI that CBDC interoperability be included on the agenda. The bloc's expanded membership—which now includes the UAE, Egypt, Iran, and Ethiopia alongside the original five—adds further complexity, since newer members bring their own payment infrastructures and, in some cases, sanctions-related constraints.
The driving motivation is practical: cross-border payments remain expensive. Linking national payment systems could reduce the number of intermediaries required to move money across borders and accelerate settlement for trade and tourism. The RBI also seeks to expand the use of local currencies in international transactions, allowing more bilateral trade to be settled without relying on existing channels.
Fast-Payment Rails Alongside CBDCs
India's own infrastructure illustrates why the conversation extends beyond digital currencies. The digital rupee remains in an RBI pilot phase, while the Unified Payments Interface (UPI) already operates at massive scale. According to official NPCI data, UPI processed approximately 23.66 billion transactions worth roughly $313 billion in July 2026 alone.
India has already demonstrated that bilateral fast-payment links are technically feasible. UPI is connected to Singapore's PayNow and the UAE's Aani instant-payment system, giving Indian users the ability to send money abroad via QR-code-based transfers. These existing corridors offer a tested blueprint for what BRICS-scale interoperability might look like, even if they remain limited to specific country pairs.
The two domestic systems already overlap in practice—digital-rupee wallets can scan UPI merchant QR codes, even though the underlying settlement mechanisms differ.
Brazil offers a different model. Its Pix instant-payment network processed nearly 80 billion transactions worth more than 35 trillion reais in 2025, and the Brazilian central bank is now examining links between Pix and foreign instant-payment systems.
This diversity broadens the technical challenge for BRICS. Some members already operate mature instant-payment rails that could be connected internationally, while their CBDCs are progressing on very different timelines.
Divergent CBDC Development Across Members
China is the most advanced. As previously reported, Beijing expanded the e-CNY network in April by authorizing 12 additional commercial banks and advancing its cross-border settlement infrastructure. Official Chinese government data shows that by the end of November 2025, the e-CNY had processed 3.48 billion cumulative transactions worth $2.47 trillion. In 2026, the design was updated so that digital-yuan balances held in authorized commercial-bank wallets can earn interest and are treated as bank deposit liabilities covered by deposit insurance.
China and the UAE, both now BRICS members, also participated in Project mBridge—a multi-CBDC cross-border settlement platform that conducted live transactions involving commercial banks. The Bank for International Settlements withdrew from the project in October 2024, and the participating central banks have continued development independently. The experiment demonstrated that direct CBDC-to-CBDC settlement between central banks is technically possible, though it also surfaced the same governance questions that BRICS now faces.
Russia is moving toward a broad rollout. The Bank of Russia has directed major banks to begin offering digital-ruble services starting September 1, 2026, with large qualifying retailers also required to accept it.
South Africa is proceeding more cautiously. The South African Reserve Bank has stated there is no compelling immediate need to launch a retail CBDC, preferring to focus on broader payment modernization while continuing to study wholesale applications.
Any common BRICS architecture would need to accommodate these differences rather than assume every member is building the same type of digital-payment system.
Settlement Speed and the Dollar Debate
The initiative will inevitably be examined in the context of the broader debate over the U.S. dollar's role in global trade. If an Indian importer and a Brazilian exporter can settle efficiently through linked national systems using rupees and reais, that transaction may reduce reliance on dollar intermediation. Across enough trade corridors, local currencies could gradually play a larger settlement role.
The RBI has emphasized that its efforts to internationalize the rupee are not framed as a formal de-dollarization campaign. The more immediate objective is reducing costs and facilitating local-currency settlement where commercially viable.
Lower transaction costs also depend on factors beyond the payment rail itself. A recent Bank of Italy experiment found that the largest costs in cross-border stablecoin transfers often arose when users entered or exited the digital-asset system, rather than during the underlying transfer.
Trade Imbalances Present a Persistent Challenge
Uneven trade creates a separate and more difficult problem. When the RBI first promoted the CBDC-linking concept earlier this year, Reuters reported that governance, technical standards, regulation, and trade imbalances were among the hurdles officials anticipated.
India and Russia have already encountered this issue in practice. Greater local-currency trade left Russia accumulating rupee balances that proved difficult to recycle efficiently. Accelerating settlement does not resolve the structural problem that arises when one party consistently receives more of another country's currency than it can readily deploy.
Central banks would still need mechanisms for currency conversion, liquidity provision, and managing persistent imbalances between trading partners.
The Challenges Beyond Technical Interoperability
A functional BRICS payment system would require common rules covering settlement finality, compliance, cybersecurity, privacy, and access. It would also need clear frameworks for what occurs after a payment clears: which currency is held, how excess balances are converted, and who provides liquidity when trade flows are uneven.
Technical interoperability can shorten the path between payer and recipient, but the economic and legal arrangements will determine whether the network functions reliably at scale. If BRICS can address both dimensions, member countries would gain practical new options for settling trade directly in national currencies, even as their domestic payment systems and digital-currency projects remain fundamentally different.
The central question is not simply whether BRICS can connect payment rails and CBDCs, but whether it can make the settlement behind those connections work across countries with different technologies, regulatory frameworks, and trade relationships.
