A cross-border payment is useful when the recipient can use the money, not merely when two systems exchange a message. That distinction provides a practical test for India's reported push to connect central bank digital currencies across BRICS. The relevant question is who makes the service work when currencies, institutions and legal responsibilities differ. A diplomatic objective cannot answer that operating question by itself.
Reuters reported on September 10, citing people familiar with the discussions, that India was promoting such links despite technical and political hurdles. Bloomberg reporting carried by ThePrint independently described the push. This analysis examines that reported proposal; it does not treat it as evidence of an operational bloc-wide network or announce an outcome from the September summit.
A shared rulebook has an economic job
A payment arrangement needs more than compatible software. Participants must know who can join, who operates shared components and who takes responsibility when something fails. These decisions can sound administrative, but they determine whether a customer can rely on the service and whether a financial institution can price the risks it accepts.
The BIS Committee on Payments and Market Infrastructures' framework identifies legal setup, ownership, operational structure and oversight as central questions for linking fast-payment systems. That framework concerns payment-system interlinking generally. It is not a description of an agreed BRICS CBDC design, and using it as an analytical comparator should not imply that BRICS has adopted it.
Consider an unsuccessful transfer. A sender needs to know whether money was debited, whether the recipient received it and who resolves a discrepancy. An operator needs a process for communicating failures and assigning responsibility. The details will depend on the actual scheme. The economic point is that unreliable exception handling can impose time and reconciliation costs even if normal transfers are fast.
Adding countries makes these questions more consequential. A bilateral arrangement can align two sets of institutions around a defined corridor. A broader arrangement must accommodate more participants and differences without making every new connection an entirely bespoke project. Shared rules could reduce that duplication, but negotiating them is itself work. The announcement of an intention to connect does not establish that this work has been completed.
A fast message still needs a usable exchange rate
When sender and recipient use different currencies, someone must supply conversion. The BIS Nexus documentation on foreign-exchange providers makes that role explicit: providers offer exchange rates for cross-currency payments. Nexus is a separate initiative, used here to illustrate the economic function, not as proof of the architecture selected for BRICS.
The implication is that faster communication cannot, by itself, determine the price of exchanging money. A provider needs the ability and willingness to deliver the destination currency on the offered terms. If conversion is expensive or capacity is limited, an efficient technical connection may still leave the end user with an unattractive payment. The size of any saving would require actual prices and service data.
Total cost also includes more than the most visible fee. A customer would need to compare the amount paid with the amount ultimately usable by the recipient, together with the time and uncertainty involved. A low advertised transfer charge would not establish a low overall cost if other parts of the conversion are unfavorable. This is a comparison framework, not a claim about the fees of an unlaunched BRICS service.
For banks and payment companies, that creates both opportunity and uncertainty. A reliable connection could reduce some manual work or support additional transactions. Competition could also change the revenue earned on existing payment services. Whether volumes compensate for different margins depends on adoption, pricing and operating costs. It would be premature to assign a winner from the existence of a proposal alone.
A working corridor is a better test than a universal promise
There is a concrete historical reason not to dismiss payment linking as merely rhetorical. Singapore and India launched the PayNow-UPI linkage in February 2023, documented in the Singapore prime minister's official remarks. That was a link between retail payment systems. It was not a BRICS-wide CBDC network, so the precedent demonstrates a narrower kind of implementation.
The strongest positive interpretation is that practical corridors can create value before every country or use case is included. A limited service with clear responsibilities and useful conversion could be more meaningful to customers than an ambitious design without demonstrated transactions. That possibility does not establish a timetable, but it gives the proposal a testable route from policy language to economic usefulness.
Evidence that would strengthen the case includes identified participants, published operating responsibilities and documented end-to-end transfers with transparent costs. Evidence of repeated failures, unclear liability or little customer use would weaken it. Those measures address the service delivered rather than the symbolism of the currency used.
The reported initiative is therefore best assessed as an infrastructure proposition. Its value would come from reliable execution at a useful cost, under rules participants can actually operate. A faster payment corridor could be worthwhile without proving a transformation of the global monetary system. That is a sufficiently demanding goal, and one that can eventually be measured.
