An IIT Bombay report has sounded a cautionary note on the future of India's Unified Payments Interface, warning that the proposed merchant discount rate framework could damage public confidence if introduced without careful rationalisation. The report argues that UPI's success has been built not only on convenience and scale, but also on the perception that it is a low-friction, low-cost public digital utility. Any policy shift that alters that perception, it says, risks triggering negative sentiment among users and merchants alike.
The warning comes at a sensitive moment for India's digital payments ecosystem. UPI has become the backbone of everyday transactions across retail, transport, mobility services and a growing share of consumer spending. Its rapid adoption has been underpinned by the absence of direct charges for most users, creating a strong behavioural habit around instant, app-based payments. The IIT Bombay assessment suggests that this trust premium is itself a policy asset, and one that could be weakened if the MDR framework is seen as a backdoor cost burden on the public.
Trust At Stake
The report's central concern is not merely the level of fees, but the signal such fees send. In a system that has been promoted as inclusive and frictionless, even a modest perception of monetisation can alter user behaviour. That matters because payment systems are highly sensitive to sentiment: once consumers begin to associate a platform with extra charges, reduced convenience or merchant resistance, adoption can slow even if the underlying technology remains robust.
For the mobility and automotive ecosystem, the implications are significant. UPI is now deeply embedded in ride-hailing, parking, toll-linked services, EV charging, dealership payments and other mobility-related transactions. These use cases depend on speed, low cost and trust at the point of sale. If merchants begin passing on costs or if users perceive that digital payments are becoming more expensive, the friction could ripple through sectors that have come to rely on UPI for seamless transactions.
The report therefore calls for a rationalised framework that balances sustainability for payment infrastructure with the preservation of public trust. That balance is crucial because India's digital payments architecture has been built through a combination of public policy support, private innovation and broad consumer acceptance. A poorly calibrated MDR regime could upset that equilibrium by making the system appear less like a public utility and more like a fee-bearing commercial product.
Policy Balance Needed
At the heart of the debate is how to fund the cost of running a payment network at massive scale. Transaction processing, fraud management, customer support and platform maintenance all carry real costs. Yet the policy challenge is to recover those costs without undermining the very adoption that makes the network valuable. The IIT Bombay report appears to argue that the present form of the proposed MDR framework does not yet strike that balance convincingly.
This is especially relevant in a country where digital payments are still expanding into smaller towns, informal commerce and lower-value transactions. In those segments, even small charges can influence whether merchants accept digital payments and whether consumers choose them over cash. The report's warning suggests that the government and regulators must be careful not to introduce a structure that could slow financial inclusion or revive cash preference in price-sensitive markets.
The broader policy lesson is that UPI's strength lies in its public trust quotient. Once users begin to suspect that the platform is becoming costly, opaque or unevenly priced, the reputational damage can be difficult to reverse. That is why the report's emphasis on rationalisation is significant: it is not rejecting the idea of cost recovery, but insisting that any framework must be designed to protect confidence in the system.
For India's digital economy, the stakes extend beyond payments alone. UPI has become a foundational layer for commerce, mobility and emerging EV-related services. If trust in that layer weakens, the effects could spread across the wider ecosystem. The IIT Bombay report therefore places a clear marker before policymakers: preserve the public character of UPI, or risk turning a national digital success story into a source of consumer unease.
