Trust at Stake
An IIT Bombay report has warned that the proposed merchant discount rate, or MDR, framework for Unified Payments Interface transactions needs rationalisation to avoid undermining public trust in India's most widely used digital payments rail. The report argues that UPI's success has been built not only on speed and convenience, but also on the public perception that it is simple, dependable and largely free at the point of use. Any policy shift that unsettles that perception, it said, could trigger negative sentiment among users and weaken the platform's social acceptance.
The caution comes at a sensitive moment for India's digital payments ecosystem, which has become central to everyday commerce, mobility services and the broader consumer economy. From fuel stations and vehicle servicing to ride-hailing, EV charging and small retail purchases, UPI has become the default transaction layer for millions of users. In sectors such as automotive and mobility, where high-frequency, low-value payments are common, even modest changes in transaction economics can have outsized behavioural effects.
The report's core concern is not simply the existence of MDR as a policy instrument, but the risk that an ill-calibrated framework could be interpreted by consumers as the beginning of a broader cost burden on digital payments. That, in turn, could slow adoption, encourage cash reversion in some segments and create confusion around who ultimately bears the charge. The study stresses that policy design must protect the credibility of UPI as a public digital utility while still addressing the commercial realities faced by payment intermediaries and merchants.
Policy Balance Needed
MDR has long been a contested issue in India's payments landscape because it sits at the intersection of merchant economics, bank incentives, payment processor viability and consumer expectations. A rationalised framework, the report suggests, would need to distinguish between merchant categories, transaction values and use cases rather than applying a blunt, one-size-fits-all approach. Such differentiation could help prevent unnecessary friction in sectors where digital acceptance has only recently become mainstream.
For the mobility and automotive ecosystem, the implications are especially significant. EV charging networks, service centres, spare parts outlets and fleet operators increasingly rely on UPI for quick settlement. If merchants perceive the framework as expensive or operationally complex, they may pass costs through indirectly, reduce digital acceptance, or push for alternative payment methods. That would run counter to the government's broader push for digitisation and formalisation of commerce.
The report also implicitly raises a communication challenge for policymakers. In India's payments market, public trust is not a soft variable; it is a structural asset. UPI's rapid rise has depended on a clear user proposition: instant transfers, broad acceptance and minimal visible cost. If the policy debate around MDR is not explained carefully, users may conflate merchant charges with consumer charges, even where the direct burden does not fall on them. That perception alone could be enough to alter behaviour.
UPI's Public Utility Role
The broader policy question is how to sustain the economics of digital payments without diluting the public-good character of UPI. The IIT Bombay report appears to argue that the answer lies in calibration, not abrupt monetisation. That means preserving incentives for banks and payment firms, protecting small merchants from disproportionate costs and ensuring that consumers do not develop the impression that UPI is becoming a premium service.
This debate also arrives as India continues to expand digital infrastructure across transport, mobility and consumer services. The more deeply UPI is embedded into daily life, the more sensitive it becomes to any policy signal that could be read as a retreat from the zero-friction model that drove adoption. For that reason, the report's warning is as much about sentiment management as it is about pricing architecture.
In effect, the study is urging policymakers to treat UPI not merely as a payments product, but as a trust-based national platform. If the MDR framework is implemented without sufficient nuance, it could create avoidable resistance at a time when India is trying to deepen digital inclusion and sustain momentum in cashless transactions. The report's message is clear: rationalisation is not optional if the goal is to protect confidence in the system and avoid turning a policy adjustment into a reputational setback.
