An IIT Bombay report has raised a pointed warning over the proposed merchant discount rate, or MDR, framework for Unified Payments Interface transactions, saying the plan could undermine public trust if rolled out without meaningful recalibration. The assessment comes at a sensitive moment for India's digital payments ecosystem, where UPI has become not just a convenience tool but a public utility-like layer of everyday commerce.
The report's central concern is not merely the mechanics of pricing, but the broader behavioural risk of altering the perception of UPI among users and merchants. By cautioning that the platform could attract negative sentiment in its present form, the study underscores a political and economic reality: UPI's success has rested heavily on the belief that digital payments are simple, low-friction and broadly cost-free at the point of use. Any policy change that appears to shift costs onto merchants, and potentially consumers, risks unsettling that trust.
Trust At Stake
UPI has grown into the backbone of India's retail digital payments system, powering transactions across urban and semi-urban markets, small businesses, transport services and a growing share of mobility-related payments. In sectors such as automotive retail, EV charging, ride-hailing and daily commuting, the platform has become embedded in the transaction chain. That makes any discussion around MDR especially consequential, because even a modest change in fee structures can ripple across merchant behaviour, pricing decisions and consumer sentiment.
The IIT Bombay report appears to be arguing that the policy debate should not be reduced to a narrow question of revenue recovery for payment intermediaries. Instead, it should be framed around the sustainability of the digital payments ecosystem as a whole. If merchants begin to view UPI as a cost centre rather than a low-cost acceptance channel, they may pass on charges indirectly, discourage digital payments, or steer customers toward alternatives. Such outcomes would run counter to the government's long-standing push for cashless adoption.
Policy Design Matters
The warning is particularly relevant because UPI's public legitimacy has been built over years of policy support, interoperability and user familiarity. Unlike card networks, where MDR has long been an accepted part of the payments model, UPI has been positioned as a mass-market public digital rail. Introducing or expanding MDR without a carefully communicated framework could therefore create confusion about whether the platform remains free, subsidised, or selectively monetised.
That ambiguity matters in India, where digital payment behaviour is highly sensitive to trust, incentives and ease of use. The report's emphasis on rationalisation suggests that any MDR framework must be designed with clear thresholds, transparent cost allocation and safeguards for small merchants and high-frequency low-value transactions. Without such guardrails, the policy could be perceived as penalising the very businesses that helped normalise UPI at scale.
For the mobility sector, the implications are practical as well as reputational. EV charging operators, fleet services, auto dealers and transport aggregators increasingly rely on instant digital settlement. If transaction costs rise or user confidence weakens, the friction could slow adoption in segments that depend on seamless, high-volume payments. In a market where convenience is a competitive advantage, even small disruptions can alter consumer behaviour.
Wider Digital Signal
The report also arrives amid a broader policy conversation about how India should fund and sustain its digital public infrastructure. UPI's expansion has been extraordinary, but scale has not eliminated the question of who pays for the system's operating costs. The challenge for policymakers is to preserve the platform's public-good character while ensuring that payment providers, banks and merchants remain economically viable.
That balance is delicate. A framework that is too aggressive could weaken adoption and invite backlash. One that is too cautious may leave the ecosystem financially strained and dependent on continued state support. The IIT Bombay report, by warning against negative sentiment, appears to be urging a middle path: one that protects the user experience, preserves merchant participation and avoids turning a national success story into a contested fee debate.
For now, the message is clear. UPI's strength lies not only in technology, but in trust. Any MDR framework that fails to account for that could prove costly well beyond the payments sector.
