Former NITI Aayog vice-chairman Rajiv Kumar has urged the government to keep UPI merchant payments free for a few more years, warning that the introduction of even a modest charge could reverse hard-won gains in India's digital payments ecosystem. Speaking in the context of the government's decision to levy a 0.4% merchant discount rate, or MDR, on UPI merchant payments above Rs 2,000 from October 15, Kumar said the policy risks nudging users and merchants back toward cash if transaction costs begin to bite.
The warning lands at a sensitive moment for India's payments architecture. UPI has become the country's most visible digital public infrastructure success, powering everything from small retail purchases to mobility and transport payments. Its appeal has rested on a simple proposition: instant, low-friction transfers with no direct charge to consumers. That model helped UPI move from a convenience tool for urban users into a mass-market payment rail used by street vendors, small businesses, ride-hailing users and EV charging operators alike.
Fee Shock Risk
Kumar's concern is not merely about the fee itself, but about the behavioural response it could trigger across the merchant ecosystem. In payments, even a small cost can alter acceptance decisions, especially among micro and small merchants operating on thin margins. If merchants begin passing on charges, discouraging UPI acceptance, or preferring cash for smaller-ticket transactions, the broader digital transition could slow. That would be particularly consequential in sectors such as automotive retail, EV charging, fuel-adjacent services and mobility platforms, where digital settlement has become increasingly routine.
The government's move appears designed to balance two competing objectives: preserving the consumer-facing free-to-use character of UPI while creating a revenue mechanism for merchant transactions above a threshold. Supporters of MDR argue that payment networks require sustainable economics and that merchant fees are standard across card-based systems. But critics say UPI's scale and public utility status justify continued subsidy, at least until adoption deepens further and the ecosystem can absorb costs without distorting usage patterns.
Kumar's intervention also reflects a broader policy debate over whether India should treat UPI as a public utility akin to digital infrastructure, or as a commercial payments rail that must eventually recover costs from merchants. The answer matters because UPI's growth has not only improved convenience; it has also supported formalisation, traceability and lower cash handling costs across the economy. A fee, however small, could slow that shift at the margins and complicate the government's own push for a less-cash economy.
Policy Trade-Offs
The immediate question is how the new MDR will be implemented in practice and whether it will remain limited to larger merchant transactions. The threshold of Rs 2,000 suggests an attempt to protect small-value everyday payments, but the line between small and medium transactions is blurred in many retail categories. In mobility and auto-related use cases, where ticket sizes can vary widely, merchants may reassess acceptance costs quickly if the fee becomes material.
For the government, the challenge is to avoid a policy signal that undermines trust in UPI's zero-cost consumer promise. That promise has been central to adoption, especially among first-time digital users and small merchants who migrated from cash because UPI was simpler and cheaper than cards or wallet-based alternatives. Any perception that the system is becoming expensive or uncertain could slow transaction growth, even if only temporarily.
Kumar's call to keep UPI merchant payments free for a few more years is therefore less about resisting monetisation altogether and more about sequencing. His argument is that India should protect the network effects already built into UPI before introducing charges that may be easy to impose but harder to reverse. In a payments market where user habits are sticky and cash remains deeply embedded, that caution may prove politically and economically significant.
Cash Versus Convenience
The deeper issue is not whether UPI can survive a fee, but whether the fee changes the incentives that made it successful in the first place. India's digital payments story has been built on convenience, trust and near-zero friction. If those conditions weaken, even slightly, cash retains a structural advantage in many low-value, high-frequency transactions. That is why Kumar's warning resonates beyond the payments sector: it speaks to the fragility of digital adoption when policy shifts alter the economics of everyday use.
As the October 15 deadline approaches, attention will now turn to how banks, payment apps, merchants and regulators interpret the new MDR framework. If the charge is absorbed quietly, the impact may be limited. If it is passed on visibly, the government may face renewed pressure to revisit the policy before it dents one of India's most successful digital public platforms.
