The National Payments Corporation of India is preparing a significant recalibration of the country's flagship digital payments system, with a proposed 0.4% merchant discount rate on UPI transactions that could recover as much as Rs 15,000 crore a year in operating and infrastructure costs. The move, if adopted, would mark the most consequential shift in UPI's economics since the platform was made free for most users and merchants, and would reopen a debate over who should bear the cost of India's fastest-growing payments rail.
NPCI chief executive Dilip Asbe said the proposal is designed to address a widening funding gap after six years of zero MDR, or merchant discount rate, on UPI payments. According to Asbe, the network's investment cycle has slowed because the current model leaves limited room to finance upgrades, capacity expansion and product development at the scale required by India's digital commerce boom. He argued that a modest fee on selected merchant transactions would help sustain the system without undermining the broad consumer adoption that has made UPI central to everyday payments.
Merchant Fee Reset
The proposed 0.4% charge would not apply uniformly across the ecosystem. Asbe said about 80% of the expected MDR collection would come from large businesses that already accept credit cards, suggesting the burden would fall primarily on merchants with established digital payment infrastructure and stronger ability to absorb transaction costs. That design is politically and commercially important: by concentrating the fee on larger merchants, NPCI appears to be trying to preserve the zero-cost experience for smaller businesses and ordinary users who have driven UPI's mass adoption.
The structure also reflects a broader policy balancing act. India's payments architecture has been built on the premise that low-cost digital transfers can accelerate formalisation, reduce cash dependence and widen financial inclusion. Yet the operating costs of maintaining a national-scale instant payments network are rising as transaction volumes surge. A fee on merchants, rather than consumers, would preserve the public-facing promise of free UPI while creating a revenue stream to support the system behind the scenes.
Costs Behind Free UPI
UPI has become one of India's most important financial infrastructure platforms, processing billions of transactions each month and reshaping retail payments across urban and semi-urban markets. Its success, however, has also created a structural challenge: the network's scale has increased sharply, but the economics supporting it have not kept pace. With no MDR on most UPI payments, the cost of running the system has largely been absorbed through policy support and ecosystem incentives rather than direct transaction revenue.
Asbe's comments suggest that NPCI believes this model is no longer sustainable at current volumes and ambitions. The organisation is seeking to recover annual costs estimated at Rs 13,000-15,000 crore, a figure that underscores the scale of the infrastructure required to keep UPI reliable, secure and interoperable. The proposed fee would therefore be less a commercial surcharge than a funding mechanism for a public digital utility that has outgrown its original subsidy framework.
For merchants, the implications will depend on how the final rules are structured and whether the fee is passed through, absorbed, or offset by lower cash-handling costs and faster settlement benefits. Large retailers and digital-first businesses may be better positioned to adapt, while smaller merchants could remain insulated if the policy continues to exempt low-value or small-ticket transactions.
Policy Trade-Offs Ahead
Any reintroduction of MDR, even in limited form, is likely to attract scrutiny because UPI has been marketed as a zero-cost public good for consumers and merchants alike. The challenge for policymakers will be to preserve the platform's accessibility while ensuring that the network remains financially viable as transaction volumes and security demands rise. A poorly calibrated fee could slow adoption at the margin or revive concerns that digital payments are becoming more expensive for businesses.
At the same time, the proposal may be viewed as a pragmatic response to a maturing payments ecosystem. India's digital payments stack has moved from a phase of rapid expansion to one of operational consolidation, where reliability, fraud prevention, merchant onboarding and product innovation require sustained investment. If NPCI can recover costs without materially affecting consumer usage, the move could strengthen the long-term resilience of UPI rather than weaken it.
The discussion now shifts to how the fee would be implemented, which merchants would be covered, and whether regulators and government stakeholders will endorse a partial return to transaction pricing after years of zero MDR. For now, the signal from NPCI is clear: the era of fully free UPI for the ecosystem may be nearing its economic limits, even if it remains free for most users at the point of payment.
