Former NITI Aayog vice-chairman Rajiv Kumar has cautioned that even a modest fee on UPI merchant payments could undermine one of India's most successful digital public infrastructure platforms and nudge users back toward cash. Speaking in the context of the government's decision to impose a 0.4% merchant discount rate, or MDR, on UPI transactions above Rs 2,000 from October 15, Kumar argued that the policy risks reversing years of behavioural change that helped make digital payments routine for millions of Indians.
Cashless Momentum At Risk
Kumar's warning goes to the heart of a larger policy debate: whether UPI should remain a zero-cost utility for merchants and consumers, or whether the system can absorb limited pricing without denting adoption. UPI has become the backbone of India's retail digital payments ecosystem, powering everything from small neighbourhood purchases to large merchant transactions. Its rapid rise has been driven not only by convenience and speed, but also by the absence of direct charges for users.
The government's latest move preserves that consumer-side free model, but introduces a merchant fee on higher-value transactions. Officials have framed the step as a calibrated measure, not a broad rollback of UPI's free access. Yet Kumar's intervention reflects a concern widely shared by digital payments advocates: once a fee enters the system, even selectively, merchants may begin to alter acceptance behaviour, pass costs on to customers, or encourage cash for certain transactions.
That possibility matters because India's payments transformation has been built on thin margins and high-frequency use. For small retailers, street vendors and service providers, the economics of accepting digital payments can be sensitive to even fractional costs. If merchants perceive UPI as less attractive than cash for larger bills, the system's network effect could weaken, especially in price-sensitive segments where adoption is still maturing.
Policy Trade-Offs Deepen
The government's decision reflects a familiar policy trade-off: sustaining a mass-scale digital payments rail requires funding, but introducing charges can slow usage. The MDR has long been a contentious issue in India's payments market, where policymakers have repeatedly prioritised scale and inclusion over monetisation. By keeping consumer payments free while charging merchants above a threshold, the government appears to be trying to preserve the public-facing appeal of UPI while creating a revenue stream for payment intermediaries.
Still, the design of the fee will be closely watched. The threshold of Rs 2,000 means the charge is aimed at relatively larger merchant transactions, but in practice that may still cover a broad swathe of everyday commerce, including restaurants, electronics, fuel, travel and other retail categories. If merchants begin to split bills, steer customers toward alternate payment modes, or discourage UPI for higher-value purchases, the policy could produce unintended distortions.
Kumar's comments also arrive at a sensitive moment for India's digital economy. UPI is not merely a payments app; it is a public infrastructure layer that has helped formalise commerce, improve transaction traceability and reduce dependence on physical currency. Any policy that appears to make digital payments less frictionless is likely to draw scrutiny from fintech firms, merchants and consumer groups alike.
What Comes Next
For now, the government has signalled that consumer convenience remains protected. But the broader question is whether merchant charges, however limited, can coexist with UPI's core promise of universal, low-friction access. Kumar's warning suggests that the answer may depend less on the size of the fee than on the behavioural signal it sends.
If merchants begin to treat UPI as a paid service rather than a default payment rail, India could see a partial reversion to cash in segments where digital adoption is still fragile. That would be a setback not only for payments policy, but also for the wider push toward a more transparent and efficient retail economy.
The debate now is likely to intensify as the October 15 implementation date approaches. For policymakers, the challenge will be to balance sustainability with scale without eroding the trust and convenience that made UPI a national success story in the first place.
