UPI MDR debate: The government has settled one part of the debate over UPI charges. Consumers will continue to use the payment system without paying a transaction fee. What remains unsettled is who will pay for running a network that processed nearly 24 billion transactions in a single month.
The Standing Committee on Finance has put numbers to the problem. The Union Budget 2026-27 has earmarked ₹2,000 crore for RuPay debit cards and low-value BHIM-UPI merchant transactions. The standing committee has warn that the gap between the outlay and the estimated annual operating cost of ₹20,700 crore for the UPI ecosystem could constrain spending on cybersecurity, fraud prevention and payment infrastructure.
The subsidy made sense when the government was trying to persuade consumers and merchants to abandon cash. That job has largely been done. UPI now needs a financing model that does not depend indefinitely on the Union Budget.

UPI MDR could return for larger merchants
The Finance Ministry is considering two approaches. One is to restore the merchant discount rate, or MDR, for some higher-value transactions or larger merchants. The other is to reduce government incentives in stages. No MDR structure, threshold or timetable has yet been finalised.
MDR is paid by a merchant to banks and payment service providers for processing a digital transaction. UPI merchant payments carried an MDR of up to 0.30% before the government introduced zero MDR from January 2020.
Finance Minister Nirmala Sitharaman has said consumers will not bear any UPI charge. That leaves room for a merchant fee without disturbing the feature that helped UPI spread so rapidly: the customer pays nothing.
A uniform merchant charge would still be a poor solution. A small shop accepting low-value payments is in a different position from a large retailer processing substantial volumes through UPI. Charging them on identical terms could undo part of the gain from bringing small merchants into formal digital payments.
A restricted MDR could instead recover some costs from businesses that derive greater commercial value from the network. Large merchants already incur costs for accepting cards and other payment instruments. There is no obvious reason why UPI acceptance by such businesses must remain permanently free.
The risk is that merchants pass the charge on. They could raise prices, steer customers towards another payment method or attempt to recover the fee in other ways. For low-margin businesses, even a small charge matters. The threshold, merchant classification and MDR rate therefore matter more than the abstract argument over whether MDR should return.

Tiered UPI incentives offer another route
The second option deserves greater attention. Government support could be reduced gradually instead of moving directly from zero MDR to a fee-based system.
A tiered incentive can distinguish between transaction values and merchant categories. Subsidies could remain where the government has a clear financial-inclusion objective and decline where UPI has already become commercially entrenched.
This would also give banks and payment companies time to adjust their business models. The exchequer would no longer have to finance the same proportion of an expanding network year after year.
For now, this looks more workable than relying entirely on MDR. It preserves the zero-charge experience for consumers and gives the government more control over where support is withdrawn.

UPI funding cannot remain unresolved
The numbers are becoming too large for the financing question to be deferred. UPI processed a record 23.66 billion transactions worth ₹29.88 lakh crore in July 2026. Volumes were about 22% higher than a year earlier and transaction value about 19% higher.
The parliamentary committee believes UPI could add another 600 million users and process between 100 billion and 150 billion transactions a month over the next five to seven years. That projection would require far larger investment in payment infrastructure and security.
UPI was subsidised to accelerate adoption. It succeeded. The policy problem has changed.
Free transactions for consumers do not make the network costless. Banks, NPCI and payment companies still have to finance the infrastructure behind every QR-code payment. The government now has to decide how much of that bill taxpayers should continue to bear and how much should shift to large commercial users.
A phased reduction in subsidies, combined eventually with MDR for selected large merchants or higher-value transactions, offers the cleaner route. Small merchants and consumers can remain protected without treating zero pricing across the entire merchant network as a permanent entitlement.
