Part of UPI’s new MDR revenue will fund QR infrastructure expansion across Tier-3 to Tier-6 cities through a Small Merchant Support Fund.
NEW DELHI: India’s Unified Payments Interface will begin charging merchants a Merchant Discount Rate (MDR) on select high-value transactions from October 15, 2026, ending six years of blanket zero-fee processing since the policy took effect in January 2020. However, the reform leaves untouched the transactions that matter most to ordinary Indians: every person-to-person transfer and every merchant payment up to ₹2,000, stays completely free.
The new framework emerged from a chain of regulatory steps compressed into barely five weeks. Parliament passed the Taxation and Other Laws (Amendment) Bill, 2026 during its Monsoon Session in August, amending Section 10A of the Payment and Settlement Systems Act, 2007 to replace an absolute statutory ban on UPI fees with a flexible mechanism. The Ministry of Finance followed with a Gazette notification on September 14 preserving statutory protection for RuPay debit cards and UPI payments up to ₹2,000. A day later, the National Payments Corporation of India released the operational circular spelling out rates, caps and revenue-sharing, as finalised by its 22-member UPI & Services Steering Committee.
Why Free Stopped Being Sustainable
Zero-MDR did exactly what it was designed to do. UPI processed 241.62 billion transactions worth ₹314.23 lakh crore in FY26 alone, capturing more than 85% of India’s retail digital payment volume. Yet that scale came at a cost nobody was pricing. Industry data placed before the Parliamentary Standing Committee on Finance pegged the average operational cost of a single UPI merchant transaction at ₹1.38, translating into roughly ₹20,700 crore in projected FY27 ecosystem expenditure. Meanwhile, the government’s budgetary subsidy for low-value transactions covered barely 9.66% to 11% of that requirement across recent years, leaving a shortfall running into thousands of crores.
Consequently, banks and fintech application providers found themselves absorbing costs without recovering them. Issuing banks funded account debits and fraud checks without interchange revenue, while acquiring banks and payment aggregators bore merchant onboarding expenses with no unit economics to justify them. The Standing Committee concluded in March 2026 that annual budgetary appropriations were too volatile to support multi-year infrastructure planning and technical decline rates during peak hours reportedly worsened as a result.
The Arithmetic Behind the ₹2,000 Line
The threshold was not arbitrary. Transactions up to ₹2,000 account for 95% to 96% of all merchant payment volume, yet payments above that mark just 4% to 5% of volume generate approximately 65% of total merchant transaction value. By drawing the line precisely there, regulators shielded nearly every kirana store, tea stall and street vendor sale while still capturing the commercial value that flows through larger-ticket purchases.
Above ₹2,000, standard merchant payments now attract a 0.40% MDR, capped at ₹300 for tickets of ₹75,000 and beyond. Utilities, telecom, insurance, fuel, railways and government services get a flat ₹5 charge regardless of transaction size, while capital market transactions face a concessional 0.02%, also capped at ₹300. Small merchants receiving under ₹1,00,000 monthly remain fully exempt. Notably, the revenue itself follows a defined waterfall: 5% funds a Small Merchant Support Fund for QR deployment in Tier-3 to Tier-6 towns, while the remaining pool splits into a 0.28% issuer interchange, a 0.12% acquirer margin and a further 0.8% share of that margin routed to app providers such as PhonePe, Google Pay and Paytm.
Winners, Absorbers and a Live Debate
Organised retailers and e-commerce platforms will absorb most of the new cost, a business processing ₹10 crore monthly in high-ticket UPI payments faces roughly ₹40,000 in additional charges, according to industry calculations. Banks and fintechs, conversely, stand to gain: Jefferies estimates the reform generates ₹5,000 crore to ₹10,000 crore annually for the industry, while Bernstein projects that figure could reach ₹22,000 crore by FY28, though these remain analyst projections rather than confirmed outcomes. Consumers, meanwhile, are explicitly barred from bearing any pass-through cost, with surcharging declared illegal under the new rules.
Not everyone is convinced the transition is risk-free. A LocalCircles survey of 20,000 respondents found 12% might cut UPI usage if merchants attempted to pass on charges, feeding concerns among inclusion advocates that friction could nudge some transactions back toward cash. Proponents counter that a 0.40% capped fee remains far cheaper than the 1.5% to 2.5% charged on credit cards, positioning UPI as still the most economical acceptance option available to Indian businesses.
What to Watch After October 15
Regulators will be tracking several signals closely. One is transaction splitting, whether merchants fragment bills into sub-₹2,000 tickets to dodge fees, visible in any unusual clustering around the ₹1,800 to ₹1,999 band. Another is surcharging compliance, monitored through grievance volumes filed with the RBI Ombudsman. A third concerns whether banks actually reinvest MDR revenue into infrastructure, reflected in whether technical decline rates improve and whether the Small Merchant Support Fund reaches rural QR deployment at the pace promised.
For now, the reform marks a deliberate bet: that a payments network processing over ₹300 lakh crore annually needs a durable funding model rather than fragile annual subsidies and that calibrated pricing on India’s highest-value transactions can fund the security and capacity upgrades its next phase of growth will demand.
