NEW DELHI: UPI processes about half the world’s real-time payments and charges the merchant nothing. A decade in, the interesting question is no longer whether the model works. It is what funds it.
In FY 2025-26 the Unified Payments Interface carried 24,161.69 crore transactions worth roughly ₹314 lakh crore, with 703 banks live on the network against 21 at launch in April 2016. This desk computes the average transaction at about ₹1,300 and daily volume at 66.2 crore. The International Monetary Fund has recognised it as the world’s largest real-time payment system by volume, at about 49 per cent of the global total.
Underneath the aggregate the network splits cleanly in two. Person-to-merchant traffic is 63 per cent of volume; person-to-person traffic is 71 per cent of value. And 86 per cent of person-to-merchant payments are below ₹500. The system that clears half the world’s instant payments is, in most of its transactions, replacing a hundred-rupee note.
One rail, two businesses. High-volume, low-value merchant payments and low-volume, high-value personal transfers cost a bank roughly the same to process and generate entirely different economics.
The transaction is free. The rail is not. Every serious question about the next decade of Indian payments follows from that sentence.
At a Glance
• FY 2025-26 volume: 24,161.69 crore transactions
• FY 2025-26 value: about ₹314 lakh crore
• Year-on-year growth: 30.0% by volume, 20.59% by value
• Average transaction (this desk’s computation): about ₹1,300
• Banks live: 703 as on March 2026
• Volume split: P2M 63%; value split: P2P 71%
• Small-ticket: 86% of P2M under ₹500; 59% of P2P under ₹500
• Share of India’s digital payments: 85% in FY 2025-26
• Live abroad in: eight jurisdictions
Note first that volume is growing faster than value — 30.0 per cent against 20.59 per cent year on year. The average ticket is falling. Each additional year of adoption brings in smaller payments, because the transactions still being made in cash are the smallest ones remaining. That is exactly what successful financial deepening looks like, and it is also what makes the unit economics harder every year: the cost of processing a payment does not fall with its size.
The two halves of the rail therefore carry opposite commercial logic. Merchant acceptance is a high-frequency, zero-fee, cost-only business for the acquiring bank and the payment service provider. Personal transfers carry the value but generate no merchant discount rate either, and no meaningful float, because settlement is instant by design. This is not a flaw in the system; it is the design. Interoperability by mandate and zero merchant discount rate on small-value transactions are precisely why the network reached 703 banks rather than fragmenting into competing closed wallets, and why it works identically for a listed retailer and a vegetable seller.
Where does the return sit, then? In three places, and each is already visible. Credit is the largest: overdraft lines and credit-card linkage on UPI turn a payment rail into a distribution channel for lending, and a merchant’s transaction history into an underwriting signal that did not exist five years ago for the informal sector. Cross-border is the second: UPI acceptance is live in eight jurisdictions, and remittance and travel flows price on entirely different economics from domestic retail. The data layer is the third and the most carefully bounded — account aggregation and consent-based financial data sharing, which convert transaction records into products the customer opts into.
For a bank or a fintech the strategic conclusion is that UPI should be modelled as customer acquisition and underwriting infrastructure rather than as a payments revenue line. For policy, the constructive step is to keep the small-merchant transaction free while allowing the credit layer above it to price properly — because the 86-per-cent-under-₹500 figure is the strongest evidence that this rail has brought the smallest traders in India into a formal transaction record. That is a public asset whose value was never going to show up in fee income, and the work of the next decade is to fund the rail from what it enables rather than from what it moves.
