The Story
UPI processed 24.51 billion transactions in August, a monthly record, according to National Payments Corporation of India data released on Tuesday. Volume rose 22 per cent from a year earlier and 3.6 per cent from July's 23.66 billion.
Transaction value came to ₹29.82 lakh crore, up 20 per cent year on year but slightly below July's ₹29.88 lakh crore. The system handled about 791 million transactions a day in August against 763 million in July, while average daily value edged down from ₹96,383 crore to ₹96,205 crore.
That arithmetic leaves an average transaction of roughly ₹1,217 in August, down from about ₹1,263 in July. Around 850 million more payments, each of them smaller.
IMPS recorded 360 million transactions worth ₹7.04 lakh crore, an 18 per cent rise in value year on year, averaging 11.61 million transactions and ₹22,701 crore a day.
The decade-scale figures remain extraordinary. Annual volume has gone from 2 crore transactions in FY2016-17 to more than 24,162 crore in FY2025-26, close to a 12,000-fold increase, while annual value rose from ₹0.07 lakh crore to about ₹314 lakh crore. The network counted 741 live banks as of July. UPI merchant payments now work in around ten overseas markets including Singapore, the UAE, France, Sri Lanka, Nepal and Qatar, and NPCI International recently added a tie-up with Uzbekistan's HUMO network.
Concentration has not shifted. PhonePe and Google Pay together handled about 80 per cent of UPI volume and 83 per cent of value in July, across an ecosystem of 47 third-party apps.
Why It Matters
A falling ticket size is not a weakness in the rail. It is the clearest evidence that UPI is doing what it was built to do, pushing further into the small everyday payments that used to be cash. Nobody should read ₹1,217 as a warning about adoption.
It is a problem for the economics, though, because of where the money sits.
Transactions above ₹2,000 accounted for roughly 4 per cent of person-to-merchant UPI volume in FY26, and about two-thirds of the value moving through the system. That narrow band is precisely what the industry's revenue proposal targets. The Taxation and Other Laws (Amendment) Bill, 2026 opens the way to a merchant discount rate on large-merchant UPI and RuPay debit payments above a turnover threshold, with consumers paying nothing and all person-to-person transfers staying free. The bill still needs Rajya Sabha passage and presidential assent.
So the fix rides on the top 4 per cent of transactions while the growth arrives from the bottom. Jefferies estimates an MDR of 15 to 30 basis points on payments above ₹2,000 could generate ₹5,000 to ₹10,000 crore by FY28. Running the ecosystem is estimated to cost around ₹20,000 crore a year. Even the favourable case covers half of it, and it covers that half by taxing the one segment that is growing slowest.
The Finance Ministry, on any future merchant discount rate: it would apply only above a threshold, on a limited set of merchant transactions, and at a rate "far lower" than debit or credit card MDRs.
The Strategic Read
Ten years in, India has built the most widely used real-time payment system in the world and still has not settled who pays for it.
The zero-MDR regime followed the Nilekani committee's 2019 recommendation that merchant fees be scrapped for consumers and small merchants, with the government subsidising instead. As adoption policy that worked spectacularly. As financing it has worked less well. The Centre paid ₹8,730 crore in UPI incentives between FY22 and FY25, which the Standing Committee on Finance assessed as covering about 11 per cent of the payment industry's costs. The other 89 per cent has been carried by banks and payment service providers, funded largely by capital raised on the expectation that monetisation would arrive later.
For anyone building on this rail, that is the thing worth internalising. UPI is genuinely free public infrastructure for consumers and genuinely expensive private infrastructure for the companies running it. Lending, wealth and commerce businesses built on UPI distribution are subsidising their own acquisition channel and calling it a moat. That subsidy may narrow.
The second unresolved question carries a date. NPCI's 30 per cent market-share cap, first proposed in 2020 and deferred repeatedly, currently falls due in December. PhonePe and Google Pay hold about 80 per cent of volume between them. Enforcing it means moving roughly half of India's payment traffic onto different apps within months. Deferring again concedes the cap is unenforceable. There is no third option, and the deadline is four months away.
The two questions also pull against each other. Business Standard reports that under an MDR regime, apps holding both merchant and consumer bases would take the larger share of the pool while payer-side apps get less. That favours PhonePe, Google Pay and Paytm. A monetisation model that entrenches the incumbents makes a concentration cap harder to impose, not easier. NPCI will have to decide which of the two problems it minds more.
