Your Free UPI Tap Still Runs Through PhonePe and NPCI

UPI processed 24.51 billion payments in August, a new monthly record. The National Payments Corporation of India put the value at ₹29.82 lakh crore, just under May’s peak of ₹29.90 lakh crore.

The screen still says paid in a second. The parties that actually move that rupee, and the ones that have been eating the cost since zero MDR began in January 2020, sit one layer down: NPCI’s switch, the payer’s bank, and two private apps that still take most of the taps.

The Switch That Moves Money After You Tap

A kirana payment of ₹100 never travels from PhonePe to a shop the way a text message does. The app you open is a third-party application provider, a TPAP, sitting on a member bank that NPCI calls a payment service provider. That bank packages the debit, and NPCI’s central switch looks up the payee’s virtual payment address in its mapper, then asks the remitter bank to take the money and the beneficiary bank to put it in.

The green tick is an authorisation message coming back up that chain. The banks do not square their books in that same second. A World Bank case study of India’s fast payments describes deferred net settlement through RBI accounts, with multilateral net positions passed into the central bank’s RTGS system. You see instant. They settle later, in batches.

THE FIVE PARTIES ON A SINGLE TAP

• The payer app: PhonePe, Google Pay, Paytm or another TPAP collects the VPA, amount and UPI PIN and never holds the deposit itself.
• The payer bank: The PSP member checks the PIN, the balance and the account status, then posts the debit.
• NPCI’s switch: The mapper resolves the address and the central switch routes debit and credit messages between member banks.
• The payee bank: The beneficiary’s core system posts the credit and sends a success or fail code back through the same path.
• The payee app: The shop’s app, or a QR that points at its VPA, only displays the result once NPCI confirms the hop.

Failed payments make that split visible. When a merchant refund sits in limbo, the chase goes to the bank that posted the debit, not to the brand on the icon, because NPCI’s switch is a router, not a helpdesk. Wallet-funded merchant payments above ₹2,000 already sit outside the free bank-account path and can carry an interchange of up to 1.1%, paid in the acquirer chain, not by the person tapping Pay.

PhonePe and Google Pay Still Take Four in Five

NPCI’s August product table shows 752 banks live on UPI in August, up from 741 in July and from 21 banks when the rail went live in 2016. The front end is much narrower. NPCI’s July payer-app volume tables still give most of the country to two TPAPs.

JULY 2026 UPI PAYER-APP SHARES

PhonePe, backed by Walmart, processed 10.86 billion July payments. Google Pay processed 7.65 billion. Together they took more than three-fourths of volume and an even larger slice of value, 78.22% and 81.83%. Paytm stayed third at 1.90 billion payments. The top three apps accounted for 86.28% of volume and 88.68% of value on a month in which UPI ran 23.66 billion payments worth ₹29.88 lakh crore.

Navi’s share rose to 4% in July, 94.7 crore payments worth ₹48,318 crore, which is why the combined PhonePe and Google Pay slice has drifted under 80% after years above that line. BHIM, the app NPCI itself operates, was at 0.98% in June. The banks that actually debit and credit the accounts still do not own the screen most people tap.

A 30% Cap That Has Slipped to December

NPCI has, on paper, already banned this shape of market. In November 2020 it told TPAPs that no third-party app could process more than 30% of UPI volume, measured on a rolling three-month window, with bank-owned apps left outside the cap. An app over the line was meant to stop onboarding users. PhonePe is still 15.89 points above that line. Google Pay is 2.33 points above it.

THE 30% RULE’S MOVING DEADLINE

1. November 2020: NPCI issues the 30% TPAP volume cap, to be measured on a rolling three-month basis.
2. December 31, 2024: The then-current compliance deadline, already pushed once from the original window, arrives with PhonePe and Google Pay still far above 30%.
3. December 31, 2026: NPCI extends the timeline again, saying existing TPAPs over the cap have two more years to comply.

The December 2024 circular put the new date in one sentence: “Considering various factors, the timeline for compliance of existing TPAPs who are exceeding the volume cap, is extended by two years till December 31, 2026.” Vishwas Patel, then speaking as chairman of the Payments Council of India, welcomed the extra time and said people would choose from dozens of new UPI apps. Four months remain on that clock. July’s table still reads like 2020.

Who Pays for a Free UPI Payment?

Users do not. Small shops do not, on bank-account UPI. That has been true since January 2020, when the government set merchant discount rate at zero on UPI and RuPay debit to get QR codes onto counters. The cost did not vanish. Banking officials put the operating cost in August at ₹0.4 to ₹1 per transaction, money spent on switches, fraud controls, uptime and the fee NPCI charges members to use the rail.

Someone will have to pay the cost.

Sanjay Malhotra, Governor, Reserve Bank of India, 5 August 2026

Malhotra said that cost is being borne by banks and NPCI. The Union budget has been writing cheques as well. The incentive scheme paid ₹1,046 crore in FY2024-25, at 0.15% on person-to-merchant payments of up to ₹2,000 at small merchants, so a ₹1,000 kirana tap could send ₹1.50 back into the chain. Cumulative budgetary support under the scheme has reached ₹8,276 crore. By the end of FY2024-25, 56.86 crore QR codes had been issued to about 6.5 crore merchants, and the Payments Infrastructure Development Fund had put 5.45 crore digital touch points into tier-3 to tier-6 centres by 31 October 2025.

WHAT THE FREE RAIL ACTUALLY COSTS

• Per-transaction cost: Banking officials put UPI’s operating cost at ₹0.4 to ₹1, a bill that now sits with banks and NPCI rather than with the person who taps Pay.
• Annual incentive: The BHIM-UPI scheme disbursed ₹1,046 crore in FY2024-25, at 0.15% on small-merchant payments up to ₹2,000.
• Cumulative support: Budgetary support for the zero-fee model has totalled ₹8,276 crore, on top of what member banks spend on their own switches.
• Zero-MDR start: January 2020 removed the conventional merchant fee on UPI and RuPay debit, which is the rule Parliament has now given itself room to unwind.

Across FY2025-26, UPI handled 24,160 crore payments worth ₹314 lakh crore, 85% of India’s digital payments by volume. That scale is why the zero-fee statute is under pressure. The Taxation and Other Laws (Amendment) Bill, 2026, passed by the Lok Sabha on 6 August, amends Section 10A of the Payment and Settlement Systems Act, 2007, so the government can notify which transactions may carry a charge. Finance Minister Nirmala Sitharaman has said consumers will not be charged and that an NPCI-headed UPI and Services Steering Committee will take up MDR only after both Houses finish the bill. The live change is the enabling clause, because a later notification could move the line without another trip through Parliament.

Large Shops Are Already Counting the Fee

Draft numbers in circulation this month are not a tariff. Industry talks have put a possible levy in several bands, including 0.05% to 0.07% for merchants above about ₹1 crore to ₹1.5 crore of turnover, and 0.25% to 0.35% on payments above ₹2,000 at larger firms. Payments-industry estimates say those higher-value taps are a thin slice of volume and about two-thirds of value. Rajiv Anand, managing director of IndusInd Bank, has said eligible higher-value person-to-merchant payments could support an MDR of around 20 to 25 basis points, with P2P and low-value shop payments left out.

LocalCircles, which polled 32,000 merchants, found only 17% willing to bear a 0.3% MDR on payments above ₹2,000, and 41% against any MDR. A separate August reading from the same survey house found 53% of consumers ready to leave UPI if a charge hit their own payments. A 0.3% fee on a large bill is small on a spreadsheet and loud on a counter that runs thousands of tickets, which is why shops on thin margins will try to pass it, set a floor, or ask for cash. The refund lag already teaches a related lesson: the brand on the phone is not the party that holds the money, and a fee charged in the acquirer chain will show up as a short credit long before it shows up as a line on a customer’s screen.

Credit-card UPI already has an MDR. Wallet UPI above ₹2,000 already has interchange. The political fight is about the bank-account tap that built the QR forest, and about whether PhonePe and Google Pay, which already own the customer file, would also take a share of any new merchant fee. That is the stakeholder the volume cap was meant to shrink, and has not.

The Same Rail Now Runs in 11 Countries

NPCI International Payments Ltd, set up in April 2020, has taken the same switch abroad. UPI is live in the United Arab Emirates, France, Bhutan, Sri Lanka, Nepal, Singapore, Mauritius, Qatar, Cambodia, Greece and the Maldives, with merchant QR in nine of those markets and remittance-style links in the others. Uzbekistan signed a commercial deal in late August so Indian apps can scan UZQR; that corridor is not live yet. The export is the public rail. The apps a traveller opens in Dubai or Singapore are still, in most cases, the two that dominate at home.

Minister of State for Finance Pankaj Chaudhary told the Lok Sabha in December 2025 that the IMF’s June 2025 paper, Growing Retail Digital Payments, had already called UPI the world’s largest retail fast-payment system by volume. The 49% of global real-time payment volume figure in that reply comes from ACI Worldwide’s Prime Time for Real-Time 2024 report, not from the IMF paper itself.

ACI 2024 GLOBAL REAL-TIME VOLUME

August added another record on the domestic side, 24.51 billion payments, 3.6% above July’s 23.66 billion, with daily volume up to 791 million from 763 million. Value slipped 0.2% to ₹29.82 lakh crore and was 20% above the ₹24.85 lakh crore of August a year earlier. Volume was 24.51 billion against 19.63 billion a year earlier. The next fee decision sits with the NPCI-headed committee, on a rail whose public switch still feeds two private screens, while the 30% cap comes due in December.
