Fintech Weekly Deep Dive — UPI’s Free Ride Ends | Week of August 17–23, 2026

Executive Summary

India is about to end the most ambitious free-payment experiment in financial history. On August 10, Parliament passed the Taxation and Other Laws (Amendment) Bill, 2026, amending Section 10A of the Payment and Settlement Systems Act, 2007. The amendment removes the statutory bar on charging fees for digital payments and empowers the UPI Steering Committee to implement a targeted Merchant Discount Rate (MDR) framework.

This is not a sudden policy reversal. It is the logical endpoint of six years of an unsustainable fiscal model: the government pays ₹2,000 crore in annual subsidies to cover roughly 11% of the ₹20,000 crore it actually costs banks, NPCI, and payment service providers to run UPI. The gap has been widening as volumes scale — July 2026 alone saw 23.66 billion transactions worth ₹29.9 lakh crore.

The government has repeatedly clarified that consumers will not pay. P2P transfers remain free. Small merchants — the kirana stores, street vendors, and local service providers who form the backbone of UPI adoption — remain free. What changes is that large merchants — the Amazons, Swiggys, Dream11s, and Zeptos — may soon bear a nominal fee of 25–30 basis points, a fraction of the 1.8–2% they already pay on credit cards. The question is no longer whether UPI MDR will return, but how the rules are written — and that is where the consumer battle will be fought.

The Story in Depth

Context: Six Years of “Free” That Were Never Free

UPI launched on April 11, 2016 as a pilot with 21 banks. By 2020, the government had made a strategic decision: waive the 30-basis-point MDR that had existed since inception, and subsidise the gap through budgetary allocations. The rationale was unassailable — India had 200 million UPI users in 2020, and the zero-fee model was the fastest way to onboard the next 300 million.

It worked. UPI now has over 55 crore active users, 703 ecosystem entities, and processes 86% of all non-cash digital transactions in India. Annual digital transactions reached 28,174 crore in FY2025-26. The system is live in 11 countries, with more in the pipeline. By any metric, this is the most successful retail payment system ever built.

But scale created a cost monster. Every UPI transaction triggers authorisation, settlement, reconciliation, fraud screening, and dispute handling — round-the-clock operations across 703 entities. Economist Ajit Ranade estimates the annual cost of running UPI at ₹20,000 crore. The Parliamentary Standing Committee on Finance, chaired by Bhartruhari Mahtab, corroborated this in its March 2026 report, finding that the government’s incentive scheme covers “merely 11% of the industry’s actual costs and 14% of potential MDR collections, creating a structural funding gap.”

The subsidy trajectory tells the story of strain: ₹1,389 crore in FY2021-22, rising to ₹2,210 crore in FY2022-23, peaking at ₹3,631 crore in FY2023-24, then dropping to ₹2,196 crore in FY2025-26 (revised estimate), with ₹2,000 crore budgeted for FY2026-27. The industry, led by the Payments Council of India, has consistently argued it needs ₹10,000–15,000 crore annually.

What Happened This Week

The legislative dam broke on August 10 when Parliament passed the Taxation and Other Laws (Amendment) Bill, 2026. The specific amendment to Section 10A of the PSS Act is narrow but powerful: it removes the blanket statutory prohibition on charging fees for digital payments, and delegates authority to the UPI Steering Committee to design a targeted MDR framework.

What followed was a week of intense framing battles:

August 9 — Government clarification. The Finance Ministry issued an official statement confirming UPI will remain free for consumers and P2P transfers. Any MDR would apply only to selected merchant transactions above a monetary threshold, at a nominal rate. ¹

August 20 — Former RBI ED backs MDR. G. Padmanabhan, former executive director of the RBI, publicly welcomed the move, stating it is “unlikely to impact UPI volumes” and that “payment systems require continuous investments and therefore, there has to be a payment.” ²

August 21 — Forbes India deep dive on small vs. large merchant impact. A detailed analysis highlighted the structural asymmetry: large retailers like Big Bazaar or D-Mart can absorb a 0.3% fee without breaking a sweat — they already pay 2% on credit cards. But a small merchant operating on 5–8% margins could find even 0.3% meaningful if they do high-volume, low-margin business. ³

August 21 — CARD91 calls for merchant intelligence. Payment infrastructure provider CARD91 argued that any selective MDR framework requires reliable merchant classification — you cannot apply a tiered model if you cannot accurately distinguish a kirana from a startup from a multinational. ⁴

August 21 — Business Standard reports debit card rule as potential template. The debit card MDR framework — which caps charges and prevents pass-through to consumers — is being studied as a template for UPI safeguards. ⁵

August 22 — Vajiram editorial argues for keeping UPI free. An editorial analysis argued that the government should fund UPI through the savings it creates — reduced cash handling costs, better tax compliance, lower leakages — rather than recovering costs through MDR. ⁶

August 22 — Moneycontrol op-ed calls for calibrated monetisation. A Moneycontrol opinion piece argued that UPI “has won on scale, now it must win on economics,” advocating for a tiered model with continued subsidies for smaller players. ⁷

August 23 — Outlook Business reports potential 2-week timeline. Government may notify which digital payment channels attract MDR within the next two weeks, with merchant payments of ₹2,000 and above being the likely threshold. ⁸

Why It Matters

This is the most consequential policy shift in Indian digital payments since zero-MDR was introduced in 2020.

The legislative change is permanent. Unlike the subsidy model, which required annual budgetary approval and was subject to fiscal pressures, an MDR framework embedded in the PSS Act creates a structural revenue mechanism. Once implemented, it will not be easily reversed.

The consumer protection architecture is the critical variable. The government has committed to three safeguards: (1) P2P transfers permanently free, (2) small merchant transactions free, and (3) large merchants cannot pass the cost to consumers. The third safeguard is the hardest to enforce — history shows that merchants find creative ways to embed payment costs into pricing, from “convenience fees” on delivery apps to minimum order values that effectively penalise digital payment users.

The competitive dynamics are also significant. UPI processes 23.66 billion transactions a month, but 80%+ of that volume flows through just two apps — PhonePe (Walmart-backed) and Google Pay (Alphabet-backed). NPCI’s 30% market cap rule has been repeatedly deferred, now to December 2026. An MDR framework could reshape these competitive dynamics: if revenue from large-merchant MDR is distributed through NPCI’s existing framework, it could provide smaller TPAPs (Third-Party Application Providers) with the financial oxygen to compete.

Expert Views

G. Padmanabhan, former RBI Executive Director: “I don’t think [MDR] will impact [UPI] volumes. Payment systems require continuous investments and therefore, there has to be a payment.” ²

Vishwas Patel, Chairman, Payments Council of India: “With zero MDR for UPI and the government allocating a mere ₹2,000 crore for processing 30 crore transactions every day for free, it will choke the entire ecosystem for funds for scaling and growth. We were expecting government incentives to be above ₹10,000 crore.” ⁷

Abhay Johorey, MD, Protiviti India: Large retailers and e-commerce companies are “likely to be better placed to absorb a modest MDR,” but small merchants with thinner margins face a disproportionate impact. ³

Ajit Ranade, Economist: The cost of running UPI “can be charged to the RBI as it would be barely 7 percent of the huge dividend it pays annually to the Union government.” ³

Vajiram editorial analysis: “UPI should remain free at the point of use. If digitalisation saves money for the government and banks, those savings should help finance UPI rather than recovering costs through MDR from merchants and consumers.” ⁶

Moneycontrol editorial: “The stage for UPI monetisation is set. What matters now is getting the economics right.” ⁷

Consumer Impact

For the vast majority of consumers, nothing changes. P2P transfers — sending money to family, splitting bills, paying rent — remain permanently free. Small merchant payments at your local kirana, chai stall, or neighbourhood salon remain free. The government has been explicit on this.

The indirect consumer impact is more nuanced. If large merchants face MDR on UPI, some will attempt to pass costs downstream. Food delivery apps already charge platform fees and “convenience fees” — adding a payment processing surcharge is technically possible unless the regulations explicitly prohibit it. The debit card MDR framework, which the government is reportedly using as a template, includes pass-through prohibitions. But enforcement is the question.

There is also a behavioural risk. India’s cash-to-digital transition was driven partly by the zero-cost proposition. A Vajiram editorial analysis warns that “even a 0.3% charge could significantly affect merchants operating on thin margins” and could lead some to discourage digital payments or revert to cash, particularly in price-sensitive rural markets where UPI’s next growth wave is expected to come from. ⁶

The positive consumer impact is often overlooked: a sustainably funded UPI is a secure UPI. The ₹20,000 crore annual cost includes cybersecurity infrastructure, fraud detection systems, and technology upgrades. Underfunding these systems is not cost savings — it is deferred risk. The RBI’s discussion paper on digital payment fraud, the Supreme Court’s order on mule accounts, and the rise of AI-powered fraud all point to a system under increasing threat. MDR revenue, if properly allocated, could fund the next generation of security infrastructure.

Looking Ahead

Next 2–4 weeks: Watch for the formal notification from the UPI Steering Committee defining merchant classification thresholds, applicable MDR rates, and revenue distribution methodology. Outlook Business reports this could come within two weeks. ⁸

Key design questions to watch:

• How is “large merchant” defined? By annual turnover, daily transaction volume, or transaction value? The PCI proposed ₹40 lakh in annual turnover; the government may choose a different metric.
• What is the threshold per transaction? Reports suggest ₹2,000 as a floor, but the final number matters enormously for how many transactions are captured.
• How is MDR revenue distributed between issuing banks, acquiring banks, NPCI, and payment aggregators? An opaque formula could reinforce the PhonePe-Google Pay duopoly rather than democratising the ecosystem.
• Are pass-through prohibitions enforceable? The debit card template is a start, but India’s enforcement track record on merchant pricing is mixed.

September 2026: NPCI’s 30% market cap rule is currently deferred to December 2026. If MDR revenue flows disproportionately to the largest TPAPs, the market concentration problem worsens. The MDR design and market cap enforcement are two sides of the same coin.

Longer term: If UPI MDR succeeds as a revenue model, it could unlock a genuine economic moat for India’s digital payments infrastructure — funding international expansion, rural penetration, and next-generation features (programmable payments, account abstraction, cross-border interoperability) without perpetual fiscal dependence.

The risk is implementation. Get the thresholds wrong, and small merchants get squeezed. Get the revenue distribution wrong, and the duopoly calcifies. Get the pass-through rules wrong, and consumers end up paying despite government promises. This is a policy tightrope, and India is walking it with the world watching.
