UPI, MDR and Who Pays for Digital Payments: A CDS/OTA Economy Explainer

By Aditya Tiwari · 8 Aug 2026 · 9 min read

On 8 August 2026, the Ministry of Finance stated categorically that UPI users will face no transaction charges, that all person-to-person transfers remain free, and that any future Merchant Discount Rate (MDR) would apply only to a limited set of merchant transactions above a threshold, at a nominal rate far lower than card MDR. The amendment to the Payment and Settlement Systems Act is described as an enabling provision for UPI's long-term sustainability. For a CDS/OTA aspirant this is a compact economy topic that teaches something most candidates never think about: who actually pays for a "free" payment.

The news in one frame

The essentials:

No charges for users — consumers making payments face no transaction charge.
P2P stays free — all person-to-person transactions remain free of charge.
Nominal MDR for merchants, if introduced — only on a limited set of merchant transactions above a certain threshold, at a rate far lower than debit or credit card MDR.
The vast majority of transactions remain free for merchants too.
The legal step: an amendment to the Payment and Settlement Systems (PSS) Act as an enabling provision — for financial inclusion, UPI's long-term sustainability, technological advancement and resilience against emerging risks.

What MDR actually is

Start with the definition, because the whole debate turns on it:

MDR — Merchant Discount Rate — is the fee a merchant pays to its bank for accepting a digital payment, expressed as a percentage of the transaction. The customer never pays MDR.
It is split three ways: the interchange fee to the issuing bank (the customer's bank), a fee to the acquiring bank (the merchant's bank), and a network/switch fee to the payment network.
Card MDR in India has historically run in the range of 1-2% for credit cards, with debit-card MDR capped lower.
Zero-MDR on UPI and RuPay debit cards was mandated from January 2020 to accelerate adoption. It worked spectacularly on volumes — but it also meant the system's running costs had no revenue stream attached to them.

The economics — the point worth teaching

This is the analytical section, and where marks lie:

A payment that is free to both sides is not costless. Somebody pays for servers, bandwidth, fraud monitoring, customer support, settlement systems and cyber-security — and for the engineering to keep the system up during festival-day traffic peaks.
With zero MDR, that cost falls on banks and payment service providers, partly offset by government incentive schemes. Critics argue this leaves the ecosystem dependent on subsidy and under-invested in fraud prevention and resilience — precisely the "emerging risks" the ministry's statement names.
The counter-argument for keeping it free is equally strong: zero MDR is what made UPI universal. A small shopkeeper who must pay 1% on every sale has an obvious incentive to prefer cash — and once merchants push back to cash, the entire digital-inclusion gain unwinds.
The stated resolution is a middle path: keep it free for consumers and for the small merchant, and levy a nominal charge only on larger merchant transactions above a threshold — those best able to absorb it. Whether the threshold is set high enough to protect small traders is the question a thoughtful candidate would ask.

This economy material is exactly what the CDS/OTA notes on the economy build.

The institutional and legal frame

The bodies and laws the exam matches:

NPCI — National Payments Corporation of India, set up in 2008 as a not-for-profit company under Section 8 of the Companies Act, promoted by the RBI and the Indian Banks' Association. It is the umbrella organisation for retail payments.
NPCI's products: UPI, RuPay (card network), IMPS (instant transfer), AePS (Aadhaar-enabled, biometric), NACH (bulk mandates), NETC/FASTag (tolling), BHIM (app), and UPI Lite for small offline payments.
PSS Act — Payment and Settlement Systems Act, 2007 — the statute under which the RBI authorises and regulates payment systems in India. The amendment referred to here operates within that framework.
RBI is the regulator; the Board for Regulation and Supervision of Payment and Settlement Systems (BPSS) oversees the area.
International reach: UPI has been linked with several countries — including Singapore's PayNow, and acceptance arrangements in Nepal, UAE, France, Sri Lanka, Mauritius, Bhutan and others — through NIPL, NPCI International Payments Ltd.
Related architecture: JAM trinity (Jan Dhan, Aadhaar, Mobile) enabling DBT; ONDC for open commerce; and the wider idea of Digital Public Infrastructure, of which UPI is India's best-known export.

These themes recur in the CDS/OTA daily current affairs.

The revision hook: MDR = Merchant Discount Rate, paid by the MERCHANT (never the consumer), split between issuing bank (interchange), acquiring bank and network; zero-MDR on UPI and RuPay debit from January 2020; the 8 Aug 2026 clarification — no consumer charges, P2P free, any MDR only on limited merchant transactions above a threshold at nominal rates, vast majority free; amendment to the Payment and Settlement Systems Act 2007 as an enabling provision; NPCI founded 2008, a not-for-profit Section 8 company promoted by RBI and IBA, runs UPI, RuPay, IMPS, AePS, NACH, NETC/FASTag, BHIM, UPI Lite; RBI is the regulator; NIPL takes UPI abroad — Singapore PayNow, Nepal, UAE, France and others; UPI is the flagship of India's Digital Public Infrastructure.

The wider significance

Round out with what UPI actually changed:

Interoperability was the design masterstroke: any app can pay any account at any bank. Contrast this with closed wallet systems, where money inside one company's app could not reach another's.
Cost per transaction near zero made micro-payments viable — a ten-rupee payment is worth making digitally, which is not true where a fixed fee applies.
The QR code did the last mile: a street vendor needs no card machine, no rental and no electricity — just a printed code.
Data trail with inclusion: a transaction history is a credit history, which is how digital lending to small merchants became possible at all.
The risk side, honestly stated: rising cyber fraud and social-engineering scams, concentration risk in a few large apps, and the outage question — when a system carries this much of a country's payments, resilience is a public interest, not a private one.

Why it matters

For the essay/interview and bigger picture:

Inclusion: UPI put the same payment rails under a corporate treasury and a vegetable seller — a genuinely rare piece of egalitarian infrastructure.
Formalisation: digital records pull transactions into the formal economy, widening the tax base without new taxes.
Sustainability: infrastructure that is free forever must still be paid for by someone — and deciding who, fairly, is what this announcement is about.

Exam relevance in one paragraph

For CDS/OTA GK, retain: on 8 August 2026 the Finance Ministry clarified that UPI consumers will face no transaction charges, that all person-to-person transactions remain free, and that any Merchant Discount Rate, if introduced, would apply only to a limited set of merchant transactions above a threshold at a nominal rate far below debit or credit card MDR, with the vast majority of transactions remaining free, the amendment to the Payment and Settlement Systems Act, 2007 being an enabling provision for financial inclusion, UPI's long-term sustainability and resilience against emerging risks; MDR is the fee paid by the merchant, never the consumer, and is split between the issuing bank as interchange, the acquiring bank and the network, with zero MDR having been mandated on UPI and RuPay debit cards from January 2020; UPI is operated by the National Payments Corporation of India, established in 2008 as a not-for-profit Section 8 company promoted by the Reserve Bank and the Indian Banks' Association, which also runs RuPay, IMPS, AePS, NACH, NETC/FASTag, BHIM and UPI Lite, all regulated by the RBI, while NPCI International Payments Ltd has taken UPI to partners including Singapore's PayNow, Nepal, the UAE and France; UPI's design advantages are interoperability, near-zero cost per transaction, QR-based acceptance and the credit history a transaction trail creates, while its risks are cyber fraud, concentration in a few apps and system resilience. For the essay, frame it as free to use, but never free to run.

📋 How this gets asked (PYQ pattern)

Digital payments are a reliable CDS/OTA economy set. The reliable framings are who pays MDR (the merchant), NPCI's year, status and product list, the PSS Act as the governing law, and the JAM trinity. A common trap states that MDR is charged to the consumer, or calls NPCI a government department (it is a not-for-profit company). The fresh 2026 hook is the no-charges clarification and the PSS Act amendment — ideal for "who pays / which body / which Act" items. We reference the pattern, not any exact past question.
