On 27 September 2026 the Supreme Court agreed to take up a public interest litigation challenging the new Merchant Discount Rate on UPI payments. The Centre has fixed a 0.4% MDR on person-to-merchant UPI transactions above ₹2,000, effective 15 October 2026. This ends a long spell in which UPI merchant payments carried no charge at all. The petition questions the amended Section 10A of the Payment and Settlement Systems Act, 2007. For exams the item links digital payments, NPCI, banking regulation and judicial review of economic policy.
The Supreme Court on 27 September 2026 agreed to hear a public interest litigation challenging the Merchant Discount Rate now imposed on high-value UPI merchant payments. The matter was listed before a bench of Chief Justice of India Surya Kant, Justice Joymalya Bagchi and Justice V Mohana for 28 September 2026. The petitioner is Advocate Anjan Datta. The immediate trigger is the MDR framework notified in September 2026, which takes effect on 15 October 2026.
The listing took place on 27 September 2026 at the Supreme Court of India in New Delhi. The MDR framework itself applies across India wherever UPI is accepted. India is the world's largest retail real-time payments market by transaction count, so a pricing change here has global significance for digital payment design.
UPI was launched by NPCI in 2016 as an interoperable, mobile-first retail payment system built on the Immediate Payment Service rails. Merchant payments on UPI and on RuPay debit cards were subsequently made free of MDR, and that zero-charge regime ran for close to six years before the present change. Payment systems in India have been regulated by the Reserve Bank of India under the Payment and Settlement Systems Act, 2007, which supplies the statutory base for both the earlier waiver and the current levy.
India runs its retail real-time payment system as a public utility built by NPCI, while comparable systems elsewhere are largely bank-owned or private. Card networks in most markets charge merchants an interchange-plus fee, and India's earlier zero-MDR model for UPI was unusual in removing that charge entirely. The 0.4% rate now set for high-value UPI merchant payments is lower than typical credit card MDR levels, and is structured with caps and sector carve-outs that most card schemes do not use.

PYQ 2:
Consider the following statements regarding the UPI Merchant Discount Rate framework:
The Merchant Discount Rate applies to person-to-merchant transactions above ₹2,000.

PYQ 3:
Assertion (A): The new Merchant Discount Rate framework leaves the great majority of UPI merchant payments unaffected.
Reason (R): The Merchant Discount Rate is levied only on person-to-merchant transactions above ₹2,000.
A) Both A and R are true, and R is the correct explanation of A
B) Both A and R are true, but R is not the correct explanation of A
C) A is true but R is false
D) A is false but R is true
Answer: A
Explanation: The levy begins only above ₹2,000, and merchant payments up to that value form the bulk of UPI merchant volumes, so the threshold is exactly why most payments stay untouched.
Question 1 (150 words): Examine the rationale for reintroducing a Merchant Discount Rate on high-value UPI merchant payments.
The reintroduction of MDR rests on a simple proposition: a payment network that carries crores of transactions cannot run indefinitely without a revenue model. For close to six years UPI merchant payments carried no charge, and banks and payment service providers absorbed the cost of switching, settlement, fraud control and dispute resolution. The framework now sets 0.4% on person-to-merchant transactions above ₹2,000, effective 15 October 2026, while leaving smaller payments free.
The design shows careful targeting. The ₹2,000 threshold protects everyday retail payments, the ₹300 cap for payments of ₹75,000 and above prevents the levy from punishing large transactions, and the flat ₹5 rate for railways, telecom, insurance, fuel and agricultural inputs shields thin-margin essential sectors. Small merchants receiving up to ₹1 lakh a month through QR codes stay exempt.
The way forward lies in ensuring the charge is genuinely absorbed within the merchant ecosystem and not quietly transferred to customers.
Question 2 (250 words): Digital payment pricing in India sits at the meeting point of economic policy and judicial review. Discuss with reference to the Merchant Discount Rate on UPI.
India's digital payments architecture was built on a deliberate policy choice: make merchant acceptance free so that adoption spreads fast. UPI, launched by NPCI in 2016, grew on that model, and merchant payments on UPI and RuPay debit cards were exempted from MDR for close to six years. The exemption achieved scale but left the cost of running the network unpriced.
The framework notified in September 2026 changes that. A rate of 0.4% applies to person-to-merchant payments above ₹2,000 from 15 October 2026, with a ₹300 cap at ₹75,000 and above, a flat ₹5 for essential sectors, and 0.02% for securities and mutual funds. Person-to-person transfers and payments up to ₹2,000 remain free.
The petition before the Supreme Court moves the question from economics to constitutional law. It argues that the levy lacks adequate statutory safeguards, transparency and public consultation, and it questions the constitutional validity of the amended Section 10A of the Payment and Settlement Systems Act, 2007. It further alleges arbitrary discrimination between UPI and RuPay debit cards. A bench of Chief Justice of India Surya Kant, Justice Joymalya Bagchi and Justice V Mohana will consider it.
The deeper issue is institutional. Courts traditionally give the executive wide latitude in economic policy, intervening mainly where a levy lacks statutory backing or where classification is arbitrary. The balanced course is for the government to place its statutory basis and consultation record clearly on the table, so that a policy touching crores of daily transactions rests on secure legal ground rather than on administrative convenience.
