UPI at 10 Years: India’s Digital Payments Revolution Now Faces the Challenge of Sustainability, Competition and Global Expansion:

Recent Developments:

• During FY2025–26, UPI processed 24,161.69 crore transactions worth approximately ₹314 lakh crore, with 703 banks live on the platform by March 2026.
• UPI accounted for about 85% of India’s digital-payment volume in FY2025–26, while its share of global real-time payment volume was estimated at 49% in 2025.
• The March 2026 monthly record reached 2,264 crore transactions worth ₹29.53 lakh crore, demonstrating the extraordinary scale of India’s retail digital-payment infrastructure.
• In August 2026, amendments to the Payments and Settlement Systems Act, 2007 created a legal pathway for a possible reintroduction of Merchant Discount Rate (MDR) on selected digital-payment transactions, although the detailed fee structure has not been finalised.
• The government has clarified that person-to-person UPI payments will remain free, while any future MDR is expected to focus on a limited category of merchant transactions rather than ordinary consumers and small merchants.

Evolution and Institutional Architecture of UPI:

Background and Genesis:

• Before UPI, India relied on multiple payment systems such as NEFT, RTGS and IMPS, creating a need for a more interoperable and user-friendly retail-payment architecture.
• The RBI’s 2012 Vision Document for Payment Systems highlighted the low penetration of non-cash payments in India and identified the need for greater electronic-payment adoption.
• NPCI, established as the umbrella organisation for retail payment systems, developed UPI to provide a common interoperable interface connecting multiple bank accounts, payment applications and merchants.
• The UPI pilot began with 21 member banks on 11 April 2016, while UPI-enabled applications became increasingly available from August 2016.

How UPI Works:

• UPI enables users to link multiple bank accounts to a single application and initiate instant payments through a common interface.
• Its architecture involves users, merchants, UPI applications, remitter banks, beneficiary banks and Payment Service Providers (PSPs).
• UPI supports Person-to-Person (P2P) and Person-to-Merchant (P2M) transactions through interoperable bank accounts.
• Payments can be initiated through Virtual Payment Addresses (VPAs), QR codes, mobile applications and intent-based payments, reducing dependence on physical cash and card infrastructure.
• Two-factor authentication and the use of virtual payment identifiers improve security by reducing the need to disclose sensitive bank-account information during ordinary transactions.

Factors Behind UPI’s Rapid Expansion:

Interoperability and Low Transaction Friction:

• UPI allows customers to use a single interface across participating banks and payment applications, thereby reducing fragmentation in the digital-payment ecosystem.
• QR-code payments, instant settlement and mobile-based authentication made digital payments accessible even for small-value everyday transactions.
• The model substantially reduced the dependence on Point-of-Sale terminals, cash handling and physical banking infrastructure.

Zero-MDR Policy:

• Merchant Discount Rate (MDR) is a fee associated with processing digital payments and is generally distributed among participants in the payment ecosystem.
• Since January 2020, MDR was made zero for RuPay Debit Card and BHIM-UPI transactions through amendments involving Section 10A of the Payments and Settlement Systems Act, 2007 and Section 269SU of the Income-tax Act, 1961.
• The zero-MDR framework lowered the cost of accepting digital payments and encouraged merchants, particularly small businesses, to adopt UPI.

Government Incentive Support:

• The Union Cabinet approved a ₹1,500 crore incentive scheme for FY2024–25 to promote low-value BHIM-UPI P2M transactions among small merchants.
• Under the scheme, transactions up to ₹2,000 involving small merchants remained subject to zero MDR while qualifying transactions received an incentive of 0.15% of transaction value.
• The incentive is paid to the acquiring bank and subsequently shared among relevant ecosystem participants, including issuer banks, PSP banks and TPAPs.
• The policy has therefore treated UPI as a form of Digital Public Infrastructure (DPI) whose adoption can generate wider economic and social benefits beyond direct transaction revenue.

COVID-19 and Digital Adoption:

• The COVID-19 pandemic accelerated digital-payment adoption because consumers and merchants increasingly preferred contactless and cash-light transactions.
• The pandemic therefore reinforced an already expanding UPI ecosystem and increased the frequency of small-value digital payments.

UPI and Financial Inclusion:

Democratization of Digital Payments:

• UPI has enabled street vendors, small retailers, transport operators and informal businesses to accept digital payments using low-cost QR codes rather than expensive card-payment infrastructure.
• Its high frequency of small-value transactions demonstrates its integration into everyday consumption and retail commerce.
• According to official FY2025–26 data, 86% of P2M transactions were below ₹500, highlighting the dominance of micro-payments in UPI usage.

Rural and Semi-Urban Expansion:

• Future domestic growth is expected to increasingly depend on Tier-3 to Tier-6 cities, rural areas and underserved populations.
• UPI 123PAY extends digital payments to feature-phone users, while UPI Lite and UPI LiteX address low-value and offline-payment requirements.
• Such innovations can reduce the digital divide by lowering dependence on smartphones, continuous internet connectivity and conventional banking infrastructure.

The MDR Debate and Sustainability Challenge:

Why the Zero-MDR Model Is Under Pressure:

• UPI’s enormous transaction volume generates substantial costs related to technology infrastructure, cybersecurity, banking systems, compliance and transaction processing.
• Zero MDR removes a conventional revenue stream from the payment ecosystem even though payment providers continue to incur operating and infrastructure costs.
• Government incentives partially compensate ecosystem participants, but questions remain regarding whether public subsidies alone can sustainably finance a rapidly expanding payment infrastructure.

Case for Reintroducing MDR:

• Industry stakeholders argue that the initial zero-MDR model was useful for rapid adoption, but the mature ecosystem now requires a more sustainable revenue model.
• A selective MDR could be imposed on high-value merchant transactions while keeping ordinary P2P payments and small-merchant transactions free.
• One proposal discussed in the current policy debate involves MDR of around 0.3–0.5% on transactions above ₹2,000 for eligible large merchants, although no final fee structure has been established.
• High-value transactions can provide a potential revenue base because they account for a much larger share of transaction value than their share in transaction volume.

Arguments Against MDR:

• Reintroducing MDR could increase operating costs for merchants and potentially lead to higher consumer prices if merchants pass the cost on to customers.
• Additional charges could discourage digital-payment adoption among price-sensitive consumers and small businesses.
• The policy could weaken one of UPI’s principal advantages, namely simple and low-cost digital transactions.
• Any poorly designed MDR could therefore undermine the very network effects that made UPI successful.

A Balanced Approach:

• A sustainable model should distinguish between P2P transactions, small-value P2M transactions and high-value merchant transactions rather than imposing a uniform charge.
• Small merchants and low-value transactions should continue to receive protection because they have the greatest significance for financial inclusion and cash-to-digital transition.
• Any MDR framework should be transparent, capped, proportionate and competition-sensitive, with adequate safeguards against cost pass-through to consumers.

Market Concentration and Competition:

Dominance of Major Third-Party Apps:

• The UPI ecosystem has experienced strong concentration among major Third-Party Application Providers (TPAPs), particularly PhonePe and Google Pay.
• Such concentration creates concerns regarding market power, systemic dependence and competitive neutrality within a payment infrastructure that has become critical to the economy.
• The concentration problem is particularly important because UPI itself is interoperable, but user behaviour can remain concentrated around a small number of dominant applications.

30% Market-Share Cap:

• NPCI introduced a 30% market-share ceiling for individual TPAPs to prevent excessive concentration in the UPI application ecosystem.
• Implementation of the cap has been repeatedly deferred because immediate enforcement could disrupt consumers and merchants dependent on dominant applications.
• The current extension runs until December 2026, making competition and market concentration an important regulatory issue for the next phase of UPI development.

Banks and FinTechs:

• Traditional banks face intense competition from FinTech companies and TPAPs in the customer-facing payments layer.
• Banks continue to provide the underlying accounts and regulated payment infrastructure, while large technology platforms have developed strong consumer interfaces, merchant networks and transaction ecosystems.
• This creates a policy challenge involving the appropriate balance between innovation, competition, consumer choice and regulatory oversight.

Internationalisation of UPI:

UPI as India’s Digital Public Infrastructure:

• UPI has increasingly become an instrument of India’s Digital Public Infrastructure diplomacy, with other countries adopting or linking their payment systems with Indian infrastructure.
• Internationalisation can reduce dependence on expensive and slower traditional cross-border retail-payment mechanisms while strengthening India’s technological and financial influence.

Cross-Border Payment Linkages:

• India has developed UPI-based payment linkages with several countries, including Singapore, Nepal, Bhutan, Mauritius, Sri Lanka, the UAE and France, while international acceptance continues to expand.
• In June 2026, NPCI International Payments Limited (NIPL) and Cambodia’s ACLEDA Bank launched the first phase of UPI acceptance through Cambodia’s KHQR system, enabling Indian travellers to make QR payments at more than 4.5 million Cambodian merchants.
• India and Nepal also operationalised a direct linkage between UPI and Nepal’s National Payments Interface (NPI) for instant P2P cross-border remittances in June 2026.
• The UPI-PayNow linkage with Singapore demonstrates how interoperable payment systems can facilitate faster and more efficient cross-border retail remittances.

UPI One World:

• UPI One World enables eligible foreign visitors to make UPI payments in India without requiring an Indian mobile number or domestic bank account.
• The service can be used across a large network of Indian QR codes and supports applications such as merchant payments, travel bookings, hotels, restaurants and transportation.
• In 2026, NPCI extended the service to international delegates from more than 40 countries, strengthening UPI’s role as a globally exportable payment technology.

Emerging Challenges:

Cybersecurity and Operational Resilience:

• The enormous scale of UPI makes cybersecurity, fraud prevention, data protection and operational resilience critical components of financial stability.
• A major disruption to UPI could affect millions of individuals and businesses because the platform has become deeply embedded in everyday economic activity.
• NPCI has continued issuing operational and security-related circulars, including measures concerning safeguarding user information and system controls.

Digital Divide:

• Smartphone ownership, internet access, digital literacy and language barriers can still restrict UPI adoption among some sections of the population.
• Feature-phone payments, offline functionality and assisted digital-payment models can help address these barriers.

Consumer Protection:

• Rising digital-payment adoption increases the importance of fraud reporting, grievance redressal, transaction reversals and customer awareness.
• UPI’s in-app grievance mechanisms and regulatory oversight need to evolve alongside the increasing sophistication of digital fraud.

Financial Sustainability:

• The central policy challenge is to ensure that the payment ecosystem remains financially viable without transforming UPI into a costly platform for ordinary users.
• A sustainable ecosystem should distribute costs fairly among merchants, payment providers, banks, technology platforms and the government, according to the benefits received by each participant.

Significance for the Indian Economy:

• UPI reduces transaction costs, facilitates formalisation and expands access to digital financial services.
• Digital payment records can improve the ability of financial institutions to assess the economic activity and creditworthiness of small businesses.
• UPI supports the broader Jan Dhan–Aadhaar–Mobile (JAM) ecosystem by strengthening the digital layer through which financial services can reach citizens.
• Its interoperability promotes competition among payment applications, even though concentration among major TPAPs remains a concern.
• UPI strengthens India’s position in Digital Public Infrastructure, alongside platforms such as Aadhaar and DigiLocker.
• International deployment of UPI can strengthen India’s fintech diplomacy, remittance infrastructure and technological influence.

Way Forward:

Sustainable and Inclusive Pricing:

• India should adopt a targeted MDR framework that protects P2P transactions, small merchants and low-value payments while allowing reasonable charges on selected high-value merchant transactions.
• Any MDR should remain transparent, capped and proportionate to transaction value and merchant capacity.

Strengthening Competition:

• The implementation of the 30% TPAP market-share ceiling should be calibrated to prevent market disruption while promoting a more diversified ecosystem.
• Greater participation by banks, domestic FinTechs and smaller TPAPs can reduce concentration risks.

Improving Rural Access:

• Expansion of UPI 123PAY, UPI Lite, UPI LiteX and offline payment capabilities should continue to reduce digital exclusion.
• Regional-language interfaces and stronger digital-literacy programmes can further expand adoption.

Enhancing Cybersecurity:

• India should strengthen real-time fraud detection, authentication, cyber resilience, data protection and consumer grievance mechanisms.
• Payment-system operators should maintain high system availability because UPI has become a critical component of the national economic infrastructure.

Expanding International Linkages:

• India should prioritise interoperability with countries having substantial Indian diaspora populations, tourism flows and remittance corridors.
• Cross-border UPI linkages should be integrated with broader efforts to reduce the cost and settlement time of international retail payments.
