Is Free Digital Payments Sustainable? India's UPI Model and the Question of Who Bears the Cost

The Issue

India's Unified Payments Interface (UPI) has transformed the country's digital payment ecosystem. However, the sustainability of its zero-Merchant Discount Rate (MDR) model has come under renewed discussion.

In proceedings before the Supreme Court, the National Payments Corporation of India (NPCI) has reportedly questioned the long-term sustainability of a zero-MDR structure and defended a proposed merchant fee of 0.4% for certain transactions.

The debate raises an important question: who should ultimately bear the cost of maintaining a digital payment infrastructure that has become central to India's economy?

Why It Matters

UPI has helped expand digital payments across small businesses, retail establishments and individual users. Yet payment infrastructure requires continuous investment in technology, cybersecurity, transaction processing and dispute resolution.

A change in the MDR framework could have implications for merchants, payment service providers, banks and consumers. Equally, any fee structure must consider the financial capacity of small merchants and the broader objective of financial inclusion.

Our Perspective

The success of UPI should not be measured solely by the volume of transactions or the absence of transaction charges. Its long-term sustainability requires a balanced economic model.

The challenge is to ensure that the cost of maintaining digital infrastructure is distributed fairly without undermining accessibility, competition or the participation of smaller businesses.

India must preserve what makes UPI successful while ensuring that the system remains commercially viable.

Digital inclusion and economic sustainability must advance together.
