The Unstoppable Rise of UPI
Launched in 2016, UPI has become the backbone of India's retail payment system. It has transformed daily commerce, from street vendors to large retailers, by making bank-to-bank transfers instant, secure, and seamless. This growth was supercharged by the government's
policy to make transactions free for both users and merchants, a move designed to accelerate digital adoption across the country. By treating digital payments as a public good, UPI achieved unprecedented scale, bringing millions into the formal economy and making India a world leader in real-time digital transactions.
What 'Free' Actually Costs
While transactions feel free to the user, the infrastructure behind every payment has a real cost. Banks, payment service providers (like PhonePe and Google Pay), and the National Payments Corporation of India (NPCI) all incur significant expenses to operate and maintain the system. These costs include everything from server maintenance and cybersecurity to fraud prevention and customer support. For years, these costs were partly offset by government incentives, but industry experts argue these subsidies are not enough to cover the full operational burden, which is estimated to be many times the allocated amount.
The Zero-MDR Conundrum
At the heart of the issue is the Merchant Discount Rate (MDR), a fee that merchants typically pay their bank for processing a digital payment. Since January 2020, the government mandated a zero-MDR policy for all UPI and RuPay debit card transactions to encourage small businesses to adopt digital payments without worrying about costs. While this policy was wildly successful in driving adoption, it removed the primary revenue stream for the banks and payment companies that facilitate these transactions. This has led to growing concerns that the system, in its current form, is not financially sustainable for the private players who run it.
A Search for a Middle Ground
In response to the sustainability concerns, a major policy shift is underway. Starting October 15, 2026, an MDR of 0.4% will be applied to person-to-merchant (P2M) UPI transactions above ₹2,000. This move, backed by the Reserve Bank of India (RBI), is seen as a crucial step towards ensuring the long-term health of the payments ecosystem. The government and RBI have clarified that this charge is on the merchant, not the consumer, and all person-to-person (P2P) transfers will remain free. Furthermore, transactions under ₹2,000, which constitute the vast majority (around 96%) of merchant payments, will continue to be free of charge for merchants.
Impact on Merchants and the Ecosystem
The new tiered structure is designed to protect small businesses while creating a revenue stream for the payment industry. For transactions above ₹2,000, the 0.4% MDR is capped at ₹300, providing some predictability for businesses making large-value sales. Industry leaders have welcomed the move, stating it will allow them to reinvest in technology, security, and expansion, ultimately benefiting the consumer. However, there is an ongoing debate about whether merchants will absorb this cost or pass it on to consumers through slightly higher prices, a practice that banks have been directed to prevent.
