Governor Sanjay Malhotra said it is too early to determine who will bear the cost of UPI transactions, adding that "the costs have to be paid by someone" as policymakers debate a sustainable funding model.
The Centre is considering changes to the zero-MDR regime that could allow merchant charges on select UPI transactions, though no final decision has been taken on rates, thresholds or implementation.
The debate follows growing calls from banks, payment companies and Parliament's Standing Committee on Finance for a long-term revenue model to support investment in payment infrastructure, cybersecurity and the expanding UPI ecosystem.
