Unified Payments Interface (UPI) has historically operated with a zero Merchant Discount Rate (MDR), a policy mandated by statute.
The costs associated with UPI infrastructure have been borne by banks, payment applications, or through government subsidies.
Government subsidies for UPI have been inconsistent and have only partially covered the estimated operating costs of the system.
Concerns exist that introducing a fee could lead to large merchants passing costs to consumers and potentially encourage a shift back to cash, especially for low-value transactions of ₹10-₹20.
The discussion around introducing UPI fees coincides with ongoing trade negotiations with the United States Trade Representative (USTR), although the USTR's objections are not related to zero MDR.

Detailed Insights:
MDR is the fee a merchant pays its bank for accepting digital payments, typically a percentage of the transaction value for card transactions.
The current zero MDR policy, while promoting digital payments, places a financial burden on the exchequer and payment service providers.
"Pass-through" is an economic concept describing the extent to which merchants transfer increased costs to consumers through higher prices.
Introducing transaction costs could reduce the "money-like" utility of UPI, potentially shifting low-value transactions back to cash.
Despite free UPI, cash in circulation continued to increase, reaching approximately ₹42 lakh crore by 2026.
The USTR's 2026 report raised concerns about competition for American firms against RuPay, exclusion from credit on UPI, market share caps (40%), and data localization requirements.
Recommendations include legally protecting ordinary users and small merchants from fees, capping fees low for large merchants, and transparently managing proceeds for UPI system security through a payments authority.
