The Reserve Bank of India's deputy governor has pushed back against a growing market assumption that reintroducing merchant discount rates on higher-value UPI transactions will automatically drive consumers toward cash. Speaking on the policy shift set to take effect on October 15, Shirish Chandra Murmu said the relationship between digital payments and currency in circulation is more complex than a simple substitution effect.
Cash And Digital Coexist
Murmu's central argument was that cash and digital rails are not locked in a zero-sum contest. He noted that India has seen digital transactions expand sharply even as cash in circulation has continued to rise, underscoring that the two forms of money often serve different purposes. Cash, he suggested, is not only a payment instrument but also a store of value, which means its growth cannot be read as evidence that digital adoption is weakening.
That distinction matters as India prepares for a significant change in the economics of UPI acceptance. Under the revised framework, merchant discount rates will apply to UPI transactions above Rs 2,000, ending the fully zero-cost model that has helped make UPI the country's dominant retail payments rail. The policy is expected to affect merchants differently depending on ticket size, margins and customer behavior.
For the broader economy, the move is being watched as a test of whether India's digital payments ecosystem can mature into a more commercially sustainable model without losing user momentum. UPI's explosive growth has been built on convenience, interoperability and the absence of direct charges for most users and merchants. Introducing MDR on a subset of transactions may help payment providers recover costs, but it also raises questions about pricing, adoption and pass-through effects.
Auto Retail Exposure
The automotive and mobility sectors are among the most relevant to the new regime because they routinely process high-value transactions, from vehicle bookings and down payments to servicing, accessories and EV-related purchases. Dealers and mobility operators often rely on UPI for speed and reconciliation, especially in urban markets where digital acceptance has become a competitive necessity.
If merchants absorb the fee, the impact will show up in operating costs. If they pass it on, buyers may face subtle price adjustments, surcharges or incentives to use alternative payment methods. In either case, the policy could alter how dealerships structure payments for cars, two-wheelers, fleet services and electric vehicle infrastructure, where transaction values can easily cross the threshold.
Murmu's remarks are also a reminder that payment behavior is shaped by more than fees alone. Consumers choose cash, cards, UPI or bank transfers based on convenience, trust, merchant acceptance and transaction size. In high-value retail, even a modest fee may not be enough to reverse digital habits that have become deeply embedded in urban India.
Policy Test Ahead
The RBI's clarification appears designed to temper alarmist readings of the MDR decision while leaving room for the market to adjust. The central bank is effectively signaling that the policy should be viewed as a calibration of payment economics rather than a retreat from digitalization.
Still, the rollout will be closely monitored because UPI has become foundational to India's retail payment architecture. Any sign that merchants are discouraging digital payments, or that consumers are splitting transactions to avoid fees, could prompt fresh scrutiny. Conversely, if the fee is absorbed with little disruption, it would strengthen the case that UPI has reached a level of maturity where limited pricing can coexist with continued growth.
For now, the RBI's message is clear: higher cash in circulation does not automatically mean digital payments are losing ground. In Murmu's framing, India's payments landscape is expanding on both fronts, with cash and digital instruments serving different roles in a fast-changing economy.
