Trust At Stake
An IIT Bombay report has cautioned that the proposed merchant discount rate, or MDR, framework for UPI could undermine one of India's most widely used digital public infrastructures if introduced in its current form. The warning is significant because UPI has become synonymous with instant, low-cost payments and has helped drive a dramatic shift away from cash in urban and semi-urban India. Any policy change that alters that perception, the report suggests, risks creating friction in a system whose scale depends heavily on user confidence.
The report's central argument is not that the payments ecosystem should remain frozen, but that the pricing architecture around UPI must be rationalised with care. In a market where millions of consumers have been conditioned to expect seamless, near-zero-cost transactions, even a modest change in merchant charges can quickly become a public issue. The concern is that if merchants pass on costs, or if users begin to associate UPI with hidden charges, the platform could face reputational damage that would be difficult to reverse.
Merchant Fees Debate
MDR has long been a sensitive subject in India's digital payments policy. It refers to the fee merchants pay to accept card or digital transactions, typically shared among banks, payment networks and service providers. In the UPI context, the debate is more complex because the platform has been promoted as a public utility-like payment rail, backed by policy support to accelerate adoption and financial inclusion.
The IIT Bombay report appears to be warning that a blunt MDR implementation could distort that policy balance. If the framework is not carefully designed, smaller merchants may view UPI acceptance as less attractive, while larger merchants may seek to renegotiate payment acceptance costs across channels. That could slow the very digitisation gains that UPI has delivered over the past several years, particularly in high-frequency retail payments.
The report also underscores a broader policy tension: how to ensure the long-term commercial sustainability of payment infrastructure without eroding the trust that made UPI successful in the first place. India's digital payments ecosystem has matured rapidly, but its growth has relied on a simple user proposition: fast, convenient and largely free transactions. Once that proposition is weakened, the behavioural shift back toward digital payments may become less certain.
Policy Balance Needed
The report's caution comes at a time when policymakers are under pressure to support payment system economics while preserving inclusion and adoption. UPI's success has been built not only on technology, but on public policy choices that reduced barriers for consumers and merchants. The challenge now is to determine whether the ecosystem can absorb a fee framework without creating a perception that everyday digital payments are becoming costlier or less reliable.
For the automotive, EV and mobility sector, the stakes are also practical. UPI is increasingly embedded in mobility use cases, from fuel purchases and toll payments to charging stations, parking and app-based transport services. Any negative shift in public sentiment could affect transaction behaviour in these adjacent sectors, where convenience and speed are critical. Operators in mobility-linked businesses depend on frictionless digital payments to support quick turnover and customer confidence.
The report therefore points to a need for calibrated policy design, not abrupt monetisation. A rationalised MDR framework, if pursued, would need to protect consumer trust, preserve merchant adoption and ensure that payment service providers remain economically viable. The broader lesson is that digital public infrastructure can be highly scalable, but only so long as users continue to believe it is simple, fair and dependable.
As the debate evolves, the key policy test will be whether authorities can maintain UPI's mass appeal while addressing the commercial realities of operating a national payments network. The IIT Bombay report suggests that failing to strike that balance could invite negative sentiment at precisely the moment India is trying to deepen digital payment penetration across sectors and income groups.
