A proposed merchant discount rate, or MDR, on UPI transactions above Rs 2,000 could reshape payment behaviour among India's street vendors, according to a survey by the Indian School of Business. The findings point to a practical dilemma at the heart of the country's digital payments ecosystem: if small merchants are asked to absorb new transaction costs, many may either shift the burden to consumers or step back from UPI altogether.
The survey indicates that the response will not be uniform across markets. Vendors in Tier 1 cities appear more likely to pass on any additional charge to customers, while those in smaller cities and towns may be more inclined to avoid the fee by preferring cash. That split matters because street vendors are among the most visible and frequent users of UPI in India's daily retail economy, particularly for low-ticket purchases where speed and convenience have helped digital payments gain deep traction.
Cost Pressure Builds
The proposed framework would apply charges to payments exceeding Rs 2,000, introducing a new cost consideration for merchants that have largely benefited from low-friction digital acceptance. For street vendors, even a modest fee can be significant because margins are thin, sales volumes fluctuate, and many operate without the financial buffers available to larger retailers. The survey suggests that if the cost is imposed on suppliers or merchants, the immediate behavioural response may be defensive rather than adaptive.
That response could take two forms. Some vendors may add the charge to the customer bill, effectively making digital payments more expensive for buyers. Others may discourage UPI for larger transactions and steer customers toward cash, especially where they believe the fee would erode already narrow profits. Either outcome would weaken the seamless consumer experience that has made UPI India's dominant retail payment rail.
The findings also underscore a broader policy tension. UPI has been promoted as a public digital infrastructure with strong adoption incentives, but the introduction of MDR would mark a shift toward a more conventional payment economics model. For small merchants, the question is not only whether the charge is affordable, but whether the administrative and behavioural burden will outweigh the convenience of accepting digital money.
Awareness Shapes Behaviour
One of the most important takeaways from the survey is that awareness of the proposed framework varies widely by city tier. That matters because merchant behaviour is often shaped as much by perception as by policy. Vendors who understand the charge structure may adjust pricing or payment preferences in advance, while those with limited awareness may react only after costs begin to appear in practice.
In Tier 1 cities, where digital payments are more deeply embedded and customer expectations are stronger, vendors may be more willing to preserve UPI acceptance and simply pass on the cost. In smaller markets, however, the same policy could prompt a retreat to cash, particularly if vendors believe customers will resist paying more for digital convenience. The survey suggests that the policy's effect will depend heavily on local market structure, customer behaviour, and the extent to which merchants can absorb or transfer the charge.
For the broader mobility and urban commerce ecosystem, the implications are significant. Street vending is closely tied to commuter footfall, transit hubs, and informal retail clusters, where quick digital payments have become common. Any slowdown in UPI acceptance could affect transaction speed, record-keeping, and consumer choice in these high-turnover environments.
Policy Trade-Offs Ahead
The survey findings arrive at a sensitive moment for India's payments policy. UPI has become a flagship of the country's digital public infrastructure, and any move that changes merchant incentives will be closely watched by banks, payment firms, and small business groups. Supporters of MDR argue that a sustainable payments system requires a viable revenue model. Critics, however, warn that even limited charges can discourage adoption among the smallest merchants and reverse gains in formalisation.
For street vendors, the decision may ultimately be pragmatic rather than ideological. If the cost is small enough, some may absorb it or pass it on. If it is perceived as recurring and unavoidable, others may simply ask for cash. The survey suggests that the policy debate should not focus only on payment rails and bank economics, but on how millions of micro-merchants will respond at the point of sale.
That response will determine whether the proposed MDR framework becomes a manageable adjustment in India's digital payments landscape or a trigger for renewed cash preference among the country's smallest sellers.
